I examine the thesis that Otto Neurath anticipated the programme of naturalised epistemology already at the time of the Vienna Circle and consider the relation between Neurath's proposals and those of two contemporary theorists whose research programmes he would thus have broadly anticipated. The thesis is confirmed by reference to Neurath's own writings. The connection between Neurath's programme and the programmes of his two successors considered here, however, is found to be highly indirect in one case and nonexistent in the (...) other — despite their undeniable overlap.

According to quasi-empiricism, mathematics is very like a branch of natural science. But if mathematics is like a branch of science, and science studies real objects, then mathematics should study real objects. Thus a quasi-empirical account of mathematics must answer the old epistemological question: How is knowledge of abstract objects possible? This paper attempts to show how it is possible.The second section examines the problem as it was posed by Benacerraf in Mathematical Truth and the next section presents a way (...) of looking at abstract objects that purports to demythologize them. In particular, it shows how we can have empirical knowledge of various abstract objects and even how we might causally interact with them. (shrink)

A minimal essentialism (‘intrinsic biological essentialism’) about natural kinds is required to explain the projectability of human science terms. Human classifications that yield robust and ampliative projectable inferences refer to biological kinds. I articulate this argument with reference to an intrinsic essentialist account of HPC kinds. This account implies that human sciences (e.g., medicine, psychiatry) that aim to formulate predictive kind categories should classify biological kinds. Issues concerning psychiatric classification and pluralism are examined.

Michael Friedman’s Dynamics of Reason is a welcome contribution to the ongoing articulation of philosophical perspectives for understanding the sciences in the context of post-positivist philosophy of science. Two perspectives that have gained advocacy since the demise of the “received view” are Quinean naturalism and Kuhnian relativism. In his 1999 Stanford lectures, Friedman articulates and defends a neo-Kantian perspective for philosophy of science that opposes both of these perspectives. His proffered neo-Kantian perspective is presented within the context of the problem (...) of theory change or “scientific revolutions,” and its main feature is a conception of scientific knowledge that requires “relativized constitutive a priori principles.” The lectures make up the first part of the book; the second part of the book, “Fruits of Discussion,” is a further elaboration and defence of the ideas advanced in the lectures. The resulting book serves as a useful sequel to Friedman’s impressive historical studies in Foundations of Space-Time Theories, Kant and the Exact Sciences, and Reconsidering Logical Positivism. In the preface, Friedman tells us that this book represents the philosophical viewpoint that he has arrived at as a result of completing these works. As such, it is not surprising that the prominent themes of the book are ones that have occupied Friedman’s attention in the past, viz., the importance of a priori principles in the exact sciences, the conventionalism of the logical positivists, and, more generally, an articulation of what remains defensible in neo-Kantian philosophy of science.

The Univalent Foundations of Mathematics provide not only an entirely non-Cantorian conception of the basic objects of mathematics but also a novel account of how foundations ought to relate to mathematical practice. In this paper, I intend to answer the question: In what way is UF a new foundation of mathematics? I will begin by connecting UF to a pragmatist reading of the structuralist thesis in the philosophy of mathematics, which I will use to define a criterion that a formal (...) system must satisfy if it is to be regarded as a “structuralist foundation.” I will then explain why both set-theoretic foundations like ZFC and category-theoretic foundations like ETCS satisfy this criterion only to a very limited extent. Then I will argue that UF is better-able to live up to the proposed criterion for a structuralist foundation than any currently available foundational proposal. First, by showing that most criteria of identity in the practice of mathematics can be formalized in terms of the preferred criterion of identity between the basic objects of UF. Second, by countering several objections that have been raised against UF’s capacity to serve as a foundation for the whole of mathematics. (shrink)

Let us begin with a fundamental realization: No amount of thinking and no amount of public policy have brought us any closer to understanding and solving the problem of crime. The more we have reacted to crime, the farther we have removed ourselves from any understanding and any reduction of the problem. In recent years, we have floundered desperately in reformulating the law, punishing the offender, and quantifying our knowledge. Yet this country remains one of the most crime-ridden nations. In (...) spite of all its wealth, economic development, and scientific advances, this country has one of the worst crime records in the world.With such realization, we return once again—as if starting anew—to the subject of crime, a subject that remains one of our most critical indicators of the state of our personal and collective being. If what is to be said seems outrageous and heretical, it is only because it is necessarily outside the conventional wisdom both of our understanding of the problem and of our attempt to solve it.

