“One can be absolutely truthful and sincere even though admittedly the most outrageous liar.”

Postcard to Franz Overbeck, Sils-Maria (30 July 1881) as translated by Walter Kaufmann in The Portable Nietzsche (1954)
Context: 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.
