He claims that this method of working, which is his alone, is the only correct one, the only one leading to a serious result. He mercilessly condemns all preference for simplification which does not pass through submission to nature by means of a meditative and progressive analysis. If a painter is easily satisfied, it is because, according to Paul Cézanne, his vision is mediocre, his temperament practically worthless.
Leonardo da Vinci put forth a similar idea in his treatise on painting when he said, "The painter who has no doubts will profit little from his studies. When a work of art surpasses the judgment of the creator, he who works advances little; but when his judgment rules his works, those works become more and more perfect if inconsistency does not interfere." The artist will arrive at self-knowledge and the perfection of his art not through patience, therefore, but through love that gives insight and the desire to analyze in greater depth and to improve. He must extract from Nature an image which will be, properly speaking, his own; and only through analysis, if he has the strength to press it to the end, will he make himself known ultimately, unambiguously, abstractly.
