The lower animals are of course conscious of the bodies, and their wants, feelings, emotions, desires, etc., and their actions are in response to the animating impulses coming from this plane of consciousness. But it stops there. They "know," but they do not "know that they know"; that is, they have not yet arrived at a state in which they can think of themselves as "I," and to reason upon their thoughts and mental operations. It is like the consciousness of a very young child, which feels and knows its sensations and wants, but is unable to think of itself as "I," and to turn the mental gaze inward. In another book of these series we have used the illustration of the horse which has been left standing out in the cold sleet and rain, and which undoubtedly feels and knows the unpleasant sensations arising therefrom, and longs to get away from the unpleasant environment. But, still, he is unable to analyze his mental states and wonder whether his master will come out to him soon, or think how cruel it is to keep him out of his warm comfortable stable; or wonder whether he will be taken out in the cold rain again tomorrow; or feel envious of other horses who are indoors; or wonder why he is kept out cold nights, etc., etc. In short, the horse is unable to think as would a reasoning man under just the same circumstances. He is aware of the discomfort, just as would be the man; and he would run away home, if he were able, just as would the man. But he is not able to pity himself, nor to think about his personality, as would a man--he is not able to wonder whether life is worth the living, etc., as would a man. He "knows" but is not able to reflect upon the "knowing."

In the above illustration, the principal point is that the horse does not "know himself" as an entity, while even the most primitive man is able to so recognize himself as an "I." If the horse were able to think in words, he would think "feel," "cold," "hurt," etc., but he would be unable to think "_I_ feel; _I_ am cold; _I_ am hurt," etc. The thought "I" would be missing.

It is true that the "I" consciousness of the primitive man was slight, and was but a degree above the Physical Consciousness of the higher apes, but nevertheless it had sprung into being, never again to be lost. The primitive man was like a child a few years old--he was able to say "I," and to think "I." _He had become an individual soul._

And this individual soul inhabited and animated a body but little removed from that of an ape. But this new consciousness began to mould that rude body and the ascent was begun. Each generation showed a physical improvement over that of the preceding one, according to the lines of physical evolution, and as the developing soul demanded more perfect and developed bodies the bodies were evolved to meet the demand, for the mental demand has ever been the cause of the physical form.

The soul of the primitive man reincarnated almost immediately after the death of the physical body, because the experiences gained were mostly along the lines of the physical, the mental planes being scarcely brought into play, while the higher and spiritual faculties were almost entirely obscured from sight. Life after life the soul of the primitive man lived out in rapid succession. But in each new embodiment there was a slight advance over that of the previous one. Experience, or rather the result of experiences, were carried over, and profited by. New lessons were learned and unlearned, improved upon or discarded. And the race grew and unfolded.

After a time the number of advancing souls which had outstripped their fellows in progress became sufficiently large for sub-races to be formed, and so the branching off process began. In this way the various races and types were formed, and the progress of Mankind gained headway. At this point we may as well consider the history of the Races of Mankind, that we may see how the great tide-wave of Soul has ever pressed onward, marking higher and still higher stages of progress, and also how the various minor waves of the great wave pushed in and then receded, only to be followed by still higher waves. The story is most interesting.
