The sad truth is that the saints we revere for thinking for themselves almost always end up thinking by themselves. We are disappointed to find that the self-taught are also self-centered, although a moment’s reflection should tell us that you have to be self-centered to become self-taught. (The more easily instructed are busy brushing their teeth, as pledged.) The independent-minded philosopher-saints are so sure of themselves that they often lose the discipline of any kind of peer review, formal or amateur. They end up opinionated, and alone.
