Since money was invented, there has been a debate about better ways of creating it and better rules to govern how it works - until the last generation, when it began to seem that the money system had been handed down by God and remained unchanged ever since. But the last few years have seen an increasingly powerful resurgence of interest in changing the system fundamentally, and bringing the monetary trends that affect all our lives under our control. Few realize that the debate has roots and a tradition, covering mainstream economists like Keynes and Hayek, statesmen like Lincoln, entrepreneurs like Ford and Soros, as well as the imaginative mavericks behind local currencies and e-money. This volume collects together some of their most influential writings to provide a handbook on a vital train of ideas, and a guide to a debate on changing money that is becoming increasingly important.
