Daniel Little — Character and authenticity

When we judge that a person has acted on the basis of character in a given situation, we are implying a judgment about his or her inner constitution, and we are judging that the action derived "authentically" from the individual's underlying traits. Character and authenticity go hand in hand. 

So what is "authenticity" when it comes to action? It seems to come down to this. When we talk about authenticity, we are presupposing that a person has a real, though unobservable, inner nature, and we are asserting that he/she acts authentically when actions derive from or reflect that inner nature. This is a kind of moral psychological realism: we work on the assumption that there are real inner features of personality and character that influence (portions of) the individual's behavior.

Is the representative agent rationally pursuing maximum utility acting authentically as a person of character, or does it matter wrt homo economicus? What about human beings as social and political animals?
