Thomas Wallgren's book Transformative Philosophy is a remarkable, important achievement in modern philosophy…. The importance of the book is that it manages to portray significant positions and debates in modern philosophy both in their own modern terms and as examples of how to deal with some deep and basic problems that have always characterized serious philosophy since Socrates. There is hardly any other book available that analyses "what philosophy is about today" with such profundity as this book. It reveals a fine and valuable insight into important parts of both modern analytic and modern continental philosophy…. It is a book that one can recommend to not only to students of philosophy but to learned scholars, since few living philosophers have managed, with excellence, to present the aspirations of modern philosophy as still answering to the historical roots and original ambitions of the enterprise.
