1. The value of consumption goods is derived from the pleasurable psychic impressions which they aid to produce, and these psychic effects constitute the psychic income. The objective income is sometimes called the "real" income, but certainly it is not income in the most essential sense. Things outside of men cannot be feelings, they can only call out or occasion feeling, and it is the attainment of pleasurable conditions in mind or soul that is the aim of all economic activity. Material income and immaterial income are both re-lated to and reducible to psychic income. Some portions at-least of the objective incomes of goods are continually by use becoming subjective incomes of enjoyment. Men talk of material income as consisting of bushels of wheat, head of cattle, etc., and of immaterial income as the uses that durable goods yield directly or that men perform for each other, e.g., those of the singer, physician, teacher, judge - all services that do not take on material form. There was a long-standing dispute in economic literature regarding the difference between productive and unproductive labor. Productive labor was said to be that which embodied itself in abiding material form. The distinction led to some peculiar puzzles and paradoxes. The bartender mixing drinks, adds to the value of those ingredients; in a minute that value is dissipated. According to the distinction in question, he is a productive laborer because his services are embodied in material form, whereas the lecturer is regarded as an unproductive laborer because the results of his labor are not embodied in material form. But whether or not the service has for a moment embodied itself in material form is of no essential economic import. The presence of the waiter is as essential to the well-served dinner as are the polished silver and china, or as the well-cooked food. The distinction in question is not now made by economists, all labor that contributes to value being regarded as productive. But a similar distinction is inconsistently preserved by many writers in the case of material things. A building used as a factory is called productive, but used by the owner as a dwelling it is called unproductive because the service it renders does not appear in material form. But the use of the house, or that of land for a school ground or campus, secures a certain gratification, an immaterial good. Consistency requires that the services of men and the use of material things be judged by their psychic results, the question whether the service takes on a material or an immaterial form being disregarded.

Gratification the test of psychic income.

All sources of income are productive.

All wealth is logically related to psychic income.

2. Only those things and actions that are in some causal relation to gratifications can have value to man. This proposition of theory is demonstrated every hour in practical life. The business man always is trying to trace a causal relation between things that do not and cannot themselves directly satisfy wants, and things that do. The vineyard has no value to Tantalus, unable to reach its fruit. A captive, chained to a rock, attaches value only to the things within his reach. Men living in savagery and ignorance starve amid the possibilities of plenty. Chained by their ignorance and improvidence to a little spot of earth, they do not see clearly, either in time or space, the economic relations about them.

Values of things distant in time.

3. Man's foresight and knowledge enable him to think of many periods at once, and thus his felt dependence on goods extends over a series of future productive agents. In order to simplify the problem, we have spoken of the economic man as living only in and for the moment. If he had no more knowledge, memory, or imagination than is necessary to compare goods here, only present goods could have value to him. Even the higher animals, and much more the savages, rise above that level of improvidence. With increased intelligence the economic life of man expands, and he attaches importance to things which at the present moment have not, and cannot have, the slightest influence on his immediate gratification. The extension of man's view works a momentous change in his economic estimates. Of the thousands of forms of matter in the world, only a comparatively few ever will make an immediate gratifying impression on man's senses. But many of them are so connected in his thought by chains of association with pleasures or uses, that almost instinctively and most intensely he attaches an importance to them. In most cases it would require close thought to see that the service attributed directly to them was but a reflection of that performed by some other good. Thus, more and more, the estimates placed by men on goods come to depend on knowledge and foresight, and not on immediate impressions and feelings.

4. Things are causally related in varying degrees to the psychic income, and have value only as their relation is known and felt. The explanation of value is not complete till value has been traced back to its source in gratification Often the complex nature of the problem is ignored. If one discusses the trading of a bushel of grain, to be used by a hungry man for food, for a sheep to be kept for breeding, or for wool to be made into cloth next year, he may overlook the difference in the grade of wants compared. In this case, a gratification of the present moment is compared with a gratification of a very different kind at a future time. The problem involved is complex because of differences in time, in place, and in the nature of the want-gratifiers. The student should endeavor to reduce the problem of value to its simplest form by considering first the exchange, at the present moment, of immediately enjoyable goods. The logical starting-point in the theory of value is in those goods that are in closest touch with feeling, and on this basis may be built up an explanation of values in which reason and forethought have a greater part. Starting from the proposition that psychic income is the foundation of all values, we shall go on, however, to trace causes that give value to all the physical agents, and to the most indirect of want-gratifiers.

Note

The phrase "psychic income," used here for the first time, expresses a conception long neglected, but essential to the advancement of psychological economics. The idea has been recognized in the writings of Edwin Cannan, Irving Fisher, W. M. Daniels, and perhaps of late by others. It was discussed by the author in the Quarterly Journal of Economics, Vol. XV, pp. 19-30, especially pp. 25-26, in an article called "Recent Discussion of the Capital Concept" (November, 1900).
