Peter Godfrey-Smith (b. 1965) is an Australian marine biologist and philosopher of science and professor at the University of Sydney. His best-selling book, Other Minds, revolutionized our understanding of cephalopods, suggesting that these animals represent "evolution's alternative experiment in the creation of highly developed intelligence." The author, an experienced scuba diver who regularly observes octopuses and cuttlefish in their natural habitat, is convinced that these organisms, infinitely distant from us, demonstrate outstanding cognitive abilities and a surprisingly high level of mental complexity.
