his paper is about three writers and one idea which they held in common—an idea with which they were all positively enchanted. The three are C. S. Lewis, G. K. Chesterton, and J. R. R. Tolkien. The one idea is a certain fairly general (but far from trivial) thesis about meaning or fulfillment in life—that is, in the life of created rational beings. I will state the idea and then comment briefly on some of its parts. It is this: that the fulfillment of rational creatures, in any (positive) degree, involves some activity of the soul which is performed as an end in itself and which has as its contemplated object some external good, where that activity does not entail either arrogating to oneself authority to which one does not have a right, or being remiss in the exercise of authority which one is obliged to exercise.
