It’s much more fashionable to attack Adam Smith these days than to read him. Yes, he favored economic liberalism, which wasn’t exactly in style in his time. Nor is it in ours. History remembers him as cold and calculating. But in real life, he was neither.
There are two main drivers behind Smithian liberalism, neither of them cold or calculating. One is that man is a social animal. The foundation of Smith’s moral theory is the impartial spectator theory. People figure out the right thing to do by asking themselves if an impartial third party would approve of their actions. Empathy — thinking of others and feeling for them — is at the very heart of Smithian morality.
Take trade, for example. Smith is well known for being an ardent free trader. But why? Because trade is an inherently peaceful act.It is moral.
If you have something I want, I’m not going to hit you over the head and steal it. No impartial spectator would approve of that. Instead, I’ll trade it to you for something you value even more. Everyone wins.
If you don’t think you’ll gain from the exchange, then nobody can force you to make it. And no one will trade with you unless you treat them with civility and dignity. Trade is much more moral than the alternative.
