The ecstasy of influence: A plagiarism
By Jonathan Lethem

excerto:

At the movies, my entertainment is sometimes lately preceded by a dire trailer, produced by the lobbying group called the Motion Picture Association of America, in which the purchasing of a bootleg copy of a Hollywood film is compared to the theft of a car or a handbag—and, as the bullying supertitles remind us, “You wouldn't steal a handbag!” This conflation forms an incitement to quit thinking. If I were to tell you that pirating DVDs or downloading music is in no way different from loaning a friend a book, my own arguments would be as ethically bankrupt as the MPAA's. The truth lies somewhere in the vast gray area between these two overstated positions. For a car or a handbag, once stolen, no longer is available to its owner, while the appropriation of an article of “intellectual property” leaves the original untouched. As Jefferson wrote, “He who receives an idea from me, receives instruction himself without lessening mine; as he who lights his taper at mine, receives light without darkening me.”
