Observer and recognition

Observer and recognition

“A system is not something given in nature, but something defined by intelligence” (DC 1966: 242). Coherence, pattern and purpose “are, all three, acts of mental recognition rather than characteristics of physical things” (DC 1966: 243). 1980: “A system is not something presented to the observer, it is something recognized by him” (TBYT 2009, “Preface to Autopoiesis”: 68).

What Beer says

“To speak of a system is to speak of the coherence of a number of entities called parts of that system” (DC 1966: 241). A collection “is not dignified by the unitary notion of a system until some unifying purpose is devised for it” (DC 1966: 242). Recognition “is precisely the formulation of a conceptual model of system” (DC 1966: 246). Existence cannot be proved; only that the treatment is “helpful” (DC 1966: 243). Relatively isolated system: separable except for chosen inputs and outputs (DC 1966: 273). Definition “depends on who is the observer” (DC 1966: 274); for control, closure is “artificial” (DC 1966: 288). Variety depends “on who defines it” (DC 1966: 247). Ashby: “only variety can destroy variety” (DC 1966: 279). A viable system absorbs variety “like a sponge” (DC 1966: 284, 293). The black box is a variety resource (DC 1966: 293–296).

Where it sits in the model

System-in-focus is an observer’s cut (Recursion). Measured variety is observer-relative (Variety and regulation). Recognition is model-making (Homomorphism; DC 1966: 246).

Textual notes

1966 “defined by intelligence” (DC 1966: 242) vs 1980 “not something presented to the observer” (TBYT 2009: 68). Variety sponge in DC later names the Three–Four exchange monitored by System Five (HOE 1979: 144) (Pure VSM — Appendix).

Punch and Judy

Punch and Judy (Mathis and Heath, v0.5.0 draft) takes up Beer’s observer claim and argues it names, but does not proceduralise, the most consequential act in an engagement: naming the system, drawing its boundary and choosing the System-in-focus are treated as given, and no procedure exposes the analyst’s choice to a second reader (Coda; Chs 5–6). It reads Ulrich’s, Hayek’s and Cooper’s published objections as one wound about that first act, and reports that Beer named the observer’s act, made it the workbook’s first task and revised one boundary in print, but supplied no procedure (Ch 16). Chapter 19 records a further charge, marked the authors’ own and possibly wrong, that “the model is viable” slides between Beer’s sense and the constructivist sense in which a claim is viable when useful.
