The world was not created once and for all time for each of us individually. There are added to it in the course of our life things of which we have never had any suspicion.

Medicine being a compendium of the successive and contradictory mistakes of medical practitioners, when we summon the wisest of them to our aid, the chances are that we may be relying on a scientific truth the error of which will be recognized in a few years time.

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.

The only true voyage would be not to travel through a hundred different lands, but to see the same land through a hundred different pairs of eyes.

Facts do not find their way into the world in which our beliefs reside; they did not produce our beliefs, they do not destroy them; they may inflict on them the most constant refutations without weakening them, and an avalanche of afflictions or ailments succeeding one another without interruption in a family will not make it doubt the goodness of its God or the talent of its doctor.

What artists call posterity is the posterity of the work of art.

The loss of a sense adds as much beauty to the world as its acquisition.
