Guillaume, laughing in his turn, replied to Bertheroy in words which showed how completely he was cured: "You are right," he said, "all ends well since all contributes to truth and justice. Unfortunately, thousands of years are sometimes needed for any progress to be accomplished. . . . However, for my part, I am simply going to put my new explosive on the market, so that those who secure the necessary authorisation may manufacture it and grow rich. Henceforth it belongs to one and all. . . . And I've renounced all idea of revolutionising the world."
But Bertheroy protested. This great official scientist, this member of the Institute laden with offices and honours, pointed to the little motor, and replied with all the vigour of his seventy years: "But that is revolution, the true, the only revolution. It is with things like that and not with stupid bombs that one revolutionises the world! It is not by destroying, but by creating, that you have just done the work of a revolutionist. And how many times already have I not told you that science alone is the world's revolutionary force, the only force which, far above all paltry political incidents, the vain agitation of despots, priests, sectarians and ambitious people of all kinds, works for the benefit of those who will come after us, and prepares the triumph of truth, justice and peace. . . . Ah, my dear child, if you wish to overturn the world by striving to set a little more happiness in it, you have only to remain in your laboratory here, for human happiness can spring only from the furnace of the scientist."
He spoke perhaps in a somewhat jesting way, but one could feel that he was convinced of it all, that he held everything excepting science in utter contempt. He had not even shown any surprise when Pierre had cast his cassock aside; and on finding him there with his wife and child he had not scrupled to show him as much affection as in the past.
Meantime, however, the motor was travelling hither and thither, making no more noise than a bluebottle buzzing in the sunshine. The whole happy family was gathered about it, still laughing with delight at such a victorious achievement. And all at once little Jean, Monsieur Jean, having finished sucking, turned round, displaying his milk-smeared lips, and perceived the machine, the pretty plaything which walked about by itself. At sight of it, his eyes sparkled, dimples appeared on his plump cheeks, and, stretching out his quivering chubby hands, he raised a crow of delight.
Marie, who was quietly fastening her dress, smiled at his glee and brought him nearer, in order that he might have a better view of the toy. "Ah! my darling, it's pretty, isn't it? It moves and it turns, and it's strong; it's quite alive, you see."
The others, standing around, were much amused by the amazed, enraptured expression of the child, who would have liked to touch the machine, perhaps in the hope of understanding it.
"Yes," resumed Bertheroy, "it's alive and it's powerful like the sun, like that great sun shining yonder over Paris, and ripening men and things. And Paris too is a motor, a boiler in which the future is boiling, while we scientists keep the eternal flame burning underneath. Guillaume, my good fellow, you are one of the stokers, one of the artisans of the future, with that little marvel of yours, which will still further extend the influence of our great Paris over the whole world."
These words impressed Pierre, and he again thought of a gigantic vat stretching yonder from one horizon to the other, a vat in which the coming century would emerge from an extraordinary mixture of the excellent and the vile. But now, over and above all passions, ambitions, stains and waste, he was conscious of the colossal expenditure of labour which marked the life of Paris, of the heroic manual efforts in work-shops and factories, and the splendid striving of the young men of intellect whom he knew to be hard at work, studying in silence, relinquishing none of the conquests of their elders, but glowing with desire to enlarge their domain. And in all this Paris was exalted, together with the future that was being prepared within it, and which would wing its flight over the world bright like the dawn of day. If Rome, now so near its death, had ruled the ancient world, it was Paris that reigned with sovereign sway over the modern era, and had for the time become the great centre of the nations as they were carried on from civilisation to civilisation, in a sunward course from east to west. Paris was the world's brain. Its past so full of grandeur had prepared it for the part of initiator, civiliser and liberator. Only yesterday it had cast the cry of Liberty among the nations, and to-morrow it would bring them the religion of Science, the new faith awaited by the democracies. And Paris was also gaiety, kindness and gentleness, passion for knowledge and generosity without limit. Among the workmen of its faubourgs and the peasants of its country-sides there were endless reserves of men on whom the future might freely draw. And the century ended with Paris, and the new century would begin and spread with it. All the clamour of its prodigious labour, all the light that came from it as from a beacon overlooking the earth, all the thunder and tempest and triumphant brightness that sprang from its entrails, were pregnant with that final splendour, of which human happiness would be compounded.
Marie raised a light cry of admiration as she pointed towards the city. "Look! just look!" she exclaimed; "Paris is all golden, covered with a harvest of gold!"
They all re-echoed her admiration, for the effect was really one of extraordinary magnificence. The declining sun was once more veiling the immensity of Paris with golden dust. But this was no longer the city of the sower, a chaos of roofs and edifices suggesting brown land turned up by some huge plough, whilst the sun-rays streamed over it like golden seed, falling upon every side. Nor was it the city whose divisions had one day seemed so plain to Pierre: eastward, the districts of toil, misty with the grey smoke of factories; southward, the districts of study, serene and quiet; westward, the districts of wealth, bright and open; and in the centre the districts of trade, with dark and busy streets. It now seemed as if one and the same crop had sprung up on every side, imparting harmony to everything, and making the entire expanse one sole, boundless field, rich with the same fruitfulness. There was corn, corn everywhere, an infinity of corn, whose golden wave rolled from one end of the horizon to the other. Yes, the declining sun steeped all Paris in equal splendour, and it was truly the crop, the harvest, after the sowing!
"Look! just look," repeated Marie, "there is not a nook without its sheaf; the humblest roofs are fruitful, and every blade is full-eared wherever one may look. It is as if there were now but one and the same soil, reconciled and fraternal. Ah! Jean, my little Jean, look! see how beautiful it is!"
