ABSTRACT: Sellars formulated his thesis of 'psychological nominalism' in two very different ways: (1) most famously as the thesis that 'all awareness of sorts…is a linguistic affair', but also (2) as a certain thesis about the 'psychology of the higher processes'. The latter thesis denies the standard view that relations to abstract entities are required in order to explain human thought and intentionality, and asserts to the contrary that all such mental phenomena can in principle ‘be accounted for causally' without (...) any use of normative terms in the explanation. Recent 'Hegelian Sellarsians' such as Rorty, McDowell, and Brandom have argued that the holistic, normative themes in (1) support various non-realist or rather (German) 'idealist but common-sense realist' outlooks. By contrast, Sellars' own defenses of (2) reveal psychological nominalism itself to be a naturalistic empiricism intended to sustain the normative-holistic themes in (1) within an exhaustively scientific naturalist conception of reality.

Wie denkt Dogen (1200-1253) Sprache im Horizont der sprachkritischen Tradition des Zenbuddhismus? Die vorliegende Studie widmet sich dieser Frage und rekonstruiert umfassend das Sprachdenken des philosophisch fruchtbarsten Autors der japanischen Vormoderne. Dazu wählt der Autor einen doppelten Zugang: zum einen rezeptionsgeschichtlich unter Einschluss von Philosophen des modernen Japans, zum anderen systematisch mithilfe der Symboltheorie Ernst Cassirers in der Theoretisierung eines adäquaten Sprachbegriffs. So verschränken sich mit Interpretationen zum Hauptwerk Dogens, dem Shobogenzo, Außen- und Innenperspektive auf ein zenbuddhistisches Sprachdenken und erweisen (...) es in seiner Kommensurabilität zum philosophischen Diskurs.

Special issue: "Reflecting on the Legacy of C.I. Lewis: Contemporary and Historical Perspectives on Modal Logic".

Verificationism has had a bad press for many years. The view that the meaning of our words is bound up with the discernible difference it would make if what we say, think or write were true or false, nowadays is scorned as “positivist” though it was shared by eminent empiricists and pragmatists. This paper seeks to sort through some of the complexities of what is often portrayed as an unduly simplistic conception. I begin with an overview of its main logical (...) empiricist varieties before considering which aspects of it fall victim to which of the three major types of objection that have been raised against it. I will conclude that what is left standing is a modest proposal that seems worth further investigation. (shrink)

Coherence and correspondence are classical contenders as theories of truth. In this paper we examine them instead as interacting factors in the dynamics of belief across epistemic networks. We construct an agent-based model of network contact in which agents are characterized not in terms of single beliefs but in terms of internal belief suites. Individuals update elements of their belief suites on input from other agents in order both to maximize internal belief coherence and to incorporate ‘trickled in’ elements of (...) truth as correspondence. Results, though often intuitive, prove more complex than in simpler models (Hegselmann & Krause 2002, 2006; Grim, Singer, Reade & Fisher 2015). The optimistic finding is that pressures toward internal coherence can exploit and expand on small elements of truth as correspondence is introduced into epistemic networks. Less optimistic results show that pressures for coherence can also work directly against the incorporation of truth, particularly when coherence is established first and new data is introduced later.

This Open Access book addresses the age-old problem of infinite regresses in epistemology. How can we ever come to know something if knowing requires having good reasons, and reasons can only be good if they are backed by good reasons in turn? The problem has puzzled philosophers ever since antiquity, giving rise to what is often called Agrippa's Trilemma. The current volume approaches the old problem in a provocative and thoroughly contemporary way. Taking seriously the idea that good reasons are (...) typically probabilistic in character, it develops and defends a new solution that challenges venerable philosophical intuitions and explains why they were mistakenly held. Key to the new solution is the phenomenon of fading foundations, according to which distant reasons are less important than those that are nearby. The phenomenon takes the sting out of Agrippa's Trilemma; moreover, since the theory that describes it is general and abstract, it is readily applicable outside epistemology, notably to debates on infinite regresses in metaphysics.