This paper seeks to uncover and rationally reconstruct four theoretical prescriptions that H. L. A. Hart urged philosophers to observe and follow when investigating and theorizing about the nature of law. The four prescriptions may appear meager and insignificant when each is seen in isolation, but together as an inter-connected set they have substantial implications. In effect, they constitute a central part of Hart’s campaign to put philosophical investigations about the nature of law onto a path to a genuine research (...) program. The paper takes note of certain prevalent and robust trends in contemporary legal philosophy that detract its practitioners from the four prescriptions, and that have them revert to the some older modes of thinking from which Hart sought a decisive break. A number of contemporary legal philosophers’ views and commitments are taken up and assessed, and in particular those of John Gardner and Leslie Green. (shrink)

The nature of the relation between jurisprudential theories and first-order legal judgments is a strangely uncontroversial matter in contemporary legal philosophy. There is one dominant conception of the relation according to which jurisprudential theories are second-order or meta-legal theories that specify the ultimate grounds of first-order legal judgments. According to this conception, difficult first-order legal disputes are to be resolved by jurisprudential theorizing. According to an alternative conception that Ronald Dworkin has influentially advocated, jurisprudential theories are not second-order theories about (...) the nature of law, but instead covert first-order legal theories. These two conceptions of the relation between jurisprudential theories and first-order legal judgments dominate the contemporary legal philosophical scene and crowd out other possible conceptions. This article scrutinizes the two conceptions, and in the process raises the possibility of a different and arguably more credible conception. According to this new conception, our first-order legal views and a jurisprudential theory that we accept are supposed to form a mutually disciplining and supporting set of views that we accept in our pursuit of the epistemic ideal of wide reflective equilibrium. The two sets of views are supposed to constrain and discipline each other; but neither is meant to underwrite, certify, or ultimately determine the contents of the other. This new conception, which allows the relation between jurisprudential theories and first-order legal judgments to be much looser, untidier, and more complex than what the two dominant conceptions imply, should facilitate progress in legal philosophy and in first-order legal thinking.

These two books are Volumes 1 and 2 of a three-volume work; the projected third volume, Warranted Christian Belief, has yet to be published. In the first volume, Warrant: The Current Debate, Plantinga surveys the current chaos in epistemology stemming from the breakdown of classical foundationalism and examines critically the efforts of several contemporary philosophers to introduce some order into the field, most particularly Roderick Chisholm, William Alston, John Pollock, Laurence BonJour and, to a lesser extent, others such as Richard (...) Foley, Fred Dretske and Alvin Goldman. In this volume, Plantinga is trying not only to put out of play the views he rejects but also to provide the reader with anticipations of his own views in Warrant and Proper Function. Although there is an immense amount of overlap between these books, and there is much cross-referencing, they are not continuous; each can be read entirely independently of the other. Even should, through some misfortune, the projected third volume fail to be written, these two volumes are certain to stand for a long time as exceptionally important works. Warrant and Proper Function, in particular, is likely to generate a veritable Niagara of Ph.D. theses in a field many had come to see as having reached the point of diminishing nits. (shrink)

As demonstrated by several example displays, color illusions challenge color realism, because they involve a one-to-many reflectance-to-color mapping. Solving this problem by differentiating between veridical and illusory colors corresponding to the same reflectance is hampered because of the lack of an appropriate criterion. However, the difference between veridical and illusory color perception can still be maintained.

