***(Here Barry Richmond is presented as champion of Systems Dynamics)***

Barry Richmond positions **prose (words)**, **visualization (diagrams)**, and **mathematics (equations/simulation)** as integral parts of a **continuum of activities** that range from the conceptual and expansive to the technical and disciplined\[1\].

### **1\. Prose (Words and Mental Models)**

Richmond identifies prose and spoken language as the starting point of our thinking, but also as a primary constraint.

• **Linear Bias:** He notes that Western languages, like English, are fundamentally linear (noun-verb-noun), which predisposes people to view reality as a series of one-way "x causes y" occurrences\[5\]\[6\].

• **Laundry List Thinking:** In this prose-heavy stage, people often develop a "laundry list" of factors to explain an issue, implicitly weighting them without understanding their circular interdependencies\[7\].

• **Mental Model Amalgams:** Richmond asserts that internal mental models are complex "multidimensional amalgams of images and recollected experiences"\[11\]. While prose is necessary to state a purpose or describe an event, it is often too "vague" and fails to capture the reciprocal relationships of a system\[14\].

### **2\. Visualization (Diagrams and the "Systems Esperanto")**

Richmond positions visual diagramming—specifically the **stock-and-flow language**—as a critical bridge to span the **"vast abyss"** between a messy internal mental model and a functional computer simulation\[11\].

• **Operational Language:** He describes visualization as an **"operational" language** that tells it "like it really is" by identifying the "physics" or infrastructure of a system\[21\].

• **Systems Esperanto:** Richmond views visual icons as a **"Systems Esperanto"** or "lingua franca" that facilitates cross-disciplinary communication, allowing a biologist and an economist to share the same structural framework\[24\].

• **Explicitness:** Visualization forces an **"explicitness" of mental models**, translating individual perceptions into black-and-white pictures that can be scrutinized, debated, and updated by a collective team\[27\].

### **3\. Mathematics (Equations and Simulation)**

At the technical end of the continuum, mathematics and computer simulation are used to **"close the loop"** on a thinker's logic\[2\]\[4\].

• **Quantification vs. Measurement:** Richmond distinguishes between absolute numerical measurement and **"scientific thinking,"** which involves the rigorous **quantification** of even "soft" or non-measurable variables (such as commitment or self-esteem) on a relative scale\[31\].

• **Sanity Check:** For Richmond, simulation is not an "answer generator" but a **"sanity check"** on intuition\[35\]. It verifies whether the structural relationships captured in visualization are actually capable of generating the behavior patterns observed in reality\[2\].

• **Disciplined Thinking:** This stage adheres to rigorous **grammar rules**, such as unit-of-measure consistency and physical conservation laws (respecting that matter cannot be created or destroyed), which prevents "getting something for nothing" in the logic of the model\[23\].

By integrating these three representations, Richmond seeks to create a **"learner-directed"** process where the student is the "construction worker" of their own meaning, using diagrams and simulations to refine their mental models and anticipate the long-term consequences of actions\[39\].

In his work on systems thinking and operations research, Churchman positioned **prose, visualisation, and mathematics** as complementary but hierarchically distinct modes of representing and inquiring into complex social systems.

### 1\. The "Inverted Sandwich" of Representation

Churchman’s most famous positioning of these three elements appears in his seminal 1957 text, _Introduction to Operations Research_. He described the book’s structure as an **"inverted sandwich"**\[1\].

• **Mathematics as the "Daily Bread":** The middle chapters consisted of the technical and mathematical "machinations," such as the simplex algorithm\[1\]. While necessary for calculation, Churchman famously never spoke of the "beauty" of these mathematical pivots\[1\].

• **Prose and Visualisation as the "Meat":** The beginning and ending chapters—the "meat"—used **clear language (prose)** and **diagrams (visualisation)** to bring the systems approach to life\[1\]. These representations were responsible for "securing improvement," as they connected mathematical models to real-world implementation and human values\[1\]\[2\].

### 2\. Symbols in Inquiring Systems

Churchman defined inquiring systems as **symbol processors** where the "material" being processed could take several forms depending on the design choice of the inquirer\[3\]\[4\].

• **Prose:** Represented as sentences or "stories"\[3\]\[5\]. In a Hegelian inquiring system, prose is the primary medium for **storytelling**, using "drama" and conflict to reveal opposing worldviews that mathematical models might hide\[5\]\[6\].

• **Mathematics:** Represented as codes, digits, or formal mathematical analysis\[3\]\[7\]. Mathematics allows for **enormous abstraction**, enabling a designer to extrapolate information across vast reaches of space and time through equations\[8\]\[9\].

• **Visualisation:** Represented as "pictures," "images," or diagrams\[3\]\[4\]. For example, Churchman used **Euler diagrams** in logic to set down the properties of categorical forms in a visual manner\[10\].

### 3\. The Limits of Mathematical Representation

While Churchman was a pioneer of mathematical modeling, he argued that it was often used as a "piece of arrogance" when it claimed to see the "whole elephant"\[11\]. He critiqued the "mathematization" of management science in the 1960s, noting that it often led to **suboptimization**—solving a mathematical puzzle while making the actual system worse\[12\]\[13\].

