Physicist Alan Sokal achieved a moment of fame by announcing that he had succeeded in publishing an article in the cultural studies journal Social Text, which was 'sprinkled with nonsense' about developments in quantum gravity physics that supposedly converge with post- modernist themes. Sokal announced his hoax in an article in the liter ary magazine Lingua Franca. This touched off an intense flurry of commentary. Many commentators praised Sokal for exposing shoddy editorial standards in the cultural studies field, while others (...) denounced him for committing scientific fraud. With few exceptions, both Sokal's celebrants and detractors accepted his claim that he did not believe what he said in the Social Text article. Under the circumstances, it is puzzling that they took seriously what he said in Lingua Franca, and did not con sider that he was once again 'successfully pretending to be himself'. In this paper, I suggest that the Lingua Franca article also achieved a parody, and that those who took Sokal seriously were once again taken in by the voice of scientific authority. (shrink)
