By omitting the adjective vetus in the French translation of the sentence “...infixa quaedam est meae menti vetus opinio...” in the first of the Meditationes de prima philosophia, the reader finds himself without an epithet that clearly refers to the idea of divine omnipotence and to the distinction between absolute power and ordered power in William of Ockham and other post-scotists. What is at stake in the debate over the opinion invoked is the question concerning the relation between the divine deceiver and the doctrine of the creation of eternal truths.
