One of Glyn Davies's main motives for writing the book was that, as he writes in his preface around the next corner there may be lying in wait apparently quite novel problems which in all probability bear a basic similarity to those that have already been tackled with varying degrees of success or failure in other times and other places. Furthermore he is of the opinion that economists, especially monetarists, tend to overestimate the purely economic, narrow and technical functions of money and have placed insufficient emphasis on its wider social, institutional and psychological aspects.
