Bas van Fraassen on Models - Dictionary of Arguments
I 47 Model/Fraassen: represents the worlds which are allowed by the theory. Unintended models: e.g. the theory that the center of the solar system may have any constant speed allows different speeds (> class of models) and something else than motions too! - So an empirically adequate theory can go beyond the data. - ((s) > Empirical underdetermination by the data: >Underdetermination/Quine. Problem: then you can still believe that any theory of a family of theories is wrong - and therefore their common part is wrong! Common part: may be paraphrased as "one of the models of the theories represents the world correctly" - ((s) and this may be wrong). Common part: is often not empirically important. >Relevance._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
