AGAINST CARTESIAN MISTRUST: CAVELL,HUSSERL AND THE OTHER MIND SCEPTIC

This paper asks whether we should still be haunted by scepticism about other minds. It draws on the writings of Cavell and Husserl to show that there is some truth in the Cartesian premise that has given rise to scepticism about other minds, namely, that our self‐awareness is of a fundamentally different type from our awareness of objects and other subjects. While this leads Cavell to argue that there is a truth to scepticism, it proves the opposite to Husserl, viz. that other minds scepticism is necessarily non‐sensical. The paper shows why Husserl's position is more convincing than Cavell's. 1     

How to be a Normativist about the Nature of Belief

According to the normativist, it is built into the nature of belief itself that beliefs are subject to a certain set of norms. I argue here that only a normativist account can explain certain non‐normative facts about what it takes to have the capacity for belief. But this way of defending normativism places an explanatory burden on any normativist account that an account on which a truth norm is explanatorily fundamental simply cannot discharge. I develop an alternative account that can achieve explanatory adequacy where this sort of truth privileging account falls short.     

Spinoza on Counterpossible Inferences

As part of his geometrical method, Spinoza uses inferences involving impossibilities: what would follow if some impossibility were true. This paper examines a puzzle surrounding his use of such ‘counterpossible’ inferences. The puzzle consists of Spinoza's apparent acceptance of the following three claims: that counterpossible inferences can produce knowledge; that inference‐making produces knowledge only on the basis of a transition between ideas; and that counterpossible inferences are unthinkable. I argue for a solution to this puzzle, which interprets Spinoza's geometrical method as a form of syntactical manipulation.     

Assertion and relative truth

An account of assertion along truth-relativistic lines is offered. The main lines of relativism about truth are laid out and the problematic features that assertion acquires in the presence of relative truth are identified. These features are the possibility of coherently formulating norms of assertion and the possibility of grounding a rational practice of assertion upon relative truth. A solution to these problems is provided by formulating norms for making and assessing assertions that employ a suitably relativized truth predicate and a perspectival notion of correctness. Two potential objections to this proposal are addressed.     

Pragmatism and Philosophy of Science: A Critical Survey

After delineating the distinguishing features of pragmatism, and noting the resources that pragmatists have available to respond effectively as pragmatists to the two major objections to pragmatism, I examine and critically evaluate the various proposals that pragmatists have offered as a solution to the problem of induction, followed by a discussion of the pragmatic positions on the status of theoretical entities. Thereafter I discuss the pragmatic posture toward the nature of explanation in science. I conclude that pragmatism has (a) a generally compelling solution to Hume’s problem of induction; (b) no specific position on the status of theoretical entities, although something like the non‐realism of the sort developed by van Fraassen seems a defensible candidate for most pragmatists in general, even though there are non‐trivial objections to van Fraassen’s position; and (c) central to the pragmatic conception of scientific explanation is the abandonment of our common conception of truth as a necessary condition for sentences to provide adequate explanations, and a drift in the direction of a contextualist account of explanation.     

Fish traps and rabbit snares: Zhuangzi on judgement,truth and knowledge

We argue that the common attribution to Zhuangzi of both perspectivalism or relativism on the one hand, and scepticism on the other is fundamentally mistaken. While granting that it is reasonable to construe Zhuangzi as offering a perspectiva! position on judgement, we argue that Zhuangzi's perspectivalism does not commit him to a relativist position on truth or to scepticism about human knowledge. Rather, we maintain that Zhuangzi's attacks on the concepts of truth and knowledge are better seen as his articulation of a species of epistemological nihilism which rejects, as ultimately meaningless, the concepts of truth, reality, and knowledge.     

