well, i read about the russell's paradox recently. but what i was wondering is "how is the paradox resolved?"
can you please give an example of what cannot be allowed to be called a set (to avoid the paradox)?matt grime said:By disallowing unrestricted comprehension. I.e. restricting what is allowed to be called a set.
It's an algebraic sort of thing: ZFC explicitly posits the existence of only two sets: the empty set, and the set of natural numbers... but it provides us with a lot of ways to build new sets out of old sets.all of those went above my head. can you give some easier examples?
