Literary criticism is not an exact science. When you interpret a poem, novel, or film, how can you be sure your interpretation is correct? The truth is, you can’t. This can make a writer understandably nervous – or at the very least it can make you feel that you ought to acknowledge that your interpretation is only a possibility, not a certainty. So it is that essays often end up with interpretations that begin, “It could be argued that…,” or, “Perhaps the author is referring to…,” or, “It may be that…,” or other forms of these hedges.
