The Cubists, to be objective, restrict themselves to considering things by turning around them, to produce their geometric writing. So they remain at a stage of intelligence which sees everything and feels nothing, which brings everything to a standstill in order to describe everything. We Futurists are trying, on the contrary, with the power of intuition, to place ourselves at the very center of things, in such a way that our ego forms with their own uniqueness a single complex. We thus give plastic planes a plastic expansion in space, obtaining this feeling of something in perpetual motion which is peculiar to everything living.
