Money quote:

When, in the year 1913, in my desperate attempt to free art from the ballast of objectivity, I took refuge in the square form and exhibited a picture which consisted of nothing more than a black square on a white field, the critics and, along with them, the public sighed, “Everything which we loved is lost. We are in a desert …. Before us is nothing but a black square on a white background!”
