"Seaford’s book deals with the origins of Greek philosophy. According to the author, its purpose is to explain “the advent of the idea of the universe as an intelligible order subject to the uniformity of impersonal power. More specifically… [to explain] the counter-intuitive idea of a single substance underlying the plurality of things manifest to the senses” (175, emphasis in original). The author thus intends to focus not on explicating the beliefs and arguments of early Greek philosophers, but rather on ascertaining “why… they [held] those extraordinary fundamental beliefs about the world” (10, emphasis in original). Seaford finds his explanation in the rapid development and pervasive use of coined money in Greece during the sixth century B.C."
