"Remember that to guide a grown man you must reverse all that you did to guide the child. Do not hesitate to speak to him of those dangerous mysteries which you have so carefully concealed from him hitherto. Since he must become aware of them, let him not learn them from another, nor from himself, but from you alone; since he must henceforth fight against them, let him know his enemy, that he may not be taken unawares. What makes me most confident in my method is this: when I follow it out as closely as possible, I find no situation in the life of my scholar which does not leave me some pleasing memory of him. Even when he is carried away by his ardent temperament or when he revolts against the hand that guides him, when he struggles and is on the point of escaping from me, I still find his first simplicity in his agitation and his anger; his heart as pure as his body, he has no more knowledge of pretence than of vice; reproach and scorn have not made a coward of him; base fears have never taught him the art of concealment. He has all the indiscretion of innocence; he is absolutely out-spoken; he does not even know the use of deceit. Every impulse of his heart is betrayed either by word or look, and I often know what he is feeling before he is aware of it himself."
