Reformed epistemology and cognitive science have remarkably converged on belief in God. Reformed epistemology holds that belief in God is basic—that is, belief in God is a natural, non-inferential belief that is immediately produced by a cognitive faculty. Cognitive science of religion also holds that belief in gods is (often) non-reflectively and instinctively produced—that is, non-inferentially and automatically produced by a cognitive faculty or system. But there are differences. In this paper, we will show some remarkable points of convergence, and (...) a few points of divergence, between Reformed epistemology and the cognitive science of religion. (shrink)
We report the results of a cross-cultural investigation of person-body reasoning in the United Kingdom and northern Brazilian Amazon (Marajó Island). The study provides evidence that directly bears upon divergent theoretical claims in cognitive psychology and anthropology, respectively, on the cognitive origins and cross-cultural incidence of mind-body dualism. In a novel reasoning task, we found that participants across the two sample populations parsed a wide range of capacities similarly in terms of the capacities’ perceived anchoring to bodily function. Patterns of (...) reasoning concerning the respective roles of physical and biological properties in sustaining various capacities did vary between sample populations, however. Further, the data challenge prior ad-hoc categorizations in the empirical literature on the developmental origins of and cognitive constraints on psycho-physical reasoning (e.g., in afterlife concepts). We suggest cross-culturally validated categories of “Body Dependent” and “Body Independent” items for future developmental and cross-cultural research in this emerging area. (shrink)
In sketching a preliminary scientific theory of religion, Atran & Norenzayan (A&N) generally agree with cognitive scientists of religion in the factors that coalesce to form religion. At times they misrepresent, however, the notion of “counterintuitive” concepts as they apply to religious concepts, confusing counterintuitive with counterfactual, category mistakes, and logical contradiction.

Widely recognized as the finest definition of existentialist Philosophy, this book introduced existentialism to America in 1958. Barrett discusses the views of 19th and 20th century existentialists Kierkegaard, Nietzsche, Heidegger, and Sartre and interprets the impact of their thinking on literature, art, and philosophy.
A many-worlds interpretation is of quantum mechanics tells us that the linear equations of motion are the true and complete laws for the time-evolution of every physical system and that the usual quantum-mechanical states provide complete descriptions of all possible physical situations. Such an interpretation, however, denies the standard way of understanding quantum-mechanical states. When the pointer on a measuring device is in a superposition of pointing many different directions, for example, we are to understand this as many pointers, each (...) in a differentworld, each pointing in a different determinate direction. We ask here whether such talk makes any genuinely intelligible sense of the term world. We conclude that it does not. (shrink)

In the literature on multiple realizability and the identity theory, cases of neural plasticity have enjoyed a very limited role. The present article attempts to remedy this small influence by arguing that clinical and experimental evidence of quite extensive neural reorganization offers compelling support for the claim that psychological kinds are multiply realized in neurological kinds, thus undermining the identity theory. In particular, cases are presented where subjects with no measurable psychological deficits also have vast, though gradually received, neurological damage. (...)

Modularity has been the subject of intense debate in the cognitive sciences for more than 2 decades. In some cases, misunderstandings have impeded conceptual progress. Here the authors identify arguments about modularity that either have been abandoned or were never held by proponents of modular views of the mind. The authors review arguments that purport to undermine modularity, with particular attention on cognitive architecture, development, genetics, and evolution. The authors propose that modularity, cleanly defined, provides a useful framework for directing (...) research and resolving debates about individual cognitive systems and the nature of human evolved cognition. Modularity is a fundamental property of living things at every level of organization; it might prove indispensable for understanding the structure of the mind as well. (shrink)

