Rethink is a look at the history of ideas. How there are very few truly new ideas, but a lot of ideas which were thought up before they reached their time. The focus was spread across scientific, political and economic disciplines, leaping from astronomy to mental health via chess.
The encouragement is to look again at currently discredited ideas, and to be patient with new ideas that require time and understanding be accepted as conventional. It makes fascinating reading, as links to modern ideas are found in ancient texts, and I enjoy a good story on an old academic debate, where what we know as a fundamental truth was first proposed.
Then there is a look at what ideas could be due for renaissance. This is where we steer quite firmly into political and economic territory, betraying Poole’s lack of scientific training. But these are all ideas which are moving into the Overton window, and becoming feasible in a way that they weren’t 20 years ago.
An interesting look on how ideas develop and move in and out of being accepted truths in human society.
