For what we suppose to be our love or our jealousy is never a single, continuous and indivisible passion. It is composed of an infinity of successive loves, of different jealousies, each of which is ephemeral, although by their uninterrupted multiplicity they give us the impression of continuity, the illusion of unity.

Our vanity, our passions, our spirit of imitation, our abstract intelligence, our habits have long been at work, and it is the task of art to undo this work of theirs, making us travel back in the direction from which we have come to the depths where what has really existed lies unknown within us.

Thanks to art, instead of seeing one world only, our own, we see that world multiply itself and we have at our disposal as many worlds as there are original artists, worlds more different one from the other than those which revolve in infinite space, worlds which, centuries after the extinction of the fire from which their light first emanated, whether it is called Rembrandt or Vermeer, send us still each one its special radiance.
