Love of All Wisdom

In my intro religious studies course last semester, I taught a unit on theism and evolution. This was the first time it really hit me that God had once been considered a verifiable – and confirmed – scientific hypothesis. Until he made his famous voyage, Charles Darwin, just like so many medieval philosophers, had looked at organisms’ suitability for their environments and concluded it must have been the work of an intelligent designer. The particular theory that had best fit the available empirical evidence, Darwin and most of his contemporaries thought, was Charles Lyell’s view that there were “centres of creation,” different places on earth where divine creative activity had been focused. In an era of rapid-discovery science like our own, that had been the best available hypothesis.

Then, the HMS Beagle made its famous voyage to the Galàpagos Islands, where Darwin observed his famous finches. A huge variety of birds, each on different islands and looking dramatically different, each well suited to the conditions of its own island – but they all turned out biologically to be finches, closely related to each other and to the finches of distant South America. It seemed needlessly complex to suggest that God would create so many different birds in so many different places and yet make them all part of the same family. A more straightforward hypothesis was that the different finches had evolved from a common ancestor, by natural selection. God was no longer needed as a scientific hypothesis – and hasn’t been needed since.

In retrospect, the point that God was once a legitimate hypothesis seems obvious to me now. But when I encountered it, it came to me as something of a surprise, because I’m so used to living in a world where any attempt to find empirical evidence for God’s existence looks like a desperate grasping at straws.

I’m really enjoying Alasdair MacIntyre’s new book God, Philosophy, Universities. I appreciate MacIntyre’s ability to get succinctly to the heart of bewildering and perplexing philosophical concepts. Especially, reading MacIntyre on the great Muslim philosopher ibn Rushd (Averroës), I finally feel like I have a handle on Aristotle’s theory of “causes.” We are often told that Aristotle believes in four kinds of causes – formal, material, effective and final – and that these causes lead back in a chain to a First Cause, which later theistic philosophers like ibn Rushd would come to identify with the Islamic or Christian God. This all left me bewildered. How can a thing’s final cause (which is to say its purpose) be considered a cause of it? Can God really be reduced merely to the first link in a causal chain of events? Such a god barely seems to matter. (continue reading…)

You believe that there is no God? Well, what is God? Suppose that God is the greatest being that can be conceived. Now even if you don’t think that such a being exists, you can still understand the idea of such a being; you can still conceive of it. Therefore, whether or not such a being exists in reality, it must at least exist in your mind. But a being that existed in reality would be greater than a being that existed only in your mind. Therefore, for such a being to exist only in your mind, and not in reality, would be a contradiction in terms; for if it existed only in your mind, it would both be the greatest being that can be conceived (that’s what you’re conceiving of) and not be the greatest thing that can be conceived (because the same being existing in reality would be greater). So the greatest being that can be conceived – this being must exist in reality as well as in thought.

This is a simplified version of Anselm’s argument for the existence of God, often called the “ontological” argument. I’m not sure whether it really works; I’m inclined to say it doesn’t, although it’s hard to say where the logic goes wrong, especially in the more sophisticated version presented by Anselm himself.

Nevertheless, I consider it the best and most important of the proofs of God’s existence, even if it doesn’t work. Why? (continue reading…)
