By way of conclusion it may be helpful to consider certain general truths in the field of anthropology and mental evolution, upon which the illustrations we have been considering have a bearing. We have seen what a widely extended genus the analogical argument compasses; and yet, if we were to include under this head certain closely allied and yet distinguishable forms of thought, it would be much wider still. I refer particularly to the use of metaphor and symbolism, which, like the children's make-believe with their dolls or fairies, is none the less on the boundary line between the real and the fictitious. Myth equally readily passes from the unconscious to the conscious stage, and much of what is plausibly interpreted as an argument by analogy, seems equally well an intentional use of symbolism and myth. That savages, at least in all but the lower stages, appreciate the use of myth is beyond all doubt. Primitive ceremonials, as also primitive explanations of the changes of nature, are full of symbolisms, which involve the same mental habit, whose products in the domain of analogy have been portrayed. This mythological instinct, Mr. Tylor well says, "belongs to that great doctrine of analogy from which we have gained so much of our apprehension of the world around us. Distrusted as it now is by severer science for its misleading results, analogy is to us still a chief means of discovery and illustration, while in earlier grades of education its influence was all but paramount. Analogies which are but fancies to us were to men of past ages reality. They could see the flame licking its yet undevoured prey with tongues of fire, or the serpent gliding along the sword from hilt to point; they could see a live creature gnawing within their bodies in the pangs of hunger; they heard the voices of the hill-dwarfs answering in the echo, and the chariot of the heaven god rattling in thunder over the solid firmament. Men to whom these were living thoughts had no need of the schoolmaster and his rules of composition, his injunctions to use metaphor cautiously and to take care to make all similes consistent."
