    Many models in science are both logical and representational models simultaneously.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Newton's model of planetary motion consists of two homogeneous perfect spheres in otherwise empty space that attract each other gravitationally.
      ?

      Think about whether this reason is strong or weak

    • 2.Newton's model is a logical model because it makes the axioms of Newtonian mechanics true when those axioms are interpreted as referring to the model.
      ?

      Think about whether this reason is strong or weak

    • 3.Newton's model is a representational model because it represents the real sun and earth.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Logical models are defined by satisfaction relations between sentences and set-theoretic structures, requiring no intentional representational relation.
      ?

      Think about whether this reason is strong or weak

    • 2.Representational models require an intentional 'stand for' relation grounded in use, purpose, or resemblance, which is absent from purely formal satisfaction.
      ?

      Think about whether this reason is strong or weak

    • 3.Because the two relations are constitutively distinct, no single object can instantiate both simultaneously without equivocating on 'model'.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Newton's two-sphere construction is a fictional entity that fails to denote any real-world system, as Cartwright argues idealized models are not descriptions of reality.
      ?

      Think about whether this reason is strong or weak

    • 2.A structure that misrepresents its target by stipulating homogeneous perfect spheres succeeds as a logical model precisely by abandoning representational fidelity.
      ?

      Think about whether this reason is strong or weak

    • 3.Therefore the Newton example illustrates a trade-off between logical and representational adequacy, not their simultaneous achievement.
      ?

      Think about whether this reason is strong or weak

    It is important to keep the notions of a logical and a representational model separate (Thomson-Jones 2006): these are distinct concepts. Something can be a logical model without being a representational model, and vice versa. This, however, does not mean that something cannot be a model in both senses at once. In fact, as Hesse (1967) points out, many models in science are both logical and representational models. Newton’s model of planetary motion is a case in point: the model, consisting of t
