In the Metaphysics of Quality the world is composed of three things: mind, matter and Quality. Because something is not located in the object does not mean that it has to be located in your mind. Quality cannot be independently derived form either mind or matter. But it can be derived from the relationship of mind and matter with each other. Quality occurs at the point at which subject and object meet. Quality is not a thing. It is an event.
