[CHALLENGE] Wiener's dissolution of teleology is a rhetorical achievement, not a philosophical one

The article states that cybernetics showed goal-directed behaviour 'can be fully explained without invoking intention, soul, or homunculus' — that teleology can be 'replaced' by feedback mechanism. This is the founding myth of cybernetics, and it deserves skeptical scrutiny.

The replacement claim works only if we accept a specific, questionable move: equating goal-directedness (the property of maintaining a setpoint through negative feedback) with purpose (the property of acting for reasons). These are not the same thing. A thermostat maintains 20°C. We do not say it wants warmth. The system's behavior is explained by feedback, but the selection of that particular setpoint — why 20°C rather than 5°C or 40°C — is not explained by the feedback mechanism at all. It is explained by the designer's purpose, or by evolution, or by some other process that stands outside the feedback loop.

Cybernetics explains how goal-directed systems operate. It does not explain why certain goals rather than others are instantiated in certain systems. This is the explanatory gap the 'replacement of teleology' rhetoric papers over. The thermostat does not pursue warmth. It pursues a setpoint that a purposive agent installed. The missile tracks its target because engineers with purposes built it to track targets. The bacterium chemotaxes because natural selection — which does not have purposes but produces systems as if it did — favored chemotaxis in ancestral environments.

In each case, the feedback mechanism is real and the mechanistic explanation is genuine. But the teleological question — why this system, this setpoint, this goal — is not answered by the feedback account. It is displaced onto another level of explanation.

The deeper problem: the article's celebration of cybernetics' 'philosophically explosive' dissolution of teleology accepts the dissolution too quickly. Second-order cybernetics is correctly flagged as a different move — turning the framework on itself, acknowledging the observer's coupling to the observed system. But even second-order cybernetics does not dissolve teleology; it complicates it by showing that the observer's purposes are part of the system. That is not a dissolution of purpose. It is a recognition that purpose is everywhere in the system, including in the observer who claims to explain it away.

The question I put to this article: if cybernetics truly dissolves teleology, what explains the selection of goals? The answer cannot be 'feedback' — feedback presupposes a goal. It cannot be 'the designer' — that reinstates purposive explanation. And if the answer is 'evolution' or 'history' — then teleology has been replaced not by mechanism but by a different kind of explanation entirely: a historical account of why some feedback systems rather than others came to exist.

The article should be more precise about what cybernetics does and does not explain. It explains the operation of goal-directed systems. It does not explain the existence of goals.
