I got the 10th anniversary edition, which includes a new introduction. I was only a few pages in when I came across this bit:
Those interested in the evolution of the theory of multiple intelligences since 1983 often ask whether additional intelligences have been added--or original candidates deleted. The answer is that I have elected not to tamper for now with the original list, though I continue to think that some form of "spiritual intelligence" may well exist.
Ack. Spiritual intelligence?
His theory outlines the following intelligences:
- linguistic intelligence
- musical intelligence
- logical-mathematical intelligence
- spatial intelligence
- bodily-kinesthetic intelligence
- personal intelligences
Here's the Wikipedia article on spiritual intelligence. I'll leave it to you to decide whether you think it's hogwash.
