I have laboured carefully, not to mock, lament, or execrate human actions, but to understand them; and, to this end, I have looked upon passions, such as love, hatred, anger, envy, ambition, pity, and the other perturbations of the mind, not in the light of vices of human nature, but as properties, just as pertinent to it, as are heat, cold, storm, thunder, and the like to the nature of the atmosphere, which phenomena, though inconvenient, are yet necessary, and have fixed causes, by means of which we endeavour to understand their nature, and the mind has just as much pleasure in viewing them aright, as in knowing such things as flatter the senses

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.
