A Brief History of Money

James Surowiecki on the, abstraction of money:

Kublai Khan was ahead of his time: He recognized that what matters about money is not what it looks like, or even what it’s backed by, but whether people believe in it enough to use it. Today, that concept is the foundation of all modern monetary systems, which are built on nothing more than governments’ support of and people’s faith in them. Money is, in other words, a complete abstraction—one that we are all intimately familiar with but whose growing complexity defies our comprehension.
