I comment as follows: (1) Dr. Maxwell refers only to the "extreme advocates." They did exist in abundance a few years ago, but are already rare in the group of well-known educators. (2) Most teachers are not prepared and never can be prepared to teach the human aspect of sex problems, especially the hygienic in the strict sense. (3) Conservative sex-instruction such as was advocated by the advisers of the American Federation for Sex-hygiene (see "Report" by Morrow and others, 1913) aims to guard against "premature interest in the sexual passion." (4) While I sympathize with Dr. Maxwell's view that teaching the elementary hygiene of sex is the parent's duty, I am forced to recognize the futility of advocating that all or even a respectable minority of parents should undertake their duty (see Sec. 4). The truth is that most of them will not, and cannot if they will, try to do so. (5) Dr. Maxwell's idea that sex-hygiene should be taught only when an astute principal or parent "detects wrong-doing" is, to say the least, an educational theory that will astonish one who knows even the elementary facts regarding the secrecy of the sexual life of young people in general. Will he next be logically consistent and advocate that all moral education should be given only after children show signs of wrong-doing? (6) Sex-hygiene, as Dr. Maxwell understands it to be concerned directly and solely with human sexual problems, will never be taught in American schools controlled by people of good sense; but sex-instruction from the larger viewpoint is taught in some of the best of Dr. Maxwell's high schools. (7) All advocates of sex-instruction who have a national reputation for educational sanity agree that legislation is most undesirable. (8) It is obvious that like so many others who have become confused regarding the sex-education movement, Dr. Maxwell has been impressed chiefly by the pioneer work that emphasized only hygienic teaching regarding sex. Sec. 48. _Lubricity in Education_ Ex-President Taft has expressed his views against the sex-education movement. The newspapers quote as follows from an address delivered in Philadelphia in 1914: "There is another danger in our educational influences and environment. I refer to the spread of lubricity in literature, on the stage and indirectly in education, under the plea that vice may be avoided by teaching the awful consequences. By dwelling on its details and explaining its penalties, sexual subjects are obtruded into discussion between the sexes, lectures are delivered on them, textbooks are written, and former restraints of modesty are abandoned. [Sidenote: Mr. Taft's alarm.]
