Geach is best known for his contributions to theoretical philosophy: Most of his more than one hundred papers and a dozen books are on logic, philosophy of language and metaphysics. But he also made significant contributions to ethics. Particularly influential were a series of short metaethics papers, which are small masterpieces, both in terms of philosophical content and style. In usually less than ten pages, Geach delivers sharp analyses and powerful objections against influential schools. His arguments are always (...) so clear and his examples so simple that they leave the reader wondering why no one before Geach detected the problems he points out. (shrink)

In his celebrated 'Good and Evil' (l956) Professor Geach argues as against the non-naturalists that ‘good’ is attributive and that the predicative 'good', as used by Moore, is senseless.. 'Good' when properly used is attributive. 'There is no such thing as being just good or bad, [that is, no predicative 'good'] there is only being a good or bad so and so'. On the other hand, Geach insists, as against non-cognitivists, that good-judgments are entirely 'descriptive'. By a consideration (...) of what it is to be an A, we can determine what it is to be a good A, even where the ‘A’ in question is ‘human being’. These battles are fought on behalf of naturalism, indeed, of an up-to-date Aristotelianism. Geach plans to 'pass' from the 'purely descriptive' man to good/bad man, and from human act to good/bad human act. I argue: (l) That the predicative 'good' does have a genuine sense and that it is a mistake to suppose that ‘good’ is a purely attributive adjective. This does not entail that the predicative good (as used by Moore) denotes a non-natural property, but his mistake, if any is metaphysical or ontological not conceptual. (2) That the attributive 'good' cannot be used to generate a naturalistic ethic. It is difficult to extract a set of biologically based requirements out of human nature that are a) reasonably specific; b) rationally binding or at least highly persuasive; and c) morally credible. -/- On the way I protest against Geach’s tendency to try to win arguments by affecting not to understand things. -/- My views to some extent anticipate those of Kraut in *Against Absolute Goodness*.

This is an opinionated overview of the Frege-Geach problem, in both its historical and contemporary guises. Covers Higher-order Attitude approaches, Tree-tying, Gibbard-style solutions, and Schroeder's recent A-type expressivist solution.

Aquinas’ theory of being has received a growing amount of attention from contemporary scholars, both from a historic and a philosophical point of view. An important source of this attention is Geach’s seminal Form and Existence. In it, Geach argues that Aquinas subscribes to a tensed notion of existence and a theory of time according to which past and future entities do not exist in act. Subsequent commentators, such as Kenny in his Aquinas on Being, have agreed with (...) Geach on both points. In this paper, I argue that in several passages of his corpus, most notably those in which he is concerned with God’s knowledge of future contingents, Aquinas implicitly subscribes to a theory of being and time according to which: past and future entities are attributed existence in act, there is theoretical need for introducing a tenseless notion of existence.

In the 1960s, Peter Geach and John Searle independently posed an important objection to the wide class of 'noncognitivist' metaethical views that had at that time been dominant and widely defended for a quarter of a century. The problems raised by that objection have come to be known in the literature as the Frege-Geach Problem, because of Geach's attribution of the objection to Frege's distinction between content and assertoric force, and the problem has since occupied a great (...) deal of the attention both of defenders of broadly noncognitivist views, and of their critics. In this article I explain Geach and Searle's historical objections, and put the subsequent discussion into dialectical context, paying some attention to the developments along the way and how they have enhanced our overall understanding of the problem. The article covers a lot of territory, so we will only be able to see the highlights, along the way. For further reading, see the Works Cited. (shrink)

