"Bodily exercise, when compulsory, does no harm to the body; but knowledge which is acquired under compulsion obtains no hold on the mind."
"Those who don't know must learn from those who do."
"The philosopher whose dealings are with divine order himself acquires the characteristics of order and divinity."
"That's what education should be,"I said, "the art of orientation. Educators should devise the simplest and most effective methods of turning minds around. It shouldn't be the art of implanting sight in the organ, but should proceed on the understanding that the organ already has the capacity, but is improperly aligned and isn't facing the right way."
