Free Religion & Philosophy Textbooks
In my mind, the study of religions and philosophy seek the same thing – answers to questions. Of course, in pursuing those answers we quite frequently come up with even more questions. From Aristotle and his contemporaries to today’s modern scholars, educators have been leading their students to discovering both answers and new questions.
Leading the online textbook revolution in the field is a professor of Philosophy at Queensborough Community College. Philip A. Pecorino, Ph.D was among the first to make his works available for free online to both his students and all the students of the world. His works are among the many free online religion and philosophy textbooks that can be found here on The Free Textbook List.
