From 1901 till, at least, 1919, Russell persistently maintained that there are two kinds of logic, between which he sharply discriminated: mathematical logic and philosophical logic. In this paper, we discuss the concept of philosophical logic, as used by Russell. This was only a tentative program that Russell did not clarify in detail, so our task will be to make it explicit. We shall show that there are three (-and-a-half) kinds of Russellian philosophical logic: (i) “pure logic”; (ii) philosophical logic (...) investigating the logical forms of propositions; (iii) philosophical logic exploring the logical forms of facts: in epistemology; and in the external world. In particular, Russell’s program or philosophical logic of the facts of the external world remained less than sketchily outlined. We shall discuss it in some detail in the hope that it can start a new life. (shrink)

A dominant strand of philosophical thought holds that natural kinds are clusters of objects with shared properties. Cluster theories of natural kinds are often taken to be a late twentieth-century development, prompted by dissatisfaction with essentialism in philosophy of biology. I will argue here, however, that a cluster theory of kinds had actually been formulated by William Whewell (1794-1866) more than a century earlier. Cluster theories of kinds can be characterized in terms of three central commitments, all of which are (...) present in Whewell’s work on classification. Like contemporary cluster theorists, Whewell claims that kinds are united by similarity, that many kinds do not have essences, and that there are “gaps” between kinds. Moreover, Whewell advises taxonomists to look for consilience (roughly, convergence) between different classificatory schemes, a recommendation that reinforces the identification of natural classes with property clusters. Thus Whewell was not only an early cluster theorist, but one with important insights into what a cluster theory of kinds means for the practice of classification. (shrink)

This chapter sheds light on a response to experimental philosophy that has not yet received enough attention: the reflection defense. According to proponents of this defense, judgments about philosophical cases are relevant only when they are the product of careful, nuanced, and conceptually rigorous reflection. The chapter argues that the reflection defense is misguided: Five studies (N>1800) are presented, showing that people make the same judgments when they are primed to engage in careful reflection as they do in the conditions (...) standardly used by experimental philosophers.

This essay examines the possibility that phenomenological laws might be implemented by a computational mechanism by carefully analyzing key passages from the Prolegomena to Pure Logic. Part I examines the famous Denkmaschine passage as evidence for the view that intuitions of evidence are causally produced by computational means. Part II connects the less famous criticism of Avenarius & Mach on thought-economy with Husserl's 1891 essay 'On the Logic of Signs (Semiotic).' Husserl is shown to reaffirm his earlier opposition to associationist (...) (Humean) and adaptationist (Darwinian) explanations of our thought-machine on the ground that they cannot reconstruct the notion of truth and its syntactic mental preservation in symbolic thought-trains. Part III reveals Husserl's interesting commitment to the idea that descriptive sciences necessarily transform into explanatory sciences on pain of contradicting the essence of science as a rational ideal. Since explanation in relation to phenomenology means causal explanation, and causal explanation in the form of the Denkmaschine accounts for phenomenological intuition, it is inferred that the rationally compelling ideal of explanatory science requires a computationalist reading of the subsequent logical investigations.

The basic kinds of physical causality that are foundational for other kinds of causality involve objects and the causal relations between them. These interactions do not involve events. If events were ontologically significant entities for causality in general, then they would play a role in simple mechanical interactions. But arguments about simple collisions looked at from different frames of reference show that events cannot play a role in simple mechanical interactions, and neither can the entirely hypothetical causal relations between events. (...) These arguments show that physics, which should be authoritative when it comes to the metaphysics of causality, gives no reasons to believe that events are causal agents. Force relations and some cases of energy-momentum transfer are examples of causal relations, with forces being paradigmatic in the macroscopic world, though it is conceivable that there are other kinds of causal relation. A relation between two objects is a causal relation if and only if when it is instantiated by the two objects there is a possibility that the objects that are the terms of the relation could change. The basic metaphysics of causality is about objects, causal relations, changes in objects, and a causal primitive. The paper also includes a discussion of the metaphysics of forces and a discussion of the metaphysics of energy and momentum exchanges. (shrink)

Although logical positivism had been known before World War II, it was introduced into academic philosophy in Japan only after it. In this process, the US philosophers who came to Japan in order to participate in American Studies Seminar played an important role. The first generation of Japanese analytic philosophers, who were born in the 1920s and 1930s, began to have some influence in the 1960s, and some of them published original works of high quality in the 1970s. The second (...) generation of analytic philosophers were born in the 1940s and 1950s. They began to teach in the 1970s and 1980s, and went on to publish papers and books in analytic philosophy. For many years, analytic philosophy had been known as kagaku tetsugaku, which may mean either philosophy of science or scientific philosophy. It had been frequently criticized as “non-philosophy.” Analytic philosophy, however, has changed the style of philosophical discussion and made it possible to form a language that is sufficient to express philosophical ideas and arguments in an intelligible way.