• He positioned **mathematics as a specialized lens**: A mathematician might see the world as a matrix of number pairs and transformations, but this representation is a **design choice**, not an objective reality\[14\]\[15\].

• He argued that one cannot be **"precise about fuzziness"**; attempting to use mathematics to precisely model the _experience_ of chaos (like a disaster) misses the human point that can only be captured through prose and experience\[16\].

### 4\. Prose as the Domain of the "Soft" and Ethical

Churchman positioned prose (storytelling) as the primary tool for **"soft" scientists**\[17\]. While "hard" sciences like physics and mathematics are direct and forceful, "soft" scientists tell stories about the world's past, present, and future to tease out complexity\[17\]. In his view, the most important aspects of a system—its **ethics and "moral outrage"**—are better germinated through the visceral language of prose (e.g., "kids are starving, damn it all") than through dispassionate mathematical definitions\[18\].

### 5\. Visualisation as a Boundary Critique

In the tradition of Churchman and his student Peter Checkland, visualisation serves to clarify the **subjectivity of an inquiry**\[21\]. Drawing a **boundary** on a map or diagram is a visual act that differentiates the "system of interest" from its environment\[21\]. Visual representations like **"Rich Pictures"** are used to collect as many stakeholder perceptions as possible without initially pressing them into the restrictive "systems terms" of formal logic or mathematics\[22\].

Christopher Alexander positioned **prose, visualisation, and mathematics** as a triadic set of representations used to move design from the abstract understanding of a problem to the creation of a living physical form\[1\]\[2\]. He saw these not as mere descriptions, but as **operative tools** necessary to manage the "organized complexity" of the built environment\[3\]\[4\].

### 1\. Mathematics: The Foundation of Objectivity

Alexander initially used mathematics to provide a **verifiable and unbiased "picture"** of a design problem\[5\]\[6\].

• **Neutralising Bias:** He believed that the human mind often falls into "cognitive handicaps," preferring simple models over the actual complexity of a site\[7\]. Mathematics (specifically set theory and graph theory) allowed him to create a "mathematical picture" that eradicated personal bias and retained only the "abstract structural features" of the problem\[6\]\[8\].

• **Analysing Forces:** Early in his career, he used tools like force analysis and modularization to "bring to heel" the complexity of villages or transit systems\[9\].

• **The Limit of Math:** Later in his life, he admitted that standard mathematics "failed him" when trying to describe the more profound, spiritual geometries of order, leading him to seek a new type of mathematical representation for "wholeness"\[10\]\[11\].

### 2\. Visualisation: The Bridge to Form

Visualisation—primarily through **diagrams and topologies**—served as the "bridge" that turned abstract mathematical requirements into physical geometry\[1\]\[12\].

• **Topologies as Worldviews:** Alexander’s worldview shifted based on what he could visually model: he first viewed problems as **"trees"** (hierarchical), then as **"semilattices"** (overlapping), and finally as **"networks"**\[1\]\[13\].

• **Diagrams as Power:** He stated that diagrams were the "key to the process of creating form" because they captured the **essence of a problem at a glance**\[14\]\[15\]. While mathematics defined the requirements, the "orderly complex of diagrams" (which he later called patterns) actually shaped the form\[2\]\[15\].

### 3\. Prose and Poetry: The Generative Syntax

As Alexander moved away from rigid computer programs, he adopted **language** as his primary generative system\[4\]\[16\].

• **Language as an Operating System:** A "Pattern Language" functions like a computer program but is executed through human prose\[17\]\[18\]. It provides the "syntax" for arrangement, while the user provides the "semantics" based on their specific context\[19\]\[20\].

• **Prose vs. Poetry:** Alexander distinguished between **"mundane linear prose"** (standard design) and **"poetry"**\[21\]\[22\]. He believed that just as a poem uses dense, interlocking meanings to illuminate a whole, a successful design uses overlapping patterns to create a "density" that mundane, segmented planning cannot achieve\[22\]\[23\].

Alexander’s ultimate goal was to find a theory where **"Value and Fact are one,"** essentially using mathematics and visualisation to prove that aesthetic beauty (often described in prose) is an objective, measurable fact\[24\]\[25\].

Alexander's attempt to turn "feeling" and "poetry" into an objective "mathematical syntax" makes design more accessible to everyone but risks making the creative process too mechanical.

Geoffrey Vickers positioned **prose, visualization (graphical representation), and mathematics** as distinct "expressive skills" or languages used by the human mind to order, communicate, and interpret experience\[1\]\[2\]. He viewed these representations not as rivals, but as different "cognitive styles" that should ideally be used in combination to understand complex situations\[3\].

His positioning of these three perspectives can be understood through the following themes:

### 1\. Prose: The Medium of Context and Ideas

Vickers identified **prose** as his own primary medium of expression, a choice he attributed to his **"English classical education"**\[4\].

