I've always understood the difference between functional programming and imperative programming (maybe some people don't even know that imperative is the term for "not functional") is basically this:

Anyway, describing functional languages by noting some of their "common features" is really not the way to go. It's a philosophical difference, all the way.

(Granted, as you noted, there is a limited concept of "state" in LISP, and, in general side-effect can't be completely avoided or you'd have no means by which to perform I/O... but you're getting into details, there.)
