3.4 Metaphysics of mind
What do we mean by ‘mind’?
Features of mental states:
● All or at least some mental states have phenomenal properties
○ Some, but not all, philosophers use the term 'qualia' to refer to these properties, where 'qualia' are defined as 'intrinsic and
non-intentional phenomenal properties that are introspectively accessible'
● All or at least some mental states have intentional properties (ie intentionality).
