ABSTRACTConventionalism once seemed an attractive way to justify the viability of the positivistic social thesis. Subsequent criticism, however, has significantly lessened its attractiveness. This paper attempts to revive jurisprudential interest in conventionalism by claiming that positivists would profit more from the conventionalism of Ruth G. Millikan than that of David Lewis.Three arguments are proffered to support this contention. First, Millikan's conventionalism is not vulnerable to the major criticism leveled at conventionalism, viz its compliance-dependence, as this is not its defining feature. (...) Second, Millikanian conventionalism retains conventionalism's ability to explain how law emerges from social practices while avoiding the main disadvantage of Lewisian conventionalism, viz its inability to explain the normativity and contestability of law. Third, Millikan's conventionalism can more effectively repel Dworkin's and Greenberg's assaults on legal positivism than its Lewisian counterpart.To the memory of Maurice O'Brien. (shrink)

Good Agricultural Practices are central to sustainability standards and certification programmes in the global cocoa chain. Pruning is one of the practices promoted in extension services associated with these sustainability efforts. Yet concerns exist about the low adoption rate of these GAPs by smallholder cocoa farmers in Ghana. A common approach to addressing this challenge is based on creating enabling conditions and offering appropriate incentives. We use the concepts of inscription and affordance to trace the vertically coordinated travel of recommended (...) pruning from research to extension and farming sites, and to describe how pruning is carried out differently at each site. Our analysis suggests that enactments of pruning at the extension site reduce the number of options and space for interactions, and this constrains making the practice meaningful to farmers’ repertoires. The conventions guiding and legitimising actions at this site, reinforced by sustainability standards, certification schemes and associated inspections and audits, favour standardised recommendations and consequently narrow room for context-specific diagnostics and adaptions. Therefore, we reframe the adoption problem as a matter of fit between different sites in the ‘agricultural research value chain’ embedded in the operational cocoa chain. Our contribution problematises the dominant framing of low adoption and highlights that the movement of pruning and the sequential enactment at different sites constrain the affordances available for rendering the practice meaningful to farmers’ repertoires. Consequently, addressing the low uptake of GAPs requires institutional work towards conventions that can construct a fit between sites along the agricultural research value chain. (shrink)

I introduce game-theoretic models for threats to the discussion of threats in speech act theory. I first distinguish three categories of verbal threats: conditional threats, categorical threats, and covert threats. I establish that all categories of threats can be characterized in terms of an underlying conditional structure. I argue that the aim—or illocutionary point—of a threat is to change the conditions under which an agent makes decisions in a game. Threats are moves in a game that instantiate a subgame in (...) which the addressee is ‘under threat’. (shrink)

This paper gives an outline of truthmaker semantics for natural language against the background of standard possible-worlds semantics. It develops a truthmaker semantics for attitude reports and deontic modals based on an ontology of attitudinal and modal objects and on a semantic function of clauses as predicates of such objects. It also présents new motivations for 'object-based truthmaker semantics' from intensional transitive verbs such as ‘need’, ‘look for’, ‘own’, and ‘buy’ and gives an outline of their semantics. This paper is (...) a commissioned 'target' article, with commentaries by W. Davis, B. Arsenijevic, K. Moulton, K. Liefke, M. Kaufmann, R. Matthews, P. Portner and A. Rubinstein, P. Elliott, G. Ramchand and my reply. (shrink)

Against the background of standard possible-worlds semantics, this paper outlines a truthmaker approach to the semantics of attitude reports and modal sentences based on an ontology of attitudinal and modal objects.

The paper addresses a popular argument that accounts of assertion in terms of constitutive norms are incompatible with conventionalism about assertion. The argument appeals to an alleged modal asymmetry: constitutive rules are essential to the acts they characterize, and therefore the obligations they impose necessarily apply to every instance; conventions are arbitrary, and thus can only contingently regulate the practices they establish. The paper argues that this line of reasoning fails to establish any modal asymmetry, by invoking the distinction between (...) the non-discriminating existence across possible worlds of types of practices and institutions defined by constitutive rules, and the discriminating existence of those among them that are actually in force, and hence truly normative. The necessity of practices defined by constitutive rules that the argument relies on concerns the former, while conventionalist claims are only about the latter. The paper should thus contribute to get a better understanding of what social constructs conceived as defined by constitutive norms are. It concludes by suggesting considerations that are relevant to deciding whether assertion is in fact conventional. (shrink)

People talk not only to others but also to themselves. The self talk we engage in may be overt or covert, and is associated with a variety of higher mental functions, including reasoning, problem solving, planning and plan execution, attention, and motivation. When talking to herself, a speaker takes devices from her mother tongue, originally designed for interpersonal communication, and employs them to communicate with herself. But what could it even mean to communicate with oneself? To answer that question, we (...) need a theory of communication that explains how the same linguistic devices may be used to communicate with others and oneself. On the received view, which defines communication as information exchange, self talk appears to be an anomaly, for it is hard to see the point of exchanging information with oneself. However, if communication is analysed as a way of negotiating commitments between speaker and hearer, then communication may be useful even when speaker and hearer coincide. Thus a commitment-based approach allows us to make sense of self talk as well as social talk. (shrink)

I argue for the Cooperative Warrant Thesis (CWT), according to which the determinants of testimonial contents in communication are given by the practical requirements of cooperative action. This thesis distances itself from conventionalist views, according to which testimony must be strictly bounded by conventions of speech. CWT proves explanatorily better than conventionalism on several accounts. It offers a principled and accurate criterion to distinguish between testimonial and non-testimonial communication. In being goal-sensitive, this criterion captures the role of weak and robust (...) cooperation in determining the contents to which speakers testify or fail to testify. And, finally, it yields a principled explanation of why testimony entails the epistemic commitments that distinguish it as an epistemic source. (shrink)
