"Intelligence" is a hard word to define. At first, when I read your post
@Flavus Aquila, I felt uncomfortable. Why should we put people in such boxes?
Indeed, as you mentioned, people usually call "intelligent" someone who's in fact "cultivated". Knowledge and intelligence are two different things. It's easier to measure the first, though. Intelligence is something extremely confusing. I would personally say it reflects the abilities of a person to adapt to change.
In this thread, the definition you seem to be giving to the concept of "intelligence" is the time someone's brain takes to process information. I don't think that's intelligence, although I see what you mean. Someone who takes long time to process what you're saying, and who can't really reply and add things to the conversation, is not necessarily a person who's lacking intelligence. What I'm trying to say is that some people have amazing capacities of adaptation, but they aren't speakers. It costs them to put their thoughts into words. Therefore, in my opinion, you can't measure the intelligence of people through what they say (or don't say). The cognitive processes of language are just one aspect of what
could be intelligence. Plus, language can be affected by many things, on a psychopathological aspect.
I don't know if what I'm saying makes any sense, ha... because I, myself have difficulties to put my thoughts into words (it's also the case in my native language)
Anyways, I have all kinds of acquaintances. I don't really pay attention to the things you're saying as I consider we all are human beings and therefore, we are all equals. We're all struggling, without rules, trying our best
to be, to live, without having the slightest idea of the reasons why we're here and why we're doing it. That is why every person on this planet deserves respect, whether you call them "intelligent" or not.
