“...an animal, at the end of a few months, is what it will be all its life; and its species, at the end of a thousand years, is what it was in the first of those thousand years. Why is man alone subject to becoming an imbecile?”

“The indolence I love is not that of a lazy fellow who sits with his arms across in total inaction, and thinks no more than he acts, but that of a child which is incessantly in motion doing nothing, and that of a dotard who wanders from his subject. I love to amuse myself with trifles, by beginning a hundred things and never finishing one of them, by going or coming as I take either into my head, by changing my project at every instant, by following a fly through all its windings, in wishing to overturn a rock to see what is under it, by undertaking with ardor the work of ten years, and abandoning it without regret at the end of ten minutes; finally, in musing from morning until night without order or coherence, and in following in everything the caprice of a moment.”

“To live is not to breathe but to act. It is to make use of our organs, our senses, our faculties, of all the parts of ourselves which give us the sentiment of our existence. The man who has lived the most is not he who has counted the most years but he who has most felt life.”

“What good would it be to possess the whole universe if one were its only survivor?”

“[T]he man who meditates is a depraved animal.”

“The real world has its limits; the imaginary world is infinite. Unable to enlarge the one, let us restrict the other, for it is from the difference between the two alone that are born all the pains which make us truly unhappy.”

“What, then, is the government? An intermediary body established between the subjects and the sovereign for their mutual communication, a body charged with the execution of the laws and the maintenance of freedom, both civil and political.”
