Predicating Subject

The "predicating subject" is a formal distinction introduced to differentiate two grammatically and logically separable positions within any act of predication. The "subject of the predicate" is the grammatical or logical subject about which something is said — the topic of the proposition. The "predicating subject," by contrast, is the agent or origin of the act of saying itself: the one who could, in principle, precede the proposition with "I say." This second-order position is what grounds predication as an act rather than merely a structure, and it is precisely this position that the clinical formula ça parle — "it speaks" — places in suspension. When Stein invokes ça parle, the predicating subject is not simply absent; rather, the question of its identity is formally bracketed, producing what is termed a second-degree predication in which speech occurs without a determinable agent of enunciation.

The theoretical force of this distinction lies in its clinical application: by suspending the predicating subject, the analytic situation is located at a fusional imaginary limit-state — a condition in which the boundary between self and other, speaker and spoken, collapses or becomes undecidable. This limit-state is proposed as structurally common to all transference-capable patients irrespective of their specific clinical structure (neurotic, psychotic, or perverse). The predicating subject is therefore not a phenomenological description of who speaks in analysis, but a formal marker of the minimal enunciative position that must be suspended or held open for transference — and thus analytic work — to become possible.

This concept appears once in jacques-lacan-seminar-13 (p. 100) and functions as a quasi-logical scaffolding for several of the seminar's clinical and structural concerns. Its most direct anchor is the concept of the Subject: by splitting the subject into the subject-of-the-predicate and the predicating subject, Stein sharpens the Lacanian insight that the subject of enunciation and the subject of the enunciated are never identical — the predicating subject names precisely the enunciating pole that classical grammar tends to conflate with its grammatical correlate. The suspension of the predicating subject in ça parle is thus a formal restatement of the split or barred subject ($) at the level of speech-acts.

The concept also sits in close proximity to Imaginary and Fusional Situation: the imaginary register, defined as the domain of the dyadic, specular, and narcissistic, is the register in which the boundary between predicating subject and subject-of-the-predicate dissolves — i.e., in which the question "who says?" cannot be stably assigned to one pole of the relation. This fusional imaginary limit-state is what enables Transference by making the patient's desire fungible with the analyst's position as Other. Finally, the connection to Clinical Structures is structural rather than differential: the predicating-subject suspension is proposed as a common ground that precedes the differentiation of neurosis, psychosis, and perversion, locating it at a more foundational logical level than the structural distinctions that define each clinical type. The concept thus functions as a specification and formal grounding of the more general notions of Subject, Imaginary, and Transference operative throughout the corpus.

the one who is at the origin or the one who is the agent of the predication … the one who could precede the proposition by an 'I say', let us call him the predicating subject.

The phrase "the one who could precede the proposition by an 'I say'" is theoretically loaded because it locates the predicating subject precisely at the level of enunciation — the "I say" that is structurally prior to any enunciated content — while the word "could" (not "does") immediately marks this position as virtual or suspendable, which is exactly what the clinical formula ça parle exploits by leaving the agent of predication indeterminate.
