Class UNBOUNDED

Something in the universe of discourse that can't be a member of a set. Paradoxical beasts go here.

Axioms:

(<=> (Unbounded ?X) (Not (Bounded ?X)))

• Defined in theory: Kif-sets
• Source code: kif-sets.lisp

Notes:

• It would seem that the extension of this relation is empty, since there can exist no set containing any unbounded things.