This paper discusses the first incarnation of what came to be known as the “Frege-Geach” point. The point was made by Peter Geach in his 1960 essay “Ascriptivism”, and developed in “Assertion”, a 1965 piece. Geach’s articles launch a wholesale attack on theories of non-descriptive performances advanced by “some Oxford philosophers” whom he accuses of ignoring “the distinction between calling a thing ‘P’ and predicating ‘P’ of a thing”. One view that Geach specifically targets is H. (...) L. A. Hart’s claim that sentences of the form “X φ-ed” are not primarily descriptive but ascriptive of responsibility for actions. Hart explicitly accepted Geach’s criticism, and disowned his essay. I argue that he was wrong to do so. Perhaps the essay was worth retracting, but not because of Geach’s objections. I begin by restating and refining Geach’s arguments, in order to bring out the flaw he claimed to have detected in the “pattern of philosophising” that he took Hart’s essay to exemplify. I go on to argue that Geach’s original point poses no obstacle either to non-descriptivism in general, or to Hart’s sui generis non-descriptivist claim in particular. (shrink)

According to judgment internalism, there is a conceptual connection between moral judgment and motivation. This paper offers an argument against that kind of internalism that does not involve counterexamples of the amoralist sort. Instead, it is argued that these forms of judgment internalism fall prey to a Frege-Geach type argument.

Several philosophers have recently appealed to predication in developing their theories of cognitive representation and propositions. One central point of difference between them is whether they take predication to be forceful or neutral and whether they take the most basic cognitive representational act to be judging or entertaining. Both views are supported by powerful reasons and both face problems. Many think that predication must be forceful if it is to explain representation. However, the standard ways of implementing the idea give (...) rise to the Frege-Geach problem. Others think that predication must be neutral, if we’re to avoid the Frege-Geach problem. However, it looks like nothing neutral can explain representation. In this paper I present a third view, one which respects the powerful reasons while avoiding the problems. On this view predication is forceful and can thus explain representation, but the idea is implemented in a novel way, avoiding the Frege-Geach problem. The key is to make sense of the notion of grasping a proposition as an objectual act where the object is a proposition. (shrink)

Dies bietet einen knappen Überblick über Leben und Werk des britischen Philosophen P. T. Geach. Unter anderem wird vorgeführt, mithilfe welches Arguments Geach die Sein/Sollen-Schranke zu überwinden beanspruchte.

According to the established understanding of the Frege-Geach problem, it is a challenge exclusively for metaethical expressivism. In this paper, I argue that it is much wider in scope: The problem applies generally to views according to which moral sentences express moral judgments entailing that one is for or against something, irrespective of what mental states the judgments consist in. In particular, it applies to motivational internalism about moral judgments. Most noteworthy, it applies to cognitivist internalism according to which (...) moral judgments consist in motivating beliefs. Hence, in order for a metaethical view to evade the Frege-Geach problem, it should avoid stating that moral judgments are motivating. (shrink)

Hybrid expressivists claim to solve the Frege-Geach problem by offloading the explanation of the logico-semantic properties of moral sentences onto beliefs that are components of hybrid states they express. We argue that this strategy is undermined by one of hybrid expressivism’s own commitments: that the truth of the belief-component is neither necessary nor sufficient for the truth of the hybrid state it composes. We articulate a new approach. Instead of explaining head-on what it is for, say, a pair of (...) moral sentences to be inconsistent, expressivists should “sidestep” and explain what it is _to think that_ a pair of moral sentences is inconsistent. To think so is to think they cannot both be true – a modal notion. Since expressivists have given accounts of such modals, we illustrate how sentences like ‘“lying is wrong” and “lying is not wrong” are inconsistent’ express sensible – and rationally compelling – states of mind.

Sven Rosenkranz’s Justification as Ignorance shows how a strongly internalist conception of justification can be derived from a strongly externalist conception of knowledge, given an identification of justification with second-order ignorance and a set of structural principles concerning knowing and being in a position to know. Among these principles is an epistemic analogue of the Geach modal schema which states that one is always in a position to know that one doesn’t know p or in a position to know (...) that one doesn’t know not-p. Even suitably refined, the principle faces a range of counterexamples in which it misleadingly and persistently seems to one that one knows whether p without it seeming to one that one knows p nor that one knows not-p. These cases also threaten the book’s case for the luminosity of second-order ignorance, which is in turn central to its derivation of strongly internalist principles of justification. (shrink)

Según varios filósofos del lenguaje contemporáneos, el argumento Frege-Geach plantea una objeción genuina para el expresivismo semántico. En el presente texto se sostiene que una manera eficaz de enfrentar y superar este argumento es modificando la concepción expresivista clásica. Se examinan el expresivismo clásico y el expresivismo mínimo y se propone una versión de este último que, a la vez que supera la objeción derivada del argumento Frege-Geach, tiene la ventaja de incluir dentro del espectro del expresivismo teorías (...) que claramente tienen este “espíritu” pero que la caracterización clásica deja fuera.

