Explain Lewis’s three-part account of morality and why he thinks social rules alone are insufficient.
Answer
A strong answer should identify fair relations between people, the ordering of each person’s inner life, and humanity’s relation to the purpose or power behind human life. Social rules matter, but they cannot work reliably if individuals remain greedy, cowardly, or self-centred. Lewis also argues that beliefs about humanity’s purpose affect which moral duties people recognize.
Explanation
### Why this is right
Lewis’s three-part model shows why morality cannot be reduced to social harmony. A society needs fair relations, but those relations depend on people whose own desires and characters are ordered and who understand what human life is for.
### The concept
Lewis compares morality to a fleet: ships must avoid colliding, each ship must be seaworthy, and the fleet must be going to the right destination. These correspond to relations among people, inner character, and the overall purpose of human life. Rules or institutions alone cannot make a society good if individuals find ways to pursue selfish ends through them.
### What a good answer covers
- The three departments of morality.
- The fleet analogy and what each part represents.
- Why individual character and beliefs about purpose matter alongside social arrangements.
### Remember
A good moral system needs fair relations, well-ordered people, and a sound destination.
