Sheldrake has shown in the past that he is not afraid to be labeled a rebel, thanks to his theory of morphic resonance, which suggests the following:
Natural systems, or morphic units, at all levels of complexity are animated, organized, and coordinated by morphic fields, which contain an inherent memory. Natural systems inherit this collective memory from all previous things of their kind by a process called morphic resonance, with the result that patterns of development and behavior become increasingly habitual through repetition.
Sheldrake believes that the "telepathy" between pets and humans, or between flocks of birds or schools of fish that move as a single organism, can be explained this theory. Sheldrake is less persuaded by anecdotes that suggest animal clairvoyance--warning of something in the near future--but refuses to disallow the possibility.
He accepts that the case histories he details so thoroughly in this book are anecdotal, but that makes them no less real; and as a scientist himself he sets up experimental conditions for studying this previously ignored phenomenon that show beyond any doubt that the phenomenon exists. He castigates traditional scientists for their refusal to countenance anything that doesn't fit in with their existing paradigms (or prejudices) and challenges them to come up with some more "acceptable" explanation--but none is forthcoming.
This fascinating book is a first attempt at a scientific investigation into a puzzling but quite common occurrence. One hopes that other scientists will follow Sheldrake's brave lead. --David V. Barrett
