Techject / Ecotechnics (Nancy)

Nancy's late philosophy-of-technology operates with two distinct-but-coordinated terms: techject (II §3 e raw 559) — neither object nor subject, the agent of intrinsically-technical relations — and ecotechnics (II §3 d raw 549) — the regime in which "the anthropological and physiological regime" of being-in-common-with-the-with is constitutively technical. Together they articulate the Nancean thesis: "Technological being-with is a being-with the 'with' itself" — there is no Mitsein without an intrinsically technical mit. The thesis follows from allonomy (technē as practical name of difference-to-self) and from vanishing-ontology (the real ↔ technical is the operational form of vanishing being). It refuses any ethics of good or bad uses of techniques in favor of a thinking of technics as such.

What the Concept Does

The conjunction techject + ecotechnics performs three argumentative tasks:

Generalizes Nancy's body / corpus / mêlée vocabulary into the technical: just as the corpus is body-as-collection-of-collections (see corpus-corporum) refusing the Leib/Körper distinction, the techject is artifact-as-relation refusing the object/subject distinction. "Technical objects and subjects — if it were not too laborious, one could name them 'techjects', neither objects nor subjects — are the aspects, segments, figures, and agents of our relations, relations that are as much intercosmic as interhuman" (II §3 e raw 559–560).
Re-grounds Heideggerian Mitsein as constitutively technical: Heidegger's Mitsein is existentialia of Dasein, primordially interhuman. Nancy's move: there is no Mitsein without an intrinsically technical mit. "There is therefore a 'with' — a mit and a Mitsein — that turns out to be intrinsically technical" (II §3 e raw 562). The wheel, the lever, the automobile, the city — all are techjects, and the Mitsein they enable is the only Mitsein there is.
Substitutes ecotechnics for ethics-of-technology: Nancy explicitly: "the thinking of 'technics' cannot consist in a reflection on the good or bad uses of techniques, as if we disposed of a horizon of reference in relation to which we could determine the 'good' and the 'bad'" (II §3 d). The replacement-vocabulary is ecotechnics: "technics — decidedly understood as the anthropological and physiological regime of what one could call an 'ecotechnics' — exposes the reality of sense as that of the communication and participation, the referral, the relation, and the sharing for which the physical dehiscence of the logos forms the 'metaphysical' propulsion."

Key Points

The techject coinage (II §3 e raw 559): explicit one-time use, in parenthesis ("if it were not too laborious"); Nancy himself flags it as somewhat labored but proposes it as the philosophical substitute for the object/subject pair. The techject is what each technical artifact is: not an object (it would be unmoved-by-relation) and not a subject (it would have agency-from-self).
Intercosmic and interhuman: "the conception, fabrication, and use of these vehicles fit within an ensemble itself made up of complex collective implications" (II §3 e raw 561). Technical relations are intercosmic (between things and material processes) and interhuman (between persons) at once; the techject names what enables this double-relation.
The city as paradigmatic techject: "The urban phenomenon alone gives a particularly striking image of this, because the city is at once itself a 'techject' and the site of an intensification and a growing complexity of indefinitely multiplied techniques" (II §3 e raw 561). The city is one techject; it is also the site where techjects multiply. The figure of the city absorbs the architectural / cybernetic / political / aesthetic registers into a single techject-figure.
The real ↔ technical operation (II §3 e raw 565): "The real is as technical as the technical is real." Vanishing ontology (II §3 e) and ecotechnics (II §3 d) are coordinated: the il y a of vanishing ontology is operationally the real-as-technical of ecotechnics.
The dehiscence of logos as metaphysical propulsion (II §3 d raw 549): "the physical dehiscence of the logos forms the 'metaphysical' propulsion" of ecotechnics. The voice/speech dehiscence (II §3 b–c, along the hyoid bone) is the bodily-symbolic anchor of the technical regime; the metaphysical in scare-quotes (because the meta- is no longer transcendent) names the propulsion — the forward motion — of ecotechnics, not its founding ground.
Sense as communication, not communicated (II §3 d raw 550–551): "It is instead a question of thinking and experiencing the intensity of a communicating (rather than communicated) sense in accordance with the non-immediacy and heterogeneity of senses, of their 'subjects', and of their 'channels'." Communication-as-active-verb (communicating-in-process) replaces communication-as-product (communicated-content). This is the sense-register of ecotechnics; cf. Nancy's lifelong sense/signification distinction.
The Coda of Ch II (raw 600–608): the appropriation of ends replaces appropriation of means (the latter is what communism sought). "The appropriation of ends can only consist in going beyond the very representation of 'ends'. In ceasing to want to define humanity, its sense and its destiny. In thinking beyond the possible." The result: "A finality without end that would not be aesthetic in the limited sense of the word, but would concern all forms of sensing and sensibility."

