typical of the sentiment of shame. Still, such cases are comparatively rare; and in contrast with them we may often note that older children, even girls of eight or a little more, will in play raise their petticoats so high that it is necessary to turn away if we wish to avoid seeing the genital organs, and often a word of reproof is needed from the mother or nurse to indicate to the child that it is doing something improper. The fact that in little children the sense of shame is so little developed, but that subsequently this sentiment becomes clearly manifest, has been used as an argument against the theory that it is inborn; but this argument cannot be accepted without reserve, for an inborn quality may not manifest itself until a certain definite age is reached--as we see clearly in the case of the sexual impulse--and this apart from the consideration that the development of an inborn quality may be inhibited by influences acting during the individual life. Whatever view we take of this problem, there can be no doubt as to the possibility of exerting a marked influence upon both qualities, the sentiment of disgust and the sentiment of shame, by means of influences operating during the lifetime of the individual. Thus, by education and habituation, it is possible to learn to repress disgust towards certain animals or certain excreta, as is done by the physician, and by nurses, male and female. The sentiment of disgust also depends largely upon general customs. The civilised European makes a mock of the fact that other races, certain oriental races, for instance, eat foods which to us are disgusting. A European invited as a guest at certain foreign banquets, is thoroughly disgusted when he sees food put into the mouth with the fingers instead of with knife and fork. And yet there is no great difference in respect of our own practice, when we put a piece of chocolate, a grape, or the like, into our own mouths. If, in Europe, we saw someone eating a pigeon in the same way as that in which we are accustomed to eat a crayfish, many persons would experience disgust. And yet, objectively considered, there is no reason to be less disgusted at the eating of crayfishes than when some other kind of animal is eaten in the same manner. Such modification of the sentiment of disgust by habit and custom applies also to sexual matters. A girl who experiences disgust at the sight of semen or the act of its ejaculation, may, through habituation, cease to feel such disgust.
