noted: “More than once in history the discovery of paradox has been the occasion for major reconstruction at the foundation of thought.” Russell’s paradox provided for precisely such an occasion. Russell’s Paradox The person who essentially single-handedly founded the theory of sets was the German mathematician Georg Cantor. Sets, or classes, quickly proved

set this way: S is the set of all sets that are not members of themselves. This version is known as Russell’s paradox. It cannot be dismissed as noise. To eliminate Russell’s paradox Russell took drastic measures. The enabling factor seemed to be the peculiar recursion within the offending statement: the idea of sets

is not, then by definition it should be included. But if it is included, that means it is a member of itself, so should not. “Russell’s Paradox,” as it came to be known, echoed paradoxes that had been around since antiquity. The prototype is the Liar’s Paradox, attributed to Epimenides the

not teaspoons is one of the things that are not teaspoons.’ It was this curious and apparently innocuous observation that led to the catastrophic paradox. Russell’s paradox is often explained using the tale of the meticulous librarian. One day, while wandering between the shelves, the librarian discovers a collection of catalogues. There

, is like the Achilles paradox: with the loss of unity, the attempt is made to recapture it by summing parts, but necessarily fails. 7. Cf. Russell’s paradox: the set of all sets that are not members of themselves leads inexorably to a contradiction. If such a set were a member of itself

there are infinitely many. Mathematicians had embraced Cantor’s theory as a powerful tool for manipulating and proving theorems about such sets of infinite size. Russell’s paradox, however, threatened to deal a far more serious blow to set theory than earlier ideological objections. The problem was this: consider a set of objects

quantifiers. The terms "predicative" and "impredicative" originate in logic. Quine (1987) offers a lucid summary of their history: In exchanges with Henri Poincaré...Russell attributed [Russell's] paradox tentatively to what he called a vicious-circle fallacy. The "fallacy" consisted in specifying a class by a membership condition that makes reference directly or

indirectly to a range of classes one of which is the very class that is being specified. For instance the membership condition behind Russell's Paradox is non-self-membership: x not a member of x. The paradox comes of letting the x of the membership condition be, among other things

attributes of a myth. Cantor’s set theory is inconsistent, mathematicians understanding at once that its fecundity and its inconsistency were deeply linked. There is Russell’s paradox, the best known among a collection of paradoxes and the easiest to state. If sets are subject only to some principle of free construction, then
