Smith, Friedman, and Self-Interest in Ethical Society

We examine the writings of Adam Smith and Milton Friedman regarding their interpretation and use of the concept of self-interest. We argue that neither Smith nor Friedman considers self-interest to be synonymous with selfishness and thus devoid of ethical considerations. Rather, for both writers self-interest embodies an other-regarding aspect that requires individuals to moderate their actions when others are adversely affected. The overriding virtue for Smith in governing individual actions is justice; for Friedman it is non-coercion.
