Summary
General Overview
The text develops a systematic way of thinking about halakhic probability, distinguishing between positive and negative forms of majority and doubt, and argues that many of the topics usually discussed are only properly understood when the uncertainty is negative and cannot be directly quantified. It then applies this framework to double doubt, explaining that when the uncertainty is negative, Jewish law often relies on formal structures such as “two doubts” or a “majority of sides,” whereas when the probabilities are explicit, the case should be decided according to the ordinary laws of majority rather than by formal labels. The speaker repeatedly emphasizes that Jewish law is the relation between facts and norms, and therefore when the factual circumstances change, the applicable ruling may also change without Jewish law itself having changed.
Majority, probabilistic multiplication, and two majorities
The speaker opens by reexamining two majorities in the context of permitting agunot, arguing that the real issue is the distinction between negative majority and positive majority. A positive majority is a case in which the percentage is known, so it makes no difference whether the majority was produced directly or by multiplying probabilities. A negative majority is a case in which there is no concrete number, and then Jewish law uses other criteria to determine whether the probability is decisive.
Jewish law, reality, and changing circumstances
The speaker argues that Jewish law is not simply the factual condition x or the norm y, but the relation between them. If the facts change, then the norm that applies to those facts may also change, and that is not considered a change in Jewish law, because halakhic reality is the relationship itself.
Customs, Orthodoxy, and Reform
The speaker continues with an extended discussion of custom as a dynamic cultural phenomenon. In his view, a custom often begins as a change and only later becomes fixed, so that “do not forsake your mother’s teaching” preserves a custom that was itself once an innovation. He distinguishes between Orthodox and Reform approaches, and says that many arguments identified with Reform are not inherently Reform at all, but rather legitimate halakhic arguments about a change in the relationship between facts and law.
Doubt, legal doubt, and double doubt
The speaker defines an ordinary halakhic doubt as a situation in which either the factual side or the legal side is unclear. He distinguishes between positive doubt and negative doubt, and explains that double doubt often arises from negative uncertainty. He applies this distinction to one piece versus one piece out of two pieces.
“I found an open entrance,” Tosafot, and the Rivash
The speaker turns to the passage in Ketubot 9a and explains that the Rivash proves that when the first doubt is negative, you cannot simply calculate percentages. He says that the whole framework of double doubt is designed for negative uncertainty, not for positive probability.
Majority of sides, double doubt, and Maimonides and Rashba
The speaker explains that according to Maimonides, Torah-level doubt requires stringency only by rabbinic law, and according to Rashba, the leniency of double doubt comes from a majority of sides. He stresses that a majority of sides is not a statistical majority but a formal halakhic count of sides.
Questions, responses, and conclusion
The final part consists of questions about customs, multiple synagogues, majority versus division among stores, and whether scientific claims in the Sages are mistaken. The speaker returns to the point that when the factual basis of a halakhic claim is wrong, the ruling may lapse.
Full Transcript
[Speaker A] Okay, let’s begin.
[Rabbi Michael Abraham] In the last few lectures I started dealing with what I called probabilistic multiplications, where the focus was really on the concept of two majorities that appears in the context of permitting agunot. It has a source in the Talmud in Ketubot, though in the end we saw that it’s not exactly a source for this whole issue of two majorities. But through that issue of two majorities, I presented a somewhat more systematic way of looking at this whole world of majority and doubt. We saw that ruba de-ruba is basically a structure of two consecutive branchings: there is one split into two possibilities, and the lower branch itself also splits into two possibilities, in principle both lower branches, and we saw various possibilities that come out of that. We distinguished between negative majority and positive majority. A negative majority is a situation where I know there is a majority against a minority, but I don’t have a quantitative measure of how large that majority is. And we saw that in the case of a negative majority, Jewish law sometimes tries to bypass the need for an explicit calculation. But when the majority is a positive majority, then there is really no significance to the difference between one majority and two majorities, because in the end the question is simply statistical. If I have a percentage majority, then it’s a majority; I don’t care whether that majority came from multiplication or came directly. The whole difference between a majority and ruba de-ruba exists only where the majority is a negative majority. And when the majority is negative, I don’t really have a number on the bottom line. And when I don’t have a number, then I try to suggest other criteria or other measures to make sure that I indeed have an overwhelming, absolute majority. We discussed this regarding permitting agunot, and I do that not through calculation but by requiring that there be a multiplication of two majorities. And this whole story exists only because we’re dealing with a negative majority; that is really the focal point of the whole matter. Meaning, this whole move of multiplication — and we’ll see later on as well — really hides behind it this very, very important distinction, and one that many students don’t know or don’t understand, maybe even Torah scholars and halakhic decisors, and I think it’s very important to put this in focus, because the entire discussion applies only when the majority is a negative majority. If the majority is a positive majority, it’s really uninteresting whether it’s one majority or two majorities — it makes no difference. In the end, just tell me the bottom line: do you have a number? The majority is 70%; I don’t care if it came through multiplication or directly. All these formal distinctions between multiplication and no multiplication are only relevant where I don’t have numbers. If I don’t have numbers, I try in indirect ways to make sure that the requirements are met. In permitting agunot, those are very high requirements, but in other places the requirements are not so high, and that we’ll see in the topic we’re beginning today. And today I want to talk about what is really the more fundamental topic, but I think now we can understand it better — and that is the topic of double doubt. Double doubt is basically one subsection of the laws of doubt in Jewish law, and I want to touch on it a bit, and we’ll see that behind it sits that same distinction that has accompanied us over the last few lectures as well, between negative doubt and positive doubt. So maybe I want to begin — רגע,
[Speaker A] I’ll start with defining the concept of doubt itself. So basically we have a situation — the basic situation in Jewish law even before doubt —
[Rabbi Michael Abraham] The basic situation in Jewish law is that I have a factual situation x, and the halakhic norm y applies to it. Okay? That’s an ordinary case in Jewish law, no doubts or anything. Jewish law tells me: in factual situation x, what you must do, or what you are forbidden to do, is y. Now, in other series — not in this series, but in others — I’ve already spoken more than once about the fact that in truth Jewish law is neither this nor that, but rather the line connecting y to x. Jewish law is really the relation between the facts and the norms that apply to them, and that has many implications, this understanding — and this too is something many people don’t understand — it has lots of implications, for example regarding changes in Jewish law. Yes? If we are in a situation different from the original x that the Talmud, or whatever authoritative source, was dealing with, then the result y can also be different, and that is not called a halakhic change, because Jewish law is not the x and not the y, but the relation between x and y. For example, if Jewish law says that there may not be two synagogues in one city — there’s a dispute between Abaye and Rava, but Maimonides rules like Abaye — because of “lo titgodedu,” there may not be two study halls or two synagogues in one city. Now today we know that in every city there are many synagogues, which is directly against the ruling of the Talmud, a Torah prohibition, and nobody is bothered by it in the slightest, to the point that people hardly even write about it. Meaning, it just doesn’t bother people at all. And what stands behind this — again, I won’t go into details, I’m only bringing it as an example — is that the factual situation, the x, has changed. Meaning, true, today too there are cities — you’re sitting in one city — but the meaning of the concept of city today is completely different. Once, the place where we lived had great significance; customs were local customs; children lived in the same place where their parents had lived; overall, place was stable, continuous, more or less fixed. Changing place was a dramatic change. Today, almost no child lives in the same place his parents lived. In the morning you’re in Tel Aviv, by afternoon you’re already in Europe or the United States or Australia or who knows where. Movement is very easy and available, and so somehow, without anyone noticing, the concept of place undergoes a metamorphosis. And now the fact that we’re in the same city is uninteresting, and we’ve shifted to speaking in ethnic terms, not geographic terms. Customs are not customs of the place, but customs of the community, of where we come from. That is the more stable thing today, because place is not really all that important. And therefore the great, famous tension in this matter was with Rabbi Ovadia, who argued that anyone who comes to the Land of Israel should follow Maran the Mechaber, the Shulchan Arukh, because this is Maran’s locale — the Shulchan Arukh was essentially the mara de-atra in the Land of Israel. And anyone who arrived here, even Ashkenazi communities, once they came here had to follow Sephardic custom, the custom of the Mechaber. Why? Because local custom is binding. Now Rabbi Ovadia is right. Originally, customs were local customs, not communal customs. The customs that determined practice were local customs. The only thing is that place lost its significance. The x that once existed — place — is different today, and because it is different, the law that applies to it, y — that you don’t make two synagogues in one city — also changes. Yes, you do make them. Why? What, did we change Jewish law? Are we Reform? Are we deviating from the accepted rules of Jewish law? No. Because the accepted rule in Jewish law is not that you don’t make two religious courts in one city, but that if you have a city whose meaning is such-and-such, then you don’t make two religious courts in it. That “if-then” relation is Jewish law. Not the x and not the y, but the relation —
[Speaker C] — is Jewish law.
