Applying the law we dwelt upon under macrocosm that each involution presupposes an evolution, and each evolution an involution, we see that instinct is involved reason. What we call instinct in men or animals must therefore be involved, degenerated, voluntary actions, and voluntary actions are impossible without experience. Experience started that knowledge, and that knowledge is there. The fear of death, the duckling taking to the water and all involuntary actions in the human being which have become instinctive, are the results of past experiences. So far we have proceeded very clearly, and so far the latest science is with us. But here comes one more difficulty. The latest scientific men are coming back to the ancient sages, and as far as they have done so, there is perfect agreement. They admit that each man and each animal is born with a fund of experience, and that all these actions in the mind are the result of past experience. "But what," they ask, "is the use of saying that that experience belongs to the soul? Why not say it belongs to the body, and the body alone? Why not say it is hereditary transmission?" This is the last question. Why not say that all the experience with which I am born is the resultant effect of all the past experience of my ancestors?