I resolve the major challenge to an Expressivist theory of the meaning of normative discourse: the Frege–Geach Problem. Drawing on considerations from the semantics of directive language (e.g., imperatives), I argue that, although certain forms of Expressivism (like Gibbard’s) do run into at least one version of the Problem, it is reasonably clear that there is a version of Expressivism that does not.

I follow the distinction of predicative versus attributive adjectives introduced by P.T. Geach in 1956 and discuss Atina Knowles' arguments contra the revisions of Geach's original conception.

Despite its many advantages as a metaethical theory, moral expressivism faces difficulties as a semantic theory of the meaning of moral claims, an issue underscored by the notorious Frege-Geach problem. I consider a distinct metaethical view, inferentialism, which like expressivism rejects a representational account of meaning, but unlike expressivism explains meaning in terms of inferential role instead of expressive function. Drawing on Michael Williams’ recent work on inferential theories of meaning, I argue that an appropriate understanding of the pragmatic (...) role of moral discourse—the facilitation of coordinated social behavior—suggests the kind of inferences we should expect terms with this function to license. I offer a sketch of the inferential roles the moral ‘ought’ plays, and argue that if we accept that the relevant inferential roles are meaning-constitutive, we will be in a position to solve the Frege-Geach problem. Such an inferentialist solution has advantages over those forwarded by expressivists such as Blackburn and Gibbard. First, it offers a more straightforward explanation of the meaning of moral terms. It also gives simple answers to at least two semantic worries that have vexed contemporary expressivists—the “problem of permissions” and the commitment to “mentalism”, both of which I argue are problems that don’t get traction with an inferentialist approach. I conclude by considering ways in which this approach can be expanded into a more robust semantic account. (shrink)

Mark Eli Kalderon has argued for a fictionalist variant of non-cognitivism. On his view, what the Frege–Geach problem shows is that standard non-cognitivism proceeds uncritically from claims about use to claims about meaning; if non-cognitivism's claims were solely about use it would be on safe ground as far as the Frege–Geach problem is concerned. I argue that Kalderon's diagnosis is mistaken: the problem concerns the non-cognitivist's account of the use of moral sentences too.

The problem of identity is central to epistemic transference. However, relative identity appears to be the only way to work out an epistemic useful notion of identity. Relative identity, on its part, is either parasitic on strict identity or not identity at all. If, on the contrary, we ought for a strict concept of identity capable of satisfying its requirements, we end up with a tautologic and epistemic worthless category. The paper provides an answer to this problem, which, while working (...) with a strict notion, shows how it might still serve epistemic purposes. In doing so, it shows how a formal reconstruction of our objectual world and the identities we refer to poses a workable model upon which our messy epistemic one acquires stability. The paper focuses primarily on the Geach-Quine discussion on identity. (shrink)

Our question, in this paper, is about the plausibility of the expressivist account of one’s self- attribution of mental states. More to the point, we will strictly follow the principle of charity as a mean to show that an expressivist philosopher can have good and reasonable answers to the set of objections put together in so called “Geach’s point”. Using this method, we hope to give enough evidences that an expressivist philosopher has enough resources to build a plausible explanation (...) for one’s attribution of mental states to herself.

A short review of the collection of Anscombe's ethical essays edited by Mary Geach and Luke Gormally.

