How can we improve our thinking? The answer in principle is straightforward. What we need is to have an unlimited working memory for holding information in mind while we think about it, to know everything, to think at the speed of light about all the possibilities consistent with what we know and about all the counterexamples inconsistent with it. With these accomplishments, we would be able to solve hitherto intractable problems. We would avoid errors that we would otherwise make – some of which have catastrophic consequences. We would outthink other people. We might believe that their mental powers are defective; and they would despise us for our uncanny ability. If we all had these superhuman abilities then we would live longer – intelligent individuals do, and we might be wiser and live in a better world than we do now.
