When I first saw the work of the Impressionists, Van Gogh, Van Dongen and the Fauves, I admired it. But I had to seek the true way alone. - Piet Mondrian

And now about architects in general – I have to say it, Does [= Theo van Doesburg ], when 'De Stijl' was founded I left it up to you, but I never did agree with you when you ranked the architects alongside us, alongside our 'N.B.' ( / Neo-Plasticism) I knew then that it would lead to conflict.. .I cannot write about architecture, because I'm not an architect. I mean, I cannot write about the way I write about painting. Later on, though, I will put forward a few ideas.

Culture produces relative consciousness of the changeable expression of reality. When this consciousness is attained, a revolt takes place: the beginning of the deliverance from that expression of reality. Destruction of its limitation follows. The culture of the intuitive faculties has conquered. A clearer perception of constant reality is possible. A new realism appears.

I remained there [in The Netherlands, 1914-18] for the duration of the war, continuing my work of abstraction in a series of church. facades, trees, houses, etc. But I felt that I still worked as an Impressionist and was continuing to express particular feelings, not pure reality. Although I was thoroughly conscious that we can never be absolutely 'objective', I felt that one can become less and less subjective, until the subjective no longer predominates in one's work. More and more I excluded from my painting all curved lines, until finally my compositions consisted only of vertical and horizontal lines which formed crosses, each separate and detached from the other. Observing sea, sky and stars, I sought to indicate their plastic function through a multiplicity crossing verticals and horizontals.