Peter Geach’s distinction between logically predicative and logically attributive adjectives has gained a certain currency in philosophy. For all that, no satisfactory explanation of what an attributive adjective is has yet been provided. We argue that Geach’s discussion suggests two different ways of understanding the notion. According to one, an adjective is attributive just in case predications of it in combination with a noun fail to behave in inferences like a logical conjunction of two separate predications. According to (...) the other, an adjective is attributive just in case it cannot be applied in a truth-value-yielding fashion unless combined with a noun. The latter way of understanding the notion has been largely neglected by Geach’s critics, but we argue that taking account of it shows the misguided nature of some of their objections, and also yields a more satisfactory explanation of attributivity than does the other. (shrink)

Geach and Thomson have argued that nothing is just plain good, because ‘good’ is, logically, an attributive adjective. The upshot, according to Geach and Thomson, is that consequentialism is unacceptable, since its very formulation requires a predicative use of ‘good’. Reactions to the argument have, for the most part, been uniform. Authors have converged on two challenging objections . First, although the logical tests that Geach and Thomson invoke clearly illustrate that ‘good’, as commonly used, is an (...) attributive, they don’t show that ‘good’ lacks an intelligible predicative interpretation. Second, even if the English word ‘good’ fails to express the property of goodness, we can just stipulate that ‘good*’ expresses goodness and thus formulate consequentialism accordingly. The second objection is one way of voicing skepticism about the method of drawing substantive philosophical conclusions from considerations about ordinary language. In this essay, we present an argument, inspired by Geach and Thomson, which isn’t susceptible to the same objections but which supports the same conclusion. The significance of our argument for ethics is obvious; it challenges the intelligibility of standard consequentialism, and even certain forms of non-consequentialism. One might be inclined to think that a more sophisticated consequentialism, which relies on ‘good {possible world/state of affairs/outcome}’ instead of just ‘good’, evades the criticism. But we explain why the criticism can’t be so easily evaded. (shrink)

Frege-Geach worries about embedding and composition have plagued metaethical theories like emotivism, prescriptivism and expressivism. The sharpened point of such criticism has come to focus on whether negation and inconsistency have to be understood in descriptivist terms. Because they reject descriptivism, these theories must offer a non-standard account of the meanings of ethical and normative sentences as well as related semantic facts, such as why certain sentences are inconsistent with each other. This paper fills out such a solution to (...) the negation problems, following some of the original emotivist ideas about the interplay of interests in conversation. We communicate both to share information and coordinate our actions, and we use distinctively normative language like deontic ‘must’ and ‘may’ to negotiate what people are to do. The kinds of disagreement involved in such negotiation can illuminate the issues with negation and inconsistency. This paper outlines a dynamic semantic system in which these ideas can bear fruit, developing the scorekeeping model of conversation. The result is clarification about what Frege-Geach worries can mean for nondescriptive semantics. (shrink)

This piece was written circa 1982–83, drawing in part on material from my PhD thesis (The Problem of the Single Case, Cambridge, 1981). In the thesis I proposed what would now be called an expressivist account of judgements of the form ‘It is probable that p’. One chapter, on which this paper builds, tried to defend the view against the Frege-Geach argument. This piece earned a revise and resubmit from Philosophical Review, but was never resubmitted. Parts of it made (...) their way into my ‘Semantic Minimalism and the Frege Point’, in Tsohatzidis, S.L.(ed.), Foundations of Speech Act Theory: Philosophical and Linguistic Perspectives, Routledge, 1994, pp. 132–55 (reprinted in Naturalism without Mirrors, Oxford, 2011, ch. 3) – though that paper favours a different approach to the Frege-Geach argument, leaning more heavily on semantic minimalism. I’m putting this piece online to facilitate self-citation. (shrink)

We use quotation marks when we wish to refer to an expression. We can and do so refer even when this expression is composed of characters that do not occur in our alphabet. That's why Tarski, Quine, and Geach's theories of quotation don't work. The proposals of Davidson, Frege, and C. Washington, however, do not provide a plausible account of quotation either. (Section I). The problem is to construct a Tarskian theory of truth for an object language that contains (...) quotation marks, without appealing to quotation marks in the metalanguage. I propose to supply Tarski's truth definition with one axiom that determines the denotation of all expressions containing quotation marks. According to this axiom, quotation marks create a non-extensional context. Since admitting such contexts does not lead to any difficulties in the recursive truth characterization, we may indeed dispense with extensionalism. (Section II). Finally, I argue that we classify and denote expressions in the very same way that we classify and denote extralinguistic entities. Both tokens and types of written signs can be easily incorporated into the naturalist's worldview. (Section III). (shrink)

