One of the issues hinted at here and very critical at present is the issue of authorship. Where does any given idea come from? Who is responsible for it and how should they be recompensed? How can we even begin to work that out?
There's a lovely little book by an artist called Daniel Spoerri, called 'The Topology of Chance'. It was published in the sixties*. In it he looks at the plate of food on the table in front of him and traces every particle - including plate and cutlery - further and further back. Where was the plate made? Where did the clay come from? How is clay made? etc. What's so nice about it is that you realise that everything, even the most mundane thing, has roots going back and back to the dawn of time; and that almost every natural process somehow impacted on its development. The more I think about the genesis of 'creative work' the more I recall that book. Tracing where any piece of art or science comes from is astonishingly complex and ultimately futile - because even if you could name all the threads in that tapestry you can't retrospectively assess the relative value of them. It's chaos theory worked backwards. All of us who make our living from some notion of 'ownership' of ideas - like copyrights, for example - are starting to recognise this dilemma. Indeed, one of the big challenges of Entanglement is how we pay for things and get paid for them. It isn't a trival question: I imagine that our solutions to that problem will entail some new kinds of thinking that may lead us to a whole body of new philosophical ideas - economics leading philosophy. Wouldn't be the first time (whispers Karl Marx).
