This wasn't metaphorical decoration—Bush genuinely conceived the memex as a cognitive partner, something that would participate in thinking rather than merely supporting it mechanically. The language interface achieves this partnership: it holds incomplete ideas, interprets ambiguous specifications, generates examples that clarify thinking, and responds to the user's associative leaps with relevant continuations.
