Education is a private matter between the person and the world of knowledge and experience, and has little to do with school or college.

Faith and doubt both are needed -- not as antagonists, but working side by side -- to take us around the unknown curve.

To believe in something not yet proved and to underwrite it with our lives: it is the only way we can leave the future open.

The human heart does not stay away too long from that which hurt it most. There is a return journey to anguish that few of us are released from making.

When you stop learning, stop listening, stop looking and asking questions, always new questions, then it is time to die.
