Leo Tolstoy: War and Peace

SECOND EPILOGUE 3. CHAPTER III

A locomotive is moving. Someone asks: "What moves it?" A peasant says the devil moves it. Another man says the locomotive moves because its wheels go round. A third asserts that the cause of its movement lies in the smoke which the wind carries away.

The peasant is irrefutable. He has devised a complete explanation. To refute him someone would have to prove to him that there is no devil, or another peasant would have to explain to him that it is not the devil but a German, who moves the locomotive. Only then, as a result of the contradiction, will they see that they are both wrong. But the man who says that the movement of the wheels is the cause refutes himself, for having once begun to analyze he ought to go on and explain further why the wheels go round; and till he has reached the ultimate cause of the movement of the locomotive in the pressure of steam in the boiler, he has no right to stop in his search for the cause. The man who explains the movement of the locomotive by the smoke that is carried back has noticed that the wheels do not supply an explanation and has taken the first sign that occurs to him and in his turn has offered that as an explanation.

The only conception that can explain the movement of the locomotive is that of a force commensurate with the movement observed.

The only conception that can explain the movement of the peoples is that of some force commensurate with the whole movement of the peoples.

Yet to supply this conception various historians take forces of different kinds, all of which are incommensurate with the movement observed. Some see it as a force directly inherent in heroes, as the peasant sees the devil in the locomotive; others as a force resulting from several other forces, like the movement of the wheels; others again as an intellectual influence, like the smoke that is blown away.

So long as histories are written of separate individuals, whether Caesars, Alexanders, Luthers, or Voltaires, and not the histories of all, absolutely all those who take part in an event, it is quite impossible to describe the movement of humanity without the conception of a force compelling men to direct their activity toward a certain end. And the only such conception known to historians is that of power.