We develop a novel solution to the negation version of the Frege-Geach problem by taking up recent insights from the bilateral programme in logic. Bilateralists derive the meaning of negation from a primitive *B-type* inconsistency involving the attitudes of assent and dissent. Some may demand an explanation of this inconsistency in simpler terms, but we argue that bilateralism’s assumptions are no less explanatory than those of *A-type* semantics that only require a single primitive attitude, but must stipulate inconsistency elsewhere. (...) Based on these insights, we develop a version of B-type expressivism called *inferential expressivism*. This is a novel semantic framework that characterises meanings by inferential roles that define which *attitudes* one can *infer* from the use of terms. We apply this framework to normative vocabulary, thereby solving the Frege-Geach problem generally and comprehensively. Our account moreover includes a semantics for epistemic modals, thereby also explaining normative terms under epistemic modals. (shrink)

Michael Ridge claims to have ‘finessed’ the Frege-Geach Problem ‘on the cheap’. In this short paper I explain a couple of the reasons why this thought is premature.

Noncognitivism about normative judgment is the view that normative judgment is a distinctive kind of mental state, identical neither to belief or desire, but desire-like in its functional role and direction of fit. Noncognitivism about intention (also called the “distinctive practical attitude” theory) is the view that intention is a distinctive kind of mental state, identical neither to belief or desire, but desire-like in its functional role and direction of fit. While these theories are alike in several ways, they have (...) rarely been discussed in concert. This paper studies the relation between these two theories, focusing on the question of whether noncognitivism about intention faces an analogue of the well-known Frege-Geach problem for noncognitivism about normative judgment. I argue that whether it faces the Frege-Geach problem depends on how it treats the distinction between what Anscombe called expressions of intention and personal predictions. I show that there is substantial pressure to treat that distinction as semantic, and that a variant of the Frege-Geach problem arises for versions of noncognitivism about intention that go this route. Yet some philosophers of action may be willing to resist this pressure, and I develop a pragmatic account of the distinction that would allow such philosophers to avoid the Frege-Geach problem altogether. I argue that this pragmatic account has significant independent appeal. Notably, it provides a way for noncognitivists about intention to undercut the force of a recent argument for cognitivism due to Berislav Marušić and John Schwenkler. (shrink)

In this paper, we present one of the main starting points of naturalism in ethics: Geach’s challenge against non-cognitivism. We try to find an answer to Geach’s challenge in the notion of family resemblance applied to ethics. In doing so we recover a not much-discussed influence of Moore on Wittgenstein’s conception of family resemblance, which leads us to define Wittgenstein as non-non-cognitivist in ethics. -/- Pre print (some changes in the published edition).

At the heart of semantics in the 20th century is Frege’s distinction between sense and force. This is the idea that the content of a self-standing utterance of a sentence S can be divided into two components. One part, the sense, is the proposition that S’s linguistic meaning and context associates with it as its semantic interpretation. The second component is S’s illocutionary force. Illocutionary forces correspond to the three basic kinds of sentential speech acts: assertions, orders, and questions. Forces (...) are then kinds of acts in which propositions are deployed with certain purposes. I sketch a speech-act theoretic semantics in which that distinction does not hold. Instead of propositions and forces, the theory proposes proto-illocutionary acts and illocutionary acts. The orthodox notion of a proposition plays no role in the framework, which is a good thing, since that notion is deeply problematic. The framework also shows how expressionists, who embrace a sophisticated speech-act framework, face no Frege-Geach embedding problem, since the latter assumes the Sense/Force distinction. (shrink)