The Churchlands are notorious for their theory of eliminative materialism (EM). This theory has become associated with scientism and a possible death of philosophy. In this article, I will closely examine the most common accusations made against EM and try to give an overall assessment of them. The conclusion is that EM survives most of the criticisms levelled against it. For sure, there are many things to do to improve on the current form of the theory, but none of them (...) seems to be unsurpassable. The charges of blind enthusiasm, reductionism, neuroscience exceptionalism and scientism originate from widespread misconceptions about the nature of actual science. Furthermore, the objection that EM is self-defeating is answered. (shrink)

The Sleeping Beauty Problem attracts so much attention because it connects to a wide variety of unresolved issues in formal epistemology, decision theory, and the philosophy of science. The problem raises unanswered questions concerning relative frequencies, objective chances, the relation between self-locating and non-self-locating information, the relation between self-location and updating, Dutch Books, accuracy arguments, memory loss, indifference principles, the existence of multiple universes, and many-worlds interpretations of quantum mechanics. After stating the problem, this article surveys its connections to all (...) of these areas. (shrink)

This paper contains an overview of the essays contained in the Mind and morals anthology plus a critical discussion of certain themes raised in many of these essays concerning the bearing of recent work in cognitive science on the traditional project of moral theory. Specifically, I argue for the following claims: (1) authors like Virginia Held, who appear to be antagonistic toward the methodological naturalism of Owen Flanagan, Andy Clark, Paul Churchland, and others, are really in fundamental agreement with the (...) naturalists (at least once the naturalist view is suitably clarified); (2) the prototype theory of moral concepts that is inspired by recent work in cognitive science does not necessarily jeopardize the aim of systematization characteristic of traditional moral theory; (3) nor does it threaten certain widely accepted views about moral rationality that is part of traditional moral theorizing. Moreover, I speculate that (4) recent work in cognitive science can be expected to play a corroborative role in the justification of theories in ethics, but we should probably not expect this work to yield new insights and directions in ethics. Finally, (5) Fodor's recent critique of cognitive science makes clear the perils of methodological ethical naturalism. (shrink)

Kantian constructivists locate the source of normativity in the rational nature of valuing agents. Some further argue that accepting this premise thereby commits one to accepting the intrinsic or unconditioned value of rational nature itself. Whereas much of the critical literature on this “regress on conditions” argument has focused either on the cogency of the inference from the value-conferring capacity of the will to the unconditional value of that capacity itself or on the plausibility of the initial constructivist premise, my (...) aim is to press the argument from a different direction by asking just how Kantian the constructivist needs to be in order to support a regress on conditions argument. Specifically, I maintain that the argument succeeds only given a full-fledged Kantian moral psychology, including a presupposition of transcendental freedom. If correct, this could have implications regarding the compatibility of Kantian ethics and philosophic naturalism. (shrink)

Quine and others have recommended principles of charity which discourage judgments of irrationality. Such principles have been proposed to govern translation, psychology, and economics. After comparing principles of charity of different degrees of severity, we argue that the stronger principles are likely to block understanding of human behavior and impede progress toward improving it. We support a moderate principle of charity which leaves room for empirically justified judgments of irrationality.

Social individuals are social entities having a distinctive individuality, often signaled by the use of a proper name to designate them. This article proposes an account of social individuals based on the notion of a mental file, understood as a repository of information about a single individual. First, I consider a variant of the puzzle of the ship of Theseus in which the object having problematic identity conditions is a social individual, namely, a rock band. Then, I argue that we (...) can figure out such identity conditions by considering the mental files concerning this band. In conclusion, I outline a version of social constructionism according to which the existence of social individuals like bands depends on mental files about them. (shrink)

Facts about moral disagreement and human evolution have both been said to exclude the possibility of moral knowledge, but the question of how these challenges interact has largely gone unaddressed. The paper aims to present and defend a novel version of the evolutionary “debunking” argument for moral skepticism that appeals to both types of considerations. This argument has several advantages compared to more familiar versions. The standard debunking strategy is to argue that evolutionary accounts of moral beliefs generate skeptical implications (...) because they attribute those beliefs to factors that are unrelated to their truth. That strategy is vulnerable to “third-factor” responses, which invoke first-order moral claims to challenge the assumption that Darwinian factors and the moral truths are really unrelated in that way. In contrast, our version is immune to those responses, as it does not proceed via assumptions about how Darwinian factors relate to the moral facts. Instead, it focuses on what evolutionary accounts of moral beliefs have to say about the fact that people often reach divergent moral beliefs. The argument thereby illustrates how the debunking strategy can join forces with the argument from moral disagreement. The combination of those strategies presents, we think, a challenge that is more formidable than when they are considered separately. (shrink)

