I can't get over how interesting stories are. I just love reading, and hearing, and watching, and telling stories. I don't really care where they're from, or how true they are. I almost feel like a story is truer than the actual events.
Ultimately our pasts are just the stories we tell about the past. I often feel like I've integrated some of the bits of stories I've read and seen into the fabric of my own life. Those bits of me that are most like Holden Caulfeild are that way because of and interaction between how I am and how the book made me.
There are a few important functions of language. One asks for things, and passes on information. As far as pure necessity goes, it's difficult to figure out what stories are for. Of course there are those elements of passing on knowledge and instilling values, but I suppose that's what I was getting at. We use stories to encode our societal values, and to suggest what is expected of each individual. We use stories as a way of keeping entertained.
There are a lot of wonderful things we use stories for.
I've more to say, but will get to it later. This post felt like pure speculation, and not in a good way. But such things happen.
