Dimension-by-Dimension Evidence

What each persona's writings reveal about their stance on each of the six dimensions.

Time

Pierre-Simon Laplace

Substantival, infinite, continuous, deterministic — the Newtonian-Laplacian backbone.

Space

Pierre-Simon Laplace

Newtonian: substantival, infinite, flat.

Matter

Pierre-Simon Laplace

Substantival, conserved, three-dimensional, local.

Observer

Pierre-Simon Laplace

A single embodied observer in a fully deterministic cosmos — the demon is an idealisation of what any sufficiently powerful observer could in principle know. Metaphysical agency: None.

Energy

Pierre-Simon Laplace

Conventional Newtonian.

Information

Pierre-Simon Laplace

Conserved at the cosmic scale by the deterministic laws (the demon's premise). Personal-identity non-conserved.

Internal Tensions

Where each persona's working synthesis strains against itself.

Pierre-Simon Laplace

Laplace's demon survived as a philosophical thought experiment but was undermined empirically by twentieth-century quantum mechanics and chaos theory. The 1814 essay's confident assertion of universal determinism reads now as a historical artefact of pre-quantum physics, though compatibilist debates about agency continue to invoke its framework.