What It Rejects

Instrumentalism: technology as tool in the service of human ends. The techject is not a tool because there is no prior relation it could serve.
Substantialism: technology as substance (machines, devices, infrastructures) with its own essence. Ecotechnics is relation, not substance.
Ethical instrumentalism: the good-or-bad-uses framing. Nancy: "as if we disposed of a horizon of reference."
Heideggerian Gestell-as-foreclosure: Heidegger's Gestell (Ge-stell, en-framing) frames technology as the enframing-of-Being that occludes other-thinking. Nancy keeps the diagnostic but refuses the foreclosure-reading; ecotechnics is what we have and what we must think with, not what blocks thinking.
Marxist productive-forces / instruments-of-production framing (in the strict sense): the techject refuses the means-of-production / relations-of-production distinction because there is no prior relations into which means are inserted.
Mitsein-as-primarily-interhuman: technological Mitsein is intercosmic and interhuman at once.
Restoration of an authentic-pre-technical life: cf. I §5 critique of Hans Jonas's "authentic" — already refused at the allonomy level.

Stakes

For philosophy of technology: the late-Nancean alternative to Heidegger's Question Concerning Technology. Heidegger's Gestell is what we must think against; Nancy's ecotechnics is the regime we are already in. The diagnostic is similar (technology as the operative mode of late metaphysics) but the attitude is different.
For political philosophy: the appropriation of ends (Coda) reframes the communist tradition. Means of production (Marxist) and ends of production (Nancy) are not the same target. The political-form requires ceasing to define humanity.
For Mitsein-debate: Nancy's claim that Mitsein is technical repositions the entire debate. Heidegger's Mit- (in Mitsein) was assumed to be primarily-interhuman; Nancy's mit is primarily-relational (intercosmic and interhuman at once).
For sense-philosophy: communicating-rather-than-communicated sense is the operative form. Sense is active-verbal, not product-of-transmission.
For Anthropocene ethics: the fragile skin of the world (see fragile-skin-of-the-world) is the world-scale ecotechnical figure; the techject-relations are the world.
Confidence: medium-high. Techject is a one-occurrence coinage; ecotechnics is used multiple times across the Nancean corpus but only once explicitly in this book. Both names mark a namable late-Nancean philosophy-of-technology, even if the names are not yet stable.

Problem-Space

The concept addresses how to think technology after the closure of instrumentalism, substantialism, and Heideggerian enframing. The same problem-space is approached in:

Heidegger 1953, Die Frage nach der Technik — Gestell; Bestand (standing-reserve); Geviert (fourfold). Closest pre-Nancean formulation; Nancy keeps the diagnostic, refuses the foreclosure-reading.
Heidegger 1962, Zeit und Sein (Beilage) — brauchende Eignis; the Es gibt as Brauch-relation. The late Heideggerian recognition that giving is itself using; closer to Nancy.
Stiegler, Technics and Time — technology as the pharmakon (poison-remedy) of human cognition. Cousin: Stiegler's pharmacology has a therapeutic register Nancy lacks.
Hörl, Sacred Channels — Nancy wrote the preface to Hörl's book (Ch II §3 of Fragile Skin is the adapted preface); shared media-philosophical vocabulary.
Latour, We Have Never Been Modern; Reassembling the Social — nonhuman agency; actants; networks. Cousin: Latour's actor-network theory is sociological-empirical; Nancy's techject is philosophical-ontological.
Simondon, Du mode d'existence des objets techniques; L'individuation — technical individuation; transindividuation. Direct citation at VII fn 3 ("Simondon must clearly be mentioned here"); the transindividuation register is structurally close to techject-relations.
Yuk Hui, The Question Concerning Technology in China — cosmotechnics. Cousin: Hui's cosmotechnics is cultural-multiplicitous; Nancy's ecotechnics is structurally singular (one global ecotechnical regime, with no alternative cosmotechnics).
Nancy 1993, Sense of the World; 2002, Création du monde — earlier deployments of the écotechnie term; Fragile Skin is the late synthesis.

