Paul Ricoeur is a philosophical and theological thinker whose scope and economy of writing is unmatched in this age. Still more, it is difficult to find philosophers and theologians who can adequately engage with him. That the author, Richard Kearney, was a former student of Ricoeur's still makes no guarantee that he can do so. But Kearney does, indeed.
Kearney's book is first class in this field of thinking on Ricoeur. I would consider it as important as any of Ricoeur's own books. Though it is not "critical", this books lays out a wonderful exposition of many of Ricoeur's points. In this sense, it is better than a critical approach which often puts the progect of critiquing before understanding what is being read or thought.
