“ It must be a universal law of nature."
"Alas! We only live through 500 revolutions around the sun," said the Saturnian. (This translates to about 15,000 years, by our standards.) "You can see yourself that this is to die almost at the moment one is born; our existence is a point, our lifespan an instant, our planet an atom. Hardly do we begin to learn a little when death arrives, before we get any experience. ”

“ I have been to countries where they live a thousand times longer than we do, and they also die. But people everywhere have the good sense to know their role and to thank the Author of nature. He has scattered across this universe a profusion of varieties with a kind of admirable uniformity. For example, all the thinking beings are different, and all resemble one another in the gift of thought and desire. Matter is extended everywhere, but has different properties on each planet. ”

“ Tell me how many senses the men of your planet have."
"We only have 72," said the academic, "and we always complain about it. Our imagination surpasses our needs. We find that with our 72 senses, our ring, our five moons, we are too restricted; and in spite of all our curiosity and the fairly large number of passions that result from our 72 senses, we have plenty of time to get bored."
"I believe it," said Micromegas, "for on our planet we have almost 1,000 senses; and yet we still have a kind of vague feeling, a sort of worry, that warns us that there are even more perfect beings. ”
