To all this, Anthropology will put an end, for it will give to each a definite conception of the full normal development of humanity, and of the organization or brain development by what it is sustained. To those who fall far short of that development, it gives the means of a definite measurement of the defect, and shows by cranioscopy and psychometry what is to be done in self-culture, as clearly as we learn in the gymnasium what muscles need greater development. The desire for such improvement is often absent when it is most needed. A vast multitude of inferior people are perfectly content with themselves in a selfish life, wholly absorbed in providing for their own wants, or, if possessed of wealth, using it only in selfishness and ostentation,--content in believing themselves as good as their neighbors, doing nothing to benefit society, unless under the coercion of public opinion, leading such lives that the world is certainly no better, and perhaps a little worse, for their advent. A very different class, who are more apt to profit by anthropology is composed of those in whom there is a decided predominance of good. In some cases they are deficient in selfish and combative energy, do not know how to assert their rights, are credulous and confiding. Children of that character if reared by timid and over-fond parents, are deprived of the rough contact with society that is necessary to their development. There are many whom the lack of self-confidence, the lack of ambition, and lack of business energy condemn to an obscure life, when their intellectual capacities would fit them for an influential position. A kind but mistaken system of training confirms the defect, and dooms them to an inefficient life, or a stern system of repression deprives them of all self-confidence and energy. Millions of good women are victimized in this manner. This amiable class are amenable to instruction, but are often by their easy credulity, induced to yield to unworthy teachers, or to the guidance of unsound but pretentious or delusive literature. They lack in the energy of criticism which might protect them from error. Throughout the whole course of education, from infancy to manhood, Anthropology may be an ever-present monitor, warning against excesses, against failures, against errors of opinion, while urging the cultivation of our feebler faculties as the gymnastic teacher urges the cultivation of the feebler muscles. Unaware of their errors, many would resent all such criticism, but the science which cannot help them, because they will have none of it, will enable us to understand them correctly and know how to deal with them.
