Joy and suffering, pain and pleasure, the agreeable and disagreeable, play their considerable rôle in deliberation. Not, however, by way of a calculated estimate of future delights and miseries, but by way of experiencing present ones. The reaction of joy and sorrow, elation and depression, is as natural a response to objects presented in imagination as to those presented in sense. Complacency and annoyance follow hard at the heels of any object presented in image as they do upon its sensuous experience. Some objects when thought of are congruent to our existing state of activity. They fit in, they are welcome. They agree, or are agreeable, not as matter of calculation but as matter of experienced fact. Other objects rasp; they cut across activity; they are tiresome, hateful, unwelcome. They disagree with the existing trend of activity, that is, they are disagreeable, and in no other way than as a bore who prolongs his visit, a dun we can't pay, or a pestiferous mosquito who goes on buzzing. We do not think of future losses and expansions. We think, through imagination, of objects into which in the future some course of action will run, and we are _now_ delighted or depressed, pleased or pained at what is presented. This running commentary of likes and dislikes, attractions and disdains, joys and sorrows, reveals to any man who is intelligent enough to note them and to study their occasions his own character. It instructs him as to the composition and direction of the activities that make him what he is. To know what jars an activity and what agrees with it is to know something important about that activity and about ourselves.
