“ In the first place, I believe that an advance in our knowledge of the sexual life of the child will indirectly enrich our knowledge also of the sexual life of the adult. In order to understand the sexual life, the gradual development of that life must be recognised, and for this purpose it is essential that we should study the sexual life of the child. Moreover, the modern movement in favour of the sexual enlightenment of young persons renders indispensable the possession of precise knowledge of the sexuality of the child ”

“ The number of books and essays dealing with sexual topics published during recent years is by no means small; but although some of the works in question have added considerably to our knowledge, the advance of sexual science as a whole has not been proportionate to the extent of these contributions. ”
