“Blonde hair and black hair are the two poles of human nature. Black hair signifies virility, courage, frankness, activity, whereas blonde hair symbolises femininity, tenderness, weakness, and passivity. Therefore a blonde is in fact doubly a woman. A princess can only be blonde. That's also why, to be as feminine as possible, women dye their hair yellow- but never black" "I'm curious about how pigments exercise their influence over the human soul", said Bertlef doubtfully. "it's not a matter of pigments. A blonde unconsciously adapts herself to her hair. Especially if the blonde is a brunette who dyes her hair yellow. She tries to be faithful to her hair colour and behaves like a fragile creature, a shallow doll, she demands tenderness and service, courtesy and alimony, she's incapable of doing anything for herself, all refinement on the outside and coarseness on the inside. If black hair became a universal fashion, life on this world would clearly be better. It would be the most useful social reform ever achieved.”
