For, if we visited Mars or Venus keeping the same senses, they would clothe in the same aspect as the things of the earth everything that we should be capable of seeing. The only true voyage of discovery, the only fountain of Eternal Youth, would be not to visit strange lands but to possess other eyes, to behold the universe through the eyes of another, of a hundred others, to behold the hundred universes that each of them beholds, that each of them is.

— Marcel Proust, In Search of Lost Times
