This is Richard Feynman for the concerned layman. These three lectures, given in 1963, are Feynman's attempt to elucidate the proper role of science in the issues of the day. The first lecture discusses the value of skepticism and uncertainty in the field of science itself. The second lecture concerns what light the scientific method might shine on religious and political thought. The third, and most interesting, lecture is an extemporaneous talk on the 'unscientific age' of the 1960s. You may be surprised to discover how little things have changed since then. If you are a Feynman fan, or if you are concerned about the proper role of science and critical thinking in society, you will love this book. Well-written, non-technical, entertaining. A brilliant scientist displays a deep and abiding concern for social issues.
