 Examples of prominent theories of truth that supply Curry-incompleteness responses to Curry’s paradox include  Tarski’s hierarchical theory, the   revision theory of truth  (Gupta &amp; Belnap 1993) and the contextualist approaches (Burge 1979, Simmons 1993, and  Glanzberg 2001, 2004). These theories all  restrict the “naive” transparency principle  (Truth).  For an overview, see the entry on the   Liar paradox.  In the context of set theory Curry-incompleteness responses include Russellian type theories and various theories that restrict the  “naive” set abstraction principle  (Set).  See the entries on  Russell’s paradox  and  alternative axiomatic set theories.
