"We are born, so to speak, twice over; born into existence, and born into life; born a human being, and born a man. Those who regard woman as an imperfect man are no doubt mistaken, but they have external resemblance on their side. Up to the age of puberty children of both sexes have little to distinguish them to the eye, the same face and form, the same complexion and voice, everything is the same; girls are children and boys are children; one name is enough for creatures so closely resembling one another. Males whose development is arrested preserve this resemblance all their lives; they are always big children; and women who never lose this resemblance seem in many respects never to be more than children. But, speaking generally, man is not meant to remain a child. He leaves childhood behind him at the time ordained by nature; and this critical moment, short enough in itself, has far-reaching consequences. As the roaring of the waves precedes the tempest, so the murmur of rising passions announces this tumultuous change; a suppressed excitement warns us of the approaching danger. A change of temper, frequent outbreaks of anger, a perpetual stirring of the mind, make the child almost ungovernable. He becomes deaf to the voice he used to obey; he is a lion in a fever; he distrusts his keeper and refuses to be controlled. With the moral symptoms of a changing temper there are perceptible changes in appearance. His countenance develops and takes the stamp of his character; the soft and sparse down upon his cheeks becomes darker and stiffer. His voice grows hoarse or rather he loses it altogether. He is neither a child nor a man and cannot speak like either of them. His eyes, those organs of the soul which till now were dumb, find speech and meaning; a kindling fire illumines them, there is still a sacred innocence in their ever brightening glance, but they have lost their first meaningless expression; he is already aware that they can say too much; he is beginning to learn to lower his eyes and blush, he is becoming sensitive, though he does not know what it is that he feels; he is uneasy without knowing why. All this may happen gradually and give you time enough; but if his keenness becomes impatience, his eagerness madness, if he is angry and sorry all in a moment, if he weeps without cause, if in the presence of objects which are beginning to be a source of danger his pulse quickens and his eyes sparkle, if he trembles when a woman's hand touches his, if he is troubled or timid in her presence, O Ulysses, wise Ulysses! have a care! The passages you closed with so much pains are open; the winds are unloosed; keep your hand upon the helm or all is lost. This is the second birth I spoke of; then it is that man really enters upon life; henceforth no human passion is a stranger to him. Our efforts so far have been child's play, now they are of the greatest importance. This period when education is usually finished is just the time to begin."
