Even when the emotion aroused is disgust it may still act as a sexual stimulant. Stcherbak has narrated the instructive case of a very intelligent and elegant married lady of rather delicate constitution, an artist of some talent, who never experienced any pleasure in sexual intercourse, but ever since sexual feelings first began to be manifested at all (at the age of 18) has only experienced them in relation to disgusting things. Anything that is repulsive, like vomit, etc., causes vague but pleasurable feelings which she gradually came to recognize as sexual. The sight of a crushed frog will cause very definite sexual sensations. She has had many admirers and she has observed that a declaration of love by a disagreeable or even repulsive man sexually excites her, though she has no desire for sexual intercourse with him.[147] After all that has gone before it is easy to see how the emotion of fear may act in an analogous manner to anger. Just as anger may reinforce the active forms of the sexual impulse to which it is allied, so fear may reinforce the passive forms of that impulse. The following observations, written by a lady, very well show how we may thus explain the sexual attractiveness of whipping: "The fascination of whipping, which has always greatly puzzled me, seems to be a sort of hankering after the stimulus of fear. In a wild state animals live in constant fear. In civilized life one but rarely feels it. A woman's pleasure in being afraid of a husband or lover may be an equivalent of a man's love of adventure; and the fear of children for their parents may be the dawning of the love of adventure. In a woman this desire of adventure receives a serious check when she begins to realize what she might be subjected to by a man if she gratified it. Excessive fear is demoralizing, but it seems to me that the idea of being whipped gives a sense of fear which is not excessive. It is almost the only kind of pain (physical) which is inflicted on children or women by persons whom they can love and trust, and with a moral object. Any other kind of bodily ill treatment suggests malignity and may rouse resentment, and, in extreme cases, an excess of fear which goes beyond the limits of pleasurable excitement. Given a hereditary feeling of this sort, I think it is helped by the want of actual experience, as the association with excitement is freed from the idea of pain as such." In his very valuable and suggestive study of fears, Stanley Hall, while recognizing the evil of excessive fear, has emphasized the emotional and even the intellectual benefits of fear, and the great part played by fear in the evolution of the race as "the rudimentary organ on the full development and subsequent reduction of which many of the best things in the soul are dependent." "Fears that paralyze some brains," he remarks, "are a good tonic for others. In some form and degree all need it always. Without the fear
