There are relatively few philosophers capable of producing a book like this one. Trust represents the work of a seasoned philosopher who has spent a lot of time thinking through the perennial and fundamental questions that persons interested in the pursuit of genuine wisdom must ask. It is a book that shows remarkable coherence, brevity, and depth. - Norman Wirzba, Duke Divinity School By these particular studies of trust as related to society, nature and self, the author leads the reader to a conclusive and original study of trust in philosophy (existential wisdom) as distinct from Cartesian doubt to undergird scientia and to retrieve the traditional philosophical understanding of the centrality of trust for producing philosophy as sapientia (existential wisdom). - David Tracy, University of Chicago
