Baruch Spinoza (/bəˈruːk spɪˈnoʊzə/; Dutch: [baːˈrux spɪˈnoːzaː]; born Benedito de Espinosa, Portuguese: [bɨnɨˈðitu ðɨ ʃpiˈnɔzɐ]; 24 November 1632 – 21 February 1677, later Benedict de Spinoza) was a Dutch philosopher of Sephardi/Portuguese origin. By laying the groundwork for the 18th-century Enlightenment and modern biblical criticism, including modern conceptions of the self and the universe, he came to be considered one of the great rationalists of 17th-century philosophy.
