This chapter presents a diagnostic account of the state of play in the epistemology of testimony, and proposes a virtue epistemological non-inferentialist alternative. This account depends on arguments substantiating a parallel between the moral cognitivist account of virtuous perception, and a proposed account of epistemically virtuous perception that the virtuous hearer possesses owing to a well-trained testimonial sensibility. He perceives his interlocutor as more, or less, credible in what she is telling him.Less

Frei's appeals to the "givenness" of revelation-the claim, for instance, that all doctrines or theological assertions are directly or indirectly grounded in faith, or that faith is rational in that it seeks understanding within a set of reasons afforded by God's revelatory activity in Scripture-incur charges of "revelational foundationalism." Chapter 6 employs recent treatments of epistemic foundationalism in order to dispel charges of "crypto-foundationalism" as well as answering the equally frequent charge that talk of "rationality intrinsic to faith" implicates Frei's thought in a type of fideism.Less

Discussions about the meaning of the word “ought” are pulled in two apparently competing directions. First, in ethical theory this word is used in the paradigmatic statement of ethical principles and conclusions about what some agent is obligated to do. This leads some ethical theorists to claim that the word “ought” describes a real relation, roughly, of being obligated to (realism) or expresses some non-cognitive attitude toward agents acting in certain ways (expressivism). Second, in theoretical linguistics this word is classified as a modal auxiliary verb alongside words like “might,” “may,” “can,” “must,” etc. This leads some theoretical linguists to claim that the word “ought” is a weak necessity modal, which can be modeled with universal quantification over a restricted set of possible worlds. This chapter seeks some resolution of this tension by showing how versions of realism and expressivism can be modified in light of the best semantics of “ought” as a weak necessity modal. In addition, the chapter explains how this semantics might point to a third view—inferentialism—that accounts for the meaning of “ought” not in terms of what relation it describes, nor in terms of what attitude it expresses, but rather in terms of its inferential role.Less

Recent philosophical debate about the meaning of knowledge claims has largely centred on the question of whether epistemic claims are plausibly thought to be context sensitive. The default assumption has been that sentences that attribute knowledge or justification (or whatever else is epistemic) have stable truth-conditions across different contexts of utterance, once any non-epistemic context sensitivity has been fixed. The contrary view is the contextualist view that such sentences do not have stable truth-conditions but can vary depending on the context of utterance. This debate manifestly presupposes that the meta-epistemological issue of accounting for the meaning of epistemic claims is to be settled by determining the truth-conditions of these claims. This chapter believes that this presupposition is undermotivated in light of two observations. First, many epistemologists see epistemic claims as evaluative or normative, in some sense. Second, in the meta-ethical debate most philosophers take alternatives to truth-conditional semantics, such as expressivism, as live options when it comes to evaluative or normative claims. As it turns out, the chapter proposes that expressivism doesn't provide a plausible account of normative concepts across the board. But considering it as an alternative in the meta-epistemological debate points the way to another alternative to truth-conditional semantics. This is a form of inferentialism. This chapter tries to motivate a move to epistemic inferentialism by showing how it overcomes worries about expressivism and interacts with plausible ideas about the social function epistemic claims play in our commerce with one another and the word.Less

It is argued that both proposals fail. Brandom overlooks that the ’non‐perspectival‐ness’ of objects is itself a relative and perspectival matter. Haugeland's suggestion fails because his notion of incompatibility is ambiguous and individualistic.Less

Reviews the debate between Elizabeth Fricker and Tony Coady over the role of inferences in testimony reception. It distinguishes between four areas of disagreement in the debate: phenomenology, psychology (the question regarding conscious and unconscious mechanisms), normative epistemology, and pragmatics (how do we talk about, and justify, the adoption of testimonial beliefs?). Argues against inferentialism, but it also identifies problems shared by Fricker and Coady: the assumption that testimony reception has a phenomenology, and the assumption that one can give context‐independent rules for the evaluation of testimony.Less

This book challenges a longstanding view that logic is absolutely general, and topic neutral, by developing several ways in which one can be a pluralist or relativist about logic. One of these is an extended argument that words and phrases like “valid” and “logical consequence” are polysemous or, perhaps better, are cluster concepts. The notions can be sharpened in various ways. This explains away some raging “debates” in the literature, such as that between inferentialists and advocates of a truth-conditional, model-theoretic approach, and between advocates of higher-order logic and those who limit logic to first-order. This book then shows how different logics are appropriate for different mathematical theories. This immediately raises central questions concerning meaning, both of words and phrases like “valid” and “implies” and of the logical terminology itself, words like “or” and “not,” as they are used in rigorous mathematical deduction. Do those words have the same meaning, in different theories with different logics, or does the meaning shift from theory to theory? This book proposes that this question of meaning shift is itself context-sensitive; it depends on what is salient in a conversation comparing the theories. The result is a kind of contextualism concerning logic. This book also deals with questions concerning the logic of both formal and philosophical foundational studies, especially when the various theories under study do not have the same logic.Less