Aristotle’s solution to Zeno’s arrow paradox differs markedly from the so called at-at solution championed by Russell, which has become the orthodox view in contemporary philosophy. The latter supposes that motion consists in simply being at different places at different times. It can boast parsimony because it eliminates velocity from the ontology. Aristotle, by contrast, solves the paradox by denying that the flight of the arrow is composed of instants; rather, on my reading, he holds that the flight is a (...) unity which is ontologically prior to the temporal parts that may be abstracted from it. I label this position temporal holism; and an entity that is ontological prior to its temporal parts lasting. Lasting, I argue, is the key to Aristotle’s solution to the arrow paradox, but it has received insufficient attention in the relevant literature. I therefore set out here to investigate lasting and highlight its major role in Aristotle’s metaphysics more broadly, and in his solution to other problems of change. I show, too, how lasting within a contemporary context underwrites a parsimonious and intuitive solution to the arrow paradox that retains instantaneous velocity, and hence solves a problem for those who think velocity is required within the ontology to underwrite certain causal roles.

Recent philosophical work on causation has focused on distinctions across types of causal relationships. This paper argues for another distinction that has yet to receive attention in this work. This distinction has to do with whether causal relationships have “material continuity,” which refers to the reliable movement of material from cause to effect. This paper provides an analysis of material continuity and argues that causal relationships with this feature are associated with a unique explanatory perspective, are studied with distinct causal (...) investigative methods, and provide different types of causal control over their effects.

Materialism in the philosophy of mind — materialismPM — is the view that everything mental is material (or, equivalently, physical). Consciousness — pain, emotional feeling, sensory experience, and so on — certainly exists. So materialismPM is the view that consciousness is wholly material. It has, historically, nothing to do with denial of the existence of consciousness. Its heart is precisely the claim that consciousness — consciousness! — is wholly material. [2] ‘Physicalism’, the view introduced by members of the Vienna Circle (...) in the late 1920s, also has nothing to do with denial of the existence of consciousness. [3] Recently the words ‘materialism’ and ‘physicalism’ have come to be treated as synonymous, and as names for a position in the philosophy of mind that does involve denial of the existence of consciousness. They’ve been used to name a position that (i) directly rejects the heart of materialism (materialismPM) and (ii) is certainly false. This is a pity, because they’re good terms for a view that is very likely true. (shrink)

The time-lag argument seems to put some pressure on naïve realism to agree that seeing must happen simultaneously with what is seen; meanwhile, a wide-accepted empirical fact suggests that light takes time to transmit from objects at a distance to perceivers—which implies what is seen happened before seeing, and, accordingly, naïve realism must be false. In this paper, I will, first of all, show that the time-lag argument has in fact involves a misunderstanding concept of simultaneity: according to Special Relativity, (...) simultaneity is a matter of convention rather than a matter of fact, so, in principle, we can stipulate a perceptual conception of simultaneity, according to which what is seen is simultaneous with seeing. Secondly, the generalized time-lag argument has a mistaken view on the perceived events and perceiving; it has a doubtful assumption that these events are momentary in the mathematical sense. Such idealization is the main reason why we have the intuition that the time-lag effect of perceiving is in conflict with our ordinary perceptual experiences. Finally, I argue that the naïve realist account of the perceptual relation is a nontemporal constitutive relation; and hence naïve realism is compatible with the claim that we can perceive things as they were, and it should not be weakened by the time-lag argument.

What determines the meaning of a context-sensitive expression in a context? It is standardly assumed that, for a given expression type, there will be a unitary answer to this question; most of the literature on the subject involves arguments designed to show that one particular metasemantic proposal is superior to a specific set of alternatives. The task of the present essay will be to explore whether this is a warranted assumption, or whether the quest for the one true metasemantics might (...) be a Quixotic one. We argue that there are good reasons—much better than are commonly appreciated—for thinking the latter, but that there nevertheless remains significant scope for metasemantic theorizing. We conclude by outlining our preferred option, metasemantic pluralism. (shrink)

