Summary
General Overview
The text summarizes the discussion of kal va-homer within the framework of the thirteen hermeneutic principles by which the Torah is interpreted, and distinguishes between several different argument structures. It argues that kal va-homer is not a necessary deductive inference, but rather a hermeneutic tool subject to refutation because it rests on assumptions of hierarchy and generalization. It critiques the view that kal va-homer is merely a “technical” formalism, and emphasizes that reasoning accompanies the derash even in “textual” principles like gezerah shavah. It then turns to gezerah shavah, presenting the conditions of similarity between subjects, the concept of mufneh, and the possibility of answering with a refutation, and suggests that the tradition required for gezerah shavah is not necessarily a transmission from Sinai of every detail, but rather an interpretive-linguistic tradition of the Sages about how to identify where comparison is appropriate.
Kal va-homer: Types and Examples
The text presents three types of kal va-homer. It defines one type as a kal va-homer built from a single datum together with a hierarchical assumption that yields a conclusion, and illustrates this with the verses “If her father had but spit in her face, would she not be humiliated for seven days?” and “Behold, the children of Israel have not listened to me, so how will Pharaoh listen to me?” It presents another type as the kal va-homer of “if two hundred includes one hundred,” in which the stricter case “contains” the lighter one, such as “If a man opens a pit or if a man digs a pit,” and similarly one who passes some of his children to Molech, from which it is argued that passing all of his children is certainly included. It cites the Maharsha in the second edition on Bava Kamma and Ginat Veradim as maintaining that such a kal va-homer cannot be refuted, and therefore “punishment may be derived through legal reasoning.” It argues that even in “if two hundred includes one hundred,” a refutation can be raised once we apply formal reasoning to reality, and illustrates this with the example of oranges in a basket and with the example of the Belgian law discussed by Vandervelde forbidding the purchase of two liters of wine, along with a judge’s ruling that acquitted someone who bought a larger amount on purposive grounds.
Talmudic Kal Va-homer and the Three Data Points
The text defines “Talmudic kal va-homer” as an argument that begins with three data points and derives a fourth law, and brings the example of tooth and foot and horn in the public domain and in the injured party’s courtyard from the Mishnah in the second chapter of Bava Kamma. It shows that two different kal va-homer tracks are possible: one track builds a hierarchy between domains from the laws of tooth and foot, and another builds a hierarchy between horn and tooth-and-foot from the laws of the public domain. It argues that these are two different arguments that can be refuted in different ways. It demonstrates that the direction also changes the result regarding half-damages and the topic of “it is sufficient for what is derived by legal reasoning to be like the case from which it is derived,” and explains that in Talmudic kal va-homer there is a prior stage of deriving a hierarchical relation, and only afterward using a structure similar to biblical kal va-homer.
Refutation, Deduction, and the Claim that Kal Va-homer Is Not Logical Necessity
The text states that the very existence of refutations proves that kal va-homer is not a necessary deductive inference, because a mathematical or logical proof is not subject to “refutation,” but at most to finding an error. It brings a principled example of refutation as finding a counterexample, similar to an empirical test of a scientific law, and explains that refutations of kal va-homer attack the hierarchical assumption or the generalization from one case to other domains. It critiques Rabbi Adolf Schwartz’s assumption (from the rabbinical seminary for advanced studies in Vienna) that kal va-homer is deduction, and presents a parallel claim that even gezerah shavah can seem deductive only if one introduces as premises a rule that is not itself logical.
Reasoning, Ta’ama De-kra, and Tradition in the Hermeneutic Principles
The text rejects the simplistic answer that the use of kal va-homer stems from the fact that “we do not derive law from the reason of the verse,” and proves from the Rif at the beginning of Bava Kamma that a reason is given for exempting tooth and foot in the public domain, and from Tosafot, which apply that reason to a halakhic implication in a case of a plank extending from a private domain to the public domain. It attacks the “Brisker naivete” of “you don’t ask why, only what,” and argues that there is no “what” without “why,” while noting that Tosafot HaRosh on Bava Metzia 90 draws a practical distinction according to which we derive law from the reason of the verse when the reason is clear, but do not spin speculative theories. It explains that sometimes substantive analysis alone does not decide the issue, and therefore the Torah authorized the use of tools like kal va-homer, where “we do not punish through legal reasoning,” but “to prohibit, yes,” and it describes the tradition as an anchor that places the tool in the toolbox, not as logic-free mechanics.
Critique of Brisker Formalism and Examples of “Illogical” Kal Va-homer
The text cites from “the Haggadah of Brisk,” in the name of Rabbi Chaim, the position that kal va-homer is a formal non-logical tradition, and presents as examples an aggadic kal va-homer of “ninety” and the kal va-homer of Rav Chiyya the earlier in Bava Metzia 3a: “let his own admission not be greater than the admission of witnesses.” It rejects the claim that there is no logic in kal va-homer, and states that where there is no logic, we do not make a kal va-homer; and if the logic is not clear, one must think further in order to find it. It adds that even after a refutation, sometimes the derivation continues if there is a logical consideration showing that the case under discussion resembles one side in a certain respect, and argues that “everything is subject to reason,” not to mechanical formalism.
Quotation and Explanation of the Paragraph on Page 24 about Kal Va-homer
The text reads the last paragraph on page 24: “In the principle of kal va-homer there is much to examine; kal va-homer is not just a simple ‘all the more so’…,” and interprets the author as rejecting an understanding of kal va-homer as “if two hundred includes one hundred,” where refutation is impossible, and concluding that kal va-homer is “a certain way of studying Torah that Moses our teacher received at Sinai.” It describes kal va-homer as an analogy constructed where the similarity in laws is not compelled, and where the refutation shows that the components are not similar, so one must examine each sugya on its own terms and understand the logic in the method of learning. It suggests seeing Talmudic kal va-homer as an analogy between “axes of hierarchy” and not only between the data points themselves, and identifies that as the point at which the refutation attacks.
Moving on to Gezerah Shavah: A Textual Principle with Logic
The text presents gezerah shavah as a textual principle, in contrast to kal va-homer as a logical principle, but states that both necessarily contain an element of reason. It says that in gezerah shavah, reason operates on two planes: in choosing the pair of words on which to make the gezerah shavah, and in deciding what to compare between the passages and what not to compare, even in light of the rule that “a gezerah shavah cannot be split in half.” It argues that one does not make a gezerah shavah regarding things that are not reasonably comparable, and illustrates this by saying that the gezerah shavah of “to her / to her” between a Hebrew slave and a woman does not lead to absurd conclusions like changing the spelling in the Torah, because the comparison is limited to what seems appropriate.
Mufneh, “Objections May Be Raised,” and the Tradition that “A Person May Not Derive a Gezerah Shavah on His Own”
The text cites the author’s statement that gezerah shavah exists between similar subjects, that similar wording points to similar content, and that between distant subjects “you never find a gezerah shavah.” It quotes his claim that “between connective words you never find a gezerah shavah,” so that we do not “turn the entire Torah into one law,” and remarks that he is not sure about this, attributing it to the need for a trigger and for logic. It explains the distinction in the Talmud between a gezerah shavah that is mufneh and one that is not mufneh: when it is mufneh, according to one view, we derive from it without refutation; and when it is not mufneh, “we derive and objections may be raised,” and if there is a refutation, the similarity falls away. It emphasizes that identifying mufneh itself depends on interpretive reasoning and on disputes over whether a word adds something or is superfluous.
The Book on Gezerah Shavah, Uniqueness, and the Development of Derash
The text brings up a book by Chernik, The Book of Gezerah Shavah, and a scholarly claim that early gezerah shavahs were built on unique words in the Bible, whereas in later periods they were built also on words that were not unique. It suggests that this expansion is not an “invention,” but an application of the same logic to additional cases, especially when the words are mufneh in both places, and emphasizes that there must be an interpretive reason for selecting the two words even when they appear elsewhere as well.
Nachmanides, Rashi, and the Dispute about “from Sinai”
The text presents the author’s determination: “Does this mean that gezerah shavahs were transmitted to Moses at Sinai? Absolutely not,” and brings his reasoning that there are disputes about gezerah shavah, and therefore they cannot have been received by Moses our teacher as closed details. It expresses some reservation about this argument, noting that the claim that “a law to Moses from Sinai is not subject to dispute” is itself an empirically problematic claim, and it discusses Rashi, who interprets “it is a learned tradition” as a law to Moses from Sinai. It describes an approach according to which the requirement of tradition in gezerah shavah is a linguistic-interpretive tradition of generations that “knew the ways of the language,” and not necessarily a transmission from Sinai of every application.
The Example of “Under… Giving… He Shall Pay Money” and Best-Quality Payment in Damages
The text concludes with the example: “Twenty-four primary categories of damages, all of them like the primary categories in that payment is made from the best quality… it comes from ‘under,’ ‘giving,’ ‘he shall pay money,’” and asks how we can be sure that these expressions are directed specifically to a comparison concerning “the manner of payment” of the best-quality produce. It states that we would not trust ourselves to decide this without a tradition from great Sages, but argues that when one looks carefully, one can understand the logic behind this choice. It suggests that one practical conclusion from the overall picture is the need to renew linguistic sensitivity in order to understand how the Sages worked, and perhaps even to broaden our understanding of the methods of gezerah shavah, and then it stops.
