Psycholinguistic methods hold great promise for experimental philosophy. Many philosophical thought experiments and arguments proceed from verbal descriptions of possible cases. Many relevant intuitions and conclusions are driven by spontaneous inferences about what else must also be true in the cases described. Such inferences are continually made in language comprehension and production. This chapter explains how methods from psycholinguistics can be employed to study such routine automatic inferences, with a view to assessing intuitions and reconstructing arguments. We demonstrate how plausibility ratings, pupillometry, and reading time measurements can be used to examine hypotheses about automatic inferences in speech and text comprehension. Two experiments on inferences from polysemous (perception-)verbs provide evidence of a potentially consequential ‘salience bias’. Findings help assess intuitions about unusual cases and analyse a philosophical paradox (‘argument from hallucination’). The paper thus illustrates how we can adapt psycholinguistic methods for philosophical purposes and demonstrates the methods’ philosophical usefulness.

Until recently, experimental philosophy has been associated with the questionnaire-based study of intuitions; however, experimental philosophers now adapt a wide range of empirical methods for new philosophical purposes. New methods include paradigms for behavioural experiments from across the social sciences as well as computational methods from the digital humanities that can process large bodies of text and evidence. This book offers an accessible overview of these exciting innovations. The volume brings together established and emerging research leaders from several areas of experimental philosophy to explore how new empirical methods can contribute to philosophical debates. Each chapter presents one or several methods new to experimental philosophy, demonstrating their application in a key area of philosophy and discussing their strengths and limitations. Methods covered include eye tracking, virtual reality technology, neuroimaging, statistical learning, and experimental economics as well as corpus linguistics, visualisation techniques and data and text mining. The volume explores their use in moral philosophy and moral psychology, epistemology, philosophy of science, metaphysics, philosophy of language, philosophy of mind and the history of ideas. Methodological Advances in Experimental Philosophy is essential reading for undergraduates, graduate students and researchers working in experimental philosophy.

The paper seeks to refute the idea that physiology can explain at best an organism’s behaviour, outward and inner, but not the conscious experiences that accompany that behaviour. To do so, the paper clarifies the idea by confrontation with an actual example of psychophysical explanation of perceptual experience. This reveals that the idea relies on a prejudice about physiological practice. Then the paper explores some peculiar ways in which this prejudice may survive its refutation. This is to bring out that such explanations of experience as are actually offered by contemporary psychophysics explain nothing less than what they purport to explain; and that these achievements are not, in some peculiar way, more remarkable than equally clever physical explanations of other phenomena

An important strand of current experimental philosophy promotes a new kind of methodological naturalism. This chapter argues that this new ‘metaphilosophical naturalism’ is fundamentally consistent with key tenets of Wittgenstein’s metaphilosophy, and can provide empirical foundations for therapeutic conceptions of philosophy. Metaphilosophical naturalism invites us to contribute to the resolution of philosophical problems about X by turning to scientific findings about the way we think about X – in general or when doing philosophy. This new naturalism encourages us to use resources from psychology that can empirically vindicate precisely some of the most controversial aspects of Wittgenstein’s conception of philosophy: They can establish the need, and provide key tools, for something worth calling ‘therapy’, in philosophy. As ‘pudding proof’ this chapter shows how methods and findings from psycholinguistics motivate and facilitate a therapeutic approach to a characteristically philosophical problem: ‘the problem of perception’.

Analogical reasoning is often employed in problem-solving and metaphor interpretation. This paper submits that, as a default, analogical reasoning addressing these different tasks employs different mapping strategies: In problem-solving, it employs analogy-maximising strategies (like structure mapping, Gentner & Markman 1997); in metaphor interpretation, analogy-minimising strategies (like ATT-Meta, Barnden 2015). The two strategies interact in analogical reasoning with conceptual metaphors. This interaction leads to predictable fallacies. The paper supports these hypotheses through case-studies on ‘mind’-metaphors from ordinary discourse, and abstract problem-solving in the philosophy of mind, respectively: It shows that (1) default metaphorical interpretations for vision- and space-cognition metaphors can be derived with a variant of the analogy-minimising ATT-Meta approach, (2) philosophically influential introspective conceptions of the mind can be derived with conceptual metaphors only through an analogy-maximising strategy, and (3) the interaction of these strategies leads to hitherto unrecognised fallacies in analogical reasoning with metaphors. This yields a debunking explanation of introspective conceptions.

