All excellent things are as difficult as they are rare.

Baruch Spinoza

Baruch or Benedict de Spinoza (Portuguese: Bento de Espinosa, Latin: Benedictus de Spinoza) (November 24, 1632 - February 21, 1677) was a Dutch philosopher of Portuguese Jewish origin. Revealing considerable scientific aptitude, the breadth and importance of Spinoza's work was not fully realized until years after his death. Today, he is considered one of the great rationalists of 17th-century philosophy, laying the groundwork for the 18th century Enlightenment and modern biblical criticism. By virtue of his magnum opus, the posthumous Ethics, in which he opposed Descartes' mind-body dualism, Spinoza is considered to be one of Western philosophy's most important philosophers
