I was looking at earlier questions in your Perception section and was intrigued by Prof. Moore's answer to the one of the car driving down the road and appearing to get smaller with distance (http://www.askphilosophers.org/question/548). He said that the size of the real car is an intrinsic property of the car, but the size of the apparent car is a relational property of the real car, and subtly so. I wish he would explain this subtlety, because I just don't get it. I can see that the distance between the car and the observer is a relational property: the relation is the distance, and its terms are the apparent car and the observer. But how can the apparent size of the car be a relation? The apparent car has an apparent size which, it seems to me, is just as much an intrinsic property of the apparent car as the real size of the real car is an intrinsic property of the real car. I am also fascinated by the question that he did not answer: at what distance must the car be for us to see its real size? Please tell me!
