Odilon Redon wrote in a letter to Charles Morice, 1911:
I am capricious. I float along on the infinite combination of the materials I touch. I believe that the artist yields to the stimulus of materials that will transport his spirit. I am sure of what I will not do, but not of what my art will bring about. I await joyous surprises while working, an awakening of the materials that I put to work and that my spirit develops.
A good work of art, made in one burst with tenacity, determination, passion as much as reason, should surpass the goal the artists has set for himself.
