In the 11th and 12th centuries, the center of gravity of Ashkenazi intellectual life was in northeastern France and the Rhineland, although it would gradually move eastward over the course of the subsequent centuries. But Rabbi Isaac ben Moses, who became one of the great medieval experts on Jewish law, was born around 1180 in the German frontier province of Bohemia, and later settled in Vienna—a city almost as distant from the Ashkenazi heartland. He is better known by the name of his major work Or Zaru’a, taken from the verse from the book of Psalms, “Light is sown for the righteous, and gladness for the upright in heart.” Tamar Marvin tells his story:

To its Jewish denizens, Bohemia was known by the unflattering moniker “the land of Canaan,” and so the Or Zaru’a terms his Slavic glosses l’shon Canaan, “the Canaanite language.” Bohemia was indeed something of a hinterland in the 12th century, with its best and brightest finding their way to Regensburg and Prague. It seems that Rabbi Isaac suffered from economic straits and possibly other misfortunates in his younger years; in any case, he was impelled to travel widely, his peregrinations taking him to a wide swathe of the medieval Ashkenazi world.

And it’s this that makes Rabbi Isaac such an important tradent of Ashkenazi traditions, [i.e.], one who is responsible for preserving and handing on the oral tradition. Isaac Or Zaru’a went everywhere, talked to everyone, and wrote it all down. Isaac sought his first teachers in Prague, [the Bohemian capital], and Regensburg [in nearby Bavaria], . . . and from there to Speyer, possibly Cologne, and Würzburg, followed by Paris and Coucy in France, acquiring teachers in each locale.

This unusually large and broad set of mentors gave Rabbi Isaac grounding in the full array of Ashkenazi learning. From the margins he burst onto the very center of cultural life. The fruit of these many wanderings and years of learning coalesced in Isaac’s magnum opus, the Or Zaru’a. It wasn’t just a belletristic (and comforting) name; Isaac had in him the touch of a poet.

Isaac’s most famous student, Meir of Rothenberg, is perhaps the premier figure in medieval Jewish jurisprudence, whose rulings have an enduring influence on contemporary practice.

In a recent episode of 60 Minutes, a former State Department official tells the interviewer that U.S. support for Israel following October 7 has “put a target on America’s back” in the Arab world “and beyond the Arab world.” The complaint is a familiar one: Middle Easterners hate the United States because of its closeness to the Jewish state. But this gets things exactly backward. Just look at the rhetoric of the Islamic Republic of Iran and its various Arab proxies: America is the “Great Satan” and Israel is but the “Little Satan.”

Why, then, does Iran see the U.S. as the world’s primary source of evil? The usual answer invokes the shah’s 1953 ouster of his prime minister, but the truth is that this wasn’t the subversion of democracy it’s usually made out to be, and the CIA’s role has been greatly exaggerated. Moreover, Ladan Boroumand points out,

the 1953 coup was welcomed by Ayatollah Ruhollah Khomeini, [the architect of the 1979 Islamic Revolution], and would not have succeeded without the active complicity of proponents of political Islam. And . . . the United States not only refrained from opposing the Islamic Revolution but inadvertently supported its emergence and empowered its agents. How then could . . . Ayatollah Khomeini’s virulent enmity toward the United States be explained or excused?

Khomeini’s animosity toward the shah and the United States traces back to 1963–64, when the shah initiated sweeping social reforms that included granting women the right to vote and to run for office and extending religious minorities’ political rights. These reforms prompted the pro-shah cleric of 1953 to become his vocal critic. It wasn’t the shah’s autocratic rule that incited Khomeini’s opposition, but rather the liberal nature of his autocratically implemented social reforms.

There is no need for particular interpretive skill to comprehend the substance of Khomeini’s message: as Satan, America embodies the temptation that seduces Iranian citizens into sin and falsehood. “Human rights” and “democracy” are America’s tools for luring sinful and deviant citizens into conspiring against the government of God established by the ayatollah.

Or, as George W. Bush put it, jihadists hate America because “they hate our freedoms.”
