I understand that it's a method that ascribes purposes to things. I have heard people speak very highly and lowly of it. On the one hand people say it has greater explanatory power than cause and effect. On the other, it assumes purpose in a meaningless universe. So which is it? Is it a good framework?
I know nothing of it, but my Internet search fu makes me think it's useless as a tool of analysis.
Maybe there's some value on teleolgy as a tool of synthesis, like metaphors. Something to ease out communication when the details aren't particularly relevant.