• **Capturing Complexity:** He used prose to navigate what he called the "world of affairs," arguing that written words were necessary to explore the "history of ideas" and the nuanced "webs of significance" that characterize human societies\[4\].

• **The Power of Imprecision:** He believed that the **"incomparable force of language"** derived from its creative imprecision and "open-endedness," which allowed every generation to redefine essential but ambiguous concepts like "freedom" or "justice"\[7\].

• **Resistance to Formalism:** When challenged by Peter Checkland that a system is most obviously represented through a diagram, Vickers defended prose as his natural medium for articulating the partly tacit "mental evaluative act" of appreciation\[4\].

### 2\. Visualization and Mathematics: Grasping Space-Time Relations

Vickers acknowledged that **visualization (graphical forms) and mathematics** possessed a unique clarity for representing specific types of relationships that prose struggled to convey.

• **Spatial and Temporal Clarity:** He noted that **"relations in space and time are so much more easily grasped when presented in graphical or mathematical form than when expressed in words"**\[10\]\[11\].

• **Cognitive Efficiency:** He viewed tools like maps and graphs as "curiously simple ways of comparing complex relations" that were familiar and intuitive to the human mind\[10\]\[11\]. He classified **graphical and mathematical skills** alongside verbal skills as "basic expressive skills" that education should enable students to master\[1\].

### 3\. The Critique of Mathematical Modeling

While he respected mathematics as a language, Vickers was highly critical of its over-extension into "management science" and policy-making.

• **Neglect of Judgement:** He argued that **"mechanical and mathematical models of decision-making"** tended to emphasize "action judgements" (the _how_) while neglecting the more vital **reality and value judgements** (the _what_ and _why_)\[12\]\[13\].

• **The "Technological Delusion":** He warned that the prestige of the measurable tempted thinkers to **"beat our problems into a shape that our computers can handle"**\[14\]. This created a "delusion" that human problems are merely technical puzzles susceptible to optimal mathematical solutions, ignoring their "messy," value-laden nature\[14\].

• **Hard vs. Soft Systems:** He felt that the dominance of mathematical modeling had "dehumanized" the word "system," embedding it in faculties of technology and making it ill-suited for the "richness of being human"\[17\]\[18\].

### 4\. Synthesis: The Complementary Nature of Representations

Vickers ultimately sought a **dialectical balance** between these perspectives, mapping them onto two fundamental modes of knowing:

• **Rationality (Mathematics/Logic):** This mode is "more dependent on analysis, logical reasoning, calculation, and explicit description"\[19\].

• **Intuition (Prose/Aesthetics):** This mode is "more dependent on synthesis and the recognition of pattern, context and the multiple possible relations of figure and ground"\[19\].

He concluded that **"synthesis and analysis, contextual and causal explanation are distinct though inseparable aspects of human mental process in all mental activities,"** including physics and mathematics themselves\[20\]. For Vickers, the most effective "appreciators" are those who can integrate the logical/explicit with the contextual/tacit\[3\].

John Warfield positioned prose, visualisation (graphics), and mathematics as a **triad of equivalent (isomorphic) communication channels** within his systems science framework\[1\]. He argued that while each language has unique strengths and weaknesses, they must be used in concert to effectively manage the "logistical tyranny" and cognitive load imposed by complex issues\[4\].

His positioning of these three perspectives is structured as follows:

### 1\. Prose as the "Metalanguage"

Warfield identified natural language (prose) as the **metalanguage** of systems science, used to formulate the basic elements and substantive meaning of a problematic situation\[8\].

• **The Limitation:** He famously described prose as a **"Procrustean bed"** because it is inherently **linear**\[11\]. Since complex systems are non-linear, prose alone is inadequate for portraying the rich interweaving of concepts and relationships\[14\].

• **The Role:** Prose provides the "incremental meaning" and real-world context that mathematics lacks\[17\].

### 2\. Mathematics as the "Object Language"

Mathematics (specifically logic, matrix theory, and graph theory) serves as the **object language** used for rigorous, computer-assisted processing\[8\].

• **The Strength:** It provides the "formalism" required to ensure **logical consistency** across hundreds of variables—a task that exceeds the "Miller Index" of human short-term memory\[20\].

• **The Role:** Using **Boolean reasoning** and theorems like **Harary’s Theorem of Assured Model Consistency**, the mathematical perspective allows a computer to act as a "cognitive aid," performing the millions of logic calculations needed to structure a system\[4\].

### 3\. Visualisation as the "Interpretive Bridge"

Structured graphics, particularly **directed graphs (digraphs)**, act as the primary interface between human intuition and mathematical rigor\[27\].

• **The Strength:** Unlike the "serial" nature of prose, graphics take advantage of the human eye's ability to **scan patterns in parallel**, allowing observers to grasp high-level overviews and detailed relationships simultaneously\[30\].

• **The Role:** Graphics translate abstract mathematical matrices into visible structures (such as **problematiques** or **intent structures**) that are easy for "ordinary mortals" to comprehend and interpret\[33\].

