The shamans dressed well and usually had a number of wives; they were the original aristocracy, being exempt from all tribal restrictions. They were very often of low-grade mind and morals. They suppressed their rivals by denominating them witches or sorcerers and very frequently rose to such positions of influence and power that they were able to dominate the chiefs or kings.

Primitive man regarded the shaman as a necessary evil; he feared him but did not love him. Early man respected knowledge; he honored and rewarded wisdom. The shaman was mostly fraud, but the veneration for shamanism well illustrates the premium put upon wisdom in the evolution of the race.

Since ancient man regarded himself and his material environment as being directly responsive to the whims of the ghosts and the fancies of the spirits, it is not strange that his religion should have been so exclusively concerned with material affairs. Modern man attacks his material problems directly; he recognizes that matter is responsive to the intelligent manipulation of mind. Primitive man likewise desired to modify and even to control the life and energies of the physical domains; and since his limited comprehension of the cosmos led him to the belief that ghosts, spirits, and gods were personally and immediately concerned with the detailed control of life and matter, he logically directed his efforts to winning the favor and support of these superhuman agencies.

Viewed in this light, much of the inexplicable and irrational in the ancient cults is understandable. The ceremonies of the cult were primitive man's attempt to control the material world in which he found himself. And many of his efforts were directed to the end of prolonging life and insuring health. Since all diseases and death itself were originally regarded as spirit phenomena, it was inevitable that the shamans, while functioning as medicine men and priests, should also have labored as doctors and surgeons.

The primitive mind may be handicapped by lack of facts, but it is for all that logical. When thoughtful men observe disease and death, they set about to determine the causes of these visitations, and in accordance with their understanding, the shamans and the scientists have propounded the following theories of affliction:

1. Ghosts—direct spirit influences. The earliest hypothesis advanced in explanation of disease and death was that spirits caused disease by enticing the soul out of the body; if it failed to return, death ensued. The ancients so feared the malevolent action of disease-producing ghosts that ailing individuals would often be deserted without even food or water. Regardless of the erroneous basis for these beliefs, they did effectively isolate afflicted individuals and prevent the spread of contagious disease.

2. Violence—obvious causes. The causes for some accidents and deaths were so easy to identify that they were early removed from the category of ghost action. Fatalities and wounds attendant upon war, animal combat, and other readily identifiable agencies were considered as natural occurrences. But it was long believed that the spirits were still responsible for delayed healing or for the infection of wounds of even “natural” causation. If no observable natural agent could be discovered, the spirit ghosts were still held responsible for disease and death.
