Piet Mondrian Quote
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.
In 'The New Art – The New Life', Piet Mondrian, op. cit. Introd. Note 1., 1931
