Well, I think my paintings are fast enough already... - Piet Mondrian

It is clear to me that this [his recent works and ideas on art] is art for the future. Futurism, although it has advanced beyond naturalism, occupies itself too much with human sensations. Cubism – which in its content is still too much concerned with earlier aesthetic products, and thus less rooted in its own time than Futurism – Cubism has taken a giant step in the direction of abstraction, and is in this respect of its own time and of the future. Thus in its content it is not modern, but in its effect it is.

You should remember that my things are still intended to be paintings, that is to say, they are plastic representations, in and by themselves, not part of a building. Furthermore, they have been made in a small room. Also, that I use subdued colours for the time being, adapting myself to the present surroundings and to the outer world; this does not mean that I should not prefer a pure colouring. Otherwise you might think that I contradict myself in my work.

The rectangular plane of varying dimensions and colours visibly demonstrates that internationalism does not mean chaos ruled by monotony but an ordered and clearly divided unity. In Neo-Plasticism, there are, in fact, very definite boundaries. But these boundaries are not really closed; the straight lines in rectangular opposition to one another constantly intersect, so that their rhythm continues throughout the whole work.. .These frontiers will be clearly defined but not 'closed'; there will be no customs, no work permits. 'Foreigners' will not be viewed as aliens.
