After the passions pass, Justice remains to put things back in order and help us regain perspective. In addition to this social function, Justice provides a personal function as well. The person who has been captured by an amorous or martial form of idealism will not easily return to a life of unexamined habits. Justice is an ideal that can sustain and inspire one's moral life even after social and religious conventions have been cast into doubt. Each synthesis is also a transcendence.
Justice operates as third intervening deity, helping to clean up after the others.
In doing so, she suggests the possibility of actually achieving a position of mastery over them.
