playfulness becomes central and the actual achievement of order and meaning becomes unlikely. Gertrude Stein's playful experiment with metafiction and genre in The Autobiography of Alice B. Toklas (1933) has been interpreted as postmodern. Shift to postmodernism As with all stylistic eras, no definite dates exist for the rise and fall of postmodernism's popularity. 1941, the year in which Irish novelist James Joyce and English novelist Virginia Woolf both died, is sometimes used as a rough boundary for postmodernism's start. Irish novelist Flann O'Brien completed The Third Policeman in 1939. It was rejected for publication and remained supposedly lost until published posthumously in 1967. A revised version called The Dalkey Archive was published before the original in 1964, two years before O'Brien died. Notwithstanding its dilatory appearance, the literary theorist Keith Hopper regards The Third Policeman as one of the first of that genre they call the postmodern novel. The prefix "post", however, does not necessarily imply a new era. Rather, it could also indicate a reaction against modernism in the wake of the Second World War (with its disrespect for human rights, just confirmed in the Geneva Convention, through the rape of Nanking, the Bataan Death March, the atomic bombings of Hiroshima and Nagasaki, the Holocaust, the bombing of Dresden, the Katyn massacre, the fire-bombing of Tokyo, and Japanese American internment). It could also imply a reaction to significant post-war events: the beginning of the Cold War, the Civil Rights Movement, postcolonialism (Postcolonial literature), and the rise of the personal computer (Cyberpunk and Hypertext fiction). Some further argue that the beginning of postmodern literature could be marked by significant publications or literary events. For example, some mark the beginning of postmodernism with the first publication of John Hawkes' The Cannibal in 1949, the first performance of En attendant Godot in 1953 (Waiting for Godot, 1955), the first publication of Howl in 1956 or of Naked Lunch in 1959. For others the beginning is marked by moments in critical theory: Jacques Derrida's "Structure, Sign, and Play" lecture in 1966 or as late as Ihab Hassan's usage in The Dismemberment of Orpheus in 1971. Brian McHale details his main thesis on this shift, although many postmodern works have developed out of modernism, modernism is characterised by an epistemological dominant while postmodern works are primarily concerned with questions of ontology.
