Harold Bloom argues for the importance of the Western canon in his book The Western Canon. He claims that aesthetic value is autonomous from politics and morality, and that originality is key to inclusion in the canon. Bloom analyzes 26 influential Western writers from Shakespeare to Beckett. He sees the canon as providing a standard of cultural and individual thinking that is rarely expanded. However, some criticize focusing too much on tradition and not being open to new works or social perspectives.
