An artist never really finishes his work, he merely abandons it.
 Paul Valery
No work of art is ever completed, it is only abandoned.
 Paul Valery
In the eyes of those lovers of perfection, a work is never finished - a word that for them has no sense - but abandoned; and this abandonment, whether to the flames or to the public (and which is the result of weariness or an obligation to deliver) is a kind of an accident to them, like the breaking off of a reflection, which fatigue, irritation, or something similar has made worthless.
 Paul Valery
A poem is never finished, only abandoned.
 Paul Valery
The "determinist" swears that if we knew everything we should also be able to deduce and foretell the conduct of every man in every circumstance, and that is obvious enough. But the expression "know everything" means nothing.
