Dimension-by-Dimension Evidence

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

Standard physical time within each world; possible-worlds framework treats time-as-it-could-have-been alongside time-as-it-is.

Space

Saul Kripke

Standard substantival space.

Matter

Saul Kripke

Standard substantival matter with essential properties.

Observer

Saul Kripke

Plural finite reasoners with mediated access to modal and natural-kind truths. No metaphysical agency.

Energy

Saul Kripke

Standard physics.

Information

Saul Kripke

Information conserved at the world-scale; personal soul not part of the framework.

Internal Tensions

Where each persona's working synthesis strains against itself.

Saul Kripke

Kripke's necessity-of-origin and natural-kind essentialism have been attacked from anti-essentialist quarters (Mellor, Bird) and defended by mainstream analytic metaphysicians. The Kripkenstein reading of Wittgenstein has been disputed (Baker and Hacker, McDowell) as more about Kripke than about Wittgenstein. Kripke published little for the four decades after Naming and Necessity, leaving major work in private circulation; the Kripke Center is gradually releasing it.
