Lenin's mind was hewn from the rock of Spinozism, and, because his mind imposed itself firmly upon Russia, Christianity in Russia actually was replaced with Spinozism. In all the thirty-four volumes of the collected works of Lenin, published by the Lenin Institute in Moscow, Spinoza's name occurs only once. The manner in which he refers to Spinoza makes it almost certain that if he knew him at all he knew him secondhand. [...] Lenin, however, was not the only ruthless politician who embraced Spinozism de facto. Bismarck, the iron chancellor, who forged the Wilhelminic German Empire, was also a disciple of Spinoza. [...] Hence, it is not blind chance that men like Lenin and Bismarck were Spinozists, either in fact or in theory.

Most writers on the emotions and on human conduct seem to be treating rather of matters outside nature than of natural phenomena following nature's general laws. They appear to conceive man to be situated in nature as a kingdom within a kingdom: for they believe that he disturbs rather than follows nature's order, that he has absolute control over his actions, and that he is determined solely by himself. They attribute human infirmities and fickleness, not to the power of nature in general, but to some mysterious flaw in the nature of man, which accordingly they bemoan, deride, despise, or, as usually happens, abuse: he, who succeeds in hitting off the weakness of the human mind more eloquently or more acutely than his fellows, is looked upon as a seer. [...] Such persons will, doubtless think it strange that I should attempt to treat of human vice and folly geometrically, and should wish to set forth with rigid reasoning those matters which they cry out against as repugnant to reason, frivolous, absurd, and dreadful. However, such is my plan.
