Culture produces relative consciousness of the changeable expression of reality. When this consciousness is attained, a revolt takes place: the begin… - 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.

I believe that it is possible by means of horizontal and vertical lines, constructed 'consciously' but not 'calculating', guided by a higher intuition and brought to harmony and rhythm – I believe that these fundamental aesthetic shapes – where necessary supplemented by lines in other directions or curved lines, make it possible to arrive at a work of art which is as strong as it is true. For anyone who sees more deeply, there is nothing vague about this; it is only vague for the superficial observer of nature. And 'chance' must be as far removed as 'calculation'. And for the rest it seems to me that it is necessary to keep breaking off the horizontal or vertical line: for if these directions were not countered by others, they would themselves come to signify something 'specific' and thus human.

For the present at least I shall restrict my work to the ordinary world of the senses, since that is the world in which we still live. But nevertheless art even now form a transition to the finer regions, which perhaps I am incorrect in calling spiritual, for everything that has form is not yet spiritual, as I read somewhere. But it is nonetheless the path of ascension away from matter. Well dear Querido, with many heartfelt wishes, Piet Mondriaan.
