. . . I’m trained in history, rather than English or media studies. There’s a difference between the kind of arguments that are allowed in the two fields, specifically with respect to evidence and claims about causation. Scholarship in English tends to be more self-consciously performative, and more concerned with joining up apparently unconnected things in a provocative or original way. I’m reminded of a workshop at Penn where Rob Kohler asked a visiting English professor “How would you know if an argument of this kind had gone off the rails and fallen off the cliff?” His suggestion was that you couldn’t, that the aesthetic standards at work meant that almost any connection of conclusion to evidence would be equally valid.
