On the basis of arguments showing that none of the most influential analyses of Moore's paradox yields a successful resolution of the problem, a new analysis of it is offered. It is argued that, in attempting to render verdicts of either inconsistency or self‐contradiction or self‐refutation, those analyses have all failed to satisfactorily explain why a Moore‐paradoxical proposition is such that it cannot be rationally believed. According to the proposed solution put forward here, a Moore‐paradoxical proposition is one for which (...) the believer can have no non‐overridden evidence. the arguments for this claim make use of some of Peter Klein's views on epistemic defeasibility. It is further suggested that this proposal may have important meta‐epistemological implications. (shrink)

The mooronic solution to the surprise quiz paradox says students know there will be a surprise quiz one day this week but they lose this knowledge on the penultimate day. This is because ‘there will be a surprise quiz one day this week’ then becomes an instance of Moore's paradox. This view has surprising consequences. Furthermore, even though the surprise quiz announcement becomes an instance of Moore's paradox on the penultimate day, this does not prevent the students from knowing the (...) quiz is coming. I conclude that the first stage of the paradoxical argument succeeds and the mooronic solution fails. (shrink)

This paper proposes a game-theoretic solution of the surprise examination problem. It is argued that the game of “matching pennies” provides a useful model for the interaction of a teacher who wants her exam to be surprising and students who want to avoid being surprised. A distinction is drawn between prudential and evidential versions of the problem. In both, the teacher should not assign a probability of zero to giving the exam on the last day. This representation of the problem (...) provides a diagnosis of where the backwards induction argument, which “proves” that no surprise exam is possible, is mistaken. (shrink)

In this paper I consider the surprise examination paradox from a practical perspective, paying special attention to the communicative role of the teacher’s promise to the students. This perspective, which places the promise within a practice, rather than viewing it in the abstract, imposes constraints on adequate solutions to the paradox. In the light of these constraints, I examine various solutions which have been offered, and suggest two of my own.

The Surprise Exam Paradox continues to perplex and torment despite the many solutions that have been offered. This paper proposes to end the intrigue once and for all by refuting one of the central pillars of the Surprise Exam Paradox, the 'No Friday Argument,' which concludes that an exam given on the last day of the testing period cannot be a surprise. This refutation consists of three arguments, all of which are borrowed from the literature: the 'Unprojectible Announcement Argument,' the (...) 'Wright & Sudbury Argument,' and the 'Epistemic Blindspot Argument.' The reason that the Surprise Exam Paradox has persisted this long is not because any of these arguments is problematic. On the contrary, each of them is correct. The reason that it has persisted so long is because each argument is only part of the solution. The correct solution requires all three of them to be combined together. Once they are, we may see exactly why the No Friday Argument fails and therefore why we have a solution to the Surprise Exam Paradox that should stick. (shrink)

RÉSUMÉ: Les philosophes, au cours des cinquante dernières années, se sont efforcés de démontrer qu’un professeur peut, d’une manière cohérente et exacte, annoncer à ses étudiants qu’un examen surprise aura lieu lors d’une journée non spécifiée d’une période donnée, le problème étant qu’une telle annonce peut sembler s’annuler ellemême lorsqu’elle est soumise à une induction régressive. Deux grandes approches, l’une épistémique et l’autre logique, one été développées à ce propos. Le présent article adopte une approche logique, mais repose aussi d’une (...) manière cruciale sur une compréhension épistémique du problème, pour essayer de montrer que l’annonce du professeur peut effectivement être cohérente et exacte.

This paper offers a new solution to the Surprise Test Paradox. The paradox arises thanks to an ingenious argument that seems to show that surprise tests are impossible. My solution to the paradox states that it relies on a questionable closure principle. This closure principle says that if one knows something and competently deduces something else, one knows the further thing. This principle has been endorsed by John Hawthorne and Timothy Williamson, among others, and I trace its motivation back to (...) work by Alvin Goldman. I provide counterexamples to the principle and explain the flaw in the reasoning of those who defend it. (shrink)
