“But a kind of genius can come of this deprivation of sensation, of experience. It has been mistaken as naïve intelligence, when in fact it is empty intelligence, pure intelligence. The composition of the mind is altered. Its previous cultivation is disintegrated and it has greater access to the brain, the body: it is Supersanity. Learning is turned inside out. You have to start from the top and work your way down. You must study mathematical theory before simple arithmetic; theoretical physics before applied physics; anatomy, you might say, before you can walk.”