### The Requirement of Isomorphism

A central tenet of Warfield's approach is that these three representations must be **isomorphic**, meaning information can be exchanged between them without loss or distortion\[29\]. This is formalised in two key constructs:

• **Model-Exchange Isomorphism (MEI):** A strategy for precisely moving information from a matrix (math) to a digraph (graphics) and back again\[3\].

• **Abstract Relation Types (ART):** A framework used to document a system's structure by providing a dedicated section for each representation: a prose description of the relationship, a formal graphical map, and the executable mathematical code\[39\].

Warfield insisted that any high-quality structural graphic must be **unambiguously translatable back into prose** to ensure it can be validated by the participants who provided the original information\[43\].

Neil Postman positioned **prose, visualization, and mathematics** as distinct "media-metaphors" or **epistemologies** that do not merely carry information but actively re-create the world by dictating what is considered "true," "real," or "intelligent"\[1\]. He argues that each form of representation encourages a different orientation for thought and sensibility, leading to a fundamental shift in how human culture is organized\[1\].

### 1\. The Perspective of Prose (The Typographic Mind)

Postman identifies **prose**—specifically the printed word—as the foundation of the **"Age of Exposition"**\[6\]. He positions this representation as the highest achievement of rational thought for several reasons:

• **Logical Structure:** The printed word demands a "Typographic Mind" characterized by **logic, sequence, history, and detachment**\[7\].

• **Analytic Management:** Writing "freezes" speech, allowing for the continuous and concentrated scrutiny of ideas\[8\]. This fosters what Postman calls the **"analytic management of knowledge"**\[9\].

• **Capacity for Abstraction:** Prose requires the reader to negotiate a world of abstractions, as very few printed sentences require concrete images to be understood\[10\]. Postman defines **intelligence** in a print culture as the ability to dwell comfortably in a field of concepts and generalizations\[11\].

• **Seriousness and Truth:** In this perspective, the "truth" is seen as a product of orderly arguments and objective evidence\[12\]\[13\].

### 2\. The Perspective of Visualization (The Age of Show Business)

Postman positions **visualization**—driven by photography and television—as a **"peek-a-boo world"** that is uncompromisingly hostile to the typographic mind\[14\]\[15\].

• **Fragmentation and Instancy:** Unlike prose, which is sequential, imagery is **fragmented, discontinuous, and emotional**\[7\]\[16\]. It replaces historical perspective with a "continuous, incoherent present"\[17\].

• **The Particular vs. The Abstract:** Photography speaks only in **particularities**\[18\]. While words define the world as an "idea," photographs present the world as an "object"\[19\]. Visuals cannot talk about abstractions like truth, honor, or love; they can only "show," not "talk about"\[20\].

• **Entertainment as Epistemology:** Under the reign of visualization, **entertainment becomes the "supra-ideology"** of all discourse\[21\]. Truth is no longer judged by logic but by the "verisimilitude" or attractiveness of the performer—a state Postman calls "disinformation"\[22\].

### 3\. The Perspective of Mathematics (The Sovereignty of Numbers)

Postman positions **mathematics**—specifically through **statistics and technical calculation**—as the primary ideological tool of **Technopoly**\[25\]\[26\].

• **Objectivity as a Mystique:** Technopoly uses numbers as the ultimate test of objectivity, believing that what cannot be measured either does not exist or is of no value\[27\]\[28\].

• **Reification:** This perspective leads to the error of **reification**, where abstract concepts like "intelligence" or "beauty" are treated as if they were physical things (like a "pancreas") that can be assigned a numerical score\[29\]\[30\].

• **The Devaluation of Judgment:** Postman warns that the "sovereignty of numbers" encourages people to believe that technical calculation is superior to human judgment\[27\]\[31\]. He argues that this results in **"Scientism"**—the illusory belief that standardized procedures can provide a source of moral authority\[32\].

• **Information Glut:** Mathematics, when paired with computers, generates a **"Niagara" of information** that is often useless and serves to bury what is actually necessary to know under a heap of trivia\[33\]\[34\].

### The Conflict of Perspectives

Postman concludes that these three representations are currently in a state of **"total war"**\[35\]. He specifically points to the schoolroom as a battleground where the world of prose (with its emphasis on logic and discipline) is being assaulted by the world of visualization (with its emphasis on imagery and immediate gratification) and the world of mathematics (with its emphasis on standardized testing and calculability)\[7\]. To resist the negative effects of these shifts, he advocates for a curriculum based on the **"ascent of humanity,"** which emphasizes the history and philosophy of all subjects to help students maintain a "psychic distance" from their technologies\[38\]\[39\].

Niklas Luhmann’s positioning of **prose, visualisation, and mathematics** (specifically the **calculus of forms**) as distinct modes of theoretical representation is most clearly articulated in his discussion of how to adequately describe complex social systems like organisations.

According to the sources, Luhmann distinguishes between these three perspectives as follows:

### **1\. Mathematics: The Calculus of Forms**

Luhmann views mathematics, particularly **George Spencer Brown’s calculus of forms**, as a tool for achieving the highest level of **formal stringency and abstraction**\[1\].