After identifying the discipline of psychology’s history of contributing pioneers and leaders to the field of race research, epistemological problems in empirical psychology are identified including an adherence to a naïve empiricist philosophy of science. The reconstruction focuses on the underdetermined relationship between data and interpretation. It is argued that empirical psychology works under a hermeneutic deficit and that this deficit leads to the advancement of interpretations regarding racialized groups that are detrimental to those groups. Because these interpretations are understood (...) as actions that bring harm to certain racialized groups, and because these actions are made in the name of science and knowledge, the term epistemological violence is applied. Reflections regarding the meanings and consequences of this term in empirical psychology and the human sciences are presented. (shrink)

Shepard has argued that a universal law should govern generalization across different domains of perception and cognition, as well as across organisms from different species or even different planets. Starting with some basic assumptions about natural kinds, he derived an exponential decay function as the form of the universal generalization gradient, which accords strikingly well with a wide range of empirical data. However, his original formulation applied only to the ideal case of generalization from a single encountered stimulus to a (...) single novel stimulus, and for stimuli that can be represented as points in a continuous metric psychological space. Here we recast Shepard's theory in a more general Bayesian framework and show how this naturally extends his approach to the more realistic situation of generalizing from multiple consequential stimuli with arbitrary representational structure. Our framework also subsumes a version of Tversky's set-theoretic model of similarity, which is conventionally thought of as the primary alternative to Shepard's continuous metric space model of similarity and generalization. This unification allows us not only to draw deep parallels between the set-theoretic and spatial approaches, but also to significantly advance the explanatory power of set-theoretic models. Key Words: additive clustering; Bayesian inference; categorization; concept learning; contrast model; features; generalization; psychological space; similarity. (shrink)

Quine's essay, “Ontological Relativity” [2] has brought about not a little confusion and disagreement. What is Quine's doctrine, and what are his arguments for it? The following paragraphs search for an answer. First a word about my aims. I will avoid adding to the already extensive discussion of Quine's older thesis of the indeterminacy of translation. Instead, where connections between the old and new doctrines become apparent, I will focus on the connections themselves and their repercussions for ontological relativity.

Vision scientists are interested in three diverse entities: physical stimuli, neural states, and consciously perceived colors, and in the mapping rules among the three. In this worldview, the three kinds of entities have coequal status, and views that attribute color exclusively to one or another of them, such as color realism, have no appeal.

The main thesis of this paper is that it is not possible to determine the nature of epistemic justification apart from scientific psychological investigation. I call this view the strong thesis of methodological psychologism. Two sub-theses provide the primary support for this claim. The first sub-thesis is that no account of epistemic justification is correct which requires for the possession of at least one justified belief a psychological capacity which humans do not have. That is, the correct account of epistemic (...) justification must be psychologically realistic. The second sub-thesis is that it is not possible to determine whether an account of epistemic justification is psychologically realistic apart from scientific psychological investigation. After defending these subtheses, I point out some interesting consequences of the overall thesis which present a challenge to traditional epistemology. (shrink)

In this paper, I explore how bio-hybrid forms can be created and combined starting from organic forms. The thesis put forward is epistemological: the combinatorial practice of bionics, biomimetics, biorobotics, and all design strategies inspired by nature is not based on a kind of biomimetic inspiration, i. e., on a kind of imitation of nature, but on a practice of translation. To develop this thesis, I focus on the practices of contemporary biorobotics, first examining the practice of translating natural forms (...) into technical artefacts as developed by Raoul Heinrich Francé at the beginning of the 20th century, secondly, analysing the production of robots capable of replicating complex locomotion systems and, finally, investigating the interaction between robots and living organisms (fish). In the last part of the paper, I reflect on the philosophical payoff and broader conditions of possibility for this translational practice. I discuss when and to what extent a translation of biological forms into biotechnical ones is acceptable and point out the notion of form that underlies this practice. Moreover, I draw attention to the need to philosophically investigate what happens between different domains of knowledge – and especially between science and technology. This article is thus an invitation to philosophers to develop a philosophy in the interstices of knowledge production. (shrink)

The article distinguishes between subjectivist and objectivist interpretations of scientific method, links subjectivism with good reasons, and argues its uselessness for our understanding of science. It applies the distinction to the method of falsification, explains why objectivism regards falsification to be conjectural, immune to the Duhem–Quine thesis, and immune to the problem of underdetermination. It confronts the falsifying mode of inference with the fallacy of begging the question and with the paradox of inference, and suggests how modus tollens helps scientists (...) to find out that a tested theory is false, in spite of the fact that the falsity of the theory is asserted in its premises.

