Old men, for the most part, are like old chronicles that give you dull but true accounts of times past, and are worth knowing only on that score.
We document, explain, justify, construct, organize: these are good things, but we do not succeed in coming to the whole. But we may as well calm down: construction is not absolute. Our virtue is this: by cultivating the exact we have laid the foundations for a science of art, including the unknown X.