Semantic relativism is the view that the truth-value of some types of statements can vary depending on factors besides possible worlds and times, without any change in their propositional content. It has grown increasingly popular as a semantic theory of several types of statements, including statements that attribute knowledge of a proposition to a subject (knowledge attributions). The ways of knowing claim is the view that perception logically implies knowledge. In my “Semantic Relativism and Ways of Knowing” (2019) I argued (...) that a relativist semantics for knowledge attributions is incompatible with the ways of knowing claim. I suggested that this incompatibility depends on some basic features of the logic of relativist semantics, and therefore can be shown to generalise beyond the discussion of knowledge attributions to semantic relativism more broadly. Here I make this generalisation. I demonstrate that for any proposition p expressed by a statement that does not have a relativist semantics, and for any proposition q expressed by a statement that does have a relativist semantics, p fails to logically imply q. I explain why this happens, discuss some of its philosophical consequences, and consider a way to modify relativist semantics to avoid it. I conclude that semantic relativism raises interesting philosophical questions that have gone largely unnoticed in discussions of this view until now. (shrink)

No presente trabalho, vamos abordar algumas das questões essenciais sobre o imaginário coletivo e suas relações com a realidade e a verdade. Devemos encarar esse assunto em uma estrutura conceptual, seguida pela análise factual correspondente às realidades comportamentais demonstráveis. Adotaremos não apenas a metodologia, mas principalmente os princípios e proposições da filosofia analítica, que com certeza serão evidentes ao longo do estudo e podem ser identificados pelos recursos descritos por Perez[1] : Rabossi (1975) defende a ideia de que a filosofia (...) analítica pode ser identificada considerando-se certas semelhanças familiares. Ele sugere os seguintes traços familiares: uma atitude positiva em relação ao conhecimento científico; uma atitude cautelosa em relação à metafísica; uma concepção da filosofia como uma tarefa conceptual, que toma a análise conteudo como um método; uma estreita relação entre linguagem e filosofia; uma preocupação em buscar respostas argumentativas para problemas filosóficos, e procura de clareza conceptual. Esses conceitos centrais envolvem conteúdos culturais, sociais, religiosos, científicos, filosóficos, morais e políticos, pertencentes à existência individual e coletiva de cada um de nós. Neste artigo, não discutiremos nem demonstraremos. Nosso objetivo não é o de sistematicamente criticar ou evidenciar qualquer coisa, de qualquer maneira. O presente trabalho se baseia na reflexão analítica. Apenas especularemos da maneira mais abrangente e profunda que pudermos e expressaremos os resultados de nossos pensamentos. Não obstante a natureza multidisciplinar do assunto e a abertura metodológica para aceitar contribuições de qualquer campo da ciência, este trabalho pertence ao objetivo da psicologia e ontologia ou, em outros termos, da psicologia social e ontológica. A metodologia livre que norteia tais reflexões abrange e leva em consideração tudo o que se aproxima da coerência com a epistemologia filosófica e psicológica. Essa metodologia não busca alcançar evidências, mas apenas procura a inter-relação entre evidências já existentes, de qualquer natureza e magnitude, inferindo um significado coerente para as coisas reais. Muitos dos grandes pensadores, a qualquer momento, nunca procuraram demonstrações, teorizações ou sistematizações. Esses pensadores apenas pensavam, meditavam e com a iluminação de sua humildade podiam se aproximar da verdade. Eles serão nossa referência e o exemplo a ser seguido. Com certeza, não encontraremos a verdade, mas podemos ter certeza de alguma coisa: em muitos momentos, chegaremos perto da verdade e, em todos os momentos, estaremos nos afastando da inverdade e da mentira. O escopo principal deste estudo é observar como alguns dos atributos evolutivos essenciais da humanidade, como criatividade, imaginação e associação, podem se tornar uma doença perigosa, abrigada nas sombras enevoadas da inteligência.

This chapter presents a typology of the different kinds of inductive inferences we can draw from our evidence, based on the explanatory relationship between evidence and conclusion. Drawing on the literature on graphical models of explanation, I divide inductive inferences into (a) downwards inferences, which proceed from cause to effect, (b) upwards inferences, which proceed from effect to cause, and (c) sideways inferences, which proceed first from effect to cause and then from that cause to an additional effect. I further (...) distinguish between direct and indirect forms of downwards and upwards inferences. I then show how we can subsume canonical forms of inductive inference mentioned in the literature, such as inference to the best explanation, enumerative induction, and analogical inference, under this typology. Along the way, I explore connections with probability and confirmation, epistemic defeat, the relation between abduction and enumerative induction, the compatibility of IBE and Bayesianism, and theories of epistemic justification.

This paper argues for a sufficient evidence condition on knowledge and I argue that there is no belief condition on knowledge.

