"Answer without flinching: if there existed a solution that could abolish the totality of all evils inflicted on disastrous humanity, if it was possible, by some simple remedy, incredibly cheap, immediately accessible, scrupulously inoffensive, of absolute and definitive efficiency, to stop all distress, all cries, all cries of pain, all pathologies, all protests of ill-being, all despair, all cataclysms, all anxiety, all unhappiness, in short all tortures afflicting the human species, would you have the macabre stupidity to reject such a remedy, to disdain such a miracle cure? No, that goes without saying. Well this solution does exist, and the mysterious is thereby delivered to us: it consists simply, in its saintly simplicity, to not procreate."
