Lure

The "lure" names the structural susceptibility of the libidinal subject to being captured by an image or semblance rather than by any real object or partner. Lacan grounds this concept in ethological evidence—Lorenz and Tinbergen's releasing mechanisms—where an animal's innate response fires not toward the actual organism but toward a specific imaginary trigger (a colour, a shape, a display). This demonstrates that the drive is organised around the Imaginary register: what the drive "aims at" is an imago, a screen, a mask—and this is constitutively a lure, since the image is not the thing. The lure is therefore not a contingent error or illusion that could in principle be corrected; it is the structural condition under which the drive operates. Sexual behaviour is identified as especially prone to it because the scopic and libidinal circuits are most thoroughly organised around the specular image.

In Seminar XI, the concept is extended from ethology to the human subject's relation to the gaze. Mimicry—the animal's use of patterns, masks, and displays—is the prototypical case of the lure operating at the level of semblance: the organism projects an image that both conceals and reveals, placing something between itself and the gaze of the predator or rival. What distinguishes the human subject, crucially, is not immunity to the lure but the capacity to isolate and play with the screen, to use the mask reflexively rather than being wholly captured in it. Nevertheless, the lure retains an "essential function": it is not merely a theoretical curiosity but something that "seizes us at the very level of clinical experience," meaning psychoanalytic practice itself encounters the lure as operative—in transference, in symptoms, in desire's perpetual attachment to semblances.

The concept of the lure appears across two seminars—jacques-lacan-seminar-1 (p. 127) and jacques-lacan-seminar-11 / jacques-lacan-seminar-11-1 (p. 122)—marking it as a durable, if concentrated, thread in Lacan's teaching. In Seminar I it functions primarily to anchor the Imaginary register: if the drive is oriented by image rather than real object, then the entire domain of libidinal life is shown to be structured by specular captivation, the "hall of mirrors" that the Imaginary definition identifies as constitutive of the ego and its formations. The lure is thus the operative mechanism that makes the Imaginary a register of capture—it is how subjects get caught in and by images.

By Seminar XI, the concept migrates into the analysis of the Gaze and the Scopic Drive. Here the lure is no longer merely the trigger of a fixed instinctual response but the very logic of mimicry and the screen: semblance (appearing as something one is not, or displaying a mask) is the lure's form at the level of visibility, working precisely at the point where the gaze, as objet petit a, irradiates the visual field. The Scopic Drive's reflexive circuit—"making oneself seen"—is itself a deployment of the lure: one presents an image to the Other's gaze. This also connects the lure to Desire and the Subject: since desire is structured around the object-cause (objet a) rather than any positive object, the lure is desire's natural medium—what desire encounters is always a semblance standing in for the constitutively absent real object. The lure is thus an extension and specification of the Imaginary, applied to show how the drive's Imaginary orientation becomes operative within the scopic field and within clinical experience.

The lure plays an essential function therefore. It is not something else that seizes us at the very level of clinical experience.

The phrase "essential function" refuses to relegate the lure to error or illusion—it is structurally necessary, not accidental. "Seizes us at the very level of clinical experience" is equally loaded: "seizes" (captures, grips) imports the language of imaginary captivation, while grounding the claim not in biology or theory alone but in the analytic clinic itself, asserting that the lure is a live operative force that the practitioner encounters directly.
