Although it appears that our paleo ancestors inhabiting temperate and tropical ecosystems had no modern diet-related diseases, they did suffer dis-eases, and universally had "medicine men," also known among anthropologists as "shamans." As a medical system, shamanism maintains that many apparently physical dis-eases have spiritual causes. Indigenous/shamanic tribal cultures "believe" that spirits exist and play roles in individual, tribal, and ecological health. Shamanic interventions address traumas affecting the soul/spirit through direct interaction with the spiritual realm, achieved through altered states of consciousness that provide entrance to a non-ordinary reality. All this talk of spirits certainly makes anxiety for modern "scientific" atheists and Judeo-Christian religionists alike. The former will dismiss such talk as mumbo-jumbo without empirical basis, a threat to rationality and logic. They will tend to dismiss shamanism as dealing with non-existent "supernatural" entities. The latter believe that for some odd reason the One True God chose to reveal himself and the Rules for the Right Way of Life only to the members of several middle Eastern desert tribes, leaving everyone else in the dark. They also believe that this God gave these chosen people not only the right but the duty to convert all other tribes to their faith and way of life, if not by persuasion then by force. These people call non-believers by various names like heretic, infidel, heathen, pagan, and so on, and have called shamanic culture "demonic." In either case, shamanism directly competes with the "authorities." Atheists may consider shamans a threat to the authority of "reason," science, and scientists, and religionists certainly consider shamans a threat to the authority of their faith, dogma, and priests. Shamanism comes from non-hierarchical tribal culture in which no one has ultimate authority over another, and thus it conflicts with civilization and all types of authority....read more...
