But thinking of it as Matter or Nature, this naturalistic and materialistic travesty, which at first seems odious or ridiculous, of the problems and conceptions of romanticism, of the idea into cause, of development into evolution, of the spirit into mass and the like, to which one would at first be inclined to attribute the inferiority of positivistic historiography, is, on the contrary, for the close observer the progress made by it upon romanticism. That travesty contains the energetic negation of history as moved by extramundane forces, by external finalities, by transcendental laws, just both in its motive and in its general tendency, and the correlative affirmation that its law must be sought in reality, which is one and is called 'nature.' The positivism, which on no account wished to hear anything of 'metaphysic,' had in mind the dogmatic and transcendental metaphysic, which had filtered into the thought of Kant and of his successors; and the target of its contempt was a good one, although it ended by confusing metaphysic with philosophy in general, or dogmatic with critical metaphysic, the metaphysic of being with that of the mind, and was not itself altogether free from that which it undertook to combat. But this does not prevent its repugnance to 'metaphysic' and, restricting ourselves to what is our more immediate interest, to the 'philosophy of history' from having produced durable results. Thanks to positivism historical works became less naïve and richer in facts, especially in that class of facts which romanticism had neglected, such as the dispositions that are called natural, the processes that are called degenerative or pathological, the spiritual complications that are called psychological illusions, the interests that are called material, the production and the distribution of wealth, or economic activity, the facts of force and violence, or of political and revolutionary power. Positivism, intent upon the negation of transcendency and upon the observation of what appertained to it, felt itself to be, and was in that respect, in the right. And each one of us who pays due attention to that order of things and renews that negation is gathering the fruit of positivism, and in that respect is a positivist. Its very contradictions had the merit of making more evident the contradictions latent in romantic historiography. This merit must be admitted to the most extravagant doctrines of the positivists, such as that of Taine, that knowledge is a true hallucination and that human wisdom is an accident (_une rencontre_), which presumed irrationality to be the normal condition, much as Lombroso believed that genius is madness. Another instance of this is the attempt to discover in what way heterogeneity and historical diversity come into existence, if homogeneity is posited; and again the methodical canon that the explanation of history is to be found in causality, but is to stop at genius and virtue, which are
