Desire is a strange mental quality, and one very difficult to define strictly. It is linked with feeling on one side, and with will on the other. Feeling rises to desire, and desire rises to the phase of will and endeavors to express itself in action. Halleck says of Desire: "_It has for its object something which will bring pleasure or get rid of pain, immediate or remote, for the individual or for some one in whom he is interested. Aversion, or a striving to get away from something, is merely the negative aspect of desire._" Inclination in its various stages is aroused through the appeals to the feelings through the imagination. The feelings related to the several faculties are excited into action by a direct appeal to them through the imagination, and inclination or desired results. Appeal to Acquisitiveness will result in a feeling which will rise to inclination and desire for gain. Appeal to Approbativeness will act likewise in its own field. And so on through the list, each well-developed faculty being excited to feeling by the appropriate appeal through the imagination, and thus giving rise to Inclination which in turn strives to express itself in action through the will. In short, every man is a bundle of general desires, the nature and extent of which are indicated by his several faculties, and which result from heredity, environment, training, experience, etc. These desires may be excited toward a definite object by the proper emotional appeal through the imagination, and by suggestion. Desire _must_ be created or aroused before action can be had, or the will manifest in action. For, at the last, we do things only because we "want to," directly or indirectly. Therefore, the important aim of the Salesman is to make his prospect "want to." And in order to make him "want to" he must make him see that his proposition is calculated to "bring pleasure, or get rid of pain, immediate or remote, for the individual or for someone else in whom he is interested." In business, the words "profit and loss" may be substituted for "pleasure and pain," although really, they are but forms of the latter. But even when the prospect is brought to the stage of strong inclination or desire, he does not always move to gratify the same. Why is this? What other mental process interferes? Let us see as we pass on to the next stage of the purchase, known as:
