It should be said that such an art would be neither more false nor more true than classical art. - Jean Metzinger

But we cannot enjoy in isolation; we wish to dazzle others with that which we daily snatch from the world of sense, and in return we wish others to show us their trophies. From a reciprocity of concessions arise those mixed images, which we hasten to confront with artistic creations in order to compute what they contain of the objective; that is of the purely conventional.

The excuse that the painters were documenting reality was becoming ridiculous. Photographers and film makers went far beyond them. Already it could be said that a good portrait led one to think about the painter not the model.

In fact it is a stupidity, Maurice Princet told me in the presence of Juan Gris, to claim to be able to bring together in a single system of relations, colour, which is a sensation that only needs to be received, and form which is an organisation that has to be understood (14); and, introducing us to the non-Euclidean geometries, he urged us to create a geometry for painters.
