We call an election system just which distributes political influence according to individual ability and merit in state and community. We call a penal code just which, in spite of the manifold variety of misdemeanors and crimes, in spite of the seeming incomparability of the different punishments, has found a uniformly weighing system which parallels offences and punishments in accordance with public sentiment. We speak of a just gradation of salaries, of a just promotion of officers in every stock company, in every railroad, as well as in the army, and in the hierarchy of State officials. We speak of a just distribution of taxes, of a just gradation of wages, of just profits, of a just interest on loans. And always there is the same conception in the background: men are grouped and classified according to certain characteristics, qualities, deeds and accomplishments, descent and prosperity. Burdens and advantages should correspond to these classes.
The profit of an undertaking is said to be justly higher than the rate of interest, because a greater risk and an indemnity for labor are therein involved, both of which are foreign to interest. Interest on capital is just because the lender foregoes a possible profit or enjoyment, because the borrower is in a much worse position without this aid, and because for the service of the one a consideration from the other seems just. The high earnings of the well-known physician or lawyer are just, such is Adam Smith's argument, because of the large number who go to great expense in their studies; many have very small incomes; the chosen, able ones are thus in a manner compensated therefor.
Every house-wife, every servant girl, daily and hourly thinks this price and that unjust, and this always on the ground of comparisons, classifications and valuations. Most important, however, is the judgment of the justice or injustice of the condition of social classes in general.
Aristotle calls slavery just when master and slave are by nature as different as soul and body, as governing will and external instrument. Then, he says, it is a natural, intrinsically justified slavery; the external legal relation of society corresponds to human nature. Exactly the same can be said of all social gradations and classifications. We feel them to be just as far as we find them in accord with our observations of similar or dissimilar qualities of the classes in question. The public mind has never, apart from times of error and excitement, begrudged honor, riches and position to those whose actions, whose abilities correspondingly excelled. It found fault with the condition of the middle and lower classes whenever it observed that men of the same race, the same creed, the same community, were maltreated by their equals and were held in a subjection not corresponding to their education and merit. All class struggles of the past have arisen from these sentiments. The greatest politicians and popular leaders of all times, as well as the greatest kings and Caesars, placed themselves at the head of movements which, originating in oppressed, abused and maltreated classes, aspired, successfully or otherwise, to a removal of unjust social conditions. These class-struggles have often been only for political rights, for honors, or for marriage rights.
The essential element, however, was always an economic question, the distribution of incomes and wealth or the conditions and avenues to them, the possibilities of acquisition; for in the social struggle for life, economic existence is the most important factor.
And therefore the question always arises here also, whether that which is, is just. Is this restriction of trade, this or that institution touching the distribution of wealth, is this entire distribution of incomes just?
This question, indeed, is not always equally emphasized; the feelings which spring from the answer do not at all times equally influence the masses and single parties. The judgment, that a certain classification and distribution of incomes is just or unjust, is of course not the only one that is given about the social phenomenon in question. Nor is this judgment, even though thousands are agreed upon it, the only power which rules the distribution of incomes. But this judgment is the only psychological basis from which all demands for the right of equality have arisen. It is the basis of all individualism. From the standpoint of mankind there may be other demands; mankind and its interests demand sacrifices in the upper as well as in the lower ranks. The practical representatives of this standpoint in political life must, therefore, necessarily seek to combat or to weaken the conclusions resulting from this fundamental principle of individualism. And from their standpoint they are justified in so doing. But equally justified on the other hand is the standpoint of individualism; and it is this which demands justice, proportionality of duties and rights; it demands equality for equal, inequality for unequal men. The principle of civil, political and social equality will never have a firm foundation unless one seeks it in this connection. Every limitation of the principle of equality, other than that which is prompted by the qualities and merits of men, is arbitrary.
Material justice demands equal rights only in so far as it observes equal qualities, as it presumes the possibility of equal achievement and fulfillment of duties.
