Vi veri universum vivus vici

“Vi veri universum vivus vici” portrays the true triumph of good over evil.
In Goethe’s tragedy, the renowned alchemist Doctor Faustus is considered one of God’s favored souls. Because of this, he becomes desired by the Devil. In an agreement between good and evil, the Evil One offers to fulfill Faustus’s desires and reveal to him the true meaning of life and happiness, in exchange for his eternal servitude — his soul.
Faustus, a notoriously clever and perceptive man, accepts the proposal, but only on one condition: that, by the end of his life, he must be able to say he experienced one single, genuine moment of happiness.
As the story unfolds, and despite the Devil’s many attempts, Doctor Faustus never truly reaches that state of absolute happiness. In a final act of repentance, he is advised by a priest to speak the truth until his very last moments, so that the pact he made may be broken. He does exactly that, and upon his death, Faustus is accepted into Heaven by God.
The Devil, outraged, questions the Father of all things. God then tells him that truth is powerful enough to free even the most impure souls.
“Vi veri universum vivus vici” means:
“By the power of truth, I, while living, conquered the universe.”
Another accepted translation is:
“By the force of truth, I, a mortal, conquered all creation.”
