A single metaphor can give birth to love.

The beauty of New York is unintentional; it arose independent of human design, like a stalagmite cavern.

Children are the future, because mankind is moving more and more towards infancy.

I understand you, and I shall not attempt to make you change your mind. I am too old to want to improve the world. I have told you what I think, and that is all. I shall remain your friend even if you act contrary to my convictions, and I shall help you even if I disagree with you.

Unlike the puerile loyalty to a conviction, loyalty to a friend is a virtue - perhaps the only virtue, the last remaining one.

Humanity's true moral test, its fundamental test…consists of its attitude towards those who are at its mercy: animals.

Love is the longing for the half of ourselves we have lost.
