Aussitôt qu'une pensée vraie est entrée dans notre esprit, elle jette une lumière qui nous fait voir une foule d'autres objets que nous n'apercevions pas auparavant. 
As quoted in A Dictionary of Thoughts: Being a Cyclopedia of Laconic Quotations from the Best Authors of the World, both Ancient and Modern (1908) by Tyron Edwards.

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.
                                    
                                        
                                        L’écrivain original n’est pas celui qui n’imite personne, mais celui que personne ne peut imiter.
