Claudio Paolucci (Univ. de Bologne) — Séminaire International de Sémiotique à Paris (14/12/2022)

Value of the Information & Strength of the Argument

The value of the information lies in its transdisciplinary synthesis: bridging continental semiotics (Peirce, Eco) with contemporary cognitive science (predictive processing). Paolucci successfully shows that the Bayesian brain hypothesis and Peircean diagrammatic reasoning converge on the idea that perception is an active, imaginative construction. He uses compelling examples (platypus, Marco Polo, the film Blow-Up) to illustrate abstract concepts, making the argument concrete and persuasive. The logical structure is clear: from the problem of unknown phenomena to the role of diagrams as cognitive filters, to the conclusion that perception anticipates the future via imagination. The argumentation is robust and demonstrates a deep understanding of both traditions, though some might find the link between semiotics and neuroscience somewhat speculative.

Scientific Rigor, Source Quality, Title Accuracy

The talk is rigorous in its citation of primary and secondary sources: it references Peirce, Eco, Kant, and Andy Clark explicitly, and also mentions specific experiments (e.g., by Adams and colleagues). The speaker distinguishes his own interpretation from common views, such as the idea that perception is inferential, which he rejects in favor of a diagrammatic-embodied approach. The title is adequate for a seminar announcement, but it does not communicate the specific topic; however, this is not a defect given the format. The overall scientific quality is high, though as a lecture it lacks the peer-review validation of a published paper.

The title accurately identifies the speaker and the seminar series, but does not hint at the content, which focuses on perception, imagination, and diagrams. Neverthless, the title is appropriate for an academic seminar announcement.

8/10

The speaker is a university professor (University of Bologna) presenting a research-informed talk with references to established scholars (Peirce, Eco, Kant, Andy Clark) and uses concrete examples. The talk is expert opinion rather than peer-reviewed, but the argumentation is coherent and well-supported.

Markers derived by PSI from the transcript: the creator did not define chapters.

• 03:00Introduction to main thesis: perception as controlled hallucination and diagrammatic activity.
• 10:00Discussion of Eco's problem of the platypus and the role of prior knowledge in perception.
• 25:00Explanation of predictive coding and Andy Clark's Bayesian brain, linking to semiotic priors.
• 45:00Exploration of diagrams as cognitive filters and their connection to Kant's schematism.
• 1:05:00Conclusion on perception as anticipation of the future and the narrative structure of expectations.

• Charles Sanders Peirce — Peirce's theory of diagrams and perception is central to the talk.
• Umberto Eco — Eco's work on the platypus and semiotics of perception is used to introduce the problem.
• Immanuel Kant — Kant's notion of schema is reinterpreted through Peirce's diagrammatic reasoning.
• Andy Clark — Clark's predictive processing theory provides the cognitive science framework.

• Predictive processing literature (e.g., Clark, 2013) — The talk's claim that perception is a top-down constructive process aligns with predictive processing theories.