Full Transcript
[Rabbi Michael Abraham] The thirteen principles by which the Torah is interpreted, this is page 24. It starts on 23 and goes over to 24. We already saw the first two paragraphs that deal with kal va-homer. I know, but we need to finish this. So I’ll just summarize briefly. Last time we saw three types of kal va-homer. One kind of kal va-homer—I called it “all the more so,” though that’s not what he calls “all the more so.” It’s basically a kal va-homer that starts from a single datum, and on the basis of an “all the more so” reasoning reaches a conclusion. Like: “If her father had but spit in her face, would she not be humiliated for seven days?” So if her father spits in her face, she has to be humiliated for seven days; then the Holy One, blessed be He, all the more so—if He spits in her face, she should be humiliated for seven days. Or: “Behold, the children of Israel did not listen to me, so how will Pharaoh listen to me?” Meaning, yes—the assumption is that if Israel doesn’t listen to Moses our teacher, then Pharaoh certainly won’t listen to Moses our teacher. These lighter-and-stricter arguments come from a single datum, and there is some reasoning that establishes a hierarchy, and on the basis of that hierarchy we infer a conclusion from the single datum to an additional conclusion. Yes? Say with Pharaoh—the single datum is that Israel does not listen to Moses. The hierarchy is that Pharaoh is presumably less obedient, at least toward Moses, less obedient than Israel. So if Israel doesn’t listen to him, the conclusion is that Pharaoh also won’t listen to him. So we take one datum, a hierarchical assumption, and from that derive the conclusion.
[Rabbi Michael Abraham] A second type of kal va-homer—this is really all the kal va-homers in Scripture; I think all of them, or almost all if not all, are of this type, the “all the more so” kind. There is also a kal va-homer of “if two hundred includes one hundred,” which I also talked about last time. That’s a kal va-homer of inclusion. Meaning, if, say, we said that if for opening one is liable, then for digging all the more so—about a pit in the public domain. The assumption is—again, one datum: that for opening one is liable. The hierarchical relation here is different from the ordinary “all the more so,” because here the hierarchy seems necessary. Because digging—a person who digs a pit—in the act of digging there is also the act of opening. That is, digging is not only more severe than opening, but it contains opening itself, plus something more. Opening?
[Speaker B] What? It depends how you define opening.
[Rabbi Michael Abraham] I define it as removing the top layer over the pit.
[Speaker B] No, the question is whether that’s the right definition. Is it removing the top layer, or specifically removing the top layer over a pit that has already been dug?
[Rabbi Michael Abraham] It doesn’t matter. What difference does that make?
[Speaker B] If “over a pit already dug” is part of the definition, then digging does not include opening.
[Rabbi Michael Abraham] No, I think it still does.
[Speaker B] How can it remove it from over a pit?
[Rabbi Michael Abraham] It doesn’t matter. I do remove it—I just do it first. So what difference does it make?
[Speaker B] Over a pit that was already dug.
[Rabbi Michael Abraham] No, it doesn’t matter. It is over a pit that was dug—it’s over the pit that I’m digging. But I removed the cover and also dug the pit. So it can’t be that this doesn’t contain the act of opening. I don’t think that turns—
[Speaker C] —into being over a pit without removing a cover. What? At first it’s just a cover, underneath you dig, afterward you remove it.
[Rabbi Michael Abraham] And in the end you remove it. It’s the same thing.
[Speaker C] You’re not removing anything by digging.
[Rabbi Michael Abraham] Fine, so that’s just opening. So it’s just opening. But I’m saying that if I do digging, it contains opening. That’s a kal va-homer of “if two hundred includes one hundred.”
[Speaker C] You can dig underneath the cover. That’s what he’s saying.
[Rabbi Michael Abraham] No, but for digging underneath the cover you’re not liable. Right? So what? I’m talking about the digging for which one is liable. “If a man opens a pit, or if a man digs a pit”—so everything I’m discussing is only after you opened the cover. Once you’ve opened the cover, then it’s already at least like opening, if not more than that. So here you have a kal va-homer of “if two hundred includes one hundred.” Or I brought another example: someone who passes some of his children to Molech. Then apparently there is a kal va-homer that if he passes all of his children to Molech, he is also liable. Because if he passed all his children, then in particular he passed some of his children. So that’s a kal va-homer of “if two hundred includes one hundred.” It resembles “all the more so,” except for the fact—or not the fact, but the claim of some of the authors of the rules—that in such a kal va-homer there can be no refutation. I mentioned the Maharsha in the second edition on Bava Kamma, for example, who says this, and Ginat Veradim. There are several authors of methodological works who claim that in this kind of kal va-homer there can be no refutation. The Maharsha, for example, says that this is why in this kind of kal va-homer “we may punish through legal reasoning.” Because the whole reason we do not punish on the basis of kal va-homer is the concern that maybe there is a refutation, and then you imposed a punishment that was not really deserved. But with a kal va-homer of “if two hundred includes one hundred,” since there is no concern about refutation, here one may punish through legal reasoning. There are all kinds of assumptions here—I’m not going into them again now. We talked about that last time. That’s the second kind of kal va-homer.
[Rabbi Michael Abraham] I noted, I think, this point too: that even a kal va-homer of “if two hundred includes one hundred” can be refuted. It’s not true that it can’t be refuted, because whenever I apply logic to the world, there is always some additional assumption that can be refuted. I think I talked about this, right? Whenever I apply logic to the world, there’s always some additional assumption that can be refuted. I think I talked about it when I put, yes, oranges into a basket—the example for a mathematical rule. I put two oranges into the basket, then I add another three oranges, so in total there should come out five. Two plus three equals five. Okay? Now if in the end I find six oranges there after I did this, have I refuted the mathematical rule that two plus three equals five? Of course not. So what happened? I’ll look for some mistake in the experiment. Meaning, it’s not that I’ll ever get two plus three not equaling five. That means the mathematical rule can never be refuted. But whenever I apply it to the world, there is always some addition—and the addition in this case is the assumption that adding oranges to a basket is described by arithmetic addition. And it could be that that’s wrong. That’s an assumption in physics, not a mathematical assumption. The mathematical assumption is that two plus three equals five. But the fact that I apply this to adding oranges to a basket—that is already an assumption in physics. In physics maybe I’m mistaken. And I gave the example there that if, for example, I’m adding vectors—forces—then ten plus ten does not necessarily equal twenty; it depends on the direction of the force. So what does that mean? It means that the rule of arithmetic addition does not correctly describe adding forces. That’s all. But I didn’t refute the rule that ten plus ten equals twenty. Therefore whenever I apply it to something in the world, I’m really assuming that this mathematical theory or this mathematical theorem is applicable to these real-world circumstances, and that, in principle, can be refuted.
[Speaker D] But why is that relevant to “if two hundred includes one hundred”?
[Rabbi Michael Abraham] So I’m saying that “if two hundred includes one hundred” is basically a mathematical rule, that one is included in two hundred.
[Speaker D] No, I’m claiming it’s not a mathematical rule. Why? “If two hundred includes one hundred” means this: if, say, one hundred has such-and-such a law, when you did two hundred you did one hundred.
[Rabbi Michael Abraham] Of course—that’s what logic is. Let’s think about a logical inference. I understand, I understand.
[Speaker D] How can there be a refutation here?
[Rabbi Michael Abraham] So let me show you, let me show you. When you did—when you think about a logical inference, all right? All human beings are mortal, Socrates is a human being, therefore Socrates is mortal. You understand that this is exactly “if two hundred includes one hundred”? Because basically the two hundred is like all humanity—“all human beings are mortal”—and the one hundred within it is Socrates, who is one of them. Right? That’s parallel to “if two hundred includes one hundred.” It’s a logical rule. Logic and mathematics, for the moment, are the same thing for me. Okay? Now, when you apply it to the world, there can be a refutation—even there, even in “if two hundred includes one hundred.” I think I brought the example last time of the law of Vandervelde. The Belgian law that said it was forbidden to buy two liters of wine. I didn’t talk about that, I think, right? The law was intended to make sure that workers bringing home their weekly wages would bring the money home and not spend it on wine in the pub. So it was forbidden to buy two liters of wine, because that was roughly the amount of a worker’s weekly wage there. Now a certain worker bought, I don’t know, ten liters. They took him to court. He bought ten liters—or someone sold ten liters, I don’t remember exactly what happened there, but let’s say that’s the principle. The judge acquitted him. Why did he acquit him? He said: if buying two liters is forbidden because we don’t want you spending your weekly wages in the pub, but if someone decides to invest his savings in wine and wants to become a wine merchant, who can forbid that to him? It’s his right. Freedom of occupation, right? A basic law. Meaning, you can engage in wine trade, and who can forbid such a thing? So right now it doesn’t matter whether we accept that interpretation or not—you can debate it—but on the principled level you see here too that someone who buys ten liters has, within that, bought two liters; and if it’s forbidden to buy two liters, then he violated the prohibition. But there is always some further assumption behind it. The assumption that two is always contained within ten—there’s no refutation of that. But when you want to turn this into a law, into something that deals with reality—not mathematics, but something that says something about life, about reality—there is always some additional assumption.
[Speaker D] But if he bought two liters and claimed, “I’m buying this for commerce, I’m not really buying this, I—”
[Rabbi Michael Abraham] “—want to become a wine merchant, this is the money I have now, I’m buying two liters.”
[Speaker E] Then no, then they wouldn’t allow it.
[Rabbi Michael Abraham] They wouldn’t allow it. They wouldn’t allow it. No. If he bought a hundred liters—
[Speaker D] Because, because—who knows? Anyone can say he’s buying it for commerce. No, I’m saying again, it’s not important. You can disagree with the judge’s interpretation. Here because here it gets into something that’s motive-based.
