To understand the interlacings and the complexus in its inner connection and its outer manifestations; to descend from the surface to the foundation, and then to return from the foundation to the surface; to analyze the passions and the intentions, in their motives, from the closest to the most remote, and then to bring back the data of the passions and of the intentions and of their causes to the most remote elements of a definite economic situation; there is the difficult art which the materialistic conception must realize.

And as we must not imitate that teacher who on the bank taught his pupils to swim by the definition of swimming, I beg the reader to await the examples which I shall give in other essays in a real historical narration, working over into a book which for some time I have already been doing in my teaching.

In this way certain secondary and derivative questions are once for all cleared up.

What, for example, is the meaning of the lives of the great men?

In these later times, answers have been given, which, in one sense or another, have an extreme character. On the one side, there are the extreme sociologists, on the other side the individualists who, after the fashion of Carlyle, put the heroes into the first rank of their history. According to some it is sufficient to show what were the reasons, for example, of Cæsarism, and Cæsar matters little. According to others, there are no objective reasons of classes and social interests which suffice to explain anything; it is the great minds which give the impulse to the whole historic movement; and history has, so to speak, its lords and its monarchs. The empiricists of narration extract themselves from embarrassment in a very simple fashion, putting together at hazard men and things, objective necessities of fact and subjective influences.

Historical materialism goes beyond the antithetical views of the sociologists and the individualists, and at the same time it eliminates the eclecticism of the empirical narrators.

All this is completely accidental with relation to the general course of things which was pushing the new class, mistress of the field, to save from the Revolution that which appeared to it necessary to save, and that necessitated the creation of a bureaucratico-military government. It was, however, necessary to find the man, or the men. But what actually happened came about in the fashion that we know. It depended on this fact, that it was Napoleon who directed the enterprise and not a pitiable Monk, or a ridiculous Boulanger. And from that moment the accident ceases to be accident, precisely because it is this definite person who gives his imprint and physiognomy to the events, determining the fashion or the manner in which they have unfolded.
