If you are serious in your quest for the truth, you better be careful with your research. It is not enough to check Wikipedia or to do a Google search that leads to questionable sources. I recommend you check out Questia. Questia is an online library of books, magazines and journals. This is a tremendous value, whether you are in school, writing a book, or just trying to blog some reliable and accurate information. They likely have the book you are looking for and they also have a number of philosophy and religion journals available. If you are not sure, you can do a one day trial to see if it is worth it.