It is increasingly common for philosophers to rely on the notion of an idealised listener when explaining how the semantic values of context-sensitive expressions are determined. Some have identified the semantic values of such expressions, as used on particular occasions, with whatever an appropriately idealised listener would take them to be. Others have argued that, for something to count as the semantic value, an appropriately idealised listener should be able to recover it. Our aim here is to explore the range (...) of ways that such idealisation might be worked out, and then to argue that none of these results in a very plausible theory. We conclude by reflecting on what this negative result reveals about the nature of meaning and responsibility. (shrink)

En este ensayo exploramos una perspectiva epistemológica en la que el elemento social y colectivo del conocimiento juega un papel fundamental en la explicación de su producción y transmisión. Primero presentamos y criticamos una posición individualista que ha sido dominante en la epistemología contemporánea y cuyas raíces pueden trazarse, al menos, hasta Descartes. Posteriormente introducimos y defendemos nuestra propia mirada, una en la que el conocimiento es un proceso constituido por un conjunto de actividades y prácticas que tiene un carácter (...) material.

This thesis articulates an analytic version of the ontology of idealism, according to which universal phenomenal consciousness is all there ultimately is, everything else in nature being reducible to patterns of excitation of this consciousness. The thesis’ key challenge is to explain how the seemingly distinct conscious inner lives of different subjects—such as you and me—can arise within this fundamentally unitary phenomenal field. Along the way, a variety of other challenges are addressed, such as: how we can reconcile idealism with (...) the fact that we all inhabit a common external world; why this world unfolds independently of our personal volition or imagination; why there are such tight correlations between measured patterns of brain activity and reports of experience; etc. The core idea of this thesis can be summarized thus: we, as well as all other living organisms, are dissociated alters of universal phenomenal consciousness, analogously to how a person with Dissociative Identity Disorder (DID) manifests multiple disjoint centers of subjectivity also called ‘alters.’ We, and all other living organisms, are surrounded by the transpersonal phenomenal activity of universal consciousness, which unfolds beyond the dissociative boundary of our respective alter. The inanimate world we perceive around us is the extrinsic appearance—i.e. the phenomenal image imprinted from across our dissociative boundary—of this activity. The living organisms we share the world with are the extrinsic appearances of other alters. (shrink)

I present a puzzle about belief and credence, which takes the form of three independently supported views that are mutually inconsistent. The first is the view that S has a modal belief that p (e.g., S believes that probably-p) if and only if S has a corresponding credence that p. The second is the view that S believes that p only if S has some credence that p. The third is the view that, possibly, S believes that p without a (...) modal belief that p. [Word Count: 85].

Modal epistemologists parse modal conditions on knowledge in terms of metaphysical possibilities or ways the world might have been. This is problematic. Understanding modal conditions on knowledge this way has made modal epistemology, as currently worked out, unable to account for epistemic luck in the case of necessary truths, and unable to characterise widely discussed issues such as the problem of religious diversity and the perceived epistemological problem with knowledge of abstract objects. Moreover, there is reason to think that this (...) is a congenital defect of orthodox modal epistemology. This way of characterising modal epistemology is however optional. It is shown that one can non-circularly characterise modal conditions on knowledge in terms of epistemic possibilities, or ways the world might be for the target agent. Characterising the anti-luck condition in terms of epistemic possibilities removes the impediment to understanding epistemic luck in the case of necessary truths and opens the door to using these conditions to shed new light on some longstanding epistemological problems.

It is a simple truth about the English language that we can see or hear or feel what others are thinking or feeling. But it is tempting to think that there is a deeper sense in which we cannot really see or hear or feel these things at all. Rather, what is involved must be a matter of inference or interpretation, for instance. In these remarks, I argue against a variety of ways in which that thought, the thought that we (...) cannot really see or hear or feel what others are thinking or feeling, might be developed.

There is a long-standing view in epistemology that perception is a way of knowing. There is a less long-standing but increasingly popular view that knowledge attributions have a relativist semantics. I discuss three things here. First, I show that it is a consequence of the logic of RKA that WOK and RKA are incompatible. Second, I argue that, even if WOK is incompatible with the main rivals to RKA, this is not a consequence of the logics of these views. RKA (...) comes with a hitherto unobserved philosophical consequence that its main rivals do not come with. Third, I consider some responses to the effect that it does not matter that RKA comes with this consequence, and argue that they are all unsatisfactory as they stand. I conclude that, at the very least, the onus is placed on relativists to engage with more epistemology than they currently do to show that we do not need to worry about the incompatibility of WOK and RKA. I conclude with some suggestions about the broader relevance and implications of this paper. (shrink)

There is something puzzling about statistical evidence. One place this manifests is in the law, where courts are reluctant to base affirmative verdicts on evidence that is purely statistical, in spite of the fact that it is perfectly capable of meeting the standards of proof enshrined in legal doctrine. After surveying some proposed explanations for this, I shall outline a new approach – one that makes use of a notion of normalcy that is distinct from the idea of statistical frequency. (...) The puzzle is not, however, merely a legal one. Our unwillingness to base beliefs on statistical evidence is by no means limited to the courtroom, and is at odds with almost every general principle that epistemologists have proposed as to how we ought to manage our beliefs.

