Spinoza, Epicurus and the question of ‘epikoros’

With surprise, I heard from a Jewish friend that a Hebrew term for a heretic is epikoros, apparently derived from the Greek philosopher Epicurus (341-270 bc). The word cropped up recently in a row over a film on the life of Baruch Spinoza, showing that he is not forgiven more than 360 years after his expulsion from the Sephardic community in Amsterdam.

An American professor of philosophy, Yitzhak Melamed, asked the Portuguese Jewish synagogue there for permission to film some footage. The rabbi pointed out that Spinoza had been excommunicated ‘with the severest possible ban, a ban that remains in force for all time’. So, no he could not visit the synagogue.

The rabbi’s letter called Spinoza an epikouris, a form of the word used of him in the 17th century. The reason for Spinoza’s excommunication (herem in Hebrew) is unknown. Spinoza did write difficult stuff later about all things being God, but not when he was cast out in 1656, aged 23.

Anyway, 12th-century Jewish philosopher Moses Maimonides discussed the nature of an epikoros as someone who denies God’s providence. That is what Spinoza was to deny, as far as I can understand him, and what Epicurus had denied.

To add a complication. Maimonides said in an early work that epikoros came from Aramaic, and others have since derived it from the p-q-r Semitic root, signifying ‘licentiousness’. By the time he wrote Guide for the Perplexed, Maimonides had learnt about Epicurus’s philosophy. Do, then, epikoros and a modern form, apikoros, come from the Greek philosopher, or was his fame projected on to an extant Semitic word? Professor Melamed eventually received a letter from the Ma’amad (churchwardens) of the synagogue saying the rabbi had exceeded his authority and he was welcome to visit. It was too late for the film, which has already been released, a sympathetic portrait of Spinoza.
