This book is a real treasure to those dedicated to the human-historical studies. It's a well-thought, well structured critical analysis and comparative study on the idea of human existence in historical time - in other words, "historicality of human nature" - as seen and developed by the three thinkers. Really easy and joyful reading, supported by an accurate endnotes and quite an impressive bibliography, that covers sources in English, German, Spanish, and French.

Charles R. Bambach has done us a kindness by providing us with this detailed, ambitious, and thoroughly readable treasure of scholarship. He demonstrates, above all, the kind of scholarly precision and erudition that is sorely lacking in most books on Heidegger. This book is a must read for anyone interested in 19th and 20th century philosophy of history. It is far superior to its only comparable predecessor, Jeffrey A. Barash's "Heidegger and the Problem of Historical Meaning."

The only negative thing I have to say about this book is that the thread of the argument is inscrutable at times. The overall point, of course, is quite clear, but one tends to become lost in the details. The last chapter on Heidegger is particularly flawed in this respect.

All the same, this book is a new departure in Heidegger scholarship, and ought to be well-received by all.
