"I am neither a rou nor a degenerate; yet there are days when certain visions rise so definitely before me and I am a prey to such violent desires, that if, hitherto, I have been able to resist their attraction, it is impossible for me to say whether, an hour hence, I shall be able to do so. At other times, I feel strangely weary, as though I had just accomplished some gigantic task. I feel that my bones are broken, my muscles torn, and it is when I wake up that I feel this--when I wake up, after eight hours' sleep and rest, following no excess and troubled by no dreams. . . . I also have fits of inexplicable rage; of fury that would urge me to any crime; preconceived dislikes; I am so sensitive and excitable, that a word, a gesture, are sufficient to unhinge me: I suffer almost physically from all these things."
