Meditations 11:10

The natural can never be inferior to the artificial; art imitates nature, not the reverse. In which case, that most highly developed and comprehensive nature—Nature itself—cannot fall short of artifice in its craftsmanship.

Now, all the arts move from lower goals to higher ones.

Won't Nature do the same?

Hence justice. Which is the source of all the other virtues.

For how could we do what justice requires if we are distracted by things that don't matter, if we are naive, gullible, inconstant?
