The work of art should be entirely conceived and formed by the mind before its execution. It should receive nothing from Nature's formal properties or from sensuality or sentimentality.... The picture should be constructed entirely from purely plastic elements, that is to say, planes and colours. A pictorial element has no other significance than 'itself', and therefore the picture has no other significance than 'itself'.
