But, though all the race have these in common, yet we can not but observe an almost endless variety of human character, resulting from the diverse _proportions_ and _combinations_ of these several faculties. These constitutional differences may be noticed, first, in regard to the intellectual powers. Some minds are naturally predisposed to exercise the reasoning powers. Others, with precisely the same kind of culture, have little relish for this, and little power of appreciating an argument. In other cases, the imagination seems to be the predominating faculty. In other minds there seems to be an equal balance of faculties, so that no particular power predominates. Next we see the same variety in reference to the susceptibilities. In some minds, the desire for love and admiration is the predominating principle. In others, the love of power takes the lead. Some are eminently sympathizing. Others have a strong love of rectitude, or natural conscience. In some, the principle of justice predominates. In others, benevolence is the leading impulse. Finally, in regard to the power of volition, as has been before indicated, there are some that possess a strong will that is decisive and effective in regulating all specific volitions, while others possess various and humbler measures of this power. According to the science of Phrenology, some of these peculiarities of mind are indicated by the size and shape of different portions of the brain, and externally indicated on the skull. That these differences are constitutional, and not the result of education, is clear from the many facts showing that no degree of care or training will serve to efface these distinctive traits of the mind. To a certain degree they may be modified by education, and the equal balance of the faculties be promoted, but never to such a degree as to efface very marked peculiarities. In addition to the endless diversities that result from these varied proportions and combinations, there is a manifest variety in the grades of mind. Some races are much lower in the scale of being every way than others, while the same disparity exists in individuals of the same race. The wisdom and benevolence of this arrangement is very manifest when viewed in reference to the interests of a commonwealth. Where some must lead and others follow, it is well that some have the love of power strong, and others have it less. Where some must be rulers, to inflict penalties as well as to apportion rewards, it is well that there be some who have the sense of justice as a leading principle. And so in the developments of intellect. Some men are to follow callings where the reasoning powers are most needed. Others are to adopt pursuits in which taste and imagination are chiefly required; and thus the varied proportions of these faculties become serviceable.