Davidson develops an argument that establishes the most basic set-up for rationality. The minimal set-up is a triangle formed by two subjects and an object. Each of the two subjects occupies one of the three angles and the third angle is occupied by a subject matter – that about which the two subjects are in communication with one another. I extend Davidson's argument somewhat and show how an entire pluralistic community is required for individuals to develop most fully as rational (...) creatures. I do this by showing how the basic conditions for rationality set out by Davidson would start to crumble in conditions such as those set out in Orwell's Nine teen Eighty-Four. The ideal, as opposed to the minimal, set-up for rationality is not a triangle, but a pluralistic network of subjects. And indeed, the ideal conditions for rationality are to a large extent just that because they allow for the full implementation of Davidson's minimal set-up. S. Afr. J. Philos. Vol.23(1) 2004: 54–68.

I will argue that the ontological doctrine of physicalism inevitably entails the denial that there is anything conceptual in logic and mathematics. The elements of a formal system, even if they are tagged by suggestive names, are merely meaningless parts of a physically existing machinery, which have nothing to do with concepts, because they have nothing to do with the actual things. The only situation in which they can become meaning-carriers is when they are involved in a physical theory. But (...) in this role they refer to elements of the physical reality, i.e. they represent a physical concept. “Mathematical concepts” are just idols, that philosophy can completely deny and physics can completely ignore.

According to a view I’ll call Epistemic Normativism, knowledge is normative in the same sense in which paradigmatically normative properties like justification are normative. This paper argues against EN in two stages and defends a positive non-normativist alternative. After clarifying the target in §1, I consider in §2 some arguments for EN from the premise that knowledge entails justification. I first raise some worries about inferring constitution from entailment. I then rehearse the reasons why some epistemologists reject the Entailment Thesis (...) and argue that a non-normativist picture provides the best explanation of all the intuitions surrounding this thesis, favorable and unfavorable. On this picture, human knowledge is a structured non-normative complex that has as one of its parts a justification-making property, analogous in role to good-making properties like pleasurableness. After giving three arguments against EN in §3 and answering an objection in §4, I turn in §5 to further develop the positive view sketched in §2. In §6, I take stock and conclude. (shrink)

It is argued that a number of important, and seemingly disparate, types of representation are species of a single relation, here called structural representation, that can be described in detail and studied in a way that is of considerable philosophical interest. A structural representation depends on the existence of a common structure between a representation and that which it represents, and it is important because it allows us to reason directly about the representation in order to draw conclusions about the (...) phenomenon that it depicts. The present goal is to give a general and precise account of structural representation, then to use that account to illuminate several problems of current philosophical interest — including some that do not initially seem to involve representation at all. In particular, it is argued that ontological reductions (like that of the natural numbers to sets), compositional accounts of semantics, several important sorts of mental representation, and (perhaps) possible worlds semantics for intensional logics are all species of structural representation and are fruitfully studied in the framework developed here.

On a widespread reading, the Carnap-Quine debate about ontology concerns the objectivity and non-triviality of ontological claims. I argue that this view mischaracterizes Carnap’s aims in “Empiricism, Semantics, and Ontology” : Carnap’s fundamental goal is to free up decisions about scientific language from constraints deriving from ontological doctrine. The contention, based on his internal/external distinction, that ontological claims are either meaningless or trivial was Carnap’s means to achieving this more fundamental goal. Setting the record straight on this point brings out (...) three important and often overlooked features of Carnap’s views on ontology. First, the target of Carnap’s critique in ESO is not Quine’s mature views on ontology, as laid out in “On What There Is”. Rather, Carnap is responding to arguments for nominalism that were given by Tarski, Goodman, and Quine in the 1940s. Second, a more general rejection of conservatism in theory choice is essential to Carnap’s aims and is implicit in his fundamental views on language. Third, even if it turns out to be tenable, the i/e distinction is not adequate for Carnap’s aim in ESO. Drawing on his basic conception of scientific language, I will suggest an alternative approach on his behalf. (shrink)

