From the Preface: 'This little book is born of the idea that mankind are suffering for want of the knowledge it is designed to give. A medical experience, extending through several years, has convinced me that people of all ages and both sexes are suffering from abuses of the sexual function. In a majority of instances, these abuses were begun and continued in ignorance of the results which were to follow. Children inherit strong sexual desires of which they do not know the meaning ; and, receiving no instruction with regard to these desires, they either fall spontaneously into evil practices, or learn from impure associates habits which eventually prove their ruin.'