Among the deeper strata of Rorty’s philosophy is what I call his aversion to normative violence. Normative violence occurs when some specific group presents itself as having a privileged relation to reality. The alternative to normative violence is recognizing that cultural politics has priority over ontology. I trace this Rortyan idea to its origins in Nietzsche and Sellars. Rorty’s contribution is to combine Nietzsche on the death of God and Sellars on the Myth of the Given. However, I conclude with (...) a suggestion that Rorty ultimately goes too far in thinking that avoiding normative violence requires abstaining from metaphysics and epistemology as such. (shrink)

This paper responds to the generous comments by Alexander Klein and Cheryl Misak on my “American Pragmatism and the Vienna Circle: The Early Years”. First, besides offering some clarification of my original thesis, I argue that Jerusalem was not liable to the anti-Spencerian criticisms by James that Klein adduces in the course of defending James against the charge of psychologism. Then I investigate the impact of Wittgenstein’s Ramsey-derived pragmatism, importantly foregrounded by Misak, on the Vienna Circle and argue that it (...) was mainly limited to Schlick but not recognized as pragmatist, also leaving unaffected the impact of James’s pragmatism on Frank, Hahn and Neurath specified in my original paper. That said, Klein’s and Misak’s comments add significantly to our understanding of long-neglected transatlantic philosophical connections in the early twentieth century. (shrink)

Arthur Pap was not quite a Logical Empiricist. He wrote his dissertation in philosophy of science under Ernest Nagel, and he published a textbook in the philosophy of science at the end of his tragically short career, but most of his work would be classified as analytic philosophy. More important, he took some stands that went against Logical Empiricist orthodoxy and was a persistent if friendly critic of the movement. Pap diverged most strongly from Logical Empiricism in his theory of (...) a “functional a priori” in which fundamental principles of science are hardened into definitions and act as criteria for further inquiry. Pap was strongly influenced by the pragmatists C. I. Lewis and John Dewey in developing this alternative theory of a priori knowledge. Using Poincaré’s conventionalism as a springboard, Pap attempted to substantiate these views with examples from physics, and this was his largest foray into philosophy of science topics. Pap, as well as Lewis and Dewey, developed an alternative theory of the a priori in the 1950s that never quite took hold, despite the fact that their views are very intriguing and similar to Michael Friedman’s recent work on the constitutive a priori.

The term ‘consciousness’ is a latecomer upon the stage of Western philosophy. The ancients had no such term. Sunoida, like its Latin equivalent conscio, meant the same as ‘I know together with’ or ‘I am privy, with another, to the knowledge that’. If the prefixes sun and cum functioned merely as intensifiers, then the verbs meant simply ‘I know well’ or ‘I am well aware that’. Although the ancients did indeed raise questions about the nature of our knowledge of our (...) own perceptions and thought, and introduced the idea of an inner sense, they did not characterize the mind as the domain of consciousness. Aristotelians conceived of the mind as the array of powers that distinguish humanity from the rest of animate nature. The powers of self-movement, of perception and sensation, and of appetite, are shared with other animals. What is distinctive of humanity, and what characterizes the mind, are the powers of the intellect – of reason, and of the rational will. Knowledge of these powers is not obtained by consciousness or introspection, but by observation of their exercise in our engagement with the world around us. The mediaevals followed suit. They likewise lacked any term for consciousness, although they too indulged in reflections upon ‘inner senses’ – in the wake of Avicenna's distinguishing, arguably to excess, five such senses.

