Practical wisdom allows us to make decisions that improve our eudaimonia, the (ethically) good life. Courage can be physical, but more broadly refers to the moral aspect—for instance, the ability to act well under challenging circumstances, as Priscus and Malala did. Temperance makes it possible for us to control our desires and actions so that we don’t yield to excesses. Justice, for Socrates and the Stoics, refers not to an abstract theory of how society should be run, but rather to the practice of treating other human beings with dignity and fairness.
