The idea of the future, pregnant with an infinity of possibilities, is thus more fruitful than the future itself, and this is why we find more charm in hope than in possession, in dreams than in reality.

There is no greater joy than that of feeling oneself a creator. The triumph of life is expressed by creation.

Men do not sufficiently realize that their future is in their own hands. Theirs is the task of determining first of all whether they want to go on living or not. Theirs is the responsibility, then, for deciding if they want merely to live, or intend to make just the extra effort required for fulfilling, even on this refractory planet, the essential function of the universe, which is a machine for the making of gods.

It is of man's essence to create materially and morally, to fabricate things and to fabricate himself. Homo faber is the definition I propose ... Homo faber, Homo sapiens, I pay my respects to both, for they tend to merge.

We are free when our actions emanate from our total personality, when they express it, when they resemble it in the indefinable way a work of art sometimes does the artist.

When we make the cerebral state the beginning of an action, and in no sense the condition of a perception, we place the perceived images of things outside the image of our body, and thus replace perception within the things themselves.

Homo sapiens, the only creature endowed with reason, is also the only creature to pin its existence on things unreasonable.
