The position of welfare economics in modern economic theory has been a rather precarious one. In classical political economy there were no sharp boundaries drawn between welfare economic analysis and other types of economic investigation. But as the suspicion of the use of ethics in economics has grown, welfare economics has appeared to be increasingly dubious, It has been put into an arbitrarily narrow box, separated from the rest of economics.

The methodological strategy of using the concept of rationality as an 'intermediary' is particularly inappropriate in arriving at the proposition that actual behaviour must be self-interest maximizing. Indeed, it may not be quite as absurd to argue that people always actually do maximize their self-interest, as it is to argue that rationality must invariably demand maximization of self-interest. Universal selfishness as actuality may well be false, but universal selfishness as a requirement of rationality is patently absurd.

Since the conception of human rights transcends local legislation and the citizenship of the person affected, it is not surprising that support for human rights can also come from anyone—whether or not she is a citizen of the same country as the person whose rights are threatened. A foreigner does not need the permission of a repressive government to try to help a person whose liberties are being violated. Indeed, in so far as human rights are seen as rights that any person has as a human being and not as a citizen of any particular country, the reach of the corresponding duties can also include any human being, irrespective of citizenship.

I personally have great skepticism about the theories extolling the wonders of "Asian values." They are often based on badly researched generalizations and frequently uttered by governmental spokesmen countering accusations of authoritarianism and violations of human rights (as happened spectacularly at the in Vienna in 1993).

The behavioral foundations of capitalism do, of course, continue to engage attention, and the pursuit of self-interest still occupies a central position in theories about the workings and successes of capitalism. But in these recent theories, interests are given a rather different—and much more "positive"—role in promoting efficient allocation of resources through informational economy as well as the smooth working of incentives, rather than the negative role of blocking harmful passions.

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 Passions and the Interests does not have the policy urgency that a contribution to public decisions may enjoy (as Hirschman's The Strategy of Economic Development eminently does), nor the compulsive immediacy that the exigencies of practical reason generate (as Exit, Voice, and Loyalty superbly portrayed). What then is so special about this book? […] The answer lies not only in the recognition that Hirschman makes us see the ideological foundations of capitalism in a fresh way, but also in the remarkable fact that this freshness is derived from ideas that are more than two-hundred-years old. The basic hypothesis— the articulation and development of which Hirschman investigates—makes the case for capitalism rest on the belief that "it would activate some benign human proclivities at the expense of some malignant ones."

"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.
