A logical paradox resembling the liar paradox but using, instead of a single sentence, an infinite sequence of statements, each referring to the truth values of the later statements in the sequence, and thus attempting to avoid circularity.

plural of paradox of thrift

(economics) A paradox of economics, stating that an increase in autonomous saving leads to a decrease in aggregate demand and thus a decrease in gross output which will in turn lower total saving: narrowly speaking, total saving may fall because of individuals' attempts to increase their saving, and, broadly speaking, increase in saving may be harmful to an economy.

A particular paradox in mathematical logic; the type-theoretic analogue of Russell's paradox from set theory.

plural of Epimenides paradox

Synonym of unexpected hanging paradox

A form of self-referential logical paradox associated with statements of the form "All Cretans are liars" (spoken by Epimenedes, himself a Cretan, who must therefore be lying).

Synonym of Curry's paradox

(philosophy) The paradox that (i) people have emotional responses to fictitious events, and (ii) one must believe that something truly exists in order to be emotionally moved by it, but (iii) nobody who considers an event to be fictitious can also believe it to be real.

A paradox that occurs in naive set theory or naive logics, and allows the derivation of an arbitrary sentence from a self-referring sentence and some apparently innocuous logical deduction rules.
