This book contains a critical essay/preface on the cultic nature of censorship in Roman Catholicism by David Christopher Lane, professor of philosophy at Mt. San Antonio College. The main body of the book is on the Roman Catholic Index of Forbidden Books, which banned such texts as Kant's Critique of Pure Reason and all books by David Hume. This text includes a list of banned books up to 1966. This is a fascinating glimpse into Catholic apologetics about how they justified censorsing books that are now considered classics.
