Starting with this discovery, Hudson, after defining the dual character of mind, introduces two propositions, namely: that the subjective mind is constantly amenable to control by suggestion, and that the subjective mind is incapable of inductive reasoning. Man in hypnotic state has invariably given sufficient evidence to show that the subjective mind accepts, without hesitation or doubt, every statement that is made to it. With regard to this Law of Suggestion it is well to remember that, while the subjective mind is invariably and constantly swayed by suggestion, and is capable of offering no resistance except that which has been communicated to it by the objective mind, or which is inherent in its nature, the objective mind, on the other hand, is perpetually assailed by extrinsic suggestion, its capacity for resistance being in proportion to the dominant quality and development of the mind-whole. The objective mind, it will therefore be seen, is potentially selective, that is to say, the measure of its quality is its capacity to select at will intellectual nourishment from the whole range of humanity and nature, free from the oppression of its psychic environment. The rare combination of this intellectual fastidiousness with a super-sensibility is the mark of true genius. Every one is conscious that at times we become aware of impulses, inclinations and concepts which seem to form no part of our thinking or waking minds; they seem to come from the depths of our souls in response to some vital need of our existence. When the tendency appears to be hereditary we call these promptings instincts[48] and consider it right to suppress them or hold them in check. We do not resign ourselves wholesale to unbridled licentiousness or anger because the reproductive instinct and pugnacity are inherent in our nature; on the contrary, we realize that our best interests lie in self-control. If, on the other hand, the impulse is less easily accounted for, if, maybe, the message of our souls runs counter to our normal instincts, our interests or reason, we are apt to assume that the impulse emanates from outside our nature and must have, many of us think, a supernatural or Divine origin. It may be said then that most people distinguish "good" and "bad" impulses, or impulses which must be inhibited and impulses which should be followed at all costs.
