Philosophy of mind explores questions about the nature of the mind and mental states and events – perceptual experiences, beliefs, desires, emotions, sensations, and so on. What is the mind? Is it an immaterial substance? Is it the brain? Is it something like a computer? Is the idea of the mind nothing but a myth? In considering these and related questions we will pay particular attention to two central features of the mind: (i) that mental states play a central role in explaining behaviour (for example, my desire for coffee helps explain why I’m heading to the cafeteria); (ii) that some mental states are conscious: there is something it is like to feel pain, taste chocolate, or see a sunset. We will study the various ways in which philosophers have tried to give an account of the mind that makes sense of these features.
