Apologetics tends to be regarded as the art and practice of defending the faith, articulating its tenets and systems both for the believer and for the world at large; but apologetics is really not a genre, but rather a kind of motive or impulse or process or goal. Apologetics might usually be an argument or an exposition, but, just as likely, it could be a song or a poem, a symphony or a story; sometimes it might even be a nod or a wink, a shrug or a sigh, if the right person is sighing or shrugging. To put it in the terms Lewis uses in "Meditation in a Toolshed," an essay first collected in the American anthology God in the Dock: apologetics involves both looking at, and looking along, not just seeing what's there, but seeing what's beyond it, even glimpsing what makes seeing possible--and how to get there.
