Strictly speaking, self-sufficiency does not come in degrees. Anything short of sufficiency is insufficiency, and so it makes little sense to say that the experience of great art is "more self-sufficient." But we needn't be strict here, as we are not when we say that an individual is self-sufficient if she works and lives alone, even if she depends on the grocer for food, on her doctor for good health, and so on. So perhaps it can come in degrees. Still, I find Dewey's remarks on the self-sufficiency of an experience (especially) obscure; and since we shall already have much to say about the unity of experience, I have put the matter to one side.
