"Do you know where we are? Do you know how we reached here?
"We are—on the threshold of the infinite, as we were when on the Earth. We have not advanced one step!"
*****
A deep emotion had taken possession of my mind. Urania's last words had pierced my very marrow like an icy chill. "Never any end—never! never," I repeated; I could think or speak of nothing else. But still the magnificence of the spectacle appealed to my eyes, and my feeling of annihilation gave place to enthusiasm.
"Astronomy," I cried, "is everything! To know these things, to live in the infinite,—oh, Urania! what are other human ideas compared with science? Shadows, phantoms!"
"Oh! you will wake up again upon the Earth," she said; "you will admire, and rightly too, the wisdom of your masters. But understand this,—the astronomy of your schools and observatories, mathematical astronomy, the beautiful science as known to Newton, Laplace, Le Verrier, is not yet definite, actual knowledge.
"That, O my son! is not the end which I have pursued since the days of Hipparchus and Ptolemy. Look at the thousands of suns analogous to that which gives life to the earth, which like it are sources of light, motion, activity, and splendor! Ah! that is the object of the science to come,—the study of universal and eternal life. Until now, no one has ever entered the temple. Figures are not an end, but a means; they do not represent Nature's structure, only the methods, the scaffoldings. You are to see the dawn of a new day. Mathematical astronomy will yield her place to physical astronomy, to the true study of Nature.
"Yes," she continued, "astronomers who calculate the movements of the stars in their daily passage of the meridian, those who foretell eclipses, celestial phenomena, periodical comets, who observe the exact positions of the stars and planets on the different degrees of the celestial sphere so carefully; those who discover comets, planets, satellites, and variable stars; those who investigate and determine the disturbance caused the Earth's motion by attraction from the Moon and planets; those who consecrate their night-watches to the discovery of the fundamental elements of the world's system,—are all of them calculators and observers, precursors of the new astronomy. These are immense labors, studies worthy of admiration, and important works which bring to light the highest faculties of the human mind. But it is the army of the past; mathematicians and geometricians. Henceforth, the hearts of savants will throb for a still nobler conquest. All these great minds never really left the Earth while studying the skies. Astronomy's aim is not to show us the apparent position of shining specks, nor to weigh stones moving through space, nor to foretell eclipses, or the phases of the Moon or tides. All this is fine, but it is not enough.
"If life did not exist upon the earth, that planet would be absolutely devoid of interest for any mind whatsoever; and the same remark is applicable to all the worlds which gravitate around the thousands of millions of suns in the wide stretches of immensity. Life is the object of the whole creation. If there were neither life nor thought, it would all be null and void.
"You are destined to witness an entire transformation in science. Matter will give place to mind."
