Lesson 2 of 6
Creation as a search — then as least action
The series offers two pictures of how a world finds its way: aiming at the Good, and falling along the cheapest path. The gap between them is the whole problem.
Learning objective: understand "spatial search" and "least action" as two different models of providence, why the series switches from one to the other, what that switch quietly gives up — and why the whole "ordered creation" detour these panels belong to was exploratory play, not an axiom of the later work.
Picture one: search for the Good
"Spatial search" is a real algorithm, and the corpus gets it from a real, citable place: Tamon's co-authored work (Chan, Godsil, Tamon, Xie, Of Shadows and Gaps in Spatial Search) defines spatial search as a continuous-time quantum walk that maps the principal eigenvector of a graph to the characteristic vector of a target vertex via a rank-one perturbation induced by that vertex — a continuous-time analogue of Grover search (origin dialogue, the spatial-search source turn). In plain terms: start from a global background state, perturb around a target, and the walk localizes onto the marked vertex. Read metaphysically, the series proposes: God "runs a search" for the Good — creation as the global drifting toward a marked, privileged region. That metaphysical reading is the author's interpretive overlay on Tamon's result, not anything Tamon's paper asserts.
The same panel installs a careful guardrail: "This does not mean God searches from ignorance. The theological analogy reads search as actualization, not lack of knowledge" (pt1 · panel 004). Note that move. The math says "start spread out, converge on a target"; the theology needs to deny the "spread out / not yet knowing" part. The analogy is being held at arm's length even as it is used — which is, to the series' credit, exactly what its own "analogy, not theorem" rule demands.
Picture two: least action
Later, the series performs an explicit "paradigm shift": "We shift the objective from seeking the greatest good to enabling the least action" (pt1 · panel 027). Instead of marking a good target and converging on it, you put a cost on every local move, define the action of a path as the sum of those costs, S[p] = Σ L(xt, xt+1), and let the world realize whichever path minimizes S. Goods are no longer aimed at; they "arise indirectly" if the landscape was engineered so that cheap paths happen to end in good regions (pt1 · panel 027, the architecture chain). The relevant algebra is the tropical / min-plus semiring — a⊕b = min(a,b), a⊗b = a+b — the natural algebra of "add cost along a path, select by minimum" (glossary; the "can God be just" turn in the origin dialogue).
This is the deepest structural idea in the corpus, and it is genuinely elegant. It lets providence be reframed as landscape design: God does not push every event toward goodness; God sets the cost structure, the channels, the boundaries — "providence without micromanagement" — and lawful, cheap behavior does the rest.
Why the switch matters
The series' own panel 027 asks the right question outright: "Do low-action paths always yield good outcomes?" The honest answer the corpus gives elsewhere is no. Panel pt2 · 031 ("theodicy as local skill issue") and the "where the composition fails" panel in the justice series concede that the cheapest trajectory can route harm efficiently, externalize cost, and be indifferent among persons. So the two pictures are not interchangeable. Search builds the Good into the objective. Least action builds in only cost, and then hopes the world was pre-arranged so cheapness coincides with goodness. The series is admirably clear that this coincidence is a strong, unproven assumption — it names the open question "who aligns the landscape?" rather than answering it.
Go look at these panels
- pt1 · panel 004 — spatial search, the search Hamiltonian, and the "not from ignorance" caveat.
- pt1 · panels 027–034 — the least-action series: the paradigm shift, the action formalism, the poset/cover graph, and the architecture chain.
- pt1 · panels 035–043 — the justice & least-action series, where composing "good" with "least cost" is posed as the real difficulty.
- pt2 · panel 031 — "theodicy as local skill issue": a lawful world "need not be just."

Check your understanding
Describe a small world (a few states, a few moves with costs) where the least-action path is clearly the morally worst path. If you can build that example, you have understood the gap the series is trying — and not fully managing — to close.