[Rabbi Michael Abraham] And therefore, once the x changes, the y will also change in order to preserve the if-then. The if-then is preserved even though the x is different and the y is different. Meaning, Jewish law in essence is the arrow; it’s not the y and not the x. And many people make this mistake. Just today someone asked me by email or on the site, I don’t remember — I think by email — someone said to me: look, it says in the Shulchan Arukh that a person has to distance himself from women very, very much, and therefore, he explained, that’s why the Haredim are actually more attached to Jewish law, because they are very strict about distancing themselves from women. I wrote on the site that in my opinion Haredi modesty practices are a distorted hysteria. So he said to me: what? But it says in the Shulchan Arukh that a person has to distance himself from women very, very much. I told him exactly this point: the fact that something is written in the Shulchan Arukh is not itself a halakhic determination — that’s just guidance — but even if let’s say it were a halakhic determination, I do not see the bottom line, the y, as being Jewish law. The y is not Jewish law; the if-then is. Take today’s circumstances and compare them to the circumstances then. If today’s circumstances are different, then the Jewish law we apply to those circumstances must also be different. Because what we preserve is the if-then, not the x and not the y. The x changes because the world changes; consequently the y will also change, because what has to be preserved is the relation between x and y. The y by itself is not Jewish law. The relation is Jewish law. Fine. So I’ve spoken a lot about this when talking about changes in Jewish law and various things like that. But for our purposes, the structure —
[Speaker D] But sorry, with the Reform movement, the basic principle of what they rule is that the x’s are always changing. They work on the x’s. They don’t work on the x’s; x’s are facts. Someone who denies that facts change — no, no, they work on the relation. No, they work on the relation; they say the x is different now. You’re saying that then you need to change the y. So maybe they change the y in line with the x that they say has changed, and you wouldn’t change it, but the x itself really has changed, and then it’s already a matter of interpretation, what you infer from it.
[Rabbi Michael Abraham] I absolutely would change it, and I’m in favor of changing it. No, that’s not right. I think that if you preserve the relation between x and y, that is not Reform — that is Orthodoxy. And I wrote a series of columns — so where, where, where is the Reform? I’m explaining, I’m explaining. I wrote a series of columns about Modern Orthodoxy, and among other things I tried to explain the difference between that and Reform. And I explained there — I devoted an entire column in that series to explaining the difference between them and Reform — and what I said, briefly, so as not to leave the question open, is that many of the Reform arguments are not Reform arguments. They may be raised by Reform people, but the argument itself is a completely legitimate Orthodox halakhic argument. You can agree or disagree; it doesn’t mean I necessarily agree with it, but it is an entirely legitimate argument. There are disputes even within the Orthodox halakhic world. What distinguishes the Reform movement is that they also have arguments that are not like that. Meaning, they also have arguments that recommend changing the y without preserving the relation between x and y — and that is Reform. And there I gave examples, detailed examples, from a book by Moshe Zemer, who was the head of the Reform movement here in Israel, a book called “Sane Halakha.”
[Speaker A] It’s in the Rabbi’s lecture series too, on ethics and faith — it’s there.
[Rabbi Michael Abraham] I talked about it both in lectures and there are also columns on it; you can look there. In any case, for our purposes, what matters is that in that sense the Reform people are completely right, and in those senses often it is the Orthodox who distort Jewish law. Meaning, they are the ones who preserve the y even though the x has changed. You understand that they necessarily create a different relation between x and y. Because for a different x they take the same y, so that means they are actually the ones who damaged it — they carried out a reform in Jewish law. Meaning, the halakhic conservatives are making a reform in Jewish law, because what they changed is the relation between x and y. They preserved y, but since x changed, then de facto the connection between x and y changed — and that is Jewish law, that is what needs to be preserved. But this really belongs to that other series, where I elaborated on this at length, and I don’t want to get into it more here.
[Speaker A] Can I ask a question?
[Rabbi Michael Abraham] Okay, it’s on this topic, but —
[Speaker A] No, no, not on that topic — on the topic of custom. I just wanted to ask, very briefly, when does local custom determine things and when does communal custom determine things? I’ll explain my question a little: local custom here in the Land of Israel, for example, is supposedly the issue of putting on tefillin on Chol HaMoed, right? The communal custom of Ashkenazim and Yemenites and some Sephardim was to put them on, and that’s a custom that supposedly may not be changed.
[Rabbi Michael Abraham] What does “may not be changed” mean? You know, Rabbi Blumentzweig, may he live a long and healthy life, once said something correct. He said: we are very strict about the sanctity of customs. There’s even a story about the — who was it? I think about the Sha’agat Aryeh — who came to Königsberg. He was being pursued by all sorts of, no matter, innovators and renewers, and he came to Königsberg and asked them to bring him the community ledger. Yes, like the Ten Commandments… where all the customs were recorded and so on. And he wrote the Ten Commandments in it. And they asked him what that was about, and he said: I wish you were as strict about the Ten Commandments as you are about the customs of the community. Meaning, the sanctity of custom, that you don’t touch it, is true — “do not forsake your mother’s teaching” appears in the Talmud in Pesachim, in the chapter “A place where they have the custom” — but it has to be taken in proportion, because how is a custom created? A custom is usually created as a result of change, a change in status, right? Suddenly some new custom comes into being. Meaning that before it wasn’t there, and from the moment it comes into being, now it’s a custom. “Do not forsake your mother’s teaching” — now you’re not allowed to change it. Meaning, we freeze the change. Meaning, we zealously preserve from change something that was itself once a change.
[Speaker A] That’s what I was asking — this thing itself was a change, because up until the parents and the parents before them —
[Rabbi Michael Abraham] So I’m saying, I turn your question mark into an exclamation mark. And what I’m basically saying is: right, there was a change in customs here, but that’s perfectly fine. Now the custom that was created is a new custom, and that custom is now the binding custom. The fact that in previous generations, in my or your community, some custom was practiced — fine, that too was a change, and now that has also changed, and everything is fine. Custom is a dynamic thing.
[Speaker A] No, it wasn’t a change — it was a rabbinic determination, and also a halakhic ruling.
[Rabbi Michael Abraham] A rabbinic determination is already a different question, not so simple. But in any event, it was something that changed at some stage and became fixed, and now it becomes fixed again. So what’s the problem? Meaning, there are customs, and customs are dynamic. Just as they are created, so they can disappear. Yes, I’ve said more than once that there is a very amusing phenomenon: the study halls built on a very substantive, revolutionary innovation are usually the very ones that speak in the most zealous and fanatical way about the obligation to preserve the customs of our forefathers. Yes, take the Briskers, for example, on the one hand, who constantly talk about custom and tradition. Yes, tradition is perhaps the most common word in the Brisker outlook, which is ridiculous, because the whole Brisker approach is one big revolution against tradition. And likewise, yes, students of Rabbi Kook, same thing of course. Yes, the conservative students of Rabbi Kook. There are many students of Rabbi Kook of many kinds. But his conservative students constantly talk about tradition, and whom you apprenticed under, and who your rabbi was, as if they themselves were not born out of a vacuum. So very often this fanatical talk about the duty to preserve customs rests on someone who is himself sitting on top of a dramatic change, and often this is some kind of way, I don’t know, of denial or of coping with something you’re unable to look at honestly.
[Speaker F] Fine. Rabbi, if we were to formulate customs this way — what is custom, really? Custom is a cultural expression. And if we understand that culture is something very, very important, precisely because it is not done artificially but in the most natural way, it comes from, I don’t know, the deep layers of the people, then it is very important. On the other hand, to replace it lightly, to replace one culture with another, that really is contempt for all that was your ancestral heritage. And then we really understand the difference between Reform and modern conservatives, because if you respect culture and make changes in it because culture develops, but not in a way where you move entirely to —
[Rabbi Michael Abraham] That’s too general a statement. I don’t like such vague definitions. If you do a lot, if you do a little. I think you need to discuss a specific change, not how many changes you make.
[Speaker F] But here, for example, the classic example the Rabbi brought, that nobody discusses the problem that there are many synagogues with different liturgies, despite this being a clear Torah prohibition, is because it just developed naturally, without people thinking about it. And precisely because it developed without people thinking about it, good people, the people most faithful to the heritage of their ancestors, felt they needed to act this way, without thinking, without engaging in reflection.
[Rabbi Michael Abraham] The question of reflection is also discussed there in that series of columns; I agree. It’s not the only criterion, but it is certainly an important criterion. But I do still want to note something, which I also wrote there and elaborated on: I think you can examine a specific argument for change and ask whether it is Reform or not. Not a community, saying how many changes you made, and by the quantity of changes you made I decide whether you’re Reform or not. I claim there is a specific argument for change that can be examined to see whether it is Reform or not. Meaning, the criterion is not quantitative or statistical; there is a substantive criterion of content. But that really belongs in another series. Fine. In any case, for our purposes, that’s the ordinary situation in Jewish law. There is a factual situation, and a certain law applies to it. What happens in a case of doubt? In a case —
[Speaker G] Rabbi, sorry, I had a question.
[Rabbi Michael Abraham] What?
[Speaker G] I had a question — right, I once had a discussion about this. What happens when the x, the facts, don’t change, but our way of looking at them today is more precise and more correct than the way people saw them once? I once had some discussion about this, I don’t remember the subject, but Maimonides made some mathematical calculation —
[Rabbi Michael Abraham] I spoke about that there too. I think that where there is a mistake in grasping the facts — if the facts changed, that’s one discussion. If there was from the outset a mistake in understanding the facts, because they simply did not know the facts properly, then that halakhah lapses on its own. Meaning, nothing special is needed.
