We are going to begin this series at its foundation—the IOU. The foundational capacity on which all finance is built is the capacity to make a promise. Specifically, the capacity to issue an IOU. Meaning: issuing a promise, most commonly a promise to pay a certain sum of money at a certain period in the future. It can also be a promise to accept an IOU in payment: for example a storekeeper can issue a token—or a gift card—which can be used to pay for items in the shop. Whatever its form, it's the ability to enter into an agreement promising something of value in the future which serves as the “cellular premise” of finance. In other words, finance at its most basic level flows from the right to contract.
