    It is not the case that Poincaré demonstrated that geometry is conventional: we can always reinterpret physical facts by adopting a different geometry paired with different physical laws.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Not all geometric descriptions are equally convenient or predictively powerful; one geometry+laws pair typically outperforms alternatives, suggesting one tracks reality better.
      ?

      Think about whether this reason is strong or weak

    • 2.Saying geometry is purely conventional conflates the choice of *description* with the choice of *what is being described*—the underlying space has determinate structure.
      ?

      Think about whether this reason is strong or weak

    • 3.If any geometry-plus-physics pairing works equally well, empirical science becomes impossible; we need constraints on what counts as a legitimate alternative interpretation.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Physical observations underdetermine geometry: identical empirical data fits Euclidean geometry with one force law or non-Euclidean geometry with another.
      ?

      Think about whether this reason is strong or weak

    • 2.Conventions about coordinate systems and measurement standards are human choices that don't correspond to mind-independent geometric facts about space itself.
      ?

      Think about whether this reason is strong or weak

    • 3.General relativity shows we can describe the same spacetime using infinitely many coordinate systems, suggesting geometry is a descriptive tool, not a discovery.
      ?

      Think about whether this reason is strong or weak
