The concept of multiple intelligences is blindingly obvious to the layman; what is less obvious is whether we should take the author's opinion seriously. The author assembles his list of the most important human abilities/intelligences. He then waffles on endlessly about his euphoric pleasure of experiencing people who display these skills. No argument or evidence is given to support this list. He describes an `intelligence', as the ability to solve problems. The dictionary I consulted, described it as understanding/speed of understanding. When I looked online, I got another range of opinions as to its meaning. In other words, the book is about a subject with no accepted definition.
According to the author, poetry, ballet, an extensive vocabulary and the ability to write classical music, is the pinnacle of human intelligence. It should be remembered that whatever these mental abilities/intelligences are, they were developed 10,000 years ago to allow humans to survive. The author does not explain how poetry, literary ability and music allowed humans to survive.
What this author has done is to take all the human qualities and abilities, valued by upper-class intellectual elite, of civilised societies and classified them as the most important human intelligences. This is precisely what IQ testing is accused of at the start of this book. We are expected to accept all this purely because the author's says-so.
