I am all for education, since it delivers knowledge, which I highly value. However, knowledge is discrete and not universal, so an "educated" person could be deficient in many things. Intelligence is widely diffused and can be found anywhere. So can stupidity. The life test is: Can you tell the difference when you meet and speak to someone? I guess that is the test of intelligence, right there. Your own intelligence. Read, listen and learn without ceasing. That should do it for you.
