This is in response to a friend’s critique of my argument for the existence of God.
Quote:
Change is something existing potentiality becoming an actuality. Only what is already actual can cause something to go from potentiality to actuality.
Comment:
If we end up agreeing that there would have to originally be an entity that caused everything to go from potentiality to actuality, it doesn’t mean that the uncaused cause created all potentiality. The argument hinges on the relationship between things transitioning between states, but doesn’t comment on potentiality itself. Since the goal of the argument is typically to show that an entity that not just caused the events to begin but caused everything to exist, the argument would fall short.
I would guess the response to this criticism would have to posit qualities of potentialities that are beyond our experience. Since we simply have experience of things changing from potentiality to actuality, much of the proposed qualities of potential entities would be unfounded speculation.
You claim that the goal of the argument is to establish an entity that caused everything to exist. (What do you mean by “typically”? Do you mean the goal of cosmological arguments is typically to establish the cause of the existence of all things?) The goal of this argument, for Aristotle, was to determine the cause, or explanation of all motion. The goal for Aquinas (according to some Thomists) was to establish the existence of a being worthy of the name God, or god. So, it is hardly a critique to say the argument establishes the existence of a being who is the cause of all change, but does not establish that this being also created all things. After all, it would be a strange sort of atheism to grant that a supernatural being exists who causes all change. Continue reading →
