However, on the other hand, statistics as quoted above tell us that the death rate of infants is abnormally high, that preventable diseases are excessively prevalent, that divorces are too frequent, and that the "unpreparedness of women" is responsible for sickness, disability, degeneracy and resulting misery or maladjustment to society, and that if only the knowledge available for preventing disease could be disseminated and utilized, longevity would be much increased.
These facts show that while the mother in the home by the preparation of food and resulting responsibilities is doing much for race betterment, there is imperative need for greater ability in some way to enable woman to make use of the results of scientific research, in order that there may be in the human race "an increase of vitality, of sound and high mentality, and of sociality."

It ought to assert some control over the training of people who are to be in charge of the consumption of all wealth and of child culture in the home.

Each one of these divisions includes many departments of learning. To these subjects should be added a thorough knowledge of sex hygiene. With a knowledge of all these subjects should go an attitude of mind which is able to develop powers equal to one's tasks.
