 In effect, Curry (1942b) sketches two “methods of constructing” Curry sentences using his counterpart of (Property). He says that the first is “based on the Russell paradox”, while the second is “based on the Epimenides paradox”. Although both methods are property-theoretic, the first method yields a precursor of set-theoretic versions of Curry’s paradox, while the second yields a precursor of truth-theoretic versions.
