Philosophy of mind explores questions about the nature of the mind and mental states – states such as perceptual experiences, beliefs, desires, and emotions. What is the mind? Is it an immaterial substance? Is it the brain? Is it something like a computer? Might it just be a useful fiction? In considering these 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 marmite, 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.
