“To illustrate the important differences between rules and principles, how do you react to the following statement? Thou shall not kill. If you are like most people, your mind is probably thinking of a number of exceptions: What about in the time of war, or in self-defense? What if, on the other hand, I said, Love one another. Now where does your mind go? You’re caught, aren’t you? There is no exception to be found. Thou shall not kill is a rule; Love one another is a principle. A rule merely requires compliance, whereas a principle requires discernment, the ability to judge wisely and objectively. If you want to define a higher standard of care based on trust, you must do so with principles, not rules.”
