The young people should further be in full sympathy with each other’s views of life. The reason why so many marriages of to-day prove failures is that this rule is disregarded. Modern men are drunk with sensual pleasure and lay an exaggerated emphasis on physical qualities. They do not look for responsiveness and sympathy in their future partners but for vulgar eroticism. Animal sensuality in all its organic spontaneity control their choosing of a wife. Hence she is often taken from such walks of life where pleasure is the chief aim of existence. No wonder that such actually bought happiness soon languishes, and the man finds that the woman he has chosen as his life-partner has nothing in common with him except the mania for pleasure. The craze for luxuries of home and dress and the extravagance of the entire mode of living has taken such a hold upon modern women that most of them sell themselves into matrimony to the first man whom they consider able to provide them with luxuries, without regard to the manly qualities such as courage, intelligence, education, culture, generosity and chivalry, qualities which in former times made men attractive to women. The parties contracting marriage should be of suitable age. A difference in age from seven to fifteen years will bring the happiest results. In our climate a woman’s sexual life ceases about the age of forty-five, and man’s about sixty. Hence there is a difference of about fifteen years in favor of the man.[CM] In our climate the best age for women to become wives and mothers is from twenty-four to twenty-eight years.[CN] If the man is then about ten years older, the couple is physically well mated.
