Scientific Theory Research Interpretation Semantics - Metaphysics

Modern scientific knowledge has been regarded as the most universal and reliable knowledge. Generally speaking, the core of scientific knowledge is the theoretical one. The reason why scientific theoretical knowledge could be regarded as universal and reliable knowledge is that it is always trying to represent the physical world objectively, and the representation can be justified well. That means a general semantic analysis on scientific theories, including characterizations to their structural formalizations, must be an important philosophical thesis, which can construct some interpretation patterns of scientific theories. However, from the appearance of’the Received View’which is the first systematic philosophical conception of scientific theories, researches on scientific theories have usually engendered lots of problems and actually bogged down into some dense fogs. The fogs have two types. The first is some ideas that characterize scientific theories as some kinds of fitting to local empirical phenomena and evidences, also including fallibility conjectures based on the fitting. The other kind of fogs may assert that the reliability of scientific theoretical knowledge can only be justified by empirical results of scientific researches such as psychology, cognitive science and social science.All the causes of these two types of fogs can be summed up as the misconceiving of the isomorphism between structural formalizations of scientific theories and the semantic contents. Therefore, confusions between semantic phenomena and semantic basis could be apparent. Indeed, the structural relationship between the structural formalization of a scientific theory which represents physical world properly and the content of this structure should be isomorphism. However, isomorphism is only a necessary condition of proper representation, but not a sufficient one. Therefore, a proper semantics of scientific theories should present a sufficient and necessary condition of theoretical representation. The solution of this problem relies on an a priori question that how could isomorphism between scientific theoretical structure and content be possible. Isomorphism lacking of strict reviews on’How possible’a priori question is a kind of semantic phenomena, including metaphysical and epistemological judgments deriving from isomorphism. And the presumed condition to make semantic phenomena possible is the semantic basis. The semantic basis of scientific theories comprises truth itself which make all theoretical statements have a truth value, and senses of theoretical statements which make statements refer to its truth value. The basis of sense is calculative rules characterized by commutability and symmetry on theoretical concepts. Sense also shows metaphysical particularity which is universal and of necessity of laws of nature. Then, the whole research on interpretations of scientific theories goes through a semantic-metaphysical approach. This research also approaches to Frege’s philosophical project, and it may advance a new approach to attain the goal of Frege’s project.
