“Nature is an infinite sphere whose center is everywhere and whose circumference is nowhere.”

“Let man then contemplate the whole of nature in her full and lofty majesty, let him turn his gaze away from the lowly objects around him; let him behold the dazzling light set like an eternal lamp to light up the universe, let him see the earth as a mere speck compared to the vast orbit described by this star, and let him marvel at finding this vast orbit itself to be no more than the tiniest point compared to that described by the stars revolving in the firmament. But if our eyes stop there, let our imagination proceed further; it will grow weary of conceiving things before nature tires of producing them. The whole visible world is only an imperceptible dot in nature’s ample bosom. No idea comes near it; it is no good inflating our conceptions beyond imaginable space, we only bring forth atoms compared to the reality of things. Nature is an infinite sphere whose centre is everywhere and circumference is nowhere. In short it is the greatest perceptible mark of God’s omnipotence that our imagination should lose itself in that thought.”

“Nature constantly begins the same things over again, years, days, hours, spaces too. And numbers run end to end, one after another. This makes something in a way infinite and eternal. It is not that any of this is really infinite and eternal, but these finite entities multiply infinitely. Thus only number, which multiplies them, seems to me to be infinite.”

“We naturally believe we are more capable of reaching the centre of things than of embracing their circumference, and the visible extent of the world is visibly greater than we. But since we in our turn are greater than small things, we think we are more capable of mastering them, and yet it takes no less capacity to reach nothingness than the whole. In either case it takes an infinite capacity, and it seems to me that anyone who had understood the ultimate principles of things might also succeed in knowing infinity. One depends on the other, and one leads to the other. These extremes touch and join by going in opposite directions, and they meet in God and God alone.”

“We know the existence of the infinite without knowing its nature, because it too has extension but unlike us no limits.But we do not know either the existence or the nature of God, because he has neither extension nor limits.”

“For after all what is man in nature? A nothing in relation to infinity, all in relation to nothing, a central point between nothing and all and infinitely far from understanding either. The ends of things and their beginnings are impregnably concealed from him in an impenetrable secret. He is equally incapable of seeing the nothingness out of which he was drawn and the infinite in which he is engulfed.”

“When I consider the short duration of my life, swallowed up in the eternity before and after, the little space which I fill, and even can see, engulfed in the infinite immensity of spaces of which I am ignorant, and which know me not, I am frightened, and am astonished at being here rather than there; for there is no reason why here rather than there, why now rather than then. Who has put me here? By whose order and direction have this place and time been allotted to me? Memoria hospitis unius diei prætereuntis.”
