Classes I 289
Class abstraction attributed to singular descriptions: (iy)(x)(x from y iff ..x..) - instead: x^(..x..) - does not work for intensional abstraction.
Difference classes/properties: classes are identical with the same elements - properties not yet identical if they are assigned to the same things.

Classes: one could reinterpret all classes in their complement: "no element of .." - you would never notice anything - Bottom layer: every relative clause, every general term determines a class.

Russell (Principia Mathematica) classes are things: they must not be confused with the concept of class - However: paradoxes also apply to class terms and propositional functions not only for classes -
Incomplete symbols (explanation by use) - to explain away classes.

Classes/Quine: simplify our access to physics - but are still a myth.

Classes/Quine: no accumulations or collections! E.g. the class of stones in a pile cannot be identified with the pile: otherwise another class could also be identified with the same pile: e.g. the class of stone molecules in the pile - the validity theory applies to classes, but not to the individual sentences - predicates are not names of classes, classes are the extension of predicates - classes are assumed to be pre-existent (see below).

Classes/relations/Quine: are real objects if values ​​of bound variables.

Class/individuals/Quine: everything is class! if we understand individuals to be identical to their class of one (i.e. not elementless).
