In April 1963, Richard P. Feynman gave a series of remarkable lectures at the University of Washington in Seattle. These three consecutive talks were classic Feynman - full of wit and wisdom - but their subject matter was wholly unexpected: Feynman spoke not as a physicist but as a concerned fellow citizen, revealing his uncommon insights into the religious, political, and social issues of the day. Now, at last, these lectures have been published under the collective title The Meaning of It All. Here is Feynman on mind reading and the laws of probability and statistics; on Christian Science and the dubious effect of prayer on healing; and on human interpersonal relationships. Here is the citizen-scientist on the dramatic effect simple engineering projects could have on the plague of poverty; the vital role creativity plays in science; the conflict between science and religion; the efficacy of doubt and uncertainty in arriving at scientific truths; and why honest politicians can never be successful.
