Conduct, as actually known to us in perception, and not as interpreted into the accompanying feelings and ideas, consists of combined motions. On ascending through the various grades of animate creatures, we find these combined motions characterized by increasing coherence, increasing definiteness considered singly and in their co-ordinated groups, and increasing heterogeneity; and in advancing from lower to higher types of man, as well as in advancing from the less moral to the more moral type of man, these traits of evolving conduct become more marked still. Further, we see that the increasing coherence, definiteness, and heterogeneity, of the combined motions, are instrumental to the better maintenance of a moving equilibrium. Where the evolution is small this is very imperfect and soon cut short; with advancing evolution, bringing greater power and intelligence, it becomes more steady and longer continued in face of adverse actions; in the human race at large it is comparatively regular and enduring; and its regularity and enduringness are greatest in the highest. CHAPTER VI. THE BIOLOGICAL VIEW. § 30. The truth that the ideally moral man is one in whom the moving equilibrium is perfect, or approaches nearest to perfection, becomes, when translated into physiological language, the truth that he is one in whom the functions of all kinds are duly fulfilled. Each function has some relation, direct or indirect, to the needs of life: the fact of its existence as a result of evolution, being itself a proof that it has been entailed, immediately or remotely, by the adjustment of inner actions to outer actions. Consequently, non-fulfillment of it in normal proportion is non-fulfillment of a requisite to complete life. If there is defective discharge of the function, the organism experiences some detrimental result caused by the inadequacy. If the discharge is in excess, there is entailed a reaction upon the other functions, which in some way diminishes their efficiencies. It is true that during full vigor, while the momentum of the organic actions is great, the disorder caused by moderate excess or defect of any one function, soon disappears--the balance is re-established. But it is none the less true that always some disorder results from excess or defect, that it influences every function, bodily and mental, and that it constitutes a lowering of the life for the time being.