The chapter applies the informational analysis of knowledge in order to pursue three goals. The first is to introduce the ‘knowledge game’, a new, simple and yet powerful tool for analysing some intriguing philosophical questions. The second is to apply the knowledge game as an informative test to discriminate between conscious (human) and conscious-less agents (zombies and robots), depending on which version of the game they can win. And the third is to use a version of the knowledge game to provide an answer to Dretske's question ‘how do you know you are not a zombie?’. At the end of the chapter one should have a better view of which agents count as conscious informational organisms (inforgs), that is, the sort of inforgs that can intentionally process relevant semantic information.Less

The book records a series of philosophical exchanges between its authors, amounting to a debate extended over more than fifteen years. Its subject matter is the nature and scope of reason. A central case at issue is basic logical knowledge, and the justification for basic deductive inferences, but the arguments range far more widely, at stake the distinctions between analytic and synthetic, and between a priori and a posteriori. The discussion naturally involves problems about the conditions for linguistic understanding and competence, and what it might be to grasp a concept or to have an intuition. Since reason is central to philosophical method, there are associated implications for how philosophy itself works, or should work. In particular, the discussion raises fundamental concerns about how to approach epistemology.Less

Rationalism about self-knowledge, of the kind elaborated and defended by writers such as Moran and Boyle, is an account of self-knowledge for an ideally rational homo philosophicus rather than for homo sapiens. Fast thinking, belief-perseverance, attitude-recalcitrance, and self-ignorance are all respects in which human beings are not homo philosophicus. Rationalism says that what my beliefs and other attitudes are can be determined by reflecting on what they ought rationally to be. This Transparency Method for acquiring self-knowledge is of limited value, and substitutes a harder question for a much easier one. This book defends a form of inferentialism about self-knowledge. Inferences from behavioural and psychological evidence are a basic source of self-knowledge for humans, including substantial self-knowledge and knowledge of our own beliefs, desires, and other attitudes. On this account, the supposed asymmetry between knowledge of oneself and knowledge of others is a difference in the kinds of evidence available in the two cases. Philosophical accounts of self-knowledge are criticized for neglecting substantial self-knowledge and focusing on relatively trivial self-knowledge. Knowledge of our own character, values, and emotions are all explained in inferentialist terms. Inner sense approaches to self-knowledge are rejected, and an account is given of the scope and sources of self-ignorance. The value of self-knowledge is explained in practical or pragmatic terms, by reference to its contribution to well-being, rather than by reference to ideals such as authenticity and unity.Less

The word ‘ought’ is one of the core normative terms, but it is also a modal word. This book develops a careful account of the semantics of ‘ought’ as a modal operator and uses this to motivate a novel inferentialist account of why ought-sentences have the meaning that they have. Traditionally, theories that treat normative statements as descriptions of how reality might be have claimed the advantage of continuity with truth-conditional approaches to semantics; and theories that treat normative statements as expressions of nonbelief attitudes have claimed the advantage of explaining their distinctive evaluative and motivational character. The inferentialist theory defended in this book agrees with descriptivist theories in metaethics that specifying the truth conditions of normative sentences is a central part of the explanation of their meaning. However, it is argued (based on the comparison to semantics for modal operators) that this doesn’t settle the question of whether ought-statements describe reality. Moreover, the inferentialist theory defended in this book also agrees with expressivist theories that normative statements have special evaluative potentials. However, it is argued that the standard Humean model of this kind of evaluation in terms of statements expressing desire-like pressures on action is too narrow. Accordingly, the traditional debate leaves unanswered important metasemantic questions about what it is in virtue of which ought-sentences have the meanings they have. The sort of inferentialism about ‘ought’ developed in this book is meant to provide a viable antidescriptivist but also antiexpressivist answer to these questions.Less

Quantum theory launched a revolution in twentieth-century physics. But we have yet to appreciate the revolution’s significance for philosophy. Most studies of the conceptual foundations of quantum theory first try to interpret the theory—to say how the world could possibly be the way the theory says it is. But, though fundamental, quantum theory is enormously successful without describing the world in its own terms. When properly applied, models of quantum theory offer good advice on the significance and credibility of claims about the world expressed in other terms. This first of several philosophical lessons of the quantum revolution dissolves the quantum measurement problem. Pragmatist treatments of probability and causation show how quantum theory may be used to explain the non-localized correlations that have been thought to involve ‘spooky’ instantaneous action at a distance. Given environmental decoherence, a pragmatist inferentialist approach to content shows when talk of quantum probabilities is licensed, resolves any residual worries about whether a quantum measurement has a determinate outcome, and solves a dilemma about the ontology of a quantum field theory. This approach to meaning and reference also reveals the nature and limits of objective description in the light of quantum theory. While these pragmatist approaches to probability, causation, explanation, and content may be independently motivated by philosophical argument, their successful application here illustrates their practical importance in helping philosophers come to terms with the quantum revolution.Less

In these brief comments, the author discusses the origins of his interest in the epistemology, why he has always found inferentialist accounts of it implausible, and why the similarities between the epistemology of logic and the epistemology of other domains have always been salient to him. There is also a brief account of the asymmetry between the role of internalism in Boghossian’s epistemology and the role of externalism in the author’s epistemology. Finally, there are some reflections on the ways in which we can hope to improve the shaky methodology of traditional epistemology, for example by making more use of formal methods and the findings of experimental psychology.Less
In these brief comments, the author discusses the origins of his interest in the epistemology, why he has always found inferentialist accounts of it implausible, and why the similarities between the epistemology of logic and the epistemology of other domains have always been salient to him. There is also a brief account of the asymmetry between the role of internalism in Boghossian’s epistemology and the role of externalism in the author’s epistemology. Finally, there are some reflections on the ways in which we can hope to improve the shaky methodology of traditional epistemology, for example by making more use of formal methods and the findings of experimental psychology.

