Being first and foremost a philosopher by heart my William James readings has been like meeting a freind, with whom I not only share opinions, but the more a freind in philosophy, who's personally engaged in solving profound philosophcal questions and in consequence aim for tranparency. Thus, having found myself a diciple of the William James thinking, my appraisals and recommendation can be nothing short of "countles stars" and a "must read".It's a massive book of more than 1300 pages, which from the hand of James wasn't meant for a single publication. The various parts can be read independantly. I myself have read all but "The Varieties of Religious Experience", why my recommendations doesn't include that part.The overall subjects of the book are "Pragmatism".William James determines pragmatism as a necessary philosophical format, which proposes itself as a mediator between the religious and the emperic mindsets by forming the pragmatic corridor, in which scientific and theoretical developments in general can meet and by means of the pragmatic adequacy criteria submit themselves for concept validation and cross-disciplinary exploration.Pragmatism, though its tendencies had always existed in philosophy, was at the time a relatively recent though international development that profoundly challenged the ruling rationalist mindset. As always, when profound paradigms are challenged, also the pragmatist point of view became subject of fierce and deep discussions,which on the other hand turned out contributing to the clarification of a wide range of philosofical positions. And this is exactly why this book is worth while reading. The writings of William James not only displays the contemporary discussion, by his excellent intellect and comprehensive knowledge of the history of philosophy his writings simultaneously becomes a kaleidoscope to the world of philosophical thinking in general, to the universe of the pragmatist mindset and to the differences between the pragmatist and rationalist accounts.Being a collection of writings the same subjects are dealt with more times. Due to a particular interest I first read "Some Problems of Philosophy". This part is perhaps the most stringent treatment of the problems dealt with and may also to others be a good starting point. However, not going back into the lectures and the contemporary discussions you'll miss some of the greater and most rewarding parts of the book.