It is commonly accepted, after Frege, that identity statements like “Tully is Cicero” differ from statements like “Tully is Tully”. For the former, unlike the latter, are informative. One way to deal with the information problem is to postulate that the terms ‘Tully’ and ‘Cicero’ come equipped with different informative values. Another approach is to claim that statements like these are of the subject/predicate form. As such, they should be analyzed along the way we treat “Tully walks”. Since proper names (...) can appear in predicative position we could go as far as to dismiss the sign of identity altogether, some told us. I will try to discuss the advantages and/or disadvantages of this approach and investigate whether Frege’s view that the ‘is’ of identity must be distinguished from the ‘is’ of predication can be reconciled with the fact that names can appear in predicative position.

According to a captivating picture, epistemic justification is essentially a matter of epistemic or evidential likelihood. While certain problems for this view are well known, it is motivated by a very natural thought—if justification can fall short of epistemic certainty, then what else could it possibly be? In this paper I shall develop an alternative way of thinking about epistemic justification. On this conception, the difference between justification and likelihood turns out to be akin to the more widely recognised difference (...) between ceteris paribus laws and brute statistical generalisations. I go on to discuss, in light of this suggestion, issues such as classical and lottery-driven scepticism as well as the lottery and preface paradoxes. (shrink)

I argue that knowledge is a particular kind of concept known as a thick concept. Examples of thick concepts include courage, generosity, loyalty, brutality, and so forth. These concepts are commonly said to combine both evaluation and description, and one of the main goals of this dissertation is to provide a new account of how a thick concept combines these elements. It is argued that thick concepts are semantically evaluative, and that they combine evaluation and description in a way similar (...) to that of concepts like good qua dancer and bad qua violinist. In the final chapter, this basic idea is applied to the concept of knowledge. There, the concept of knowledge is analyzed in terms of good qua belief. The upshot is that two central epistemological problems—the Gettier Problem and the Value Problem—can be resolved. (shrink)

Scepticism is sometimes expressed about whether there is any interesting problem of other minds. In this paper I set out a version of the conceptual problem of other minds which turns on the way in which mental occurrences are presented to the subject and situate it in relation to debates about our knowledge of other people's mental lives. The result is a distinctive problem in the philosophy of mind concerning our relation to other people.

It is generally agreed that Galileo’s distinctive place in the history of science is due to the power of his method, and that, in general terms, this consists in an effective combination of mathematics and physical experiment. In attempting to be more specific, some authors have assigned a particular method to Galileo as either new or a unique adaptation of a traditional method, e.g. hypothetico-deduction, the method of analysis, or ex suppositione. William Wallace, for example, has argued that by the (...) time of the «Two New Sciences» (1638) Galileo had fashioned his own version of ex suppositione, combining elements of the Archimedean and Aristotelian traditions into a distinct two-stage mode of reasoning of his own creation. We shall have reason to comment upon this below. (shrink)

While it is widely accepted that human vision represents objects, it is less clear which of the various philosophical notions of ‘object’ adequately characterizes visual objects. In this paper, I show that within contemporary cognitive psychology visual objects are characterized in two distinct, incompatible ways. On the one hand, models of visual organization describe visual objects in terms of combinations of features, in accordance with the philosophical bundle theories of objects. However, models of visual persistence apply a notion of visual (...) objects that is more similar to that endorsed in philosophical substratum theories. Here I discuss arguments that might show either that only one of the above notions of visual objects is adequate in the context of human vision, or that the category of visual objects is not uniform and contains entities properly characterized by different philosophical conceptions.

