"La science, mon garçon, est faite d'erreurs, mais d'erreurs qu'il est bon de commettre, car elles mènent peu à peu à la vérité." -- Professor Otto Lidenbrock, in Voyage au centre de la Terre, 1864 (English translation, 1871, Journey to the Center of the Earth) by Jules Verne (b. 1828-02-08, d. 1905-03-24)

My attempt at translation: "Science, my boy, is built of errors, but errors that were good to make, for they led bit by bit to the truth."

Wikiquote: "Science, my lad, has been built upon many errors; but they are errors which it was good to fall into, for they led to the truth."

[I think the "bit by bit" or "little by little" ("peu à peu") matters for representing how science develops.]