I argue that a strong mind–body dualism is required of any formulation of quantum mechanics that satisfies a relatively weak set of explanatory constraints. Dropping one or more of these constraints may allow one to avoid the commitment to a mind–body dualism but may also require a commitment to a physical–physical dualism that is at least as objectionable. Ultimately, it is the preferred basis problem that pushes both collapse and no-collapse theories in the direction of a strong dualism in resolving (...) the quantum measurement problem. Addressing this problem illustrates how the construction and evaluation of explanatorily rich physical theories are inextricably tied to the evaluation of traditional philosophical issues. (shrink)
W. V. O. Quine's well-known attack upon the analytic-synthetic distinction is held to affect only one of the two species of analytic statements he distinguishes. In particular it is not directed at and does not affect the so-called logical truths. In this paper the scope of Quine's attack is extended so as to embrace the logical truths as well. It is shown that the unclarifiability of the notion of 'synonymy' deprives us not only of "analytic statements that are obtainable from (...) logical truths by the replacement of synonyms with synonyms" but of "logical truths" themselves.

It has been argued that nonreductive physicalism leads to epiphenominalism about mental properties: the view that mental events cannot cause behavioral effects by virtue of their mental properties. Recently, attempts have been made to develop accounts of causal relevance for irreducible properties to show that mental properties need not be epiphenomenal. In this paper, I primarily discuss the account of Frank Jackson and Philip Pettit. I show how it can be developed to meet several obvious objections and to capture our (...) intuitive conception of degrees of causal relevance. However, I argue that the account requires large-scale miraculous coincidence for there to be causally relevant mental properties. I also argue that the same problem arises for two apparently very different accounts of causal relevance. I suggest that this result does not show that these accounts, on appropriate readings, are false. Therefore, I tentatively conclude that we have reason to believe that irreducible mental properties are causally irrelevant. Moreover, given that there is at leastprima facie evidence that mental properties can be causally relevant, my conclusion casts doubt on nonreductive physicalist theories of mental properties.

This essay examines the proposal that psychological essentialism results from a history of natural selection acting on human representation and inference systems. It has been argued that the features that distinguish essentialist representational systems are especially well suited for representing natural kinds. If the evolved function of essentialism is to exploit the rich inductive potential of such kinds, then it must be subserved by cognitive mechanisms that carry out at least three distinct functions: identifying these kinds in the environment, constructing (...) essentialized representations of them, and constraining inductive inferences about kinds. Moreover, there are different kinds of kinds, ranging from nonliving substances to biological taxa to within-species kinds such as sex, and the causal processes that render these categories coherent for the purposes of inductive generalization vary. If the evolved function of essentialism is to support inductive generalization under ignorance of true causes, and if kinds of kinds vary in the implicit assumptions that support valid inductive inferences about them, then we expect different, functionally incompatible modes of essentialist thinking for different kinds. In particular, there should be differences in how biological and nonbiological substances, biological taxa, and biological and social role kinds are essentialized. The functional differences between these kinds of essentialism are discussed. (shrink)
Given Hugh Everett III's understanding of the proper cognitive status of physical theories, his relative-state formulation of pure wave mechanics arguably qualifies as an empirically acceptable physical theory. The argument turns on the precise nature of the relationship that Everett requires between the empirical substructure of an empirically faithful physical theory and experience. On this view, Everett provides a weak resolution to both the determinate record and the probability problems encountered by pure wave mechanics, and does so in a way (...) that avoids unnecessary metaphysical complications. Taking Everett's goal to be showing the empirical faithfulness of the relative-state formulation agrees well with his characterization of his project as one of seeking a model for observation in the correlation structure described by pure wave mechanics and seeking a measure of typicality over this empirical substructure that covaries with our empirically warranted expectations.

William Alston’s Theory of Appearing has attracted considerable attention in recent years, both for its elegant interpretation of direct realism in light of the presentational character of perceptual experience and for its central role in his defense of the justificatory force of Christian mystical experiences. There are different ways to account for presentational character, however, and in this article we argue that a superior interpretation of direct realism can be given by a theory of perception as dynamic engagement. The conditions (...) for dynamic engagement are such that there can be no absolute discontinuity between individual perceptual experiences and more public forms of inquiry, and this requirement has radical consequences for the prima facie justificatory force of religious experience.

