Such anomalous evidence, contradicting Darwinian evolution, catalyzed a global inquiry: “If we did not evolve from apes then where did we come from?”Human Devolution is Michael A. Cremo’s definitive answer to that question: “We did not evolve up from matter; instead we devolved, or came down, from the realm of pure consciousness, spirit.” Basing his response on modern science and the world’s great wisdom traditions, including the Vedic philosophy of ancient India, Cremo proposes that before we ask the question, “Where did human beings come from?” we should first contemplate, “What is a human being?” For much of the twentieth century, most scientists assumed that a human being is simply a combination of ordinary physical elements. In Human Devolution, Cremo says it is more reasonable to assume that a human being is a combination of three distinct substances: matter, mind, and consciousness (or spirit). He shows how solid scientific evidence for a subtle mind element and a conscious self that can exist apart from the body has been systematically eliminated from mainstream science by a process of “knowledge filtration.”
