Iscuss epistemology and the legend of the Sphinx in Oedipus Rex. How do these monsters both guard and reveal knowledge?

Epistemology (i/E?E?pE?stEE?mE lEdE i/; from Greek a??II?I?I I®I?I· (epistA mA ), meaning ”knowledge, science”, and I»I?I?I?I (logos), meaning Study of”) is the branch of philosophy concerned with the nature and scope (limitations) of knowledge.[1] It addresses the questions:
What is knowledge?
How is knowledge acquired?
How do we know what we know?


Thesis: The idea of pharmakos in Oedipus Rex is embodied in the interaction between the sphinx and Oedipus and how the sphinx guards and reveals knowledge. Pharmakos is the idea that there is a duality to things; that an item can be both a cure and a poison. The sphinx is used as a pharmakos in Oedipus Rex because not only does her physical appearance portray a duality, but also her riddles conceal knowledge in their ambiguity, but also in a sense, reveal truth concerning Oedipus and the Greek society.
