Here we are at the antipode of automatism [invention from Surrealism] and mechanism, and no less distant from the cunning way of reason. In the action of the machine, in which everything is repeated and predetermined, accident is an abrupt negation.... [the] excess of ink flowing capriciously in thin black rivulets.... this line deflected by a sudden jar, this drop of water diluting a contour – all these are the sudden invasion of the unexpected in a world where it has a right to its proper place.
