I re-read "Robinson Crusoe", recently; it's a classic I haven't visited since I was a little boy. I was quite amazed at the extent to which religion played a role in the book. As a kid, I thought it was just a cool adventure story. I never even noticed all the religion, to be honest. As an adult, living in these times, it really stood out. To be sure, religion can be a comfort to many people stranded on a desert island and, when Bibles are pretty much the only books on hand, it's got to influence your thinking. I think what really made me take notice, though, was the way that religion, the belief in God, the absolute sense of certainty and right, guided Robinson Crusoe's actions. Even though he struggled with his faith, it eventually became the driving force behind most of his decisions. Those were different times, when the book was written. I can't imagine such a pervasive presence in any modern work of literature.
