Man develops in terms of his environment. . He is largely what his surroundings make him. His survival is a matter of adaptation. This law of his development appears not alone in his relation to general physical conditions, but especially as responsive to his personal or spiritual environings. The power of personalities is most imperious - often unlimitedly so. We surrender unconsciously. This applies eminently to effects visible and audible. We unconsciously memorize and repeat. Adaptation develops into imitation. Attractive personalities are sure to fashion our movements and tones, and give them fixity. "I am part of all that I have met." Our ideals thus become working forces in ourselves.

Reference has already been made to the executive tendency of feeling and to the fact that knowledge is uniformly the precursor of emotion. There is no better way to classify the emotions than under the characteristic of our intellection which is the occasion, not to say the cause. Here has arisen the technical expression, "ideo-motor action." The motor effect, the action which results from our ideas, may not appear externally, it nevertheless exists. Ideas that enrage us prepare us for battle. How far they become executive depends upon our will. Let the will with its balance wheel of rationality be in abeyance, and ideas (as we have seen in case of the motive) will dominate; it may be with the surpassing potency of our sub-conscious organism.
