I should attempt to treat human vice and folly geometrically... the passions of hatred, anger, envy, and so on, considered in themselves, follow from… - Benedictus de Spinoza

I believe in Spinoza's God, who reveals himself in the lawful harmony of the world, not in a God who concerns himself with the fate and the doings of mankind.

Spinoza's philosophy introduced an unprecedented theoretical revolution in the history of philosophy, probably the greatest philosophical revolution of all time, insofar as we can regard Spinoza as Marx's only direct ancestor, from the philosophical standpoint. However, this radical revolution was the object of a massive historical repression, and Spinozist philosophy suffered much the same fate as Marxist philosophy used to and still does suffer in some countries: it served as damning evidence for a charge of ‘atheism’. The insistence of the seventeenth and eighteenth century establishment's hounding of Spinoza's memory, and the distance every writer had ineluctably to take with respect to Spinoza in order to obtain the right to speak (cf. Montesquieu) are evidence both of the repulsion and the extraordinary attraction of his thought. The history of philosophy's repressed Spinozism thus unfolded as a subterranean history acting at other sites (autres lieux), in political and religious ideology (deism) and in the sciences, but not on the illuminated stage of visible philosophy. And when Spinoza re-appeared on this stage in German idealism's ‘Atheismusstreit’, and then in academic interpretations, it was more or less under the aegis of a misunderstanding.

The book recognized as containing the most complete attempt at explaining and defending pantheism from a philosophical perspective is Spinoza's Ethics, finished in 1675 two years before his death. In 1720 John Toland wrote the Pantheisticon: or The Form of Celebrating the Socratic-Society in Latin. He (possibly) coined the term “pantheist” and used it as a synonym for “Spinozist.”
