Done.
I've finished my thesis on Lewis' metaphysics. I'll make it available online as soon as I've found out that I'm allowed to do so. (Only "unpublished books" are accepted at the contest, and I don't know if online publication counts as publication.) Anyway, it's German, and doesn't contain many new ideas, especially if you've been reading my blog for the last couple of months.
Next, I have to find out how to register the thesis at my university. Then I will officially be given 4 months to finish it. I also have to find out if it's okay to hand in the finished thesis before registering.