This chapter replies to Boghossian’s defence of the a priori–a posteriori distinction against the arguments for its shallowness in?The Philosophy of Philosophy. In particular, it shows how to understand the example of an unorthodox thinker who is linguistically competent with conjunction but refuses to treat the rule of conjunction elimination as logically valid. It also rebuts Boghossian’s charge of circularity against the account of knowledge of metaphysical modality in terms of the cognitive capacities required to assess ordinary counterfactual conditionals. For the explanation of knowledge of logic and mathematics, the key significance is emphasized of the distinction between knowing the truth of what is in fact a necessary truth and knowing that it is necessary.Less

Inferentialism is explained as an attempt to provide an account of meaning that is more sensitive (than the tradition of truth-conditional theorizing deriving from Tarski and Davidson) to what is learned when one masters meanings. The logically reformist inferentialism of Dummett and Prawitz is contrasted with the more recent quietist inferentialism of Brandom. Various other issues are highlighted for inferentialism in general, by reference to which different kinds of inferentialism can be characterized. Inferentialism for the logical operators is explained, with special reference to the Principle of Harmony. The statement of that principle in the author’s book Natural Logic is fine-tuned here in the way obviously required in order to bar an interesting would-be counterexample furnished by Crispin Wright, and to stave off any more of the same.Less

The purpose of this chapter is to develop a number of different ways in which one can be a folk-relativist or pluralist about logic. One is an extended argument that phrases like “validity” and “logical consequence” are either polysemous or else they express cluster concepts. There are a number of distinct notions going by those names. This usefully explains away some of the ongoing debates in philosophical logic, such as that between inferentialists and advocates of a model-theoretic approach. A closely-related sort of pluralism arises from a perspective sometimes called “logic-as-model.” A third sort of pluralism emerges from an argument that logical consequence and validity are relative to a choice of logical terms. Another sort of pluralism concerns the possibility that the notion of logical consequence, or one of its articulations, is vague. On some accounts, vague expressions are relative to something, such as a sharpening or a conversational context.Less

Intuitions often are seen as inputs to theoretical reasoning: e.g. you might form a belief by taking an intuition at face value or take your intuitions as starting points in the method of reflective equilibrium. This chapter argues that in addition to these roles intuitions play a role in guiding action. The chapter reflects on the transmission of justification through inference: inferential internalists justify belief in the conclusion of an argument by inferring it from the premises in that argument. It endorses the idea that one’s ‘seeing’ such a support-relation relies on one’s having an intuition. Introducing Boghossian’s recent work against inferential internalism inspired by Carroll’s dialogue ‘What the Tortoise Said to Achilles,’ the chapter responds to Boghossian’s argument that intuitions work like mental imperatives and inferences are mental actions performed by obeying them. It then explores what it is in virtue of which intuitions play a guidance role, when they do so.Less

Ethical intuitionism is a species of foundationalism for which the outputs of intuition function as justificational regress-stoppers and also provide an independent basis for choosing between equally coherent moral theories. The leading contemporary ethical intuitionists characterize intuitions as resulting from non-inferential processes whose outputs provide justification sufficiently strong to rationally license belief in the contents of intuition. Various critics have used experimental arguments to suggest that the target judgements are unreliable and hence unable to provide such justification. The chapter argues that intuitionists should moderate their key claims, which may not provide justification strong enough to rationalize belief in the outputs of intuition absent confirming evidence. Even so, they can be fit to play both the regress-stopping and theory-testing roles. Furthermore, there is no need to define intuitions as non-inferential. A partly inferential process can provide materials for testing theories without introducing circularity into the overall method of justification.Less

This chapter develops and defends an unrestricted inferentialist theory of the meanings of logical constants. Unlike restricted inferentialism, unrestricted inferentialism puts no constraints on which rules can determine meanings. The foundations of inferentialism are also discussed, including various types of holism and the distinction between basic and derivative rules. In order to develop and defend a detailed inferentialist theory of logic, this chapter provides an inferentialist account of the “logical” constants, solves Carnap’s categoricity problem for the meanings of logical constants, and provides inferentialist approaches to both the psychology and metaphysics of logic. Finally, the chapter briefly discusses the challenge to unrestricted inferentialism posed by tonk and related types of bad company. Building on the foundation provided by Part I (chapters 1-2) of the book, this chapter provides a freestanding development and defense of logical inferentialism.Less
