Otto Weininger said this quote
“ The criminal (as slave) often seeks a person of great perfection (and here, as a judge of people's imperfection, the criminal is much harsher than a good man), because he so wants to obtain trust from outside (not through an inner change of mind). If he believes he has found such a person, he gives himself up to him in the most complete slavery, and he searches in an importunate manner for people whom he could serve as a slave. He also wants to live as a slave so as never to be alone. ”
