|Description Levels: Levels result from dividing a domain into sub-domains, for which different rules for making statements are valid. Thus, e.g. other statements are made about sets than about their elements. See also metalanguage, object language, theories, metatheory, metalogic, metasemantics, meta-ethics, meta-level, paradoxes, order, 2nd order logic, higher order logic, HOL, completeness.|

|Description Levels||I 372
Level / abstract / Tugendhat: for predicates of a higher level (that classify abstract objects) there are no analogues at the level of quasi-predicates. But there are also singular terms of a higher level - one will probably be able to say that the reference to abstract objects presupposes the reference to concrete objects - at least equiprimordial.
