I agree with most of the commentaries about their principles. They are sound and common-sense. My basic principle is what is called "The Rule of Gold". I don't do to the others what I don't want the others to do to me. It is very generic, but it applies to almost all human interactions.
I have heard that referred to as the Silver Rule. Contrasted with the Golden Rule (as I learned it) "Do unto others as you would have them do unto you".
The rule you described (whatever it is called) is better in my opinion.
