The abstract human mind will have to receive the intended impression by its own means. I always confine myself to expressing the universal, that is, … - Piet Mondrian

And then about whether or not to work from a given in nature. In my view, you [ Van Doesburg ] define this in a rather narrow sense. In the main, I do agree with you that the destruction of the natural, and it reconstruction, must be accomplished according to a spiritual image, but I believe that we should take a broad view here. What is natural does not have to be a representation of something. I'm now working on a thing that is a reconstruction of a starry sky ['Composition, Checkerboard Dark Colours', 1919] and yet I'm making it without a given from nature. Someone who says he uses a theme from nature can be right, but also someone who says he uses nothing at all.

Ru-h-ru-h-ru-h-h-h-h. Pooh-ooh-ooh. Tick-tick-tick-tick. Pre. R-r-r-r-r-uh-h. Huh! Bang. Su-su-su-ur. Booh-a-ah. R-r-r-r. Pooh…multitude of sounds, all mixed together. Motorcars, buses, carts, carriages, people, lamp-posts, trees.. all mixed together; in front of cafés, shops, offices, posters, shop windows: multitude of things. Motion and standstills: different movement. Movement in space and movement in time. Multitude of images and all sorts of ideas. Images are veiled truths. All different truths form what is true. What is individual does not display all in a single image.. ..Ru-ru-ru-u-u. Pre. Images are boundaries. Multitude of images and all sorts of boundaries. Elimination of images and boundaries through all sorts of images. Boundary clouds what is true. Rebus: where is what is true? Boundaries are just as relative as images, as time and space. [Mondrian's poem has strong connections with 'dynamism' of Futurism]
