88 Saint Augustine expounds this teaching in detail in his dialogue on free will (De libero arbitrio, II, 3, 8ff.). He indicates the existence within the human soul of an "internal sense". This sense consists in an act that is fulfilled outside the normal functions of reason, an act that is not the result of reflection, but is almost instinctive, through which reason, realizing its transient and fallible nature, admits the existence of something eternal, higher than itself, something absolutely true and certain. The name that Saint Augustine gives to this interior truth is at times the name of God (Confessions X, 24, 35; XII, 25, 35; De libero arbitrio II, 3, 8), more often that of Christ (De magistro 11:38; Confessions VII, 18, 24; XI, 2, 4).