[Rabbi Michael Abraham] Exactly—that’s always it, that’s the extra assumption, always. Always. Meaning, the example—let’s look at our own example. I think I talked about this too, about this kal va-homer where the Maharsha claims there’s no refutation and therefore you can punish through legal reasoning. It seems to me that if I didn’t bring it, I’ll say it now: even that itself has a refutation. After all, there is another explanation for why we do not punish. There’s another explanation for why we do not punish through legal reasoning. For example, that the punishment given for the lighter offense is not enough for punishing someone who committed the more severe offense, and therefore we don’t impose the lighter punishment. That’s another explanation for why we do not punish through legal reasoning. Let’s see what happens in terms of “if two hundred includes one hundred.” Say, someone who passes some of his children is punished; someone who passes all of his children is not punished. Fine? So what does that mean? It means that the punishment given for “some” is not sufficient for one who passed all of his children, and therefore one who passed all of his children is not punished. Now again, that’s “if two hundred includes one hundred”: punish him for having passed some of his children, and about the rest we’ll talk later. No—sometimes there can be a situation where the punishment for the greater case already requires an accounting with the Holy One, blessed be He. And again, one can debate this, but it shows that at least on the principled level, “if two hundred includes one hundred” is open to refutations. Once it starts being applied to something that is no longer purely formal—just logic or theoretical mathematics—but starts speaking about some content, then you already run the risk of a refutation.
[Speaker B] Yes, but even on the formal level of refutations, you can in principle find them even without using kal va-homer. Even if you just connect a case to reality, like interpreting a verse in its plain sense, you can also find refutations. I don’t understand the point.
[Rabbi Michael Abraham] That’s obvious. I wasn’t talking about that. That’s simple. But the question is how it can be that even a kal va-homer of “if two hundred includes one hundred” can have refutations. I’m claiming that even there it can—there one might have thought that it couldn’t.
[Speaker B] Every kal va-homer of “if two hundred includes one hundred” is a kind of applying the verse to something.
[Rabbi Michael Abraham] A kal va-homer of “if two hundred includes one hundred” is a kal va-homer from the part to the whole—what does that have to do with a verse now? Say, some of the children to Molech and all of the children to Molech. So what do you mean? I don’t understand the claim.
[Speaker F] All the children is more lenient, because with some he has to choose.
[Rabbi Michael Abraham] There you go—another sophistic refutation. Why didn’t he take both? Yes, so there, that’s the refutation—that itself is a refutation. There, another refutation. Fine? That’s a refutation. That’s exactly the point. Meaning, whenever we apply mathematics or logic to life, a refutation can arise. Again, that doesn’t mean there always will be a refutation.
[Speaker B] Yes, but I don’t understand. You can always say that a refutation can arise even without using kal va-homer. Even if I say that if he sacrifices some of his children he is punished, then a refutation can also arise to the claim that this also applies to three of his children if he has four.
[Rabbi Michael Abraham] Of course. So what’s the question? I didn’t understand. So—
[Speaker B] What meaning is there to saying that the refutation is on the “if two hundred includes one hundred”? In every case I can raise a subjective refutation.
[Rabbi Michael Abraham] But even on an inference of “if two hundred includes one hundred,” where you would have thought there could be no refutation, there is a refutation. In any other interpretation, of course there can be a refutation—obviously. That doesn’t need any new claim; it’s obvious. I wasn’t talking about that at all. Who would say otherwise? Any reasoning of ours can have a refutation—that’s obvious. On the contrary, with “if two hundred includes one hundred” we would have thought there couldn’t be one. I’m saying that even on such an inference, which is a logically necessary inference, there can be a refutation. You can ask what the rationale of this explanation is, on account of which we don’t punish. That maybe you can ask. Because if with kal va-homer we don’t punish because maybe there is a refutation, then why do we punish on the basis of every other interpretive rule? There too there can always be a refutation. That’s an excellent question—but that already belongs to the topic of “we do not punish through legal reasoning.” I’m not dealing with that right now. For me it’s only an example. Fine? Therefore I really think that explanation is not correct, but there are later authorities who give that explanation, so okay. So that’s the second kind of kal va-homer, which also starts from one datum, except that the hierarchical relation is a relation of inclusion. If I’m right that even such a relation is subject to refutation, then it’s simply not a second type at all—it’s the same type. Meaning, there’s no difference. Only someone who claims that there can be no refutation there defines it as a separate type of kal va-homer. But for me, both of them are a kal va-homer that starts from one datum with a hierarchical relation.
[Rabbi Michael Abraham] A third kind of kal va-homer is what I called Talmudic kal va-homer. Usually in the Talmud, kal va-homer is neither this nor that. The kal va-homers that appear in the Talmud are of another type, a third type, second, whatever you want to number them. It starts from three data points, not one. For example, with tooth and foot in the public domain and in the injured party’s courtyard, the Talmud derives a kal va-homer. It says: if tooth and foot—which are exempt—meaning, if horn—which is liable, sorry—if tooth and foot, which are exempt in the public domain, are liable in the injured party’s courtyard, then horn, which is liable in the public domain, is certainly liable in the injured party’s courtyard. Tooth and foot and horn are categories of damagers, for those who don’t know—types of damage caused by my animal. And the question is whether I’m liable to pay when my animal caused damage of this sort or that sort. Horn is damage with intent to harm—unusual damage with intent to harm; there are some distinctions here. And tooth and foot are damage where it either eats something or tramples while walking, regular damage—not unusual damage, not damage with intent to harm. That’s tooth and foot.
[Rabbi Michael Abraham] Now the rules are: we have three data points. Tooth and foot in the public domain are exempt; horn in the public domain is liable—ignoring for the moment that it’s only half, liable, yes? Tooth and foot in the injured party’s courtyard are liable. And the question is: what is the law for horn in the injured party’s courtyard? That isn’t written. So the Talmud—the Mishnah actually, in Bava Kamma chapter 2—brings a kal va-homer, yes? If tooth and foot, which are exempt in the public domain, are liable in the injured party’s courtyard, then horn, which is liable in the public domain, certainly should be liable in the injured party’s courtyard. What kind of kal va-homer is this? It’s neither of the first two types. It’s a kal va-homer that starts from three data points, not one. Tooth and foot exempt in the public domain, tooth and foot liable in the injured party’s courtyard, horn liable in the public domain. And one thing—I don’t know, and I have a conclusion that I’m looking for. Yes? What is the law for horn in the injured party’s courtyard? And then I build on those three data points an argument that brings me to the conclusion, which is a fourth proposition. That’s already a difference.
[Rabbi Michael Abraham] Now how is it still related to kal va-homer? You can take two out of those three data points and use them to build a hierarchical relation. Once I build a hierarchical relation from two data points, I’ve returned to the biblical kal va-homer. I have one datum; from the other two I built a hierarchical relation, and now from that datum I infer a conclusion. Fine? In the end I get to an argument that is like the biblical one, but there is one prior step—that’s the difference. For example, in the case of tooth and foot and horn: I look at the laws of tooth and foot—exempt in the public domain, liable in the injured party’s courtyard. What hierarchical relation can I derive from those two data points? That in the injured party’s courtyard it is easier to impose liability than in the public domain, right? And now I take the third datum: horn is liable in the public domain. So if in the injured party’s courtyard it is easier to impose liability, then horn, which is liable in the public domain, certainly will be liable in the injured party’s courtyard.
[Rabbi Michael Abraham] By the way, I can also do this with the two data points that concern the public domain. Here I used the two data points of tooth and foot to derive a hierarchical relation from them. But I can do a different kal va-homer, built on the two data points of the public domain: horn is liable and tooth and foot are exempt. What is the hierarchical relation? That with horn it is easier to impose liability than with tooth and foot—a hierarchy between horn and tooth-and-foot, not between domains. Then I say that in the injured party’s courtyard, if tooth and foot are liable, and horn is easier to make liable than tooth and foot, then horn too will be liable. Okay? So that’s another kal va-homer, and plainly it is a different argument. Because think, for example—now I will put the “half” back in—horn in the public domain is really only liable for half-damages, not full damages. Now the question is what horn will be in the injured party’s courtyard. That depends on which direction we read the kal va-homer, right? If we use the two data points of tooth and foot, then the conclusion is that the injured party’s courtyard is more stringent than the public domain, easier to impose liability there than in the public domain. So if horn in the public domain is liable for half, in the injured party’s courtyard—no, half. Because you have the rule “it is sufficient for what is derived by legal reasoning to be like the case from which it is derived.” How much will you give? Maybe three-quarters? Maybe half plus epsilon? You don’t know where to stop. The minimum is half; I don’t know how much more. That’s called “it is sufficient for what is derived by legal reasoning to be like the case from which it is derived.” I know it’s more than half, but I don’t know how much more, so I say: fine, half.
[Rabbi Michael Abraham] But if we take the opposite side—if you say that horn is more severe than tooth and foot—exactly. If I learn from the laws of the public domain that horn is more severe than tooth and foot, because horn is half and tooth and foot aren’t liable at all, now let’s move to the injured party’s courtyard: tooth and foot are liable for full damages, and horn is more severe than tooth and foot—then horn comes out as full damages, not half. So that is apparently a proof—although it’s actually not correct, but never mind, we learned this when we studied the principles—that this is really two different arguments. It’s not the same argument. It’s not two formulations of the same argument. It’s simply two different arguments. In every structure like this of Talmudic kal va-homer, you can formulate two arguments that are different. Meaning, say, one argument will be refuted if we show that the injured party’s courtyard is not more severe than the public domain, but that in no way refutes that horn is more severe than tooth and foot. And vice versa: if I refute the claim that horn is more severe than tooth and foot, that doesn’t affect the kal va-homer that assumes that the injured party’s courtyard is more severe than the public domain. So these are really two arguments. They are refuted differently, they assume different assumptions, they are something entirely different.
[Rabbi Michael Abraham] What is common to both these arguments is that they are both built on the same logic. I have three data points—sorry—two of them I use to derive a hierarchical relation, one I use as an anchor for the kal va-homer, and the hierarchical relation takes me from the additional datum to the conclusion. In the second stage, that’s already exactly like the biblical kal va-homer, right? Biblical kal va-homer is one datum and a hierarchical relation that I know directly. In Talmudic kal va-homer, I don’t know the hierarchical relation; I derive it from two of the data points. But after I derived it, then I’ve returned to biblical kal va-homer. Fine?
