# Hierarchy changes with the projection

Can ontology, knowledge, and mind be represented as different projections without privileging one as the universal foundation?

The proposal treats apparent hierarchies as dependent on where one looks from. Reversing the explanatory direction may reveal another legitimate projection rather than a uniquely fundamental level.

Status: open problem. Formulation and comparisons: reconstruction. Development: active.

## Alternative representations

### Directed explanatory order

Affords: States a local direction of explanation.

Limits or losses: Can conceal the conditions under which direction reverses.

### Several overlapping projections

Affords: Retains competing local explanatory orders.

Limits or losses: Does not by itself prove consistency or equivalence among them.

## Tension

Permitting multiple perspectives is different from proving that all descriptions can hold together.

## Challenge

Which relation survives a change of perspective, and which incompatible predictions would separate the projections?

This challenge is an editorial prompt, not a claim that the evidence already resolved it.

## Proposed next move

Construct a small shared example with two reversed explanatory orders and record exactly what each preserves.

Status: new model-proposed experiment or extension; not a reported result.

## Related problems

- [One structure, several renderings](structure-across-renderings.md) — reappears with a changed question (retrospective_connection). Earlier renderings preserve or rearrange relations; the later proposal questions whether any one hierarchy has absolute priority. This is a retrospective route, not a claim that the later theory was already present.

## Evidence anchors

- basis-viewpoint-dependent-hierarchy: Ontology, knowledge, and mind are proposed as products of related projections. The explanatory hierarchy is said to change with the viewpoint: mind shaping existence and existence shaping mind are both entertained, and indeterminacy need not remain the privileged foundation. [Editorial paraphrase; presence of a proposal does not verify its truth.]

Root evidence and private recovery mappings are not part of this public release.
