On Isaac Asimov’s essay “What is Intelligence, Anyway?”
I think true intelligence has to do with being inquisitive and seeking to learn, and then being able to apply that knowledge creatively, in increasingly sophisticated ways. So it’s not that there’s any one gauge of intelligence, but it’s rather an overall picture of a person’s thirst for knowledge, retention and understanding of it, and ability to apply it.
Knowledge is pointless if you don’t understand it or can’t apply it. Memory or understanding are pointless if you have little knowledge or ability to apply it. And the ability to apply knowledge is pointless if you don’t have any knowledge to begin with, or don’t have the ability to deeply understand it. It’s like a triangle that all works together to make up your ‘intelligence’.
That’s my theory anyway…
