"That is, for any random set of relations with enough complexity to represent a human mind, Egan claims, there exists an exotic encoding scheme that can interpret this set of relations as representing any arbitrary function, including the function that you would call “I”."

Since I assume that solipsism is a fallicy, I don't find this philosophical position all that useful.
