Knowledge doesn't bring life to the good. Others say discipline is the key. Yet people closest to us know what kind of people we really are. Through discipline we might create a world in our minds, but we still live in this world. All too often exercise seems ineffective in bringing life to the good.
Religion is another option.
Perhaps if we go to church, a mosque, or a synagogue, or if adopt a new religious perspective, then we will become better people. Unfortunately, what we usually gain from religion is another outlook on the world that will grow old, not the start of a new life within us. Finally, some say, the law is the best choice for attaining good. If we have legislation that can regulate our behavior, particularly our moral behavior, then we will be better citizens and people. Yet more rules lead to oppression rather than to a desire to do right.
