The significant fact is that these attitudes function by limiting the range of stimuli to which the person is sensitive. The attitude of shame concerning their sexual functions, which has been impressed upon women as a result of ages of thinking in harmony with taboo standards, thus is able to prevent the normal biological response to a situation which should call out the emotions of love. In women who have an unstable nervous system this shameful feeling often results in a definite physiological shrinking from the physical manifestations of sexuality and renders the individual insensitive to all erotic stimulation. This attitude of shame in connection with the love life came into existence as a socially conditioned emotional reaction set up under the influence of the traditional ideal of the "model woman" who was pictured as a being of unearthly purity and immaculacy. It has been passed on from generation to generation through an unconscious conditioning of the daughter's attitude by suggestion and imitation to resemble that of the mother. Thus it happens that although an increasing amount of liberty, both social and economic, and a more rational and scientific understanding of the womanly nature, have quite revoked this ideal in theory, in actual practice it still continues to exert its inhibitory and restrictive influence. Because the standardized family relationship involves so much more radical a readjustment in the life of woman than of man, it has almost always been the feminine partner who has taken refuge in neurotic symptoms in order to escape the difficulties of the situation. After the marriage ceremony, the man's life goes on much as before, so far as his social activities are concerned, but woman takes up the new duties connected with the care of the home and her child-bearing functions. Moreover, the sexual life of woman is in many ways more complex than that of man. She has been subjected to more repressions and inhibitions, and as a result there has been more modification of her emotional reactions in the field of love. This greater complexity of her love life makes adaptation to marriage more problematical in the case of woman. Although the neurotic tendencies of modern women have been an important factor for the production of disharmony in the family life, there are certain variations of the individual sex life which are more universally significant. The conditioned emotional reactions which environmental influences have built up around the sexual impulse of each member of society invariably determine the choice of the mate and give rise to extremely complicated problems by the very nature of the selective process. It is largely a matter of chance whether the mate chosen in accordance with the ideals of romantic love and because of some fascinating trait which acts as an erotic fetish or in conformity with a parental fixation will prove a congenial companion through life.
