Ontological Exposures in Physics, Part 3 Exposure of Idealisation — When Convenience Becomes Reality

Physics frequently relies on idealised models: frictionless planes, point particles, perfect vacuums, and perfectly isolated systems. These simplifications are pragmatic tools, yet they are often implicitly treated as ontological realities.

This is the distortion: methodological convenience is mistaken for the nature of existence itself.


The Physics Move

  • Classical mechanics assumes frictionless surfaces and massless pulleys to simplify calculations.

  • Quantum models often rely on isolated systems or idealised potentials that cannot exist in reality.

  • Cosmological models employ perfect homogeneity or isotropy, smoothing over the complexity of actual structure.


Why This Overextends Ontology

Idealisation cannot capture actuality, yet treating it as if it does:

  • Suggests the world behaves like the model, rather than the model approximating the world.

  • Conceals relational complexity by substituting a simplified scenario for real interactions.

  • Reinforces the illusion that abstraction or convenience reflects reality directly.

The distortion lies in reifying simplification: the approximated becomes mistaken for the actual.


The Relational Reframing

From a relational standpoint:

  • Friction, discreteness, entanglement, and environmental interactions are features of relational actualisation, not violations of idealised models.

  • Idealised constructs are epistemic tools for calculation and intuition; their “existence” is symbolic, not ontological.

  • Recognising idealisation as methodological scaffolding preserves clarity about how relational dynamics actually unfold.

Thus, idealisation is intelligible — but only as a pragmatic simplification, not a constituent of reality.
