Anthropologically, money should be defined as a semantic system, broadly similar to language; writing, or weights and measures. These systems differ mainly in the purposes served and the signs employed. Language and writing serve the purpose of the communication of ideas, weights and measures that of quantitative physical relationship. As to signs, language uses oral sounds; writing employs ideograms or visual characters; weights and measures, on the other hand, use physical objects as the basis of symbols.
― Karl Polanyi
