All painting - the painting of the past as well as of the present - shows us that its essential plastic means were only line and color.

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.

It is a task of art to express clear vision of reality.

The position of the artist is humble. He is essentially a channel.

Evolution is always the work of pioneers, and their followers are always small in number. This following is not a clique; it is the result of all the existing social forces; it is composed of all those who through innate or acquired capacity are ready to represent the existing degree of human revolution.

The truly modern artist is aware of abstraction in an emotion of beauty.

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.
