With the hope of locating the weaknesses of sex-education, I have for years examined carefully every criticism published, and it seems to me thoroughly scientific to conclude that all the important criticisms have not harmed the essentials of the sex-education movement; but, on the contrary, have been helpful in forcing reconstruction. In fact, the present-day conception of the larger sex-education must be credited to the severe critics more than to the friends of the original narrow movement for reducing venereal disease by hygienic instruction. XI THE PAST AND THE FUTURE OF THE SEX-EDUCATION MOVEMENT Sec. 50. _The American Movement_ [Sidenote: Dr. Morrow leader in America.] In America the movement for sex-education began with the organization of the American Society of Sanitary and Moral Prophylaxis on February 9, 1905, under the leadership of Dr. Prince A. Morrow. It is true that before this time there were various local and sporadic attempts at instruction concerning sexual processes, but such teaching was chiefly personal and there was no concerted movement looking towards making sex-instruction an integral part of general education. In 1892, thirteen years before the organization of the Society of Sanitary and Moral Prophylaxis, a group of members of the National Education Association considered briefly the importance of instructing young people. However, this meeting was of ephemeral significance and had no genetic relation to the present-day movement. Other early interest in sex-instruction is indicated in Professor Earl Barnes's bibliography which was published in his "Studies in Education," Vol. I, p. 301, 1897. The educational activities, especially the publications of the American Society of Sanitary and Moral Prophylaxis, soon attracted the serious attention of numerous physicians, ministers, and educators in various parts of the United States; and about twenty other societies for study and improvement of the sex problems were organized within a few years after the original society.