The paper builds on a methodological idea from experimental philosophy and on findings from psycholinguistics, to develop and defend ordinary language analysis (OLA) as practiced in J.L. Austin’s Sense and Sensibilia. That attack on sense-datum theories of perception focuses on the argument from illusion. Through a case-study on this paradoxical argument, the present paper argues for a form of OLA which is psychologically informed, seeks to expose epistemic, rather than semantic, defects in paradoxical arguments, and is immune to the main objections to ordinary language philosophising, including those arising from the semantic/pragmatics distinction: A key project in current experimental philosophy is to develop psychological explanations of philosophically relevant intuitions that help us determine what warrant thinkers have for accepting them. Psycholinguistic work on the role of stereotypes in verb-comprehension has shown that intuitive judgments can be generated by automatic cognitive processes that duplicate both semantic and pragmatic inferences and are shaped by dominant uses of words. For systematic reasons, philosophers are prone to unwittingly deviate from such dominant uses. Where this happens, they are liable to automatically infer unwarranted conclusions that strike them as intuitively compelling. OLA helps us to determine those dominant uses, to identify unwitting deviations from them, and thus to expose unwarranted intuitions – e.g., in the premises of paradoxical arguments. Ordinary language does not determine the bounds of sense but shapes our leaps of thought. The paper shows how this enables its ‘Austinian’ analysis to contribute to a novel, epistemic, resolution of philosophical paradoxes and problems.

How is it that speakers can get to know the meaning of any of indefinitely many sentences they have never encountered before? - the 'problem of linguistic creativity' posed by this question is a core problem of both philosophy of language and theoretical linguistics, and has sparked off a considerable amount of work in the philosophy of mind. The book establishes the failure of the familiar - compositional - approach to this problem, and then takes a radically new start: It develops core elements of the later Wittgenstein's conception of philosophy, and puts them to work to 'dissolve' the problem to prove it ill-framed by clarifying the questions posing it and breaking the spell of mistaken analogies informing it. This sharply focused monograph thus copes with a crucial problem that turns out to be a lot tougher than generally thought, and presents a precise and rigorous demonstration of an unfamiliar and exciting philosophical approach

The paper presents a novel account of nature and genesis of some philosophical problems, which vindicates a new approach to an arguably central and extensive class of such problems: The paper develops the Wittgensteinian notion of ‘philosophical pictures’ with the help of some notions adapted from metaphor research in cognitive linguistics and from work on unintentional analogical reasoning in cognitive psychology. The paper shows that adherence to such pictures systematically leads to the formulation of unwarranted claims, ill-motivated problems, and pointless theories. To do so, the paper proceeds from a case-study on a lastingly influential development in early modern philosophy: the adoption of the doctrine of secondary qualities, and its principal consequences. The findings motivate a new approach to an arguably extensive and important class of philosophical problems: to the problems we raise in the grip of philosophical pictures.

It is no surprise that empirical psychology refutes, again and again, assumptions of uneducated common sense. But some puzzlement tends to arise when scientific results appear to call into question the very conceptual framework of the mental to which we have become accustomed. This paper shall examine a case in point: Experiments on colour-discrimination have recently been taken to refute an assumption of first-person authority that appears to be constitutive of our ordinary notion of perceptual experience. The paper is to show that those experiments do not refute this assumption, and will suggest that the impression to the contrary is, ultimately, due to two factors: to misleading imagery and, above all, to mistaken translation from the technical idiom of empirical psychology into the plain English we use every day. This is to take the mystery out of what we shall see to constitute a pretty puzzle; it is to remind us just how careful we need to be when drawing conclusions from results of scientific psychology; and it is to bring out the virtues of methods commonly lumped together under the entirely misleading label of 'ordinary language philosophy', of methods far more useful than their common caricature would make one think.

The paper outlines the evolution of on-going meta-philosophical debates about intuitions, explains different notions of 'intuition' employed in these debates, and argues for the philosophical relevance of intuitions in an aetiological sense taken from cognitive psychology. On this basis, it advocates a new kind of methodological naturalism which it finds implicit, for instance, in the warrant project in experimental philosophy: a meta-philosophical naturalism that promotes the use of scientific methods in meta-philosophical investigations. This 'higher-order' naturalism is consistent with both methodological naturalism and methodological rationalism about first-order philosophy, and can help us adjudicate between the two, in a piecemeal manner.

Experimental philosophy’s much-discussed ‘restrictionist’ program seeks to delineate the extent to which philosophers may legitimately rely on intuitions about possible cases. The present paper shows that this program can be (i) put to the service of diagnostic problem-resolution (in the wake of J.L. Austin) and (ii) pursued by constructing and experimentally testing psycholinguistic explanations of intuitions which expose their lack of evidentiary value: The paper develops a psycholinguistic explanation of paradoxical intuitions that are prompted by verbal case-descriptions, and presents two experiments that support the explanation. This debunking explanation helps resolve philosophical paradoxes about perception (known as ‘arguments from hallucination’).

