“So the negro has a strong sex drive. And since he actually has the sun, light and warmth there on his body surface, in his skin, his whole metabolism is working inside as if it´s cooked by the sun itself. Thats where the sex drive comes from.
Inside of the negro, all this is constantly truly cooked, and what is fanning the fire is the afterbrain.
And we europeans, we poor europeans, have got the thought-life, that is rooted in the brain.” (Rudolf Steiner)
