Synthesis — Relational Potential Across Cosmos, Life, and Mind

From the curvature of spacetime to the firing of neural ensembles, the series we have explored share a common thread: the actualisation of potential through relational alignment. Whether in physics, biology, or cognition, each domain demonstrates how possibility is structured, constrained, and selectively stabilised, giving rise to the phenomena we experience as reality, life, and thought.

1. Relativity: Spacetime as Relational Possibility

Einstein’s theories of special and general relativity revealed that space, time, and motion are not fixed absolutes, but relations among events. The preconditions of relativity — conceptual, semiotic, and operational — allowed a reconstrual of simultaneity, causality, and systemic coherence. Its consequences extended the realm of what could be meaningfully discussed about motion, intervals, and gravitational effects. Here, the universe itself is a network of potential relations actualised through physical constraints.

2. Quantum Mechanics: Probabilistic Semiotics

Quantum mechanics further reframed possibility, showing that fundamental particles are fields of probabilistic potential, constrained by relational laws rather than deterministic trajectories. Superposition, entanglement, and uncertainty are not paradoxes but semiotic features of relational potential at the microscopic scale. QM demonstrates how relational constraints can actualise a landscape of possibilities without privileging a single, pre-given outcome.

3. Natural Selection: Evolution as Relational Semiosis

Darwin and Mendel showed that life is shaped not by fixed essences but by differential actualisation of potential through relational interactions. Variation and selection, underpinned by inheritance, generate patterns of stability that define species, traits, and functions. Evolution becomes intelligible as a semiotic system, where meaning emerges through the selective persistence of relational alignments across generations.

4. Neuronal Group Selection: Mind as Internalised Evolution

Edelman internalised Darwinian logic within the brain, showing that cognition, perception, and consciousness are selectional processes acting on neural potential. Reentrant signalling, neural plasticity, and degeneracy allow patterns of activity to stabilise, creating coherent construals of the world. Thought itself is the microcosmic actualisation of relational potential, a reflexive echo of evolutionary logic.

5. Relational Potential as a Unifying Principle

Across these domains, a single conceptual thread emerges: possibility exists relationally before it is actualised. Constraints — whether physical, biological, or neural — shape the field of potential; selectional processes (causal, evolutionary, or cognitive) actualise patterns that are both coherent and contingent. Meaning, form, and stability are the traces of these actualisations, not pre-given entities.

• Physics demonstrates potential relations at the cosmic scale.

• Biology demonstrates potential actualised through differential persistence.

• Neuroscience demonstrates potential actualised within the system itself.

Together, these series illustrate a multi-scalar relational ontology: a unified perspective in which the universe, life, and mind are all fields of semiotic and relational potential, continuously constrained, differentiated, and stabilised through processes of selection and alignment.
