...In a few words, we can define the true relation of Spinozist teaching on passions to explanatory and descriptive psychology of emotions, saying th… - Benedictus de Spinoza

الإنسان الحر لا يفكر في الموت إلا أقل القليل؛ فحكمته تسوقه إلى إمعان التفكير

...For natural science he [Otto von Bismarck] shewed little interest, and indeed at that time it scarcely could be reckoned among the ordinary subjects of education; philosophy he pursued rather as a man than as a student, and we are not surprised to find that it was Spinoza rather than Kant or Fichte or Hegel to whom he devoted most attention, for he cared more for principles of belief and the conduct of life than the analysis of the intellect. ...He [Otto von Bismarck] astonished his friends by the amount and variety of his reading; it was at this time that he studied Spinoza. It is said that he had among his friends the reputation of being a liberal; it is probable enough that he said and did many things which they did not understand; and anything they did not understand would be attributed to liberalism by the country gentlemen of Pomerania; partly no doubt it was due to the fact that in 1843 he came back from Paris wearing a beard.

As the French philosopher Louis Althusser wrote in his 1976 Essays in Self-Criticism, much late 20th century Spinozism has proceeded by ‘attributing to the author of the Tractatus Theologico-Politicus and the Ethics a number of theses which he would surely never have acknowledged, though they did not actually contradict him. But to be a heretical Spinozist is almost orthodox Spinozism, if Spinozism can be said to be one of the greatest lessons in heresy that the world has seen!’. Though Spinozists have existed ever since the radical circles that rippled through Europe in the wake of Spinoza's death, I think it is fair to say that only in the past 50 years or so has there been a Spinozism to match in hermeneutic rigour and creative interventions the history of Kantianism or Hegelianism, that only now has the hereticism that Althusser referred to been complemented by the labour of the concept. Arguably, it is only now then that the scope of his thought and its relevance to our social and political existence can be truly appreciated, at a historical juncture when the communicative power of the multitude and of what Marx called the general intellect is so intensified that the physics, ethics, ontology and politics of Spinoza (what are ultimately indissociable facets of his philosophizing) can be thought simultaneously. Today more than ever, one might argue, is Spinoza, as Pierre Macherey puts it, ‘an irreplaceable reactor and developer’.