[Rabbi Michael Abraham] Now what happens in all these kal va-homers? As I said before, including the kal va-homer of “if two hundred includes one hundred”—all of them can be refuted. They are not logically necessary inferences. If it were a logically necessary inference, it could not be subject to refutation. There is no refutation of a logical inference. A mathematical proof has no refutation. You can find a mistake in it, but not a refutation. Meaning, you can’t submit it to an empirical test and see whether it stands the test. If it doesn’t stand the test, then apparently your empirical assumption was wrong, but that has nothing to do with the mathematical theory. If the proof is valid, if there is no error in it, then the conclusion follows from the premises. There is no arguing with that. So the fact that there are refutations of kal va-homer means that kal va-homer is not a deductive inference; it is not a logically necessary inference.
[Rabbi Michael Abraham] There are books by a Jew named Adolf Schwartz, Rabbi Adolf Schwartz, from the seminary for advanced rabbinical studies in Germany—in Berlin, I think he was, or in Vienna, sorry, in Vienna—who already at the beginning of the 20th century wrote three studies on the principles by which the Torah is interpreted. He wrote them in German, but one or two of them, I think, were translated into Hebrew—on kal va-homer and on gezerah shavah, I think, were translated into Hebrew. He also has one on general and particular, but that wasn’t translated. And he assumes that kal va-homer is a deductive logical inference, meaning necessary. That’s hard to assume, first of all because if so, then why do we need a tradition regarding the use of the hermeneutic principles? Logical inferences—I don’t need permission from the Holy One, blessed be He, to use them. I use logical inferences in all areas of Jewish law.
[Speaker I] We said at the beginning of this class that maybe for the buyer they don’t complete it that way, they complete it in another way.
[Rabbi Michael Abraham] What do you mean?
[Speaker I] I didn’t understand. If, say, the Torah doesn’t say what the law is in such-and-such a case, it does say—
[Rabbi Michael Abraham] A kal va-homer of “if two hundred includes one hundred.” Okay. But for him, all kal va-homers are like that. He says that kal va-homer is deduction. If kal va-homer is deduction, then the Torah does say it.
[Speaker I] But there are many logical ways of carrying out the principle called kal va-homer. And now we said there are three or four. Okay, so maybe some of them really are necessary.
[Rabbi Michael Abraham] No, he claims that the whole logic of kal va-homer is deduction—you can’t, it’s necessary. Now that really is a strange statement, because we know there are refutations of kal va-homer.
[Speaker I] Once you make a refutation to a kal va-homer, then you are refuting one of the premises or—
[Rabbi Michael Abraham] No, you’re refuting the generalization to the hierarchical relation. I’ll get to that in just a moment.
[Speaker I] Meaning, you can say, “What about X, where such-and-such, such-and-such”—but again, that’s already what you said: when you bring this logical structure down into the real world, it’s not exactly the same thing. But the argument as a logical structure is logical—that is, it’s valid.
[Rabbi Michael Abraham] No, but then it’s devoid of all meaning. Then for me gezerah shavah too is a logically necessary inference. Why? Very simple. Here, I’ll show you a logically necessary argument that leads to a conclusion of gezerah shavah. Premise A: it says “under” in the payment for an ox that gored a slave, okay? “In place of… he shall surely pay,” “in place of the ox,” something like that. It says “under” also in various other damagers, no matter which; they derive a gezerah shavah. He’ll bring it here later, in Bava Kamma 5, where the Talmud derives that one pays from the best quality in every case. So I’ll present it as a deductive argument. I say: when there are two identical words in two passages, you must compare them.
[Speaker I] That’s an innovation. That itself is an innovation. That’s not logic. If it’s a valid rule, a rule that is always true—
[Rabbi Michael Abraham] Exactly, but that’s precisely the point. So in kal va-homer too, that’s how it is. In kal va-homer too there is an innovation that is not logic, that says that if tooth and foot are more severe than horn—sorry, that horn is more severe than tooth and foot in the public domain—then apparently it is more severe than tooth and foot in everything, in every domain, including the injured party’s courtyard. That is exactly the point where kal va-homer ceases to be logic. You can always translate it this way: if you insert the data that were given to us from Sinai and call them a premise, in the end it will always come out as a deductive argument. That’s obvious, but that’s exactly the problem. Anyway, fine, that’s an anecdote. I think either he didn’t fully understand what a syllogism is, or he didn’t mean what I understood him to mean. I don’t know. But it can’t be. It’s not a logically necessary inference. So there are refutations of it.
[Rabbi Michael Abraham] What do the refutations attack? The refutations always attack the hierarchical assumption. Sometimes there is something that is not really a refutation—simply one of the data points turned out not to be correct. It turned out you started from a wrong datum. That’s not a refutation; that’s just finding a mistake. A mistake of that kind can also be found in a mathematical proof: you made an error in the move from here to there. That’s not a refutation. A refutation means that your entire inference is correct, but when I put it to the test, I find a contradiction—like when we put a scientific theory to the test. Right? So the scientific theory says that every object with mass falls toward the earth. What is a refutation in that context? I take, say, this thing, let go of it here, and it doesn’t fall. That would be a refutation of the scientific law. Not that I found a mistake in the inferential path of the scientist who formulated it—Newton, yes? Rather, I put it to an empirical test and I found a counterexample. Now a refutation of kal va-homer is like that too. A refutation of kal va-homer is not finding an error in the inferential path. Rather, I show a case where we see the opposite, or a counterexample. Meaning, you assume that horn is more severe than tooth and foot? Fine, I’ll show you that somewhere else horn is not more severe than tooth and foot, but rather more lenient. For example, horn is liable only for half on the first goring, whereas tooth and foot are liable for full damages from the very first act of damage. Just as an example. Incidentally, the Talmud there does not make that refutation, and that itself is a question why. But for example, that’s an inference—that’s a refutation. This refutation does not attack the way I carried out the kal va-homer. It only shows me that it doesn’t stand the empirical test. You want to claim, you have a general theory: every object falls toward the earth. You have a general theory: horn is always more severe than tooth and foot. That theory I put to an empirical test, meaning I check the data and see—not true, not always. There are aspects in which horn is not more severe than tooth and foot.
[Speaker G] But then you—I think the a fortiori argument is valid when all the conditions are the same.
[Rabbi Michael Abraham] Exactly. What do you mean?
[Speaker E] If there is—
[Speaker G] The case where we’re talking about the same conditions and in the same place, that’s not—
[Rabbi Michael Abraham] The same conditions? Tooth and foot versus horn—that’s not the same conditions.
[Speaker G] No, but when you bring an example from somewhere else where horn is less severe, then over there the conditions are different. Meaning, first you have to look. No, I agree, I’m just— you know, if you run one hundred meters—if you walk one hundred meters in ten seconds, then you’ll run it in less than that, right? But then I’ll tell you, not true, because if you run then you’ll fall because there are rocks there, so you won’t be able to do the hundred meters by running. Okay, but then I changed the place.
[Rabbi Michael Abraham] Obviously. That’s exactly what a refutation does. Let me explain, I’ll explain it.
[Speaker G] The question is whether a refutation can show that I’m doing it under those conditions. I’m talking about a place where the road is smooth and it runs and you can run and you can walk.
[Rabbi Michael Abraham] That’s a trivial statement, but it won’t help you for an a fortiori argument. You don’t need to refute it. You won’t be able to derive anything from it.
[Speaker G] Meaning, you won’t learn anything new from it.
[Rabbi Michael Abraham] You won’t learn anything from it, because anything you learn from it is always a generalization. That’s what a refutation does. What does a refutation do? Let’s now look more closely at our a fortiori argument. Let’s take this a fortiori argument again. I learned that horn is more severe than tooth and foot from the two data points in the public domain, right? Notice that there’s a generalization here, because all I really know empirically is that in the public domain horn is more severe than tooth and foot. But I want to apply that to the injured party’s courtyard. I say, ah, so if in the public domain it’s more severe, then apparently in every respect it’s more severe. If so, then in the injured party’s courtyard too it’s more severe. That’s how the a fortiori argument is built, right? Now I find a refutation. I say that horn, let’s say, on the moon is less severe than in the injured party’s courtyard. Just as a logical example. Okay? On the moon, horn incurs no liability, while tooth and foot do incur liability. Fine? So that’s a refutation. What does that refutation do? That refutation says: it is not true that horn is always more severe than tooth and foot. Sometimes yes—in the same circumstances, meaning in the public domain—but sometimes not. And now the question is: which “sometimes” fits the injured party’s courtyard? Does it fit the “sometimes” of the public domain, or the “sometimes” of the moon? And what lies behind all this is the following question: there is some aspect—because that’s what lies behind the dry data—there is some aspect of horn in which it is more severe than tooth and foot, and another aspect in which apparently it is less severe. The aspect in which it is less severe is relevant on the moon, and the aspect in which it is more severe is relevant in the public domain. And now I ask: in the injured party’s courtyard, which of those two aspects is the relevant one? If it’s the aspect of the moon, then the a fortiori argument collapses. If it’s the aspect of the public domain, then the a fortiori argument stands. But since I don’t know, I have no inference. Since you can’t draw a conclusion—maybe yes, maybe no. A refutation only has to show that the conclusion is not necessary. It doesn’t have to show that it’s false. Otherwise it wouldn’t be a refutation; it would be an anti-refutation. Meaning, it would be a counter-proof. Because then I’d also have reached some conclusion—
[Speaker H] The opposite proof.
[Rabbi Michael Abraham] Exactly. And I’d already have reached a conclusion about what the law is regarding horn in the injured party’s courtyard. That too is an a fortiori argument. It’s just the reverse direction, from severe to lenient. In other words, I reached the opposite conclusion. But a refutation always means you can’t reach a conclusion; the question remains open. That’s called a refutation.
[Speaker H] From an a fortiori argument you learn only from the refutation, because from an a fortiori argument that wasn’t refuted you didn’t learn anything, since it was all hidden in the assumptions.
