It is a grave error to expect to find in facts the basis of a primitive and exclusive law: facts may be made to demonstrate anything. The most opposite parties have fallen into the same error in this respect. Whoever has discovered, at the origin of a state, an act of violence in conformity to his preconceived opinion, takes it as the foundation of what he calls the general law. Some fancy they can discern absolute and well-regulated hereditary succession in the midst of barbarism; others transfer the troubles and violence of a barbarian election into a more advanced stage of civilization; whatever they find existing as _fact_ in the infancy of society, they convert into _law_ for society in its greatest extension and development. This is neither philosophy nor history. The ruling _law_ is that which is conformable to reason and justice. There is always more or less of this law at every epoch in the life of human society; but at no epoch is it pure or complete. We must resign ourselves to the task of freeing it everywhere from all alloy. Let us then pass by the primitive and exclusive right of royal heredity, which existed neither among the Franks nor in other countries; all that can be said is that the principle of hereditary monarchy tended, early and constantly, to prevail. The heirship of the private domain of the kings, which was of considerable value, powerfully contributed to establish the heirship of the kingdom, just as the partition of the private domain among the sons led to the partition of the royal dominions; but the partition of the kingdom was almost always made with the consent of the nobles, whilst the heirship of the crown, in each state, does not appear to have required their formal assent. {160} Fall Of The Merovingians.
