Ancient régime, Revolution, new régime, I am going to try to describe these three conditions with exactitude. I have no other object in view. A historian may be allowed the privilege of a naturalist; I have regarded my subject the same as the metamorphosis of an insect. Moreover, the event is so interesting in itself that it is worth the trouble of being observed for its own sake, and no effort is required to suppress one's ulterior motives. Freed from all prejudice, curiosity becomes scientific and may be completely concentrated on the secret forces, which guide the wonderful process. These forces are the situation, the passions, the ideas, the wills of each group of actors, and which can be defined and almost measured. They are in full view; we are not reduced to conjectures about them, to uncertain divination, to vague indications. By singular good fortune we perceive the men themselves, their exterior and their interior. The Frenchmen of the ancient régime are still within visual range. All of us, in our youth, (around 1840-50), have encountered one or more of the survivors of this vanished society. Many of their dwellings, with the furniture, still remain intact. Their pictures and engravings enable us to take part in their domestic life, see how they dress, observe their attitudes and follow their movements. Through their literature, philosophy, scientific pursuits, gazettes, and correspondence, we can reproduce their feeling and thought, and even enjoy their familiar conversation. The multitude of memoirs, issuing during the past thirty years from public and private archives, lead us from one drawing room to another, as if we bore with us so many letters of introduction. The independent descriptions by foreign travelers, in their journals and correspondence, correct and complete the portraits, which this society has traced of itself. Everything that it could state has been stated, except, * what was commonplace and well-known to contemporaries, * whatever seemed technical, tedious and vulgar, * whatever related to the provinces, to the bourgeoisie, the peasant, to the laboring man, to the government, and to the household.
