Here is an excerpt:
It would seem instead that consciousness must be a property of some kind. It is certainly true that physical properties are not usually exhibited by simulations. A simulation of a waterfall is not wet, a simulation of a fire is not hot, and a virtual black hole is not going to spaghettify  you any time soon. However I think that there are some properties which are not physical in this way, and these may be preserved in virtualisation. Orderliness, complexity, elegance and even intelligent, intentional behavior can be just as evident in simulations as they are in physical things. I propose that such properties be called abstract properties.
