The article discusses how San Anselmo explained the divine attributes through different names of God in the Proslogion argument. It suggests an identity between the being and truth of God, showing a mutual relationship with Anselm's definition of truth. The fides quaerens intellectum sentence serves as a method for rational clarification of these divine names. The study recognizes a rational limitation in understanding what is believed by faith, following the philosophy of San Agustín. The nominations in the Proslogion and the definition of truth in De Veritate suggest an identity that connects both works of Anselm's thought.
