“Marriage is the triumph of imagination over intelligence. Second marriage is the triumph of hope over experience.”

La philosophie triomphe aisément des maux passés et des maux à venir. Mais les maux présents triomphent d'elle.
Maxim 22. Compare: "This same philosophy is a good horse in the stable, but an arrant jade on a journey", Oliver Goldsmith, The Good-Natured Man, Act i.

Context: The wise and subtle deities permit nothing worthy to be lost. It was with no thought of beauty that the builders labored; no conscious thought; they were masters or slaves in the bitter wars of commerce, and they never saw as a whole what they were making; no one of them did. But each one had had his dream. And the baffled dreams and the broken visions and the ruined hopes and the secret desires of each one labored with him as he labored; the things that were lost and beaten and trampled down went into the stone and steel and gave it soul: the aspiration denied and the hope abandoned and the vision defeated were the things that lived, and not the apparent purpose for which each one of all the millions sweat and toiled or cheated; the hidden things, the silent things, the winged things, so weak they are easily killed, the unacknowledged things, the rejected beauty, the strangled appreciation, the inchoate art, the submerged spirit — these groped and found each other and gathered themselves together and worked themselves into the tiles and mortar of the edifice and made a town that is a worthy fellow of the sunrise and the sea winds.
Humanity triumphs over its details.

"Credo" at his official website http://robertfulghum.com/index.php/fulghumweb/credo/; this may be partly influenced by remarks of Albert Einstein in "What Life Means to Einstein: An Interview by George Sylvester Viereck" The Saturday Evening Post (26 October 1929): I am enough of an artist to draw freely upon my imagination. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

Context: Christianity, if it is to triumph over pantheism, must absorb it. To our pusillanimous eyes Jesus would have borne the marks of a hateful pantheism, for he confirmed the Biblical phrase "ye are gods," and so would St. Paul, who tells us that we are of "the race of God." Our century wants a new theology — that is to say, a more profound explanation of the nature of Christ and of the light which it flashes upon heaven and upon humanity.