Historians of philosophy commonly regard as antipodal Bertrand Russell and Edmund Husserl, the founding fathers of analytic philosophy and phenomenology. This paper, however, establishes that during a formative phase in both of their careers Russell and Husserl shared a range of seminal ideas. In particular, the essay adduces clear cases of family resemblance between Husserl’s and Russell’s philosophy during their middle period, which spanned the years 1905 through 1918. The paper thus challenges the received view of Husserl’s relation to early (...) analytic philosophy and this by pursuing two strategies of exposition. One involves comparing Husserl with Russell, and not, as has been the usual practice, with Frege. The other, which follows the first, foregrounds Husserl’s thinking vis-à-vis Russell’s from 1905 onward, a move that constitutes a break with what has become the standard approach of emphasising the relatedness of Husserl of the Logical Investigations (1900/1) to analytic philosophy. Moreover, this approach discloses two chief grounds of relatedness between the middle Husserl and the middle Russell. One is their shared interest in exploring philosophical “fundamentals”. The second consists of common elements shared by their epistemologies and philosophies of mind. (shrink)

The paper argues that knowledge is not closed under logical inference. The argument proceeds from the openness of evidential support and the dependence of empirical knowledge on evidence, to the conclusion that knowledge is open. Without attempting to provide a full-fledged theory of evidence, we show that on the modest assumption that evidence cannot support both a proposition and its negation, or, alternatively, that information that reduces the probability of a proposition cannot constitute evidence for its truth, the relation of (...) evidential support is not closed under known entailment. Therefore the evidence-for relation is deductively open regardless of whether evidence is probabilistic or not. Given even a weak dependence of empirical knowledge on evidence, we argue that empirical knowledge is also open. On this basis, we also respond to the strongest argument in support of knowledge closure. Finally, we present a number of significant benefits of our position, namely, offering a unified explanation for a range of epistemological puzzles. (shrink)

There is a traditional conception of knowledge but it is not the Justified True Belief analysis Gettier attacked. On the traditional view, knowledge consists in having a belief that bears a discernible mark of truth. A mark of truth is a truth-entailing property: a property that only true beliefs can have. It is discernible if one can always tell that a belief has it, that is, a sufficiently attentive subject believes that a belief has it if and only if it (...) has it. Requiring a mark of truth makes the view infallibilist. Requiring it to be discernible makes the view internalist. I call the view Classical Infallibilism. (shrink)

The issue whether there is any necessary connection between time and change turns, I argue, on the problem of what constitutes an accurate measurement of how much time passes. Given a plausible hypothesis about how time is measured, Shoemaker’s well known argument that time can pass without change can be seen to be unsound. But Shoemaker’s conclusion is not therefore false. The same hypothesis about time measurement supports a revised version of Shoemaker’s argument, and the revised argument does establish that (...) the passage of a quantity of time does not require that change occur during that time. Though Shoemaker’s conclusion is vindicated, it does not follow that there is no necessary connection at all between time and change. On the contrary, there is a connection which is simply of a different kind from the one Shoemaker had in mind. (shrink)

The validity of three premises, set as foundational pillars of modern sociological approach to science, is contested, namely: the postulate, stating that science is devoid of whatever generis specifical; it is liable to the usual empirical study; the practicing scientist's self-reflexive judgements must be disbelieved and rejected. Contrariwise, the ignored so far quaint nature of knowledge, escaping even from the elementary empirical treating - discernment and observation - is revealed and demonstrated. This peculiar nature requires, accordingly, a specific meta-cognitive dealing (...) for positing it as 'empirical object', unfortunately missed still by the Strong Programme. The inadequate approach adopted led to a substitution of 'scientific' for common knowledge. The tacit thus far alternative, setting the foundations of meta-science, is suggested. (shrink)

According to David Lewis, the predicate ‘knows’ is context-sensitive in the sense that its truth conditions vary across conversational contexts, which stretch or compress the domain of error possibilities to be eliminated by the subject’s evidence. Our concern in this paper is to thematize, assess, and overcome within a neo-Lewisian contextualist project two important mismatches between our use of ‘know’ in ordinary life and the use of ‘know’ by ‘Lewisian’ ordinary speakers. The first mismatch is that Lewisian contextualism still overgenerates (...) the error possibilities which cannot be ignored in a given context, since it is oblivious to the distinction between ‘invented’ and ‘discovered’ possibilities. The second mismatch is a full-scale one: an adequate account of knowledge attribution is not exhausted by the subject’s negative capacity of pruning branches off the tree of counterpossibilities. We therefore introduce a new vector of value, which explains how ‘know’ comes in degrees: the satisfaction of ‘know better’ is made to depend on the capacity of imagining possibilities connected in a relevant way with the subject’s beliefs. (shrink)

This paper argues for an overlooked dimension in the metaphysical microstructure of knowledge. The connection between knowledge and truth is even deeper than generally acknowledged. Knowledge, I argue, supervenes not only on a specific (namely modal) relation between the proposition p’s truth and an agent’s belief that p, but also on specific relations between the proposition’s truthmaker and the belief’s justification-maker. S knows that p only if the states of affairs referred to by S’s reasons for believing that p are (...) identical with, causally related to, or grounded in the states of affairs that make p true.

