The premise here is rather basic: I need some material for an essay for a class and I chose suicide as the subject. I'm looking for philosophical texts (whether in book form or something that I can look up online) that deal with the issue so I can read through and compile various points of view for it. I have Hume's essay on suicide on hand and Nietzsche's work, albeit, I'd have to do some digging since I don't recall where he dealt directly with the issue. I also have Schopenhauer's 'On Suicide' on hand. Any other suggestions for material I should look up? Seneca is going to be used in the essay (I can find his works online) but I don't know where to go from there in terms of research.
