The extended present: SMM/DTT and Husserl’s retention and protention

A melody is heard as an unfolding unity, not as disconnected acoustic instants. Husserl’s distinction between retention, current impression and protention gives SMM/DTT a precise phenomenological comparison for temporal completion. The relation becomes stronger when these intentional structures are distinguished from stored data, hidden physical clocks and the six nested levels of generation.

01Three aspects of temporal appearance

Husserl’s analysis distinguishes the current phase of experience from its retention of the just-elapsed and its orientation toward what is coming. Retention is not simply deliberate recollection of a past event, and protention is not necessarily a conscious forecast. They describe the temporal articulation through which an event appears as unfolding. This is a phenomenological account: it examines the structure of experience rather than assigning three independent physical times. SMM/DTT can use it to sharpen what an observer’s completed present would need to contain. [1]

02What the SMM/DTT distinction contributes

SMM begins with one nonspatial generative source. DTT distinguishes its inner production from the outer order in which completed results become accessible. The six inner levels are nested functional dependencies within that production; the seventh denotes outer completion. They are not six independent clocks, six spatial directions, or six simultaneously occupied temporal axes. This distinction makes the framework more specific than a general claim that everything changes: it asks how a world of persistent relations can be generated before its spatial representation is taken for granted.

The experienced present is usually richer than an isolated instantaneous sensation. A spoken word, a rhythm or a movement is apprehended through relations among successive phases. SMM/DTT’s production/completion distinction offers a language for asking how an integrated event becomes available, but it does not make the experience of a present identical to a fundamental cosmic completion. A conscious observer is a complex physical and interpretive subsystem with its own memory, expectations and report capacities.

Three questions should be distinguished. Which neural or functional processes allow information to be integrated? Which processes make that information available for report and action? Why is the process accompanied by experience at all? A theory may make progress on one without settling the others. DTT can contribute a general account of record formation and nested dependencies. To become a theory of consciousness, it would need a specific bridge linking those structures to a subject’s experience. The number of inner levels alone does not select a duration of awareness or a neural mechanism. [3]

03A melody worked through

Hear C, then E, then G. During G, C and E are no longer current sounds in the same way, but their just-past character contributes to hearing an arpeggio. If they were absent from every aspect of experience, the relation among the notes would be lost. If they were experienced as simply simultaneous, their order would also be lost. The present therefore needs differentiated temporal relations, not just a bag of stored contents. Anticipation adds another feature: an expected continuation can be fulfilled or disappointed. The surprise of an unexpected final note depends on an orientation that was already part of the unfolding experience.

04What DTT can contribute

DTT’s distinction between production and completed access can model how a current record includes relations to earlier completions. Its source-memory requirement is therefore relevant to the persistence of temporal context. The phenomenological comparison adds an important constraint: a retained item must not lose its status as just past when it contributes to the present. Merely storing the same data in a buffer does not explain that intentional differentiation. A useful observer model would distinguish an active temporal relation, a recalled representation and a publicly stored record. These can interact without being identical processes or levels of reality.

05A simple dynamical illustration

Consider a retentional variable r updated by rₙ₊₁ = arₙ + (1−a)xₙ, with 0 < a < 1 and input xₙ. A brief input leaves a decaying trace, so the current state depends on recent history. If a = 1/2 and a single unit input is followed by zeros, the trace after its initial update halves at each step. This is a useful memory model, but it has no automatic phenomenological interpretation. It does not establish that the system experiences pastness or anticipation. Its value is to separate a physical mechanism that preserves context from the additional claim that the preserved context appears in a particular way to a subject.

rₙ₊₁ = arₙ + (1−a)xₙ, 0 < a < 1

06Why the six levels are a different structure

The six nested DTT levels describe a proposed generative architecture. Husserl’s retention, impression and protention describe aspects of temporal experience. One list should not be doubled or rearranged to manufacture a numerical correspondence with the other. A meaningful mapping would identify independently defined functions and demonstrate that the same relations are preserved. Longo and Montevil’s work on retention and protention in biological systems illustrates that mathematical bridges can be proposed, while also showing that such bridges are constructions requiring their own interpretation. SMM/DTT can contribute by making its observer and clock definitions equally explicit. [2]

07A stronger account of the observer

The resulting research target is a source-generated observer whose accessible present depends on retained history and structured anticipation, with a clear account of when information becomes usable for action or report. The model should distinguish prediction errors from changes in the external event itself. It should also explain why the temporal integration window depends on the observer’s organization rather than infer a universal duration from cosmic completion. This approach gives DTT a serious connection to phenomenology: both examine how temporal unity is constituted, while preserving the difference between a law of physical generation and a description of lived experience.

08A further conceptual benchmark

Hear the three notes C, E and G in sequence. At the third note, the first two are no longer physically arriving in the same way, yet their temporal relation contributes to hearing an arpeggio. If only the current acoustic sample existed for the listener with no retention, the musical relation would be lost. If the notes were all treated as simultaneous, their order would disappear. The experienced present therefore includes a differentiated relation to what has just occurred. This example motivates a memory-sensitive model of temporal experience, while leaving open whether the relevant unity is explained by neural integration, phenomenological structure or a deeper metaphysical account.
