E.g. we do not judge that Socrates = Socrates. In a way, we judge an ambiguous case of propositional function (propositional function) "A is A". >Propositional function. ad I 111f Containment/Identity/Element relations/Equal sign/Epsilon/Principia Mathematica/(s): therefore containment must not be the same as identity, otherwise from the right i'x = i'x follows the wrong i'x ε i'x i.e., a class may not be identical with its (perhaps only) element. >Element relation, >Equal sign. 1.
