From Myth to Philosophy to Science: 5 From Philosophy to Science

The reflexive turn of the Pre-Socratics opened the horizon for philosophy, but it remained propositional and largely congruent in wording. The next semiotic expansion occurs when meanings themselves are repackaged through grammatical metaphor, enabling systematic theorising — the foundation of modern science.

1. The Limits of Congruent Propositional Discourse

Early philosophical statements — “All things are water,” “Everything flows,” “Being is” — operate congruently:

• relational meanings are realised in simple clauses

• abstract principles are expressed propositionally

• reasoning remains linear and discursive

While this allowed reflection on semantic values, it did not yet allow complex manipulation or combination of abstract meanings.

Science requires a new semiotic capacity: the ability to pack semantic potential into dense, manipulable forms.

2. Grammatical Metaphor: Packaging Abstract Meaning

Grammatical metaphor allows a meaning normally realised congruently by one clause type to be realised in a different grammatical form, often nominalised:

• “Everything flows” → “The flux of all things”

• “All things are water” → “The material principle of water”

This shift enables:

1. Nominalisation — turning dynamic or relational meanings into entities that can be referred to, compared, and manipulated.

2. Dense abstraction — combining multiple principles in a single, manipulable statement.

3. Systematic reasoning — propositions about abstract entities can now be related hierarchically, formally, and theoretically.

In SFL terms:

• Semantic stratum: abstract meanings are maintained

• Lexicogrammar stratum: grammatical metaphor allows congruent meanings to be realised as dense nominal forms

• Context: scientific discourse emerges as a highly manipulative, theoretical mode

3. From Philosophical Reflection to Scientific Theory

The key consequence is that abstract semantic values, previously objects of reflection, become formalised tools for reasoning:

• Heraclitus’ “flux” becomes a principle that can be studied, compared, and applied across phenomena.

• Thales’ “water” can now be theorised as a material principle within systematic frameworks.

• Relations like cause, effect, and conservation can be expressed independently of narrative or story.

Science, in this sense, is the culmination of the semiotic expansions we have traced:

1. Myth: meaning projects outward onto phenomena via lexical metaphor

2. Philosophy: relational meanings operate across domains, reflexively constraining semantic potential

3. Science: abstract meanings are grammaticalised, packaged, and manipulated for systematic theorising

4. The Horizon of Possibility Opened

Grammatical metaphor allows semantic meanings to be nominalised and recombined, producing:

• general principles

• theoretical models

• systematic explanations of phenomena

Meaning has now moved from:

• projected narrative → reflexive principles → manipulable theoretical entities

This is the final semiotic expansion in the trajectory from myth to philosophy to science. Each stage opens a new horizon of possibility for human meaning-making.

5. Conclusion: The Semiotic Arc

The series has traced a coherent progression:

1. Mythic symbolism creates worlds through metaphor

2. Relational meanings in myth remain bound to narratives

3. Semantic reflexivity arises in the Pre-Socratics when meanings themselves become objects of construal

4. Philosophy systematises and argues about these meanings

5. Science manipulates abstract meanings using grammatical metaphor

The horizon of human possibility is thus continually expanded by new configurations of meaning, each building upon the last.
