This is evident from the range of themes alone; but it is clear in the painterly qualities as well. He draws or colors; he composes or follows his immediate sensation of nature; he paints with a virile brush solidly, or in the most delicate sparse watercolor, and is equally sure in both. He possessed a firm faith in spontaneous sensibility, in the resources of the sincere self. He can be passionate and cool, grave and light; he is always honest.

"Cézanne's work not only gives us the joy of beautiful painting; it appeals too as an example of heroism in art. For he reached perfection, it is well known, in a long and painful struggle with himself. This struggle can be read in his work in the many signs of destructiveness and black moods, especially in his early phase; perhaps we may recognize it too even in the detached aspect of the world that he finally shapes into a serenely ordered whole. I do not doubt that the personal content of this classic art will in time become as evident as the aesthetic result."
