What is money?
In this rubric we explore some aspects of money that we think are vitally important. What is money, actually? How does it manage the trick, in one way or another, of representing value, worth? What transforms a bone, a coin, a piece of paper, a password or a fingerprint into an exchangeable surrogate of value? What is money, we have to seriously ask, as an idea?
