This is a story of two men: one is blind but has “vision”, to study the biology of bees; the other has sight, his manservant/assistant. The context is fascinating, an estate outside Geneva in the 1780-90s. So, like Darwin, the book describes painstaking research undertaken by amateurs. Experiments proceed by careful observation, by trial-and-error, but there is no documentation of course. Their bee research has another context, the French Revolution. This is a very fine book.
