Historic truth ought to be no less sacred than religion. If the precepts of faith raise our soul above the interests of this world, the lessons of history, in their turn, inspire us with the love of the beautiful and the just, and the hatred of whatever presents an obstacle to the progress of humanity. These lessons, to be profitable, require certain conditions. It is necessary that the facts be produced with a rigorous exactness, that the changes political or social be analysed philosophically, that the exciting interest of the details of the lives of public men should not divert attention from the political part they played, or cause us to forget their providential mission.
