“If children were brought into the world by an act of pure reason alone, would the human race continue to exist? Would not a man rather have so much sympathy with the coming generation as to spare it the burden of existence, or at any rate not take it upon himself to impose that burden upon it in cold blood?”

“He seriously thought that there is less harm in killing a man than producing a child: in the first case you are relieving someone of life, not his whole life but a half or a quarter or a hundredth part of that existence that is going to finish, that would finish without you; but as for the second, he would say, are you not responsible to him for all the tears he will shed, from the cradle to the grave? Without you he would never have been born, and why is he born? For your amusement, not for his, that’s for sure; to carry your name, the name of a fool, I’ll be bound – you may as well write that name on some wall; why do you need a man to bear the burden of three or four letters?”
― Gustave Flaubert, November

“The idea of bringing someone into the world fills me with horror. I would curse myself if I were a father. A son of mine! Oh no, no, no! May my entire flesh perish and may I transmit to no one the aggravations and the disgrace of existence.”
