Vanini certainly made one of the speakers in the Dialogues prove (_De naturæ arcanis_, p. 420) even “out of the text of the Bible, that the devil is mightier than God,” and that therefore God does not rule the world. Among his arguments are the following: It was against the will of God that Adam and Eve sinned, and thus brought the whole human race to ruin (_ad interitum_): Christ also was crucified by the powers of darkness. Moreover it is the will of God that all men should be saved. But of Catholics there are very few in comparison with the rest of the world, and the Jews often fell away from their faith; the Catholic religion extends only over Spain, France, Italy, Poland and a part of Germany. If there were to be deducted also the atheists, blasphemers, heretics, whoremongers, adulterers, and so on, there would be still fewer left. Consequently the devil is mightier than God. These are arguments of reason; they are not to be refuted; but he submitted himself to the faith. It is remarkable that no one believed this of him; the reason thereof being that it was impossible for him to be in earnest with the refutation of what he asserted to be rational. That the refutation was but weak and subjective does not justify anyone in doubting Vanini’s sincerity; for poor reasons may be convincing for the subject, just as the subject holds to his own rights in respect of objective matters. What lies at the bottom of the proceedings against Vanini is this, that when a man by means of his reason has come to perceive something which seems to him incontrovertible, he cannot but adhere to these definite perceptions, he cannot believe what is opposed to them. It is impossible to believe that faith is stronger in him than this power of perception. The Church in this way fell into the strange contradiction of condemning Vanini, because he did not find her doctrines in accordance with reason, and yet submitted himself to them; she thus appeared to demand—a demand which she emphasized with the burning pile—not that her doctrines should be considered above reason, but in accordance with it, and that reason should have merely the formal function of explaining the content of theology, without adding anything of her own. This susceptibility of the Church is inconsistent, and entangled her in contradictions. For in earlier times she certainly admitted that reason could not grasp what was revealed, and that it was consequently a matter of little importance to refute and solve by reason the objections which reason itself brought forward. But as she now would not permit the contradiction of faith and reason to be taken seriously, but burned Vanini at the stake as an atheist for professing so to do, it was implied that the doctrine of the Church cannot contradict reason, while man has yet to submit reason to the Church.
