“It is necessary to create constraints, in order to invent freely. In poetry the constraint can be imposed by meter, foot, rhyme, by what has been called the "verse according to the ear."... In fiction, the surrounding world provides the constraint. This has nothing to do with realism... A completely unreal world can be constructed, in which asses fly and princesses are restored to life by a kiss; but that world, purely possible and unrealistic, must exist according to structures defined at the outset (we have to know whether it is a world where a princess can be restored to life only by the kiss of a prince, or also by that of a witch, and whether the princess's kiss transforms only frogs into princes or also, for example, armadillos).”

“This has nothing to do with realism (even if it explains also realism). A completely real world can be constructed, in which asses fly and princesses are restored to life by a kiss, but that world, purely possible and unrealistic, must exist according to structures defined at the outset (we have to know whether it is a world where a princess can be restored to life only by the kiss of a prince, or also by that of a witch, and whether the princess's kiss tranforms only frogs into princes or also, for example, armadillos).”

“There's nothing deeper than love. In fairy tales, the princesses kiss the frogs, and the frogs become princes. In real life,the princesses kiss princes, and the princes turn into frogs.”

“In the years when I discoverd the Abbé Vallet volume, there was a widespread conviction that one should write only out of a commitment to the present, in order to change the world. Now, after ten years or more, the man of letters (restored to his loftiest dignity) can happily write out of pure love of writing.”

“Then why do you want to know?""Because learning does not consist only of knowing what we must or we can do, but also of knowing what we could do and perhaps should not do.”

“In fairy tales, the princesses kiss the frogs, and the frogs become princes. In real life, the pricesses kiss princes, and the princes turn into frogs.”

“Show not what has been done, but what can be. How beautiful the world would be if there were a procedure for moving through labyrinths.”
