It is a fact that many young people who refuse to be interested in religious literature may be influenced for sexual purity by the emotional appeal of some general literature. This is especially true of romantic poetry. I believe that the high "idealism" of love inspired by Tennyson's "The Princess" and "Idylls of the King," by Longfellow's "Evangeline" and "The Hanging of the Crane," by some of Shakespeare's plays, and by other great poetry with similar themes has had and will continue to have greater influence on the attitude and ethics of many young people than all the formal sex-teaching that can be organized. Hence, I believe that teachers of literature should be led to take interest in the larger sex-education to the end that by selection and interpretation of great masterpieces they may contribute in a valuable way to the solution of some of the problems that have their center in the deeper nature of sex. [Sidenote: Importance of interpretation.] Interpretation of literature by teachers is very important for the purposes of sex-education of young people. As an example, take Tennyson's "Idylls of the King," whose movement centers in the life problems that turn around love. The average reader is likely to miss the great lessons if the poem is not critically interpreted either by living teachers or by such critical essays as those by Henry van Dyke in his "Poetry of Tennyson" and Newell Dwight Hillis in his "Great Books as Life-Teachers." Without interpretation "The Idylls" may teach false as well as true lessons of life. Some of the Knights of the Round Table (Galahad and Percivale) were worthy followers of the good and pure King Arthur, and some of them (like Lancelot and Tristram and Merlin) proved unable to live up to the vow of chastity to which Arthur swore all his knights. And on the part of the ladies of Arthur's court, there was purity and devotion and true womanhood in Elaine and Enid, while Guinevere and Ettarre and Vivien were unchaste and faithless. In fact, all phases of the relations of men and women in the struggles and perplexities of life are pictured; and therefore it is important that a well-trained teacher should be the guide and interpreter if the "Idylls of the King" are to be read with the idea of understanding their true bearings on life, which includes their contribution to the larger sex-education.