The paper reconstructs Moore's Open Question Argument (OQA) and discusses its rise and fall. There are three basic objections to the OQA: Geach's point, that Moore presupposes that ?good? is a predicative adjective (whereas it is in fact attributive); Lewy's point, that it leads straight to the Paradox of Analysis; and Durrant's point that even if 'good' is not synonymous with any naturalistic predicate, goodness might be synthetically identical with a naturalistic property. As against Geach, I argue that (...) 'good' has both predicative and attributive uses and that in moral contexts it is difficult to give a naturalistic account of the attributive 'good'. To deal with Lewy, I reformulate the OQA. But the bulk of the paper is devoted to Durrant's objection. I argue that the post-Moorean programme of looking for synthetic identities between moral and naturalistic properties is either redundant or impossible. For it can be carried through only if 'good' expresses an empirical concept, in which case it is redundant since naturalism is true. But 'good' does not express an empirical concept (a point proved by the reformulated OQA). Hence synthetic naturalism is impossible. I discuss direct reference as a possible way out for the synthetic naturalist and conclude that it will not work. The OQA may be a bit battered but it works after a fashion. (shrink)

This paper was part of a special online issue on Truth. I critically discuss Peter Geach's paper "Truth and God".

In English, in order to speak about Arthur’s attitudes, we use sentences like “Arthur believes that natural language is messy”. For sentences of this kind we have a standard theory, according to which the ‘that’-clause ‘that natural language is messy’ denotes a proposition. As Prior showed for the first time, the standard theory appears to be at odds with some linguistic data. Geach and Prior both assumed that linguistic data are to be taken as reliable guides to a correct (...) semantic account and I will start by raising some worries concerning their methodology. Because of these data, Prior and Geach suggested some non-standard accounts. I will then show that if we take linguistic data seriously, their non-standard accounts do not fare any better than the standard theory. My general conclusion will thus not only be that Prior’s and Geach’s methodology is disputable, but also that their conclusions do not seem to follow even if we grant the reliability of their methodology.

Expressive-Assertivism, a metaethical theory championed by Daniel Boisvert, is sometimes considered to be a particularly promising form of hybrid expressivism. One of the main virtues of Expressive-Assertivism is that it seems to offer a simple solution to the Frege-Geach problem. I argue, in contrast, that Expressive-Assertivism faces much the same challenges as pure expressivism.

Philosophers should consider a hybrid meta-ethical theory that includes elements of both moral expressivism and moral error theory. Proponents of such an expressivist-error theory hold that all moral utterances are either expressions of attitudes or expressions of false beliefs. Such a hybrid theory has two advantages over pure expressivism, because hybrid theorists can offer a more plausible account of the moral utterances that seem to be used to express beliefs, and hybrid theorists can provide a simpler solution to the Frege- (...) class='Hi'>Geach problem. The hybrid theory has three advantages over pure error theory, because hybrid theorists can offer a more plausible account of the moral utterances that seem to be used to express attitudes, hybrid theorists can more easily explain moral motivation, and hybrid theorists can avoid the implausible claim that all moral discourse is radically mistaken. Accordingly, such a hybrid theory should be more attractive than pure expressivism or pure error theory to philosophers who are skeptical about moral facts and truth. (shrink)

Contemporary accounts of the Trinity and Incarnation sometimes employ aspects of Peter Geach's theory of relative identity. Geach's theory provides an account not merely of identity predicates, but also proper names and restricted quantification. In a previous work I developed an account of the doctrines of the Trinity and Incarnation incorporating these three aspects of Geach's theory and tried to show how each might contribute to our understanding of the doctrines. Joseph Jedwab has recently argued that my (...) account—or any that employs Geach's treatment of restricted quantifiers—leads to serious doctrinal errors. I reply to his criticisms. (shrink)

P. T. Geach has argued that it is impossible to demonstrate that the doctrine of the Trinity is consistent. I try to show why -- on a common understanding of the notion of consistency -- his reasoning is flawed and why, on Geach’s own principles, one should expect that if the doctrine of the Trinity is true then it will be possible to prove that the doctrine is consistent, and it will be possible to do this in a (...) way that makes no appeal to the truth of any religious doctrine.

