Pragmatist philosopher William James has long been deemed a dubious guide to ethical reasoning. This book overturns such thinking, demonstrating the coherence of James's efforts to develop a flexible but rigorous framework for individuals and societies seeking freedom, meaning, and justice in a world of interdependence, uncertainty, and change. “Enriched by a wealth of bibliographical documentation – the author has a solid grip on James’s unpublished materials and manuscripts, which he puts in productive dialogue with most well known pages of his work –, the book will be both a superb introduction to James’s practical philosophy for newcomers as well as an indispensable guide for more seasoned readers of his oeuvre.” (Sarin Marchetti, European Journal of Pragmatism and American Philosophy, Vol. 7 (2), 2015) Trygve V.R.
