Rémy De Gourmont said this quote

Well, suppose we remain upon earth, after all? Suppose we bravely accept the death of our dreams at the same time as the death of our bodies? This beyond is decidedly uncertain, quite vague and mobile. I do not believe that it exists everywhere; I believe that it is nowhere except in our infantile imaginations. Born with us, it will end at the same moment that we do, to be born anew in our posterity. The beyond is the earthly tomorrow, as we bequeath it to our heirs and as they modify it by their efforts and in accordance with their tastes.
