An ad hominem from the philosopher? On Christmas Eve? The horror!
Not that C. needs any help, but the social psychological research on this is clear: changes in behavior and social conditions lead to changes in attitudes and beliefs. It is not that people consistently act on the basis of their well developed beliefs (moral or otherwise); rather, people act and then shift their beliefs as needed to justify their actions.
I know this directly challenges our culturally embedded notion of personhood; we assume that moral behavior is simply a psychological product of the "proper" belief system. Why this assumption? The common sense notion of the autonomous agent is an ideological precipitate of capitalist social relations. The free market literally creates people who must rationally calculate and choose among commodities, investments, and jobs. Without the incessant valorization via capitalist social relations, would the notion of the rational, self-determining agent persist? I wonder.
Cheers,
