And now, on studying the doings of the highest of mammals, mankind, we not only find that the adjustments of acts to ends are both more numerous and better than among lower mammals, but we find the same thing on comparing the doings of higher races of men with those of lower races. If we take any one of the major ends achieved, we see greater completeness of achievement by civilized than by savage; and we also see an achievement of relatively numerous minor ends subserving major ends. Is it in nutrition? The food is obtained more regularly in response to appetite; it is far higher in quality; it is free from dirt; it is greater in variety; it is better prepared. Is it in warmth? The characters of the fabrics and forms of the articles used for clothing, and the adaptations of them to requirements from day to day and hour to hour, are much superior. Is it in dwellings? Between the shelter of boughs and grass which the lowest savage builds, and the mansion of the civilized man, the contrast in aspect is not more extreme than is the contrast in number and efficiency of the adjustments of acts to ends betrayed in their respective constructions. And when with the ordinary activities of the savage we compare the ordinary civilized activities--as the business of the trader, which involves multiplied and complex transactions extending over long periods, or as professional avocations, prepared for by elaborate studies, and daily carried on in endlessly varied forms, or as political discussions and agitations, directed now to the carrying of this measure and now to the defeating of that--we see sets of adjustments of acts to ends, not only immensely exceeding those seen among lower races of men in variety and intricacy, but sets to which lower races of men present nothing analogous. And along with this greater elaboration of life produced by the pursuit of more numerous ends, there goes that increased duration of life which constitutes the supreme end.
