Demotivation

In Boothby's reading of Lacan, "demotivation" designates the semiotic-structural operation by which the sign is prised apart from the image — the movement by which an icon or motivated sign (where signifier resembles or is "glued to" its referent) gives way to an arbitrary, differential signifier fully installed in the symbolic order. In Lacanian terms, this is the engine of symbolic castration: the cut that separates the imaginary dyadic bond (mother–child, image–referent, m–i axis of Schema R) from the symbolically mediated axis (I–M, the axis of the Ego Ideal and the Name-of-the-Father). The opening produced by demotivation is nothing other than the space of the Real — das Ding — the void that persists once the imaginary fusion of sign and image has been dissolved and no symbolic substitution can fully close the gap. Demotivation is therefore not merely a linguistic event but an ontological one: it installs lack at the heart of the subject's relation to the Other.

The concept is mobilized specifically to contrast Schema L with Schema R. Schema L maps the neurotic/analytic situation, where the imaginary axis (ego ↔ specular other) interferes with and covers over the symbolic axis (subject ↔ big Other). Schema R expands this picture to include the full Oedipal structure, and it is demotivation — the separation of sign from image enacted by the paternal function — that "opens the space" between the two diagonal axes, making the fuller schema legible. Without demotivation, the subject would remain captive to imaginary motivation (the seamless, narcissistic bond of image and meaning); with it, the subject enters the symbolic order proper, at the cost of an irreducible remainder: the Real opened between the two axes.

Within the source richard-boothby-freud-as-philosopher-metapsychology-after-lacan-routledge-2001, this concept appears at p. 271 as part of Boothby's sustained project of reading Lacan's schemas through the optics of semiotics and gestalt psychology. Demotivation is introduced precisely to name what Schema L cannot fully show: the passage from imaginary capture to symbolic mediation. Schema L (cross-ref'd) maps the interference of the ego–other (a–a') axis across the subject–Other (S–A) axis; demotivation is the process that structurally produces that very interference by differentiating the two. Schema R then diagrams the result: a space carved out between the imaginary and symbolic diagonals that Boothby identifies with the Real and, implicitly, with das Ding (cross-ref'd) — the excluded interior left by the sign's separation from the image.

The concept therefore sits at the junction of several cross-ref'd canonicals. It operationalizes the entry into the Symbolic order (Identification, Ego Ideal, Name-of-the-Father) by specifying the mechanism — semiotic demotivation — through which imaginary Narcissism (cross-ref'd as Narcissism and the Imaginary) is interrupted and the Oedipus Complex (cross-ref'd) becomes structurally effective. It is an extension and specification of the Lacanian account of symbolic castration, translating that account into the vocabulary of semiotics (Saussurean arbitrariness of the sign) in order to give Schema R a more fine-grained, semiotic reading than Lacan's own presentation supplies.

The process that opens the space between the two diagonal axes of the Schema L is the movement by which the sign is differentiated from the image, the movement semioticians call 'demotivation.'

The phrase "opens the space between the two diagonal axes" is theoretically loaded because it identifies demotivation as a topological operation — not merely a linguistic shift — that produces the Real as a gap interior to the schema itself; and the gloss "the movement by which the sign is differentiated from the image" explicitly anchors symbolic castration in semiotic arbitrariness, making the Saussurean cut between signifier and referent the very mechanism of the Oedipal passage from imaginary to symbolic.
