As I have said several times, ideas do not fall from heaven, and even those which, at a given moment arise from definite situations with the impetuosity of faith and with a metaphysical garb, carry always within themselves the index of their correspondence with the order of the facts, of which the explanation is sought or attempted. The idea of progress, as the unifier of history, appears with violence and becomes a giant in the eighteenth century, that is to say, in the heroic period of the intellectual and political life of the revolutionary bourgeoisie. Just as this engendered, in the order of its works, the most intensive period of history that is known, it also produced its own ideology in the notion of progress. This ideology in its substance means that capitalism is the only form of production which is capable of extending all over the earth and of reducing the whole human race to conditions which resemble each other everywhere. If modern technique can be transported everywhere, if all the human race appear on a single field of competition and all the world as a single market, what is there astonishing in the ideology which, reflecting intellectually these conditions of fact, reaches the affirmation that the present historical unity has been prepared by everything which precedes it? Translating this concept of pretended _preparation_ into the altogether natural concept of _successive condition_, and there is opened before us the road by which the passage is made from the ideology of progress to historical materialism; and now we arrive at the affirmation of Marx, that this form of bourgeois production is the last antagonistic form of the _processus_ of society.
The miracles of the bourgeois epoch, in the unification of the social _processus_, find no parallel in the past. Here are the whole New World, Australia, Northern Africa, and New Zealand! And they all resemble us! And the rebound in the extreme East is made through imitation, and in Africa through conquest! In the presence of this universality and this cosmopolitanism, the acquisition of the Celts and the Iberians to Roman civilization, and of the Germans and that the Slavs to the cycle of Roman Byzantine Christian civilization shrink into insignificance. This ever-growing unification is reflected more every day in the political mechanism of Europe; this mechanism, because founded on the economic conquest of the other parts of the world, oscillates henceforth with the flux and reflux which come from the most distant regions. In this most complicated mingling of action and reactions the war between Japan and China, made with methods imitated, or directly borrowed, from European technique, leaves its traces, deep and far-reaching, in the diplomatic relations of Europe, and still clearer traces in the stock exchange, which is the faithful interpreter of the consciousness of our time. This Europe, mistress of all the rest of the world, has recently seen the relations of the politics of the states of which it is composed oscillate in consequence of a revolt in the Transvaal, and in consequence of the ill success of the Italian armies in Abyssinia in these last days.[30]
