Reasoning is a robust source of hope and confidence in a world darkened by murky deeds – past and present. It is not hard to see why this is so. Even… - Amartya Sen

"Where is the railway station?" he asks me. "There," I say, pointing at the post office, "and would you please post this letter for me on the way?" "Yes," he says, determined to open the envelope and check whether it contains something valuable.

Even when altruism is allowed (as, for example, in Gary Becker's model of rational allocation), it is assumed that the altruistic actions are undertaken because they promote each person's own interests; there are personal gains to the altruist's own welfare, thanks to sympathy for others. No role is given to any sense of commitment about behaving well or to pursuing some selfless objective. All this leaves out, on the one hand, the evil passions that early theorists of capitalism contrasted with self-interest and, on the other, the social commitments that Kant analyzed in The Critique of Practical Reason and that Adam Smith discussed in The Theory of Moral Sentiments.

The global reach of Smith's moral and political reasoning is quite a distinctive feature of his thought, but it is strongly supplemented by his belief that all human beings are born with similar potential and, most importantly for policymaking, that the inequalities in the world reflect socially generated, rather than natural, disparities.
There is a vision here that has a remarkably current ring. The continuing global relevance of Smith's ideas is quite astonishing, and it is a tribute to the power of his mind that this global vision is so forcefully presented by someone who, a quarter of a millennium ago, lived most of his life in considerable seclusion in a tiny coastal Scottish town. Smith's analyses and explorations are of critical importance for any society in the world in which issues of morals, politics and economics receive attention. The Theory of Moral Sentiments is a global manifesto of profound significance to the interdependent world in which we live.
