If I am what I have and if I lose what I have who then am I?

If I am attached to another person because I cannot stand on my own two feet, he or she may be a life saver, but the relationship is not one of love.

Thus, the ultimate choice for a man, inasmuch as he is driven to transcend himself, is to create or to destroy, to love or to hate.

Modern man, if he dared to be articulate about his concept of heaven, would describe a vision which would look like the biggest department store in the world, showing new things and gadgets, and himself having plenty of money with which to buy them.

Man unites himself with the world in the process of creation.

What is it that distinguishes man from animals? It is not his upright posture.

Man is the only animal for whom his own existence is a problem which he has to solve.