[Speaker G] No, it’s not that they made a mistake. It’s just that the calculation wasn’t precise. Today we have a more precise calculation.
[Rabbi Michael Abraham] So a question of precision in calculations is something else. I’m talking about a mistake. Questions of precision in calculations — okay, we never make calculations with complete precision anyway. So the question is how much precision to take into account; that’s already another issue.
[Speaker A] Yes exactly, and in what kind of case that is —
[Speaker G] So that’s a different discussion.
[Rabbi Michael Abraham] Another discussion; I won’t get into it here, it’s not relevant to us. Fine.
[Speaker A] Is mistake relevant in laws of concerns, Rabbi? Huh? Is mistake relevant in laws of concerns?
[Rabbi Michael Abraham] Also, doesn’t matter, in all sorts of areas.
[Speaker A] No, no, I mean specifically in relation to it. All laws of concerns, supposedly.
[Rabbi Michael Abraham] For example, some of the concerns, yes. Okay. But Rabbi —
[Speaker C] But Rabbi, also the forty days for the formation of the fetus, asking whether it is male or that it should be male?
[Rabbi Michael Abraham] That’s also a mistake? Right. So what’s the question?
[Speaker C] But here it’s seemingly for stringency — here it’s forbidden to ask at all, so then it comes out —
[Rabbi Michael Abraham] No, no. Fine. So I’ve spoken about that more than once. You know it already, no? I assume at least. It’s on the website, take a look. Fine. In any case, the point is that this is the ordinary halakhic situation. What happens in a state of doubt? In a state of doubt we have this diagram. This diagram is really just that previous diagram twice over. Right? A is one example of it and B is one example of it. What distinguishes A from B? I have two possible ways to understand either the factual state — I don’t know the facts, whether it’s A or B — but for each set of facts I have a known law. Fine? I just don’t know what the facts are. My doubt is about x. This is doubt in reality. There is doubt in the law, legal doubt, where I know what x is, but I don’t know what the arrow is, or what y belongs to x. Which y should be attached to this x? That is what is called legal doubt. In any case, I will represent doubt this way, where here it could be — you can write x here, fine? And then the doubt is doubt in the law, whether to attach kosher or non-kosher to it. And you can say that A and B are simply two interpretations of x, and accordingly the law for each interpretation is clear. But I don’t know which interpretation to give x. Therefore, for me, this is the picture of doubt, and I won’t get into the distinction between legal doubt and factual doubt from here on. I’m only saying: any such doubt can be either legal doubt or doubt in reality. At the moment I’m not entering into that distinction. What happens in a case of doubt? We know the rule: Torah-level doubt requires stringency; rabbinic-level doubt allows leniency. Maimonides’ view is that Torah-level doubt requiring stringency is a rabbinic law. Rashba and other medieval authorities hold that Torah-level doubt requiring stringency is itself Torah law. Okay? Those are the ordinary laws of doubt. Now, if I don’t know whether this is forbidden fat or permitted fat, then it’s a doubt about what x is. Fine? But if I know that it is forbidden fat, I just don’t know what the law of forbidden fat is, then that’s really a doubt in y. The x is given, and the doubt is a doubt in y. Now the rule generally in cases of doubt is that we have fifty-fifty. If it’s sixty-forty or eighty-twenty, then we’re in the area we discussed in the previous lectures. Then it’s really a case of majority, not of doubt at all. A case of doubt is when there is no majority in favor of A or B. I am in doubt, fifty-fifty. Okay? Of course the doubt can be positive or negative, as we’ll soon see. So in fact, doubt —
[Speaker F] Rabbi, doubt is really a state of cognition, right? Epistemological. It’s a feeling of the person, an emotion, a kind of awareness. Now let’s say a person has a halakhic doubt or a doubt in reality. You ask him: tell me, what do you think is more likely? He says, I don’t know, A seems to me 60 percent and B 40 percent. But I’m still in doubt. So would the Rabbi still count that as doubt, or is that already a majority?
[Rabbi Michael Abraham] No, that’s a majority. Majority is also doubt. It’s just doubt that isn’t fifty-fifty. It’s a majority.
[Speaker A] What about “most women are not aylonit”?
[Rabbi Michael Abraham] Doubt that isn’t a majority — doubt is when it’s fifty-fifty. When there is a majority, then the laws of majority apply; it doesn’t belong to the laws of doubt.
[Speaker A] No, that’s what I’m saying — we’re not discussing majority now.
[Rabbi Michael Abraham] Okay, right.
[Speaker F] No, I’m saying, even if it’s doubt in a person’s consciousness, in his halakhic judgment — let’s say it’s legal doubt. He says: I have a feeling that there is a 60 percent chance that law A is correct, but I’m not sure. The indicators of majority are known, but what should one rule? He says: I have a feeling that law A is the correct one.
[Rabbi Michael Abraham] No, that’s actually more difficult; here it’s harder to ground the claim that this is a majority and not doubt. In the case of stores, I have nine against one; I have some factual basis to determine that this is not evenly balanced doubt but that there is a majority here. In the case of law, the distinction between doubt and majority is an inclination of the heart. Now here there really is room to hesitate. In principle, in my opinion, if you have an inclination toward one side, then that is the law of majority. It is the law of majority because that’s the meaning of majority in the context of legal doubt. There are certainly many decisors and people who are afraid to rely on those inner inclinations. It’s hard for them to quantify it; I don’t know exactly what. And they treat every such thing as a state of doubt. So against that I’ve already written more than once, but yes, that’s a known fact.
[Speaker A] But a very well-known classic example of double doubt is with wine. A gentile who touched wine renders it forbidden, and here there is a doubt whether a gentile touched it at all. Okay, so that’s always fifty-fifty; there is no majority here. And then that creates a case of double doubt.
[Rabbi Michael Abraham] Who said fifty-fifty? You have a doubt whether he touched it or didn’t touch it — who said that’s fifty-fifty?
[Speaker A] It could be eighty-twenty. No, no. There in the passage about wine, whether a gentile touched it or didn’t touch it, right? So we don’t know — did he touch it or not? True, he went and brought wine.
[Rabbi Michael Abraham] And that’s called negative doubt. So that is exactly the difference between negative doubt and positive doubt. Positive doubt is when I know it’s fifty-fifty whether the gentile touched the wine or not. Fine? Say I have two people here, one of them a gentile and one of them a Jew. One of them touched the wine. Okay? That’s positive doubt. There is a 50 percent chance that a gentile touched the wine. Okay? There is a situation where I have one person, one piece — not one piece out of two pieces. I don’t know whether he is a gentile or a Jew and he touched the wine. Here too there would be room to say that it’s fifty-fifty, but if most of the people around are Jews, then no, it would be a majority.
[Speaker A] No, but in the double doubt of wine we’re talking about a gentile who brought wine, and it’s not known whether he touched it or didn’t touch it. Meaning, it’s a gentile, so it’s fifty-fifty.
[Rabbi Michael Abraham] It’s 100 percent a gentile.
[Speaker A] If it’s not known whether he touched it or —
[Rabbi Michael Abraham] Whether or not he touched it is not necessarily evenly balanced. Not knowing whether he touched it or not could mean there is an 80 percent chance he touched it, only you’re not sure. It could be that you know nothing at all, and then you treat it as fifty-fifty, and that’s called negative doubt.
[Speaker A] And the whole point is that this comes to permit, not to forbid.
[Rabbi Michael Abraham] It makes no difference whether it comes to permit or to forbid — that’s completely irrelevant. It doesn’t matter. The question is whether it’s eighty-twenty or fifty-fifty.
[Speaker A] If —
[Rabbi Michael Abraham] If you have certain indications that it’s more likely he touched it, then it’s not evenly balanced doubt. If you have no indications, then you don’t know that it’s fifty-fifty, but you assume that it’s a negative doubt of fifty-fifty.
[Speaker A] If I don’t assume that, then I’ve reached majority — that’s the whole problem. I don’t want to reach majority.
[Rabbi Michael Abraham] What do you mean, you don’t want to? The question is whether there is a majority or not. What does “I don’t want to” mean?
[Speaker A] No, if nobody knows —
[Rabbi Michael Abraham] Then there is no majority here. It doesn’t depend on your will; it depends on the facts.
[Speaker A] No, but in the facts there are no facts.
[Rabbi Michael Abraham] So if there are no facts and no indications, then that is what is called negative doubt, fifty-fifty. But it’s not really fifty-fifty — only because I have no way to decide in favor of one side, it is negative doubt, so I treat it as fifty-fifty. Remember I’ve brought you this example several times already? I have a fair coin and I toss it. Fine? What’s the chance it lands heads? Fifty percent. That’s positive doubt, because I know the coin is fair. So there is a 50 percent chance of heads, 50 percent tails. Now what if someone shows me a coin, and I have no information at all about this coin? I don’t know if it’s fair, unfair, how it’s built, I have no idea. If I had to bet, I would still bet fifty-fifty, heads or tails, right? But obviously it’s not really fifty percent. I have no information, I know nothing. That’s called negative doubt. I still treat it as fifty-fifty even though that’s not really the actual probability of fifty percent.
