Intellectual Lee?

What does that term 'intellectual' mean anyway..? Recently I got into an argument with Ms W. about the term because she told me that I, Rodney Lee, am not intellectual. Hmm. At first I was like, "you're right, i'm not..." But at that point what I meant is that I'm not an academic... But I don't think we quite agreed about what makes a person an intellectual. So, I'm curious what other people think: what qualifies a person as an intellectual? I mean, I have always considered myself an intelligent person, but what does it mean to be an intellectual? Is their a distinction between being intelligent and being an intellectual? If so, what would be the distinction? And if they are the same, what does the word mean anyway....?
