"Is there a difference between a man who thinks honesty is the best policy and an honest man?"
- C. S. Lewis
Sure, an honest man is honest by habit and not by cost-benefit calculation.
"It is, thus, always important to keep in mind that professional [personal] ethics depends mainly on constant vigilance, on sustained discretion and prudence, and on wisdom, rather than on certain set rules. It is true here as elsewhere that character is destiny."
Belle And Sebastian - Piazza, New York Catcher
