It may be said that the special attractiveness which the nakedness of great literature sometimes possesses for young minds is unwholesome. But it must be remembered that the peculiar interest of this element is merely due to the fact that elsewhere there is an inveterate and abnormal concealment. It must also be said that the statements of the great writers about natural things are never degrading, nor even erotically exciting to the young, and what Emilia Pardo Bazan tells of herself and her delight when a child in the historical books of the Old Testament, that the crude passages in them failed to send the faintest cloud of trouble across her young imagination, is equally true of most children. It is necessary, indeed, that these naked and serious things should be left standing, even if only to counterbalance the lewdly comic efforts to besmirch love and sex, which are visible to all in every low-class bookseller's shop window. This point of view was vigorously championed by the speakers on sexual education at the Third Congress of the German Gesellschaft zur Bekämpfung der Geschlechtskrankheiten in 1907. Thus Enderlin, speaking as a headmaster, protested against the custom of bowdlerizing poems and folk-songs for the use of children, and thus robbing them of the finest introduction to purified sexual impulses and the highest sphere of emotion, while at the same time they are recklessly exposed to the "psychic infection" of the vulgar comic papers everywhere exposed for sale. "So long as children are too young to respond to erotic poetry it cannot hurt them; when they are old enough to respond it can only benefit them by opening to them the highest and purest channels of human emotion" (_Sexualpädagogik_, p. 60). Professor Schäfenacker (id., p. 98) expresses himself in the same sense, and remarks that "the method of removing from school-books all those passages which, in the opinion of short-sighted and narrow-hearted schoolmasters, are unsuited for youth, must be decisively condemned." Every healthy boy and girl who has reached the age of puberty may be safely allowed to ramble in any good library, however varied its contents. So far from needing guidance they will usually show a much more refined taste than their elders. At this age, when the emotions are still virginal and sensitive, the things that are realistic, ugly, or morbid, jar on the young spirit and are cast aside, though in adult life, with the coarsening of mental texture which comes of years and experience, this repugnance, doubtless by an equally sound and natural instinct, may become much less acute.
