I've written my 4th paper on CS Lewis - on Miracles. I put my class on hold while I went to Cambodia and now I'm trying to finish it. Lewis and jetlag don't mix, by the way, but I managed to read the book in the past few days, and write the paper this morning, due immediately. I really love academia as a hobby. I don't think I'd do very well with it as the main focus - eventually I'd wonder when are we going to stop talking about things and actually live them. The perpetual existance in the theoretical would drive me up the wall, I'd imagine. For me debate is fun, but only so long as it leads to something practical in the end. What's the point of solving the mysteries of the universe if it doesn't change the way you live your life.
My next paper is on Mere Christianity -- Lewis' most widely read non-fiction book. I'm looking forward to reading it again, as I've quoted it a lot in previous papers on Lewis.
