Atheism will appeal to psychology and sociology to explain human behavior, which is legitimate, but what explains human psychology? Atheism can only find explanatory power in evolution such that the mind is - paradoxically - a mindless organ that is forced to act according to its chemistry and cannot act otherwise.The fact that humans are capable of recognizing depravity in others, are offended by it, seek to reform it, feel guilt, and are capable of redemptive behavior all speak against this explanation.The fact that humans are capable of meta-cognition - thinking about thinking - and are therefore able to postulate their own mindlessness is counter-intuitive to say the least.

Once again, it is difficult to start from the premise of mindless evolution and end with the idea that humans are anything more than organisms bent on preserving and passing on their DNA. The fact that humans not only pursue art, philosophy, and science, but also exult in those things more than reproduction cannot easily be explained through materialism.
