Computation did not emerge ex nihilo. It is not the product of a technological epoch, but the actualisation of deeper relational and semiotic conditions already implicit within the human capacity for symbolic construal. To understand computation relationally is to treat it not as a machine process, but as a way in which potential is organised, stabilised, and made traversable through construal.
1. The Relational Substrate: Mathematics and Logic as Proto-Computation
Before computation could be performed, it had to be possible. That possibility lay in the prior construction of relational systems capable of sustaining formal operations. Mathematics provided the architecture of structured potential — number, relation, transformation — while logic provided the architecture of conditionality — consequence, consistency, entailment. These two together formed a semiotic field within which relations could be expressed as manipulable form.
But this field remained inert until the conditions for execution were established. Logic and mathematics gave us what could be done; computation would later make those potentials doable.
2. Formalism and Recursion: Symbolic Infrastructures of Execution
Computation depends on a semiotic cut — a recursive separation between sign and operation, representation and execution. Symbolic formalism enabled this separation by stabilising relations as manipulable entities: symbols, expressions, formulas. To compute is to re-enter this symbolic field, to act upon its forms as though they were objects — to instantiate potential through a second-order construal of the symbolic system itself.
Recursion thus becomes the essential precondition: the system must be able to construe its own construals. This meta-semiotic reflexivity — the ability to interpret, transform, and re-actualise symbolic structures — is what makes computation thinkable before it is executable.
3. Coding and Convention: Social Infrastructures of Stability
Every computation presupposes a code — a system of correspondences that constrains the play of symbols. Such codes are not purely technical; they are semiotic conventions that stabilise potential within a social horizon of interpretation. Binary logic, algebraic notation, programming languages — each represents a collective construal of what counts as meaningful operation.
In this sense, computation rests on a semiotic social contract: a collectively maintained system that permits meaning to function as executable instruction. The “universality” of computation is therefore not metaphysical but infrastructural: it depends on stable conventions that coordinate symbolic action across contexts.
4. Semiotic Grounding: From Symbol to Operation
The decisive shift in the emergence of computation is not the invention of machinery, but the conversion of symbol into operation — the recognition that symbolic structures can themselves do work. A formula becomes an instruction; an inference becomes a procedure. This marks a new phase of construal: meaning itself becomes functionalised as activity.
In SFL terms, we might say computation re-realises semantics as procedure — meaning construed not as value but as executable relation. It is a semiotic technology of actualisation: a way of making potential traverse its own architecture.
5. Summary: Computation as the Reflexive Turn of the Symbolic
Computation emerges where the symbolic field folds back on itself, where construal becomes executable. Its preconditions are not mechanical but relational: the alignment of mathematical structure, logical consequence, and semiotic reflexivity into a coherent architecture of potential. What computation adds — as we shall see in the next post — is the capacity to actualise these potentials dynamically, to make relational form itself productive.
