“Awaken people's curiosity. It is enough to open minds, do not overload them. Put there just a spark.”

“The whole art of teaching is only the art of awakening the natural curiosity of the mind for the purpose of satisfying it afterwards.”

“Alas!' replied Maître Mouche, 'she must be trained to take her part in the struggle of life. One does not come into this world simply to amuse oneself, and to do just what one pleases.''One comes into this world,' I responded, rather warmly, 'to enjoy what is beautiful and what is good, and to do as one pleases, when the things one wants to do are noble, intelligent, and generous.

“I have always preferred the folly of the passions to the wisdom of indifference. But just because my own passions are not of that sort which burst out with violence to devastate and kill, the common mind is not aware of their existence. Nevertheless, I am greatly moved by them at times, and it has more than once been my fate to lose my sleep for the sake of a few pages written by some forgotten monk or printed by some humble apprentice of Peter Schöffer.

Was this the tumultuous existence he must expect under my roof? Had there not been a tacit understanding between us that we should live a peaceful life? I had broken the covenant.”
