I mainly meant the educational outcomes: the Muslim world produces scientists from within it (even if on a limited scale), whereas the Haredi world does not. What is the reason for this approach? Is the Haredi world “worse” than the Muslim world, and in what way, and what causes this?
I’m working from the assumption that religious fundamentalism (in almost all religions) does not reject modern achievements.

Again, you’re making a baseless generalization. Do you have data? Did you examine different Haredi and Muslim populations and see this phenomenon? Did you distinguish between fundamentalist Muslims and those who aren’t? After all, among Jews you don’t lump Haredim together with others.
As for your actual point, the Haredi world has produced quite a few scientists (in my unsubstantiated opinion, significantly more than the Muslim world). These are people who left it. Those who don’t leave simply don’t study science, so how would they become scientists? A prosaic and banal explanation, but what can you do? That’s the truth.
I’d suggest you examine how many soccer players came out of Haredi education versus Muslim education. I think here Muslims will have a clear advantage. And again, the deeper answer to the matter is that Haredim don’t play soccer.
I’ll conclude with a thought experiment: why do you find more wearers of Lithuanian-style hats and shtreimels among Haredim than among Muslims? After all, they’re equally fundamentalist.

Benjamin, what happened? Are you afraid to write “Haredim” without that double yod? “Hareidim”?! More righteous than the Pope… If it wasn’t intentional, then just take this as a note for next time. And as for the question itself, the Muslims didn’t experience a harsh exile, and that’s the crux of the matter. And the rest—go learn.

With God’s help, 18 Sivan 5779

As a proud Jewish fundamentalist, for whom the guidance of the sages of Israel in the Middle Ages [= our early rabbinic authorities; in my fundamentalist language 🙂 ] is a guiding light, I get the impression that the medieval sages were very familiar with the science of their time, both medicine and the natural sciences and also philosophy, and they grappled with the conclusions of the scientists of their day, accepting certain things and rejecting others. Of course, Maimonides was not like Nachmanides, and the sages of France and Ashkenaz were not like the sages of Spain and the Islamic lands. But there was awareness and engagement.

As for today’s Haredim, perhaps they are not fundamentalist enough 🙂 In any case, I’ve heard of a physicist named Rabbi Dr. Michael Abraham who studied for many years in the Haredi stronghold of Bnei Brak, who is highly accomplished in the sciences, and he is also extreme in his fundamentalism, in that he does not submit even to the medieval authorities (Rishonim), and only to the earlier layer, the Talmud, does he grant authority.

So we see that fundamentalism and science do not necessarily contradict one another.

Best regards, Shatz

One of the reasons adherents of Muslim fundamentalism engage in science is that science helps them develop the means of warfare that assist the commandment of jihad, a commandment that was dear to them as the heritage of their forefather Ishmael, who was blessed that “his hand would be against everyone, and everyone’s hand against him.” And even when they accepted the influence of Judaism and became somewhat more refined, the influence of their pre-Islamic heritage still remained significant.

On the other hand, among Jewish fundamentalists—even the Religious Zionists, who think we have returned to the restored independence of biblical and Hasmonean times—there is also a tendency to emphasize the “ways of pleasantness,” which according to King Solomon are among the ways of the Torah, and they look for various ways to wage holy war, where possible, through peaceful means whose influence is more effective. All the more so the Haredim, who are more committed to the Three Oaths that forbid provoking the nations (and according to the Achiezer, one must not provoke even the Jewish nation…)

In short, there are differences between fundamentalists according to the different foundations upon which their worldview is based.

Rabbi Michael Abraham is not Haredi, because in one of the videos he’s wearing a blue shirt, thereby violating two prohibitions:
1. “Let your garments always be white.”
.2. “Let him wear black and go to a place where he is not recognized and do what his heart desires!”

Regarding comment 1, about the blue shirt: one could appoint Rabbi Dr. Michael Abraham as Sephardic Chief Rabbi, a role by virtue of which he would wear a blue robe.

Regarding comment 2: “let him wear black” — one could appoint Rabbi Dr. Michael Abraham as a justice on the Supreme Court, and then by virtue of his office he could fulfill “let him wear black and wrap himself in black,” and most importantly: “do what his heart desires” 🙂

In short:
Let Rabbi Dr. Michael Abraham be appointed Sephardic Chief Rabbi, and also a member of the High Court of Justice, as Shatz recommends, and we will all rejoice and be glad.

In my opinion, broadly speaking, the Muslims are calling for war against the modern Western world and aspire to return to the Middle Ages, when they led the world.
You can see in all the terror organizations their feelings of inferiority vis-à-vis the Christian and Western world, and their aspiration to “conquer Rome and New York.”

The Haredim, by contrast, are not interested in war, but in separatism and detachment from the world.
This is not a new thing in Judaism, except that the Haredim as a movement arose as a reaction to the Enlightenment movement and oppose every kind of secular education, unlike earlier times, when despite the Jews’ separatism in exile, there was no opposition to general studies and engagement in science.
The combination of separatism and war against the Enlightenment created modern Haredism.

That is at least the ideological aspiration of the two groups. In practice, both the Haredim and the Muslims are divided within themselves regarding how to deal with the modern world and regarding integration into it.

Daniel,

In my opinion the comparison is incorrect. The Haredim are not able to fight like the Muslims; if they had the possibility, maybe they would do so.

The fact is that among the religious people (settlers) there are those who fight like the Muslims.

Boaz, you’ve really gone overboard.
