Boundaries

The title of this book takes the adage about ‘thinking outside the box’ and inverts it. Instead of thinking outside the box, we should think inside the box, David Epstein argues. Which box? How big is this box? Whose box? He discusses these questions as well. The phrase ‘thinking outside the box’ emerges from the nine dots puzzle devised by psychologists before the first world war. There are nine dots on a page, evenly spaced, three on each line. You must connect all nine using four lines without removing your pen from the paper. A common response is to imagine that the dots form a box and to confine your work accordingly. This makes the puzzle impossible to solve; you have to think outside the box. Or not think of a box in the first place.

This is a treasure house of a book, filled with curiosities and evidence of a rare breadth of patient investigation. Anyone who has read one of Graham Robb’s books, from his early biographies of classic French writers, through a wonderfully amusing study of 19th-century homosexuals, to a series of historical and geographical studies of France and Britain, will not be surprised at that. What is new in this idiosyncratic history of the British Isles is Robb shifting some of his own encounters to the foreground. In previous books, the experience of bicycling has been fruitfully used.
