I’m still in southern California, and have had no time for writing today. So here is some more Richard Feynman for you. This clip is about ten minutes long, and unfortunately begins in mid-sentence; of particular interest, however, is the section from about 5:15 on, in which he talks about the built-in uncertainty of science, the nature of doubt, and how hard it is for someone constituted as he is simply to “believe”.
Feynman articulates my own feelings about all of this almost exactly. How sad that he is gone.
