Mathematics and Phenomenology

Mathematics Begins Not with Proof, but with Vision

The stereotypical image of mathematics revolves around proof. But proof belongs to a later layer. What comes first is not a deduction, but a vision. This is precisely why mathematical thinking cannot be reduced to mechanically following rules. In its living practice, mathematics begins not with a chain of reasoning, but with the sudden discovery of a structure. This idea fits well with the way contemporary philosophy of mathematics understands the structural character of mathematical knowledge. (Stanford Encyclopedia of Philosophy)

The mathematician Vavilov writes: “You cannot know mathematics, but you can be a mathematician. Being a mathematician means, first and foremost, seeing: possessing a kind of super-vision that allows you to look through walls and over barriers—Ma chi ha gli occhi nella fronte e nella mente.”

Here, the distinction between using mathematics and thinking mathematically becomes especially clear. Mathematics can be used as a language of operations. Being a mathematician means seeing a structure before it has been fully articulated in a proof.

It is therefore more accurate to say: proof is a form of legitimization of mathematical thought, but not its source. Its source lies in a new way of seeing.

How do we actually think? We literally play out scenes in our minds over and over, performing mental actions and trying to achieve a result, trying to find that self-evident action we can be certain of. Intuitively, this involves a deep faith that movement within us is analogous to movement outside us.

All mathematical axiomatics—and therefore metaphysics and causality as well—grows out of the human scale and everyday experience. If the world were built from the basic properties of matter, it would be logical to suppose that mathematics could also grow out of less obvious axiomatic foundations. This seems to have been Russell’s starting point as he tried to kill off metaphysics in his The Principles of Mathematics. But the deeper we go into the structure of matter, the more cumbersome and sophisticated the mathematical apparatus becomes.

I see two possible reasons for this.

  1. An individual unit of matter has no meaning in itself, and in trying to get at it, mathematics becomes increasingly complex because it has to carry with it an ever more encompassing description of the world.
  2. Perhaps human beings exist at precisely this scale and in this place because it is from this position that causality becomes possible as an organization of being.

In theory, mathematics based on non-anthropic principles is possible. In practice, however, it seems unlikely that we could construct a mathematics that would be self-evident to a hypothetical being in the quantum world, founded on that being’s self-evident axioms, and from which our three-dimensional world and the natural numbers would follow. It would more likely loop back on itself.

At the same time, our mathematics grows out of basic everyday experience. From an early age, at least, we already understand such things as adding or subtracting 1, or the difference between 1 and 2. Human beings think in terms of causality and the past, carrying over some of the actions performed on material objects to objects of thought.

Mathematics is a specialized metaphysics that is simultaneously within the world of embodiment and outside it, as a rupture. Similarly, philosophy is at once the philosopher, the philosopher’s life, the time in which that life unfolds, and a rupture with that time as its stage.

The initial axiomatic foundations of mathematics originate neither in matter as such nor in pure logic, but in the stable phenomenological experience of the world.

Roman Mikhailov’s Lecture

As an example of a mathematician’s way of thinking, I would like to turn to the video lecture “Ravinagar: A State of Identification of Space, Psyche, and Grammar” by Roman Mikhailov, a mathematician and Professor of the Russian Academy of Sciences. In his eccentric, meandering manner, he talks about proliferating patterns, the psyche, his grandmother who worked as a seamstress, sects, and mathematics. But if we listen more closely, a coherent way of thinking emerges from this stream.

Mikhailov’s Patterns

My understanding of mathematics is not sufficient to fully grasp what kinds of patterns Roman is discussing in his lecture. I can only approach them indirectly. The first level of mathematical understanding here probably involves groups of symmetry transformations. Group theory allows us to consider an object through transformations that preserve its shape or essential properties. This is why it is naturally connected with symmetry, ornament, and pattern. The artist M. C. Escher, though not himself a mathematician, illustrated groups of transformations in his work.

In his research, Mikhailov explores the next “level.” In his survey Homotopy Patterns in Group Theory, he explicitly states that the difficulty of certain classical problems in group theory is actually homotopical or homological in nature: derived functors, homotopy groups of spheres, group homology, and other structures arise naturally in purely group-theoretic questions. In effect, he is saying that “pure” group theory is not enough: deeper patterns of a different kind begin to emerge within it.

