Meditações - a razão do movimento do relógio

...[T]he order of the reason of the mover appears in all things which are moved by reason, granted the thing itself which is moved by reason may not have reason; for thus does the arrow tend directly to the target from the motion of the archer, as if it itself had the reason of the one directing it. And the same appears in the motion of clocks, and of all works of human ingenuity, which come to be by art. However, just as artifacts are compared to human art, so also all natural things are compared to divine art. São Tomás de Aquino (Summa Theologica, I-II, q.13, art.2, ad. 3.)
