Nanopublication — Whether reality is at bottom mental: idealism's long metaphysical argument

Declined — no-purchase ^[1]

Propositional grid ^[2]

Read this grid. “Not evaluated” does not mean the source has nothing to say about that proposition. It means the reading did not instruct it. That is not a result, and it counts in no denominator. A silence, by contrast, is a finding: the reading touched the proposition without concluding, or noted its absence itself.

Not evaluated (37) — P1, P2, P3, P3a, P4, P5, P6, P7, P8, P9, P10, P11, P12, P13, P14, P14a, P14b, P15, P16, P16a, P17, P18, P18a, P19, P19a, P20, P21, P22, P23, P24, P25, P26, P27, P28, P29, P30, P31

Overall verdict: DECLINED:no-purchase — taxonomy of the August 2026 pass, predating the move to relational verdicts. Kept as metadata: the gap between the two forms is data, not residue. This reading’s judgement is in the grid above.

First pass — kept as written

Reading produced by the T50 RSS pass, before the boundary lens. It is reproduced UNCORRECTED. Keeping it is the point: without it, a changed title is just a changed title — with it, what the second pass refused becomes legible.

Title it carried : « Idealism's Ouverture: How Minds Shape Reception Across Centuries »

The idealist tradition — from Descartes through Kant to Hegel — is fundamentally a theory of the ouverture. It asks: what is the structure of mind that shapes how reality becomes knowable? The revision's attention to how idealism 'anticipated' and 'changed across centuries' reveals the ricochet effect in intellectual history: each generation receives the idealist wave through its own epistemic aperture, refracts it, and produces a new idealism that the previous generation did not intend. Kant's transcendental idealism was not what Descartes emitted — it is what Descartes's emission became when it passed through Kant's particular ouverture (Enlightenment mathematics, Newtonian physics, critical philosophy). The entry itself, revised in 2026, is an instance of this: the Stanford Encyclopedia receives idealism anew, and the act of revision is the ricochet — the intentional invariant (what idealism structurally IS) generates new diffractions in contemporary philosophy. This is not metaphorical: idealism as a codex (a system of constraints on how mind and world relate) produces different creations in different historical ouvertures.