Este artigo apresenta um exame da crítica proposta por Morton White em seu artigo “Valor e obrigação em Dewey e Lewis”, em particular, a aquela voltada para o conceito de normatividade e valoração de C.I. Lewis. A crítica afirma que Lewis, ao oferecer um caráter normativo dos juízos éticos, malogra ao articular consistentemente a sua concepção ética com a sua teoria do conhecimento. Isso leva White a concluir que o pragmatista não possui uma solução para o problema fundamental da ética. (...) Argumentarei que tal conclusão é equivocada. O núcleo da minha argumentação repousa na tese de que a crítica de White se origina de uma interpretação incorreta do pragmatismo conceitualista de Lewis, falhando em reconhecer que o apriorismo pragmático é a chave para o entendimento adequado de teoria do conhecimento e para uma explicação da conexão e articulação entre valoração e normatividade no interior da abordagem de Lewis. Nesta linha, mostrarei que, muito pelo contrário, a epistemologia de Lewis destaca os desenvolvimentos éticos e normativos, revelando uma teoria naturalística de valoração que é a base na qual a normatividade emerge pragmaticamente. Sustentarei, também, que essa perspectiva oferece uma concepção profícua de valores e normas que não têm sido suficientemente exploradas; algo que confronta o ceticismo ético, podendo levar em conta o status cognitivo de valores e normas, e que recupera o caráter racional da valoração não apenas para a ética, mas, também, para o conhecimento e a ciência.

Kant’s account of cognitive judgment is sophisticated, sound and philosophically far more illuminating than is often appreciated. Key features of Kant’s account of cognitive judgment are widely dispersed amongst various sections of the Critique of Pure Reason, whilst common philosophical proclivities have confounded these interpretive difficulties. This paper characterises Kant’s account of causal-perceptual judgment concisely to highlight one central philosophical achievement: Kant’s finding that, to understand and investigate empirical knowledge we must distinguish between predication as a grammatical form of sentences, (...) statements or judgments, and predication as a cognitive act of ascribing some characteristic to some localised particular. With Kant’s finding in view, I then elucidate how we have occluded his achievement. My results are not merely interpretive, but philosophical, because they show that Kant’s account of perceptual judgment accords with – and indeed justifies – a central and sound point regarding language, thought and reference advocated by apparently unlikely philosophical comrades. These finding highlight some methodological cautions which require re-emphasis today. (shrink)

In the early chapters of Mind and the World Order, Lewis develops a theory of meaning which has interesting points of similarity with that mentalistic or propositional theory of meaning which has been rejected by Quine, in Word and Object and elsewhere. There are also interesting similarities, however, between Lewis’ theory and Quine's own naturalistic theory. In this paper, I shall concentrate on one such similarity: namely, the analogy, noticed by Quine, between the predicament formulated in his own thesis of (...) the indeterminacy of translation, and the “predicament of private worlds” in which Lewis’ theory of meaning is involved.These analogous predicaments have a bearing on the problems of the commensurability of scientific theories and of objectivity in science in general; in fact, my primary motivation in attempting to explicate the analogy between Quine's theory of meaning and Lewis’ theory is to clear the way for an assessment of Quine's position on the problem of the objectivity of theories in science.

This paper argues that the problem of the apparent conflict between freedom of action and natural causal determinism has not been properly framed, because the key premiss—the thesis of universal causal determinism—is, in the domain of human behaviour, an unjustified conjecture based on over-simplified, under-informed explanatory models. Kant's semantics of singular cognitive reference, which stands independently of his Transcendental Idealism, justifies and emphasises a quadruple distinction between causal description, causal ascription, true causal ascription and cognitively justified causal ascription. Contemporary causal (...) theories of mind, of action or of meaning do not suffice for causal ascription, and so cannot suffice for causal predication, and hence cannot justify causal determinism about human behaviour. More generally, the principle of universal causal determinism is a regulative principle governing causal inquiry and was so formulated by LaPlace. Only successful, sufficient causal explanation of particular events provides for causal knowledge of those events. Such knowledge we lack in the domain of human behaviour. Rational belief, including scientific belief, requires apportioning belief to justifying evidence; all else is conjecture or speculation, which do not justify premises of sound proofs. Causal determinism about human behaviour remains unjustified speculation, for sound Critical reasons Kant provided us in the Kritik der reinen Vernunft. In these regards, contemporary debates about these issues remain decidedly pre-Critical. (shrink)