In the middle of the 20th century, it was a common Wittgenstein-inspired idea in philosophy that for a linguistic expression to have a meaning is for it to be governed by a rule of use. In other words, it was widely believed that meanings are to be identified with use-conditions. However, as things stand, this idea is widely taken to be vague and mysterious, inconsistent with “truth-conditional semantics”, and subject to the Frege-Geach problem. In this paper I reinvigorate the (...) ideas that meaningfulness is a matter of being governed by rules of use and that meanings are best thought of in terms of use-conditions. I will do this by sketching the Rule-Governance view of the nature of linguistic meaningfulness, showing that the view isn’t by itself subject to the two problems, and explain why the idea has had a lasting appeal to philosophers from Strawson to Kaplan and why we should find it continually attractive.

Expressivists have a problem with negation. The problem is that they have not, to date, been able to explain why ‘murdering is wrong’ and ‘murdering is not wrong’ are inconsistent sentences. In this paper, I explain the nature of the problem, and why the best efforts of Gibbard, Dreier, and Horgan and Timmons don’t solve it. Then I show how to diagnose where the problem comes from, and consequently how it is possible for expressivists to solve it. Expressivists should accept (...) this solution, I argue, because it is demonstrably the only way of avoiding the problem, and because it generalizes. Once we see how to solve the negation problem, I show, it becomes easy to state a constructive, compositional expressivist semantics for a purely normative language with the expressive power of propositional logic, in which we can for the first time give explanatory, formally adequate expressivist accounts of logical inconsistency, logical entailment, and logical validity. As a corollary, I give what I take to be the first real expressivist explanation of why Geach’s original moral modus ponens argument is genuinely logically valid. This proves that the problem with expressivism cannot be that it can’t account for the logical properties of complex normative sentences. But it does not show that the same solution can work for a language with both normative and descriptive predicates, let alone that expressivists are able to deal with more complex linguistic constructions like tense, modals, or even quantifiers. In the final section, I show what kind of constraints the solution offered here would place expressivists under, in answering these further questions. (shrink)

The plane was going to crash, but it didn't. Johnny was going to bleed to death, but he didn't. Geach sees here a changing future. In this paper, I develop Geach's primary argument for the (almost universally rejected) thesis that the future is mutable (an argument from the nature of prevention), respond to the most serious objections such a view faces, and consider how Geach's view bears on traditional debates concerning divine foreknowledge and human freedom. As I (...) hope to show, Geach's view constitutes a radically new view on the logic of future contingents, and deserves the status of a theoretical contender in these debates. (shrink)

In this paper, I provide a new reading of Wittgenstein’s N operator, and of its significance within his early logical philosophy. I thereby aim to resolve a longstanding scholarly controversy concerning the expressive completeness of N. Within the debate between Fogelin and Geach in particular, an apparent dilemma emerged to the effect that we must either concede Fogelin’s claim that N is expressively incomplete, or reject certain fundamental tenets within Wittgenstein’s logical philosophy. Despite their various points of disagreement, however, (...) Fogelin and Geach nevertheless share several common and problematic assumptions regarding Wittgenstein’s logical philosophy, and it is these mistaken assumptions which are the source of the dilemma. Once we recognize and correct these, and other, associated expository errors, it will become clear how to reconcile the expressive completeness of Wittgenstein’s N operator, with several commonly recognized features of, and fundamental theses within, the Tractarian logical system.

This essay argues for a 'relationist' treatment of intentional identity sentences like (1) "Hob believes that a witch blighted Bob's mare and Nob believes that she killed Cob's sow" (Geach 1967). According to relationism, facts of the form "a believes that p and b believes that q" are not in general reducible to facts of the form "c believes that r". We first argue that extant, non-relationist treatments of intentional identity are unsatisfactory, and then go on to motivate and (...) explore a relationist alternative in some detail. We show that the general thesis of relationism can be directly motivated via cases already discussed in the literature, and then develop a particular version of relationism couched in the possible worlds framework. The resulting theory avoids the problems facing its non-relationist rivals, and yields a natural account of the truth-conditions of (1), truth-conditions which can be generated in a compositional manner by a version of dynamic semantics. The theory also helps us to cleanly separate semantic questions about intentional identity from metasemantic ones. (shrink)

