- Abnormal suggestibility varies as direct suggestion and inversely as indirect suggestion.
A comparison of the conditions of normal and abnormal suggestibility is valuable, since it reveals the nature of suggestibility, and discloses its fundamental law. An examination of the two sets of conditions shows that in abnormal suggestibility two conditions, distraction of attention and immediate execution are absent, otherwise the conditions are the same. This sameness of conditions clearly indicates the fact that both normal and abnormal suggestibility flow from some one common source, that they are of like nature, and due to similar causes. Now a previous study led us to the conclusion that the nature of abnormal suggestibility is a disaggregation of consciousness, a slit produced in the mind, a crack that may become wider and deeper, ending in a total disjunction of the waking, guiding, controlling consciousness from the reflex consciousness. Normal suggestibility is of like nature, it is a cleft in the mind; only here the cleft is not so deep, not so lasting as it is in hypnosis, or in the state of abnormal suggestibility. The split is here but momentary, disappearing almost at the very moment of its appearance.
This fleeting, evanescent character of the split explains why suggestion in the normal state, why normal suggestibility requires immediate execution as one of its indispensable conditions. We must take the opportunity of the momentary ebb of the controlling consciousness and hastily plant our suggestion in the soil of reflex consciousness. We must watch for this favorable moment, not let it slip by, otherwise the suggestion is a failure. Furthermore, we must be careful to keep in abeyance, for the moment, the ever-active waves of the controlling consciousness. We must find for them work in some other direction; we must divert, we must distract them. That is why normal suggestibility requires the additional conditions of distraction and of immediate execution. For in the waking state the waking, controlling consciousness is always on its guard, and, when enticed away, leaves its ground only for a moment. In normal suggestibility the psychic split is but faint; the lesion, effected in the body consciousness, is superficial, transitory, fleeting. In abnormal suggestibility, on the contrary, the slit is deep and lasting,—it is a severe gash. In both cases, however, we have a removal, a dissociation of the waking from the subwaking, reflex consciousness, suggestion becoming effected only through the latter. For suggestibility is the attribute of the subwaking, reflex consciousness.
