You know you've deemed a book to be very important to you if you shape your weekend schedule around reading it. I've been working on Jean-Paul Sartre's Being and Nothingness since late August*, and I'm finally nearing the end of it. Since I tend to read very well on long stretches of public transportation, I decided to make two shopping trips out to the 'burbs so that I could get a little shopping done, and a lot of reading done (105 pages over the course of the weekend). I'll write more about this text later, but I have to say that the five pages I read yesterday on "Freedom and Responsibility"** were among the most enlightening, profound and ultimately useful words in philosophy that I've ever read, and they made the rest of the book worth struggling through.
*corrected; I originally wrote "early September".
**Section III of "Chapter One: Being and Doing: Freedom" in "Part Four: Having, Doing and Being".)
