Those who have successfully progressed in their therapeutic path have attained Justice. Those who have not, have attained Injustice. Those who have attained Justice have practiced a soul's therapy that can be defined as "human" and that led them to earthly happiness. They used as their therapy the "medicina animi", the "soul's medicine" provided by the cardinal virtues (in the sequence Prudence-Fortitude-Temperance-Justice), namely the moral and intellectual virtues with whose "medicine" human beings can be cured of, and are able to prevail over, the opposing vices.
