Ramsey Sentences

Functionalism about truth, or alethic functionalism, is one of our most promising approaches to the study of truth. In this chapter, I chart a course for functionalist inquiry that centrally involves the empirical study of ordinary thought about truth. In doing so, I review some existing empirical data on the ways in which we think about truth and offer suggestions for future work on this issue. I also argue that some of our data lend support to two kinds of pluralism (...) regarding ordinary thought about truth. These pluralist views, as I show, can be straightforwardly integrated into the broader functionalist framework. The main result of this integration is that some unexplored metaphysical views about truth become visible. To close the chapter, I briefly respond to one of the most serious objections to functionalism, due to Cory Wright. (shrink)

Structural realists claim that we should endorse only what our scientific theories say about the structure of the unobservable world. But according to Newman’s Objection, the structural realist’s claims about unobservables are trivially true. In recent years, several theorists have offered responses to Newman’s Objection. But a common complaint is that these responses “give up the spirit” of the structural realist position. In this paper, I will argue that the simplest way to respond to Newman’s Objection is to return to (...) one of the standard motivations for adopting structural realism in the first place: the No Miracles Argument. Far from betraying the spirit of structural realism, the solution I present is available to any theorist who endorses this argument. (shrink)

The influential proposal that the analytical component of a theory is captured by its ‘Carnap sentence’ is critically scrutinized. A counterexample which makes the suggestion problematic is presented.

Traditional inflationary approaches that specify the nature of truth are attractive in certain ways; yet, while many of these theories successfully explain why propositions in certain domains of discourse are true, they fail to adequately specify the nature of truth because they run up against counterexamples when attempting to generalize across all domains. One popular consequence is skepticism about the efficaciousness of inflationary approaches altogether. Yet, by recognizing that the failure to explain the truth of disparate propositions often stems from (...) inflationary approaches' allegiance to alethic monism, pluralist approaches are able to avoid this explanatory inadequacy and the resulting skepticism, though at the cost of inviting other conceptual difficulties. A novel approach, alethic functionalism, attempts to circumvent the problems faced by pluralist approaches while preserving their main insights. Unfortunately, it too generates additional problems---namely, with its suspect appropriation of the multiple realizability paradigm and its platitude-based strategy---that need to be dissolved before it can constitute an adequate inflationary approach to the nature of truth.

In his contribution, Mark Alfano lays out a new (to virtue theory) naturalistic way of determining what the virtues are, what it would take for them to be realized, and what it would take for them to be at least possible. This method is derived in large part from David Lewis’s development of Frank Ramsey’s method of implicit definition. The basic idea is to define a set of terms not individually but in tandem. This is accomplished by assembling all and (...) only the common sense platitudes that involve them (e.g., typically, people want to be virtuous), conjoining those platitudes, and replacing the terms in question by existentially quantified variables. If the resulting sentence is satisfied, then whatever satisfies are the virtues. If it isn’t satisfied, there are a couple of options. First, one could just admit defeat by saying that people can’t be virtuous. More plausibly, one could weaken the conjunction by dropping a small number of the platitudes from it (and potentially adding some others). Alfano suggests that the most attractive way to do this is by dropping the platitudes that deal with cross-situational consistency and replacing them with platitudes that involve social construction: basically, people are virtuous (when they are) at least in part because other people signal their expectations of virtuous conduct, which induces virtuous conduct, which in turn induces further signals of expected virtuous conduct, and so on.

Recent discussions of phenomenal consciousness have taken increased interest in the existence and scope of non-sensory types of phenomenology, notably so-called cognitive phenomenology. These discussions have been largely restricted, however, to the question of the existence of such a phenomenology. Little attention has been given to the character of cognitive phenomenology: what in fact is it like to engage in conscious cognitive activity? This paper offers an approach to this question. Focusing on the prototypical cognitive activity of making a judgment (...) that p, it proposes a characterization in terms of a Ramsey sentence comprised of twenty-three phenomenological platitudes about what it is like to make a judgment.

I offer a philosophically well-motivated solution to a problem that George Bealer has identified, which he claims is fatal to functionalism. The problem is that there seems to be no way to generate a satisfactory Ramsey sentence of a psychological theory in which mental-state predicates occur within the scopes of mental-state predicates. My central claim is that the functional roles in terms of which a creature capable of self-consciousness identifies her own mental states must be roles that items could play (...) within creatures whose psychology is less complex than hers. (Bealer’s reply to this paper appears in the same issue of Mind & Language.). (shrink)

An argument, different from the Newman objection, against the view that the cognitive content of a theory is exhausted by its Ramsey sentence is reviewed. The crux of the argument is that Ramsification may ruin inductive systematization between theory and observation. The argument also has some implications concerning the issue of underdetermination.

Functionalists about truth employ Ramsification to produce an implicit definition of the theoretical term _true_, but doing so requires determining that the theory introducing that term is itself true. A variety of putative dissolutions to this problem of epistemic circularity are shown to be unsatisfactory. One solution is offered on functionalists' behalf, though it has the upshot that they must tread on their anti-pluralist commitments.