Conceptual metaphors facilitate both productive and pernicious analogical reasoning. This article addresses the question: When and why does the frequently helpful use of metaphor become pernicious? By applying the most influential theoretical framework from cognitive psychology in analysing the philosophically most prominent example of pernicious metaphorical reasoning, we identify a philosophically relevant but previously undescribed fallacy in analogical reasoning with metaphors. We then outline an explanation of why even competent thinkers commit this fallacy and obtain a psychologically informed ‘debunking’ explanation of the kind experimental philosophy’s ‘sources project’ seeks

One major facilitator of analogical reasoning is conceptual metaphor: cross-domain mappings that preserve relations and thereby motivate the extension of linguistic terms from the source to the target domain. Their conscious and explicit use in analogical reasoning has been helpful and productive in disciplines ranging from physics to psychology, and philosophy. At the same time, students of metaphor have suggested that partially unwitting use of conceptual metaphors led to unsound but intuitive conceptions of the mind, in philosophy and psychology. This paper develops an explanation of some highly influential intuitions from the philosophy of mind, which helps answer the resulting question: When and why does the frequently helpful use of metaphors in analogical reasoning turn pernicious? In response, the paper brings together two hitherto largely distinct strands of research from cognitive psychology, in a case-study on the philosophy of mind: The paper uses structure-mapping theory to explain how simple analogical reasoning generates conceptual metaphors that facilitate more complex analogical reasoning, which is often non-intentional. Second, the paper examines how such reasoning interacts with partial-matching effects in memory-based processing. Drawing on Budiu and Anderson’s model of “information-based processing”, the paper shows that this interaction leads to predictable fallacies. It brings out the relevance of such fallacies by showing that they shaped introspective conceptions of the mind that dominated philosophical discourse throughout early modernity and retain some cultural influence to this day. On this basis, the paper delineates when and where those fallacies are liable to occur

The later Wittgenstein advanced a revolutionary but puzzling conception of how philosophy ought to be practised: Philosophical problems are not to be coped with by establishing substantive claims or devising explanations or theories. Instead, philosophical questions ought to be treated ‘like an illness’. Even though this ‘non-cognitivism’ about philosophy has become a focus of debate, the specifically ‘therapeutic’ aims and ‘non-theoretical’ methods constitutive of it remain ill understood. They are motivated by Wittgenstein’s view that the problems he addresses result from misinterpretation, driven by ‘urges to misunderstand’. The present paper clarifies this neglected concept and analyses how such ‘urges’ give rise to pseudo-problems of one particular, hitherto little understood, kind. This will reveal ‘therapeutic’ aims reasonable and ‘non-theoretical’ methods necessary, in one clearly delineated and important part of philosophy. I.e.: By developing a novel account of nature and genesis of one important class of philosophical problems, the paper explains and vindicates a revolutionary reorientation of philosophical work, at the level of both aims and methods.

The paper develops and addresses a major challenge for therapeutic conceptions of philosophy of the sort increasingly attributed to Wittgenstein. To be substantive and relevant, such conceptions have to identify “diseases of the understanding” from which philosophers suffer, and to explain why these “diseases” need to be cured in order to resolve or overcome important philosophical problems. The paper addresses this challenge in three steps: With the help of findings and concepts from cognitive linguistics and cognitive psychology, it redevelops the Wittgensteinian notion of “philosophical pictures.” Through a case study on seminal versions of familiar mind-body problems, it examines how such pictures shape philosophical reflection and generate ill-motivated but captivating problems. Third, it shows that philosophical pictures are constitutive of “diseases of the understanding,” in a quite strict sense of the term. On this basis, the paper explains when and why philosophical therapy is required

This paper pioneers the use of methods and findings from psycholinguistics in experimental philosophy’s ‘sources project’. On this basis, it clarifies the epistemological relevance of empirical findings about intuitions – a key methodological challenge to experimental philosophy. The sources project (aka ‘cognitive epistemology of intuitions’) seeks to develop psychological explanations of philosophically relevant intuitions, which help us assess their evidentiary value. One approach seeks explanations which trace relevant intuitions back to automatic cognitive processes that are generally reliable but predictably generate cognitive illusions under specific vitiating circumstances. The paper develops and experimentally tests such an explanation for intuitions at the root of a historically influential paradox about perception (‘argument from illusion’). The explanation traces these intuitions to stereotype-driven amplification, an automatic process routinely involved in language comprehension (e.g., understanding philosophical case-descriptions). Distributional semantics analysis and a forced-choice plausibility ranking task are employed to establish the relevant verb-associated stereotypes. The paper argues that the inferences facilitated by these stereotypes are generally reliable, but shows that vitiating circumstances obtain in the formulation of the targeted paradox. On this basis, the paper explores two complementary strategies for assessing the evidentiary value of intuitive judgments.

