• The whole art of teaching is only the art of awakening the natural curiosity of young minds for the purpose of satisfying it afterwards.

• To accomplish great things, we must not only act, but also dream not only plan, but also believe.
• An education isn't how much you have committed to memory, or even how much you know. It's being able to differentiate between what you know and what you don't.

• An education which does not cultivate the will is an education that depraves the mind.
