essence. A proof of this is to be found in the _Historical Philosophy of France_ of Flint. He proceeds from a presumption that is perhaps the opposite of that of Fueter--that is to say, he treats of the philosophy of history, and not of history, but finds it impossible to maintain the dykes between the two. His treatise, therefore, when artificial obstacles have been overcome, runs like a single river and reveals to our view the whole history of historical French thought, to which Bossuet and Rollin, Condorcet and Voltaire, Auguste Comte and Michelet or Tocqueville equally belong. At this point it will probably be objected (although Fueter does not propound this objection, it is probable that it is at the back of his mind) that what is desired in a history of historiography is not so much a history of _historical thought_ as a history of _history in the concrete_: of the _Storie fiorentine_ of Machiavelli, of the _Siècle de Louis XIV_ of Voltaire, or of the _Römische Geschichte_ of Niebuhr: that would be a general history, while what is desired is a specific history. But it is well to pay close attention to the meaning of such a request and to the possibility of what is asked. If I set out to write the history of the _Storie fiorentine_ of Machiavelli, in respect to the particular material with which it deals, I shall rewrite the history of Florence, criticizing and completing Machiavelli, and shall thus be, for instance, a Villari, a Davidsohn, or a Salvemini. If I set out to write the history of the material of Voltaire's work, I shall criticize Voltaire and outline a new _Siècle de Louis XIV_, as has been done, for example, by Philippson. And if I set to work to examine and rethink the work of Niebuhr in respect to its particular material, I shall be a new historian of Rome, a Mommsen or (to quote the most recent writers) a Hector Pais or a Gaetano de Sanctis. But is this what is desired? Certainly not. But if this be not desired, if the particular materials of those histories are not to be taken account of, what else remains save the 'way' in which they have been conceived, the 'mental form' by means of which they construct their narratives, and therefore their theory and their historical 'thought'?