• **Irreducibility:** He uses mathematical logic to define a system as a "two-sided form" (the difference between system and environment) using a **single operator**, rather than a collection of terms\[2\].

• **Operational Limits:** While organizations are "more likely to fit the calculus of forms than dialectical theory," Luhmann argues that it is "hardly possible to attribute the stringency of self-calculation" directly to them\[3\]. Complex social systems are "non-trivial" and historical, meaning their internal states make them too unpredictable for simple mathematical transformation functions\[3\].

### **2\. Visualisation: Reduced Overviews and Maps**

Luhmann identifies visualisation as a mode of representation that typically seeks to provide a **"reduced overview"** of reality, much like a **"map does of a country"**\[3\].

• **Characterising Closure:** He cites Talcott Parsons’s use of visual representations—such as **cross-classification tables (the AGIL schema)**—as a technique to consciously characterise the **closure of a combinatory space**\[8\]\[9\].

• **Critique of Simplification:** Luhmann notes that while such overviews are helpful for identifying boundaries, they often fail to capture the **non-calculable, historical, and self-observing** nature of social systems\[3\]. He suggests that a purely visual "map" approach is insufficient for a theory that must account for its own existence as a part of the world it describes\[3\].

### **3\. Prose: The Sociological Text**

Luhmann positions **prose (the written text)** as the primary way for sociology to "go its own way" by **organising observations more stringently than do the systems themselves**\[3\].

• **Stringency without Logicism:** Unlike mathematics, a sociological prose text does not promise "stringency of self-calculation," and unlike a map, it does not merely offer a reduced overview\[3\]. Instead, it uses **language as a medium of communication** to construct a reality that can handle the complexity and "loose couplings" of the social world\[3\].

• **Coordination of Memory:** Written prose is a **functional equivalent for perception**; it serves as the **memory of social systems**, allowing them to coordinate observations across spatial and temporal limits\[12\]. By writing texts, the theorist can "fill in the other-reference" of the system and reflect on its own "blind spot" in a way that formalised logic or visual schemas alone cannot\[15\]\[16\].

In summary, Luhmann positions **prose** as the indispensable medium for sociological analysis because it can navigate between the extreme **formalism of mathematics** and the **static simplification of visualisation**, providing a flexible yet rigorous framework for describing systems that are constantly "calculating their own calculation"\[3\].

Peter Senge positions the three representations—prose, visualization, and mathematics—as complementary "languages" for understanding and communicating systemic reality, each with different strengths and limitations for addressing complexity.

### 1\. Prose (Normal Verbal Language)

Senge positions standard verbal language as the most familiar but also the most **limited** representation for systems thinking.

• **Linear Bias:** He argues that Western languages, with their subject-verb-object structure, are fundamentally biased toward a **linear view**\[1\].

• **Inadequacy for Circularity:** Using prose to describe even simple systems is "extremely awkward" because it forces the speaker to describe reciprocal flows of influence in a step-by-step manner (e.g., "A caused B, which caused C")\[2\].

• **Fragmentation:** Normal verbal language tends to extract simple, linear cause-effect chains from a reality that is actually composed of multiple, simultaneous, and interdependent relationships\[3\].

### 2\. Visualisation (Systems Mapping and Diagrams)

Senge positions visualization as a "new language" of **interrelationships** that moves beyond the limitations of prose\[1\].

• **Seeing the Whole:** Tools like systems mapping and causal loop diagrams allow people to see **"circles" rather than "straight lines"**\[1\]\[4\].

• **Shared Understanding:** Visualization helps stakeholders build a "visual picture" of interdependencies that may be obscured by their individual vantage points\[5\]\[6\].

• **Objectifying Conversation:** These visual representations help teams discuss complex issues more dispassionately by focusing on "the structure" rather than personalities or leadership styles\[7\].

### 3\. Mathematics (Equations and Computer Simulations)

Mathematics and computer-based simulations (microworlds) are positioned as the most rigorous representations for mastering **dynamic complexity**\[8\]\[9\].

• **Handling High Complexity:** Senge notes that while humans have "cognitive limitations" and can only process a small number of variables simultaneously, mathematical models and computer simulations can integrate hundreds of simultaneous feedback processes\[10\]\[11\].

• **A Strategy Tool:** If systems thinking were explained as an **equation**, it would capture how A and B continually interrelate (e.g., "A causes B while B causes A")\[12\].

• **Testing Intuition:** Mathematical simulations allow managers to take their highly systemic intuitions—which often "offend the logical mind"—and conceptualize them into public knowledge that can be tested, challenged, and improved\[13\]\[14\].

• **Relevant Play:** In microworlds, the mathematics of the underlying system dynamics allow for "relevant play," where managers can experiment with policies and see long-term consequences that are distant in time and space\[15\]\[16\].

Ross Ashby positioned **prose, visualisation, and mathematics** as three complementary representations of system behaviour, moving from intuitive communication to rigorous, unambiguous logic. He viewed them not as competing perspectives, but as different ways of looking at the same underlying reality\[1\]\[2\].

