# Pathologies of viable systems

Breakdowns trace to "malfunction in one of the five subsystems," where a cybernetic rule "will be found not to be functioning" (TBYT 2009, "The Viable System Model": 147–148). Being there ≠ viable: "effectively there, witness universities, nor efficiently there, witness hospitals" (TBYT 2009: 148).

## What Beer says

- **Repeal of requisite variety** — people "attempt to repeal the Law of Requisite Variety itself" (TBYT 2009: 148).
- **Takeovers** — promised autonomy "is poppycock"; the [Law of Cohesion](https://wiki.cybernetic-futures.org/pure-vsm/concepts/law-of-cohesion) shows the new recursion takes variety from the subsidiary (TBYT 2009: 149).
- **Identity** — "Will the system still be able to recognize itself? More particularly, will others be able to recognize it?" (TBYT 2009: 149).
- **[Four](https://wiki.cybernetic-futures.org/pure-vsm/concepts/system-four) missing** — "usually, virtually empty"; "the whole metasystem collapses into System Three" (HOE 1979: 265).
- **Five into Three** — they "dive down into the problem that they understand so well—never to emerge again." "The collapsed metasystem is a special pathology. It is a decerebrate cat" (TBYT 2009: 150). Same dive "straight into System Three, or (worse) straight into a muddy bog in System One" (HOE 1979: 266).
- **Pathological autopoiesis** — "turn self-production into an end-in-itself" (HOE 1979: 410). Healthy autopoiesis is only [System One](https://wiki.cybernetic-futures.org/pure-vsm/concepts/system-one); Two–Five should "exhibit no internal autopoietic behaviour whatever." When they do: "**The Establishment**" (HOE 1979: 412).
- **Ultimate** — "failure of its cohesiveness, and of its inter-recursive algedonics" as "an aberration of its autopoietic function" (HOE 1979: 408).

## Where it sits in the model

[Diagnosing the System for Organizations](https://wiki.cybernetic-futures.org/pure-vsm/entities/diagnosing-the-system-for-organizations) against the five subsystems and the [Principles and axioms of organization](https://wiki.cybernetic-futures.org/pure-vsm/concepts/principles-and-axioms-of-organization). Cohesion and [algedonics](https://wiki.cybernetic-futures.org/pure-vsm/concepts/algedonic-signal) fail together.

## Textual notes

Four diagnostic points quoted from "a learned journal," endorsed not originated (TBYT 2009: 148–149). Establishment definition prints "vital principal [sic]" (HOE 1979: 412).

## Punch and Judy

Punch and Judy argues that the pathology catalogue, treated as prediction, has never been tested and cannot easily be: being generated from the model rather than collected from a case library, it always has a name ready for whatever happened (Ch 24), and the chapter on the category-error shelter lists the catalogue as prediction among the claims a purely performative reading would have to withdraw (Ch 21). Its related charge is that the community's unbroken record — that nobody has found a case where the model failed — describes how the field records its work rather than the model itself (Ch 17; Ch 18). These are the manuscript's arguments, several provisional, not findings against Beer.

## Open points

Journal of the four points: *Brain and Strategy* 4(9) 1978 (TBYT 2009: 157 n.15); author/title unidentified. HOE's "Identity: an exercise" later called "Test of Identity" (TBYT 2009: 150) — HOE does not use that name. Draft not canon ([Pure VSM — Overview](https://wiki.cybernetic-futures.org/pure-vsm/overview)).
