§ 24. Every moment we pass instantly from men's perceived actions to the motives implied by them; and so are led to formulate these actions in mental terms rather than in bodily terms. Thoughts and feelings are referred to when we speak of any one's deeds with praise or blame; not those outer manifestations which reveal the thoughts and feelings. Hence we become oblivious of the truth that conduct as actually experienced consists of changes recognized by touch, sight and hearing. This habit of contemplating only the psychical face of conduct, is so confirmed that an effort is required to contemplate only the physical face. Undeniable as it is that another's behavior to us is made up of movements of his body and limbs, of his facial muscles, and of his vocal apparatus, it yet seems paradoxical to say that these are the only elements of conduct really known by us, while the elements of conduct which we exclusively think of as constituting it, are not known but inferred. Here, however, ignoring for the time being the inferred elements in conduct, we have to deal with the perceived elements--we have to observe its traits considered as a set of combined motions. Taking the evolution point of view, and remembering that while an aggregate evolves, not only the matter composing it, but also the motion of that matter, passes from an indefinite incoherent homogeneity to a definite coherent heterogeneity, we have now to ask whether conduct as it rises to its higher forms, displays in increasing degrees these characters; and whether it does not display them in the greatest degree when it reaches that highest form which we call moral. § 25. It will be convenient to deal first with the trait of increasing coherence. The conduct of lowly-organized creatures is broadly contrasted with the conduct of highly-organized creatures in having its successive portions feebly connected. The random movements which animalcule makes have severally no reference to movements made a moment before; nor do they affect in specific ways the movements made immediately after. To-day's wanderings of a fish in search of food, though perhaps showing by their adjustments to catching different kinds of prey at different hours, a slightly-determined order, are unrelated to the wanderings of yesterday and to-morrow. But such more developed creatures as birds, show us in the building of nests, the sitting on eggs, the rearing of chicks, and the aiding of them after they fly, sets of motions which form a dependent series, extending over a considerable period. And on observing the complexity of the acts performed in fetching and fixing the fibres of the nest or in catching and bringing to the young each portion of food, we discover in the combined motions, lateral cohesion as well as longitudinal cohesion.
