evolutionist ought to have no difficulty in explaining these terrors, and the scenery that provokes them, as relapses into the consciousness of the cave men, a consciousness usually overlaid in us by experiences of a more recent date." Instinctive emotion manifests as an impulse arising from the dim recesses of the feeling or emotional nature--an incentive toward a dimly conscious end. It differs from the almost purely automatic nature of certain forms of reflex process, for its beginning is a feeling arising from the subconscious regions, which strives to excite an activity of conscious volition. The feeling is from the subconscious, but the activity is conscious. The end may not be perceived in consciousness, or at least is but dimly perceived, but the action leading to the end is in full consciousness. Instinct is seen to have its origin in the past experiences of the race, transmitted by heredity and preserved in the race memory. It has for its object the preservation of the individual and of the species. Its end is often something far removed in time from the moment, or the welfare of the species rather than that of the individual; for instance, the caterpillar providing for its future states, or the bird building its nest, or the bees building cells and providing honey for their successors, for very few bees live to partake of the honey which they have gathered and stored--they are animated by "the spirit of the hive." The most elementary forms of the instinctive emotions are those which have to do with the preservation of the individual, his comfort, and personal physical welfare. This class of emotions comprises what are generally known as purely "selfish" feelings, having little or no concern for the welfare of others. In this class we find the emotional feelings which have to do with the satisfaction of hunger and thirst, the securing of comfortable quarters and warm clothing, and the spirit of combat and strife arising from the desire to obtain these. These elemental feelings had their birth early in the history of life, and indeed life itself depended very materially upon them for its preservation and continuance. It was necessary for the primitive living thing to be "selfish." When man appeared, only those survived who manifested these feelings strongly; the others were pushed to the wall and perished. Even in our civilization the man below the average in this class of feelings will find it difficult to survive. CHAPTER XIII. The Passions.
