Quite a few of the objections I hear to theism are based in a particular understanding of theology. It amazes me how many of them come from people who insist ardently that we shouldn’t engage in theology. Alex Rosenberg is a good example; after arguing that all knowledge is scientific (and, consequently, that theology should be ignored as a source of knowledge), he writes this:
A version of theism worth believing must at a minimum attribute to God the intention to produce us and not just some intelligent creature or other (The Atheist’s Guide to Reality, p. 88)
I have no idea how, without undertaking some theology, Rosenberg can reasonably claim to know this. Is it really crucial the teaching of every religion, and even the concept of God, that God meant to produce humans specifically? Is it completely unbelievable that he’d be willing to create (or even did create) different species elsewhere in the universe? Whether one answers ‘yes’ or ‘no’, one has gotten into theology.
This is a common problem. In fact, it is not unlike the oft-heard complaints about the idea that God would have created the whole universe “just for us”. It wasn’t until I heard this complaint that I’d ever even considered the idea that humans are God’s only reason for creating the universe. I’d always assumed that there were many things about creation which God intended. Again, we’re discussing theology whether or not I’m correct.
It is also worth mention that, even if we accept Rosenberg’s position, this is no discredit to theism. He goes on to claim that God couldn’t have seriously intended create us because our coming into being was so improbable. Of course, one would think that doing the improbable would be within the capacity of an omniscient and omnipotent God.
But Rosenberg doesn’t stop to consider such an objection. Doing so would be to partake of the forbidden fruit of studying theology. Never mind that his own position is every bit as theological–the only difference is that it is terrible theology.
This is the reason why so many have argued that an understanding of theology is needed in order to refute God’s existence. It is the only way to know whether or not God, as he is actually defined, is even being addressed by one’s argument.
