Brooks's 1986 predecessor memo to "Intelligence Without Representation" cites Dreyfus twice by name, in a two-sentence opening frame that concedes his premise and disputes only achievability

"Achieving Artificial Intelligence through Building Robots" (A.I. Memo 899, MIT AI Laboratory, May 1986) is Rodney Brooks's own predecessor draft of "Intelligence Without Representation," the paper the vault already confirmed carries no Dreyfus citation in its 1991 published form (claim-brooks-1991-does-not-cite-dreyfus). The 1986 memo does cite him. Its opening paragraph pair names Dreyfus and states the premise that human-level intelligence requires "the totality of practices which make up the human way of being in the world" — a premise the memo concedes, going on to dispute only achievability and means ("Unlike Dreyfus however, we conclude that artificially intelligent behavior is achievable with computers without the aid of holograms, resonance, or other holistic techniques"). The memo's body (three arguments from evolution, abstraction, and epicycles) never returns to Dreyfus by name; see claim-brooks-1986-memo-dreyfus-engagement-concedes-premise-disputes-achievability for the full-text read this rests on. The reference list carries two entries: Dreyfus's What Computers Can't Do (1972) and "Why Computers May Never Think Like People" (Hubert and Stuart Dreyfus, Technology Review, January 1986).

This is a documented, primary-source, on-the-record engagement — Brooks naming Dreyfus, citing two of his works, and building his own project explicitly against Dreyfus's position — that predates and complicates the "our work was not so inspired... purely engineering considerations" disclaimer of the published 1991 paper (claim-brooks-1991-disclaims-heideggerian-inspiration). The disclaimer is true of the published text; it is not true of the argument's origin. It is one of three episodes (with claim-brooks-dropped-dreyfus-citation-after-reviewer-criticism and claim-brooks-2002-book-credits-dreyfus-per-dreyfus-2007-quote) behind the wider synthesis at claim-brooks-dreyfus-engagement-outside-iwr-runs-toward-rebuttal, and it answers question-brooks-dreyfus-secondary-literature-reception-lineage.

Correction history.

• 2026-10-04 — This note originally said the memo "frames its entire technical argument as an answer to [Dreyfus's] thesis." A full twelve-page read of the same primary (the 2026-09-26 recovered capture) found the string "Dreyfus" occurs only in the opening paragraph pair and the reference list; the three body arguments (evolution, abstraction, epicycles) never return to him, and the opening frame itself concedes his premise and disputes only achievability. Title and body corrected accordingly.
