How stupid our old hunter-gatherer ancestors must have been! They chose their actions based on incomplete information! It's a good thing that kind of thing has become antiquated among our intellectual upper class. A question for you: what's the use of predicting reality if you have no emotional investment in it? The mere act of trying to predict reality to further some end means you have an emotional objective. The universe can get along just fine without you, you know. Also, how do you determine when your rules have accurately predicted reality? Can you measure your own confirmation bias or congruence bias? Can you be sure that you've rid yourself of your bias blind spot when you make the connection between your mental model and what you perceive as reality? There are not turtles all the way down. At some level you enter the exciting, terrifying, wonderful, and dangerous world of raw human emotion. Emotions aren't antiquated. They are the turbulent foundation upon which rationality stands. I'm not saying that rationality is baseless or impossible. I'm just saying that you cannot set it apart as a motivational engine that supersedes human passion. I see it more as a system that helps you make effective use of your emotional energy. Additionally, you can't set up your definition of rationality (a set of self-consistent rules that allow you to accurately predict reality) as a system that encourages morality (rejecting things like torture or other needless suffering, as you said above).
