Five Dimensions of a Great Story (like LOTR)

Anyone who blogs on a regular basis, or on a semi-regular basis, probably enjoys writing and may fancy himself to be a writer to some degree.

Peter Kreeft, the author of The Philosophy of Tolkein: The Worldview Behind The Lord of the Rings, presents five dimensions that every great story has. Justin Taylor has helpfully posted the details with links to the author's website where one can hear him lecture on some themes from the book.

Lecture anyone?
