3. The judgment of energy-equivalence, then, defines the inhibiting economic aspect of the means, and moreover defines it for the means as subdivided and set apart for a schedule of uses if this was the form of the past adjustments to which reference is made. The problem of the third stage of the process is that of "bringing subject and predicate together," as we have elsewhere expressed it--that is, of determining, in the light of the economic character of the means as just ascertained, what measure of satisfaction, if any, may be accorded to the new and as yet undefined desire. The new disposition of the means, if one is to be made, must bring to the "energetic" self a degree of furtherance and development which shall be sensibly as great as would come from the established method of consumption. The means, as economic, are means to the conservation of the old adjustment, and any new disposal of them or of any portion of them for a full or partial execution of the new purpose must make out at least as good a case. It must appear that the new disposition is not only physically possible, but also economically necessary in the light of the same principle of expansion of the self as sanctioned the disposition now in force. It must make the self in some way more efficient--whether more strong and symmetrical in body, more skilled in work, more clear of brain, or more efficient in whatever other concrete way may be desired. Psychologically the sanction of any course of action which is taken as evidence of conformity to the general rule thus inadequately stated is the more or less strong sense of "relaxation" of attentive strain which comes with the shift of attention, in the final survey, from means to end. We may accordingly, for the sake of greater definiteness, restate in the following terms the process which has just been sketched: The ends in conflict at the outset are ends which do not sensibly bear upon each other through their dependence upon a common fund of psychical capacities or energies. They are related in the agent's experience solely through their dependence upon a common stock of physical means, and they do not therefore admit of adjustment through the ethical type of process. The economic process consists essentially of a revival in imagination of the experiences accompanying the former disposition of the means and a re-enforcement by these of the means in their adherence to that former and still recognized disposition. If an adapted form of the new end can be imagined which will mediate a like experience of relaxation when the attention shifts from the means, thus emotionally re-enforced in their economic status, to the end as thus conceived, the means will be recognized as economically redisposable. Thus the method of valuation of the means makes possible, through appeal to the sensibly invariable experience of relaxation or assurance in the outcome of judgment, a co-ordination of disparate ends which the ethical method
