Ribot has pointed out, the sentiments are what is strongest in us, representing the elements of permanence and continuity. It is not less difficult to inventory the contradictions of others, where a single individual is concerned; for here we come up against hypocrisy which has, precisely, as its social rôle, to dissimulate the too strident clash of our variegated convictions. We should then question all men--that is to say, the human entity--or at least groups of men sufficiently numerous for the cynicism of some to compensate the hypocrisy of others. In the lower animal regions and in the vegetable world, budding is one of the ways in which life is created. Scission is seen to take place equally in the world of ideas; but the result, instead of being a new life, is a new abstraction. All general grammars, or elementary treatises on logic, teach how abstractions are formed. They have neglected to teach how they are not formed--that is, why a given commonplace persists in living on without posterity. It is a somewhat delicate question, but it would suggest interesting remarks for a chapter to be called "Refractory commonplaces, or the impossibility of disassociating certain ideas." It would, perhaps, be useful to examine first how ideas become associated, and to what end. The method of this operation is of the simplest sort. Its principle is analogy. There are very remote analogies; there are others so close that they lie within reach of all. A great many commonplaces have an historic origin. One day two ideas became united under the influence of events, and this union proved more or less lasting. Having seen with its own eyes the death-struggle of Byzantium, Europe coupled these two ideas, Byzantium-Decadence, which became a commonplace, an incontestable truth for all men who read and write, and thus necessarily for all the rest--for those who cannot verify the truths offered them. From Byzantium, this association of ideas was extended to the whole Roman Empire, which is now, for sage and respectful historians, nothing but a succession of decadences. We read recently in a weighty newspaper: "If the despotic form of government possessed a special virtue, conducive to the creation of good armies, would not the establishment of the empire have inaugurated an era of development in the military power of the Romans? It was, on the contrary, a signal for downfall and destruction." This commonplace, of Christian origin, has been popularized, in modern times, as everyone knows, by Montesquieu and Gibbon. It has been magisterially disassociated by M. Gaston Paris, and is now nothing but nonsense. But, as its genealogy is known--as its birth and its death have been witnessed--it may serve fairly well as an example to explain the nature of a great historic truth.
