VIII. The study of the relations between simultaneous facts consists in a search for the connections between all the facts of different species which occur in a given society. We have a vague consciousness that the different habits which are separated by abstraction and ranged under different categories (art, religion, political institutions), are not isolated in reality, that they have common characteristics, and that they are closely enough connected for a change in one of them to bring about a change in another. This is a fundamental idea of the Esprit des Lois of Montesquieu. This bond of connection, sometimes called consensus, has received the name of Zusammenhang from the German school. From this conception has arisen the theory of the Volksgeist (the mind of a people), a counterfeit of which has within the last few years been introduced into France under the name of "âme nationale." This conception is also at the bottom of the theory regarding the soul of society which Lamprecht has expounded.
After the rejection of these mystical conceptions there remains a vague but incontrovertible fact, the "solidarity" which exists between the different habits of one and the same people. In order to study it with precision it would be necessary to analyse it, and a connecting bond cannot be analysed. It is thus quite natural that this part of social science should have remained a refuge for mystery and obscurity.
By the comparison of different societies which resemble or differ from each other in a given department (religion or government), with the object of discovering in what other departments they resemble or differ from each other, it is possible that interesting empirical results might be obtained. But, in order to explain the consensus, it is necessary to work back to the facts which have produced it, the common causes of the various habits. We are thus obliged to undertake the investigation of causes, and we enter the province of what is called philosophical history, because it investigates what was formerly called the philosophy of facts—that is to say, their permanent relations.
IX. The necessity of rising above the simple determination of facts in order to explain them by their causes, a necessity which has governed the development of all the sciences, has at length been felt even in the study of history. Hence have arisen systematic philosophies of history, and attempts to discover historical laws and causes. We cannot here enter into a critical examination of these attempts, which the nineteenth century has produced in so great number; we shall merely indicate what are the ways in which the problem has been attacked, and what obstacles have prevented a scientific solution from being reached.
The most natural method of explanation consists in the assumption that a transcendental cause, Providence, guides the whole course of events towards an end which is known to God.[209] This explanation can be but a metaphysical doctrine, crowning the work of science; for the distinguishing feature of science is that it only studies efficient causes. The historian is not called upon to investigate the first cause or final causes any more than the chemist or the naturalist. And, in fact, few writers on history nowadays stop to discuss the theory of Providence in its theological form.
But the tendency to explain historical facts by transcendental causes survives in more modern theories in which metaphysic is disguised under scientific forms. The historians of the nineteenth century have been so strongly influenced by their philosophical education that most of them, sometimes unconsciously, introduce metaphysical formulæ into the construction of history. It will be enough to enumerate these systems, and point out their metaphysical character, so that reflecting historians may be warned to distrust them.
The theory of the rational character of history rests on the notion that every real historical fact is at the same time "rational"—that is, in conformity with an intelligible comprehensive plan; ordinarily it is tacitly assumed that every social fact has its raison d'être in the development of society—that is, that it ends by turning to the advantage of society; hence the cause of every institution is sought for in the social need it was originally meant to supply.[210] This is the fundamental idea of Hegelianism, if not with Hegel, at least with the historians who have been his disciples (Ranke, Mommsen, Droysen, in France Cousin, Taine, and Michelet). This is a lay disguise of the old theological theory of final causes which assumes the existence of a Providence occupied in guiding humanity in the direction of its interests. This is a consoling, but not a scientific a priori hypothesis; for the observation of historical facts does not indicate that things have always happened in the most rational way, or in the way most advantageous to men, nor that institutions have had any other cause than the interest of those who established them; the facts, indeed, point rather to the opposite conclusion.
From the same metaphysical source has also sprung the Hegelian theory of the ideas which are successively realised in history through the medium of successive peoples. This theory, which has been popularised in France by Cousin and Michelet, has had its day, even in Germany, but it has been revived, especially in Germany, in the form of the historical mission (Beruf) which is attributed to peoples and persons. It will here be enough to observe that the very metaphors of "idea" and "mission" imply a transcendental anthropomorphic cause.
From the same optimistic conception of a rational guidance of the world is derived the theory of the continuous and necessary progress of humanity. Although it has been adopted by the positivists, this is merely a metaphysical hypothesis. In the ordinary sense of the word, "progress" is merely a subjective expression denoting those changes which follow the direction of our preferences. But, even taking the word in the objective sense given to it by Spencer (an increase in the variety and coordination of social phenomena), the study of historical facts does not point to a single universal and continuous progress of humanity, it brings before us a number of partial and intermittent progressive movements, and it gives us no reason to attribute them to a permanent cause inherent in humanity as a whole rather than to a series of local accidents.[211]
Attempts at a more scientific form of explanation have had their origin in the special branches of history (of languages, religion, law). By the separate study of the succession of facts of a single species, specialists have been enabled to ascertain the regular recurrence of the same successions of facts, and these results have been expressed in formulæ which are sometimes called laws (for example, the law of the tonic accent); these are never more than empirical laws which merely indicate successions of facts without explaining them, for they do not reveal the efficient cause. But specialists, influenced by a natural metaphor, and struck by the regularity of these successions, have regarded the evolution of usages (of a word, a rite, a dogma, a rule of law), as if it were an organic development analogous to the growth of a plant; we hear of the "life of words," of the "death of dogmas," of the "growth of myths." Then, in forgetfulness of the fact that all these things are pure abstractions, it has been tacitly assumed that there is a force inhering in the word, the rite, the rule, which produces its evolution. This is the theory of the development (Entwickelung) of usages and institutions; it was started in Germany by the "historical" school, and has dominated all the special branches of history. The history of languages alone has succeeded in shaking off its influence.[212] Just as usages have been treated as if they were existences possessing a separate life of their own, so the succession of individuals composing the various bodies within a society (royalty, church, senate, parliament) has been personified by the attribution to it of a will, which is treated as an active cause. A world of imaginary beings has thus been created behind the historical facts, and has replaced Providence in the explanation of them. For our defence against this deceptive mythology a single rule will suffice: Never seek the causes of an historical fact without having first expressed it concretely in terms of acting and thinking individuals. If abstractions are used, every metaphor must be avoided which would make them play the part of living beings.
