PTC is my first book which I seriously read about philosophy. This is an excellent introduction to this difficult subject which will never reach the daily life if there is no effort in its popularization made by someone like Mr Warburton. He is successful in highlighting the theme of each classic work of a wide range from Plato's Republic to Wittgenstein's Philosophical Investigation. He never fails to present the argument of each philosopher from different angles and focus on the crux. The book in itself provides a great reading but if you follow the list of further reading of each chapter recommended by Mr Warburton, you even can learn more about the philosophers concerned. Some of the books as recommended are even classics of their own.
In passing, if you like to learn more about Mr Warburton's philosophy of the popularization of the subject, please do not miss an interview with him in another book New British Philosophy - The Interviews by the same publisher.
Warburton is one of my favorite philosophers. I thoroughly enjoyed all his books. This author has the gift of breaking down complex ideas and explaining them in a highly intelligible fashion. But while Warburton does not assume that his reader has a substantial background on the subject, his writings are not superficial, nor is his style condescending. This book is a great read for virtually anyone with a genuine interest in philosophy.