[Speaker A] Wait — so it comes out that every double doubt must be negative.
[Rabbi Michael Abraham] That’s where I’m heading in a moment, right. I’ll get to that in a moment.
[Speaker A] Fine.
[Speaker H] But in the case of meat pieces, even if the distribution is different we don’t give that significance, no? I didn’t understand. Meaning, even if I have three kosher stores and one non-kosher store, and the non-kosher store, say, is a huge supermarket —
[Rabbi Michael Abraham] That’s a completely different question. There are disputes among the decisors whether one takes into account the number of pieces in each store. But suppose there are four stores, more or less with the same number, and three are kosher and one is not kosher — then that is a majority, not doubt. Okay. Fine, in any —
[Speaker H] case, then in the case —
[Rabbi Michael Abraham] of doubt, in a case of doubt we basically go to stringency, whether the doubt is positive doubt or negative doubt. There was, on the site recently, some very long thread that in my opinion got completely tangled up, which discussed — wait — yes, among other things they discussed there the difference between one piece and one piece out of two pieces, what I mentioned earlier. If I have two pieces of meat, one kosher and one non-kosher, and I ate one of them and I don’t know which one — fine? That’s called doubt of one piece out of two pieces. If I have one piece and I don’t know whether it is forbidden fat or permitted fat, or kosher meat or non-kosher meat, and I ate it — that too is called doubt. Both are considered by Jewish law as doubt, meaning Jewish law views them as fifty-fifty. But there is a difference between them. Doubt of one piece out of two pieces is a case where the prohibition was established in place, and one brings a provisional guilt offering for it. In the case of one piece, one does not bring a provisional guilt offering. Now many times — and that was the claim in that thread — what is the difference? In both cases it’s 50 percent. That’s a complete misunderstanding. It’s simply not true. There is a statistical difference between the cases. It’s not a non-statistical difference; it’s a statistical difference. In the case of one piece out of two pieces, I have a positive 50 percent. For that one brings a provisional guilt offering. In the case of one piece, halakhically I view it as fifty-fifty, but it is not really a 50 percent chance that I ate something non-kosher. I have no way to determine what the percentages are, and therefore one does not bring a provisional guilt offering, because you don’t even know whether you are in a real doubt at all. True, from the standpoint of whether it is permitted or forbidden to eat, there is no difference: in both cases, Torah-level doubt requires stringency. But with respect to the provisional guilt offering, you do see a reflection of this distinction. Meaning, there is both a halakhic and a statistical difference between the case of one piece and the case of one piece out of two pieces, and the difference is that one piece is negative doubt, while one piece out of two pieces is positive doubt. In one piece out of two pieces there really is a 50 percent chance that you ate the kosher one or the non-kosher one, whichever. In one piece, it’s negative doubt: you do not know what percentage is kosher or not kosher, but since you have two sides and you don’t know how to weigh them, you treat it as evenly balanced doubt, fifty-fifty. Not that there is really a 50 percent chance you ate a kosher or non-kosher piece.
[Speaker H] Meaning, if hypothetically it really were positive doubt in a case of one piece? Yes, yes, exactly.
[Rabbi Michael Abraham] Then in principle one should have to bring a provisional guilt offering. I’m saying, this is a point that many people — including many later authorities, in my opinion — miss, this difference that today we’ll see the Shev Shma’tata did not miss: the difference between negative doubt and positive doubt. It’s a very important distinction. Now let’s take a look for a moment — fine,
[Speaker E] I —
[Speaker A] to double doubt —
[Speaker E] In just a moment I’ll get there.
[Rabbi Michael Abraham] I want to show you the Shev Shma’tata for a moment.
[Speaker I] Shma’tata of the Geonim? What? Of the Geonim?
[Rabbi Michael Abraham] No, no, Shev Shma’tata, by the Ketzot. The Shma’tata says as follows. You know what, let’s begin with the Talmud. We’ll start with the Talmud. Rabbi Elazar said — yes, you can see here below — Rabbi Elazar said, Ketubot 8b: “One who says, ‘I found an open entrance,’ is believed to forbid her to him.” Okay, meaning a man had relations with his wife for the first time on the first night and found an open entrance, meaning she was not a virgin. There are various discussions there, both regarding forbidding her to him and regarding the marriage settlement — if she is not a virgin, then only one hundred zuz; if she is a virgin, then two hundred. So Rabbi Elazar says he is believed to forbid her to himself. He comes to the religious court and claims, “I found an open entrance,” and he is believed. The Talmud asks: but why? It is a double doubt. Why is he believed? He should not have been believed. Maybe it happened after she married him and maybe it happened before; and even if you say it happened after she married him, maybe it was by coercion and maybe by consent. Maybe by coercion, maybe by consent.
[Speaker A] There is a double doubt here. Why?
[Rabbi Michael Abraham] It could be that she had relations even before she was betrothed to him, not while she was under him, or that she had relations after the betrothal. That’s one doubt. And if you say it was while she was under him, even then, if she had relations after the betrothal and therefore should become forbidden, there is still a doubt whether it was by coercion or willingly. If it was by coercion, she still does not become forbidden. A doubt whether willingly. So notice, let’s go down for a moment to the diagram. Never mind, not this specific case, but this is the diagram. Right, a doubt whether while under him or not while under him. If not while under him, then she is completely permitted. We’re talking here. A doubt whether while under him or not while under him. If it was not while under him, then it doesn’t matter whether it was by coercion or willingly—in both cases she is permitted, right? If it was while under him, then it depends. If by coercion, then she is permitted, and if willingly, then she is not permitted. Alright? So this structure of a tree with two branchings is basically the structure of a double doubt. Okay? The structure of a double doubt. Except what? Here, ignore for a moment the bottom rows—in an ordinary double doubt, she is basically permitted, permitted, permitted, and forbidden. Meaning, in one out of the four endpoints she is forbidden, and in three out of the four endpoints she is permitted. Okay? That is the diagram of a double doubt. I go back to the Talmud. Right, the Talmud asks: but this is a double doubt. Either she was under him or not under him—that’s one doubt. And even if she was under him, in which case she ought to become forbidden, there is another doubt whether it was by coercion or willingly. So this is a double doubt. What happens when there is a double doubt? If it was not under him, whether by coercion or willingly she is permitted. If it was under him, then if by coercion she is permitted, if willingly she is forbidden. So three out of four possibilities are that she is permitted, and one that she is forbidden. So when a person comes and says, “I found an open entrance,” even if we believe him that he found an open entrance, still three out of four possibilities are that she did not become forbidden to him. So why does Rabbi Elazar say that he is believed to forbid her to him? It’s a double doubt. The Talmud gives two answers. It is necessary only in the case of a priest’s wife.
[Speaker C] What happens
[Speaker A] with a priest’s wife?
[Rabbi Michael Abraham] A priest’s wife becomes forbidden even if it was by coercion. So there is a doubt whether it was under him or not under him, because if not under him she did not become forbidden, but if under him then she did become forbidden. And the doubt whether it was by coercion or willingly does not exist, because with a priest’s wife, whether by coercion or willingly, she is forbidden. Okay? Notice, this basically means that the diagram—I’m going back here—the diagram is this diagram, but with a priest’s wife what happens is this: if it was under him, then whether by coercion or willingly she becomes forbidden to him in both cases. If it was not under him, whether by coercion or willingly she does not become forbidden to him. So there are two possibilities in which she did not become forbidden and two possibilities in which she did become forbidden, which is a case of a single doubt, right? It’s not three out of four possibilities, but two out of four. It is basically one out of two. If it was under him, then she becomes forbidden; if not under him, then she does not become forbidden. There is no difference between coercion and willingness. Coercion and willingness are irrelevant. If you insist that it is still a tree with two branchings, I don’t care, but the endpoints of the tree are two against two and not one against three. So this is called one doubt and not a double doubt, and therefore he is believed to forbid her to him, because a Torah-level doubt is treated stringently. That is one answer of the Talmud. The second answer of the Talmud: and if you wish, say it is a Jewish wife, for example where her father accepted betrothal for her when she was less than three years and one day old. The second answer: we are talking about the wife of an ordinary Jew, not a priest, but her father accepted betrothal on her behalf when she was under three years old by a week, or whatever, under a day. Okay? What happens in such a case? There is a doubt whether it was by coercion or willingly. Okay? If by coercion then she is permitted, because this is the wife of an ordinary Jew. If willingly, then she is forbidden. But the doubt whether under him or not under him does not exist. Why does it not exist? Because if it were not under him, then she had relations when she was very young, under three, and under three her virginity returns. Meaning, it would already have healed, and when he came to her he would not discover an open entrance. Therefore it cannot be that this happened before the betrothal; it happened afterward. Okay, and therefore here too there is only one doubt. So these are two cases in which the situation is not a double doubt but a single doubt, so says the Talmud. Now Tosafot asks: “And if you say there is still a double doubt—perhaps by coercion, perhaps willingly; and if you say willingly, perhaps when she was a minor, and the seduction of a minor is coercion, as we say in ‘one who has relations with his yevama.’” What is Tosafot saying? You tell me we are dealing with the wife of an ordinary Jew whose father accepted betrothal for her when she was under three. So what? Then there is no doubt that it was not under him, or no doubt whether it was under him or not under him. So Tosafot says: yes, but there is a doubt—because even if it was under him, seduction of a minor is coercion. Therefore even if he seduced the minor supposedly willingly, the willingness of a minor is not willingness; it is coercion. So there is still a double doubt. There is a doubt whether under him or not under him, and even if under him, it could be that it happened when she was a minor, and the seduction of a minor is coercion. Tosafot says: “And one can say, there coercion is one thing,” and we’ll get to that later. Tosafot is basically saying in his answer: there, coercion is one thing. What does that mean? Seduction of a minor is coercion, but it is still coercion. There are two possibilities here: either it was coercion or it was willingly. The coercion—either he really forced her, or he acted with her consent but the seduction of a minor is also coercion. What difference does it make to me? This way it’s coercion and that way it’s coercion. There are many kinds of coercion, so it is still only one doubt: whether it was by coercion or willingly, that’s all. But we’ll get back to this answer later.