### 1\. Prose: Common Sense and Accessibility

Ashby used prose (natural language) primarily for **essentially common-sense reasoning** and making his work accessible to a wider audience\[3\].

• **The Struggle for Clarity:** Despite being a native speaker, Ashby once put a manuscript aside for over two years to study English more intensively because he felt his knowledge was inadequate for communicating his ideas with the necessary mastery\[4\].

• **Homely Examples:** He was famous for using "homely examples"—such as a kitten finding a warm spot by a fire or a mechanical centipede—to ground abstract concepts in prose that a general reader could grasp\[7\].

• **Book Structure:** He purposefully divided his book _Design for a Brain_ into a non-mathematical prose section (Chapters 1–18) and a mathematical appendix (Chapters 19–22) to cater to different types of readers\[3\].

### 2\. Visualisation: Seeing the "Whole" at a Glance

Ashby used visualizations—such as **kinematic graphs, flow charts, and phase-spaces**—as bridge between prose and mathematics.

• **Intuitive Insight:** He used the **kinematic graph** (a diagram of states connected by arrows) because it is often much easier to follow a point along a line than it is to compute a complex transformation\[10\]\[11\].

• **Frozen Behavior:** The **phase-space** allowed him to show the entire range of a system’s possible trajectories "frozen, as it were, into a single display"\[12\]\[13\].

• **Superior to Algebra for Display:** Ashby noted that visualizations can display properties or prove theses with "the greatest ease, where the algebraic form would have been obscure"\[13\].

### 3\. Mathematics: The "Logic of Mechanism"

Mathematics, specifically **set theory**, was for Ashby the ultimate stage of scientific rigour, used to "vanquish imprecision and vagueness"\[14\]\[15\].

• **Unambiguous Description:** He adopted the set theory of **Bourbaki** because it provided a way to describe relations unambiguously, regardless of whether the variables were numerical or non-metric (like "types of cloud")\[16\].

• **Rigour and Coherence:** He believed that the "rigour and coherence" of his entire general theory of adaptive systems depended on its mathematical form\[3\].

• **The Essence of the "Machine":** Ashby defined a machine not by its material parts, but by its mathematical properties—specifically that its behavior must correspond to a **single-valued mapping**\[20\].

### Synthesis: Two Ways of Looking at the Same Thing

Ashby concluded that **"organization"** and **"mapping"** are essentially the same thing seen through different lenses:

• **Organization** is what is "noticed by the observer of the actual system" (often described in prose or seen in a diagram)\[1\]\[2\].

• **Mapping** is the same behavior "recorded by the person who represents the behavior in mathematical or other symbolism"\[1\]\[2\].

Ashby relied on set theory to describe "non-mathematical" things like cloud types or animal behavior in order to make sense as a way to achieve scientific precision.

Russell Ackoff positioned **prose, visualisation, and mathematics** as complementary perspectives used to model reality, build understanding, and communicate solutions. He categorized these primarily through his framework of **model types** (Iconic, Analogue, and Symbolic) and his focus on the **"Systems Age"** need for both scientific rigor and artistic inspiration.

### 1\. Mathematics: The Representation of Form

Ackoff identified **mathematics** with **symbolic models**, which he described as the most general and abstract form of representation\[1\]\[2\].

• **Abstraction of Form:** Mathematics is the language used to express the **form of experience** once it has been abstracted from its content\[3\]\[4\].

• **Manipulation and Precision:** While difficult to construct, mathematical models are the easiest to manipulate\[1\]\[2\]. They are typically used for **precise final evaluations** and determining "optimal" solutions through algorithms\[5\]\[6\].

• **Limitations:** Ackoff warned that managers often believe quantification is less possible than it is, while management scientists believe it is more possible than it actually is\[1\]. He noted that many strategic and normative decisions cannot be modeled mathematically because they involve complex human choice\[7\]\[8\].

### 2\. Visualisation: Likeness and Comprehensibility

Ackoff linked **visualisation** to **iconic models**, which look like the reality they represent, such as maps, drawings, or flow diagrams\[9\].

• **Comprehensibility:** Visual representations are essential for making a system "comprehensive and comprehensible" to those who control it\[12\]. Ackoff observed that executives are often enlightened when they see a visual representation of the system they manage\[12\].

• **Preliminary Approximations:** He positioned visual/iconic models as **initial approximations** in the research process, which are later refined into more abstract symbolic models\[5\]\[11\].

• **Facilitating Thought:** Representations that look like what they represent facilitate the human thought process\[13\]. Ackoff encouraged the use of "artistic talent" in preparing final versions of these diagrams to increase their impact\[12\].

### 3\. Prose: The Medium for Understanding and Spirit

Ackoff viewed **prose** (or "ordinary English") as the critical vehicle for **understanding**—knowing _why_ a system operates as it does—rather than just having _knowledge_ of how it works\[14\]\[15\].