This essay purports to be a “negative” defense of acquaintance foundationalism. It is “negative” in that I do not do much in the way of advancing novel argument for the position, nor do I extend the position very much. Rather, I focus on demonstrating that the position has the resources to overcome objections that have been proposed to it. In particular, I argue that it can overcome the dilemma proposed by Wilfrid Sellars and developed by Laurence BonJour against foundationalism, as (...) well as dilemmas proposed by Jack Lyons and Michael Bergmann targeting internalism. Acquaintance foundationalism is what I will call any theory of justification that is internalist in what may justify us, foundationalist in the structure of justification, and relies on the concept of acquaintance in justifying our basic beliefs. Internalism requires that what justifies us improves the belief from the perspective of the believing subject. Foundationalism states that the justification for all beliefs depends ultimately on basic beliefs. Finally, acquaintance is a relation between a person and other things such that these other things are before the “mind’s eye” of the subject. The general idea behind each of these dilemmas, so I will argue, is to claim that acquaintance foundationalism cannot provide epistemic reasons for basic beliefs, where epistemic reason means something that contributes to justification from the subject’s perspective. Each dilemma will ask whether the alleged justifier has some feature x. However, each dilemma contends that, whether the alleged has the feature x or not, it cannot serve as an epistemic reason. For example, BonJour will ask whether our allegedly basic beliefs are cognitive or not. He argues that if they are cognitive, they need justification, but if they are not cognitive, they cannot provide justification. Thus, no allegedly basic belief can serve as an epistemic reason. I argue that the notion of acquaintance allows us to escape such dilemmas because our states of acquaintance allow us to justify our basic beliefs without requiring justification themselves. I do so by borrowing, in part, Richard Fumerton’s theory of non-inferential justification, plus adding on a few epicycles to allow us to base our basic beliefs on our acquaintances. The first chapter sets up the issues of the dissertation: it gives context to the project, defines acquaintance foundationalism and epistemic reason, and discusses our dilemmas in broad outline. It also summarizes the rest of the essay. I use epistemic reasons in a specialized sense in the dissertation, which necessitates an extended discussion. This is the focus of chapter two. I argue that an epistemic reason is a mental complex that consists of Fumertonian acquaintances. When we have an epistemic reason, we have a mental complex that is related in the appropriate way to a belief. This is just what provides justification for the belief. This chapter explicates this notion. It includes an extended discussion of Richard Fumerton’s theory of non-inferential justification, which I follow in outline but diverge from in detail. This discussion focuses on his notion of acquaintance, and the items with which we may be acquainted. I then move to a discussion of the metaphysics of epistemic reasons, explaining how they consist of these acquaintances. I also discuss the relationship between epistemic reasons and epistemic justification. The third chapter is historical in focus. I examine Sellars’s famous dilemma for foundationalism, and contend that it can be best understood as an attempt to deny the foundationalist epistemic reasons for his beliefs. I also examine Laurence BonJour’s later formulation of the Sellarsian dilemma, and again argue that it is best understood as denying epistemic reasons to foundationalists. I then review the options that an acquaintance foundationalist has to respond to these dilemmas, as these responses will allow us to see where our more recent dilemmas go wrong. Chapter four address Jack Lyons’s dilemma. I consider what Lyons says about his dilemma at some length. I then argue that it is structurally similar to the Sellarsian dilemma, and tries to undermine the internalist’s ability to offer epistemic reasons for his beliefs. I then argue that Lyons’s dilemma only seems persuasive because he misunderstands what is required for experience to provide us with an epistemic reason. When properly understood, his dilemma fails to tell against the acquaintance foundationalism. I also argue that Lyons’s version of externalism is much more radical than it might initially appear, helping to motivate acquaintance foundationalism. The fifth chapter focuses on Michael Bergmann. I give his dilemma an extended discussion, which I follow up by reframing it in terms of epistemic reasons. I argue that his dilemma, while seemingly persuasive, fails to trouble the acquaintance foundationalism. I argue that we may be strongly aware of our epistemic reasons without starting a regress, which vitiates his dilemma. I conclude with some short remarks on possibility of skepticism. (shrink)

