What we want: honesty and integrety

From William Brown's Character in Crisis: A Fresh Approach to the Wisdom Literature of the Old Testament.

"In other words, moral virtues tend to cut across all situations of conduct, from professional to personal.  To compartmentalize the virtue of honesty by relegating it to, for example, one's personal life but excluding it from one's professional conduct, is no virtue.  Virtues are by nature all encompassing."

This is at the heart of why we care about public officials obeying the tax laws and not engaging is illicit relationships; because trustworthiness, or un-trustworthiness, is not contained in a single arena of life. That said, a mixed anthropology that recognizes that human beings are not purely virtuous also must evaluate the effect of flaws in one arena upon the whole.  One error may not be an indication that the whole is damaged beyond suitability for service.  Seldom will there be a public official or private person whose behavior in every situation is beyond reproach so we must exercise judgment about our contemporaries (including ourselves) and about historical figures.  Perhaps this is somewhat less difficult in retrospect since we can attempt to see the overall pattern and the consequences, but in the present we can not take into account what is still to come.