This seems to be the mathematics he has in mind when he speaks of fractality, multiplicity, ruptures, and domination.

What matters for our purposes is that he seems to experience an outwardly dry, neutral, abstract mathematics as something personal, connected with concrete childhood experience. At one point in the lecture, he describes his experience as follows: the goal is always rational, but behind it there is always a manifold, fractal pattern. His mathematical-mystical performance reaches its peak when he says that he is fighting a “proliferating fractal” that will “send him to the gas chamber.” This is not madness, but rather the living, undisguised existential thinking of a professional mathematician. He offers a glimpse of how highly abstract theories come together, out of the multiplicity of lived experience of being-in-the-world, to form a total, impersonal gaze—a pattern, in his terminology.

From a philosophical perspective, behind these “patterns” and his personal vocabulary of “fascism” and “schizophrenia,” one can discern Deleuze and Guattari’s rhizome, albeit inverted in form. Mikhailov’s fractal, total pattern corresponds, in the vocabulary of postmodernism, to “grand narratives,” while the ruptures are the living proliferation of the rhizome. Mikhailov says that “you need to accept the pattern, and it needs to accept you.” This reveals how his thinking works: he experiences mathematical abstractions bodily, as fate, and lives his life through them. Mathematical structures constitute his lived perception of the world, just as his grandmother, the seamstress, perceives the world through clothing.

It is worth observing how animated he becomes when the discussion turns to “what lies beyond”—to how, “beyond infinity,” topologies are no longer equal and a “new world” opens up. It is clear that this is a significant transcendent experience for him, something of which, even if no one else understands it, he would still “not be ashamed before God.” Proof itself, meanwhile, is “technical work”: he respects its complexity and virtuosity, but still regards it as a craft rather than the central source of meaning.

I think a parallel can be drawn here with the “ontological gesture”: an impossible leap into the beyond that unfolds a new world and a new reality through a new way of seeing.

Long-retired mathematician here. Put succinctly, it takes an active imagination and desire to explore to move the mathematical needle and produce new and interesting results. Proving these results can be illuminating as well, for new portals of discovery can appear in the process.

Nice to see you talking about math lately !

We might say that a proof is used to communicate insight.

This “insight” is a (new) “seeing into” an old situation. Phenomenological foregrounding of the typically recessed.

I agree with you if we are talking about the natural numbers as a basis. Some mathematicians are more “linguistic.” The constructivists and intuitionists can be seen as wanting to stick with our “immediate insight” into natural numbers as “more certain” or “more foundational” than linguistic ( set theoretical ) discourse.

My take on Plato’s unwritten doctrine is that Plato saw “the one” as a brute fact of human experience. The world is “just there” as a system of things that each “count as one.” A thing as such is a “unity.” The “unit” is the generic thing.

The world is also a rushing continuum of “quality.” The unified thing stinks or burns or pushes back. But this quality is always already chunked.

So math gives us a kind of mostly de-qualified ontology. It applies to many situations by “ignoring” quality.

Great stuff to share ! Thanks !

It’s like the “madness” of sanity itself. Of a quest toward a recognized order.

Right. I’m tempted to invoke “poesis” or metaphor. A leap is made by an individual. This leap is motivated. It’s a leap toward something glorious, something rich and strange.

As proofs become pure formality, they also become meaningless. “Correctitude” is the primary virtue only for the dead.

I’m not a mathematician, but I suppose the Greek philosopher Pythagoras was — in a primitive, pioneering way. After his experiments with harp strings, he concluded, “There is geometry in the humming of the strings. There is music in the spacing of the spheres”. And Protagoras may have intended something like your notion of human scale, in his quote, “Man is the measure of all things”. Hence, Da Vinci illustrated the “Divine Proportion” (Golden Ratio) in the human body. Mathematics may be a form of Phenomenology 1, in the sense of embodied experience.

So, I guess instinctive mathematicians 2 are able to intuitively “see” or “feel” the mathematical ratios and proportions of Nature. That may be why many mathematicians are also musicians or artists : e.g. Einstein and his violin. He was quoted, “If I were not a physicist, I would probably be a musician. I often think in music. I live my daydreams in music. I see my life in terms of music.”

