About Baruch Spinoza

Benedictus de Spinoza (24 November 1632 – 21 February 1677) was a social and metaphysical philosopher known for the elaborate development of his monist philosophy, which has become known as Spinozism. Controversy regarding his ideas led to his excommunication from the Jewish community of his native Amsterdam. He was named Baruch ("blessed" in Hebrew) Spinoza by his synagogue elders and known as Bento de Spinoza or Bento d'Espiñoza, but afterwards used the name Benedictus ("blessed" in Latin) de Spinoza.
