Philosophy Lexicon of Arguments

 
Under-determination, philosophy: contrary to e.g. geometric figures, no everyday object is fully described. An object is under-determined, if not all features belonging to its concept can be assigned with a value. The under-determinateness of theories is the problem that, even if an object is fully described in the framework of a theory, various other, non-equivalent theories can still apply to it. See also determinateness, uncertainty of translation, Gavagai, definition, criteria, certainty, quantum mechanics.

Underdetermination/Empiricism/Quine: also through unmonitored data.

Lauener XI 119
Underdetermination/Identity of theories/Quine/Lauener: theories: can be logically incompatible and empirically equivalent - E.g. interchanging -electron/molecule-: makes true sentences false - "since the change is purely terminological, you can say that both versions express the same theory -" so they are empirically equivalent -" however, the predicates can be reconstructed in a way that the theories also become logically equivalent - E.g. empirically equivalent: Theory a) space infinite -" b) finite, objects shrink with distance from the center -" Again, the predicates can be rephrased in such a way that the theories are logically equivalent -" underdetermination: In order to prove them, it would have to have an influence on the empirical content -" Quine: almost impossible to find an example.

Lauener XI 120
Underdetermination/Quine/Lauener: there are rivals to every infinite theory that are equivalent empirically, but not logically, and that cannot be made logically equivalent by reconstructing the predicates.

Stroud I 217
Underdetermination/Theory/Theoretical terms/Entities/Quine/Stroud: the truths that the scientist introduces e.g. about molecules are not sufficiently determined by all the truths that he knows or can ever know about the normal objects -" (s) there could be several possible theories which imply the same set of truths about the normal objects, but differ in terms of the theoretical ones -" theoretical entities do not follow from the truths about normal things -" Quine/Stroud: for him, normal objects are also just hypotheses -" this is how all theories go beyond data -" underdetermination: also remains, if we included all past and future nervous stimuli of all people.

Problem: even true sentences go beyond the data, are projections - therefore they cannot be known.
