@Ein: Thanks, I've been looking forward to picking up Kuhn's book since last summer when a footnote led me to it. I tackled Schopenhauer's World as Will and Idea(or presentation, as my translation denoted it), but got bored with it 200 or so pages in. Essay on the Freedom of the Will is really brief, like 60 pages, and was the work that put him on the map, from what I've heard, so it should be a fun read. You may like Berger and Luckmann's work. I'm not sure if I would call it ground breaking, but it was important. The term "social construction" was coined in it.
@dak: Somewhat, I just started reading Kuhn's work yesterday, but my excitement over seeing Ein's work of Hayek prompted me to post. That's how my foreign policy professor spoke of Clausewitz. He called it one of his favorite books, just behind The Art of War and The Landmark Thucydides (he's a retired Coast Guard Captain, so all of his favorites are along the same line) and gave me a new copy for free.
