“In anything at all, perfection is finally attained not when there is no longer anything to add, but when there is no longer anything to take away, when a body has been stripped down to its nakedness.”
Ch III : The Tool
Variant translation of: <span id="perfection"></span>Il semble que la perfection soit atteinte non quand il n'y a plus rien à ajouter, mais quand il n'y a plus rien à retrancher.
Ch. III: L'Avion <!-- p. 60 -->
It seems that perfection is attained not when there is nothing more to add, but when there is nothing more to remove.
Terre des Hommes (1939)
Context: Have you looked at a modern airplane? Have you followed from year to year the evolution of its lines? Have you ever thought, not only about the airplane but about whatever man builds, that all of man's industrial efforts, all his computations and calculations, all the nights spent over working draughts and blueprints, invariably culminate in the production of a thing whose sole and guiding principle is the ultimate principle of simplicity?
It is as if there were a natural law which ordained that to achieve this end, to refine the curve of a piece of furniture, or a ship's keel, or the fuselage of an airplane, until gradually it partakes of the elementary purity of the curve of a human breast or shoulder, there must be the experimentation of several generations of craftsmen. In anything at all, perfection is finally attained not when there is no longer anything to add, but when there is no longer anything to take away, when a body has been stripped down to its nakedness.

Context: There are only two possibilities in Germany; do not imagine that the people will forever go with the middle party, the party of compromises; one day it will turn to those who have most consistently foretold the coming ruin and have sought to dissociate themselves from it. And that party is either the Left: and then God help us! for it will lead us to complete destruction - to Bolshevism, or else it is a party of the Right which at the last, when the people is in utter despair, when it has lost all its spirit and has no longer any faith in anything, is determined for its part ruthlessly to seize the reins of power - that is the beginning of resistance of which I spoke a few minutes ago. Here, too, there can be no compromise - there are only two possibilities: either victory of the Aryan, or annihilation of the Aryan and the victory of the Jew.

“Artists who seek perfection in everything are those who cannot attain it in anything.”
Les artistes qui cherchent la perfection en tout sont ceux qui ne peuvent l'atteindre en aucune partie.
