Our biggest problem

Our biggest problem is not anything external to ourselves; it's us, plain and simple. I may write a lot about the flaws inherent in biological systems, the likelihood of there having never been a designer, etc., but I do not pretend that meta-cognition is not important; in fact, understanding what makes your brain work and how to logically process data is the only way that you'll ever be able to competently address any external problem, no matter how ostensibly fundamental or obvious it might be.