Connections

foundational for fragile-skin-of-the-world — the factorial-of-skins is the ecotechnical world-figure; every skin-encounter is techject-mediated.
requires allonomy — technē is "the practical or 'praxical' name of difference to self"; ecotechnics is the regime of operative allonomy.
requires vanishing-ontology — the real ↔ technical operation is the technological face of vanishing being.
foundational for singular-plural — the technical creation of the singular-plural world (VIII raw 1214) makes technology constitutive of singularity.
re-grounds mitsein (if such a page exists) — Mitsein as constitutively technical, not primarily interhuman.
contrasts with MP's écart — both think relation-without-substantial-units, but MP routes through bodily perception/flesh; Nancy through intercosmic-interhuman techjects.
contrasts with Heidegger's Gestell — same diagnostic of late-modernity-as-technology; different attitude (Nancy refuses foreclosure-reading).
cites Simondon (VII fn 3) — transindividuation as structural-philosophical predecessor.
has cross-tradition cousin Latour's actor-network — both refuse the human/nonhuman binary at the relational level.
develops Nancy's earlier écotechnie (Sense of the World, Creation of the World) — Fragile Skin II §3 is the late-period synthesis.
prefigured by techne-of-bodies — the 2000 vocabulary (Corpus, L'intrus) Derrida thematizes in On Touching; the early-period form of what ecotechnics names in late synthesis.
engaged at primary-source level by derrida-2000-on-touching-nancy §10 — Derrida reads Corpus and L'intrus on machine-bodies (corps-machine), prosthetics, transplantation, tele-sensible expropriations.

Open Questions

Is "techject" a coinage or a passing suggestion? Nancy himself flags it as "laborious" and offers it in parenthesis. A conservative reading: this is a gesture-toward-a-needed-name, not a settled concept. A constructive reading: the gesture is sufficient — the name is needed and works as named.
What is the relation between techject and quelconque (whateverness)? The quelconque (Nancy, BP 173–87) is indeterminate-but-concrete; the techject is neither-object-nor-subject. The two figures are structurally adjacent — both refuse object/subject distinction at the foundational level — but the wiki has them as separate concepts. See whateverness-quelconque and consider whether techject is the technical species of the quelconque genus.
Does ecotechnics extend to non-human beings? The text gestures at this (intercosmic-interhuman, II §3 e raw 560) but is mostly anthropological-physiological in its framing. The world-scale extension (VII's fragile skin) is the cosmological-form; whether techject-relations between non-human entities are ecotechnical in the strict sense is open.
What is the political-form of ecotechnics? The Coda gestures at "appropriation of ends" and "finality without end" but does not develop a political program. The closing image of the book ("hold firm to the shore", VIII) is the attentive form but is thin on practical-political content.

Derrida's 2000 reading of Nancy's Corpus (1992) and L'intrus (2000) anchors Nancy's technē of bodies / ecotechnics vocabulary at the earlier end of the chronology — twenty years before the Fragile Skin late synthesis. Derrida §10: "the project of a 'deconstruction of Christianity,' long announced or prepared; the attention paid to the 'technē of bodies' and ecotechnics that 'deconstruct the system of ends'" (p. 233). The techject coinage (2020) is Nancy's late systematization of what technē of bodies (2000) already named; see techne-of-bodies for the early-period attestation.