Truth or Meaning? A Question of Priority

There is an incompatibility between the deflationist approach to truth, which makes truth transparent on the basis of an antecedent grasp of meaning, and the traditional endeavour, exemplified by Davidson, to explicate meaning through of truth. I suggest that both parties are in the explanatory red: deflationist lack a non‐truth‐involving theory of meaning and Davidsonians lack a non‐deflationary account of truth. My focus is on the attempts of the latter party to resolve their problem. I look in detail at Davidson's more recent work and suggest that it seeks to articulate a primitive notion of truth that may balance between a notion that collapses into deflationism and one that is wholly subsumed under a general theory of interpretation. I conclude that this tightrope walk is ultimately unsuccessful. Equally, however, some reasons are provided for thinking that deflationism might be equally unsuccessful with its problem. ‘Truth or meaning?’remains an open question.     

Can Truthmaker Theorists Claim Ontological Free Lunches?

Truthmaker theorists hold that propositions about higher‐level entities (e.g. the proposition that there is a heap of sand) are often made true by lower‐level entities (e.g. by facts about the configuration of fundamental particles). This generates a problem: what should we say about these higher‐level entities? On the one hand, they must exist (since there are true propositions about them), on the other hand, it seems that they are completely superfluous and should be banished for reasons of ontological parsimony. Some truthmaker theorists—most prominently David Armstrong—have tried to solve this puzzle by arguing that these entities are ‘an ontological free lunch’, i.e. real existents that are still ‘no addition of being’. This answer is prima facie attractive, but I argue in this paper that the standard approaches to truthmaking—modal theories and grounding theories—are unable to vindicate the doctrine of the ontological free lunch, and thus fail to solve the problem of higher‐level entities. Fortunately, there is a non‐standard account of truthmaking available, the reductive explanation account, which succeeds where the standard approaches fail.     

The Perceiver's Share: Realism, Scepticism, and Response Dependence

Abstract: Response‐dispositional (RD) properties are standardly defined as those that involve an object's appearing thus or thus to some perceptually well‐equipped observer under specified epistemic conditions. The paradigm instance is that of colour or other such Lockean “secondary qualities”, as distinct from those—like shape and size—that pertain to the object itself, quite apart from anyone's perception. This idea has lately been thought to offer a promising alternative to the deadlocked dispute between hard‐line ‘metaphysical’ realists and subjectivists, projectivists, social constructivists, or hard‐line anti‐realists. A chief source text is Plato's Euthyphro, where the issue is posed in ethical terms: do the gods infallibly approve virtuous acts on account of their divine moral omniscience or are virtuous acts just those the gods approve? Among the areas proposed as amenable to an RD approach are epistemology, ethics, political theory, and philosophy of mathematics. It is claimed that by making due allowance for the involvement of normalised or optimised human responses one can steer a course between the twin poles of an objectivist realism that places truth beyond our cognitive grasp and an epistemic conception that confines truth within the limits of humanly attainable proof, knowledge, or verification. Here I argue—on the contrary—that RD approaches can be shown to offer nothing more than a variant of the same old realist versus anti‐realist dilemma. That is, they work out either as a trivial (tautologous) claim that ‘truth’ simply equates with ‘best judgement’ in the ideal (quasi‐objective) limit or as the claim—advanced by anti‐realists like Michael Dummett—that we cannot form any adequate conception of objective (recognition‐transcendent) truths. After looking at this issue in various contexts of debate, I conclude that one useful (if pyrrhic) outcome is to demonstrate the non‐availability of any middle‐ground stance. We are left with the strictly unavoidable choice between a realist or objectivist approach and one that assimilates truth to the consensus of accredited best opinion. This latter amounts to a roundabout, elaborately qualified version of the anti‐realist case.     

POLITICAL LIBERALISM WITHOUT SCEPTICISM

Political liberalism famously requires that fundamental political matters should not be decided by reference to any controversial moral, religious or philosophical doctrines over which reasonable people disagree. This means we, as citizens, must abstain from relying on what we believe to be the whole truth when debating or voting on fundamental political matters. Many critics of political liberalism contend that this requirement to abstain from relying on our views about the good life commits political liberalism to a kind of scepticism: we should abstain from relying on our views about the good life because we should be uncertain about the truth of those views. But this kind of scepticism is itself a controversial epistemic position which many reasonable people reject, thus apparently making political liberalism internally incoherent. This is the sceptical critique of political liberalism. This paper shows the sceptical critique to be false. The paper argues that the epistemic restraint required of citizens in political liberalism does not assume or imply any version of scepticism about our ability to know the good life. Liberal neutrality is motivated not by scepticism about our own views, but rather by a desire to justify fundamental political principles to others. ¹ 1 I would like to thank Rebecca Stone, Steve De Wijze, and an anonymous referee for many helpful comments on earlier versions of this paper.

