Valeria De Luca (Université de Limoges) — Séminaire International de Sémiotique à Paris (8/03/2023)

Value of the Information & Strength of the Argument

The talk provides significant value by proposing an innovative interdisciplinary framework that merges mathematical morphology and dance semiotics. The argumentation is coherent and well-structured, systematically connecting abstract notions to concrete examples. De Luca demonstrates deep familiarity with both Thom and Laban’s work, and she critically engages with secondary literature. However, she openly acknowledges that some connections are exploratory and that definitive answers remain open, which adds intellectual honesty. The presentation effectively supports the claim that a continuous, dynamic model is necessary to account for the emergence of forms in dance, and it convincingly argues for the relevance of these concepts to cultural heritage projects.

Scientific Rigor, Source Quality, Title Accuracy

The scientific rigor is generally high: the speaker is a specialist, she situates her work within established scholarly debates, and she explicitly cites key authors such as Thom, Laban, Pouillaude, and Viret. Yet detailed references (exact books or articles) are not provided, and some arguments rely on personal interpretations. The title is accurate but not descriptive: it names the speaker and event, leaving the topic unspecified. This is common for seminar announcements but does not affect the content’s quality.

The title accurately identifies the speaker and the event, but it does not convey the specific content about the intersection of geometry, semiotics, and dance.

7/10

The talk is a scholarly presentation from a recognized researcher in semiotics, drawing on established theories and recent scholarship. However, most references are mentioned verbally without detailed citations, and some claims are exploratory.

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

• 01:00Introduction of Valeria De Luca by the seminar chair, outlining her research background.
• 10:00De Luca poses the central question of whether space pre-exists or emerges with form, linking Gestalt and discontinuity.
• 20:00Discussion of Thom’s idea of dance as morphogenetic activity and the use of fluid dynamics models.
• 30:00Explanation of Laban's kinesphere and dynamosphere, with sketches and examples.
• 40:00Analysis of effort theory and the combination of factors to describe movement qualities.
• 50:00Conclusion: synthesis of Thom and Laban for a semiotic approach to dance, and illustration with dancer portraits.
• 1:00:00Thank-yous and brief comments from the audience.

• Apologie du Logos (René Thom) — Referenced as the work where Thom treats dance as a morphogenetic activity.
• Laban’s writings on dance notation and effort — Mentioned as the foundation of the kinesphere and dynamosphere concepts.
• Laurence Louppe – Interview with René Thom (1991) — Cited as a text where Thom explicitly relates dance to fluid dynamics and kinesphere.
• Jacques Viret (2018) – Comparative study on Jung and Laban — Reported to establish historical connections between Laban and Jung.
• Frédéric Pouillaude – Le Désœuvrement chorégraphique — Discussed regarding the non-identity of dance works and the limits of notation.
