On the origin of divisional tongues...

Just something I started wondering about... does anybody know what inspired the introduction of divisional tongues? E.g. languages for the various alignment factions? The concept of a language of "Law" versus a language of "Neutrality" versus a language of "Chaos" in that strict division seems somewhat strange to me. It kind of implies an overarching religious or metaphysical concept, even stronger than in the books of Michael Moorcock (I don't remember seeing any aligned tongues in those books) which seems rather strange for a game that otherwise has almost no hints about the way religions might work.

So, any takers for literary examples that might have influenced the original rules in presenting such a strange special case?

One thing that bewilders me while reading the little brown books is the comparative detail given to languages - at least when comparing the language section to other parts of the rules.
