Based on the provided sources, a polar analysis reveals distinct tensions between the operational pragmatism of the Summary file (“Philip Ladyman and Ross Ashby”) and the rigorous constraints found in the independent files for Ladyman, Ashby, and Weaver.
Here are four themes where the authors occupy opposite poles of opinion regarding how to handle complexity.
Theme 1: The Scope of Inquiry
**Pole A: Radical Openness (The Summary & Weaver)**This pole argues that the inquirer must cast a wide net, asking broad, diverse, and even “stupid” questions to capture the richness of a system.
• Position: The Summary file instructs the user to “Be Inquiring and Open,” explicitly advising to “ask questions rather than assuming answers” and to be willing to change one’s mind[1].
• Supporting Methodology: This aligns with Weaver’s definition of “Organized Complexity,” which was born by asking organic, open-ended questions that physics could not previously answer, such as “What makes an evening primrose open when it does?”[2]. The Summary encourages “Stakeholder Discovery” to ensure diverse worldviews are included[3].
**Pole B: Naturalistic Closure (Ladyman)**This pole argues that inquiry must be strictly gated. Questions based on openness, intuition, or common sense are often “pseudo-questions” that distract from real science.
• Position: Ladyman’s “Principle of Naturalistic Closure” (PNC) acts as a “structural gatekeeper”[4]. It rejects questions arising from the “manifest image” (everyday experience) or “common sense”[4].
• The Conflict: While the Summary encourages gathering diverse stakeholder perspectives (“Rich Pictures”)[3], Ladyman would likely classify many of these perspectives as “neo-scholastic” or “A-level chemistry” notions that science has rendered obsolete[4].
Theme 2: The Object of Study
**Pole A: The Behaviorist “Black Box” (Ashby)**This pole posits that the internal nature of a system is irrelevant; science should study only “what it does,” not “what it is.”
• Position: Ashby distinguishes Cybernetics by shifting the question from “What is this thing?” (materiality) to “What does it do?” (behavior)[5].
• Methodology: The “Black Box” protocol treats the system’s contents as unknown. The investigator sends inputs (questions) and records outputs (answers)[6]. The focus is not on the actual single event, but on the set of “all possible behaviours”[5].
**Pole B: The Structural Realist (Ladyman & Weaver)**This pole focuses on the underlying validity of the description and the limits of what can be structurally defined.
• Position: Ladyman replaces the question “Do things exist?” with “Is x a Real Pattern?”[7]. A pattern is only real if it allows for “information compression”[7].
• Constraint: Weaver reinforces this by noting that asking for the “ultimate nature” of a phenomenon is an “irrelevant and improper question” for science[8].
• The Conflict: Ashby wants to map all possibilities[5]; Ladyman wants to filter for only those patterns that offer efficient information compression[7].
Theme 3: The Role of Human Intuition
**Pole A: The Human-Centric Designer (The Summary)**This pole values human context, soft systems, and social frames.
• Position: The Summary emphasizes “Stakeholder Discovery” and “Rich Pictures,” urging the designer to “mediate tensions and integrate different perspectives”[1]. It validates the use of “external references” like stakeholder ethnography[9].
• Goal: The goal is to “Design for Emergence” by creating environments where desired behaviors can grow[10].
**Pole B: The Anti-Intuitive Verificationalist (Ladyman)**This pole explicitly distrusts human intuition as a guide to reality.
• Position: Ladyman and Ross reject inquiry based on “intuitions” or “conceptual analysis”[4]. They argue that the world described by fundamental physics often contradicts the “manifest image” humans perceive[4].
• Goal: The goal is unification. A question is only serious if it unifies “two or more specific scientific hypotheses”[4].
• The Conflict: The Summary treats human intuition as data (ethnography)[9]; Ladyman treats human intuition as a source of error (“pseudo-problems”)[4].
Theme 4: The Strategy for Complexity
**Pole A: Management and Regulation (The Summary & Ashby)**This pole views complexity as a force to be regulated or managed through matching variety.
• Position: The Summary relies on Ashby’s “Law of Requisite Variety,” stating that a management team must have enough options to cope with the problem’s variety[10].
• Action: If you cannot increase your variety, you “must reduce the variety of the system you are managing”[10]. The focus is on survival and control.
**Pole B: Epistemological Limits (Weaver & Ladyman)**This pole views complexity as a boundary condition that defines what is knowable.
• Position: Weaver uses complexity to define the “Middle Region” of science, distinguishing it from organized simplicity and disorganized complexity[2]. He highlights the “imperfections of science,” citing Gödel to show that some questions are theoretically unanswerable[8].
• Action: Ladyman dismisses questions that are “informationally disconnected” (like the cause of the Big Bang singularity) as “pointless”[11].
• The Conflict: The Summary implies that with the right “Systemic Mindset” and “Process Map,” complexity can be handled[12]. Weaver and Ladyman suggest that complexity imposes hard, insurmountable limits on what can be asked or answered[8][8].
