From being in love to hypnosis is evidently only a short step. The respects in which the two agree are obvious. There is the same humble subjection, the same compliance, the same absence of criticism, towards the hypnotist just as towards the loved object. There is the same absorption of one's own initiative; no one can doubt that the hypnotist has stepped into the place of the ego ideal. It is only that everything is even clearer and more intense in hypnosis, so that it would be more to the point to explain being in love by means of hypnosis than the other way round. The hypnotist is the sole object, and no attention is paid to any but him. The fact that the ego experiences in a dream-like way whatever he may request or assert reminds us that we omitted to mention among the functions of the ego ideal the business of testing the reality of things.[49] No wonder that the ego takes a perception for real if its reality is vouched for by the mental faculty which ordinarily discharges the duty of testing the reality of things. The complete absence of tendencies which are uninhibited in their sexual aims contributes further towards the extreme purity of the phenomena. The hypnotic relation is the devotion of someone in love to an unlimited degree but with sexual satisfaction excluded; whereas in the case of being in love this kind of satisfaction is only temporarily kept back, and remains in the background as a possible aim at some later time. But on the other hand we may also say that the hypnotic relation is (if the expression is permissible) a group formation with two members. Hypnosis is not a good object for comparison with a group formation, because it is truer to say that it is identical with it. Out of the complicated fabric of the group it isolates one element for us--the behaviour of the individual to the leader. Hypnosis is distinguished from a group formation by this limitation of number, just as it is distinguished from being in love by the absence of directly sexual tendencies. In this respect it occupies a middle position between the two. It is interesting to see that it is precisely those sexual tendencies that are inhibited in their aims which achieve such lasting ties between men. But this can easily be understood from the fact that they are not capable of complete satisfaction, while sexual tendencies which are uninhibited in their aims suffer an extraordinary reduction through the discharge of energy every time the sexual aim is attained. It is the fate of sensual love to become extinguished when it is satisfied; for it to be able to last, it must from the first be mixed with purely tender components--with such, that is, as are inhibited in their aims--or it must itself undergo a transformation of this kind.
