Query: Why this book is a collectors item

Quite simply, amongst the best books I have read.Gottlieb is a good book to read if you have just read Will Durant's story of Philosophy. Its the book you would read once you have a broad idea of the various philosophies and their timelines, and are now ready to step into the story of the men behind it. It is the book you would read before you start reading Plato's Republic... or dialogues.The story begins with the Greeks and shows us what each person behind the philosophy was, it speaks of the love Plato had for Aristotle, the greatness of Pythagoras, the cynics, the epicureans... and just about every other greek school of thought that existed, from there on - it briskly moves to philosphical schools and thoughts at the time of the renaissance.It is a book I have bought, and it proudly adorns my shelves along with other classics. Go ahead and buy it now, before it becomes 'out of print' ...
