A very strong candidate for that role is Karl Jaspers.
Referencing Jaspers helps close the theoretical arc because his work sits precisely at the intersection of psychiatry, epistemology, and the philosophy of science. Although he wrote decades before cybernetics or predictive processing, his analysis of knowledge, interpretation, and understanding in psychiatry anticipates many themes that appear in the present framework.
Below is a way you could incorporate him into the paper.
Karl Jaspers and the Epistemology of Psychiatry
Karl Jaspers’ General Psychopathology (1913/1963) established one of the most influential philosophical foundations for modern psychiatry. Jaspers emphasized that psychiatric knowledge requires a careful distinction between explanation (Erklären) and understanding (Verstehen). While explanation seeks causal mechanisms, understanding concerns the interpretation of subjective meaning within human experience.
Crucially, Jaspers argued that psychiatric knowledge must remain methodologically self-critical, continually revising its interpretations in light of new evidence and perspectives. He warned against rigid theoretical systems that claim complete explanatory authority and emphasized the provisional status of psychiatric knowledge.
From the perspective proposed in the present paper, Jaspers can be interpreted as anticipating an important feature of error-correcting intelligence: epistemic humility and revisability. Psychiatric theories must remain open to correction because they concern complex systems in which multiple levels of explanation interact.
Jaspers as a Bridge Figure
Including Jaspers helps situate the present framework within the intellectual history of psychiatry.
Whereas cybernetics and predictive processing describe how adaptive systems correct error, Jaspers addressed the epistemological conditions under which psychiatric knowledge can remain open to correction.
In this sense, his work can be understood as identifying the importance of institutionalized critical reflection within psychiatry.
This resonates with the broader argument of the present paper: that intelligence emerges where systems develop procedures that allow errors in their models to be detected and revised.
Extending the Historical Lineage
With Jaspers included, the theoretical lineage becomes:
Darwin → Wiener → Ashby → Bateson → Popper → Jaspers → Friston → AI → Psychotherapy
Each thinker contributes a key component:
| Thinker | Contribution |
|---|---|
| Darwin | adaptation through selection |
| Wiener | feedback systems |
| Ashby | regulation and requisite variety |
| Bateson | learning and communication systems |
| Popper | epistemic error correction |
| Jaspers | critical epistemology in psychiatry |
| Friston | predictive processing and active inference |
| AI research | algorithmic learning |
| Psychotherapy | revision of personal models |

For example in the discussion:
This perspective also resonates with Karl Jaspers’ epistemological approach to psychiatry, which emphasized the provisional and revisable nature of psychiatric knowledge (Jaspers, 1963). Jaspers’ insistence that psychiatric understanding must remain open to correction anticipates contemporary views that adaptive cognition depends on the capacity to revise internal models in response to new evidence.
By including Jaspers, the paper shows that its central idea—knowledge systems must remain corrigible—is not only a feature of modern computational theories but also deeply rooted in the philosophical foundations of psychiatry.
This helps close the theoretical arc from biological adaptation to epistemic humility in clinical practice.