Many including Judith Jarvis Thomson, Philippa Foot, Peter Geach, Richard Kraut, and Paul Ziff have argued for good simpliciter skepticism. According to good simpliciter skepticism, we should hold that there is no concept of being good simpliciter or that there is no property of being good simpliciter. I first show that prima facie we should not accept either form of good simpliciter skepticism. I then show that all of the arguments that good simpliciter skeptics have proposed for their view (...) fail to show that we have good reason to accept good simpliciter skepticism. So, I show that we do not have good reason to accept good simpliciter skepticism. (shrink)

Mark Schroeder has argued that all reasonable forms of inconsistency of attitude consist of having the same attitude type towards a pair of inconsistent contents (A-type inconsistency). We suggest that he is mistaken in this, offering a number of intuitive examples of pairs of distinct attitudes types with consistent contents which are intuitively inconsistent (B-type inconsistency). We further argue that, despite the virtues of Schroeder's elegant A-type expressivist semantics, B-type inconsistency is in many ways the more natural choice in developing (...) an expressivist account of moral discourse. We close by showing how to adapt ordinary formality-based accounts of logicality to define a B-type account of logical inconsistency and distinguish it from both semantic and pragmatic inconsistency. In sum, we provide a roadmap of how to develop a successful B-type expressivism. (shrink)

In recent work, Amie Thomasson has defended what she calls normativism about metaphysical modality. She claims that discourse about metaphysical modality primarily serves a non-descriptive function, and builds a theory of such discourse around this claim. In this text, I critically discuss Thomasson’s view. Chief among the problems I go on to discuss is that Thomasson’s account of the meanings of modal expressions does not solve the problems she intends it to solve (among them solving the Frege-Geach problem), that (...) there is no significant ordinary practice of making metaphysically modal claims in the first place, and that the general problem she identifies and seeks to solve goes beyond discourse about metaphysical modality so a theory focused on metaphysical modal discourse is not general enough to deal with the problem.

This chapter identifies a novel family of metaethical theories that are non-descriptive and that aim to explain the action-guiding qualities of normative thought and language. The general strategy is to consider different relations language might bear to a given content, where we locate descriptivity (or lack of it) in these relations, rather than locating it in a theory that begins with the expression of states of mind, or locating it in a special kind of content that is not way-things-might-be content. (...) One such view is sketched, which posits two different content-fixing cognitive roles for bits of language. One role fixes a descriptive relation to content and another role fixes a non-descriptive relation to content. In addition to non-descriptivity and action guidance, the chapter briefly considers the appearance of mind-independent authoritative force, disagreement, and Frege–Geach concerns. (shrink)

The basic idea of expressivism is that for some sentences ‘P’, believing that P is not just a matter of having an ordinary descriptive belief. This is a way of capturing the idea that the meaning of some sentences either exceeds their factual/descriptive content or doesn’t consist in any particular factual/descriptive content at all, even in context. The paradigmatic application for expressivism is within metaethics, and holds that believing that stealing is wrong involves having some kind of desire-like attitude, with (...) world-tomind direction of fit, either in place of, or in addition to, being in a representational state of mind with mind-to-world direction of fit. Because expressivists refer to the state of believing that P as the state of mind ‘expressed’ by ‘P’, this view can also be described as the view that ‘stealing is wrong’ expresses a state of mind that involves a desire-like attitude instead of, or in addition to, a representational state of mind. According to some expressivists - unrestrained expressivists, as I’ll call them - there need be no special relationship among the different kinds of state of mind that can be expressed by sentences. Pick your favorite state of mind, the unrestrained expressivist allows, and there could, at least in principle, be a sentence that expressed it. Expressivists who seem to have been unrestrained plausibly include Ayer in Language, Truth, and Logic, and Simon Blackburn in many of his writings, including his [1984], [1993], and.. (shrink)
