Hartry Field has proposed a fundamental division of theories of linguistic and mental content into those that do, and those that don’t, give a central role to ‘that’-clause ascriptions. Here I investigate the commitments of theories that (in accord with Field’s position) deny ‘that’-clause ascriptions a central role, but (in contrast to Field’s position) give truth conditions a central role. Such non-oblique truth-conditionalism promises significant advantages. However, the stance is costlier than it may appear. Non-oblique truth-conditionalists, I argue, must renounce (...) a priori entitlement to schemas of disquotation that are presupposed when theories of content are put to metaphysical or epistemological use. As case studies, I discuss two theories that might seem to exemplify non-oblique truth-conditionalism: David Chalmers’s two-dimensionalist theory of content and Ruth Millikan’s teleosemantics.

This paper employs Ruth Millikan’s biosemantic theory of representation to develop a proposal about the function of ethical claims and judgments. I propose that ethical claims and judgments (or ethical ‘affirmations’) have the function of simultaneously tracking the morally salient features of social situations and directing behavior that coordinates in a collectively beneficial way around those features. Thus, ethical affirmations count as a species of what Millikan labels ‘Pushmi-Pullyu’ representations that simultaneously have a descriptive and a directive direction of fit. (...) This proposal supports a version of motivational internalism that can accommodate a surprising range of actual failures of motivation. I also briefly situate this proposal in the metaethical literature, contrasting it with other hybrid views incorporating elements of cognitivism and expressivism. (shrink)

A central idea in Ruth Millikan’s biosemantics is that a representation’s content is restricted to conditions required for the normal success of actions that it has as its function to guide. This paper raises and responds to a problem for this idea. The problem is that the success requirement seems to block us from saying that epistemic modal judgments represent our epistemic circumstances. For the normal success of actions guided by these judgments seems to depend on what is actually the (...) case, not on whether or to what extent various possibilities were supported by our evidence. In response, I argue, first, that actions guided by epistemic modal judgments have as their function to implement strategies for handling epistemic circumstances, second, that the successful performance of this function requires that aspects of these circumstances obtain, and, third, that biosemantics can thus understand epistemic modal judgments as representing these aspects. The recognition of such strategic contents introduces complications; I further argue that these are benign. (shrink)

“Teleosemantic” or “biosemantic” theories form a strong naturalistic programme in the philosophy of mind and language. They seek to explain the nature of mind and language by recourse to a natural history of “proper functions” as selected-for effects of language- and thought-producing mechanisms. However, they remain vague with respect to the nature of the proposed analogy between selected-for effects on the biological level and phenomena that are not strictly biological, such as reproducible linguistic and cultural forms. This essay critically explores (...) various interpretations of this analogy. It suggests that these interpretations can be explicated by contrasting adaptationist with pluralist readings of the evolutionary concept of adaptation. Among the possible interpretations of the relations between biological adaptations and their analogues in language and culture, the two most relevant are a linear, hierarchical, signalling-based model that takes its cues from the evolution of co-operation and joint intentionality and a mutualistic, pluralist model that takes its cues from mimesis and symbolism in the evolution of human communication. Arguing for the merits of the mutualistic model, the present analysis indicates a path towards an evolutionary pluralist version of biosemantics that will align with theories of cognition as being environmentally “scaffolded”. Language and other cultural forms are partly independent reproducible structures that acquire proper functions of their own while being integrated with organism-based cognitive traits in co-evolutionary fashion.
