All of the senses are at the surfaces of the body and the perceived world is a model which summarises and predicts sensory correlations. You may have a direct experience of time, but space and spatiality are entirely constructed in the imagination. This includes the body as an object in space and its surfaces and senses as well. All you have is a sensorium responsive to movements of attention so as to appear spread out in a wholly fictitious dimension of depth. You can catch your mind at work more easily in the creation of empty space than in the objects which fill it. By first proposing this capacious nothing it allows things to appear as things. And in the same way the inner spaces, the space between you and what you are aware of, thoughts sensation, feelings, are fictions allowing something you think of as you to appear as mysteriously not-appearing.
