"What can be added to the happiness of a man who is in health, out of debt, and has a clear conscience?"

Adam Smith's quote speaks with the idea that true happiness is found in the easy things in life. He suggests that an individual who is in health, free from financial obligation, and has a peace of mind is currently in a state of contentment and happiness. This suggests that product possessions and wealth are not needed for true happiness. Rather, Smith suggests that the most essential parts of happiness are physical and mental wellbeing, financial security, and a sense of morality. He indicates that if a person has these three things, then nothing else can be contributed to their happiness. This quote works as a reminder that true joy is found in the simple things in life, which product ownerships are not needed for satisfaction.