In this paper I offer a unified causal account of natural kinds. Using as a starting point the widely held view that natural kind terms or predicates are projectible, I argue that the ontological bases of their projectibility are the causal properties and relations associated with the natural kinds themselves. Natural kinds are not just concatenations of properties but ordered hierarchies of properties, whose instances are related to one another as causes and effects in recurrent causal processes. The resulting account (...) of natural kinds as clusters of core causal properties that give rise to clusters of derivative properties enables us to distinguish genuine natural kinds from non-natural kinds. For instance, it enables us to say why some of the purely conventional categories derived from the social domain do not correspond to natural kinds, though other social categories may. (shrink)

Panpsychism is the view that every concrete and unified thing has some form of phenomenal consciousness or experience. It is an age-old doctrine, which, to the surprise of many, has recently taken on new life. In philosophy of mind, it has been put forth as a simple and radical solution to the mind–body problem (Chalmers 1996, 2003;Strawson 2006; Nagel 1979, 2012). In metaphysics and philosophy of science, it has been put forth as a solution to the problem of accounting for (...) the intrinsic nature of the physical itself (Strawson 2006, Seager 2006). In this thesis, I show that panpsychism can also be defended on the basis of an argument from our (arguable) acquaintance with the nature of causation in agency. This argument has made frequent appearances throughout the history of philosophy, with philosophers such as Leibniz, Schopenhauer and James, and I construct and defend an updated version of it. Furthermore, I offer a solution to the combination problem: how can complex (human and animal-type) consciousness result from simple (fundamental particle-type) consciousness? This is generally regarded as the most serious problem facing contemporary panpsychism. I propose that mental combination can be construed as kind causal process culminating in a fusion, and show how this avoids the main difficulties with accounting for mental combination. (shrink)

Der Beitrag beleuchtet einen bisher kaum gewürdigten Grund dafür, dass die Gettier-Debatte nicht zu einer systematisch verbesserten Analyse des Wissensbegriffs geführt hat. Es wird die These entwickelt und verteidigt, dass diejenigen Komplikationen, die einen Gettierfall zu einem solchen machen, sich stets in den blinden Flecken der Situationsrepräsentation des epistemischen Subjekts befinden. Diese These ist in die metaphilosophische Fragestellung eingebettet, was das Gettierproblem uns über das Verhältnis von sprachlichen Intuitionen und Begriffsanalysen lehrt. Es gibt unter kompetenten Sprechern beträchtliche Einmütigkeit darüber, dass (...) paradigmatische Gettierfälle als Fälle von Nichtwissen zu klassifizieren sind, aber ungleich weniger Einigkeit darüber, ob und wie die klassische Analyse des Wissensbegriffs verbessert werden kann. Zu der Frage, warum es so schwer ist, konvergierende sprachliche Intuitionen über Einzelfälle in eine gettierfallsichere allgemeine Analyse zu überführen, werden folgende Thesen entwickelt: Was in Gettierfällen konfligiert, sind nicht Analyse und Intuition als solche, sondern die Charakterisierung eines Situationstyps und die Beurteilung einer einzelnen Situation angesichts einer bestimmten Gettierkomplikation. Die Aufgabe, eine allgemeine Beschreibung der mit Wissen unvereinbaren Komplikationen zu geben, geht weit über die kompetente Beurteilung von Einzelfällen hinaus. Möglicherweise ist sie unlösbar, weil das wörtliche Zutreffen der Beschreibung einer epistemischen Situation niemals garantieren kann, dass sich in den Leerstellen der Beschreibung keine Gettierkomplikation verbirgt.

The growing literature on philosophical thought experiments has so far focused almost exclusively on the role of thought experiments in confirming or refuting philosophical hypotheses or theories. In this paper we draw attention to an additional and largely ignored role that thought experiments frequently play in our philosophical practice: some thought experiments do not merely serve as means for testing various philosophical hypotheses or theories, but also serve as facilitators for conceiving and articulating new ones. As we will put it, (...) they serve as ‘heuristics for theory discovery’. Our purpose in the paper is two-fold: to make a case that this additional role of thought experiments deserves the attention of philosophers interested in the methodology of philosophy; to sketch a tentative taxonomy of a number of distinct ways in which philosophical thought experiments can aid theory discovery, which can guide future research on this role of thought experiments.

