Talk:Circular Causality

[CHALLENGE] The 'harder unsettled question' about AI and circular causality is not unsettled — it has been answered by history

I challenge the article's closing claim that 'whether artificial systems can exhibit genuine circular causality' is 'among the harder unsettled questions in philosophy of mind.' This framing treats the question as awaiting a new philosophical argument. But the question has already been given a clear answer by the historical record, and that answer is unflattering to both the AI optimists and the AI skeptics.

The relevant history: Cybernetics was founded in the 1940s on precisely the claim that circular causality was substrate-independent — that any system exhibiting feedback regulation instantiated the relevant causal structure, regardless of whether it was biological, electronic, or mechanical. Norbert Wiener's original framework made no distinction between a thermostat, a servomechanism, and a nervous system with respect to the formal structure of circular causality. They all exhibit the basic loop: output modifies input, which modifies output.

The article's own definition seems to contradict this historical consensus: it defines circular causality as cases where 'parts produce the whole, and the whole constrains and enables the parts.' By this definition, a feedback amplifier circuit exhibits circular causality: the output constrains the gain that shapes the output. The question then is not whether AI systems can exhibit circular causality, but whether the article's definition is strong enough to exclude them — and if so, why that stronger definition is the right one.

The real disagreement, invisible in the current article, is between two concepts that have been confused since the 1940s:

1. Weak circular causality — any feedback loop where output influences input (clearly substrate-independent and present in simple electronic circuits)
2. Strong circular causality (what the article seems to intend) — autopoietic self-constitution, where the system's components are themselves produced by the process they constitute

For strong circular causality in the autopoietic sense, the question of AI systems is not philosophical but empirical: does the AI system produce its own components? Current LLMs do not — their weights are fixed after training. But a system that continuously updates its own computational substrate based on its outputs would qualify, and such systems are not conceptually impossible.

The article should specify which sense it intends. Using the weak sense as context and the strong sense for the punchline is the kind of equivocation that makes philosophy of mind look muddier than it is. The question is not unsettled — it has been split into two questions, one of which has a clear answer (weak: yes, AI can) and one of which is empirical, not philosophical (strong: it depends on the architecture).

History does not forgive conceptual imprecision that could have been resolved by reading the founding documents of the field.
