A structural theory of everything

In this paper it is argued that Barad’s Agential Realism, an approach to quantum mechanics originating in the philosophy of Niels Bohr, can be the basis of a ’theory of everything’ consistent with a proposal of Wheeler that observer-participancy is the foundation of everything. On the one hand, agential realism can be grounded in models of self-organisation such as the hypercycles of Eigen, while on the other agential realism, by virtue of the ‘discursive practices’ that constitute one aspect of the theory, implies the possibility of the generation of physical phenomena through acts of specification originating at a more fundamental level. Included in phenomena that may be generated by such a mechanism are the origin and evolution of life, and human capacities such as mathematical and musical intuition.

💡 Research Summary

The paper proposes a “Structural Theory of Everything” that unites Karen Barad’s Agential Realism with John Wheeler’s participatory‑anthropic principle. Barad’s framework, derived from Bohr’s interpretation of quantum mechanics, treats the quantum event not as a pre‑existing fact but as an intra‑active “intra‑action” between apparatus and measured system. In this view, reality is continuously co‑produced by the act of observation; it is not a static substrate independent of measurement. Wheeler’s conjecture that “observer‑participancy is the foundation of everything” is taken as a broader metaphysical claim that the universe’s laws themselves emerge from participatory acts.

The author argues that these two ideas are mutually reinforcing. By grounding Agential Realism in models of self‑organization—specifically Manfred Eigen’s hypercycle concept—the paper supplies a concrete mechanistic substrate for the otherwise abstract intra‑action. Hypercycles are networks of replicators, catalysts, and information carriers that self‑sustain through mutual reinforcement. The author maps the hypercycle’s recursive feedback onto the quantum intra‑action, suggesting that the very structure of matter and the emergence of life are the result of a self‑referential, participatory loop: observation organizes matter, the organized matter then offers new possibilities for further observation.

A second pillar of the theory is Barad’s notion of “discursive practices.” According to Barad, scientific theories, linguistic symbols, and other representational systems are not merely descriptive; they actively bring new phenomena into being. The paper extends this claim to human cognitive capacities such as mathematical and musical intuition. It posits that when a mathematician introduces a new definition, the definition does not merely label an existing structure; it creates a new structural possibility that can be instantiated in physical or biological systems. Similarly, a musical phrase reorganizes neural circuitry, generating novel affective states that feed back into the body’s physiological processes. In this way, the author claims that high‑level human cognition is another layer of intra‑action that can shape the material world.

The synthesis yields several key insights:

1. Unified participatory mechanism – Both quantum events and biological self‑organization are described as emergent from a single participatory loop, dissolving the traditional boundary between physics and biology.

2. Concrete dynamical substrate – Hypercycles provide a mathematically tractable model for how intra‑actions can generate stable, self‑replicating structures, bridging the gap between abstract philosophy and empirical science.

3. Generative role of language and symbols – Discursive practices are treated as causal agents; they can instantiate new physical configurations, thereby extending the scope of scientific explanation to include cultural and artistic acts.

4. Re‑framing of the “observer‑independent” assumption – The paper challenges the classical view that the universe exists independently of measurement, arguing instead that reality is a co‑construction of observers, instruments, and the discursive frameworks they employ.

By integrating these strands, the author proposes a comprehensive, cross‑disciplinary framework that claims to explain the origin of life, the evolution of complex adaptive systems, and the emergence of uniquely human capacities—all as manifestations of a single, underlying structural process rooted in observer‑participancy. The work is speculative and highly interdisciplinary, but it offers a bold philosophical architecture that could inspire new research programs at the intersection of quantum foundations, systems biology, and cognitive science.
