I have read all of Shakespeare's plays, plus all the novels of Dickens, Jane Austen and Virginia Woolf. Right now, I am halfway through Middlemarch, and I'm also wading through Proust, partly in French, partly in English.
But, am I intelligent? No, I wouldn't say so. For a start, I'm utterly hopeless at anything even vaguely mathematical. As for technology, don't get me started. Most 10-year-olds know more than I do. I've often handed a phone or laptop to somebody, with tears of rage in my eyes, to stop me throwing it through a window. And though science interests me, I really struggle, and quickly forget everything I've read. Also, no matter how many books I read on grammar and punctuation, none of it sticks, and to this day I'm unsure where to place my commas.
More generally, I can't follow instructions, have no sense of direction, and often struggle to learn new things. Verbally I'm pretty good, however. I'd say I'm eloquent (I can speak without pausing, or saying 'er' or 'y'know', etc). I'm also fairly witty/quick-witted, and a pretty good conversationalist. It's a lopsided intelligence. On an IQ test, I suspect I'd score quite high in some areas, but well below average in others.
The one subject at which I excelled was literature. I could hold my own against most people in a discussion about, say, Wuthering Heights, or Pride and Prejudice. Yet even with literature I know my limits. For example, I once sat through a university seminar on T. S. Eliot, taken by a young PhD student. The guy was only about 22, yet his knowledge and insight, his grasp of poetry, left me standing. He was in a totally different league.
