Effectiveness of Philosophy
Most of the defenses of Christianity are philosophical. But one of my main wonders is how reliable can philosophy (or theology for that matter) be if both rely on human logic, which is usually known to be flawed or just plain wrong.
For instance, in William Paley's day, his watchmaker theology was pretty much irrefutable. Some people didn't buy it, but they weren't able to come up with a better answer for the appearance of life on Earth. Then Charles Darwin came along, and everything changed, and the truth of Evolution showed us how we came to be in a way that we never would have imagined possible. Some people challenge evolution (as we all know) by claiming that there is no way that such and such could have evolved naturally. They claim that it had to have been created and then, when we challenge that, they claim that we assume that it can because we have a naturalistic bias. But isn't it just as fair to assume that they merely claim that there IS a supernatural cause because of their supernaturalistic bias?
Anyway, my point is I don't think that, no matter how sophisticated theology and philosophy are, I don't think they are the way we ultimately discover how life and the universe operate.
Our job on this Earth, is to take care of each other. Something that we have ultimately failed at doing, hence why we are so miserable.
