How do you say things like "The ________ Principle" in Japanese?


What are Japanese equivalents to saying that something is a principle,
doctrine, or philosophy? You know, things that would be phrased as something
like "The ________ Principle/Doctrine", or "The Philosophy of ________" in
English?

I've found a couple of ways, using words like 法、理、原理、原則、義、etc. but I'm not
sure which to use or how to use it as to form normal-sounding phrases with the
proper nuance.
