What?
You can't just disassemble 熟語 in that fashion. 原理 is a word that contextualizes that Kanji that compose it. Drawing a link between 原理 (an ordinary word) and 人理 (a made-up word) seems farfetched, at best. Not to mention that the fashion 原理 is used within the text seems to suggest nothing of the sort you are implying.
