Part 6.3. Criticisms of the resemblance theory of perception and an introduction to idealism - that perceptions of the external world are all within the mind as ideas.

Part 6.2. Explores Berkeley's and Locke's arguments concerning the resemblance of qualities and objects; that the perceived qualities of objects exist only in the mind or whether secondary qualities are intrinsically part of the object.

Part 6.1. Introduces the problem of perception (and the distinction between the world and what we perceive), along with the concepts of primary and secondary qualities.

Part 5.4. Looks at the role the concept of knowledge plays in life, the different levels of knowledge we require in certain contexts and the return of scepticism over knowledge.

Part 5.3. The difference between internalist and externalist accounts of knowledge; whether we need external factors to justify knowledge or whether internal accounts are sufficient, and the Gettier cases.

Part 5.2. Explores the idea of conscious and unconscious knowledge (should a person know that they know something or does it not matter?) and the theory of justification of propositions and beliefs.

Part 5.1. Looks at the problem of knowledge; how can we know what we know, three types of knowledge and A J Ayer's two conditions for knowledge.