[Rabbi Michael Abraham] Right. Right. From the refutation, yes—you learned that what you thought was hidden isn’t really hidden. We’re still dealing with assumptions. I think I once talked about this: the only argument from which we actually learn something is the argument in which we lost.
[Speaker G] That’s what Maimonides says. Yes, he says that if someone defeats you—
[Rabbi Michael Abraham] A wise person.
[Speaker D] Like the Rebbe always used to tell us, if the experiment failed, it didn’t fail—it succeeded,
[Rabbi Michael Abraham] it taught us something else,
[Speaker D] the experiment that succeeded, we learned nothing from it.
[Rabbi Michael Abraham] So a refutation basically teaches us that the picture of the hierarchy is more complex than we thought. The hierarchy isn’t so simple. There is an aspect according to which horn is more severe than tooth and foot, and an aspect according to which it isn’t. But since the relationship between horn and tooth and foot is more complex, now go figure out what is relevant in the injured party’s courtyard. By the way, sometimes there is a logical consideration that tells us which of the two relationships is relevant to the injured party’s courtyard, and then we’ll continue using the a fortiori argument despite the refutation. Because reasoning will tell us that it is more similar—exactly—if I can put my finger on the fact that it is more similar to what happens in the public domain than to what happens on the moon, then I’ll make the a fortiori argument. There are examples of this. I’ll make the a fortiori argument even though there is a refutation against it.
[Speaker J] But why, in a case where I’m missing this law about horn in the injured party’s courtyard, would I even resort to an a fortiori argument? Why not analyze the issue on its own terms? Why is horn liable here and tooth and foot exempt there? Because horn was intentional and tooth and foot were not intentional. And in the public domain, if I obligate someone, that’s much more severe—or less severe—than in the injured party’s courtyard, on its own terms. Not because of comparisons and not because of an a fortiori argument; just logical analysis.
[Rabbi Michael Abraham] The simplest answer to that is that we do not derive Jewish law from the reason of the verse. Once you have data, and then you start thinking why it is so—you do not derive Jewish law from the reason of the verse. This is the dispute between Rabbi Shimon and Rabbi Yehuda, and in Jewish law we rule like Rabbi Yehuda, that we do not derive Jewish law from the reason of the verse. But that’s a simplistic answer, and it’s not correct.
[Speaker I] Most of the time, whenever there is some specific exposition or one of the principles by which the Torah is interpreted, there’s some obvious logic there.
[Rabbi Michael Abraham] I already said this, and I’ll say it again: I said that answer is not correct, even though it’s the easiest one to give. Why isn’t it correct? I’ll prove it from the very case itself. The Rif, at the beginning of Bava Kamma, explains why tooth and foot are exempt in the public domain. It’s actually a pretty reasonable explanation; it also appears in Maimonides in a slightly different version, and several medieval authorities bring it, also the Rosh. A person normally walks in the public domain with his animal, and other people need to understand that animals walk there, and if you place produce there, then know that animals pass there. Nobody is supposed to restrain his animal in the public domain; it belongs to all of us. Let everyone guard his own property. Fine? So that’s a very simple explanation, and the Rif brings it as the reason that in the public domain tooth and foot are exempt. And more than that—not only does he explain the reason of the verse; the Rif is not a Bible commentator, the Rif is a halakhic authority. When he brings this, the assumption is that it has halakhic implications, and Tosafot indeed derives a halakhic implication from it. Tosafot argues that if there is a plank lying across from a private domain into the public domain, and the animal walks in the public domain and damages produce that is in the injured party’s courtyard by moving that plank, then because of the Rif’s reasoning that too would be exempt. Because all in all it is walking in the public domain, and it has a right to walk there. Even though the produce is in the private domain. So leave the details aside for the moment, but I’m showing you that the Rif did derive Jewish law from the reason of the verse in the very topic we are dealing with. Not only in general—because as you rightly said, everyone always derives from the reason of the verse—here the Rif does it on this very topic. There really was Shlomo Meir—what do you mean, he derives from the reason of the verse and so on—but people do this, all the time. The Brisker naivete that says we don’t ask why, only what—that’s nonsense. There is no “what” without a “why.” There’s no such thing. If you don’t know why, how do you know what? What is written explicitly in the Torah—fine, I understand. Almost nothing is written explicitly in the Torah. Every small implication you make, every inference, every interpretation, always presupposes some understanding of what’s there; otherwise how do you do it? You could generalize every matter in a thousand different ways. Every generalization assumes, either implicitly or explicitly, some kind of understanding. There’s no such thing. You cannot define the “what” without asking the “why.” People always say there’s a difference between the definition and the reason. Without the reason there is no definition. It’s just an artificial distinction. You can’t do that. So what does it really mean that we do not derive Jewish law from the reason of the verse? Great question. I don’t have a good answer. Apparently it means you don’t go too far with deriving from the reason of the verse, or something like that. The Rosh—Tosafot HaRosh in Bava Metzia 90—writes there that if the reason is clear, then yes, we do derive Jewish law from the reason of the verse. So what did he really mean? That “we do not derive Jewish law from the reason of the verse” means we don’t make speculations that are too far-reaching with these analyses. But where it is clear that this is the reason, then yes, you do derive from the reason of the verse. Where? Ah, that’s why I said it isn’t such a good answer. The better answer is that we can’t always make that analysis. Try to make that analysis here, for example—it won’t be simple. It’s not simple because when you make the calculation in the public domain, the whole situation there is different from the situation in the injured party’s courtyard, because in the public domain the animal is in fact walking. So I say tooth and foot are damage that happen in the normal course of walking, so they are exempt. True, but horn is intentional damage. Intentional damage might be something for which even in the public domain you have to pay. Therefore in the public domain horn is more severe than tooth and foot. Now let’s try to apply that to the injured party’s courtyard. In the injured party’s courtyard I don’t know what to do with that. In the injured party’s courtyard you’re not allowed to be there—not to eat and not to gore. So is it more severe or less severe? I don’t know. Maybe in the injured party’s courtyard there would be liability for half, maybe there would be no liability at all, maybe full liability—I don’t know. I can argue in either direction.
[Speaker J] Isn’t it clear that your duty of care is much greater in the injured party’s courtyard?
[Rabbi Michael Abraham] No, but I’m talking about horn versus tooth and foot, not about the injured party’s courtyard versus the public domain. I’m now talking about horn versus tooth and foot. I don’t know how to establish a hierarchical relation between them with respect to the injured party’s courtyard. Now again, this is only an example—
[Speaker J] So you would say—
[Rabbi Michael Abraham] Fine, so establish it on the axis of injured party’s courtyard versus public domain, not on the axis of horn versus tooth and foot. For that I wouldn’t have gone to make this comparison, but that’s why I brought this in the year when we studied the interpretive principles—I showed that it is in fact the same argument. I can translate one into the other. You can’t do one without the other. But for that I need a bit of mathematics. But never mind; for purposes of the example this argument is enough for me. When you want to check the relation between horn and tooth and foot, it’s not so simple; you can’t always really understand from what happens in the public domain what happens in the injured party’s courtyard. And therefore you are basically making some formal assumption that says that if this is more severe than that, then you may apply it also to the injured party’s courtyard. If it doesn’t make sense, then you don’t do it. Contrary to what the Briskers say. You don’t do it when it doesn’t make sense. But where it is reasonable—even though, again, if I had to do it without permission from Sinai to make an a fortiori argument, maybe I wouldn’t do it, because who knows, maybe it could go either way. That’s why you need permission from Sinai. In other words, the Holy One, blessed be He, tells me: yes, work with this logic. There is room to doubt it; that’s okay. To punish on that basis—no, we do not derive punishments from logical inference. But to prohibit—yes. It’s good enough to prohibit. Okay? So that’s why the a fortiori argument works in a somewhat formal way. In the background there is some understanding—it’s not true otherwise. People bring examples of a fortiori arguments—I think I told this, I don’t remember if I told it—that in the Brisk Haggadah at the end—did I tell this? In the Brisk Haggadah, at the end, when it discusses “Who Knows One,” that refrain, when they get to “thirteen middaya.” What does “thirteen middaya” mean?
[Speaker H] The thirteen interpretive principles.
[Rabbi Michael Abraham] Right. Among the Hasidim, what is “thirteen middaya” in Hasidic Haggadot? The thirteen attributes of mercy—“The Lord, the Lord, compassionate and gracious.” For the Brisker, “thirteen middaya” means the thirteen interpretive principles, of course. Right? There he brings some teaching from Rabbi Chaim on a fortiori reasoning. And he claims that an a fortiori argument is not at all a logical principle. It is a tradition from Sinai, and we use it in an entirely formal way—not logical but purely technical, mathematics. Why? He brings examples of this. He brings the example of the a fortiori argument of “the ninety,” “the princes carried ninety, all the more so by themselves”—some aggadic a fortiori argument; even there there is logic, he’s mistaken about that. But an example often brought in this context is Rabbi Chiya’s first teaching in Bava Metzia 3, that a person’s own admission should not be stronger than the testimony of witnesses, by an a fortiori argument. Meaning, if witnesses testify that you owe part of the sum, that obligates you in the oath of one who admits part of a claim, all the more so from your own admission. And there it seems very illogical. Never mind, I don’t want to get into it—one time I gave a lecture here on Saturday night at Beit Menachem. So that a fortiori argument looks very illogical. And that is always used as an example showing that the a fortiori argument is a formal principle. It is not ordinary human logic. That’s nonsense. Simply nonsense. It cannot be said. We see in many places that there is logic there, and where there is no logic, we do not make an a fortiori argument. If you don’t understand the logic, think a bit more. If you think a bit more, you’ll find the logic there. And I can show you the logic also in Rabbi Chiya’s first teaching—that was the subject of the lecture I gave then—and also in the a fortiori argument of “the ninety,” there is logic there. There is logic in everything. If there is no logic, you don’t make the a fortiori argument. As I said earlier too, in a case where there is a refutation to an a fortiori argument, but my logic tells me that the injured party’s courtyard is more similar to the public domain than to the moon, then they will make the a fortiori argument despite the refutation. Because logic says that it is similar.
