"Nothing is so difficult to understand as that of which one is ignorant, nothing more simple than what one knows. Who is surprised now to see that the electric telegraph instantly sends human thought across continents and seas? Who is surprised to see lunar attraction raise the waters of the ocean and produce tides? Who is surprised to see light transmit itself from one star to another at the rate of three hundred thousand kilometres per second? Besides, thinkers alone could appreciate the grandeur of these marvels; the vulgar are surprised at nothing. If some new discovery to-morrow should enable us to make signals to the inhabitants of Mars and receive replies from them, three quarters of mankind would think nothing of it the day after. Yes, the animating forces can transport themselves from one world to the other; not everywhere nor always, to be sure, and not all of them. There are laws and conditions. My will, with the help of my muscles, can raise my arm or throw a stone; if I take a weight of twenty kilos, it will still raise my arm; if I want to raise a weight of a thousand kilos, I can no longer do it. Some minds are incapable of any activity; others have acquired transcendent faculties. Mozart at six years of age surprised all his hearers by the power of his musical genius, and at eight published his first two sonatas; while the greatest dramatic author who ever existed, Shakspeare, had written nothing worthy of his name until after he was thirty years old. It is not necessary to believe that the soul should belong to some supernatural world. Everything is in Nature. It is hardly more than a hundred thousand years since terrestrial humanity evolved itself from the animal chrysalis. For millions of years, during the long historic series of the primary, secondary, and tertiary periods, there was not a single eye on the earth to see these grand sights, a single human mind to contemplate them. Progress has slowly raised the inferior souls of plants and animals; man is quite recent on the planet. Nature is in ceaseless progress, the universe is a perpetual growth, ascent is the supreme law.
"All worlds," he added, "are not actually inhabited. Some are at the dawn, others at twilight. For example, in our solar system, Mars, Venus, Saturn, and several of his satellites seem to be in full vital activity. Jupiter appears not to have passed its primary period; the Moon has perhaps no longer any inhabitants. Our own period is of no more importance in the general history of the universe than one anthill in the infinite. Before the existence of the earth, there had been, from all eternity, worlds peopled with humanities. When our planet shall have ceased to live, and the last human family shall have fallen asleep on the brink of the last lagoon of the frozen ocean, numberless suns will still shine in the infinite, there will still be mornings and evenings, spring-time and flowers, hopes and joys, other suns, other earths, other humanities,—boundless space, peopled with tombs and cradles. But life, thought, eternal progress, are the final object of creation.
"The earth is a star's satellite. Now, as well as in the future, we are citizens of the sky; whether we know it or not, we are really living in the stars."
Thus the two friends conversed about the deep subjects which engrossed their thoughts; when they were conquering a problem, even if it were incomplete, they experienced a true happiness at having taken another step in their search for the unknown, and could then talk more quietly about the ordinary things of life. They were two minds equally eager for knowledge, imagining in their youthful fervor that they could isolate themselves from the world, look down upon human ideas, and in their celestial flight reach the star of Truth, which shone above their heads in the depths of the infinite.
[IV.]
AMOR.
IN their life together, pleasant and intimate as it was, there was something lacking. These conversations on the serious topics of being or non-being, their exchange of ideas on the analysis of humanity, their inquiries into the final end of the existence of things, satisfied their minds sometimes, but not their hearts. When they had been together for a long time, talking under the garden trellis which towered above the picture of the great city, or in the silent library, the student, the thinker could not leave his companion; they sat hand in hand, mute, attracted and repelled by an irresistible power. After leaving each other, both felt a singular, painful void in their breasts, an indefinable uneasiness, as though some link necessary for both their lives had been broken; and each hoped for nothing but the hour of meeting. He loved her, not for himself, but for herself, with an almost impersonal affection, with a feeling of high esteem as well as ardent love; and by a constantly fought combat with his desire he had been able to resist it. But one day, when they were both sitting on the wide divan in the library, strewn, as usual, with books and loose leaves, a silence fell upon them, and it happened that, overcome perhaps by the weight of his long-continued efforts to resist so powerful an attraction, the young author's head insensibly drooped to his companion's shoulder, and almost at once ... their lips met....
