Pinker argues clearly and passionately that rationality and reason are vital and that their current abandonment by a worrying number of people is dangerous. He looks at the role of rationality and the essential part it plays in maintaining a civilised society and also attempts to analyse why some people reject it in favour of irrationality, conspiracy theories, evidence-free fantasies and so on. This includes some good analysis of why scientific data can be messy and a clear explanation o why that doesn’t mean that it can simply be ignored.
All of this is commendable but I had some reservations. Firstly, although Pinker has a reputation for brilliant, readable writing, I found the prose quite hard going in places. It is dense, unalleviated by much in the way of light relief and burdened by his tendency to use obscure words where ordinary ones will do just as well – “patrimony,” for example where “inheritance” would make at least as much sense and make for a far easier read.
Secondly, I wasn’t really sure that Pinker was saying much that was new. The book, he explains, grew out of a course he taught and that makes it, for me, a restatement of pretty well rehearsed arguments and ideas. Important, certainly, and a useful restatement of arguments but not all that stimulating.
And thirdly, I kept getting a strong feeling that he is preaching to the converted. This is a book aimed at and surely read by those who, like me, already believe strongly in rationality. It may strengthen our stance, but will it change what really needs to be changed?
I don’t want to be too harsh; this is a good, important book. However, for me Robin Ince’s recent, very enjoyable and equally important book The Importance Of Being Interested said much the same thing in a far more readable and witty way, which may do a better job of reaching the people it needs to.
