I am posting a couple of articles about metaphor. The first is more accessible, it brings out how we use metaphors in daily life. The second is by Nietzsche and is a really interesting theoretical take on language, its origin and so on. It talks about how all language is based on a metaphorical not literal use of words–it is one of my favourites of his and I would recommend it highly if you are interested in that kind of thing even if you haven’t read much philosophy.
