One glaring presupposition (which is false) of "rationalist approaches", but also those who reject them, yet maintain the same inherently hyper-individualistic, atomistic conception of human beings[0], is immediately apparent in the first sentence of the abstract: "Rationalist approaches to economics assume that people value their own interests over the interests of strangers."<p>It is NOT in my interest to be dishonest. To think it is is to fail to understand that human nature is <i>thoroughly social</i> and that, because of that, there is a common good. The common good is prior to private good; the latter depends on the former, not the other way around, as liberal philosophy conceives it.<p>Thus, maximizing my own interest, by which I mean my own good, is to live maximally in conformity with human nature, and part of that means living in a way that recognizes the primacy of the common good. Dishonesty <i>per se</i> is also harmful to the individual in the <i>very act</i> of being dishonest. A person is corrupted in the <i>very act</i> of being dishonest.<p>[0] I am <i>not</i> denying the existence or worth of individuals. I reject collectivism which is ready to throw the individual under the bus for the collective (which is rather incoherent). I mean only the conception of human beings as <i>atomic</i>, in which society is merely transactional or contractual, instead od recognizing transactions as a subset of actions that occur within a social context and only where transactions are appropriate and make sense).
