The Nexus of Principles and Models in the Semantic View of Scientific Theories

Abstract

This paper considers Ronald Giere's Model-Based view of theories (MOT). Giere's propositions and theories are examined in terms of the author's own conceptualisation of MOT. This paper conceptualises the nexus between principles and representational models. It emphasises that the dynamics, respectively sequence, of scientific theories, could be based on this nexus. Summary: 1) The basic elements of theory are models serving as vehicles of principles. 2) Models are decisive in constructing theory. 3) The articula- tion of principles (in models) brings new knowledge that does not inhere in the principles themselves. 4) The acceptance of principles depends on the acceptance of a commensurate set of models. 5) New theories emerge when the set of models convince the scientific community that this set supports the new principles.