A CLOSER LOOK AT CLOSURE SCEPTICISM

The paper argues that there is no valid closure principle that can be used to infer sceptical conclusions. My argument exploits the Gettier Intuition that knowledge is incompatible with accidentally true belief. This intuition is interpreted as placing a constraint on beliefs that can count as knowledge: only beliefs which are based on reasons that are relevantly linked to the beliefs' truth can qualify as knowledge. I argue that closure principles are to reflect this constraint by accommodating the requirement that a subject's belief p needs to be based on her competent derivation of p from a known q . The emerging account is finally argued to reconcile Dretske's anti-closure intuitions with the intuition that we can extend knowledge by deduction, while simultaneously blocking closure arguments for scepticism about the external world.     

Indirect Realism with a Human Face

Epistemic Indirect Realism (EIR) is the position that justification for contingent propositions about the extra‐mental world requires an inference based on a subjective, experiential mental state. One objection against EIR is that it runs contrary to common sense and practice; in essence, ordinary people do not form beliefs about things in the external world on the basis of experiential mental states. This objection implies EIR is contrary to ordinary experience, impractical, and leads to scepticism. In this paper, I will defend EIR against this objection by distinguishing EIR based on conceptual awareness and non‐conceptual awareness. In particular, I will argue that direct acquaintance provides sufficient (non‐conceptual) awareness that can explain how ordinary folks are capable of forming justified beliefs about the external world in a way consistent with EIR. Overall, I present a framework for showing that EIR can satisfy ordinary epistemic practices without betraying human nature or over‐intellectualizing the required epistemic standards for possessing a justified belief.     

The Logicality of Language: A new take on Triviality, “Ungrammaticality”, and Logical Form*

Recent work in formal semantics suggests that the language system includes not only a structure building device, as standardly assumed, but also a natural deductive system which can determine when expressions have trivial truth‐conditions (e.g., are logically true/false) and mark them as unacceptable. This hypothesis, called the ‘logicality of language’, accounts for many acceptability patterns, including systematic restrictions on the distribution of quantifiers. To deal with apparent counter‐examples consisting of acceptable tautologies and contradictions, the logicality of language is often paired with an additional assumption according to which logical forms are radically underspecified: i.e., the language system can see functional terms but is ‘blind’ to open class terms to the extent that different tokens of the same term are treated as if independent. This conception of logical form has profound implications: it suggests an extreme version of the modularity of language, and can only be paired with non‐classical—indeed quite exotic—kinds of deductive systems. The aim of this paper is to show that we can pair the logicality of language with a different and ultimately more traditional account of logical form. This framework accounts for the basic acceptability patterns which motivated the logicality of language, can explain why some tautologies and contradictions are acceptable, and makes better predictions in key cases. As a result, we can pursue versions of the logicality of language in frameworks compatible with the view that the language system is not radically modular vis‐á‐vis its open class terms and employs a deductive system that is basically classical.     

Theology,Metaphysics, and Realism about Truth

This essay examines the theological grounds for rejecting metaphysics and the correspondence theory of truth, and argues that while there are good grounds for rejecting a certain kind of metaphysically oriented theology, metaphysics per se is neither objectionable nor avoidable in Christian theology. In the process, it also defends a realist conception of truth against some recent theological criticisms, and argues that a commitment to a modest version of metaphysical realism and realism about truth is not only philosophically tenable, but also theologically preferable to non‐realist views.     

