There are two, I argue, and given computationalism, this has implications for what it is to implement a computation. I then consider what happens when a computation is implemented in a system that either uses unreliable components or possesses varying degrees of parallelism. I show that in some of these cases there can be, in a deep and intriguing sense, a fractional (non-integer) number of qualitatively identical phenomenal experiences. This, in turn, has implications for what lessons one should draw from neural replacement scenarios such as Chalmers' “Fading Qualia” thought experiment.", pages = "185-200(16)", url = "http://www.ingentaconnect.com/content/klu/mind/2006/00000016/00000002/00009036" doi = "doi:10.1007/s11023-006-9036-0" }
