While the performance was quite good, Menand's text is what really makes this book worth listening to.
To be honest, to get the most out of this book, the reader probably needs some knowledge of the American Civil War. It would also help to know a bit about early American philosophy and psychology. However, if the reader remains patient, Menand eventually fills in the missing details.
Overall, the Metaphysical Club is a very well written and complex history of a fascinating group of thinkers.
