" Life is about embodiment, thought Maddie. This was a point that she had discussed wth Dad many times. To experience the world through the senses was different from simply having data about the world. The memory of his time in the world was what had kept her father sane after he had been turned into a brain in a jar. And in this way, oddly, Maddie came to have a glint of the difficulty Mist faced in explaining her world to Maddie. She tried to imagine what it was like to have never petted a puppy, to have never eperienced a tomato filled with June sunshine burst between the tongue and the palate, to have never felt the weight of gravity or the elation of being loved, and imagination failed her. She felt sorry for Mist, a ghost who could not even call upon the memory of an embodied existence. "
