Meta language/Tugendhat: typical truth condition of a predicative assertion: is true iff the singular term is an element of the class, for which the predicate stands - then comes the desscription of the object in the meta language - TugendhatVsMeta language: 1. relapse in the object theory - 2. one must understand what a class is - 3. one must understand the expression in another language - 4. predicate and singular term are not explained as complementary expressions.
TugendhatVsMeta language: presupposes that we understand meta language signs - otherwise we would not have gotten beyond the syntax - then ever higher orders needed - regress - Solution: pragmatics (VsCanap).
