Michael Shermer: Science needs its poets, and Alan Lightman is the perfect amalgam of scientist (an astrophysicist) and humanist (a novelist who’s also a professor of the practice of humanities at M.I.T.), and his latest book, Searching for Stars on an Island in Maine, is an elegant and moving paean to our spiritual quest for meaning in an age of science. The book consists of 20 tightly composed essays on a variety of topics (stars, atoms, truth, transcendence, death, certainty, origins and so on) with a single narrative thread running through them: the search for something deeper in the materialist worldview of the scientist.
