13. Hence it is that, in primitive societies, the functions of legislator, judge, priest, and medicine man are all combined in one individual, the great medium of communication between man and the unknown, whose person is pre-eminently sacred. The laws that are to guide the community come in some mysterious manner through him from the higher powers. If two members of the clan are involved in a quarrel, he is appealed to to apply some test in order to ascertain which of the two is in the wrong--an ordeal that can have no judicial operation, except upon the assumption of the existence of omnipotent beings interested in the discovery of evil-doers, who will prevent the test from operating unjustly. Maladies and famines are unmistakeable signs of the displeasure of the good, or spite of the bad spirits, and are to be averted by some propitiatory act on the part of the sufferers, or the mediation of the priest-doctor. The remedy that would put an end to a long-continued drought will be equally effective in arresting an epidemic. 14. But who, and of what nature, are these supernatural powers whose influences are thus brought to bear upon every-day life, and who appear to take such an interest in the affairs of mankind? It seems that there are three great principles at work in the evolution and modification of the ideas upon this subject, which must now be shortly stated. 15. (i.) The first of these is the apparent incapacity of the majority of mankind to accept a purely monotheistic creed. It is a demonstrable fact that the primitive religions now open to observation attribute specific events and results to distinct supernatural beings; and there can be little doubt that this is the initial step in every creed. It is a bold and somewhat perilous revolution to attempt to overturn this doctrine and to set up monotheism in its place, and, when successfully accomplished, is rarely permanent. The more educated portions of the community maintain allegiance to the new teaching, perhaps; but among the lower classes it soon becomes degraded to, or amalgamated with, some form of polytheism more or less pronounced, and either secret or declared. Even the Jews, the nation the most conspicuous for its supposed uncompromising adherence to a monotheistic creed, cannot claim absolute freedom from taint in this respect; for in the country places, far from the centre of worship, the people were constantly following after strange gods; and even some of their most notable worthies were liable to the same accusation.
