Each man's life represents a road toward himself, an attempt at such a road, the intimation of a path... But each of us - experiments of the depths - strives toward his own destiny. We can understand one another; but each of us is able to interpret himself to himself alone.

Only the ideas that we really live have any value.

Love can be begged, bought, or received as a gift, one can find it in the street, but one cannot steal it.

Nothing is harder, yet nothing is more necessary, than to speak of certain things whose existence is neither demonstrable nor probable. The very fact that serious and conscientious men treat them as existing things brings them a step closer to existence and to the possibility of being born.

The realization that my problem was one that concerned all men, a problem of living and thinking, suddenly swept over me and I was overwhelmed by fear and respect as I suddenly saw and felt how deeply my own personal life and opinions were immersed in the eternal stream of great ideas. Though it offered some confirmation and gratification, the realization was not really a joyful one. It was hard and had a harsh taste because it implied responsibility and no longer being allowed to be a child; it meant standing on one’s own feet.
