Abstract

I analyze different accounts of laws of nature: the Hume-Lewis regularity account, the Armstrong-Tooley relations between universals account, and my preferred account in terms of the powers and liabilities of individual substances. On any account it is most unlikely a priori that a universe would be governed by simple laws of nature. But if there is a God, it is quite probable that he will choose to create free agents of limited power, and to put them in a universe governed by simple laws of nature, in order that their purposes may have their intended effects. Hence, the operation of simple laws of nature confirms the existence of God.
