Modern man thinks he loses something - time - when he does not do things quickly. Yet he does not know what to do with the time he gains, except kill it.

Love means to commit oneself without guarantee, to give oneself completely in the hope that our love will produce love in the loved person. Love is an act of faith, and whoever is of little faith is also of little love.

The only way of full knowledge lies in the act of love; this act transcends thought, it transcends words. It is the daring plunge into the experience of union. To love somebody is not just a strong feeling-it is a decision, it is a judgment, it is a promise.

The history of man so far is nothing to brag about, from the standpoint of our ideas - and what I mean is, that in comparison with most other societies, our present-day American society has achieved things which are remarkable: material wealth, greater than for any other nation; a relative freedom from oppression; a relative mobility; a spreading of art, of music, of thought, which is also rather unique.

Love isn't something natural. Rather it requires discipline, concentration, patience, faith, and the overcoming of narcissism. It isn't a feeling, it is a practice.

That is not quite enough to make one happy, if one spends eight hours a day in something which in itself has no meaning and interest, except that one gains money from it.

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