Dear Does [= Theo van Doesburg ], thank you for your letter.. .I was glad to know that in principle you are in favour of the diamond hanging [Mondria… - Piet Mondrian

..the elements of form have a particular aspect; every fragment, every plane, every line has its proper character.

[Paris, as modern city] is beautiful in its perfection, but perfection means death and decay. Thus interfering with the process of dying is a crime against perfection: it stands in the way of a higher perfection.

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.
