The soul is perfected by knowledge and virtue.
The celestial bodies are the cause of all that takes place in the sublunar world.
Faith does not quench desire, but inflames it.
There is nothing on this earth more to be prized than true friendship.
That the saints may enjoy their beatitude and the grace of God more abundantly they are permitted to see the punishment of the damned in hell.
To one who has faith, no explanation is necessary. To one without faith, no explanation is possible.
