    A purely formal analogy with no physical significance cannot support a plausible analogical inference in physics.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Plausible analogical inference requires that the shared structural features carry some physical meaning.
      ?

      Think about whether this reason is strong or weak

    • 2.A purely formal analogy is founded only on mathematical similarities with no known physical basis.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Historical cases show purely formal analogies have generated empirically successful predictions before physical meaning was established.
      ?

      Think about whether this reason is strong or weak

    • 2.Dirac's use of mathematical symmetry in the Dirac equation predicted antimatter before any physical interpretation of negative-energy solutions existed.
      ?

      Think about whether this reason is strong or weak

    • 3.If a formally grounded inference can reliably track physical reality prior to interpretation, formal analogy alone can support plausible inference.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Wigner's 'unreasonable effectiveness of mathematics' suggests formal structure and physical significance are not cleanly separable in advance.
      ?

      Think about whether this reason is strong or weak

    • 2.The distinction between 'purely formal' and 'physically significant' analogy may be epistemic rather than ontological, reflecting current ignorance rather than absence of physical basis.
      ?

      Think about whether this reason is strong or weak

    Analogical arguments support the hypothesis that in each of these cultures, rock art symbolizes hallucinogenic experiences. Currie examines criteria that focus on assumptions about stability of cultural traits and environment-culture relationships. Currie (2016, 2018) and Wylie (Wylie and Chapman 2016) also stress the importance of robustness reasoning that combines analogical arguments of moderate strength with other forms of evidence to yield strong conclusions. Practice-based approaches can