[Speaker J] And Tosafot says here, by the way, apropos of mistakes in facts: when the Talmud claims that before age three virginity returns, is that actually factually correct?
[Rabbi Michael Abraham] Fine, I wrote about that too—there is the well-known Shakh. Clearly it is not factually correct, in the sense of a sharp line at age three. Presumably, if I understand correctly—I didn’t ask, but I assume the intention is that it’s around age three.
[Speaker J] But is there such a thing as virginity returning?
[Rabbi Michael Abraham] Yes, that’s what the Talmud says. I haven’t checked that it doesn’t. Do you know otherwise?
[Speaker J] No, I don’t know, and I also don’t want to know. But again, theoretically, I’m saying the Talmud is now basing its entire argument on a fact that I don’t know is true at all, and I don’t know how they knew it was true.
[Speaker F] It really is a question how they knew. What, did they run an experiment?
[Rabbi Michael Abraham] I have no idea how they knew, but that was their claim. Tosafot continues and says: “And if you say—let us establish her in the presumption of being permitted to her husband?” Let’s place her under the presumption that she is permitted to her husband.
[Speaker E] Right, so even if it’s just one doubt
[Rabbi Michael Abraham] basically she should be permitted to her husband. So Tosafot says: “And one can say that coercion has publicity, as we say in the Jerusalem Talmud: coercion has a public rumor. And now that there is no rumor, willing relations are the majority and coercion is the minority, and majority plus presumption—the majority is stronger.” What is Tosafot saying? It’s somewhat similar to what we saw with two majorities. He says that when coercion happens, word gets out, and when a girl is assaulted, word gets out. Now here we did not hear any report circulating about this girl, so there is a majority. Meaning, the possibilities of coercion and willingness are not balanced. This is not an even doubt. It is unlikely that it was coercion, because if it were coercion, word would get out. And if we did not hear any report, then most likely it was willingly and not by coercion.
[Speaker J] What does it mean, word gets out?
[Rabbi Michael Abraham] Word gets out—the public knows she was assaulted. So Tosafot says that therefore this doubt of willingness versus coercion is not an even doubt. There is a majority in favor of willingness, and therefore she is forbidden.
[Speaker H] So because of that, now, that’s why we don’t establish her in the presumption of being permitted? I didn’t understand. That’s why we don’t establish her in the presumption of being permitted.
[Rabbi Michael Abraham] Yes, that’s why we don’t establish her in the presumption of being permitted, because there is a majority that it was willingly.
[Speaker H] So what is the significance of this coercion? Do you treat it as an ordinary doubt?
[Rabbi Michael Abraham] As what do you treat it? As one doubt, and one doubt is treated stringently. After all, Tosafot says we are talking about the wife of an ordinary Jew who is a minor, right? You’re talking about the wife of an ordinary Jew who is a minor. The wife of an ordinary Jew who is a minor leaves us with one doubt, right? Because there is no under him and not under him—it was certainly under him. Okay? Right. Just the doubt of coercion versus willingness. And therefore Rabbi Elazar was not accepted, alright? Tosafot asks: but establish her in the presumption of being permitted and also accept what he says, “I found an open entrance.” Tosafot says no, you cannot establish her in the presumption of being permitted with one doubt, because this is not just a doubt—there is a majority. “Join the minority to the presumption and it becomes half and half.” The minority joins… what?
[Speaker H] Meaning this is a weak doubt. It is a doubt, but not such a good one, basically.
[Rabbi Michael Abraham] A rabbinic doubt—Tosafot says that later—but right now it’s even a majority, alright? There is a majority in favor of willingness. So in any case we do not establish her retroactively in the presumption of being permitted, and this remains an even doubt, and in an even doubt Rabbi Elazar does not believe him regarding “I found an open entrance” to forbid her. Now the Shev Shema’teta comes and says as follows: “And I saw in the responsa of Rivash, section 352, and this is his language: I also saw what I wrote to our teacher Rabbi Nissim on the topic of ‘I found an open entrance,’ and what you asked on Tosafot—that on the contrary, we should say: join the minority of coercion to the half that was not under him, and then ‘under him willingly’ is a minority.” What does that mean? We have a doubt whether coercion or willingness, but the possibility of coercion is considered balanced, right? Meaning the possibility of coercion plus the presumption is considered balanced against willingness. Okay? That is one doubt. And join the minority of coercion to the half that was not under him. He is basically saying this: if it was under him—we are now talking about an adult woman, not a minor; we went back to a double doubt—so Tosafot says there is a doubt whether under him or not under him, right? A doubt whether under him or not under him, and on the side that it was under him, there is a doubt whether coercion or willingness. But coercion is a minority, right? So the minority of coercion together with the half that was not under him creates a majority, right? If it was not under him she is permitted, and if under him then although there is a majority that it was willingly, there is still a minority of coercion, right? The minority of coercion joins the half of not under him, and together they create a majority. “Under him willingly” becomes a minority. Is what I’m saying clear?
[Speaker H] Again, I’ll go back a side. Did the Rabbi just explain the double doubt here simply? What? This is the Talmud’s double doubt, basically?
[Rabbi Michael Abraham] He says that with a double doubt you can go leniently. What does that mean? He says like this: we have a doubt whether under him and a doubt whether not under him, okay? If not under him, then she is permitted, right? If under him—then it depends whether by coercion or willingly. Now coercion is a minority because coercion has publicity, right? So here basically there is a majority—this is not an even doubt, right? There is a majority that it was willingly and a minority that it was by coercion.
[Speaker H] Okay. Or toward prohibition, yes.
[Rabbi Michael Abraham] Exactly. So overall, what do I have? I have fifty percent that it was not under him, which means permitted. I have another ten percent here, which is a minority out of the remaining fifty percent—ten percent that is also permitted—and forty percent that is forbidden. So true, forty against ten is a majority, but that ten joins the fifty here, and overall there is sixty in favor of permission. So in such a case, even when there is a majority toward prohibition here, on the other side I have another doubt, so I do not need a double doubt in order to permit; a doubt plus a majority is enough. Do you understand what I’m saying? Usually we want a double doubt in order to permit, right? But here it’s stronger—double doubt is seventy-five percent, okay? Right? If not under him, she is permitted; if under him, then there is twenty-five percent permitted and twenty-five percent forbidden. Overall there is seventy-five percent that she is permitted—that is double doubt. Now what happens if the other side is not an even doubt but a majority? A doubt whether not under him, if so she is permitted—that is fifty percent. If under him, then it depends whether coercion or willingness. But coercion and willingness are not an even doubt, right? We saw in Tosafot that there is a majority in favor of willingness. Let’s say eighty percent in favor of willingness. Okay? Now that should seemingly make her forbidden, because double doubt permits, but a doubt plus a majority is not good enough; it’s weaker than double doubt, right? Tosafot says—Rivash, who objects to Tosafot, says—what are you talking about? That too should be permitted. You don’t need a double doubt. Even a doubt followed by a majority should be permitted. Why? Because in practice there is sixty percent in favor of permission.
[Speaker E] The minority of coercion joins
[Rabbi Michael Abraham] the fifty percent that was not under him, and in practice there is over fifty percent in favor of permission. So why do you need specifically a double doubt? It is enough to have a doubt followed even by a majority toward prohibition, and it should also be permitted.
[Speaker H] Meaning, a double doubt basically is not better than a majority. What? A double doubt is equivalent, not better than a majority.
