Rationalists pride themselves on believing in evolution, unlike dopey creationists. Per the theory of evolution, if we find that all, say, woodchucks engage in some behavior, and expand a great deal of energy in doing so, we should suspect that that activity is important to the woodchucks’ survival, even if we are not sure how. It would be very non-Darwinian of us to dismiss this behavior as “Just stupid woodchucks, doing something ridiculous and pointless.” And yet when it is noticed that all human societies ever have engaged in some form of behavior that can be characterized as religious, and have spent a great deal of energy doing so, these rationalists dismiss this behavior as “Just stupid humans, doing something ridiculous and pointless.”
