Young man, the secret of my success is that an early age I discovered that I was not God.

A child's education should begin at least one hundred years before he is born.

It seems to me that at this time we need education in the obvious more than the investigation of the obscure.

I have no respect for the passion of equality, which seems to me merely idealizing envy.

A mind that is stretched by a new experience can never go back to its old dimensions.
