Ordinarily, I try not to make this blog into a “today on QT3” sort of thing, but at times something comes up that’s too interesting and relevant to my own interests to ignore.

A poster on QT3 recently linked to an article by Dinesh D’Souza attacking atheism based on Immanuel Kant’s Critique of Pure Reason. Admittedly, the argument does not constitute an affirmation of theism. It merely seeks to demonstrate what D’Souza considers to be a failing of atheism. Essentially, D’Souza argues that, as Kant pointed out, the province of reason is limited to the things that we can perceive and to the things as we can perceive them. This means that we have no way of knowing what Kant calls the noumena, the things as they are in themselves, unfiltered by the limitations of human perception, and to D’Souza this opens to door to religious faith.

Within hours of the original post however, QT3 member Hawkeye Fierce posted an excellent response:

Kant’s Critique of Pure Reason has always seemed like a lot of mental masturbation to me. He says that the capacities of reason are limited because our perception is limited, and that there could exist phenomena that we are simply incapable of perceiving in any way. I suppose that could be true, but if we are unable to perceive these phenomena, I don’t see how it follows that we should act any differently. Reality may be bigger than we can perceive, but if the part that we can’t see can’t actually affect us, it may as well not exist. And if it can affect us, well then it’s no longer imperceptible. Also, without experiential information, all theories about what the imperceptible universe is like are equally valid and invalid, so there’s no reason to pick one over the other.

I can really put it no better than the above. D’Souza writes that he tried to get a rebuttal from Daniel Dennett but didn’t get a satisfactory response. This seems like a pretty good response to me.
