An Embodied Mathematics: How the Mind Creates Mathematical Truth
Why Read This
What Makes This Article Worth Your Time
Summary
What This Article Is About
Herbert Harris proposes that mathematics emerges from the brain’s recursive self-modeling capacity rather than being discovered in a Platonic realm or purely constructed by the mind. Drawing on active inference from neuroscience and Douglas Hofstadter’s concept of strange loops, he argues that mathematical thinking arises when the brain models its own modeling processes. This embodied cognition allows humans to grasp abstract concepts like infinity, continuity, and identity through lived experience rather than mere symbol manipulation.
The article traces this idea through number systems, geometry, and modern Homotopy Type Theory (HoTT), which redefines mathematical equality as transformation paths rather than static equivalence. Harris concludes by examining artificial intelligence’s capacity for mathematical understanding, arguing that true comprehension requires not just computational power but the recursive self-awareness that develops through social interaction. This “Goldilocks ontology” positions mathematics between Platonism and intuitionism—real yet inseparable from the living minds that generate it.
Key Points
Main Takeaways
Mathematics from Recursive Consciousness
Mathematical thinking emerges from the brain’s ability to model its own modeling processes through recursive self-awareness.
Active Inference Shapes Understanding
The brain constructs predictive models and updates them through active inference, creating mathematical intuitions through embodied experience.
Fluid Identity Over Fixed Tokens
Human cognition grasps partial identities and transformational equivalence, unlike computational systems that require absolute token matching.
HoTT Reflects Embodied Logic
Homotopy Type Theory redefines equality as transformation paths, unintentionally formalizing how human minds naturally understand sameness.
A Goldilocks Ontology
Mathematics exists between Platonism and intuitionism—real yet inseparable from the embodied minds that generate and recognize patterns.
AI Lacks Embodied Understanding
True mathematical comprehension requires recursive self-modeling that develops through social interaction, not just computational symbol manipulation.

Main Idea
Mathematics as Embodied Recursive Cognition
The article proposes that mathematical knowledge emerges from the brain’s capacity for recursive self-modeling rather than being discovered in an abstract realm or purely mentally constructed. Harris argues that when the brain models its own modeling processes through active inference, it creates the conceptual structures we recognize as mathematics. This embodied perspective dissolves the ancient dichotomy between mathematical discovery and invention by positioning mathematics as patterns emerging from living, self-aware systems.
Purpose
To Bridge Philosophy, Neuroscience, and Mathematical Foundations
Harris aims to synthesize insights from ancient philosophy, contemporary neuroscience, and modern mathematical foundations to offer a novel understanding of mathematical cognition. By connecting Plato’s innate knowledge, Hofstadter’s strange loops, active inference theory, and Homotopy Type Theory, he attempts to resolve longstanding philosophical debates while illuminating what distinguishes human mathematical understanding from artificial intelligence’s computational capabilities.
Structure
Historical Foundation → Neuroscience → Mathematical Theory → AI Implications
The essay begins with the ancient philosophical debate between discovery and construction, then grounds its argument in contemporary neuroscience and cognitive theory. It traces how recursive self-modeling manifests through number systems and geometry before connecting to Homotopy Type Theory as mathematical formalization of embodied logic. The piece culminates by examining AI’s mathematical capabilities through this embodied lens, questioning whether machines can achieve genuine mathematical understanding without recursive self-awareness developed through social interaction.
Tone
Philosophical, Speculative & Integrative
Harris writes with a contemplative, exploratory tone that invites readers to reconsider fundamental assumptions about mathematical knowledge. The prose is thoughtful and measured, weaving together disparate fields without claiming definitive proof but rather offering a compelling synthesis. The tone balances intellectual rigor with accessibility, using vivid metaphors like “Goldilocks ontology” and concrete examples while engaging seriously with complex philosophical and technical concepts.

FAQ
Frequently Asked Questions
Recursive self-modeling refers to the brain’s capacity to create models of its own modeling processes, forming what Hofstadter calls “strange loops.” When the brain’s inferential looping “turns back on itself to predict its own predictions,” it achieves recursion. This second-order cognition allows humans to imagine how their thoughts appear to others, simulate counterfactuals, and assess their own reasoning—capabilities that transform how we understand abstract concepts and create mathematical structures.
Active inference describes how the brain constructs predictive models of sensory states and actions, then constantly updates these predictions when reality surprises it. This process provides the cognitive foundation for mathematical intuition by allowing the brain to “smooth over discontinuities” and create a lived sense of continuity. When this inferential process becomes recursive, it generates the capacity to manipulate abstract mathematical objects and understand transformations between different representations.
The Goldilocks ontology is a middle path between Platonism and intuitionism—”neither too intuitionistic nor too Platonistic.” It suggests that mathematical structures are not “out there” in a timeless realm waiting to be discovered, nor are they mere psychological projections. Instead, they are patterns that emerge when embodied minds model their own modeling, making them “stable enough to count as real, yet inseparable from the living systems that generate and recognize them.”

Our Ultimate Reading Course offers 365 articles with 2,400+ questions to systematically improve your reading comprehension skills.
This is an Advanced-level article requiring familiarity with philosophical argumentation, abstract mathematical concepts, and interdisciplinary synthesis. It assumes readers can follow extended theoretical discussions spanning ancient philosophy, contemporary neuroscience, and cutting-edge mathematical foundations. The text demands comfort with specialized terminology, the ability to trace complex chains of reasoning across multiple domains, and capacity to evaluate speculative proposals about the nature of consciousness and mathematical truth.
The article argues that humans develop self-awareness through social developmental processes where “we learn to see ourselves through others’ eyes.” From parents and caregivers to colleagues, we constantly gather information about ourselves as others model us and we model their models. This social recursion cultivates the “nuanced fluidity of identity needed for mathematical reasoning”—the ability to understand transformational equivalence and partial identities that characterizes sophisticated mathematical thinking, something isolated computational systems cannot achieve.
