This book was recommended to me by my polisci prof my sophmore year of college. It was this book which convinced me to study Political Philosophy. This book is a life altering book,(I don't review any that aren't). Even the chapter, The Grand Inquisitor, read and studied by itself, without the rest of the novel, has a lot to teach you about faith and mankind.
I have read thousands of books in my 64+ years, and Hugo's "Les Miserables" and Dostoevsky's "Brothers Karamazov" are the two best. One chapter, entitled "The Grand Inquisitor," in Dostoevsky's book affected me deeply.
