When the past no longer illuminates the future, the spirit walks in darkness.

I cannot help fearing that men may reach a point where they look on every new theory as a danger, every innovation as a toilsome trouble, every social advance as a first step toward revolution, and that they may absolutely refuse to move at all.

The debates of that great assembly are frequently vague and perplexed, seeming to be dragged rather than to march, to the intended goal. Something of this sort must, I think, always happen in public democratic assemblies.

Democracy and socialism have nothing in common but one word, equality. But notice the difference: while democracy seeks equality in liberty, socialism seeks equality in restraint and servitude.

No individual has done more to help me pursue a career in science than my wife of forty-five years. I met Enid Cassandra Morgan during the election campaign of 1948 when she was a Sunday school teacher, a leader of the youth organizations of St. Phillips Episcopal Church, and the head of Harlem Youth for the election of Henry Wallace.

I was funny in a way that was not dissing the teacher; I was funny just to be funny. A real charmer with a prominent mustache that he didn't know what to do with and a smart-alecky attitude.

I'm forming a charitable institution for education.

When it comes to education, there is no one site you can point to that you can say, 'They speak to the world, and that is the site where you go to learn.'
