Yup, books are a large part of what I consider to be my "essence". From Carl Sagan's scientific thinking, to classic writers such as Dostoevsky, Homer (gotta love the greeks) and Shakespeare. We all know the benefits of reading (improved memory, focus, empathy). But, in my opinion, the greatest benefit is: you become wiser. One good book equals a lifetime of knowledge/experience. When you read The Odyssey, for example, you not only enjoy one of the greatest stories ever written, but you understand what people from the past (greeks, in this case) believed in, how they behaved, what were their worries, their idea of the Cosmos, and you start to compare that to your own ideas and beliefs. You become humble, you become curious, you become wiser.
However, of course, knowing too much is not bound to make you happy, unfortunately.
Do you know Carl Sagan? What you wrote reminded me of one of the episodes from his tv series, Cosmos. Check it out, he speaks in such a passionate manner:
Also, did you get a digital copy of a discourse on voluntary death? If so, could you PLEASE send me the file/link? I've been looking for this book for months now, but the only pdfs I find are made of photos, terrible to read.
Also, what were the books recommended to you on suicide? I've read Suicide, by edouard levé, and it was so intimate I felt it was me he was writing about. (He committed suicide short after writing it, which makes it even more interesting)
