Contribution
From the parts read: the book takes the meaning of linguistic expressions to be conferred by their use, and describes use in normative, not intentional or naturalistic, vocabulary. The norms are deontic statuses (commitment and entitlement) instituted by practitioners’ attitudes of attributing and acknowledging them. Chapter 3 gives the model: assertion’s pragmatic significance is defined in scorekeeping terms, and propositional content as inferential role. The Preface says the model’s building blocks (Kant, Frege, Wittgenstein, Sellars, Dummett, Lewis) are not new; what is claimed new is working the model out in detail and applying it.
Key insight
To say something is to change what you and others are committed and entitled to. A claim’s content is whatever settles how it changes those commitments and entitlements: what it follows from, what follows from it, and what it rules out.
Assumptions
- Normative vocabulary is admissible and ineliminable in specifying use, though it is explained by social practice, not taken as primitive.
- Assertion is the fundamental speech act: questions, orders and promises are intelligible only by their relation to assertions.
- The model is an idealization (“not our actual practice but an artificial idealization of it”): only semantic inferences, and Gricean implicature is left to an outer shell.
- Default and challenge: entitlement is attributed by default unless a challenge is itself entitled.
Key results
The parts read give definitions and arguments, not theorems.
- Assertion (§III.3). It has three parts: undertaking a commitment; authorizing further commitments, one’s own and the audience’s; and a conditional responsibility to vindicate entitlement. Entitlement is inherited by justification (intrapersonal, across contents) and by deferral (interpersonal, within a content).
- Regress (§III.4). Default entitlement and challenges that need their own entitlement dissolve the foundationalist regress.
- Sanction (§III.5). An unentitled assertion loses its inferential and communicational authority; no external sanction is needed.
- Scorekeeping (§IV.1–2). Lewis’s conversational score is recast as deontic score, kept for each interlocutor by each interlocutor. What C is committed to according to A can differ from what C is committed to according to B.
- Score update (§IV.3–4). When B asserts p, scorekeeper A adds p to B’s commitments. A then closes them under commitment-preserving inferences, removes entitlements p’s incompatibilities preclude, adds entitlements by entitlement-preserving inference, and assesses B’s entitlement to p by inference, reliability or testimony. If B is entitled, others may inherit p.
- Other forces (§IV.5). Deferral, disavowal (which, if p follows from q, requires disavowing q), query and challenge attach different force to the same contents.
Method
Philosophical model-building. Requirements on a theory of discursive practice are stated, a simplified game of giving and asking for reasons is specified in scorekeeping terms, and the claim is that the game is sufficient (and in its main structure necessary) to confer propositional content.
Concepts
- commitment / entitlement: the two deontic statuses, the counterparts of obligation and permission without a hierarchy of authority.
- doxastic (assertional) commitment: what an assertion undertakes; the model’s stand-in for belief.
- deontic score: the commitments and entitlements an interlocutor attributes to each participant at a stage of a conversation.
- pragmatic significance: how a speech act depends on, and changes, the score.
- inferential role: a sentence’s place in commitment-preserving and entitlement-preserving inferences and in incompatibilities.
- incompatibility: commitment to one claim precludes entitlement to the other.
Connections
Lewis’s “Scorekeeping in a language game” supplies the score metaphor; Dummett supplies circumstances and consequences of application and the sense/force distinction; Stalnaker’s contrast between the pragmatic and linguistic pictures of intentionality is used to place the view; Davidson’s argument for the interdependence of belief and language is given its form. The early paper “Asserting” (1983), the ancestor of chapter 3, is what Krifka (LIT-835) cites for the commitment theory of assertion. Krifka’s performative update with a speaker’s truth guarantee is close to Brandom’s undertaking of commitment. But Krifka treats declarations and other acts as their own performative updates, whereas Brandom makes assertion fundamental and the other acts parasitic on it.
Bearing on the record
- CLAIM-014 (which changes in conversational standing count). The deontic score is a worked-out answer to “what is a conversational standing”: commitments and entitlements, kept perspectivally. Brandom’s version is per scorekeeper, so it does not supply one objective state for an information order to compare, unless the comparison is made from one scorekeeper’s perspective. Neither this book nor the claim says how to choose that perspective.
- CLAIM-054 (interpretive and performative fidelity come apart). In the parts read, Brandom gives the means to separate what is claimed (content) from what is undertaken and licensed (commitments, entitlements, responsibility to defend). But he derives the second from the first “according to a uniform pattern” plus force, so for him two renderings with the same content and the same force cannot differ in deontic significance. That is a tension with the claim, unless the relational dimensions it names (complicity, solidarity) lie outside the doxastic score, which the parts read do not address.
- No THEORY is filed from a skim. No instruction for ML practice; nothing for the anthology.
Note of 2026-10-16: THEORY-665 now cites LIT-794 as a source.
Limitations
- Skimmed: the arguments for the approach (chapters 1–2), the treatment of practical commitment (chapter 4) and of representation and communication (chapter 8) were not read.
- By the author’s own account the model is an idealization limited to semantic inference.
- Scorekeeping is specified for assertion and its auxiliaries only, in the parts read.
Open questions
- Whether chapter 8’s account of communication across scorekeepers with different collateral commitments (de re ascription) gives a notion of sameness of content across perspectives that a translation could preserve or fail to preserve.
- How practical commitments (chapter 4) extend the score beyond assertion, and whether that reaches the non-doxastic standings (obligations, relationships) Krifka’s performative updates create.
