I have one in my pocket here from the first century BCE by Lucretius, the author of "On the Nature of Things," who said, "Tantum religio potuit suadere malorum", I should have been able to learn that by heart — which is, that's how much religion is able to persuade people to do evil, and he was talking about the fact of Agamemnon's decision to place his daughter Iphigenia on an altar of sacrifice in order to preserve the prospects of his army.
Tengo una aquí en mi bolsillo, del siglo I a.n.e., de Lucrecio, el autor de "La naturaleza de las cosas", quien dijo: "Tantum religio potuit suadere malorum" —debí haberlo aprendido de memoria— que se refiere a cuánto la religión puede convencer a la gente de hacer el mal, y nos hablaba de cuando Agamenón decidió llevar a su hija Ifigenia al altar de los sacrificios para asegurar las posibilidades de su ejército.