[Rabbi Michael Abraham] What kind of reasoning is that? After all, a double doubt is no more than a majority. That is the assumption of the question here. A double doubt is just a majority. So even if the second doubt is not balanced, I still have a majority here in favor of permission. The second doubt need not also be balanced. The second doubt can involve a majority toward prohibition, because still in the bottom line I have a majority in favor of permission. So what is the problem? Alright? That is how Rivash asks on Tosafot. And he proves that this is said according to all the Tannaim—leave it, I’m not going into it now. So he says like this—and this is still the quotation of Rivash—“However, that is there, where half are males and half are females certainly and necessarily, for thus the King, King of the universe, established it.” I think in Bekhorot there it speaks about an animal that gave birth, and we want to know whether this is a firstborn donkey that goes to the priest or not. Now there is a known fact: this animal had milk before. And there is a rule saying that animals that have milk are animals that most likely have already given birth. An animal doesn’t have milk if it didn’t give birth, okay? Now if it has given birth, that basically means that the newborn now is not the firstborn donkey, because there was already one before it—it is not the firstborn, right?
[Speaker A] There is the same topic also with the cow of a gentile. Wait, wait, this is complicated enough.
[Rabbi Michael Abraham] Yes. So in short, if this animal had milk, then most likely it had already given birth, and this offspring is not the first offspring, right? But it could be that what she bore previously was a miscarriage, and it could be that what she bore was female and not male. So there are two possibilities here. So there too, basically, you have a case of doubt plus majority, and not double doubt but doubt plus majority. And about that he says: “However, that is there, where half are males and half are females certainly and necessarily, for thus the King, King of the universe, established it for the continuation of the species. The Holy One, blessed be He, established a rule in the world that the distribution of males and females is fifty-fifty. Therefore necessarily the males born from pregnancies are a minority—a minority, since miscarriages are a minority, and there is no way around this from any angle.” Right—if she gave birth to a male, what is the chance that she gave birth to a male before? There is a minority chance that she miscarried, right? Sorry, there is a minority that she miscarried, and among the possibilities that she did not miscarry there is a doubt whether male or female, right? So altogether he says they can be joined, and we do not worry about the minority of males. So Rivash says—sorry, not the Shev Shema’teta—that there indeed we say this. Why? Because the balanced doubt between males and females is a fifty-fifty doubt. And we know that; it is the nature of the world. And besides that there is also a minority of miscarriages. So there is basically a majority chance that this offspring is actually a first offspring. But here we do not say that women who have illicit relations are half under their husbands and half not under their husbands, such that we should say: join the minority to the half and permit her, for from where do we know that this is half and half? How do we know that among those who have relations, whether it was under him or not under him, it is fifty-fifty? We assume that it is a doubt. Who told you it is a balanced doubt? How do you know? So Rivash says: “Rather, we say the matter is in doubt, that this is possible just like that.” We have two possibilities—either under him or not under him. We have no information. We do not know, unlike the doubt of males and females where we have positive information—that it is fifty females and fifty males. Under him or not under him is a negative doubt—I’m already using my own terminology, right? We say that the matter is in doubt, that this is possible just like that. Alright? And now he continues: “And even if we say: join the minority of coercion to the possibility of not under him, still ‘under him willingly’ would not thereby certainly become a minority.” But we still say that one possibility is like the other. What is he saying? He is basically—the only one I have seen at least—making an explicit distinction between a positive doubt and a negative doubt. That is Rivash, and afterward the Shev Shema’teta develops it more. He is basically saying this: when my doubt is a positive doubt, then even if the doubt that follows it is a majority toward prohibition, I add the minority toward permission to the positive doubt and I have sixty percent permission. So I follow the majority. But if the doubt is a negative doubt—whether under him or not under him—and even if under him there is some chance that it was by coercion, a small chance, twenty percent. But still there is a chance it was by coercion. So let’s join those twenty percent out of the fifty, which is ten percent, to the fifty percent that it was not under him, and there is sixty percent that she is permitted. Rivash says no. Because here it is a negative doubt. In a negative doubt you do not really know that it is fifty-fifty whether it was under him or not, right? It could actually be eighty-twenty. Since you do not know, negatively you determine that we treat it as fifty-fifty. But that is merely a negative determination. You do not really know. Therefore if you ask me statistically—statistically—when, say, it is mostly under him, the doubt of under him or not under him—let’s say actually under him is twenty percent… oh sorry, twenty percent, okay? Can you show it on the diagram?
[Speaker E] Yes, one second.
[Rabbi Michael Abraham] Look, let’s say we are now talking about under him and not under him. Alright? That is one doubt. And even if under him, there is coercion twenty percent and willingness eighty percent. Alright? So seemingly in this fifty percent she is permitted, and out of this fifty percent another twenty percent—meaning ten percent—she is permitted, and forty percent she is forbidden. So she is permitted in ten plus fifty, meaning sixty percent against forty. So she ought to be permitted. Rivash says no. Why not? Because the doubt whether under him or not under him, the upper doubt, is a negative doubt. In principle it could be that only twenty percent is sitting here and eighty percent is there. The opposite could also be true—I don’t know. And think what happens if here it is twenty percent. Then I basically have twenty percent that she is permitted, plus… eighty percent that she is forbidden, of which twenty percent by coercion is sixteen percent—twenty percent out of eighty. Sixteen plus twenty is thirty-six percent that she is permitted, and sixty-four that she is forbidden. So you have no certainty that there is a majority for permission here, because the doubt is a negative doubt. If the doubt were a positive doubt, then no matter what the majority was, I would know for certain that there is a majority for permission here. Rivash says: with a positive doubt, if the second part is a majority, that is enough to permit, even if it is a majority—there is no need for it to be a balanced doubt. Even if it is a majority toward prohibition, yes? It will still be permitted. But with a negative doubt, I need the second doubt also to be a balanced doubt. Negative too—I don’t care—but balanced. But if it is a majority toward prohibition, I will not attach it to a negative doubt, because in the bottom line in terms of numbers it could come out as a majority toward prohibition. You do not have certainty here that you have a majority for permission.
[Speaker F] But why would a balanced doubt be enough?
[Rabbi Michael Abraham] Ah, so you can ask: even with a balanced doubt it could also be like that. So I say: that is exactly the same thing as the two-majority cases we saw in the previous lesson. Right, I have here a balanced doubt negatively, and maybe in truth it is eighty-twenty and not fifty-fifty. But there is no end to it, because almost all our doubts are like that. So what do we do? We create a formal rule that says: look, if you have a double doubt, and both doubts are balanced, then fine—even if they are negative doubts. Then you can assume it is seventy-five percent. Just as with one doubt you basically assume it is a doubt and you do not prohibit it with certainty, even though it could be eighty-twenty, because I assume that a negative doubt is fifty-fifty. A double doubt is a rule; double doubt is a rule that basically comes to bypass the need for calculation. Or in other words, if you have a calculation, if you have a calculation, there is no need to get to double doubt—do the calculation and see. If you have a majority for permission, permit it. All the rules of double doubt are rules stated only in negative cases. But there, if the situation is negative, then the second doubt must also be a doubt; it cannot be a majority, neither a negative majority nor a positive majority—it cannot be a majority toward prohibition. It needs to be at least a doubt, or a majority toward permission—then of course that is also fine.
[Speaker A] Meaning a negative double doubt is always toward prohibition?
[Rabbi Michael Abraham] No, no, exactly the opposite. A double doubt is always lenient, even if the doubt is negative. Where will this make a difference—wait, wait—where will this make a difference, that the doubt is negative? In a place where the first doubt is a negative doubt and after it comes a majority toward prohibition. In such a case, if the doubt were positive, then count the bottom rows: the bottom rows come out as a majority for permission. Right? Because there is fifty percent permission, and out of the fifty percent prohibition there are still some percentages for permission—just a few percent are enough to join the fifty and make permission.
[Speaker A] That’s what I asked—if in double doubt the first doubt has to be negative, then it works for us as double doubt even in the negative case, and if the first doubt is positive, then even if below it is negative, that also works as positive? No, no—
[Rabbi Michael Abraham] No, I was talking about the opposite, exactly. I’m talking about the first doubt. The first doubt is a balanced fifty-fifty doubt, and under the prohibiting branch there is a split that is a majority toward prohibition, okay? So if the upper doubt were a positive doubt—
[Speaker A] then
[Rabbi Michael Abraham] we simply do the probability calculation, so that’s fifty percent for permission and fifty percent for prohibition, from which there are another ten percent for permission, so in practice there is sixty percent for permission. Once there is a calculation there is no formalism—sixty percent for permission, you have a majority for permission, you are permitted. But if the first doubt is a negative doubt, then you have no calculations. That is where the formalism comes in. If the second doubt is a doubt, even if it is negative, then you are allowed to go leniently even though in truth you may be mistaken. But if both doubts are negative doubts and yet they are doubts, not majorities, then one may go leniently. But if the first doubt is negative and the second is a majority toward prohibition, then you do not join the minority for permission with the fifty percent permission over there, because there is no fifty percent permission there; it is fifty percent negative, not positive. In such a situation, we do not permit. That’s what I asked, Rabbi. I
[Speaker A] said that in the case
[Rabbi Michael Abraham] And if the first doubt—it doesn’t matter. If that’s what you meant, then we agree; no point making this more complicated.
[Speaker H] Fine, so it comes out in the conclusion too that basically a double doubt, when balanced, is basically like a majority, there is no difference.
