“.. You know that I think a society of impressionists would be a good thing of the same nature as the Society of the Twelve English Pre-Raphaelites, and I think that it could come into existence. Then I incline to think that the artists would guarantee mutually among themselves a livelihood, each consenting to give a considerable number of pictures to the Society, and that the gains as well as the losses should be taken in common.”

The Art of Persuasion
Context: I would inquire of reasonable persons whether this principle: Matter is naturally wholly incapable of thought, and this other: I think, therefore I am, are in fact the same in the mind of Descartes, and in that of St. Augustine, who said the same thing twelve hundred years before.... I am far from affirming that Descartes is not the real author of it, even if he may have learned it only in reading this distinguished saint; for I know how much difference there is between writing a word by chance without making a longer and more extended reflection on it, and perceiving in this word an admirable series of conclusions, which prove the distinction between material and spiritual natures, and making of it a firm and sustained principle of a complete metaphysical system, as Descartes has pretended to do.... it is on this supposition that I say that this expression is as different in his writings from the saying in others who have said it by chance, as in a man full of life and strength, from a corpse.
