“I am utterly amazed, utterly enchanted! I have a precursor, and what a precursor! I hardly knew Spinoza: that I should have turned to him just now, was inspired by “instinct.” Not only is his overtendency like mine—namely to make all knowledge the most powerful affect—but in five main points of his doctrine I recognize myself; this most unusual and loneliest thinker is closest to me precisely in these matters: he denies the freedom of the will, teleology, the moral world-order, the unegoistic, and evil. Even though the divergencies are admittedly tremendous, they are due more to the difference in time, culture, and science. In summa: my lonesomeness, which, as on very high mountains, often made it hard for me to breathe and make my blood rush out, is now at least a twosomeness. Strange! Incidentally, I am not at all as well as I had hoped. Exceptional weather here too! Eternal change of atmospheric conditions!—that will yet drive me out of Europe! I must have clear skies for months, else I get nowhere. Already six severe attacks of two or three days each!! — With affectionate love, Your friend”
Friedrich Nietzsche, found in a postcard to Franz Overbeck in Sils-Maria dated July 30, 1881.
In what ways (besides those already mentioned in the quote) are the philosophies of Spinoza and Nietzsche comparable?
