1st Reading: Plato: The Cave

4th Reading: Your fourth reading is by John Locke. The Locke reading in the book is a composite of snippets from a large book, An Essay Concerning Human Understanding. The following links are the best I could do to get you roughly equivalent material:
Locke (Essay II, Chapter i, sections 1-10, 23-25; Chapter ii; Chapter vii, sections 7-17)
Locke (Essay IV, Chapter ii, sections 1-14; Chapter iii, sections 1-7, 21 and 31)
