Re: Surely money itself is the great invention?
But isn't money just another form of information? And for that matter, aren't all things connected with money (bookkeeping, limited liability companies and so on) just a subset of information flow? Money being information on the value on what I (or my ancestors etc) have contributed to the system and, if rules are followed, what I can expect to receive in exchange for that money.
In a sense, the Enlightenment is also part of that information flow - things happen because there are various rules that are followed and what happened yesterday will happen today and tomorrow. Gravity being a good example - we know it happens and can measure it within the limits of quantum mechanics, but we know less about the how of gravity than we know about the how of evolution.
Getting back to money, instead of me claiming the grain you grew because one of my foremothers was shagged by a local god, you can tell me to eff off because you grew it on your own land and you then exchange the grain for filthy lucre.
