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

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.

And I also see how this body influences external images: it gives back movement to them.

Wherever anything lives, there is, open somewhere, a register in which time is being inscribed.

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

To exist is to change, to change is to mature, to mature is to go on creating oneself endlessly.

Europe is overpopulated, the world will soon be in the same condition, and if the self-reproduction of man is not rationalized... we shall have war.
