WitrynaInterestingly, a similar difficulty affects the attempt of amending the naive comprehension schema as well as the schema for introducing contextual definitions underlying the Fregean definition of natural number (this remark is due to Boolos and Heck; see [Boolos, 1998, pp. 232-233]).

Witrynaby application of the Naive Comprehension schema: given any formula ϕ in the language of set theory, we form the class of all the x’s that satisfy ϕ, that is, {x ϕ(x)}. Then we have that R ∈ R if and only if R ∈ R.
