For every one who sees a beautifully made lute, and considers the skill with which it has been fitted together and arranged, or who hears its melody, would think of none but the lutemaker, or the luteplayer, and would recur to him in mind, though he might not know him by sight. And thus to us also is manifested that which made and moves and preserves all created things, even though He be not comprehended by the mind. And very wanting in sense is he who will not willingly go thus far in following natural proofs.
