My soul is nothing now but the dream dreamt by matter struggling with itself! - Paul Valéry

But what, Phaedrus, is the contrary of a dream if not some other dream?… A dream of vigilance and tension dreamt by Reason herself!—And what would such a Reason dream?—If a Reason were to dream—a Reason hard, erect, eyes armed, mouth closed, as though mistress of her lips—would not the dream she dreamt be what we see now—this world of exact forces and studied illusions?—A dream, a dream, but a dream interpenetrated with symmetries, all order, acts and sequences!

It is therefore reasonable to think that the creations of man are made either with a view to his body, and that is the principle we call utility, or with a view to his soul, and that is what he seeks under the name of beauty. But, further, since he who constructs or creates has to deal with the rest of the world and with the movement of nature, which both tend perpetually to dissolve, corrupt or upset what he makes, he must recognize and seek to communicate to his works a third principle, that expresses the resistance he wishes them to offer to their destiny, which is to perish. So he seeks solidity or lastingness.

One should be light like a bird, and not like a feather.