[Rabbi Michael Abraham] A doubt—no, a positive double doubt is like a majority, that is the conclusion. The whole concept of double doubt does not deal with positive doubts. If they were positive doubts, I am not interested in double doubt or any structure at all—just give me the bottom line. If there is a majority for permission, go with permission; what do I care whether it is double doubt or not? Right? In the end, suppose there is a double doubt where both are positively balanced, okay? Then I have a calculation of seventy-five percent for permission and twenty-five percent for prohibition. So that is permitted not because of the law of double doubt, but because of the law of majority—there is seventy-five percent for permission. And therefore… therefore the claim is that even if it is fifty-fifty and afterward there is a majority toward prohibition—which from the standpoint of the law of double doubt does not help—but from the standpoint of majority law that is fine, because it gives me a majority for permission. And once the majority is positive, it operates by the laws of majority, not by the laws of double doubt. And under the laws of majority you can permit even if the second is a majority toward prohibition.
[Speaker H] I understand. Meaning, a majority of a majority is already another stage, as it were? Right, it is basically certainty.
[Rabbi Michael Abraham] A majority of a majority is what we discussed in previous lessons, and we already saw the same phenomenon there.
[Speaker H] And that is just greater certainty, as it were? It’s simply a higher probability? Right. But it is always on the same probability scale? Exactly. Regardless of the question of the “sides,” because many people talk about sides in double doubt.
[Rabbi Michael Abraham] Wait, wait, I’ll get to sides in a moment—no, soon, we’ll get there, I’m already getting to sides. So that is a very important point.
[Speaker E] And that is what the Shev Shema’teta basically
[Rabbi Michael Abraham] says, after he finishes quoting Rivash. Here: “Rivash has enlightened our eyes, that there is room to discuss this in terms of majority: for even if the sides are not balanced, the minority joins the half and becomes a majority. And this is specifically where it is known from the nature of the world that it is half and half; then even the minority can join to make a majority. But where it is not from the nature of the world, but merely that this is possible like that”—a negative doubt—“then we discuss it in terms of double doubt, and we require that both doubts be equal and balanced.” If the first doubt is a negative doubt, the next junction must also be a doubt and not a majority toward prohibition. A majority toward prohibition will not work. It needs to be a doubt, or of course a majority toward permission, then there is no problem. Because the calculation of the… You cannot make the probability calculation. And if you cannot make the probability calculation, then we have the formalism: doubt stringently, double doubt leniently. When we have probability calculations, when we are dealing with positive doubts, then we do the calculations; there are no laws. The laws are irrelevant. Suddenly doubt, double doubt—just give me the probability calculation, and that’s it. We follow the majority. So here I found maybe the clearest expression of this distinction between positive majority and negative majority, and it is a distinction that is at the root of all these topics. And so many people miss it, which is why I am dwelling on it, because it is very important to understand this. Now I want to discuss for a moment, with the time I have left, what the law of double doubt actually is. People ask: if a Torah-level doubt is treated stringently, why does a double doubt go leniently? Already among the later authorities, and already among the medieval authorities, they ask this. Now just from the question itself, notice. What is the question? I don’t understand. An ordinary doubt is fifty-fifty, so we go stringently. A double doubt is a majority for permission, so we go leniently. What is the question? The moment you ask the question, and look for an explanation why with a double doubt we go leniently, it is clear that you are talking about a negative doubt. Then you have no probability calculation. And then basically the question is: one doubt and a double doubt are both situations of doubt, and you do not know how to make the probability calculation. You have two sides—either it is forbidden or it is permitted—and you have two sides that are both possible, so you are supposed to treat them as fifty-fifty. So why, why do you go leniently with a double doubt? Do you understand that this whole question of the medieval and later authorities rests only on the assumption that the doubts are negative doubts? Because with a positive doubt there is no room for the question why one is lenient with double doubt. One is lenient with double doubt because it is by the law of majority. There is seventy-five percent for permission, and there is no need for the law of double doubt; there is the law of majority—“incline after the majority.”
[Speaker F] And what really is the answer to their question in a negative majority case?
[Rabbi Michael Abraham] Wait, we’ll get there, slowly. I’m saying the question itself shows that we are talking about a negative doubt. A positive doubt is not a law of double doubt at all; it is a law of majority. And many later authorities are mistaken in this, because they think double doubt operates by statistical majority. That is incorrect. Double doubt is in negative majority, and in negative majority there is no statistical majority, as the Shev Shema’teta and Rivash are saying now. So what is it, then? Why does it nevertheless work on a negative doubt? There are two main approaches among the medieval authorities. In Maimonides’ view, many explained—Rashba already explains it, I think—that Maimonides says a Torah-level doubt treated stringently is a rabbinic law. So if I have a double doubt, then I have a doubt whether to be stringent rabbinically; that is a rabbinic-level doubt, so we go leniently. Again, this is a formal rule. We have no probability calculation. If we had a probability calculation, the whole discussion would not begin. But if we do not have a probability calculation, then we are talking about formal rules. So with one negative doubt, the rule is that one goes stringently on the rabbinic level. If on top of that there is another doubt—right, whether under him or not under him—then rabbinically we go stringently. But even on the side that it was under him there is a doubt whether by coercion or willingly, so I have a doubt whether there is an obligation to be stringent rabbinically. That is a rabbinic doubt, so one may go leniently. That is Maimonides’ view. Rashba himself says—he holds that a Torah-level doubt is treated stringently by Torah law. So he cannot explain that double doubt is a rabbinic doubt. According to him it is a Torah-level doubt, not a rabbinic one. So why indeed do we go leniently with a double doubt? Rashba says: it is by the law of a majority of sides. Rashba says this in Bedek HaBayit. He says it is by the law of a majority of sides. There are three sides for permission and one side for prohibition, so there is a majority of sides here. Many people mistakenly think this means a statistical majority. It does not. A majority of sides is not a probabilistic majority; it is a majority of sides. There is a side—three sides for… say, whether under him or not under him, and if under him, whether by coercion or willingly. So let’s count sides. What are the sides for prohibition? If it was under him willingly, right? That is a side for prohibition. If it was under him by coercion, that is permission; not under him willingly, permission; not under him by coercion, also permission. Three sides for permission, one side for prohibition—we follow the majority of sides. This is not the law of majority; it is the law of double doubt. Many people ask Rashba: why do you need the law of double doubt? After all, we already have the law of majority. That is a mistake. Because the law of majority applies only to positive doubts. With negative doubts you do not have a majority here; you do not know how to do the calculation. The novelty of the law of double doubt is that even by counting sides you can follow the majority.
[Speaker F] Why?
[Rabbi Michael Abraham] It is a rule, a formal law, like the law that a Torah-level doubt is treated stringently. With a majority of sides one may go leniently.
[Speaker F] What is the logic of that?
[Rabbi Michael Abraham] The logic is that you see it as though there were a majority here, just as with negative sides you see it as though it were fifty-fifty. So here there are four negative sides, three against one, and you see it as though it were a majority. Same thing.
[Speaker A] It comes out that according to Rashba, there is no such thing as double doubt at all; there is only either majority or…
[Rabbi Michael Abraham] Double doubt is another kind of majority—it is a majority of sides.
[Speaker A] Right, so for him double doubt is…
[Rabbi Michael Abraham] But many people are mistaken because they say, “So wait, according to Rashba why do you need the law of double doubt? We already have the law of majority.” No, it is not the ordinary law of majority. The ordinary law of majority is when you have a majority and can tell me that it is more than fifty percent.
[Speaker A] Meaning in a double
[Rabbi Michael Abraham] doubt where both doubts are negative, you cannot tell me that it is over fifty percent. It is not at all certain, as Rivash said. It is a law of the Torah that we follow a majority of sides, and that too is considered a majority. That is the law of double doubt: that a majority of sides is also a majority.
[Speaker H] But can I look at it—can I apply the law of a majority of sides also in a case where I know it is a positive doubt? You can, but it is unnecessary, because it is already permitted to me by the law of majority, because
[Rabbi Michael Abraham] you already have a statistical majority, so by the law of majority you are lenient.
[Speaker H] But I saw that they discuss, for example, “we do not follow the majority in monetary law,” but maybe in double doubt we would?
[Rabbi Michael Abraham] It depends what kind of double doubt it is—negative, positive—we need to see the case.
[Speaker H] But if in monetary law you do not follow the majority, then there is no chance that with double doubt, in the best-case scenario, you only get to majority—you don’t go beyond it, even according to what the Rabbi is saying now.
[Rabbi Michael Abraham] Right, it could be that the law of
[Speaker H] double doubt was also innovated in monetary law. Why not?
[Rabbi Michael Abraham] No, what I’m saying is that if double doubt at most reaches the law of majority…
[Speaker H] No, what do you mean “at most reaches”?
[Rabbi Michael Abraham] It is like majority, but it is the law of double doubt.
[Speaker F] It is a different law from the laws of majority. He said that a majority of sides is like a majority, but it comes from the laws of double doubt, not from the laws of majority. It is a different law.
