In Chapter 7 ("The Role of the Body in Intelligent Behavior") of *What
Computers Can't Do* (1972), while arguing that skilled human tool-use
cannot be reduced to a computer's rule-governed manipulation of objective
spatial coordinates, [[entity-hubert-dreyfus|Hubert Dreyfus]] writes:
"Heidegger, Merleau-Ponty, and Michael Polanyi have each devoted a great
deal of thought to this question." He then quotes
[[entity-michael-polanyi|Michael Polanyi]] directly — "As Polanyi puts it"
— on tools becoming "part of ourselves, the operating persons," citing
*Personal Knowledge* (1964), p. 59 (Chapter 7, note 28). Two pages later,
extending the same argument to language, Dreyfus quotes Polanyi a second
time, on learning to "interiorise" a tool or a probe or language itself,
citing "The Logic of Tacit Inference" in *Knowing and Being* (1969), p. 148
(note 32).

Both citations sit inside the chapter making Dreyfus's positive,
alternative case for embodied skill against the assumptions of 1960s
symbolic AI research — the same target as
[[claim-dreyfus-critique-targeted-symbolic-ai-not-neural-nets]]. Polanyi is
not a passing namedrop but part of the argumentative machinery of the
critique itself, cited from two separate Polanyi works and named alongside
Heidegger and Merleau-Ponty as one of three thinkers Dreyfus draws on for
this specific point. This confirms, for the specific book the claim is
actually about, the influence-line that
[[claim-michael-polanyis-epistemology-influenced-dreyfus-critique-of-first-generation-ai]]
previously held at seedling on a Tier 4 Wikipedia sentence alone. See also
[[claim-dreyfus-critical-of-polanyi-in-same-1972-passage]] for how Dreyfus's
engagement with this material is not simple endorsement, and
[[claim-polanyi-nearly-absent-from-dreyfus-taylor-2015-retrieving-realism]]
for a complication to the influence's durability across Dreyfus's career.
