Enough has been said to show that the extreme and one-sided interpretations of the solar mythologists are due to a one-sided method. The philological has yielded splendid results; this the solar theorists have done; the historical yields results equally rich and fertile; this they have left undone. Language has given us the key to the kinship between the several members of the great body of Aryan myths; the study of the historical evolution of myths, the comparison of these, without regard to affinity of speech, will give us the key to the kinship between savage interpretation of phenomena all the world over. The mythology of Greek and Bushman, of Kaffir and Scandinavian, of the Red man and the Hindu, springs from the like mental condition. It is the uniform and necessary product of the human mind in the childhood of the race.
The belief that human beings could change themselves into animals has been already alluded to, but in view of its large place in the history of illusions, some further reference is needful.
Superstitions which now excite a smile, or which seem beneath notice, were no sudden phenomena, appearing now and again at the beck and call of wilful deceivers of their kind. That they survive at all, like organisms, atrophied or degenerate, which have seen "better days," is evidence of remote antiquity and persistence. Every seeming vagary of the mind had serious importance, and answered to some real need of man as a sober attempt to read the riddle of the earth, and get at its inmost secret.
So with this belief. It is the outcome of that early thought of man which conceived a common nature and fellowship between himself and brutes, a conception based on rude analogies between his own and other forms of life, as also between himself and things without life, but having motion, be they waterspouts or rivers, trees or clouds, especially these last, when the wind, in violent surging and with howling voice, drove them across the sky. Where he blindly, timidly groped, we walk as in the light, and with love that casts out fear. Where rough resemblances suggested to him like mental states and actions in man and brute, the science of our time has, under the comparative method, converted the guess into a certainty; not to the confirmation of his conclusions, but to the proof of identity of structure and function, to the demonstrating of a common origin, however now impassable the chasm that separates us from the lower animals.
