"I know that you are looking for the Blue Bird, that is to say, the great secret of things and of happiness, so that Man may make our servitude still harder. … I do not hear the Animals... Where are they?... All this concerns them as much as us... We, the Trees, must not assume the responsibility alone for the grave measures that have become necessary... On the day when Man hears that we have done what we are about to do, there will be terrible reprisals... It is right, therefore, that our agreement should be unanimous, so that our silence may be the same..."

“You know, my brothers, the nature of our business. The child you see before you, thanks to a talisman stolen from the powers of Earth, is able to take possession of the Blue Bird and thus to snatch from us the secret which we have kept since the origin of life... Now we know enough of Man to entertain no doubt as to the fate which he reserves for us once he is in possession of this secret. That is why it seems to me that any hesitation would be both foolish and criminal... It is a serious moment; the child must be done away with before it is too late...”

“It is not my purpose here to discuss the question of vegetarianism, or to meet the objections that may be urged against it; though it must be admitted that of these objections not one can withstand a loyal and scrupulous inquiry. I, for my part, can affirm that those whom I have known to submit themselves to this regimen have found its result to be improved or restored health, marked addition of strength, and the acquisition by the mind of a clearness, brightness, well-being, such as might follow the release from some secular, loathsome, detestable dungeon.”

“I knew that if I was captured by the Germans I would be shot at once, since I have always been counted as an enemy of Germany because of my play, Le Bourgmestre de Stillemonde, which dealt with the conditions in Belgium during the German Occupation of 1918.”

“Men's weaknesses are often necessary to the purposes of life.”

“The future is a world limited by ourselves; in it we discover only what concerns us and, sometimes, by chance, what interests those whom we love the most.”

“For in truth all our justice, morality, all our thoughts and feelings, derive from three or four primordial necessities, whereof the principal one is food. The least modification of one of these necessities would entail a marked change in our moral existence. Were the belief one day to become general that man could dispense with animal food, there would ensue not only a great economic revolution--for a bullock, to produce one pound of meat, consumes more than a hundred of provender--but a moral improvement as well, not less important and certainly more sincere and more lasting than might follow a second appearance on the earth of the Envoy of the Father, come to remedy the errors and omissions of his former pilgrimage. For we find that the man who abandons the regimen of meat abandons alcohol also; and to do this is to renounce most of the coarser and more degraded pleasures of life. And it is in the passionate craving for these pleasures, in their glamour, and the prejudice they create, that the most formidable obstacle is found to the harmonious development of the race.”
