In The Selfish Gene, Richard Dawkins proposed the concept of the meme as a unit of culture, spread by imitation. Now Dawkins himself says of Susan Blackmore:
Showing greater courage and intellectual chutzpah than I have ever aspired to, she deploys her memetic forces in a brave--do not think foolhardy until you have read it--assault on the deepest questions of all: What is a self? What am I? Where am I? ... Any theory deserves to be given its best shot, and that is what Susan Blackmore has given the theory of the meme.
Blackmore is a parapsychologist who rejects the paranormal, a skeptical investigator of near-death experiences, and a practitioner of Zen. Her explanation of the science of the meme (memetics) is rigorously Darwinian. Because she is a careful thinker (though by no means dull or conventional), the reader ends up with a good idea of what memetics explains well and what it doesn't, and with many ideas about how it can be tested--the very hallmark of an excellent science book. Blackmore's discussion of the "memeplexes" of religion and of the self are sure to be controversial, but she is (as Dawkins says) enormously honest and brave to make a connection between scientific ideas and how one should live one's life. --Mary Ellen Curtin
