Abstract

The concept of a presentation of a theory is often introduced in discussions of the "semantic view" of theories to characterize the way in which models for a theory are specified. Presentations are most often thought of as definitions of the kinds of systems represented in the models. It is argued that the concept of a presentation can be widened to permit consideration of the links between epistemologically motivated accounts of theory structure and some metaphysically motivated accounts of the growth of scientific knowledge. Conceptual maps are discussed as a possible elaboration of presentations which support Hull's metaphysical conception of theories as conceptual historical entities.
