It was during this early period of experiment that I first went to Paris. The time was around 1910 when Cubism was in its beginnings. I admired Matis… - Piet Mondrian

And finally I must tell you that I was influenced [in Paris, c. 1912/13] by seeing the work of Picasso, whom I 'greatly' admire. I am not ashamed to speak of his influence, for I believe that it is better to be receptive to correction than to be satisfied with one's own imperfection, and to think that one is O so original! Just as so many painters think. And besides, I am surely totally different from Picasso, as one is generally wont to say.

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

Only now I become conscious that my work in black, white and little color planes has been merely 'drawing' in oil color. In drawing, the lines are the principal means of expressions.. .In painting, however, the lines are absorbed by the color planes; but the limitations of the planes show themselves as lines and conserve their great value.
