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.

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.

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.

This paper trials new experimental methods for the analysis of natural language reasoning and the development of critical ordinary language philosophy in the wake of J.L. Austin. Philosophical arguments and thought experiments are strongly shaped by default pragmatic inferences, including stereotypical inferences. Austin suggested that contextually inappropriate stereotypical inferences are at the root of some philosophical paradoxes and problems, and that these can be resolved by exposing those verbal fallacies. This paper builds on recent efforts to empirically document inappropriate stereotypical inferences that may drive philosophical arguments. We demonstrate that previously employed questionnaire-based output measures do not suffice to exclude relevant confounds. We then report an experiment that combines reading time measurements with plausibility ratings. The study seeks to provide evidence of inappropriate stereotypical inferences from appearance verbs that have been suggested to lie at the root of the influential ‘argument from illusion’. Our findings support a diagnostic reconstruction of this argument. They provide the missing component for proof of concept for an experimental implementation of critical ordinary language philosophy that is in line with the ambitions of current ‘evidential’ experimental philosophy.

What is the experience of someone who is “colour‐blind” like? This paper presents the results of a study that uses qualitative research methods to better understand the lived experience of colour blindness. Participants were asked to describe their experiences of a variety of coloured stimuli, both with and without EnChroma glasses—glasses which, the manufacturers claim, enhance the experience of people with common forms of colour blindness. More generally, the paper provides a case study in the nascent field of experimental philosophy of experience.

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.

Many biological systems experience a periodic environment. Floquet theory is a mathematical tool to deal with such time periodic systems. It is not often applied in biology, because linkage between the mathematics and the biology is not available. To create this linkage, we derive the Floquet theory for natural systems. We construct a framework, where the rotation of the Earth is causing the periodicity. Within this framework the angular momentum operator is introduced to describe the Earth’s rotation. The Fourier operators and the Fourier states are defined to link the rotation to the biological system. Using these operators, the biological system can be transformed into a rotating frame in which the environment becomes static. In this rotating frame the Floquet solution can be derived. Two examples demonstrate how to apply this natural framework

This paper presents a neglected philosophical approach, redevelops it on fresh empirical foundations, and seeks to bring out that it is of not merely historical interest. Building on ideas Ludwig Wittgenstein mooted in the early 1930s, Friedrich Waismann developed a distinctive metaphilosophy: Through case studies on particular philosophical problems, he identified a characteristic structure and genesis displayed by several philosophical problems and presented a distinctive dialogical method for dissolving problems of this kind. This method turns on exposing the need to endow philosophical questions or claims with more determinate meaning and meeting this need by proposing linguistic rules and explanations which the problems’ proponents are free to accept or reject. The approach is embedded in the view that unconscious thought decisively shapes the formulation of philosophical problems. This paper first presents the approach on the basis of Waismann’s texts and then redevelops it through a case study on the ‘problem of perception’ and within a post-Freudian conception of unconscious thought: We will draw on psycholinguistic findings about automatic inferences in language comprehension and production, to examine how unconscious cognition shapes the problem formulation. Findings provide fresh, empirical foundations for the approach which has advantages over more familiar critical projects in ordinary language philosophy, to which it is kindred in spirit.

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.

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

In this article, I develop the so‐called ‘problem of linguistic creativity’ for two object‐languages, one finite, the other infinite. I then employ an approach first outlined by Ludwig Wittgenstein’s collaborator Friedrich Waismann, to ‘dissolve’ that problem, in a sense made precise by working through the example. This is to unsettle the computational picture of linguistic understanding as turning on the generation of semantic information about sentences on the basis of semantic information about their constituent parts, and to provide a reasonably clear conception of to what such ‘philosophical dissolution’ of a problem amounts.

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

Empirical insights into language processing have a philosophical relevance that extends well beyond philosophical questions about language. This chapter will discuss this wider relevance: We will consider how experimental philosophers can examine language processing in order to address questions in several different areas of philosophy. To do so, we will present the emerging research program of experimental argument analysis (EAA) that examines how automatic language processing shapes verbal reasoning – including philosophical arguments. The evidential strand of experimental philosophy uses mainly questionnaire-based methods to assess the evidentiary value of intuitive judgments that are adduced as evidence for philosophical theories and as premises for philosophical arguments. Extending this prominent strand of experimental philosophy, EAA underpins such assessments, extends the scope of the assessments, and expands the range of the empirical methods employed: EAA examines how automatic inferences that are continually made in language comprehension and production shape verbal reasoning, and draws on findings about comprehension biases that affect the contextualisation of such default inferences, in order to explain and expose fallacies. It deploys findings to assess premises and inferences from premises to conclusions, in philosophical arguments. To do so, it adapts methods from psycholinguistics and recruits methods from computational linguistics.

Common arguments for realism about phenomenal consciousness contend that this is a folk concept, with proponents expecting it to be lexicalised in ordinary language. In English, the word ‘experience’ is typically regarded as the best candidate. This predicts that ‘experience’ will be used to refer to mental states and episodes, not only in philosophical but also in ordinary discourse. We conduct a corpus study in order to assess this claim and to understand the actual use of the word in non-academic, academic, and philosophical discourse. In non-academic discourse, uses that refer to knowledge or sources of knowledge, and to public events, are found to dominate. Uses that refer to mental states or episodes dominate only in the philosophy of mind (and not even in philosophy at large).
