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

Question

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.

Answer 1

Depending on where you use it, but if you look at famous usages they are translated into as:

• Archimedes' principle　 アルキメデスの原理
• The uncertainty principle　 不確定性原理
• The Monroe Doctorine 　モンロー主義
• Philosophy of science　 科学哲学
• the Pythagorean theorem　 ピタゴラスの定理 or 三平方{さんへいほう}の定理
• Theory_of_relativity 　相対性理論