[Speaker C] And that’s not a refutation.
[Rabbi Michael Abraham] Exactly. But logic determines that. It’s not formalism. If it were formalism, then the moment there is a refutation, the a fortiori argument falls. You don’t keep thinking after you’ve already done the analogical mechanics.
[Speaker I] So that really greatly reduces the weight of a refutation within an interpretive principle. Meaning, not only do I not begin without logic, but even when there is a refutation, sometimes I don’t stop.
[Rabbi Michael Abraham] Right, right. Everything is subject to logic. Now, as I showed earlier, logic alone may not have given me this. Meaning, if there were no tradition, maybe I wouldn’t use this logic, because really, who knows—in the injured party’s courtyard, can you infer from tooth and foot to horn or not? So the Torah says: you can make such inferences. Not to punish, but to infer—that you can do. That is why tradition is needed here. But the tradition—and I spoke about this at the beginning of the chapter, where he discussed the relation between logic and expositions—I said that exposition is not mechanics. It’s clear that exposition is a trigger that is followed by logic, or that logic accompanies it, even in verbal analogy. You find a word here and a word there—“under, under,” what we brought earlier, or “giving, giving,” what we brought earlier regarding payment of the best-quality land in damages. Obviously—okay, so these two passages have the same word. What do you do with that? In what respect are you comparing them? Does that now mean that in all damages everyone has to stand on one foot? In all damages—what? Everywhere? Or is it only with oxen because there too it is written only about an ox? In what respect do I make the comparison from this passage to that passage? In respect to what logic says should be compared. Always logic.
[Speaker J] So maybe you only need to come to the thirteen interpretive principles if you haven’t solved the matter through your ordinary logic, and then you say: I have no choice, I’m going to something formal, which also has to be logical, but that’s because I ran into—
[Rabbi Michael Abraham] No. Where there is a plain-sense interpretation, obviously, then you don’t need the interpretive principles; on the contrary, that is the plain sense. Exposition is always something that is not on the level of the plain sense. Even though it too has some logic, and I spoke about this—this double-layeredness between exposition and plain sense. But yes, there is logic in this too. Only here the logic really does require some trigger, which probably does need tradition. Now, in the principles I spoke about logical principles and textual principles. A fortiori reasoning and verbal analogy are the two examples he discusses here. A fortiori reasoning is a logical principle; verbal analogy is a textual principle. The textual principles are a textual trigger to make an exposition, and it also tells me in what direction to make that exposition—generalization, learning from an example—but what to do, why to generalize, or what to learn from the example, there is no hint. That is all the expositor, in the end. “You shall fear the Lord your God”—so the rule is that the word “et” comes to include. The well-known Ben Gurionian rule that “et” comes to include. Fine—include what? Maybe chairs? “You shall fear the Lord your God”—to include chairs, that they too are to be feared? The verse doesn’t say what to include. The expositor’s logic says it. Indeed, Shimon HaAmsuni got stuck, right? He would expound every “et” in the Torah until he reached “You shall fear the Lord your God.” Why? Because he said: what, am I supposed to compare something here to the Holy One, blessed be He? Impossible. There is nothing—what am I supposed to include? I can’t find anything with my logic. So he almost thought of abandoning the whole enterprise of inclusions from “et.” “Just as I received reward for expounding, so I will receive reward for refraining”—and leave it. Right? Because he found no logic. There isn’t any. It’s not technique. Then Rabbi Akiva came and said: there is a solution. What is that solution? That solution is not something logical that I would have done without the exposition. Without the exposition I would never have said that if one must fear the Holy One, blessed be He, then one must also fear Torah scholars—that is very far-fetched. So what is it? The exposition, the rule, the trigger says to me: there is an “et”; something must be included. First of all, that is given. Now I can look for what is most logical to include, or what is least illogical—doesn’t matter—to include, and that is what I include. But had I not had this rule saying that one must include something from “et,” I would not have derived the obligation to fear Torah scholars, or at least not necessarily. So there is a textual trigger from which the exposition emerges, but what we do with the exposition is always logic. And the same is true with the principles… that’s in the textual principles, where this is obvious. But even in the logical principles it is like that. That’s what we just saw with a fortiori reasoning, or with a paradigmatic analogy, which is analogy. Yes, a fortiori reasoning is also a kind of analogy, actually. So there too it is obvious that some logic is involved; it is not logical mechanics. Okay. So that is also what he writes here. He says that, for example, with the principle of a fortiori reasoning—let’s read the last paragraph in section 24, the last paragraph that deals with a fortiori reasoning. “There is much to analyze in the principle of a fortiori reasoning. An a fortiori argument is not simply a ‘how much more so,’” meaning it is not about two things, A and B, where the relation between them is that A contains B. He means the saying, “If there are two hundred zuz there is certainly one hundred.” “And if the law exists in B, then all the more so it exists in A,” like “if there are two hundred, then certainly one hundred.” If that were the case, then all the give-and-take in the Talmud concerning a fortiori arguments would be incomprehensible—not how severity creates the a fortiori argument, and not how a refutation contradicts it, because the refutation could not contradict it. Therefore the severities and leniencies are not a simple ‘if there are two hundred, then certainly one hundred.’” What I claim is that even in “if there are two hundred, then certainly one hundred,” a refutation can still refute. Fine. “Rather, an a fortiori argument is a particular way of learning Torah that Moses received at Sinai.” There is a weight of tradition here. Without the tradition, perhaps we would not do this, or at least not always do it. Meaning, you need some anchor that puts this in my toolbox, this a fortiori argument, that I am permitted to use it. “And it is that between two matters in the commandments of the Torah one can find a connection, but the similarity in their laws is not necessary; one creates an analogy between them. If the severity of one as compared with the other can teach about a similarity in the law that one seeks to learn, one uses it to create an a fortiori argument.” I think the wording here is not precise. Meaning, that would have been true of a paradigmatic analogy. In a paradigmatic analogy I make an analogy from one thing to another; there it is obvious that the two things have to be similar to each other. There is no hint in the Torah telling me when to make the analogy. Analogy comes entirely from me. Meaning, there is no textual hint here to make an exposition. The Torah states some law—for example, “If one man’s ox gores the ox of his fellow,” then one must pay. Fine? I say: a dog that bites also requires payment. How do I know? I make an analogy from ox to dog. Fine? Where is that written? Is there some textual hint? No. Therefore this is a logical principle, not a textual principle. But in a fortiori reasoning, there are three data points; it doesn’t say that one must make an a fortiori argument from them. There is no textual trigger telling me, from these three data points make an a fortiori argument. No—the logic says it. The Torah only gives the data, right? As opposed to the textual principles, where the Torah gives you the trigger for the exposition—not logic is the trigger there, but one form of writing or another form of writing is the trigger for the exposition. Fine? So in paradigmatic analogy he is right, that the similarity here is a similarity that we decide upon by our own reasoning, that A is similar to B. In a fortiori reasoning there is a rational dimension, but still, it is not exactly paradigmatic analogy; a fortiori reasoning is a different principle. Because the relation of severity does not point to similarity. The relation of severity does contain a certain dimension of inclusion—let’s call it that, inclusion with a soft edge. It’s not really inclusion; it’s not simply “if there are two hundred, then certainly one hundred,” but it’s also not merely a similarity between two things, with no preference of one over the other. It’s a strong similarity, a similarity with direction. In fact, if we want to translate a fortiori reasoning into paradigmatic analogy—into analogy—the correct way to do it is not to compare the data themselves, but to compare the axes of hierarchy. Let me show you how analogy—how a fortiori reasoning—is actually a simple analogy, not even more than an analogy. Let’s return to tooth and foot and horn. In the public domain I know that horn is more severe than tooth and foot. From here I derive the conclusion that horn is more severe than tooth and foot also in the injured party’s courtyard. And then I apply that to tooth and foot in the injured party’s courtyard and derive the conclusion. Here I made a full analogy. The comparison regarding the hierarchical relation is itself a comparison on the same level, not hierarchical. What am I saying? I’m saying that if the hierarchical relation exists in the public domain, then it exists also in the injured party’s courtyard. Here the comparison is on the same level; it’s not an a fortiori argument. It is that the same hierarchical relation that exists here also exists there. And that is what the refutation is about. Exactly—no, exactly—and that is what the refutation is about. Exactly. When you look at a fortiori reasoning this way, you see that it is really an analogy. So an a fortiori argument is really an analogy. Even though it seems as if in a fortiori reasoning there is some sort of push, some hierarchy—it’s not just a similarity between two things where neither has an advantage over the other. But in fact, when you look more deeply at an a fortiori argument, you see that it too is an analogy.
[Speaker D] But an a fortiori argument is a kind of “if there are two hundred, then certainly one hundred.”
