The first three main divisions will be given over to establishing the objectivity of content and function of judgments of value. The fourth division will present a detailed analysis of the two types of judgment of value, the ethical and economic, defining them and relating them to each other, and correlating them in the manner just suggested with judgment of the physical type. After considering, in the fifth part, certain general objections to the positions thus stated, we shall proceed in the sixth and concluding division to define the function of the consciousness of value in the economy of life.[107] I The system of judgments which defines what one calls the objective order of things is inevitably unique for each particular individual. No two men can view the world from the standpoint of the same theoretical and practical interests, nor can any two proceed in the work of gaining for themselves knowledge of the world with precisely equal degrees of skill and accuracy. Each must be prompted and guided, in the construction of his knowledge of single things and of the system in which they have their being, by his own particular interests and aims; and even when one person in a measure shares in the interests and aims of another, the rate and manner of procedure will not be the same for both, nor will the knowledge gained be for both equally systematic in arrangement or in interrelation of its parts. Each man lives in a world of his own--a world, indeed, identical in certain fundamental respects with the worlds which his fellow-men have constructed for themselves, but one nevertheless necessarily unique through and through because each man is a unique individual. There is, doubtless, a "social currency" of objects which implies a certain identity of meaning in objects as experienced by different individuals. The existence of society presupposes, and its evolution in turn develops and extends, a system of generally accepted objects and relations. Nevertheless, the "socially current object" is, as such, an abstraction just as the uniform social individual is likewise an abstraction. The only concrete object ever actually known or in any wise experienced by any person is the object as constructed by that person in accordance with his own aims and purposes, and in which there is, therefore, a large and important share of meaning which is significant to no one else.
