Sanity is only that which is within the frame of reference of conventional thought.

Happiness is a man's greatest achievement; it is the response of his total personality to a productive orientation toward himself and the world outside.

There is nothing inhuman, evil, or irrational which does not give some comfort, provided it is shared by a group.

Man can only know the nagation, never the position of ultimate reality.

We are confronted with the possibility of a war of such destruction that the whole existence of our nation and of the whole world is at stake. And yet, people know it - people read it in the newspapers, people read that at the first attack, a hundred million Americans might be killed.

Can one have love? If we could, love would need to be a thing, a substance that one can have, own, possess. The truth is, there is no such thing as love. Love is an abstraction, perhaps a goddess or an alien being, although nobody has ever seen this goddess. In reality, there exists only the act of loving. To love is a productive activity. It implies caring for, knowing, responding, affirming, enjoying: the person, the tree, the painting, the idea. It means bringing to life, increasing his/her/its aliveness. It is a process, self-renewing and self increasing.
