Smith argues that conscience is imagined company: we judge ourselves by picturing an impartial spectator and wanting his approval. The economist famous for self-interest built his moral system on fellow feeling.

Cicero gives the argument to Laelius, a statesman grieving his dead friend: real friendship binds only good men, is wanted for nothing beyond itself, and makes fortune brighter and hardship lighter.

Nothing is good except a good will. From that Kant derives two commands: act only on a principle you could will everyone to follow, and treat persons as ends, never merely as means.

You know you ought to do what you would rather not, and Kant takes that as proof you are free. Freedom, God, and immortality return as what practical reason must assume.

Spinoza proves, in numbered propositions, that God and nature are one substance and that everything follows from it as necessarily as a theorem. Freedom is understanding that necessity, not escaping it.
