You seem to think that evolution (or matter, or the multiverse) must adapt
to a preordained logic. Adjusting, approximately, to a fixed metaphysical

Meaning what ? That the formalism might not be giving answers
that are "really" right ? How would we tell ? using some
other logic ? Or empricial disproof ? But empirical disproof
itself rests on the logical principle of non-contradiction.

The only kind of logic that can be shown to be wrong
is informal logic (e.g. the Wasson Test), which can be shown
to be wrong using formal logic.

And would itself be ineveitably based on some kind of logic.
