The number of unknown paradoxes
Published online by Cambridge University Press: 17 April 2020
Extract
‘A logical theory may be tested by its capacity for dealing with puzzles, and it is a wholesome plan, in thinking about logic, to stock the mind with as many puzzles as possible, since these serve much the same purpose as is served by experiments in physical science’.
How many paradoxes are there? By 1920, Bertrand Russell's star student had concluded that there are few or zero paradoxes in philosophy. Most philosophical propositions ‘are not false but nonsensical’.

3 The number of paradoxes discussed in general books on paradoxes varies. For example, Clark, MichaelParadoxes from A to Z, 3rd ed. (London: Routledge, 2012) discusses 93CrossRefGoogle Scholar; Rescher, NicholasParadoxes: Their Roots, Range, and Resolution (Chicago: Open Court, 2001) discusses 146Google Scholar; Sainsbury, MarkParadoxes, 3rd ed. (Cambridge: Cambridge University Press, 2009) discusses 34CrossRefGoogle Scholar; Roy Sorensen, op. cit. note 1, discusses 29. Of course, these authors do not claim that the paradoxes they discuss are all there are, and they make no claims for what the future holds.
4 This proposal is similar to, though distinct from, Rescher's, op. cit. note 1, 6. ‘Minimal’ is to prevent inflating the count of paradoxes by adding irrelevant sentences to a paradoxical set.
5 The graveyard includes paradoxes that now count as scientific corpses such as the Copernican paradox that the earth orbits the sun. Russell thought progress in ‘philosophy’ is disguised by the requirement that philosophy be speculative rather than settled. We leave the body count to historians.
