Book 12

But some of those who have the reputation of approaching history in a reasonable spirit are like the theoretical physicians. They spend all their time in libraries, and acquire generally all the learning which can be got from books, and then persuade themselves that they are adequately equipped for their task. . . . Yet in my opinion they are only partially qualified for the production of genuine history. To inspect ancient records indeed, with the view of ascertaining the notions entertained by the ancients of certain places, nations, polities and events, and of understanding the several circumstances and contingencies experienced in former times, is useful; for the history of the past directs our attention in a proper spirit to the future, if a writer can be found to give a statement of facts as they really occurred. But to persuade one’s self, as Timaeus does, that such ability in research is sufficient to enable a man to describe subsequent transactions with success is quite foolish. It is as though a man were to imagine that an inspection of the works of the old masters would enable him to become a painter and a master of the art himself.
