On the whole, then, we seem to be justified in inferring that in many parts of the world the king is the lineal successor of the old magician or medicine-man. When once a special class of sorcerers has been segregated from the community and entrusted by it with the discharge of duties on which the public safety and welfare are believed to depend, these men gradually rise to wealth and power, till their leaders blossom out into sacred kings. But the great social revolution which thus begins with democracy and ends in despotism is attended by an intellectual revolution which affects both the conception and the functions of royalty. For as time goes on, the fallacy of magic becomes more and more apparent to the acuter minds and is slowly displaced by religion; in other words, the magician gives way to the priest, who, renouncing the attempt to control directly the processes of nature for the good of man, seeks to attain the same end indirectly by appealing to the gods to do for him what he no longer fancies he can do for himself. Hence the king, starting as a magician, tends gradually to exchange the practice of magic for the priestly functions of prayer and sacrifice. And while the distinction between the human and the divine is still imperfectly drawn, it is often imagined that men may themselves attain to godhead, not merely after their death, but in their lifetime, through the temporary or permanent possession of their whole nature by a great and powerful spirit. No class of the community has benefited so much as kings by this belief in the possible incarnation of a god in human form. The doctrine of that incarnation, and with it the theory of the divinity of kings in the strict sense of the word, will form the subject of the following chapter. VII. Incarnate Human Gods
