Why Was Spinoza Excommunicated? by Steven Nadler

Philosophy Seminar Series In July 1656, Bento (Baruch) de Spinoza was given the harshest herem (ban or ostracism) ever issued by the Amsterdam Portuguese-Jewish community. The text of the ban rains curses down upon the young man, for his “abominable heresies and monstrous deeds”. Unlike other bans issued by the community in the period, it was never rescinded. But why was Spinoza excommunicated with such prejudice? He was only twenty-three years old, not yet the famous (and “scandalous”) philosopher he would later become. In this lecture, we will consider the circumstances of the ban and use them as a way of examining some of the major themes of Spinoza’s philosophy.
