I need to add that my work on multiple intelligences received a huge boost in 1995 when Daniel Goleman published his book on emotional intelligence. I am often confused with Dan. Initially, though Dan and I are longtime friends, this confusion irritated me.

Emile Zola was a poor student at his school at Aix. We are all so different largely because we all have different combinations of intelligences. If we recognize this, I think we will have at least a better chance of dealing appropriately with many problems that we face in the world.

In the United States, if you ask teachers, "Are there children whom we should call 'gifted?'", many if not most will say 'No.' That's the politically correct answer. But if you then ask the teacher to rank order students in terms of how well they paint or write or dance, they'll have little difficulty in doing so.

Now intelligence seemed quantifiable. You could measure someone's actual or potential height, and now, it seemed, you could also measure someone's actual or potential intelligence. We had one dimension of mental ability along which we could array everyone... The whole concept has to be challenged; in fact, it has to be replaced.

If you think education is expensive, try estimating the cost of ignorance.

Distinguish between the work and the job title. When I was leaving school in the early 1970s, many people wanted to be journalists, carrying out investigative reporting for print newspapers. Print newspapers may not exist in twenty years. But good thinking and good writing about issues that need to be reported and investigated will always be needed; but where this happens, what it is called, and who pays for it may be quite different than could have been envisioned by the great journalists of the past.

Hitler didn't travel. Stalin didn't travel. Saddam Hussein never traveled. They didn't want to have their orthodoxy challenged.
