Temporal Determination
ELI5
When we experience one thing causing another, Kant says our mind is doing the work of locking each event into its proper place in the timeline according to a rule—without that mental work, there would be no difference between "A happened before B" and just a jumble of impressions with no objective order.
Definition
Temporal Determination, as articulated in the Kantian critical framework, names the transcendental operation by which the pure concept of causality (as one of the understanding's categories) is applied to the temporal manifold of intuition so as to constitute the objective ordering of phenomena. It is not a merely empirical observation that events follow one another; rather, the understanding's schematization of causality is what first makes it possible for any phenomenon to have a determinate, rule-governed position in the succession of time. Without this operation, appearances would remain a formless flux, incapable of cohering into the representation of an object. The principle of causality, on this reading, is the condition of possibility for objective empirical experience precisely because it assigns to each event its place in the temporal series a priori—prior to and independently of the content of any particular experience.
This concept belongs to Kant's "Second Analogy of Experience" and is a specification of what Kant calls the Analogies in general: the understanding does not generate time itself, but it legislates the rule by which appearances are ordered within time. Temporal Determination thus designates the synthetic a priori act by which a consequent is bound to its antecedent not merely as successive in subjective perception but as necessarily following from it according to a universal rule. Without this schematized determination, time—which as the form of inner sense is already a unified, continuous whole—could not be differentiated into an objective series of before and after at all. Causal ordering is therefore not projected onto an already-ordered time but is precisely what renders time objectively ordered for experience.
Place in the corpus
Within kant-immanuel-critique-of-pure-reason, Temporal Determination lives at the intersection of the categories of the Understanding (specifically Causality and Substance) and the problem of how pure concepts can be applied to the sensible manifold. It is a specification—indeed, the most precise formulation—of Causal Necessity as a transcendental rather than merely empirical principle: where causal necessity names the modal force binding antecedent to consequent, Temporal Determination names the positive, constructive work this binding does on the temporal field, giving each phenomenon its objective place. It thus also relates to Substance (which grounds the permanence of the substratum through time) and to Judgment (which, for Kant, is the faculty of subsumption under rules—here the causal rule is the rule being applied). Understanding, as the faculty of rules, is the agent of Temporal Determination.
In relation to the other cross-referenced concepts, Temporal Determination stands in revealing contrast to the Lacanian/Freudian frames in which Consciousness, Reality, Moment, and Repetition are elaborated. Where Kant's account grounds objective temporal order in the constitutive activity of an impersonal understanding, the Lacanian corpus—as synthesized for Consciousness and Reality—insists that the subject's temporal experience is structured by the unconscious and by signifying repetition rather than by any transparent cognitive act. The Lacanian "moment" and "repetition" are never simply causal-sequential in Kant's sense; they carry the weight of the subject's constitutive division and the deferred action (Nachträglichkeit) of the unconscious. Temporal Determination as a Kantian concept therefore marks a kind of limit-point or theoretical contrast for the Lacanian corpus: it represents the transcendental-idealist attempt to secure objective temporal order that Lacan's decentring of consciousness systematically displaces and complicates.
Key formulations
Critique of Pure Reason (page unknown)
it assigns to each phenomenon, as a consequence, a place in relation to preceding phenomena, determined a priori in time, without which it could not harmonize with time itself, which determines a place a priori to all its parts.
The phrase "determined a priori in time" is theoretically loaded because it captures the transcendental paradox at the heart of Temporal Determination: time, as the form of inner sense, is already a unified whole that "determines a place a priori to all its parts," yet that universal temporal order only becomes objective—only becomes the representation of an object rather than a subjective flow—when the understanding's causal rule "assigns" each phenomenon its specific, necessary place within it. The quote thus condenses both the receptive (time as pre-given form) and the spontaneous (the understanding's a priori assignment) poles of Kant's critical philosophy into a single operation.

Theoretical move: Kant argues that the principle of causality—that every event necessarily follows from a preceding state according to a rule—is not merely a feature of subjective apprehension but is the very condition of the possibility of objective empirical experience, with the understanding's application of causal order to phenomena being what first constitutes the representation of an object in time.
