sees the great peasant girls, as ardent as mares in heat, abandoning themselves to the arms of robust youths. He cannot fail to remark these frank manifestations of sexuality, though the subtle and perverse refinements of the town would escape his notice. I know that in the countries of exaggerated prudery there is much hidden corruption, more, one is sometimes inclined to think, than in less hypocritical countries. But I believe that that is a false impression, and am persuaded that precisely because of all these little concealments which excite the malicious amusement of foreigners, there are really many more young people in England who remain chaste than in the countries which treat sexual relations more frankly. At all events, if I have known Englishmen who were very debauched and very refined in vice, I have also known young men of the same nation, over twenty, who were as innocent as children, but never a young Frenchman, Italian, or Spaniard of whom this could be said." There is undoubtedly truth in this statement, though it must be remembered that, excellent as chastity is, if it is based on mere ignorance, its possessor is exposed to terrible dangers. The question of sexual hygiene, more especially in its special aspect of sexual enlightenment, is not, however, dependent on the fact that in some children the psychic and nervous manifestation of sex appears at an earlier age than in others. It rests upon the larger general fact that in all children the activity of intelligence begins to work at a very early age, and that this activity tends to manifest itself in an inquisitive desire to know many elementary facts of life which are really dependent on sex. The primary and most universal of these desires is the desire to know where children come from. No question could be more natural; the question of origins is necessarily a fundamental one in childish philosophies as, in more ultimate shapes, it is in adult philosophies. Most children, either guided by the statements, usually the misstatements, of their elders, or by their own intelligence working amid such indications as are open to them, are in possession of a theory of the origin of babies.
