"In Nature there is neither astronomy nor chemistry nor philosophy nor mechanics; those are subjective methods of observation. There is but a single unit. The infinitely great is identical with the infinitely small. Space is infinite without being great. Time is eternal without being long. Stars and atoms are one.

"The unity of the universe is constituted of invisible, imponderable, immaterial force, which moves atoms. If a single atom should cease to be moved by force, the universe would stop. The earth turns round the sun, the sun gravitates around a sidereal arch, which is itself capable of motion; the millions, the thousand millions of suns which people the universe move much more rapidly than gunpowder projectiles; these stars which seem to us to be motionless are suns thrown into the eternal void at the speed of ten, twenty, thirty millions of kilometres a day, all rushing towards an unknown goal,—suns, planets, earths, satellites, wandering comets ...; the fixed point, the centre of gravity sought after by analysts, flies as fast as it is pursued, and really exists nowhere. The atoms of which bodies are composed, move relatively as fast as stars in the sky. Motion regulates all things, forms all things.
"The atom itself is not an inert mass, it is a centre of force.
"That which essentially constitutes and organizes the human being, is not his material substance; it is not the protoplasm, nor the cell, nor those marvellous and fertile combinations of carbon with hydrogen, oxygen, and nitrogen,—it is animate, invisible, immaterial Force. It is that which groups, directs, and keeps together the innumerable particles which compose the exquisite harmony of the living body.
"Matter and energy have never been seen separated from each other; the existence of one implies the existence of the other; they are perhaps substantially identical.
"If the body should suddenly decay after death, as it slowly disintegrates and perpetually renews itself during life, it would matter little. The soul remains. The organizing cerebral atom is the centre of this force. It also is indestructible.
"What we see is deceitful. The real is the invisible."

He began to pace up and down the floor. The young girl had listened to him as one listens to an apostle, a loved apostle; and although he had really spoken but for her, he had not apparently realized her presence,—she had been so silent and motionless. She went to him and took one of his hands in hers. "Oh!" she cried, "if you have not yet conquered Truth, she cannot elude you."
