Michael Polanyi's preface to *The Logic of Liberty* (1951) grounds the whole
book's theory of liberty in the same "fiduciary" commitment-structure that
later became his tacit-knowledge epistemology:

> "I take more seriously here than was done in the past the fiduciary
> presuppositions of science; that is the fact that our discovery and
> acceptance of scientific knowledge is a commitment to certain beliefs which
> we hold, but which others may refuse to share."
> — Polanyi, *The Logic of Liberty* (1951), Preface, p. vi

Part I of the book ("The Example of Science") treats science itself as a
spontaneous order governed by professional opinion, consultation, and personal
judgment that resists exact formalization — the same machinery Polanyi later
systematized as tacit knowledge ("we know more than we can tell"). Struan
Jacobs's paper independently corroborates the continuity from Polanyi's own
side: Polanyi's retrospective in *The Tacit Dimension* (1967) states his ideas
"were first given a systematic form in *Science, Faith and Society* in 1946,"
where he **"considered science...as a variant of sensory perception"** (Jacobs
1997, p. 17, quoting *Tacit Dimension* p. ix) — placing the tacit-knowledge
line of thought in exactly the 1940s–50s work on science-as-spontaneous-order
that also produced the Mont Pelerin–era political writing.

This is the direct answer to the hook in
[[observation-michael-polanyi-person-bridges-three-vault-clusters-invisible-to-vault-bridge]]:
the political-economy work is not a "third, unconnected chapter." The
epistemology cluster the vault already holds — [[entity-michael-polanyi]],
[[claim-polanyis-paradox-tacit-tasks-resist-automation]],
[[claim-michael-polanyis-epistemology-influenced-dreyfus-critique-of-first-generation-ai]]
— and this 1951 political book are one continuous argument about knowing what
cannot be fully stated, applied first to scientific judgment and then to social
order. The disagreement with Hayek over ends
([[claim-polanyi-hayek-spontaneous-orders-differ-on-directedness-toward-ideal-ends]])
follows from exactly this fiduciary grounding.

> only pointed at freedom instead of at chemistry. Autor's automation paradox,