A certain orthodoxy has it that understanding is essentially computational: that information about what a sentence means is something that may be generated by means of a derivational process from information about the significance of the sentences constituent parts and of the ways in which they are put together. And that it is therefore fruitful to study formal theories acceptable as compositional theories of meaning for natural languages: theories that deliver for each sentence of their object-language a theorem acceptable as statement of its meaning and derivable from axioms characterizing subsentential expressions and operations forming that sentence. This paper is to show that there is something deeply wrong with these ideas, namely that they are based on a certain confusion about ascriptions of semantic knowledge. The paper is to make this point by considering a semantic theorist who has explicit knowledge of a theory of truth for L. And by showing that all the theorist needs to have knowledge of to understand the sentences of L are these axioms -- that the derivation of T-theorems is epistemically redundant. And that this doesnt change when we turn from explicit to what has been called tacit knowledge.

The construction and analysis of arguments supposedly are a philosopher's main business, the demonstration of truth or refutation of falsehood his principal aim. In Sense and Sensibilia, J.L. Austin does something entirely different: He discusses the sense-datum doctrine of perception, with the aim not of refuting it but of 'dissolving' the 'philosophical worry' it induces in its champions. To this end, he 'exposes' their 'concealed motives', without addressing their stated reasons. The paper explains where and why this at first sight outrageous aim and approach are perfectly sensible, how exactly Austin proceeds, and how his approach can be taken further. This shows Austin to be a pioneer of the currently much discussed notion of philosophy as therapy, reveals a subtle and unfamiliar use of linguistic analysis that is not open to the standard objections to ordinary language philosophy, and yields a novel and forceful treatment of the sense-datum doctrine.

: Psychological explanations of philosophical intuitions can help us assess their evidentiary value, and our warrant for accepting them. To explain and assess conceptual or classificatory intuitions about specific situations, some philosophers have suggested explanations which invoke heuristic rules proposed by cognitive psychologists. The present paper extends this approach of intuition assessment by heuristics-based explanation, in two ways: It motivates the proposal of a new heuristic, and shows that this metaphor heuristic helps explain important but neglected intuitions: general factual intuitions which have been highly influential in the philosophies of mind and perception but neglected in on-going debates in the epistemology of philosophy. To do so, the paper integrates results from three philosophically pertinent but hitherto largely unconnected strands of psychological research: research on intuitive judgement, analogy and metaphor, and memory-based processing, respectively. The paper shows that the heuristics-based explanation thus obtained satisfies the key requirements cognitive psychologists impose on such explanations, that it can explain the philosophical intuitions targeted, and that this explanation supports normative assessment of the intuitions' evidentiary value: It reveals whether particular intuitions are due to proper exercise of cognitive competencies or constitute cognitive illusions

Abstract: The notion that philosophy can be practised as a kind of therapy has become a focus of debate. This article explores how philosophy can be practised literally as a kind of therapy, in two very different ways: as philosophical therapy that addresses “real-life problems” (e.g., Sextus Empiricus) and as therapeutic philosophy that meets a need for therapy which arises in and from philosophical reflection (e.g., Wittgenstein). With the help of concepts adapted from cognitive and clinical psychology, and from cognitive linguistics, the article shows that both philosophical projects address important and literally therapeutic tasks and explains how they can do so with genuinely philosophical argument and analysis. This brings into view new applications for philosophy, a need for therapy in core areas of the subject, and the outline of a new approach to meet what will be shown to be a central need

The paper clarifies therapeutic ideas about philosophical method which Wittgenstein puts forward in his "Big Typescript". It does so by analysing how Wittgenstein treats the question 'What is meaning?', in that part of the same work from which the opening sections of his "Philosophical Investigations" derive. On this basis, the paper explains why Wittgenstein set himself a therapeutic goal, why this is reasonable, and how he sought to attain that goal without 'pronouncing new truths about the subject of the investigation', viz. meaning.

