Summary

In this first Pufendorf Lecture, Robert Brandom explores the relationship between pragmatics and semantics, focusing on how discursive practices confer propositional content on linguistic expressions. He introduces the conferral and codification conditions as criteria of adequacy for a pragmatic theory. Brandom discusses the act-content distinction, the force-content distinction, and the role of norms in governing linguistic practice. He draws on the work of Wilfrid Sellars and Gilbert Harman to argue that reasoning practices are central to understanding assertion and denial. Brandom then presents a bilateral model of discursive practice, based on the work of Restall and Ripley, which understands implication and incompatibility in terms of normative assessments of commitments to accept and reject. He connects this to Kit Fine’s truthmaker semantics, suggesting an isomorphism between the normative structure of reasoning and the metaphysical structure of truthmaking. The lecture sets the stage for subsequent lectures on the rational functional role of propositional content.

Critical Evaluation

Value of the Information & Strength of the Argument

The lecture provides a high-value, rigorous philosophical argument. Brandom systematically develops a framework for understanding the relation between pragmatics and semantics, offering clear criteria of adequacy and building a detailed model. The argumentation is solid, drawing on historical and contemporary sources, and is presented in a coherent, step-by-step manner. The discussion of the bilateral model and its connection to truthmaker semantics is particularly insightful, offering a novel perspective on how meaning and use are related.

Scientific Rigor, Source Quality, Title Accuracy

The lecture demonstrates high scientific rigor, with careful definitions and clear argumentation. Brandom engages with key figures in the analytic tradition (Frege, Wittgenstein, Sellars, Harman, Restall, Ripley, Fine) and provides a full text online for verification. The title accurately reflects the content, focusing on reasoning and representing as central to the series. The lecture is well-structured and the sources are appropriately cited, though the video description only provides a link to the full text, not to individual sources.

Contribution & Novelties

This lecture offers a novel synthesis of inferentialist pragmatics and truthmaker semantics, proposing an isomorphism between normative reason relations and metaphysical truthmaking relations. It develops a bilateral model of discursive practice that respects Harman’s insight about the gap between implication and reasoning. The lecture is part of a larger project to provide a new account of the rational functional role of propositional content.
