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

It is the same with art. Art will become the product of another duality in man: the product of a cultivated externality and of an inwardness deepened and more conscious. As a pure representation of the human mind, art will express itself in an aesthetically purified, that is to say, abstract form.

My new installment [Mondrian moved to a new studio in Paris, where he applied the principles of Neo-Plasticism into the interior of his studio ] is about decoration, occasioned by my studio here, where I've set up a sort of display. I couldn't work directly on the walls, so I had to make do with pieces of painted cardboard. But in any case, I am now convinced that in this way it is possible to realize Neo-Plasticism in the interior. Of course I had to paint the furniture as well. It was worth the effort, as it has a favourable influence on my work.

I believe that in our period it is definitely necessary that, as far as possible, the paint is applied in pure colours, set next to each other in a pointillist or diffuse manner. This is stated strongly, and yet it relates to the idea which is the basis of meaningful expression in form, as I see it. It seems to me that the clarity of ideas should be accompanied by a clarity of technique.
