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.

There is nothing in philosophy which could not be said in everyday language.

I believe I experience creativity at every moment of my life.

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.

The universe... is a machine for the making of gods.

Only those ideas that are least truly ours can be adequately expressed in words.

I believe that the time given to refutation in philosophy is usually time lost. Of the many attacks directed by many thinkers against each other, what now remains? Nothing, or assuredly very little. That which counts and endures is the modicum of positive truth which each contributes. The true statement is, of itself, able to displace the erroneous idea, and becomes, without our having taken the trouble of refuting anyone, the best of refutations.
