As a physician who undertook both formal and lifelong education joyfully and seriously, even now that I am retired, I really get what Janna Levin is talking about when she states that the truth is beautiful and is like that old comedy line: "Ah knows it when ah sees it." When I would see a patient, usually I knew the diagnosis before I could complete my examination or perform any testing. Mathematical symmetry is often associated with truth, and even with beauty of a person or a scene such as trees perfectly reflected in water stained black. Therefore, I agree that we often know the truth based upon experience and gut feeling, though we are still required to try to prove it.
