The first collection of essays from renowned scientist and best-selling author Richard Dawkins is an enthusiastic declaration, a testament to the power of rigorous scientific examination to reveal the wonders of the world. In these essays Dawkins revisits the meme, the unit of cultural information that he named and wrote about in his groundbreaking work The Selfish Gene. Here also are moving tributes to friends and colleagues, including a eulogy for novelist Douglas Adams, author of The Hitchhiker's Guide to the Galaxy; correspondence with the evolutionary biologist Stephen Jay Gould; and visits with the famed paleoanthropologists Richard and Maeve Leakey at their African wildlife preserve. The collection ends with a vivid note to Dawkins's ten-year-old daughter, reminding her to remain curious, to ask questions, and to live the examined life.
