A collection of short essays about the next “dangerous idea”. Copernicus’s idea that the earth went round the moon and Darwin’s idea of evolution are given as the stock examples of ideas that were dangerous in the past. What will be proved true in the future that we would find difficult to believe today?

I found the articles to be very hit and miss. They variously seemed too obvious, too esoteric or barely worth mentioning. And too many were of the navel gazing “the idea of a dangerous idea is dangerous” or variations. One of the problems is that there are a lot of short articles and they’ve been arranged so that the themes follow on from one writer to the next; this makes for some degree of redundancy. There is a lot here that’s interesting to read but the book as a whole wasn’t gripping.
