Love is active penetration of the other person, in which my desire to know is stilled by union. In the act of fusion I know you, I know myself, I know everybody - and I "know" nothing.

I shall become a master in this art only after a great deal of practice.

Only the person who has faith in himself is able to be faithful to others.

Today it is not alive. What, then, is this experience of humanism? With the above survey I have tried to show you that the experience of humanism is that — as Terence expressed it — “Nothing human is alien to me”; that nothing which exists in any human being does not exist in myself. I am the criminal and I am the saint. I am the child and I am the adult. I am the man who lived a hundred thousand years ago and I am the man who, provided we don't destroy the human race, will live hundred thousand years from now.

Whether...a change from the supremacy of natural science to a new social science will take place...depends on one factor: how many brilliant, learned, disciplined, and caring men and women are attracted by the new challenge.

If faith cannot be reconciled with rational thinking, it has to be eliminated as an anachronistic remnant of earlier stages of culture and replaced by science dealing with facts and theories which are intelligible and can be validated.

It seems that great minds a hundred years ago saw what would happen today or tomorrow, while we to whom it is happening blind ourselves in order not to be disturbed in our daily routine.
