One might suppose that people live badly only because their thoughts are disordered. Just fix their thinking and they’ll be all right.
That is only half the problem. People also think badly because their lives are disordered. There are certain things it is impossible to find plausible unless one is at war with all the obviously true things one dare not allow oneself to believe.
Perhaps this is another reason why Aristotle thought it was pointless to try to teach ethics to people who had not been well brought up. Apparently he had the cozy luxury of choice. Those who do not must find another way.
