The conception of the history of man as a causal development meant the elevation of historical inquiry to the dignity of a science. Just as the study of bees cannot become scientific so long as the student's interest in them is only to procure honey or to derive moral lessons from the labors of "the little busy bee," so the history of human societies cannot become the object of pure scientific investigation so long as man estimates its value in pragmatical scales. Nor can it become a science until it is conceived as lying entirely within a sphere in which the law of cause and effect has unreserved and unrestricted dominion. On the other hand, once history is envisaged as a causal process, which contains within itself the explanation of the development of humanity from its primitive state to the point that it has reached, such a process necessarily becomes the object of scientific investigation and the interest in it is scientific curiosity.

At the same time, the instruments were sharpened and refined. Here Wolf, a philologist with historical instinct, was a pioneer. His Prolegomena to Homer (1795) announced new modes of attack. Historical investigation was soon transformed by the elaboration of new methods.

"Progress" involves a judgment of value, which is not involved in the conception of history as a "genetic" process. It is also an idea distinct from that of evolution. Nevertheless, it is closely related to the ideas that revolutionized history at the beginning of the last century; it swam into people's ken simultaneously; and it helped effectively to establish the notion of history as a continuous process and to emphasize the significance of time. Passing over earlier anticipations, I may point to a Discours of Turgot (1750), where history is presented as a process in which "the total mass of the human race" "marches continually though sometimes slowly to an ever increasing perfection." That is a clear statement of the conception which Turgot's friend Condorcet elaborated in the famous work, published in 1795, Esquisse d'un tableau historique des progrès de l'esprit humain. This work first treated with explicit fullness the idea to which a leading role was to fall in the ideology of the nineteenth century. Condorcet's book reflects the triumphs of the Tiers état, whose growing importance had also inspired Turgot; it was the political changes in the eighteenth century that led to the doctrine, emphatically formulated by Condorcet, that the masses are the most important element in the historical process. I dwell on this because, though Condorcet had no idea of evolution, the predominant importance of the masses was the assumption that made it possible to apply evolutional principles to history. And it enabled Condorcet himself to maintain that the history of civilization, a progress still far from being complete, was a development conditioned by general laws.

The assimilation of society to an organism, which was a governing notion in the school of Savigny, and the conception of progress, combined to produce the idea of an organic development, in which the historian has to determine the central principle or leading character. This is illustrated by the apotheosis of democracy in Tocqueville's Démocratie en Amérique, where the theory is maintained that "the gradual and progressive development of equality is at once the past and the future of the history of men." The same two principles are combined in the doctrine of Spencer (who held that society is an organism, though he also contemplated its being what he calls a "super-organic aggregate"), that social evolution is a progressive change from militarism to industrialism.
