    Idealization and Abstraction in Scientific Modeling.Demetris Portides - forthcoming - Synthese:1-23.
    I argue that we cannot adequately characterize idealization and abstraction and the distinction between the two on the grounds that they have distinct semantic properties. By doing so, on the one hand, we focus on the conceptual products of the two processes in making the distinction and we overlook the importance of the nature of the thought processes that underlie model-simplifying assumptions. On the other hand, we implicitly rely on a sense of abstraction as subtraction, which is unsuitable for explicating (...)

    Seeking Representations of Phenomena: Phenomenological Models.Demetris Portides - 2011 - Studies in History and Philosophy of Science Part A 42 (2):334-341.
    A distinction is made between theory-driven and phenomenological models. It is argued that phenomenological models are significant means by which theory is applied to phenomena. They act both as sources of knowledge of their target systems and are explanatory of the behaviors of the latter. A version of the shell-model of nuclear structure is analyzed and it is explained why such a model cannot be understood as being subsumed under the theory structure of Quantum Mechanics. Thus its representational capacity does (...)

  4. A Theory of Scientific Model Construction: The Conceptual Process of Abstraction and Concretisation. [REVIEW]Demetris P. Portides - 2005 - Foundations of Science 10 (1):67-88.
    The process of abstraction and concretisation is a label used for an explicative theory of scientific model-construction. In scientific theorising this process enters at various levels. We could identify two principal levels of abstraction that are useful to our understanding of theory-application. The first level is that of selecting a small number of variables and parameters abstracted from the universe of discourse and used to characterise the general laws of a theory. In classical mechanics, for example, we select position and (...)

  6. Scientific Models and the Semantic View of Scientific Theories.Demetris P. Portides - 2005 - Philosophy of Science 72 (5):1287-1298.
    I argue against the conception of scientific models advocated by the proponents of the Semantic View of scientific theories. Part of the paper is devoted to clarifying the important features of the scientific modeling view that the Semantic conception entails. The liquid drop model of nuclear structure is analyzed in conjunction with the particular auxiliary hypothesis that is the guiding force behind its construction and it is argued that it does not meet the necessary features to render it a model (...)

  12. Representation and Denotation in Scientific Modeling.Demetris Portides - 2018 - Proceedings of the XXIII World Congress of Philosophy 62:131-136.
    Nelson Goodman argued convincingly that in order to understand the representation relation one should dissociate it from the relation of resemblance because of the logical differences between the two concepts. Resemblance is reflexive and symmetric whereas representation is not. Furthermore, Goodman suggested that what lies at the core of representation is denotation. According to Goodman, if X represents Y then X must denote Y, but he recognized that by opting for an analysis of representation only based on this idea of (...)
