A little later, when he has ceased to be a child and puberty is approaching, another question is apt to arise in the boy’s mind: What is a woman like? There is also, less often and more carefully concealed, the corresponding curiosity in the girl’s mind. Earlier this question had seemed of no interest; it had never even occurred to ask it; there was little realisation—sometimes none at all—of any sexual difference. Now it sometimes becomes a question of singular urgency, in the solution of which it is necessary for the boy to concentrate all the scientific apparatus at his command. For there may be no ways of solving it directly, least of all for a well-behaved, self-respecting boy or a shy, modest girl. The youthful intellect is thus held in full tension, and its developing energy directed into all sorts of new channels in order to form an imaginative picture of the unknown reality, fascinating because incompletely known. All the chief recognised mental processes of dogma, hypothesis, and fiction, developed in the history of the race, are to this end instinctively created afresh in the youthful individual mind, endlessly formed and re-formed and tested in order to fill in the picture. The young investigator becomes a diligent student of literature and laboriously examines the relevant passages he finds in the Bible or other ancient primitive naked books. He examines statues and pictures. Perhaps he finds some old elementary manual of anatomy, but here the long list of structures with Latin names proves far more baffling than helpful to the youthful investigator who can in no possible way fit them all into the smooth surface shown by the statues. Yet the creative and critical habit of thought, the scientific mind generated by this search, is destined to be of immense value, and long outlives the time when the eagerly sought triangular spot, having fulfilled its intellectual function, has become a familiar region, viewed with indifference, or at most a homely tenderness. That was but a brief and passing episode, however permanently beneficial its results might prove. With the achievement of puberty, with the coming of adolescence, a larger and higher passion fills the youth’s soul. He forgets the woman’s body, his idealism seems to raise him above the physical: it is the woman’s personality—most likely some particular woman’s personality—that he desires to know and to grasp.
