But it often happens unconsciously, in yawning for example, that one man suggests it to another who begins to yawn; or the sight of certain objects, the hearing of certain sounds, provokes suggestions. Thus the sight of an object belonging to a certain woman may cause an erection; the odor of some article of diet which has caused indigestion is sufficient to cause nausea, etc. We thus see that there is a series of transitions between external intentional suggestion and auto-suggestion, in the form of suggestion of objects and unconscious or involuntary suggestion of persons. The conception of true or intentional suggestion infers the determined will of one man influencing another by suggestion; there is no other criterion. It is quite another question whether the one who suggests wishes to benefit his subject, or wishes on the contrary to abuse him or make him ridiculous. =Sympathy. Love and Suggestion.=--It is of great importance for us to know that sympathy and confidence are the fundamental elements of success in suggestive action. Even when deceived by the one who hypnotizes him, the subject may yield to him while he is not aware of it. But there is here a point to be noted. A man may very well see clearly with his reason and his logic, he may understand that harm is done to him, he may even curse a thing or a person when he reflects, and in spite of this be instinctively and subconsciously attracted toward this thing or this person, like a moth to a candle, when certain sentiments of sympathy or attraction urge him to it. The two following examples will make this more clear: (1). An actor fell in love with a hysterical married woman. This woman was very polyandrous, and deceived not only her husband but the actor and many others. The actor tried with all the power of his reason to be delivered from the tyrannical charm of this siren; but the power of attraction of the woman was so strong that he could not succeed in resisting her. He came to me in despair and begged me to rid him of his passion by hypnotism. I realized the difficulty of the situation but did my best to help him. Although aided by his reason, all my suggestions were overcome by the violence of the passion that his hysterical seducer had inspired in him, and I obtained absolutely no result.
