“Those blacks in africa have the nature to suck up all the light and wamth from space. They consume that. And that light and that warmth in space can not pass through the whole body, because man always is man, even when he is black.
It does not pass through the whole body, but stays on the surface of the skin, and then the skin itself turns black.” (Rudolf Steiner)

“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)
