This new plastic idea will ignore the particulars of appearance, that is to say, natural form and colour. On the contrary it should find its expression in the abstraction of form and colour, that is to say, in the straight line and the clearly defined primary colour.

If you follow nature you will not be able to vanquish the tragic in any real degree in your art... We must free ourselves from our attachment to the external, for only then do we transcend the tragic, and are enabled consciously to contemplate the repose which is within all things.

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, 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.

To approach the spiritual in art, one will make as little use as possible of reality, because reality is opposed to the spiritual.

Art on the contrary sought this harmony in practice [of art itself]. More and more in its creations it has given inwardness to that what surrounds us in nature, until, in Neo-Plasticism, nature is no longer dominant. This achievement of balance may prepare the way for the fulfillment of man and signal the end of (what we call) art.

In art the search for a content which is collectively understandable is false; the content will always be individual.

The essence of painting has actually always been to make it [the universal] plastically perceptible through colour and line.
