論理 — the arcane logic of things half-understood
Every investigation begins with a single thread pulled from the fabric of what everyone else assumed was settled. Logic is not cold — it burns. The diagrams on the left were found pinned to a corkboard in an apartment in Kanda-Jinbocho, the bookseller's quarter, where the narrow streets are lined with volumes nobody remembers writing.
The connections are tentative. A circled node marked IF leads by a wavering line to THEN, but the conclusion — the therefore, the ∴ — sits isolated at the bottom, connected to everything and nothing.
cf. notebook entry 47: "the premises are sound but the room is dark"
What follows is not a proof but a process — the gathering of half-thoughts, crossed-out hypotheses, and diagrams drawn in haste by candlelight. Each spread of this document represents one night's work. Some contradict the others. That is the nature of investigation.
The page numbers refer to a manuscript that may or may not exist. —Ed.

The third notebook was water-damaged. What remains suggests a system of classification based on temperature rather than category — warm truths and cold truths, with the warm ones considered more reliable.
"The flame proves nothing except that the wick is willing."
ronri.xyz is an exercise in treating logic as craft rather than science — something practiced with ink-stained fingers by candlelight, where the process of reasoning is as important as its conclusions. Every page of this document was assembled in the manner of a zine: cut, pasted, annotated, and occasionally set on fire.
The word ronri (論理) carries the weight of rigorous deduction, but here it is employed in its more archaic sense — the pattern-finding of a mind working alone, late at night, surrounded by books it cannot quite read.
