Loose paraphrase of Salviati on Day 3 http://law2.umkc.edu/faculty/projects/ftrials/galileo/dialogue3.html: "For when the sun draws up some vapors here, or warms a plant there, it draws these and warms this as if it had nothing else to do. Even in ripening a bunch of grapes, or perhaps just a single grape, it applies itself so effectively that it could not do more even if the goal of all its affairs were just the ripening of this one grape."
