“I awaited Signor Polizzi's reply with ill-contained impatience. I could not even remain quiet; I would make sudden nervous gestures - open books and violent close them again. One day I happened to upset a book with my elbow - a volume of Moréri. Hamilcar, who was washing himself, suddenly stopped, and looked angrily at me, with his paw over his ear. 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.”

“Never lend books, for no one ever returns them; the only books I have in my library are books that other folks have lent me.”

“You see, Dimitri and I, we are both suffering from ennui! We have still the match-boxes. But at last one gets tired even of match-boxes. Besides, our collection will soon be complete. And then what are we going to do?"'Oh, Madame!' I exclaimed, touched by the moral unhappiness of this pretty person, 'if you only had a son, then you would know what to do. You would then learn the purpose of your life, and your thoughts would become at once more serious and yet more cheerful.''But I have a son,' she replied. 'He is a big boy; he is eleven years old, and he suffers from ennui like the rest of us. Yes, my George has ennui, too; he is tired of everything. It is very wretched.”

“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.

And if these fierce enthusiasms are slowly being quenched in me, it is only because I am being slowly quenched myself. Our passions are ourselves. My old books are Me. I am just as old and thumb-worn as they are.”

“This book bore the label R>3214 VIII/2. And this painful truth was suddenly borne in upon the mind of Monsieur Sariette: to wit, that the most scientific system of numbering will not help to find a book if the book is no longer in its place.”

“All changes, even the most longed for, have their melancholy; for what we leave behind us is a part of ourselves; we must die to one life before we can enter another.”

“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. An education which does not cultivate the will, is an education that depraves the mind. It is a teacher's duty to teach the pupil how to will.”