• **The Test of Understanding:** Ackoff famously argued that technical results are not fully understood by the researcher until they can be explained in **"ordinary English"**\[16\]\[17\]. He believed researchers should be challenged to present their work nontechnically to ensure it is conceptually sound\[17\]\[18\].

• **Scenarios and Narratives:** Prose is the primary medium for the **"reference scenario,"** a detailed, vivid narrative that describes the "mess" an organization faces and reveals the implications of current behavior\[19\].

• **Inspiration and Mission:** He positioned prose as the tool for creating **mission statements** and visions of an **idealized design**\[22\]\[23\]. These narratives provide the "spirit" and "focus" that enable a system's parts to work in harmony\[22\]\[24\].

### The Interaction of the Three

Ackoff advised that these three should be used in **sequence and combination**\[11\]\[25\]. A systems approach typically begins with **prose and visualisation** to formulate the "mess" and define the "containing system," and then moves toward **mathematics** to solve specific tactical problems\[5\]. However, he cautioned against presenting mathematical derivations to managers, suggesting they should remain "available on call" while the primary communication relies on prose and visual aids\[18\]\[29\].

Stafford Beer positioned **prose, visualisation, and mathematics** as an integrated hierarchy of communication and rigour, where **mathematics** serves as the underlying "lingua franca" of systemic laws, **visualisation** acts as a rigorous bridge to human pattern recognition, and **prose** provides the narrative and metalinguistic context necessary for human understanding\[1\].

### 1\. Mathematics: The Lingua Franca of Invariance

Beer viewed **mathematics** as the most powerful language of science, essential for measuring and manipulating complexity\[3\]. He did not regard all models as mathematical, but he used mathematics as a rigorous way to describe **systemic invariance**—the rules that remain constant across different domains, such as the brain and the firm\[4\].

• **Logical Rigour:** He utilised tools like Bourbakian set theory and group theory to provide a formal basis for his models\[8\].

• **Generalisation:** In his "Yo-yo Model," mathematics is the final stage where conceptual models are generalised into a scientific model shorn of "mysticism and poetry"\[11\].

• **Measurement:** Mathematics, statistics, and logic were the three formal languages he used to handle quantity, probability, and quality (relatedness) respectively\[14\].

### 2\. Visualisation: The Bridge to Pattern Recognition

Beer famously transposed his mathematical models into **rigorous diagrams**\[1\]\[9\]. He believed that the human brain is singularly incompetent at handling digits but excels at **pattern recognition** and perceiving relative size, shape, and movement\[17\]\[18\].

• **Valid Representation:** He insisted that diagrammatic rigour was necessary so that the underlying mathematics maintained its validity; he often complained when others "improved" his drawings and destroyed their theoretical basis\[1\].

• **Variety Attenuation:** Iconic representation (visualisation) functions as a **variety attenuator**, suppressing words and numbers to rely on gestalt psychology to convey information directly to the manager\[21\].

• **Accessibility:** Diagrams were intended to "metabolise" science into the world of the manager, making complex mathematical concepts like **recursion** accessible through images like "Russian dolls"\[24\].

### 3\. Prose: Narrative and Metalanguage

Beer treated **prose** as a tool for narrative engagement and logical meta-commentary, though he often found traditional prose formats inadequate for expressing complex systems\[27\].

• **Experimental Format:** In works like _Platform for Change_, he broke sentences into groups and replaced punctuation to "pinpoint ideas" and cut down on verbiage\[28\]\[30\].

• **Metalanguage:** He used prose to establish a **metalanguage**—a language "over and beyond" the operational language—to discuss propositions that are "undecidable" within the system's normal framework\[31\].

• **Humanisation:** He used provocative conversations, such as the "Later in the Bar" sections in his books, to humanise his scientific arguments and foresee common misunderstandings\[35\].

### The Synthesis: The Yo-Yo Model

These three perspectives work together through his **Yo-yo Model** of scientific modelling\[9\]\[38\]. The process begins with an **insight or metaphor** (prose/analogy), moves down into **conceptual models** (prose/visualisation), reduces these into **rigorous formulations** (mathematics/logic), and finally generalises them into an **isomorphic scientific model**\[4\]. The "yo-yo" effect occurs when this rigorous model is then tested against new real-world samples to verify its validity\[4\]\[40\].

Beer used these different perspectives specifically in the design of the **Operations Room** for Project Cybersyn.

Based on the provided texts, T.F.H. Allen positions the representations of prose (specifically **narrative**), **visualization** (images/geometry), and **mathematics** (models) as complementary devices that operate at different levels of abstraction and dimensionality. He argues that while normal science prioritizes mathematical models, complexity science requires the integration of all three, with narrative serving as the overarching framework.

Here is how Allen positions these three perspectives:

### 1\. Mathematics (Models): The Zero-Dimensional State

Allen positions mathematical models as tools for precision, internal consistency, and defining "state," but argues they are insufficient on their own for describing complex systems.

• **Zero-Dimensionality:** Allen defines formal models as "zero-dimensional" points in a parameter space\[1\],\[2\],\[3\]. They represent a fixed "state" of a system\[4\],\[5\].

