The mental processes are the same whether here or on the ground of actual law. Everywhere it is in the main traditional standards which govern our judgment. These traditional and conventional standards are the historical precipitate of the conception of justice of hundreds of millions of men, on whose shoulders we stand. Through these traditions the seemingly irregular, the casual and individual takes firm body and lasting form in spite of constant transformations and renewals.
From this standpoint we can easily refute the naive objection that there is no way to apply the conception of the just to economic matters, because, it is said, incomparable quantities and qualities are in question, the different kinds of work, the functions of the employer and the day-laborer being immeasurable by any common standard. They forget that the formation of prices in the market equalizes that which is seemingly incomparable, as, for instance, an edition of Goethe and a bottle of champagne;that in every penal code two things which appear to be still more heterogeneous, a fine of so and so much money and a day's imprisonment are in a fixed ratio according to a conventional standard. Everywhere in the questions of prices and of law the traditional and conventional judgment, that this is to be called equal and not that, is fundamental. Only should we have to begin every moment to form our judgments anew would this objection be reasonable. As things are, the fact remains that the average earnings of the employer; compared to the wages of the laborer, can be raised or lowered by a change in demand and supply within such an economic organization as exists to-day; that independently thereof, in consequence of traditional standards on the one hand and of the modern sentiments and ideals on the other, this change, as soon as it has reached a certain extent, will appear just or unjust.
And whenever these and similar questions are discussed, when opinions differ about them, the controversy is not, as a rule, between those who wish to apply the categories of justice to these phenomena, and those who deny their applicability; but the struggle is between older and traditional standards of judgment and new ones, the ideals of the eighteenth century with those of the nineteenth; the struggle is between a cruder conception of right and a more refined one, between ideals whose realization is to-day impossible and those that are attainable through the customs and the law of our age; finally ideal conceptions of justice which have already been co-ordinated with other not less justified ideals are arrayed against those which have chosen principles of justice exclusively for their battle-cry.
And just because this struggle never ceases there is, as we have seen above, no simple, universally intelligible, familiar and applicable formula of justice. The conceptions in question may all be reduced to this fundamental idea: everyone according to his merit, "suum cuique"; but the possible application of this rule is always different according to the possibility of innumerable conceptions of value, estimations, groupings and classifications. The abstract pretension, for example, that in labor or even in handiwork rests the unique standard of justice is in equal right with the other pretense that talent, virtue or even the human face must be taken into account. In certain spheres and in respect to certain aims only will one formula or the other gradually prove its justification and thus gain recognition.
But what is it that gives the final decision in this contest of opinions? Is it logical reasoning? Apparently not, or at least not primarily. Much as in the struggle for public and social institutions, all kinds of logical reasons for the justice of a cause are appealed to, they seldom convince and always seem more or less flat. At least they do not convince the opponent, although they are capable of inciting their followers to enthusiastic and desperate struggles. And this is natural. They are not logical decisions. Whether they be traditional standards of valuation, whose immemorial age or even divine origin impresses our spirits or newer conceptions, which by the power of passion inflame the disciples of a school, a party, the members of a class or a people, the final decision rests with the heart, with the innermost centre of human soul and mind.
This explains the vast possibility of error, of delusion, of vehement passions. Ideals of justice may appear in the most distorted forms, in its name the most insane as well as the highest and holiest things are demanded. Long struggles are often necessary to purify concepts of their errors and to develop the ideal in its purity. But at the same time the inward connection between the conceptions of the "just" and the depth of human emotions explains the magic power of their effect. That which moves the inmost heart dominates the wills, the egoism, inspires deeds of valor, carries away the individual and millions to deeds and sacrifices. Hence the mystery that a political platform, an economic contrivance, only influences where it seems an outcome of justice. Hence the involuntary tendency to appeal to justice in every discussion. Hence also the fact that the same theory which proposes a demand of justice as its consequence often is made by individuals, but repudiated by public opinion; and then suddenly with irresistible elementary force it takes hold of the masses, leads them on new paths, radically influences legislation and puts a changed stamp on whole epochs.
