There is a reflexive paradox associated with self-deception, and a variety of theories have been proposed in response, to explain self-deception. The study of reflexive paradoxes has been fruitful in the history of philosophy. Such a paradox may appear to be no more than a minor puzzle, which we will easily be able to mop up after having formulated solutions to more major problems. Sometimes the minor puzzle turns out to be surprisingly resistant to our "mopping up" operations; it may (...) force us to re-think our major theories. For example the "truth-teller" paradox and other paradoxes of self-reference have been viewed initially as minor puzzles, while later on they have provoked major theories, e.g. theories of truth; in mathematics, Godel's theorem.