Carrying Da Vinci’s concept further : Man is a microcosm of Nature, and Mankind grew out of the earth : “homo sapiens” refers to “hummus” (soil, clay). So Geometry is in our bones, so to speak. In a philosophical sense, "all math boils down to geometry"3. :grinning_face:

1. Mathematics and phenomenology intersect by treating mathematical objects not as abstract entities existing independently in a detached realm, but as structures constituted through human consciousness and lived experience.

This sounds quite close to Leibniz’s monads to me. If a thing as such is already a unity, then the question becomes what makes it genuinely one rather than merely an aggregate. Leibniz seems to radicalize precisely this problem: a true unity cannot ultimately be composite, hence the monad as a simple substance.

I’m fond of Leibniz, and my own “ontological perspectivism” is arguably a mutation of his monadology.

To me we just “in fact do” enact the unity of shared objects. You and I “take for granted” the unity of the entity Leibniz. We “intend” the same unified person singular.

If one doesn’t assume a bifurcation of reality, so that experience is “other” than a “true reality,” then our “living together among unified objects” is just a “given” or “brute” fact. Then we can read Plato as a phenomenologist and not as a mystic or as a generator of mere speculations.

Viewed this way, we do have a “quasi-hylomorphism” of the “continuous quality” of the world that we live as “digitized.” Basically we live among shared qualitative objects that each “count as one.” It’s even hard to try to point at the “continuum,” for each of our signs “counts as one.” We tend to categorize the world, think in terms of “named stuffs.”

“Quality” is an attempt to point at a “non-stuff” (“chora”, “indefinite dyad”) or an “ur-stuff.” It’s the “matter” of “genuine materialism.”

It’s curious how much I’ve noticed language can shape thought. In particular, unity can be expressed quite naturally through the articles a and the. Russian has no grammatical way of marking definiteness or indefiniteness, so many English sentences would sound almost tautological if translated literally into Russian.

It’s worth noting maybe that mathematicians tend to understand one another. But I find it plausible to “living English” is different than living a very different language. I wish I could read Russian, because I have Markov’s book in Russian as a pdf, but I can’t find a pdf translation.

Putting that aside, perhaps you’ll agree that we perceptually “live” objects as unities, at least when they emerge from what Heidegger calls “circumspection.”

English seems somehow better suited to programming or abstract concepts. The words are short, often polysemous, and the grammar is simple and clear. Besides a/the, much/many is another good example: in Russian, these correspond to a single word, and the distinction is not always obvious to Russian speakers. I once came across an explanation of this distinction intended for small children who were native English speakers. For Russians, the distinction is often not obvious, yet it represents a fairly important abstraction that relates to Cantor’s concept of sets. Russian, on the other hand, has more constructions for expressing emotions and personal attitudes.

Regarding how mathematicians understand one another: if I remember correctly, I once read in one of Penrose’s popular books on consciousness that, as a child, he sometimes felt misunderstood and expected to find understanding among fellow mathematicians at university. Yet he soon discovered that their phenomenological experiences could differ: some think visually, others almost tactilely, and others in terms of schemas. This, incidentally, is precisely the mystery: how can different phenomenological experiences lead us to the same thing—something that, moreover, seems to exist in a world of its own (Platonism)?

It’s not just different phenomenological experiences between people that has to be explained in order to understand how we construct the concept of number. Number is more fundamentally a matter of how the different phenomenological experiences within a single individual are bypassed or bracketed.

Counting is a method which both depends on the empirical world and abstracts away from the qualitative features of that world. Numeric units originate with the thinking of a multiplicity, followed wby the intent to ignore everything about the members of that multiplicity besides the concept of ‘same thing, different time’. Number is a special kind of unity, wherein all meaningful qualitative difference has been removed, so that what is left is an empty placeholder.

Counting is less a description of the world than it is how the world looks once we have turned our backs on everything substantively intrinsic to that world other than an empty ‘again and again’.

Number is an important, but not the only, way to describe the world. Adding one is like saying “the next one,” whatever we are referring to. But numbers are not necessarily the only starting point for mathematics. Elementary geometry, for example, need not involve numbers at all.
