    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Rigid rods and ideal clocks are relativistically ill-defined probative systems.
      ?

      Think about whether this reason is strong or weak

    • 2.Only well-defined probative systems are suitable for determining the inherent structures of spacetime.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Rigid rods and clocks, while not fundamental, serve as operationally indispensable epistemic bridges between abstract spacetime structure and empirical measurement.
      ?

      Think about whether this reason is strong or weak

    • 2.A probative system need not be relativistically fundamental to be suitable for determining spacetime structure, only reliable and systematically correctable.
      ?

      Think about whether this reason is strong or weak

    • 3.Reichenbach and Bridgman's operationalist tradition demonstrates that physical coordinative definitions using rods and clocks successfully ground metrical spacetime relations in practice.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Brown and Pooley's dynamical approach establishes that rods and clocks comportment is explained by Lorentz-covariant dynamical laws, making them legitimate trackers of spacetime geometry.
      ?

      Think about whether this reason is strong or weak

    • 2.If the behavior of rods and clocks is fully governed by relativistically well-formed laws, the ill-definedness objection conflates the instrument with the underlying physical process it instantiates.
      ?

      Think about whether this reason is strong or weak

    It should be noted, however, that Weyl’s defence of his theory implicitly addresses an important methodological consideration concerning the relation between theory and evidence. As Pauli puts it above, according to Weyl “the metric field must not be defined by means of information taken from these measuring instruments [rigid rods and ideal clocks]”. That is, Weyl rejects Einstein’s operational standpoint which gives operational significance to the metric field in terms of the observable b
