Itzhak ben Shlomo (c. 832-932) was born to a religious Jewish family in Egypt. He became renowned as the greatest physician in the country, and in 904 was hired by Prince Ziyadat Allah III. Several years later, he became court physician to Caliph Al-Mahdi Billah of the Fatimid Dynasty, based in Kairouan, Tunisia. Recognizing his immense wisdom, the Caliph made Itzhak (known in Arabic as “Abu Yaqub Ishaq ibn Suleiman al-Israili”, and in Europe as “Isaac Judaeus”) his leading advisor and tutor. Itzhak wrote numerous medical, astronomical, and mathematical treatises which transformed the scientific knowledge of the day. For instance, he is the first person in history to mention performing a tracheostomy. His works were widely distributed for centuries afterwards, and made up much of the medical curriculum of the Middle Ages. Itzhak was also a great philosopher, kabbalist, and mystic. He fused together Greek Neoplatonism with traditional Jewish mysticism, paving the way for the forthcoming explosion of Kabbalistic texts and Jewish mystical circles. His main disciple, Dunash ibn Tamim, wrote a profound commentary on Sefer Yetzirah, the most ancient of Kabbalistic texts. In addition to inspiring many rabbis, he was studied and quoted by great non-Jewish scholars like Thomas Aquinas and Roger Bacon. Among his many other writings is a deeply philosophical commentary on Genesis. In his day, Isaac Judaeus was the world’s leading sage, doctor, and scientist, and Arabic texts of the time refer to him as “master of the seven sciences” and “more valuable than gems”.

We do not have to accept theories as certainties, no matter how widely accepted, for they are like blossoms that fade. Very soon science will be developed further and all of today’s new theories will be derided and scorned and the well-respected wisdom of our day will seem small-minded.

Jew of the Week: Rabbi Yosef Karo

Code of Jewish Law

Yosef ben Ephraim Karo (1488-1575) was born in Toledo, then in the Spanish kingdom of Castile. The infamous 1492 Spanish Expulsion of the Jews took place when he was just four years old. The family first fled to Portugal, and were then expelled from there as well in 1497. They eventually settled in Nikopolis, in the Ottoman Empire, which had opened its doors to Sephardic Jewish refugees. (The Ottoman Sultan at the time, Bayezid II, reportedly said: “They tell me that Ferdinand of Spain is a wise man, but he is a fool, for he takes his treasure and sends it all to me.”) Karo was tutored by his rabbi father and soon became a rabbi himself. He also studied under the great Rabbi Yosef Taitazak in Salonica. For a couple of years, he served as a rabbi in Adrianople, and eventually resettled in Tzfat. At the time, Tzfat was experiencing a resurgence of Jewish life and a renaissance in Jewish scholarship, thanks mainly to an influx of Sephardic Jewish refugees. It soon became the “capital” of Jewish mysticism, and Rabbi Karo was one of its most famous mystics and scholars. It was in Tzfat that he composed the Shulchan Arukh, to this day the standard code of Jewish law worldwide. (Tzfat boasted one of the first printing presses in the Middle East, helping to spread the Shulchan Arukh far and wide and making it extremely popular and accessible.) The Shulchan Arukh was itself only a summary of the far broader and more complex Beit Yosef, which was Rabbi Karo’s true magnum opus that he worked on for over twenty years. Rabbi Karo opened his own yeshiva, with 200 students including the renowned “Ramak”, Rabbi Moshe Cordovero. Karo also served as the chief rabbi on the Tzfat beit din. In fact, he was one of the main leaders in a rabbinic attempt to re-establish the ancient Sanhedrin. Rabbi Karo was recognized as the preeminent authority for all Sephardic Jewry worldwide, and was deeply respected by Ashkenazi Jews as well who, on several occasions, asked him to intervene in local European disputes. Among his other noted publications are Kesef Mishneh, a commentary on the Mishneh Torah of Maimonides, along with a textbook for Talmudic study. One of his most intriguing works is Maggid Meisharim, a personal journal which records his prophetic experiences and the teachings he received from an angel over a period of fifty years. Rabbi Karo is often referred to simply as Maran, “Our Master”.

Today, what is demanded of the Jewish people is mesirut nefesh, self-sacrifice, and this is particularly true with regard to chinuch, education. The resources for which we have labored must be dedicated to the education of children – both our own, and the children of others.

Jew of the Week: Shimon Lavi

Father of Libyan Jewry

Shimon ibn Lavi (1486-1585) was born in Spain and exiled with his family during the Spanish Expulsion of 1492. The family settled in Fez, Morocco, where Lavi studied to become a rabbi. He then sought to make aliyah to the Holy Land, but was kidnapped along the way near Tripoli by Arab brigands. After being ransomed, he found the Tripoli Jewish community in need of a rabbi so he stayed there. It was Lavi who opened the city’s first yeshivas, established a beit din, and went on to make the city one of the largest Jewish communities in North Africa. He is often credited with being the “father of Tripoli Jews”. Rabbi Lavi was the community’s official representative to the government, and served as the Ottoman governor’s personal physician. He was also a major Kabbalist, alchemist, and mystic. In fact, he wrote the popular song “Bar Yochai”, in honour of Rabbi Shimon bar Yochai whose teachings would become the Zohar (the primary “textbook” of Kabbalah) and who is celebrated on Lag b’Omer. Lavi wrote a commentary on the Zohar called Ketem Paz, as well as a dictionary translating some of the Zohar’s most cryptic words. He was widely known as a miracle worker, and was revered by Jews and Muslims alike (the latter refer to him as “Ibn Limam”), with his tomb serving as a major pilgrimage site in Libya.

One of the saddest lessons of history is this: If we’ve been bamboozled long enough, we tend to reject any evidence of the bamboozle. We’re no longer interested in finding out the truth. The bamboozle has captured us. It’s simply too painful to acknowledge, even to ourselves, that we’ve been taken. Once you give a charlatan power over you, you almost never get it back.
