Song Of The Week #11 - Reason, or, The Problem of Evil, part 1

I think it's safe to say that this is probably the weirdest song you've ever heard; it is definitely the weirdest song The Redding Brothers have ever created.

First of all, it's a cappella.
Secondly, it sounds like 50s doo-wop.
Thirdly, the background is Micah reading a philosophical treatise.

Extra points if you find said treatise and post the link in the comments.
