But architectural aesthetics aren't a quantitative field of study, so it's obvious from the get-go that we're not dealing with the same kinds of facts as in the natural sciences. From there, it's fairly obvious that these terms describe
principles, not authoritative laws of nature.
It's quite strange to get hung up on this issue. Yes, those principles are subject to interpretation/taste/subjectivit/etc, but that's hardly the point.
I mean no disrespect to anyone in this comment thread, but this line of criticism is pedantic.
