Talk:Predicate
From Maths
In the framework of the set theory like ZF(C), one does not write that x belongs to a predicate, since in a set theory like NB(G) the class of all such x need not be a set, and in ZF(C) there is no notion of class. Boris (talk) 19:05, 18 March 2016 (UTC)
- I like the axiomatic approach of ZF (I'm scared of C!) so I am confident with sets, I am not sure what a class is[1], do you have any recommended reading? Alec (talk) 19:16, 18 March 2016 (UTC)
- At the moment I think of a class as "a collection defined to have a property, which is shown to be non empty".
