 We have seen at least some approaches (e.g., McGee 1991; in some respects, T. Parsons 1984 and Soames 1999) reject the revenge problem, while some seek to solve it by additional apparatus (e.g., Field 2008). As we discuss further in  §4.3,  contextualist views such as those of Burge (1979), Glanzberg (2004a), and C. Parsons (1974) tend to see revenge not as a separate problem, but as the core Liar phenomenon. For more discussion about revenge and its nature, see the papers in Beall (ed.) (2008) and L. Shapiro (2006).
