Different kinds of ethical structure
A command tells a person what must or must not be done. A precept may be voluntarily undertaken as training. A vow is a commitment. A virtue describes a quality of character. A path combines conduct, understanding and practice over time.
What comparison can and cannot show
Comparison can identify shared concerns such as killing, deception, property, generosity and self-control. It cannot establish that two similarly worded principles have the same source, authority, intended audience or practical meaning.
Truth By Reason method
Each record separates primary wording, translation, traditional interpretation, historical development and independent ethical analysis. Religious authority is described rather than assumed.