Skeptical puzzles and arguments often employ knowledge-closure principles . Epistemologists widely believe that an adequate reply to the skeptic should explain why her reasoning is appealing albeit misleading; but it’s unclear what would explain the appeal of the skeptic’s closure principle, if not for its truth. In this paper, I aim to challenge the widespread commitment to knowledge-closure. But I proceed by first examining a new puzzle about failing to know—what I call the New Ignorance Puzzle . This puzzle resembles (...) to the Old Ignorance Puzzle , although it does not involve a closure principle. It instead centers on the standard view of ignorance, a highly intuitive principle stating that ignorance is merely a failure to know. In Sects. 2 and 3, I argue that the best way to solve the New Ignorance Puzzle is to reject the standard view of ignorance and to explain away its appeal via conversational implicature. I then use this solution to the New Ignorance Puzzle as a way of explaining why knowledge-closure principles would seem true, and why abominable conjunctions would seem abominable, even if such principles were false . The upshot is a new way of explaining why the skeptic’s reasoning is appealing albeit misleading. (shrink)

This paper advances the view that the history of philosophy is both a kind of history and a kind of philosophy. Through a discussion of some examples from epistemology, metaphysics, and the historiography of philosophy, it explores the benefit to philosophy of a deep and broad engagement with its history. It comes to the conclusion that doing history of philosophy is a way to think outside the box of the current philosophical orthodoxies. Somewhat paradoxically, far from imprisoning its students in (...) outdated and crystallized views, the history of philosophy trains the mind to think differently and alternatively about the fundamental problems of philosophy. It keeps us alert to the fact that latest is not always best, and that a genuinely new perspective often means embracing and developing an old insight. The upshot is that the study of the history of philosophy has an innovative and subversive potential, and that philosophy has a great deal to gain from a long, broad, and deep conversation with its history.

In this paper I distinguish two ways of raising a sceptical problem of others' minds: via a problem concerning the possibility of error or via a problem concerning sources of knowledge. I give some reason to think that the second problem raises a more interesting problem in accounting for our knowledge of others’ minds and consider proposed solutions to the problem.

Guided by key insights of the four great philosophers mentioned in the title, here, in review of and expanding on our earlier work (Burchard, 2005, 2011), we present an exposition of the role played by language, & in the broader sense, λογοζ, the Logos, in how the CNS, the brain, is running the human being. Evolution by neural Darwinism has been forcing the linguistic nature of mind, enabling it to overcome & exploit the cognitive gap between an animal and its (...) world by recognizing environmental structures. Our work was greatly influenced by Heidegger’s lecture notes on metaphysics (Heidegger, 1935). We found agreement with recent progress in neuroscience, but also mathematical foundations of language theory, equating Logos with the mathematical concept of structure. The mystery of perception across the gap is analyzed as radiation and molecules impinging on sensory neurons that carry linguistic information about gross environmental structures, and only remotely about the physical reality of elementary particles. The most important logical brain function is Ego or Self, guiding the workings of the brain as a logos machine. Ego or Self operates from neurons in frontopolar cortex with global receptive fields. The logos machine can function only by availing itself of global context, its internally stored noumenal cosmos NK, and the categorical-conceptual apparatus CCA, updated continually through the neural default mode network (Raichle, 2005). In the Transcendental Deduction, Immanuel Kant discovered that Ego or Self is responsible for conscious control in perception relying on concepts & categories for a fitting percept to be incorporated intoNK. The entire CNS runs as a “movie-in-the-brain” (Parvizi & Damasio, 2001), at peak speed processing simultaneously in a series of cortical centers a stack of up to twelve frames in gamma rhythm of 25 ms intervals. We equate global context, or NK, with our human world, Heidegger’s Dasein being-in-the-world, and are able to demonstrate that the great philosopher in EM parallels neuro-science concerning the human mind.

Nearly all success is due to some mix of ability and luck. But some successes we attribute to the agent’s ability, whereas others we attribute to luck. To better understand the criteria distinguishing credit from luck, we conducted a series of four studies on knowledge attributions. Knowledge is an achievement that involves reaching the truth. But many factors affecting the truth are beyond our control and reaching the truth is often partly due to luck. Which sorts of luck are compatible (...) with knowledge? We find that knowledge attributions are highly sensitive to lucky events that change the explanation for why a belief is true. By contrast, knowledge attributions are surprisingly insensitive to lucky events that threaten but ultimately fail to change the explanation for why a belief is true. These results shed light on our concept of knowledge, help explain apparent inconsistencies in prior work on knowledge attributions, and constitute progress toward a general understanding of the relation between success and luck.
