The paper deals with the intervention of rational explications in the theological discussions in Early Scholasticism (inspired by some of the scholars around 1000, among them Gerbert of Aurillac or Fulbert of Chartres). The main aim is to shed light on the interpretation of God's omnipotence by Peter Damiani (in his famous open letter' De divina omnipotentia') and Anselm of Canterbury (especially in his works 'Proslogion', 'De libero arbitrio' and 'Cur Deus homo?') and to show how: Aristotle, Hieronymus, Augustine and Boethius influenced their way of thinking.
