You can so wonderfully be yourself here [in Paris]. - Piet Mondrian

With that work [Mondrian is referring to his figurative painting 'Devotion' he painted in 1908, of a devotedly looking girl] I only envisaged a girl conceived devotedly.. ..and by giving the hair that sort of red, to tone down the material side of things, to suppress any thoughts about 'hair', 'costume', etc, and to stress the spiritual. I believe that color and line can do much towards this end; moreover, I should not wish to do without line.. .It is precisely the overall line of a thing which I find fundamentally important, and also, the colour.

They [Mondrian's friends in Paris, Tonia and Wim Stieltjes] are receptive to the new, although they do not know what it is. Thus I do occasionally feel that my effort has not been in vain. They find the idea of the N.B. [= Dutch: / Neo Plasticism] sound and quite magnificent, but think that it will be quite a long time before people are ready for it.

If, then, we focus our attention on the balanced relation, we shall be able to see unity in natural things. However, there it appears under a veil. But even though we never find unity expressed exactly, we can unify every representation, in other words, the exact representation of unity can be expressed; it must be expressed, for it is not visible in concrete reality.
