Reason is Unprincipled

Often one catches word, that someone is trying to be too rationale, and therefore rigid. Usually this means something else, for example that someone was being rigid about a premise ... or a principle ... but reason is inherently unprincipled.

The word "reason" comes from "ratio", hence the synonimity of being reasonable and being rationale. Less commonly acknowledged is the Eastern equivalent, which is to be moderate. And moderation in all things is by definition, to waiver on all things, including principals.

So our common language captures much irony.
