Both Muller and Walker talk about authenticity in an almost moral sense. [fact]
The well-read Muller chooses not to reveal deeply personal things, but believes strongly in the ideal that "principles within our hearts," personal integrity, should dictate one's actions, rather than marketing principles. Both Muller and Walker talk about authenticity in an almost moral sense, adhering to consistency as a driving ethic. This sense of authenticity suggests that it is not about how much one reveals or conceals, but about being measured against an ideal of honesty, in that the information that is revealed has a constancy.