• **Scale Independence:** Mathematical models (such as the laws of aerodynamics or allometric equations) are scale-independent representations. They function as metaphors that allow scientists to "encode" and "decode" different material systems (e.g., a paper dart and a DC-10) to see if they are analogs of one another\[6\],\[7\],\[8\].

• **Internal Consistency vs. Truth:** Models are praised for being internally consistent, but Allen notes they are "so tightly prescribed that you can think of them as degenerate narratives"\[9\]. He argues that models should serve as "slaves to the narrative," used to calibrate and improve the quality of the story rather than replacing it\[10\],\[11\].

### 2\. Prose (Narrative): The One-Dimensional Copestone

Allen elevates narrative (prose) to the highest position in his epistemological framework, arguing it is the "ultimate product of science"\[11\]. He views narrative not as a lack of rigor, but as a robust device capable of handling the contradictions inherent in complexity.

• **One-Dimensionality:** In contrast to the zero-dimensional model, Allen describes narrative as "one-dimensional" because it possesses a timeline\[12\],\[3\]. It links a series of zero-dimensional models (states) together into a coherent whole\[13\],\[14\].

• **Robustness:** Narratives are more robust than mathematical models because they do not require internal consistency. A narrative can accommodate the contradiction of a system changing its identity over time (e.g., a person being both a "terrorist" and a "freedom fighter" depending on the context), whereas a formal model would fail under such contradiction\[15\],\[16\],\[17\].

• **Scaling Device:** Narrative acts as a "complex scaling device" that transforms rate-dependent processes (dynamics) into rate-independent events, allowing disparate phenomena (like an earthquake and a drought) to be juxtaposed meaningfully\[18\],\[19\].

### 3\. Visualization (Images and Geometry): Structural Types

Allen positions visualization as a critical tool for handling "structural types" and "topology," which often elude algebraic description. He contrasts the static nature of images with the dynamic nature of equations.

• **Templates vs. Functions:** Allen distinguishes between _structural types_ (how parts relate to wholes topologically) and _functional types_ (what the system does). He asserts that "templates can be handled using images... whereas functions tend to be handled using equations"\[20\].

• **Human Processing:** He argues that visualization (such as GIS or graphic representations) utilizes innate human information-processing abilities, making complex data interpretable where tables and graphs might fail\[21\].

• **Geometry over Algebra:** Allen often favors geometric approaches (like fractals or phase space diagrams) over algebraic ones. He suggests that while algebra provides calculation, geometry and topology provide insight into system stability and the nature of space as a context\[22\],\[23\],\[24\]. For example, he notes that projecting a 3-D leaf into a 2-D shadow (visualization) can reveal its "leaf-like" nature in a way that high-dimensional data clouds cannot\[25\].

### Summary of the Relationship

Allen synthesizes these three perspectives into a unified "modeling relation" for complexity:

• **The Narrative** sits above the modeling relation as a "representation of a compression"\[14\],\[26\].

• **The Model (Mathematics)** provides the fixed "state"\[4\].

• **The Visualization (Analogy/Geometry)** allows for the comparison of material systems and the understanding of structural topology\[20\],\[8\].

In Allen's view, "Improving the scientific narrative amounts to insisting that the one-dimensional narrative should pass through the zero-dimensional models"\[3\]. Thus, mathematics tightens the focus, while narrative expands the context, and visualization handles the structural topology\[27\].

This QSet was developed in response to a discussion on LinkedIn [(3) Russell Ackoff - When Optimisation Was No Longer Enough | LinkedIn](https://www.linkedin.com/pulse/russell-ackoff-sheila-damodaran-fsf6f/)which discussed the work of Russ Ackoff.

 In the excellent piece there was a heading "**Coda: Causality and Restraint — Why Ackoff Did Not Diagram**" which warranted further exploration. Ackoff did not match the extreme standards of Geoffrey Vickers which was avowedly 'prose only' but used a few schematic illustrations well and as far as I remember did not rely heavily on Mathematics. In the field of Systems Thinking John Warfield was the strict methodologist who weaved the three representations of prose, visualisation and mathematics in his work (although Postman would suggest there is a fourth, language).

There is much more significance in the use of diagrams and the other members of the representational triad in understanding complexity

It was an ideal candidate for a QSet investigation ...

# Summary

These sources explore how foundational thinkers in systems science and design position **prose, visualization, and mathematics** as a triadic framework for understanding complexity. While **mathematics** provides rigorous abstraction and logical consistency, it is often critiqued for its inability to capture human values or social nuances. **Visualization** acts as a critical bridge, using pattern recognition to translate abstract models into accessible, holistic structures. **Prose** serves as the primary medium for narrative and ethics, though its linear nature can struggle to represent circular systemic relationships. Together, these representations function as a **continuum of inquiry**, where each mode compensates for the cognitive limitations of the others. Ultimately, the sources suggest that mastering complex systems requires a **dialectical balance** between these three distinct languages of thought.
