Scientific discovery, especially in biology, during the past two decades has made necessary an entire restatement of the sociological problem of sex. Ward's so-called "gynæcocentric" theory, as sketched in Chapter 14 of his Pure Sociology, has been almost a bible on the sex problem to sociologists, in spite of the fact that modern laboratory experimentation has disproved it in almost every detail. While a comparatively small number of people read this theory from the original source, it is still being scattered far and wide in the form of quotations, paraphrases, and interpretations by more popular writers. It is therefore necessary to gather together the biological data which are available from technical experimentation and medical research, in order that its social implications may be utilized to show the obsoleteness of this older and unscientific statement of the sex problem in society.
