The other day I got into a debate on twitter about the morality of sharing ebooks. Someone was posting free copies of Roger Zelazny’s books on kindle, and I replied that I was entitled to ebooks of the printed books I own. This writer challenged that assertion and asked for an argument. I refused to engage in his Empire-inflected moralizing, that the writer owned the medium his story is printed on, and used the Ship of Theseus example to deconstruct the notion of ownership.
