It's a difficult business, creating a new, alternative civilization.

Consensus isn't just about agreement. It's about changing things around: You get a proposal, you work something out, people foresee problems, you do creative synthesis. At the end of it, you come up with something that everyone thinks is okay. Most people like it, and nobody hates it.

If you look at history, there seems to be a regular pattern: the country with the most powerful military also happens to be the one with the world trade currency. That gives them an enormous economic advantage, which causes goods to flow into their country.

It affects every aspect of our lives, is often said to be the root of all evil, and the analysis of the world that it makes possible - what we call 'the economy' - is so important to us that economists have become the high priests of our society.

Money has always been a particular problem for revolutionaries and anti-capitalists. What will money look like 'after the revolution'? How will it function? Will it exist at all?
