“New storms will arise; one can believe in calamities to come which will surpass the afflictions we have been overwhelmed by in the past; already, men are thinking of bandaging their old wounds to return to the battlefield.”
Book XLII: Ch. 18: A summary of the changes which have occurred around the globe in my lifetime
Mémoires d'outre-tombe (1848 – 1850)
Context: New storms will arise; one can believe in calamities to come which will surpass the afflictions we have been overwhelmed by in the past; already, men are thinking of bandaging their old wounds to return to the battlefield. However, I do not expect an imminent outbreak of war: nations and kings are equally weary; unforeseen catastrophe will not yet fall on France: what follows me will only be the effect of general transformation. No doubt there will be painful moments: the face of the world cannot change without suffering. But, once again, there will be no separate revolutions; simply the great revolution approaching its end. The scenes of tomorrow no longer concern me; they call for other artists: your turn, gentlemen!
As I write these last words, my window, which looks west over the gardens of the Foreign Mission, is open: it is six in the morning; I can see the pale and swollen moon; it is sinking over the spire of the Invalides, scarcely touched by the first golden glow from the East; one might say that the old world was ending, and the new beginning. I behold the light of a dawn whose sunrise I shall never see. It only remains for me to sit down at the edge of my grave; then I shall descend boldly, crucifix in hand, into eternity.

Context: We learn by such results as these, what is the kind of education that science offers to man. It teaches us to be neglectful of nothing, not to despise the small beginnings — they precede of necessity all great things. Vesicles make clouds; they are trifles light as air, but then they make drops, and drops make showers, rain makes torrents and rivers, and these can alter the face of a country, and even keep the ocean to its proper fulness and use. It teaches a continual comparison of the small and great, and that under differences almost approaching the infinite, for the small as often contains the great in principle, as the great does the small; and thus the mind becomes comprehensive. It teaches to deduce principles carefully, to hold them firmly, or to suspend the judgment, to discover and obey law, and by it to be bold in applying to the greatest what we know of the smallest. It teaches us first by tutors and books, to learn that which is already known to others, and then by the light and methods which belong to science to learn for ourselves and for others; so making a fruitful return to man in the future for that which we have obtained from the men of the past.

As quoted in The Quotable Woman (1978) by Elaine T Partnow, p. 226. "When men destroy their old gods they will find new ones to take their place" has sometimes been quoted as her original statement, though she states that she herself is quoting an abbot.
