Another way to see the point Socrates gave his life to make is to look at society today. How much of our suffering comes from people (including ourselves) who do not examine our own beliefs and behaviors? If everyone examined his or her own feelings and gained self-mastery, living passionately but lovingly, without causing harm, would we have war? Would there be any poverty? Would there be much less illness?
Collectively, our unexamined lives create the ills of society. Socrates taught us to examine our lives and our minds and our hearts, and so create a society of excellence, a society diligently focused on creating the Good. Each individual who does this enhances the life of the world.
