The Three Parts of Morality

Lewis challenges the common misconception that morality is merely a set of rules that restricts enjoyment. Instead, he argues that moral rules are akin to instructions for operating a machine, designed to prevent breakdowns and ensure smooth functioning. He uses the analogy of a fleet of ships to illustrate that morality involves three key aspects: fair play and harmony between individuals, internal harmony within each individual, and the overarching purpose or direction of human life. Lewis emphasizes that focusing solely on social relations without addressing internal morality and the ultimate purpose of life is insufficient. True morality requires attention to all three dimensions.
