Vision and the Non-Semiotic Ground of Experience — 8 The Illusion of Visual Thought: When Construal Is Projected Back Into Perception

With language in place, construal becomes available as a general operation.

Experience can now be:

  • categorised

  • described

  • related

  • interpreted within symbolic systems

This creates a subtle but powerful tendency:

to treat perception itself as already organised like language.

That is the illusion.


1. The Seduction of Retrospective Construal

Once language is acquired, it becomes difficult to remember what experience is like without it.

We begin to retrospectively impose construal onto perception:

  • we say we “recognise” objects as if they were already categorised

  • we describe perception as if it were structured by concepts

  • we treat seeing as if it were already a form of understanding

But this is a projection.

What language enables at the semiotic level is mistakenly attributed to the perceptual level.


2. Vision Operates Without Propositions

Vision, as examined in earlier posts, operates through:

  • differentiation of the visual field

  • stabilisation of patterns

  • recognition via value-based responsiveness

  • attention and salience

None of these require:

  • propositions

  • categories as linguistic constructs

  • symbolic predication

  • explicit relations of the kind found in grammar

Vision does not say:

“this is a chair.”

It simply:

differentiates a pattern that supports action, orientation, and response.


3. Recognition Is Not Interpretation

Recognition can feel like interpretation.

But structurally, it is not.

Recognition:

  • matches current input with stabilised biological sensitivities

  • enables rapid coordination with the environment

  • operates without symbolic mediation

Interpretation, by contrast, involves:

  • construal through a semiotic system

  • assignment of meaning relations

  • articulation within a network of categories

Conflating the two is the root of the illusion.


4. The Grammar of Experience Is Not in the Eye

Language introduces grammar:

  • relations between participants, processes, and circumstances

  • structured representations of events

  • hierarchies of clauses and constituents

It is tempting to believe that perception already contains something analogous.

But grammar is not in the visual system.

It is:

a property of semiotic organisation, not of perception itself.


5. Visual Experience Without Linguistic Framing

Prior to linguistic framing, visual experience is:

  • continuous rather than segmented into named objects

  • gradient rather than discretely categorised

  • responsive rather than propositional

  • value-sensitive rather than conceptually structured

It supports action and coordination without requiring description.


6. The Post-Linguistic Overlay

Once language is learned, perception becomes overlaid with linguistic structure:

  • objects are named

  • categories are invoked automatically

  • relations are inferred through learned schemas

  • interpretations arise alongside perception

This overlay is so habitual that it becomes transparent.

We no longer notice:

the distinction between seeing and saying.


7. Visual Thought as a Category Error

The notion of “visual thinking” often arises from this conflation.

It assumes that:

  • images are already structured like propositions

  • perception already contains conceptual content

  • visual experience is a form of internal language

But this mislocates semiotic structure within biological processes.

What is actually happening is:

perception provides a structured field of value,
which language can then construe.

To reverse this relation is to confuse the strata.


8. What Images Actually Do

Images, whether mental or external, do not inherently think.

They:

  • present patterns of differentiation

  • afford recognition and attention

  • evoke responses shaped by biological and social value

When images appear to “carry meaning,” it is because:

they are being construed within a semiotic system.

The meaning is not in the image itself.

It is in the construal applied to it.


9. The Persistence of the Illusion

The illusion persists because:

  • language is deeply integrated with perception

  • construal happens rapidly and automatically

  • social environments reinforce interpretive framing

  • communication relies on treating perception as already meaningful

As a result:

we habitually treat the outputs of construal as if they were properties of perception.


10. Clarifying the Distinction

The distinction can now be stated cleanly:

  • Vision: operates through biological value, differentiation, recognition, attention, and shared salience

  • Language: operates through semiotic construal, categorisation, relation, and symbolic organisation

The illusion of visual thought arises when:

the operations of language are projected back onto the operations of vision.


11. An Eighth Position

The claim is not that vision is impoverished.

It is that vision is structurally different from language.

Vision does not think in images;
rather, language construes images as meaningful.

Recognising this prevents a category error that obscures the stratification of systems.

It also clears the way for the final step in this series:

understanding how vision becomes captured by meaning once construal is fully operative.

That is the subject of the next post.
