    The education comes to us from nature, from men, or from things. The inner growth of our organs and faculties is the education of nature, the use we learn to make of this growth is the education of men, what we gain by our experience of our surroundings is the education of things.
    Thus we are each taught by three masters.  If their teaching conflicts,  the scholar is ill-educated and will never be at peace with himself; if their teaching agrees, he goes straight to his goal, he lives at peace with himself, he is well-educated.

    Viewed as an art,  the success of education is almost impossible,  since the essential conditions of success are beyond our control. Our efforts may bring us within sight of the goal, but fortune must favour us if we are to reach it.
