Last Wednesday, I was consulting with my undergraduate advisor, Prof. Marc Kleijwegt, who lent to me his book, Money and the Early Greek Mind: Homer, Philosophy, Tragedy by Richard Seaford. Judge for yourself how similar the following quote from the book's abstract sounds to my above hypothesis:
How were the Greeks of the sixth century BC able to invent philosophy and tragedy? In this book Richard Seaford argues that a large part of the answer can be found in another momentous development, the invention and rapid spread of coinage, which produced the first thoroughly monetised society. By transforming social relations, monetisation contributed to the ideas of the universe as an impersonal system (presocratic philosophy) and of the individual alienated from his own kin and from the gods (in tragedy).
I have not read Seaford's book yet, but I have a feeling it will be crucial to shaping the focus of my senior thesis. As he has "utilized" my ideas, I look forward to observing and perhaps utilizing the methodology he uses to explore Greek philosophy and then reapplying that to ancient Hebrew, Indian and Chinese thought. My senior thesis is shaping up to be a happy marriage between my two interests in college: ancient intellectual history and economics.
