The Voluntary Mind has come to man in the course of evolution. It is not nearly so highly developed in the majority of people, as one might at first suppose. The majority of the race have the Involuntary Mind predominant, and are swayed more by feeling and desire than by intellect and will. Those in whom the Voluntary Mind is highly developed place the intellect over the feelings--the will over the desires. They submit their feelings to the inspection and approval of their intellect, and hold their desires in check by their will. We are in the habit of thinking of will as a something which acts--but in the majority of instances it is found to be employed in checking action of the desires--in holding back rather than in pushing forward. One of the chief duties of the developed will is that of inhibition, or restraint. And inhibition depends upon the decision of the judgment or intellect. The animal, savage, or child has but little power of this kind--the average individual has more than the child or savage but less than the developed individual--the developed individual has better self-control, and subordinates his emotional desires and feelings to his judgment and will, by inhibition or restraint. Every individual has both of these phases of mind--the Involuntary and Voluntary--the latter, however, being manifested in an infinite variety of degrees of development and power. Back of every Involuntary Mind is to be found the protecting Voluntary Mind--and likewise, back of every Voluntary Mind, no matter how strong it may be, there is ever the Involuntary Mind chafing under restraint and striving to escape its master's eye and express itself in its own way. And the master often relaxes its attention, or gets tired of its strenuous task, and then the hidden nature "plays while the cat's away." Perhaps the Salesman may be able to remember this classification of the two phases of the mind, by picturing them as _two partners_ engaged in business. The Salesman is trying to secure the trade of the firm. The one brother is an easy-going fellow, possessing curiosity and childish interest, capable of being "jollied," persuaded and coaxed, and apparently acting always from his momentary desires and feelings, desirous of appearing well in the eyes of others, and anxious to make a good impression, finding it easier to say "Yes," than "No"--easier to fall in with the wishes of others than to oppose them, being vain and complaisant. This partner's name is "Easyboy." The other partner is an entirely different sort of fellow. He is cold and calculating, manifesting very little feeling or emotion, submitting everything to his reason and judgment, not moved by prejudices for or against, driving a close bargain and resenting attempts to coax or drive him. His name is "Hardfellow."