[Rabbi Michael Abraham] Right, which is why I say: the Talmudic a fortiori argument. The Talmudic a fortiori argument is an analogy. Right. Okay, so that’s why I say that in my opinion the wording here is not entirely precise, but the principle itself is correct. “If all the components of the two matters point to the similarity, and one finds a refutation that may indicate that they are not similar”—what is the refutation? The refutation is exactly that there are two axes of comparison, and now you need to check whether the axis in the injured party’s courtyard resembles axis A or axis B. So it basically says there is no similarity between the axes, or at least no necessary similarity between them. “The a fortiori argument is refuted. This must be examined in each and every topic on its own merits, and one must see the logic in this way of learning.” And here this connects to what I said earlier. In other words, a fortiori reasoning really is logical. There is no such thing as a formal a fortiori argument; that’s nonsense, simply nonsense. It cannot be said. It’s part of that same—I don’t know—Brisker fiction, that people think the Sages were equipped with some mathematical system from which they could derive things absolutely, and we simply lost the algorithm, so now all we can do is cling to the Sages and see what they did. There is logic in it, and that logic can be understood. You have to work at it; we don’t fully understand it. Obviously part of it was lost to us because the tradition broke down on this issue, but there is logic behind it. Okay, so that’s it on a fortiori reasoning. Now he moves to verbal analogy. As stated, a fortiori reasoning is a logical principle; verbal analogy is a textual principle, fine? But as I said earlier, it’s obvious that there is a logical dimension here and there as well. Even in verbal analogy there is a logical dimension on two planes. First, in the question of what exactly I compare—I don’t transfer everything from one thing to another. So with regard to which laws do I make the comparison? Even though the rule is that there is no verbal analogy by halves, just as there is no juxtaposition by halves, it is obvious that there is no juxtaposition by halves only for things that are relevant. If something doesn’t seem similar to you, you don’t force it to be similar. If it is clear to you that there will be a difference here—there is the verbal analogy of “to her, to her” regarding a slave and a woman—so what, does that mean now that because for a slave too they write with an ayin, therefore we need to correct all the Torah scrolls? Obviously we do not make a verbal analogy for things that do not sound reasonable to us, that do not seem similar to us between the two contexts. So first of all there is a logical dimension in the question of what we do after there is a trigger to compare. But there is another dimension, and it is no less important—and he will also discuss it—and that is the dimension of choosing which two words to use for the verbal analogy. Before the question of what you do with the verbal analogy, there is the very decision to make a verbal analogy. Not every two similar words in the Torah are a trigger for verbal analogy, and that is an interesting question—why not? From what I once told—I don’t remember—there is a book by a Jew named Chernik, The Book of Verbal Analogy. It was published in Lod, by the institute there—Abrams, I think it was called, I don’t remember—and in the library there. He published a book on verbal analogy, and there he argues that the early verbal analogies are verbal analogies only on words that are unique in Scripture. He does a kind of archaeology there; he’s an academic researcher, so he reconstructs periods—meaning, which verbal analogies are early and which are later. He identifies this, for example, by the sages involved, their generation, and so on. He does a historical analysis of the matter and classifies the verbal analogies by periods. And he shows that the early verbal analogies are all analogies between two words that appear only in two places in Scripture. It’s not just any two similar words that we find and immediately make a verbal analogy. But interestingly, this develops later, and then they also make verbal analogies with two words that are not unique. So how can that be? What—if originally they really did it only with unique words, then what are we inventing? This brings me back to everything we discussed earlier: are the interpretive principles an invention or a development? Fine? I think it is a development. And the secret here is that when they take such two words, apparently—I’m saying this because I don’t have an explanation for every pair of words, and I also haven’t worked on it enough to examine it seriously—but in places where I did see it, there has to be a reason why I choose these two words and make a verbal analogy from them. True, they can appear in other places in the Torah. In the later verbal analogies this is also done between words that appear in other places in the Torah, but still, in these two places there is a reason why these words were chosen. It’s not just because there are two similar words here and that’s it. There is some kind of interpretive understanding of where this works. Now part of this is stated explicitly in the Talmud: whether the word is available for exposition. Available on both sides, available on one side—the Talmud compares and distinguishes between different verbal analogies. “Available” means that the word is superfluous. So what does that really mean? That in the early verbal analogies they took only two words that were unique. Well, that itself calls for interpretation—why exactly were those two words used in precisely those two contexts? Apparently in order to compare. But later sages say: fine, I can apply that same logic also to a word that appears elsewhere in Scripture, but in these two places it is available, it is superfluous. That too calls for interpretation. What difference does it make? It’s really the same idea. Therefore what I’m really doing is extending the logic of verbal analogy, but I’m extending it on the basis of the original logic; I’m not inventing it—it’s not an invention. It is the claim that I can apply the same logic to further cases. Fine? And therefore what this means is that in verbal analogy there has to be some reason why these words were chosen—especially when the words are not unique. If they are unique, maybe you don’t even need that, because that itself is a sufficient reason. But if the words are not unique, there has to be some reason. Now, the Talmud itself says this. It says that one makes a verbal analogy only when the words are available. If it is available on one side, then one does it, but a refutation can still overturn the verbal analogy—if there is a refutation. But if it is available on both sides, then there are no refutations either; then one simply makes the verbal analogy and that’s it—one makes the verbal analogy and there is no refutation against it. But there too you already see that the availability—the redundancy of the word—is actually the trigger for the exposition. It’s not just that you take two words; it’s not some mechanical thing. Rather, how do you know whether it is available or not? Logic. You look and see whether it adds something, or whether you can propose a wording in which that word is unnecessary and the verse would still tell you everything it says. That is interpretive logic. Now there can be a dispute about whether a given word is available or not—and there are such disputes. Is a certain word available or not? Whoever derives something from that word thinks it is not available. There are Talmudic discussions like that. So then what does he do—how can he make a verbal analogy if it is not available? This shows that the expositor’s logic, the expositor’s overall picture, affects the question of how you make a verbal analogy. Now this is especially interesting regarding verbal analogy, because verbal analogy is the principle about which the Talmud says that a person may not formulate it on his own unless he received it from his teacher. A person does not formulate it on his own. An a fortiori argument—a person does formulate on his own. A verbal analogy—a person does not formulate on his own unless he received it from his teacher. There is a dispute between Rashi and Tosafot about the other eleven principles. Are they like a fortiori reasoning or like verbal analogy? It is generally accepted to think that they are like a fortiori reasoning—that all the principles we do on our own except for verbal analogy. Verbal analogy is unique. But this is a dispute between Rashi and Tosafot. In any case, even verbal analogy, about which it is certainly said that a person does not do it on his own—even there we see that logic is involved. And there are disputes about it, and Nachmanides indeed comments on this—one moment—Nachmanides indeed comments on this because there are disputes about verbal analogy. Nachmanides and his students, several medieval authorities among his disciples, all write that it is not true that we received the whole thing from Sinai. Rather, it means that we received some hint from Sinai that here one should make a verbal analogy, or that we received the conclusion and the verbal analogy is merely a support for it, or that we received that these words are for verbal analogy but were not told what to do with them. There is some hint that is supposed to help us, and this connects to what I said earlier. Because really, without that, what—just compare any two words in the Torah? From that we could make a complete mess. The Sages never came close to doing that; it is clear that they did not. So how did they decide? The Talmud says they received by tradition what to do. But what does “by tradition” mean? It means they understood which word was superfluous and intended for verbal analogy. That fits the picture I described earlier. You do not need to say that there was really an explicit tradition: from these two words make a verbal analogy. Rather, they received a tradition of how to analyze the text and how to discover whether this word is superfluous or not superfluous. That is the traditional skill. It doesn’t mean exact details. Rather, they were skilled in textual analysis, to see whether these words were superfluous, available or not available, and accordingly they made a verbal analogy. That’s all.
[Speaker I] It’s not always necessarily true that the Talmud calls this “available,” but maybe that’s even a very late term. Just in general you see that even if the words aren’t superfluous syntactically, a certain phrasing can sound similar to something we saw elsewhere. But that doesn’t necessarily mean that the word is available in the literal sense. One hundred percent.
[Rabbi Michael Abraham] That’s exactly what I said earlier—that “available” isn’t really available. You need some trigger in the text to tell you that this word is intended for verbal analogy. It’s not enough that there are two identical words. “Availability” is only an expression that describes this. If it is superfluous, then that is a simple trigger. And obviously, if there is some understanding that these two passages are similar and you also see a key word that is similar in both places, that too is itself a kind of availability.
[Speaker G] That’s the direction. What do I mean? I think in a great many Talmudic passages, when you see the verbal analogy and afterward they try to convince you that the word is available or not available and propose all sorts of texts, it really doesn’t always pass.
[Speaker C] One hundred percent true.
[Speaker G] It looks like there was some logic, they looked for something that should work here. Some logic was missing, or some test case that needed to be handled. And the closest thing was a slave. Right. So they said, fine, let’s start with slave, and now they had to force the text so that there would be a word here and a word there.
[Rabbi Michael Abraham] “Force” I’m not sure about.
[Speaker G] Why? Because when you read the sentence, the forced wording of the verse—
[Rabbi Michael Abraham] Still, one has to be careful. We once talked about the difference between the holy tongue and our language. We’re prone to mistakes here. In fact, those who don’t know Hebrew are better at this. Those who do know Hebrew sometimes look at the formulations of the Sages and it seems unreasonable to them. But I think that sometimes, when you think in biblical terms, it can sound reasonable. We are simply prisoners of our language.
[Speaker G] They drop the heh, or they want it without the vav.
[Speaker I] It’s “ein” for them without a yod, not “ein” without a yod. Yes, what?
[Rabbi Michael Abraham] No, no—again, I didn’t say that in every place it’s like that. I said you have to be careful, though. By the way, there too, with “han” without a yod, I don’t know whether that “mehen” which is “han” without—
[Speaker I] Yod—the only instance the Talmud found was “mehen” in yevamish? That’s something else entirely.