Intuitive judgments elicited by verbal case-descriptions play key roles in philosophical problem-setting and argument. Experimental philosophy's ‘sources project’ seeks to develop psychological explanations of philosophically relevant intuitions which help us assess our warrant for accepting them. This article develops a psycholinguistic explanation of intuitions prompted by philosophical case-descriptions. For proof of concept, we target intuitions underlying a classic paradox about perception, trace them to stereotype-driven inferences automatically executed in verb comprehension, and employ a forced-choice plausibility-ranking task to elicit the relevant stereotypical associations of perception- and appearance-verbs. We obtain a debunking explanation that resolves the philosophical paradox.

The paper develops a novel account of the nature and genesis of some philosophical problems, which motivates an unfamiliar form of philosophical criticism that was pioneered by the later Wittgenstein. To develop the account, the paper analyses two thematically linked sets of problems, namely problems about linguistic understanding: a set of problems Wittgenstein discusses in a core part of his Philosophical Investigations, and the ‘problem of linguistic creativity’ that is central to current philosophy of language. The paper argues that these problems are generated by tacit and unwarranted presuppositions at odds with warranted beliefs the philosophers raising the problems reflectively hold at the same time. For a rigorous conceptualisation of this phenomenon, the paper develops the notion of a ‘philosophical picture’ first proposed by Wittgenstein, and specifies the particular class of philosophical problems that may be raised due to adherence to such pictures. The results motivate a new form of philosophical criticism: the systematic exposure of relevant philosophical pictures, and efforts to overcome their tacit influence on philosophical reflection.

The paper considers a version of the problem of linguistic creativity obtained by interpreting attributions of ordinary semantic knowledge as attributions of practical competencies with expressions. The paper explains how to cope with this version of the problem without invoking either compositional theories of meaning or the notion of `tacit knowledge' (of such theories) that has led to unnecessary puzzlement. The central idea is to show that the core assumption used to raise the problem is false. To render precise argument possible, the paper first identifies and removes some relevant semantic indeterminacy in philosophical talk of `semantic knowledge' and `information'. This yields rules for attributing the two to human speakers and information-processors, respectively. The paper then shows, first, that ordinary speakers qualify as possessing all along an other than finite and definite stock of semantic knowledge and, second, that a very simple information-processor running a procedural semantics qualifies as possessing an analogous stock of semantic information. The second result is used to bring out that the first is neither unduly impressive nor particularly puzzling.

Der Aufsatz stellt einen Strang der experimentellen Philosophie vor, der sich nicht mit empirischen Umfragen begnügt, sondern bemüht, psychologische Experimente und Erklärungen für die philosophische Arbeit nutzbar zu machen: Das prominent propagierte, aber bislang nur vereinzelt praktizierte Forschungsprogramm der kognitiven Epistemologie (alias ‚sources project‘) verwendet bereits vorliegende experimentelle und theoretische Ergebnisse der Kognitions- und Sozialpsychologie, um ihrerseits experimentell überprüfbare Erklärungen philosophisch relevanter Intuitionen zu entwickeln, die deren epistemologische Bewertung erlauben. Während die Diskussion in und um die experimentelle Philosophie sich bislang auf die Untersuchung von Intuitionen konzentrierte, die als Evidenz für oder gegen philosophische Theorien verwendet werden, behandelt dieser Aufsatz Intuitionen, die philosophische Paradoxa erzeugen und charakterisch philosophische Probleme aufwerfen. Er präsentiert Ergebnisse der Diskursprozessforschung aus Kognitionspsychologie und Psycholinguistik, insbesondere die empirisch gut untermauerte graded salience Hypothese und experimentelle Arbeiten zur Rolle von Stereotypen bei Verwendung und Interpretation von Verben. Auf dieser Grundlage entwickelt er eine ihrerseits experimentell überprüfbare Erklärung von Intuitionen, die ein klassisches Leitproblem der Philosophie der Wahrnehmung aufwerfen. Dieses (neuerdings schlicht so genannte) ‚Problem der Wahrnehmung‘ wird von einer Reihe von Paradoxa aufgeworfen, deren historisch einflussreichstes das sog. ‚Illusionsargument‘ ist. Der Aufsatz entwickelt eine Erklärung von Intuitionen, die diesem Argument als Prämissen dienen. Sie erlaubt uns – ohne naturalistischen Fehlschluss – zu zeigen, dass wir keine Berechtigung haben, diese Intuitionen zu akzeptieren. Der Aufsatz erläutert abschliessend, inwiefern dies zur Auflösung des Problems der Wahrnehmung beiträgt. Er führt exemplarisch vor, wie kognitive Epistemologie zu einer neuen Form philosophischer Problemauflösung beitragen kann.
