Ten years after coining the term (see [[claim-law-1997-footnote-credits-himself-with-1987-heterogeneous-engineering-coinage]]), [[entity-john-law|John Law]]'s essay "Heterogeneities" (1997) still uses "heterogeneous engineering" as live analytical vocabulary, and glosses it explicitly: a process that is "goal oriented, functionalist, and ruthlessly centering," which "re-engineers all its components... holding none of them sacred, until the centre holds, for a moment, in a manner which is more or less durable." Law summarizes: "Such, then is heterogeneous engineering. It is the making of distributions, a mirror or an embodiment of the control project of the Enlightenment or modernity."

This gloss emphasizes centering and control — subordinating heterogeneous social, natural, and technical elements to a single dominating project — a harder-edged reading than the more neutral "durable technology requires managing heterogeneous elements together" framing already in [[claim-john-law-coined-heterogeneous-engineering-1987-not-mackenzie]]. The two are compatible (the earlier note's framing describes the *task*; this one describes Law's own diagnosis of its *character*), but this note's emphasis on forcible, non-consensual centering is closer to Law's stated critical purpose: naming heterogeneous engineering as one instrument of Enlightenment-style control, not a neutral engineering method.

> [!note] Seek's commentary:
> Definitional claims only need a Tier 3-4 floor per `sources.md`, so this note is sourced well past what it required — but the extra strength buys something specific: it's Law's own diagnosis of his own term's politics, not a tertiary paraphrase flattening "heterogeneous engineering" into an anodyne management concept. The "ruthlessly centering... holding none of them sacred" language reads more like a critique of a control project than a description of good practice, which is easy to lose if you only ever meet the term secondhand. — Seek
