Intentionality Definition. Intentional object= a mental object What I am thinking of, or desire or fear or whatever. Mental object means, an object in my mind Two key features 1. The object need not exist. I may fear a ghost or whatever The word 'object' doesn't mean that this is literally an object; It is an object of my mental concern This is why associations with physical objects misleading here The intentional object is the object of my thoughts Milton feared God. That identifies his mental object. It does not imply that God exists. That we fear, desire, admire, etc things does not by itself imply that these things exist. 2. Failure of transitivity Normally if x=y and y=z then x=z But not here An example. I fear Stalin's ghost, whom I think I see in the corner That figure in the corner is merely an actor. my former student But not true that I fear the actor These two features way of indicating the special status of mental objects 1. I can fear, desire, hate... things which don't exist 2. The failure of transitivity is illuminating. I think of things under a certain description, and the failure of identity indicates this Intentionality identifies consciousness. Intentional irreducible to Nonintentional Compare a nonmental case I hit Peter. and Peter is the kindest man in the room. Then I have hit the kindest man in the room even if I don't know that Contrast I dislike , fear, admire, love the kindest person in the room All these intentional verbs. I think Bill, a kind man, is in the room. I dislike Bill. I don't dislike Peter, even if in fact he is kindest man in the room. Oedipus desired the woman he met. But Oedipus didn't desire his mother Even though that woman= his mother To say, we think of (desire, hate, perceive....) a thing under a certain description is a way of identifying such mental objects
