In the preceding lecture to the parents and teachers of young men I emphasized the importance of developing the young man's ideals of love and marriage primarily because such ideals have so often helped men morally in character-formation and character-protection. I feel sure that this is not the chief reason why the ideals of young women should be developed along parallel lines. On the contrary, it seems to me that those representative women are right who think that the first reason why ideals of young women should be influenced is that there is need of a radical change in the attitude of a very common type of young women who are flippant and disrespectful concerning love and marriage, and whose influence on the morals of men is decidedly bad because they often give unguided young men their first and strongest impressions concerning women. A second reason, which is equally applicable to both sexes, is that advance understanding of the relations of love and marriage is likely to lead to happy and satisfactory adjustment in marriage. [Sidenote: Men naturally lead in love.] Perhaps the flippant and disrespectful attitude concerning affairs of the heart develops in many young women because they do not consciously feel in advance of experience the demand for affection which comes so naturally and spontaneously to many, possibly to all, normal young men whose views of life have not been artificially twisted. I fully realize the treacherous nature of the ground on which walks one who tries to compare the two sexes concerning their relative attitudes towards love, but certain it is that the novelist's descriptions of men as the leaders and aggressors in love is not fiction but the common fact of real life. Man's tendency towards leadership in love is not scientifically explained by any superficial assumption that established social conventions have repressed an original spontaneity of women. On the contrary, there are the best of physiological and psychological reasons for believing that the social conventions have arisen as an expression of masculine aggressiveness and natural tendency towards leadership in affairs of the heart. The accepted fact is that many young women have no understanding of or demand for affection until experience has taught them its place in life. In the records of real life, as well as in fiction, many a young woman's possibilities of happiness have been lost because she did not understand herself when love came into her experience.
