To see that Jane’s jumper is red and to believe that apples are wholesome are both mental states. These two states are also representational. To say that a mental state is representational is to say that it serves the function of being about something in the world, or that it takes the world to be a certain way. Perceptions and beliefs are representational states. To be in such states is to represent the world as being a certain way. The way a state represents the world as being is its representational content.
