If we turn to profane history and take any historical work, we find that the facts are told in such a way that they seem to us beyond dispute. But if we see the same facts from the pen of another historian, we no longer recognize them. The reason is that a writer almost never undertakes the task of wrestling with the giant, History, unless he is impelled to do so by a preconceived idea, by a general conception, or a system he wants to establish. And whether he wants to or not, he sees the facts in a light favorable to his preconceived idea, and observes them through prisms which increase or diminish their importance at his will. Then, however great his discernment and however strong his desire to reach the truth, it is doubtful if he ever will. In history, as elsewhere, absolute truth escapes mankind. Louis XIV, Louis XV, Madame de Maintenon, Madame de Pompadour, Louis XVI, even Napoleon and Josephine, so near our own times, are already quasi-mythical characters. The Louis XIII of _Marion de Lorme_ seemed until very lately to be accurate, but recent discoveries show us that he was quite different.
