More quotes by Otto Weininger

If man were not free, then he could not conceive of causality at all, and could not form any concept of it. Insight into lawfulness is already freedom from it.

Memory, then, is a necessary part of the logical faculty. … The proposition A = A must have a psychological relation to time, otherwise it would be At1 = At2.

Sex and Character (1903)

Woman, in short, has an unconscious life, man a conscious life, and the genius the most conscious life.

Sex and Character (1903)

Not only virtue, but also insight, not only sanctity but also wisdom, are the duties and tasks of mankind.

Sex and Character (1903)
