Performatives and Contingent A Priori Truths - A Talk by Marco Ruffino (part I)

Value of the Information & Strength of the Argument

The talk offers a valuable perspective by connecting Kripke’s examples to speech act theory, which is a novel and insightful approach. Ruffino’s argument is well-structured: he first presents Kripke’s examples, then introduces Austin’s performatives and Searle’s taxonomy, and finally applies this framework to the examples. He addresses potential objections and provides a concrete illustration with the kilogram redefinition. However, the argument is not fully developed; it is presented as a research project in progress, and some steps are asserted rather than rigorously defended. The discussion of authority and institutional backing is suggestive but could be more detailed.

Scientific Rigor, Source Quality, Title Accuracy

Ruffino demonstrates familiarity with key literature: Kripke’s ‘Naming and Necessity’, Austin’s ‘How to Do Things with Words’, Searle and Vanderveken’s ‘Foundations of Illocutionary Logic’, and papers by Dummett, Donnellan, and Horowitz. He accurately represents these sources. The title is appropriate, though it might be more specific about the speech act approach. The talk is an expert opinion, not a peer-reviewed study, so its rigor is moderate. No comments were provided for analysis.

The title accurately reflects the content: the talk focuses on performatives and the contingent a priori, as part of a series.

7/10

The talk is a scholarly presentation by a philosophy professor, engaging with established literature (Kripke, Austin, Searle, etc.) and offering a novel perspective. However, it is an opinion/expert talk without peer review or empirical data, and the argument is presented as a proposal rather than a fully developed thesis.

• Naming and Necessity — Kripke's book introducing the examples of the meter stick and Neptune.
• How to Do Things with Words — Austin's lectures on performative utterances.
• Foundations of Illocutionary Logic — Searle and Vanderveken's work on speech acts.
• Reference and Definite Descriptions — Donnellan's paper criticizing Kripke's examples.
• The Contingent A Priori: A Reply to Kripke — Horowitz's paper raising objections.

• Naming and Necessity — Kripke's original work supports the existence of contingent a priori truths.
• How to Do Things with Words — Austin's theory of performatives underpins the proposed interpretation.

• Reference and Definite Descriptions — Donnellan argues that stipulation cannot create contingent truths, contradicting Ruffino's proposal.
• The Contingent A Priori: A Reply to Kripke — Horowitz claims that empirical knowledge is required for stipulations to work, undermining the a priori status.
