Why did a figure such as Leibniz fail to use his own tools? Perhaps messiness was the source of his creativity. This is a fact of intellectual originality with which Google must still grapple—libraries, after all, allow for the type of manageable disorder which is often the spark of creativity. Or maybe Leibniz resisted the very order of things, over which his calculus gave him a unique mastery. If anything, the rejection of systematized information handling methods could be as common as their adoption.
