Keep the ethics worth keeping, and scrap the rest.
God and the State (1871)
Mikhail BakuninThe Bible, which is a very interesting and here and there very profound book when considered as one of the oldest surviving manifestations of human wisdom and fancy, expresses this truth very naively in its myth of original sin. Jehovah, who of all the good gods adored by men was certainly the most jealous, the most vain, the most ferocious, the most unjust, the most bloodthirsty, the most despotic, and the most hostile to human dignity and liberty - Jehovah had just created Adam and Eve, to satisfy we know not what caprice; no doubt to while away his time, which must weigh heavy on his hands in his eternal egoistic solitude, or that he might have some new slaves. He generously placed at their disposal the whole earth, with all its fruits and animals, and set but a single limit to this complete enjoyment. He expressly forbade them from touching the fruit of the tree of knowledge. He wished, therefore, that man, destitute of all understanding of himself, should remain an eternal beast, ever on all-fours before the eternal God, his creator and his master. But here steps in Satan, the eternal rebel, the first freethinker and the emancipator of worlds. He makes man ashamed of his bestial ignorance and obedience; he emancipates him, stamps upon his brow the seal of liberty and humanity, in urging him to disobey and eat of the fruit of knowledge.
We know what followed. The good God, whose foresight, which is one of the divine faculties, should have warned him of what would happen, flew into a terrible and ridiculous rage; he cursed Satan, man, and the world created by himself, striking himself so to speak in his own creation, as children do when they get angry; and, not content with smiting our ancestors themselves, he cursed them in all the generations to come, innocent of the crime committed by their forefathers. Our Catholic and Protestant theologians look upon that as very profound and very just, precisely because it is monstrously iniquitous and absurd. Then, remembering that he was not only a God of vengeance and wrath, but also a God of love, after having tormented the existence of a few milliards of poor human beings and condemned them to an eternal hell, he took pity on the rest, and, to save them and reconcile his eternal and divine love with his eternal and divine anger, always greedy for victims and blood, he sent into the world, as an expiatory victim, his only son, that he might be killed by men. That is called the mystery of the Redemption, the basis of all the Christian religions. Still, if the divine Savior had saved the human world! But no; in the paradise promised by Christ, as we know, such being the formal announcement, the elect will number very few. The rest, the immense majority of the generations present and to come, will burn eternally in hell. In the meantime, to console us, God, ever just, ever good, hands over the earth to the government of the Napoleon Thirds, of the William Firsts, of the Ferdinands of Austria, and of the Alexanders of all the Russias.
Such are the absurd tales that are told and the monstrous doctrines that are taught, in the full light of the nineteenth century, in all the public schools of Europe, at the express command of the government. They call this civilizing the people! Is it not plain that all these governments are systematic poisoners, interested stupefies of the masses?
