Dimension-by-Dimension Evidence

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

Time

Arthur Norman Prior

Substantival but only the present is real — past events have happened but do not now exist; future events will happen but do not yet exist. Non-deterministic — the future is genuinely open.

Space

Arthur Norman Prior

Conventional modern.

Matter

Arthur Norman Prior

Conventional modern; only present matter exists.

Observer

Arthur Norman Prior

A single embodied person, present-tense throughout. Personal metaphysical agency: a Presbyterian theism that frames Prior's presentism with the conviction that genuine moral and religious decision requires a real open future.

Energy

Arthur Norman Prior

Conventional modern.

Information

Arthur Norman Prior

Conserved at both scales — but the conservation is presentist, holding moment by moment rather than across an eternally existing block.

Internal Tensions

Where each persona's working synthesis strains against itself.

Arthur Norman Prior

Prior's presentism strains against twentieth-century special relativity, which makes simultaneity frame-dependent. Subsequent presentists (Dean Zimmerman, John Bigelow) have worked on reconciliations; the tension between presentism and relativity remains live.