Absolute Time: The Limit of Kant's Idealism

I examine here if Kant can explain our knowledge of duration by showing that time has metric structure. To do so, I spell out two possible solutions: time's metric could be intrinsic or extrinsic. I argue that Kant's resources are too weak to secure any intrinsic, transcendentally‐based temporal metrics; but he can supply an extrinsic metric, based in a metaphysical fact about matter. I conclude that Transcendental Idealism is incomplete: it cannot account for the durative aspects of experience—or it can do so only with help from a non‐trivial metaphysics of material substance.     

MORAL PERCEPTION AND THE CAUSAL OBJECTION

One of the primary motivations behind moral anti‐realism is a deep‐rooted scepticism about moral knowledge. Moral realists attempt counter this worry by sketching a plausible moral epistemology. One of the most radical proposals in the recent literature is that we know moral facts by perception – we can literally see that an action is wrong, etc. A serious objection to moral perception is the causal objection. It is widely conceded that perception requires a causal connection between the perceived and the perceiver. But, the objection continues, we are not in appropriate causal contact with moral properties. Therefore, we cannot perceive moral properties. This papers demonstrates that the causal objection is unsound whether moral properties turn out to be secondary, natural properties; non‐secondary, natural properties; or non‐natural properties. 1     

One's Modus Ponens: Modality,Coherence and Logic

Recently, there has been a shift away from traditional truth‐conditional accounts of meaning towards non‐truth‐conditional ones, e.g., expressivism, relativism and certain forms of dynamic semantics. Fueling this trend is some puzzling behavior of modal discourse. One particularly surprising manifestation of such behavior is the alleged failure of some of the most entrenched classical rules of inference; viz., modus ponens and modus tollens. These revisionary, non‐truth‐conditional accounts tout these failures, and the alleged tension between the behavior of modal vocabulary and classical logic, as data in support of their departure from tradition, since the revisionary semantics invalidate some of these patterns. I, instead, offer a semantics for modality with the resources to accommodate the puzzling data while preserving classical logic, thus affirming the tradition that modals express ordinary truth‐conditional content. My account shows that the real lesson of the apparent counterexamples is not the one the critics draw, but rather one they missed: namely, that there are linguistic mechanisms, reflected in the logical form, that affect the interpretation of modal language in a context in a systematic and precise way, which have to be captured by any adequate semantic account of the interaction between discourse context and modal vocabulary. The semantic theory I develop specifies these mechanisms and captures precisely how they affect the interpretation of modals in a context, and do so in a way that both explains the appearance of the putative counterexamples and preserves classical logic.     

Discourse Structure and Cartesian Scepticism

Abstract

I provide a new account of the nature of Cartesian scepticism, in which I show that if we draw on the notion of discourse structure we can show exactly how Cartesian scepticism is induced and that it is, in principle, impossible to dispel. The account proceeds by showing that, given the nature of discourse structure, there is no absolute distinction between what we normally think of as factual discourse—as discourse about “the actual world” - and what we normally think of as fictional discourse - as discourse about “a fictional world” - and, in short, no absolute distinction between fact and fiction. The power of the account of Cartesian scepticism therefore resides in the power of the account of discourse structure, and accordingly the account of discourse structure should be of at least as much interest as the account of scepticism.     

Observers' Language Proficiencies and the Detection of Non‐native Speakers' Deception

We examined whether observers' language proficiencies affected their abilities to detect native and non‐native speakers' deception. Native and non‐native English speakers were videotaped as they either lied or told the truth about having cheated on a test. A total of 284 laypersons—who were either native or non‐native English speakers themselves—viewed these videos and indicated whether they believed that the speakers were being truthful or deceptive. Observers were more accurate when judging native speakers than when judging non‐native speakers, suggesting that perceptual fluency aided deception detection. Although there was no effect of observers' language proficiencies on discrimination, their belief that interviewees were telling the truth increased with proficiency. On the whole, these findings suggest that non‐native speakers may be at greater risk of being incorrectly classified in forensic contexts.Copyright © 2017 John Wiley & Sons, Ltd.
