The Rational Optimist

Science journalist Ridley believes there is a reason to be optimistic about the human race, and he defies the unprecedented economic pessimism he observes. His book is about the rapid and continuous change that human society experiences, unlike any other animal group. Ideas needed to meet and mate for culture to turn cumulative, and “there was a point in human pre-history when big-brained, cultural, learning people for the first time began to exchange things with each other and that once they started doing so, culture suddenly became cumulative, and the great headlong experiment of human economic ‘progress’ began.” Participants in the exchanges improved their lives by trading food and tools. Ridley believes it is probable that humanity will be better off in the next century than it is today, and so will the ecology of our planet. He dares the human race to embrace change, be rationally optimistic, and strive for an improved life for all people
