Speaking of Spinoza he [Nietzsche] says: "How much of personal timidity and vulnerability does this masquerade of a sickly recluse betray!" Exactly the same may be said of him, with the less reluctance since he has not hesitated to say it of Spinoza. It is obvious that in his day-dreams he is a warrior, not a professor; all the men he admires were military. His opinion of women, like every man's, is an objectification of his own emotion towards them, which is obviously one of fear. "[Thou goest to woman?] Forget not thy whip"—but nine women out of ten would get the whip away from him, and he knew it, so he kept away from women, and soothed his wounded vanity with unkind remarks.