Defenders of the Knowledge Argument contend that physicalism is false because knowing all the physical truths is not sufficient to know all the truths about the world. In particular, proponents of the Knowledge Argument claim that physicalism is false because the truths about the character of conscious experience are not knowable from the complete set of physical truths. This dissertation is a defense of the Knowledge Argument. Chapter one characterizes what physicalism is and provides support for the claim that if (...) knowing all the physical truths is not sufficient to know all the truths about the world, then physicalism is false. In chapter two, I defend the claim that knowing all the physical truths is not sufficient for knowing all the truths about the world. In addition to mounting a prima facie case for the knowledge intuition, I present and defend an epistemology grounded in direct acquaintance to provide a more substantive argument to accept it. Chapters three through five address the physicalist objections to the Knowledge Argument. The first set of objections advocates that knowing all the physical truths is, in fact, sufficient for knowing all the truths about the world. The next set of objections admits that there is some sense in which knowing all the physical truths is not sufficient for knowing all the truths about the world. However, these objections maintain that the kind of knowledge that is absent from the complete set of physical truths is know-how or knowledge by acquaintance, and not factual or propositional knowledge. The final set of objections maintain that the kind of propositional knowledge that is left out of the complete set of physical truths is compatible with physicalism. My response to these objections is part of advancing my prima facie case for the Knowledge Argument. The final chapter addresses a structural question that pertains to the Knowledge Argument. Some philosophers have maintained that the structure of the Knowledge Argument invites a kind of self-refutation of any systematic account of reality. The concern is that the Knowledge Argument proves too much, and that the dualist who uses the argument to refute physicalism risks the argument defeating his own position. I will argue that the Knowledge Argument does not refute dualism. (shrink)

Jackson's black-and-white Mary teaches us that the propositional content of perception cannot be fully expressed in language.

Does epistemology collapse for lack of resources other than logic, conceptual analysis and descriptions of one’s own apparent experiences, thoughts and beliefs? No, but understanding how and why not requires, Kant noted, a ‘changed method of thinking’. Some of these methodological changes are summarised in §2 in order to identify a philosophical role for thought experiments to help identify logically contingent, though cognitively fundamental capacities and circumstances necessary to human thought, experience and knowledge. As Kant also noted, experiments are only (...) informative in response to posing the right question, indeed: the right kind of question. Accordingly, preparations for these epistemological thought experiments fill half of this chapter. The second half, examines three such thought experiments, variously developed by Kant, Hegel, C. I. Lewis, Austin, Wittgenstein and F. L. Will. (shrink)

This paper argues that the notion of explicit belief in Ortega y Gasset (1946) and Wittgenstein (1969) requires a non-intellectualist understanding of certainty, what is called vital certainty. It is argued that the normative role of the hinge propositions prevents skeptic doubt and, in turn, enables epistemology. This normative role is understood as a-epistemic, even if we can affirm a sui generis use of ''I know''. Finally, skeptical reading is discussed as a possible case of loss of certainty, and how (...) vital certainty responds to these cases. (shrink)

Recent advances in our understanding of complex dynamical systems may be of interest to philosophers seeking the best metaphysical grounds for understanding the qualitative character of subjective experience (qualia). In this thesis I will propose that qualia are not specifically brain processes, but are instead best thought of as world processes that can be characterized as distributed self-organizing networks of Whiteheadian actual entities. On this Whiteheadian model, different aspects of a quale that a subject experiences as a specific shade of (...) blue, might be contributed by entities that are, contemporaneously, also contributing other aspects of other qualia to other subjects widely distributed throughout time and space. Cellular automata and network models will be used to help clarify this proposal. (shrink)
