An exceptional work of scholarship that will open a vast new conception of the history of ideas to the non-philosophers that this accessible book is designed to reach. Paul Heitsch’s performance is spirited too. However, Heitsch mispronounces key names throughout the book: the name Peirce is supposed to be pronounced like ‘purse’; not like ‘pierce’, as Heitsch does. Dilthey is supposed to be pronounced ‘Dil-tie’, not ‘dil-thee’. Considering he is a protagonist of this account, it is mind-numbing to hear the intellectual giant Peirce’s name mispronounced over and over again. You people had one job.
