The notion of omnipotence has proved to be quite recalcitrant to analysis. Still, during the last three decades or so, there has resurfaced a clever argument to the effect that, whatever omnipotence is, it cannot be exemplified in God: an allegedly impeccable and all-perfect being. Scrutinizing this argument, however, I find it less than convincing. Moreover, and more importantly, I venture a positive account of my own: a non-technical and distinctively metaphysical definition of omnipotence which, if true, sidesteps quite a (...) number of well-known pitfalls. Also, by way of introduction, I review some earlier attempts. (shrink)

I discuss Thomas Aquinas’ views on being, power, and logic, and show how together they provide rebuttals against certain principal objections to the notion of divine omnipotence. The objections I have in mind can be divided into the two classes. One says that the notion of omnipotence ends up in self-contradiction. The other says that it ends up contradicting certain doctrines of traditional theism. Thomas’ account is frequently misunderstood to be a version of what I call a ‘consistent description’ account (...) of omnipotence, which is a standard contemporary account. That account of omnipotence, however, succumbs to certain contemporary objections. Thomas’ account withstands those objections because of his view of logic and, specifically self-contradiction. Moreover, a certain thesis found in Thomas’ understanding of God, but almost entirely absent from contemporary debates about omnipotence, is that God is not just a being, but the source of being. This thesis, I argue, puts Thomas’ account in a position that differs greatly from many contemporary accounts since the scope of possibility, and specifically the scope of what possible powers there are, is ultimately grounded in God’s being. Further still, many contemporary accounts of omnipotence do not seek to establish substantive account of power itself. Thomas, by contrast, has a robust and independent account of what power is. And that account informs his account of what it is to have all powers, or to be omnipotent, in a way that makes his account resistant to contemporary objections. Against contemporary objections, Thomas’ account of omnipotence can sustain the claim that God can do all things. (shrink)

Several recent arguments purport to show that omnipotence is incompatible with the possession of various necessary properties. These arguments appeal to one of two plausible but false principles about the nature of power: that if it is metaphysically impossible for a being to actualize a state of affairs, then that being does not have the power to actualize that state of affairs, or that if it is impossible given some contingent facts about the world that a being actualize a state (...) of affairs, then that being does not have the power to actualize that state of affairs. I pose several problems for both principles, thereby undermining the plausibility of these arguments. I then consider the implications of rejecting these principles for related principles in the free will debate. These implications suggest important differences between having the power to bring about a state of affairs, having a choice about whether it obtains, and being able to bring it about. (shrink)
