The realpolitik view of the individual human—that we are slaves to our desires and attitudes and that knowledge and rationality are necessarily secondary to these other factors—is simply wrong. We have the competence to be knowledgeable and rational, especially when we interact freely with each other. We can indeed change our minds. We can “bend over backward to be defense attorneys against our own pet ideas.” We can reconsider. We can be rational.

Prior to studies of unusually intelligent people that showed them to be generally much better adapted and happier than others, the popular belief in the United States was that exceptional intelligence was often associated with exceptional ability to “drive yourself nuts.” Hence, people believed that genius and lunacy were intimately connected. Perhaps, nearly all of us “drive ourselves a little nuts” by virtue of creating stories that lead us to the illusion that we understand history, other people, causality, and life—when we don’t.

Thus, logic and mathematics are important in determining “what is,” though not necessarily implying what is. “What is” must be consistent with logic, namely, with “what could be.”
Why? I don’t know. To me one of the great mysteries of life is that by simply thinking logically we can determine a lot about the universe—or at least conclude what can’t be, which together with empirical observation leads us to some pretty good ideas about what is.
