Otto Weininger Quotes
Colour-blindness always extends to the complementary colours. Those who are red blind are also green blind; those who are blind to blue have no consciousness of yellow. This law holds good for all mental phenomena; it is a fundamental condition of consciousness.
Weininger, Otto. Sex and Character. William Heinemann, 1906.
Otto Weininger was an Austrian thinker who lived in the Austro-Hungarian Empire. In 1903, he published the book Geschlecht und Charakter (Sex and Character), which gained popularity after his suicide at the age of 23. Parts of his work were adapted for use by the Nazi regime (while at the same time denouncing him). Weininger was a strong influence on Ludwig Wittgenstein, August Strindberg, and, via his lesser-known work Über die letzten Dinge, on James Joyce.
