Sometimes we forge our own principles and sometimes we accept others' principles, or holistic packages of principles, such as religion and legal systems. While it isn't necessarily a bad thing to use others' principles - it's difficult to come up with your own, and often much wisdom has gone into those already created - adopting pre-packaged principles without much thought exposes you to the risk of inconsistency with your true values.