[Rabbi Michael Abraham] Whether it was said regarding money or
[Speaker F] no, that’s a separate discussion. Meaning, maybe we say “majority of sides,” but not because of the statistical claim, as it were—not because most likely that is the case. Right, rather this law of double doubt, that we follow a majority of sides, was said also in monetary law. Rabbi, but still, if it’s a formal rule and it’s not a law given to Moses at Sinai, these are human beings who sat and thought about it and said it was reasonable. Reasonable, just with Torah-level implications—fine, so what? So that means what determines things is not reality, but what we feel. We really feel that the majority is… you understand, it’s not a matter of statistical calculation.
[Rabbi Michael Abraham] I’ll translate what you call “we feel” into “intuition,” and we’ll come back again to the same side. Alright friends, we’ll stop here. If there are comments or questions, you can ask.
[Speaker A] By the way, apropos of the supposed mistake of the sages in the Talmud about the cow giving birth—in Bekhorot it says that the sages determined that a cow does not give birth until age three. There, in the case of a gentile’s cow, which is transferred for firstborn issues. So? Nowadays at thirteen or fourteen months it already gives birth freely.
[Rabbi Michael Abraham] Okay—either nature changed or the species changed.
[Speaker A] No, no, it depends on weight, the weight of the cow. Today it reaches three hundred and fifty kilos.
[Rabbi Michael Abraham] I think that this knowledge was reasonably available to them, because this is not some new knowledge—any cattle herder can tell you that. So I don’t know; either nature changed, or there was some such large majority, or I don’t know exactly. Fine, but it doesn’t concern us. Mistakes of the sages are not our topic. There were mistakes—obviously there were mistakes.
[Speaker H] Okay, anyone else? Yes, Rabbi, regarding what I asked at the beginning—this was with several stores, let’s say, where the distribution is such that one store puts out more pieces of meat. Suppose there are three stores, and one store is huge, so if you really sum the probabilities, it is like a majority against the sides. So is there a possibility that we would actually rule according to the sides even though it is against the majority? Or not?
[Rabbi Michael Abraham] So I’m saying, this is a dispute among later authorities. There are many later authorities who follow the larger store and not the number of stores, so they apparently understand that we follow the distribution. But I already explained that in the law of stores and in the law of an available majority, it is not really a statistical majority. The number of stores does not really determine the probability. The question is how it got lost, the thickness of the bags in each store, and all sorts of things like that, so it is by no means certain that it is connected to probability. I understand. Rabbi, I just wanted… But Rabbi Shimon Shkop, when he says that an available majority is not probability, there he speaks—and I’ll discuss this at the beginning of the next lesson—there he speaks about a majority of sides. He claims that with an available majority, what was innovated there is the idea of a majority of sides. Because basically each store casts a side onto the piece of meat. That is nine sides for permission and one side for prohibition—not because of probability but because I don’t know the source, which is negative, so I count sides and follow the majority of sides. And therefore I said that whoever said earlier—I think it was Shmuel—said earlier that double doubt or majority of sides we derive from logic and not from a verse, and I said I’m not sure. I’m willing to assume that, but not sure, because it could be that an available majority is the source, and for an available majority they bring a source from a verse from the court.
[Speaker H] Thank you very much.
[Speaker A] Wait Rabbi, I want to go back a bit to the double doubt of a gentile regarding wine: whether he touched it or did not touch it, and if there’s a doubt whether a gentile even opened the barrel. Is that positive or negative?
[Rabbi Michael Abraham] Completely negative, as you are describing it.
[Speaker A] No, that’s an example they bring as a standard double doubt. It depends on the circumstances.
[Rabbi Michael Abraham] If you know—if you have information about the quantities of people around here, that there are fifty percent gentiles and fifty percent Jews, then the doubt whether it was a gentile or a Jew is a positive doubt, and the doubt whether he touched it or did not touch it is a negative doubt.
[Speaker A] Right, so here you have one positive and one negative. Right, so because of that it will be permitted, because it joins with the positive, double doubt.
[Rabbi Michael Abraham] Even two negative doubts are a double doubt and are permitted, so certainly if one is positive and one is negative it will be permitted. The negative one only makes a practical difference if the other is a majority toward prohibition. Okay, fine.
[Speaker A] Okay, good.
[Rabbi Michael Abraham] Thank you very much.
[Speaker F] Rabbi, do you have the energy for a question from the fruit series, or is that a bit…
[Rabbi Michael Abraham] Of course, yes, please.
[Speaker F] I listened to the Rabbi’s lectures at Bar-Ilan over the past few weeks, so one thing the Rabbi talked about there, for example, was this paradox: whether God can make a stone that He can’t lift. So the Rabbi said that this is meaningless babbling. As if—you haven’t actually asked any question. Explain the question, and then I’ll answer. But for example, when the Rabbi talks about free will, the question of foreknowledge and choice, then the Rabbi said yes, God can limit Himself and not know what I’m going to choose. Meaning, if God wants and says, I don’t want to know…
[Rabbi Michael Abraham] I said exactly that I do not agree with that explanation. After all, my words are written in the series “The Perplexed” on foreknowledge and choice—I reject that completely. I brought the Or HaChayim on Genesis chapter 6, where he writes that the Holy One, blessed be He, denied Himself the possibility of knowing, and I said that this solves nothing. Okay.
[Speaker F] One more small question, Rabbi. When the Rabbi also spoke—he also talked about this in the weekly series… at Bar-Ilan from last Saturday night—about this issue of his debate with David Enoch, and then he added things in supplements and so on. So the Rabbi always told us that the prescriptivity of the moral or normative command is part of the whole point. That if a person says, yes, I know it says “Do not murder,” but why not murder? then you haven’t understood what “Do not murder” means. Right.
[Rabbi Michael Abraham] Yes, but here, in this week’s series, I know that it says to him “Do not murder,” and I ask myself why not murder—that’s not a problem at all, because he did not know that what is written is binding. But if I understand that there is a binding moral command not to murder, then there is no question of why not murder.
[Speaker F] So in order to know the “Do not murder,” that also means knowing the prescriptivity of the command, right? So why, when the Rabbi says that morality is—he presented it as logic, as something
[Rabbi Michael Abraham] That belongs to all logic?
[Speaker F] So if it exists and God
[Rabbi Michael Abraham] Let’s say were not obligatory—he already asked me this on the website and I answered him. I’ll tell you briefly. The claim is that a person who reaches the conclusion that there is a binding morality cannot ask himself, wait, but why obey it? But the fact that you reached the conclusion that there is a binding morality means that behind it sits a belief in God. Because without belief in God, you cannot hold the position that there is a binding morality. Why? Because without God there is no binding morality.
[Speaker F] That’s really something—after all, the Rabbi doesn’t know something about God that maybe—well, I don’t claim to—but I have the feeling that the Rabbi doesn’t know something about God that I don’t know, or that David Enoch doesn’t know. And yet David Enoch is committed to the moral command, and the Rabbi is also committed. So what is the Rabbi saying—no, because I know something about God?
[Rabbi Michael Abraham] No, the claim is that he is mistaken; he believes.
[Speaker F] But what does he know about God? After all, both of them, both the Rabbi and David Enoch, don’t know something about God that I also don’t know.
[Rabbi Michael Abraham] I know that He makes the moral command binding because I hold the view that the command is binding.
[Speaker F] But if we remove the moral issue from the matter, what do we know about God? That at most He created the universe. That’s the maximum we know about Him. And that doesn’t obligate me in anything; that’s completely the classic is-ought gap.
[Rabbi Michael Abraham] Why should I care whether you think that His being the Creator is enough to make Him binding or not? I think so; you can decide whatever you want.
[Speaker F] But that’s a fact—it’s completely a classic naturalistic fallacy. What does that have to do with anything? How does the fact that He created a world obligate me? The world is so hard and incomprehensible, and on the contrary, if the world by itself were anything, it would be a reason not to obey.
[Rabbi Michael Abraham] So what? Excuse me? Because I am obligated to the One from whom I came.
[Speaker F] And who said it was good for me that He created me?
[Rabbi Michael Abraham] I didn’t say it was good. It’s gratitude.
[Speaker F] On the contrary, in some sense He is to blame for bringing me into the world.
[Rabbi Michael Abraham] He is to blame for the fact that He
[Speaker F] brought me
[Rabbi Michael Abraham] into the world—and that doesn’t mean I don’t have to obey. Gratitude is a moral obligation. Not because He did me good. “It would have been preferable for a person not to have been created than to have been created”—they debated and concluded that. That’s it.
[Speaker F] No, so
[Rabbi Michael Abraham] I wrote in my article about philosophic gratitude. It is not based on gratitude in the usual ethical sense. It is metaphysical gratitude. If I came from His power, then what He wants obligates me. Why? I came from Him, and I am very upset that He created me. Because I am from Him. He—I, my whole being—is only because of Him.
[Speaker F] And it’s a shame I’m here.
[Rabbi Michael Abraham] Fine. If you do not accept that reasoning, then you do not accept that reasoning.
[Speaker F] Okay. No, I’m trying to understand it.
[Rabbi Michael Abraham] No, it is a basic reasoning. I do not know how to ground it in prior principles. It seems self-evident to me, but it is a basic reasoning. Okay, thank you very much. Sabbath peace, good night.
[Speaker C] Thank you very much.
