However tawdry their origins, the creation of new media of exchange – coinage appeared almost simultaneously in Greece, India, and China. It appears to have had profound intellectual effects. Some have even gone so far as to argue that Greek philosophy¹ was itself made possible by conceptual innovations introduced by coinage [and markets]. The most remarkable pattern, though, is the emergence, in almost the exact times and places where one also sees the early spread of coinage, of what were to become modern world religions: prophetic Judaism, Christianity, Buddhism, Jainism, Confucianism, Taoism, and eventually, Islam. While the precise links are yet to be fully explored, in certain ways, these religions appear to have arisen in direct reaction to the logic of the market. To put the matter somewhat crudely: if one relegates a certain social space simply to the selfish acquisition of material things, it is almost inevitable that soon someone else will come to set aside another domain in which to preach that, from the perspective of ultimate values, material things are unimportant, and selfishness – or even the self – illusory.
