There is a recurring nineteenth-century report, often retold in popular science contexts, describing a large-scale panic among sheep in parts of rural Britain.
In some versions, a single disturbance is said to have triggered a wave of panic spreading across vast distances.
In more careful historical accounts, the phenomenon appears to have been localised and poorly understood, with no agreed causal explanation, but involving unusually widespread and near-simultaneous flock disruption across multiple farms.
Whether or not the strongest versions of the story are accurate in detail is not the concern here.
What is of interest is that the narrative persists at all, and that it consistently takes the form of a propagating wave of coordinated behavioural change in a non-human population.
This makes it a useful case for thinking about the organisation of possibility in non-semiotic systems.
No communication required
It is tempting to interpret such accounts in terms of transmission:
However, this interpretation already imports a semiotic structure that is not required by the phenomenon.
No representation need be shared.
No message need be transmitted.
No collective awareness need be assumed.
What is sufficient is that individual organisms are embedded in a shared field of constraint and coupling.
Value-guided systems
Each sheep is a value-organised system.
Its behavioural possibilities are structured through differential constraints such as:
At any moment, behaviour is the actualisation of a structured field of possibilities, not the execution of a discrete decision.
A change in environmental conditions does not “instruct” behaviour.
It reorganises the structure of available possibilities.
Local perturbation
A disturbance affecting one organism does not need to be interpreted as a signal in order to have system-wide effects.
It is sufficient that:
a local field of possibilities is reorganised
that reorganisation is expressed behaviourally
and that behaviour itself alters the environmental conditions for nearby organisms
The key mechanism is not transmission, but coupling.
Cascading reorganisation
Once coupling is established, a chain of reorganisation can occur.
Each organism’s actualisation:
What appears from a distance as a wave is, in fact, a sequence of locally situated reconfigurations of possibility structure.
There is no global carrier.
There is no unified state being transmitted.
There is only distributed change in constrained systems.
The illusion of propagation
The “wave” metaphor arises from a particular perspective:
an external observer aggregates temporally and spatially distributed local events into a single continuous narrative.
From within the system, nothing propagates.
Each organism simply encounters a changed field of possibility and acts accordingly.
The sense of movement across a landscape is a product of observational compression, not system-level transmission.
Social organisation without semiosis
What is notable is that this form of coordination does not require:
Yet it still produces structured, large-scale behavioural coherence.
This suggests that social organisation can occur at a level prior to semiosis.
The relevant unit is not meaning, but the coupling of value-organised systems through environmental and behavioural feedback.
Possibility as the operative medium
What is being reorganised in such events is not information, in any strict sense, but possibility.
Each organism exists within a structured field of behavioural potential.
That field is continuously reshaped by:
A so-called “panic wave” is therefore better understood as:
a distributed reconfiguration of overlapping possibility fields across a coupled population
No centre, no message, no representation
From this perspective, three familiar explanatory assumptions become unnecessary:
What remains is a dynamic relational structure:
A minimal model of social coordination
This kind of case is useful precisely because it is minimal.
It shows that:
It is sufficient that value-organised systems are coupled such that each actualisation contributes to the organisation of possibilities for others.
Closing reflection
The story of the sheep panic is often told as a curiosity, or as an anecdote about mass behaviour under mysterious conditions.
In the present framework, it can be read differently.
It is not an exception to normal social explanation.
It is a stripped-down instance of social organisation itself:
No wave travels across the landscape.
Only possibilities reorganise, locally and continuously, until the system settles again.
