This week we continue our exploration of the the question "What can I know?" We have already seen from the example of Socrates' defense speech that true wisdom consists of a humble acknowledgement of our own ignorance. In a way, the wise person is the one who is willing to admit, "I don't know," and that admission is the gateway to new knowledge. It opens our minds.

Socrates's student Plato goes somewhat further, and in his dialogue The Republic, uses an allegory to describe the process of Enlightenment and then uses the image of a divided line to describe the different types and kinds of knowledge human beings are capable of acquiring. This week's independent study is all about Plato's theory of knowledge. Enjoy the exploration!