This paper aims to offer a new argument in defence bacterial species pluralism. To do so, I shall first present the particular issues derived from the conflict between the non-theoretical understanding of species as units of classification and the theoretical comprehension of them as units of evolution. Secondly, I shall justify the necessity of the concept of species for the bacterial world, and show how medicine and endosymbiotic evolutionary theory make use of different concepts of bacterial species due to their (...) distinctive purposes. Finally, I shall show how my argument provides a new source of defence for bacterial pluralism. (shrink)

In the present paper I wish to regard constructivelogic as a self-contained system for the treatment ofepistemological issues; the explanations of theconstructivist logical notions are cast in anepistemological mold already from the outset. Thediscussion offered here intends to make explicit thisimplicit epistemic character of constructivism.Particular attention will be given to the intendedinterpretation laid down by Heyting. This interpretation, especially as refined in the type-theoretical work of Per Martin-Löf, puts thesystem on par with the early efforts of Frege andWhitehead-Russell.

Naturalists seek to ground what exists in a set of fundamental metaphysical principles that they call ‘nature’. But metaphysical principles can’t function as fundamental explanatory grounds, since their ability to explain anything depends on the intelligibility granted by transcendental structures. What makes metaphysical principles intelligible, what unifies them, and allows them to characterize the being of worldly objects are the transcendental structures through which worldly objects are manifest. This means that the search for fundamental explanatory grounds must go deeper than (...) the postulation of brute metaphysical facts. But this search cannot end with transcendental structures either, since the mode of being of transcendental subjects also calls out for explanation. Conceiving of transcendental subjects through the concept of being-in-the-world ties the mode of being of subjects to the world they inhabit. What grounds the existence of worldly objects, and what grounds our existence as being-in-the-world is nature: a principle that is neither an object, nor a subject – a principle that makes possible our encounters with intelligible worldly things.

Paul Thagard has recently argued that thought experiments are dangerous and misleading when we try to use them as evidence for claims. This paper refutes his skepticism. Building on Thagard’s own work in cognitive science, I suggest that Thagard has much that is positive to say about how thought experiments work. My last section presents some new directions for research on the intersection between thought experiments and cognitive science.

In recent years there has been a great deal of discussion about the prospects of developing a “naturalized epistemology,” though different authors tend to interpret this label in quite different ways.1 One goal of this paper is to sketch three projects that might lay claim to the “naturalized epistemology” label, and to argue that they are not all equally attractive. Indeed, I’ll maintain that the first of the three – the one I’ll attribute to Quine – is simply incoherent. There (...) is no way we could get what we want from an epistemological theory by pursuing the project Quine proposes. The second project on my list is a naturalized version of reliabilism. This project is not fatally flawed in the way that Quine’s is. However, it’s my contention that the sort of theory this project would yield is much less interesting than might at first be thought.

Can scientific evidence prompt us to revise philosophical theories or folk theoretical accounts of phenomena of the mind? We will argue that it can—but only under the condition that they make a so-called ‘ontological commitment’ to something that is actually subject to empirical inquiry. In other words, scientific evidence pertaining to neuroanatomical structure or causal processes only has a refuting effect if philosophical theories and folk notions subscribe to either account. We will illustrate the importance of ‘ontological commitment’ with the (...) ‘neuroanatomical approach’ to amusement as proposed in a recent paper by Palencik :419–434, 2007). We will show that the scientific evidence presented in said neuroanatomical approach has no bearing on the conceptual issues, in that the philosophical theories and folk distinction that are criticized do not subscribe to any account of the underlying neuroanatomical structure or causal processes. Our suggestions in this paper are not limited to philosophical accounts of humor but apply to the relationship of philosophy, common sense and science in general. (shrink)
