Isn't "to know a lot of things" just being wise? Being intelligent, to me, is more about being able to process information, arrive at conclusions - or, in simple words: to think well.

You could be wise without being intelligent (someone who learned a lot by rote learning, but doesn't understand much of it), or vice versa, although the latter is somewhat questionable - an intelligent person will likely use the intelligence to know more and more things. :)

Edit: heck, even D&D had separate wisdom and intelligence stats. :)
