Drawing on biological examples such as:
- the genetic code,
- cellular signalling systems,
- and regulatory networks,
biosemiotics suggests that life is structured through:
systems of encoding and decoding.
This appears to provide exactly what earlier concepts lacked:
- a stable structure,
- a repeatable mapping,
- and a concrete instantiation of meaning.
If signs risk becoming too diffuse, codes seem to bring them back under control.
But this stability is deceptive.
1. What a Code Presupposes
In its strict sense, a code involves:
- a mapping between two domains,
- a set of rules governing that mapping,
- and a system in which these mappings function.
For example:
- sequences of nucleotides correspond to amino acids,
- signals correspond to responses,
- patterns correspond to outcomes.
This structure appears to align with semiosis:
- something stands for something else,
- according to a rule.
But this alignment depends on a crucial assumption:
that mapping is equivalent to meaning.
2. The Genetic Code as Paradigm Case
The genetic code is often treated as the paradigmatic example:
- codons “encode” amino acids,
- sequences “carry information,”
- the genome “specifies” the organism.
This language is deeply entrenched.
It suggests that:
biological systems are inherently semiotic because they operate through codes.
But what is actually present is:
- a highly regular mapping between molecular configurations.
That is:
a constraint on transformation.
3. Mapping Is Not Meaning
A mapping, no matter how complex, does not by itself constitute semiosis.
It establishes:
- correspondence,
- regularity,
- and predictability.
But it does not establish:
- aboutness,
- interpretation,
- or construal.
The fact that:
- one sequence leads to a particular outcome
does not mean:
- that the sequence stands for that outcome as such.
It means only that:
under certain constraints, one configuration leads to another.
4. The Illusion of Encoding
The language of encoding introduces a subtle shift.
It suggests:
- that information is contained in one form,
- and translated into another.
But this implies:
- a separation between representation and realisation,
- and a process that preserves meaning across that transformation.
Under constraint, this cannot be maintained.
Because:
there is no independent “information” that exists prior to its realisation.
What we have instead is:
- transformation under constraint,
- not transmission of meaning.
5. Information Without Semiosis
Biosemiotics often relies on the concept of information as a bridge:
- between physical processes and meaning,
- between biology and semiosis.
But information, in this context, typically refers to:
- measurable variation,
- statistical structure,
- or functional organisation.
This is not meaning.
It is:
structured difference.
And while structured difference can support semiosis, it is not itself semiotic.
6. Code as Constraint
If we remove the semiotic overlay, what remains of “code”?
We can state it precisely:
a code is a stable constraint on transformation between configurations.
For example:
- given a codon, a particular amino acid is produced,
- given a signal, a particular pathway is activated.
These are not acts of interpretation.
They are:
regularities in how systems transform under constraint.
7. Where Biosemiotics Overreaches
Biosemiotics overreaches when it treats:
- constraint as encoding,
- mapping as representation,
- and transformation as interpretation.
This produces a layered confusion:
- physical process is described in informational terms,
- informational structure is described in semiotic terms,
- and semiosis is attributed where only constraint is present.
8. Holding the Distinction
To maintain coherence, we must separate three things:
- constraint: what determines how transformations occur
- information: structured difference describable within a system
- meaning: construal within a semiotic organisation
These are related.
But they are not interchangeable.
In particular:
neither constraint nor information is sufficient for meaning.
9. Coupling Without Collapse (Revisited)
This does not isolate semiosis from biology.
Instead:
- biological systems (value) operate through constraint and information,
- semiotic systems (meaning) operate through construal,
and the two can be:
coupled without being reduced to one another.
For example:
- biological constraints may condition what can be construed,
- semiotic activity may be realised within biological systems.
But:
meaning is not encoded in biology.
Closing Formulation
A code does not carry meaning.
It constrains transformation.
Information does not interpret itself.
It describes structured difference.
Meaning arises only where something is construed as something—not where one configuration reliably produces another.
At this point, the major stabilising resources of biosemiotics have been placed under constraint:
- sign (without drift)
- interpretation (without response)
- code (without semiosis)
What remains is its deepest claim:
that life and meaning are continuous.
The next post can now take that directly:
“Continuity Without Collapse: Why Life Does Not Gradually Become Meaning”
That is where the final pressure point lies.
