by Carl Sagan (2006). Sagan’s 1985 Gifford Lectures on Natural Theology. Such a superb, clear and compelling thinker and writer. The actual topic is more on natural knowledge but Sagan touches on questions of why people believe, the weird and highly idiosyncratic nature of beliefs, the question of God, what can science confidently assert (plus, of course, on Sagan’s signature themes of astronomy, SETI and nuclear winter). An excellent job and a superbly edited book. I recommend it highly.
