Historical Introduction to Epistemology? Suggestions, please!

I have twice now taught “Introduction to Theory of Knowledge” using classic historical texts. Both times I used Plato’s Theaetetus, Descartes’ Meditations and some selections from Reid. It looks like I will be teaching the class again in Fall 2014, and I want to approach it historically one again. However, I am thinking of modifying some of the readings. More Plato? (E.g., Meno, Phaedo, Republic) More Descartes? (E.g., the Discourse on Method) Drop the Reid and substitute something else?

The course is at the second year level. Many Majors take it as part of their program. But there are also lots of students for whom Philosophy is nearly brand new.

I am canvassing suggestions.
