I defended my dissertation a little while ago. This means that I finished writing it quite a while ago—months ago. During the months between finishing and defending, managed to I get a lot of work done; I made major revisions on a paper I'd been working on for a while and completely wrote another paper. But since the defense, I've been struggling. I'm having a lot of trouble deciding what I want to do next. One thing I don't want to do is to revise chapters into publishable papers. Oh my God. Maybe later, but I kind of hope not.
This strikes me as normal, I guess—at least, I’d be pretty surprised if I were the only person who reacted to finishing a major project this way. But the thing that’s weird about it is, I actually finished the project a long time ago, and I was fine for most of that time. It’s only now that I’ve defended that the lethargy has set in. I dunno.
I’ll say this, though. Writing the dissertation made me a lot better at philosophy. As I was studying for the defense, I (of course) reread chapters I wrote years ago for the first time since I finished them. It was a shocking experience. The change in quality of writing, argument, and general sophistication between the first chapter I wrote and the last was astonishing to me; I am a much better philosopher now than I was when I started writing. Dissertating, like science, works.
