Otto Weininger

“Logic and ethics are fundamentally the same, they are no more than duty to oneself.”

“The great man is he who is strongest in patience.”

“A man's worth is the value he places on himself.”

“Genius is a universal comprehension.”

“No men who really think deeply about women retain a high opinion of them; men either despise women or they have never thought seriously about them.”

“The age of a woman is not important: you can be wonderful at 30, charming at 40 and irresistible for the rest of your life.”

“The problem of women is the problem of humanity.”

“To be a genius is to be one's own law.”

“The great man is not convulsible. He may be capable of passionate emotion, but not of excitement.”

“A person's sense of morality is a measure of their distance from the ideal.”

“The woman is only sexual, the man is also sexual.”

“Woman is not amoral, but, rather, morality has no meaning for her.”

“The deepest, the most mysterious and the most feminine of all human phenomena is the religious instinct.”