[Rabbi Michael Abraham] All right, but it could be that in biblical language, as Hahn understood, that really is what it means. Why not? Whether this is the only example or not—fine, that doesn’t matter right now—but I’m saying we have to be careful with that. I don’t think that if the Sages forced an interpretation, then it was just arbitrary, so why did they do it? It wasn’t just… Clearly they had some reason why they decided to derive it from here. Because of the logic. Exactly. I definitely accept that broader understanding, and he’ll write that too: that it doesn’t have to be specifically a free expression in the simple sense of the term. On the contrary, a free expression is only one example of the fact that you’re not just taking two words and doing mechanics; rather, the text has to signal to you that some comparison is supposed to be made here. Sometimes it signals that by means of some extra word, sometimes you understand that the passages are similar, sometimes your logic tells you that the passages should be compared because the legal reasoning says they are similar—for all kinds of reasons, it doesn’t matter right now. So that, I think, is a broader meaning of the concept of a free expression, and I completely accept that. That is exactly what I wrote. Now, let’s read it in him now, because overall that’s more or less what he says, what I’ve been describing up to now. A gezerah shavah too is only between two similar subjects. That itself already says something. It’s not mechanics—taking two words and that’s it. Now, it has to be—no, you have to understand whether it’s really similar or not. If it’s not similar, then it’s not just logical mechanics. Usually, for each topic the Torah uses a different style, and if there is similarity in wording, that teaches similarity in content, when the subjects are close and can be compared to one another. Between subjects that are different and far apart from one another, you never find a gezerah shavah. Nor can just any two identical words be used for a gezerah shavah. If it says “et” here and “et” there, we won’t derive a gezerah shavah from that. Between connecting words there is never a gezerah shavah, because otherwise we would turn the whole Torah into one single law. By the way, I’m not completely sure about that; I haven’t checked it. But in places where there is some indication that a connecting word is extra, it could be that they would also make a gezerah shavah from a connecting word. I don’t think so—you need some logic or some indication that we’re supposed to make a gezerah shavah. I’m not sure that with connecting words it can’t happen. Clearly, to do it automatically on connecting words is madness. That would mean that all the occurrences of “et” in the Torah have to be the same. Obviously not. Okay, that much is clear. But I don’t think we need to go so far as to say there are no gezerot shavot based on connecting words. That’s too far. It needs to be checked; I haven’t checked it, but I don’t think it has to be that way. Because otherwise we would turn the whole Torah into one single law. A gezerah shavah is only where we notice that the Torah uses the same style in two places, in a way that can indicate a comparison between them. According to one opinion in the Talmud—see Niddah 22—a gezerah shavah is derived only when the expression is free. And that draws attention to it. According to another opinion, when it is not free, one may derive it but may also refute it; that is, if there is a challenge showing that not all components of the matters are similar, then we do not learn one from the other. And again, that raises the question: if it can be refuted, then where is the tradition? A person does not derive a gezerah shavah unless he received it from his rabbi. So how can you refute it? How can a gezerah shavah be refuted? We received it by tradition from Sinai, didn’t we? Fine, you could say that only in the case of a free expression is it tradition, because then you don’t refute it. But if it’s free, why do you need tradition? If it’s free, then you know it is to be derived. On the contrary, the tradition is needed דווקא where…
[Speaker E] Even in a tradition there can be cracks—something can get missed, or a mistake, or things like that—so you refute it. Apparently the tradition wasn’t correct.
[Rabbi Michael Abraham] Fine, but then what’s the point of the tradition? If the tradition itself is suspect as possibly incorrect, then what is it? Just one more support. Another support? It’s logical too and… okay. And there’s a distinction between free on one side and free on both sides. And even when we derive a gezerah shavah, we do not compare for every matter. Exactly what I said: these are the two planes. One plane is choosing the pair of words on which I make the gezerah shavah. I chose the two words; now the question is what to do with the gezerah shavah. Regarding which issue should we compare these two things? So logic enters there too. That means it enters on both planes. True, there is a rule that there is no gezerah shavah—however, Tosafot prove in several places that a gezerah shavah does not compare for every matter. Because the comparison should only be regarding things in which it is possible and appropriate to compare the two subjects. And in truth, with a gezerah shavah this is always a problem, because you want to compare two subjects, and you always say that at the starting point they are different from one another—so what is there to compare? Now if they are different, the question is which one do you take to which? Do you take the one that is obligated to the other one that is exempt and learn that the other one is obligated, or do you take the one that is exempt to the one that is obligated and learn that the obligated one is exempt? The Talmud asks that.
[Speaker G] That’s how the Talmud asks it. Why did you find reason to learn it this way? Why not learn it the other way around?
[Rabbi Michael Abraham] I don’t remember it asking that—maybe in certain cases—but generally it doesn’t ask that. There are places where this is also a dispute between Rashi and Tosafot—whether there is no half-gezerah shavah—or Rashbam and Tosafot, I think, it seems to me that it’s a dispute, where Rashbam claims there is no half-gezerah shavah—I think, if I remember correctly which one is Rashbam and which one is Tosafot—one of them claims that “there is no half-gezerah shavah” means that just as you learn from A to B, you also have to learn from B to A. And the other says that “there is no half-gezerah shavah” means that you take all of A to B, not just part of A to B. Now usually this dilemma doesn’t really exist. Because what happens when in one case there is obligation and in the other exemption—the one that is exempt is not exempt because I have a verse exempting it; rather, I simply don’t have a verse obligating it. So basically the law is open. True, if I don’t fill that in, it will remain exempt. But if I have a gezerah shavah from somewhere else where I have a source that there they are obligated, then obviously the direction is to take the obligation to the place of exemption, not the exemption to the place of obligation. If I have a special source that exempts there, then indeed the situation will be the reverse. All right? If there is a source exempting here and a source obligating there, then I simply won’t apply the gezerah shavah. All right? Therefore usually there is no dilemma about which direction to take the gezerah shavah. The direction is always from the known place to the exempt place. That is the… It is well known that a person does not derive a gezerah shavah on his own. Does that mean that gezerot shavot were transmitted to Moses at Sinai? Absolutely not. There are many disputes about gezerot shavot. That is Nachmanides’ argument that I mentioned. And if they had been received from the Holy One, blessed be He, or had been received from Moses our teacher who learned them, there would not have been dispute about them. Here I accept Yossi’s comment from earlier. This argument is very questionable. The fact that something is a law given to Moses at Sinai does not mean that dispute cannot arise about it, even though Maimonides writes that. And he explains some of them—he tries to explain—but in another part Maimonides gets stuck. This claim of Maimonides is problematic.
[Speaker G] He didn’t mean—Maimonides didn’t mean—that there was never dispute, as it were, about what is accepted as tradition, so about that they don’t argue. Isn’t that what he meant? There could be dispute. No—that if there was corruption along the way, then you’ll find a dispute about something that someone says is a law given to Moses at Sinai.
[Rabbi Michael Abraham] But if there is no corruption and everyone agrees, then of course there’s no dispute.
[Speaker G] That’s not—so what did he say?
[Rabbi Michael Abraham] No, that’s an empirical claim, not a normative one. According to your reading, what he says here is a normative statement—that one may not disagree with a law given to Moses at Sinai. Maimonides presents it as a factual claim: that regarding a law given to Moses at Sinai, no dispute ever arose. And that—that’s the claim. In the Talmud it does not say that one has to receive the gezerah shavah from Sinai; it only says that a person does not derive a gezerah shavah on his own. And Rashi adds: unless it was received and came from Sinai. So in Rashi, yes, he always says that. Rashi also says, “it is a learned tradition.” Rashi always adds: a law given to Moses at Sinai. For Rashi, “it is a learned tradition” means a law given to Moses at Sinai. The idea is that the question of when parallel style really comes to teach a comparison between subjects and when it does not is not so simple. Therefore, if a sage does not have a tradition of many generations in which everyone learned that such-and-such an expression, appearing in two places, indicates a comparison between them, he should not innovate such a derivation on his own. Because you need textual sensitivity to know whether these really are two words fit for a gezerah shavah or not. That is not Rashi’s plain meaning, of course. Rashi’s plain meaning is that it comes from Sinai. He wants to say that it means there must be a tradition established by authorized sages and so on. There is something like this in Kedmat HaEmek: the Netziv writes in the introduction to Haamek She’elah, and there he writes regarding “it is a learned tradition.” Rashi always says: a law given to Moses at Sinai. From Maimonides it sounds as though “it is a learned tradition” means some kind of ancient tradition, not necessarily a law given to Moses at Sinai. Therefore he really explains that there is a dispute between Rashi and Maimonides about what “it is a learned tradition” means. Similarly, that is what he wants to say here about a law given to Moses at Sinai itself, not about “it is a learned tradition.” And there the discussion is whether “it is a learned tradition” means a law given to Moses at Sinai. He claims—and Abu Dalia claims as well—that even “a law given to Moses at Sinai” is not literally a law given to Moses at Sinai, but only a tradition accepted from outstanding sages. He means with regard to gezerah shavah, not every law given to Moses at Sinai. Rather, when Rashi says that it has to come from Sinai, the meaning is that it has to come from an ancient tradition from authorized sages and so on. For example, the Talmud says regarding the twenty-four primary categories of damages: all are like primary categories in that payment is from the best property. What is the reason? It comes from the equivalence of “instead of,” “giving,” “he shall pay money.” Can we really be sure that the expressions “instead of,” “giving,” and so on all indicate a comparison regarding the manner of payment? That it specifically has to be from the best property? That it should be from the best, yes? In damage payments one has to pay from the best of his field and the best of his vineyard. And movable property is also called the best—it doesn’t matter. But not every type of payment is accepted; it has to be high-quality payment, readily marketable, right? So why do they decide that this comparison is specifically about the manner of payment? Maybe the comparison is about—I don’t know—something entirely different. It is not so simple. We would not rely on ourselves in such a matter. But if many generations of great sages, who knew the ways of the language, thought so—not necessarily from Moses at Sinai—then we can rely on them. And if we look carefully, we will understand that they are right, that it really does make sense that these expressions indicate the manner of payment. Therefore this gezerah shavah is in fact applied to the manner of payment. And here logic says so. And if we have lost that logic, then we need to rely on sages who still had that linguistic sensitivity to biblical language, and they knew how to identify those two words and derive them. And I think it would be very worthwhile—this is one of the conclusions that emerges from his approach, and I completely agree with him on this point—to revive a bit of that linguistic sensitivity and try to see how the Sages actually worked, and to see whether it might be possible to make additional gezerot shavot on our own. All right, we’ll stop here.