David Buller’s recent book, _Adapting Minds_, is a philosophical critique of the field of evolutionary psychology. Buller argues that evolutionary psychology is utterly bankrupt from both a theoretical and an empirical point of view. Although _Adapting Minds _has been well received in both the academic press and the popular media, we argue that Buller’s critique of evolutionary psychology fails.
There is good reason to suppose that our best physical theories are false: In addition to its own internal problems, the standard formulation of quantum mechanics is logically incompatible with special relativity. I will also argue that we have no concrete idea what it means to claim that these theories are approximately true.
Skyrms–Lewis signaling games illustrate how meaningful language may evolve from initially meaningless random signals (Lewis, Convention 1969 ; Skyrms 2008 ). Here we will consider how incommensurable languages might evolve in the context of signaling games. We will also consider the types of incommensurability exhibited between evolved languages in such games. We will find that sequentially evolved languages may be strongly incommensurable while still allowing for increasingly faithful descriptions of the world.
Context: There is a growing recognition in consciousness science of the need for rigorous methods for obtaining accurate and detailed phenomenological reports of lived experience, i.e., descriptions of experience provided by the subject living them in the “first-person.” Problem: At the moment although introspection and debriefing interviews are sometimes used to guide the design of scientific studies of the mind, explicit description and evaluation of these methods and their results rarely appear in formal scientific discourse. Method: The recent publication of (...) an edited book of papers dedicated to the exploration of first-and second-person methods, Ten Years of Viewing from Within: The Legacy of Francisco Varela, serves as a starting point for a discussion of how these methods could be integrated into the growing discipline of consciousness science. We complement a brief review of the book with a critical analysis of the major pilot studies in Varela’s neurophenomenology, a research program that was explicitly devised to integrate disciplined experiential methods with the latest advances in neuroscience. Results: The book is a valuable resource for those who are interested in impressive recent advances in first- and second-person methods, as applied to the phenomenology of lived experience. However, our review of the neurophenomenology literature concludes that there is as yet no convincing example of these specialized techniques being used in combination with standard behavioral and neuroscientific approaches in consciousness science to produce results that could not have also been achieved by simpler methods of introspective reporting. Implications: The end of behaviorism and the acceptance of verbal reports of conscious experience have already enabled the beginning of a science of consciousness. It can only be of benefit if new first- and second-person methods become well-known across disciplines. Constructivist content: Constructivism has long been interested in the role of the observer in the constitution of our sense of reality, so these developments in the science of consciousness may open new avenues of constructivist research. More specifically, one of the ways in which the insights from first- and second-person methods are being validated is by recursively applying the methods to themselves; a practical application of an epistemological move that will be familiar to constructivists from the second-order cybernetics tradition.

argued that there are two options for what he called a realistic solution to the quantum measurement problem: (1) select a preferred set of observables for which definite values are assumed to exist, or (2) attempt to assign definite values to all observables simultaneously (1810–1). While conventional wisdom has it that the second option is ruled out by the Kochen-Specker theorem, Vink nevertheless advocated it. Making every physical quantity determinate in quantum mechanics carries with it significant conceptual costs, but it (...) also provides a way of addressing the preferred basis problem that arises if one chooses to pursue the first option.

Currently, there is widespread skepticism that higher cognitive processes, given their apparent flexibility and globality, could be carried out by specialized computational devices, or modules. This skepticism is largely due to Fodor’s influential definition of modularity. From the rather flexible catalogue of possible modular features that Fodor originally proposed has emerged a widely held notion of modules as rigid, informationally encapsulated devices that accept highly local inputs and whose opera- tions are insensitive to context. It is a mistake, however, to (...) equate such features with computational devices in general and therefore to assume, as Fodor does, that higher cognitive processes must be non-computational. Of the many possible non-Fodorean architectures, one is explored here that offers possible solutions to computational problems faced by conventional modular systems: an ‘enzymatic’ architecture. Enzymes are computational devices that use lock-and-key template matching to iden- tify relevant information (substrates), which is then operated upon and returned to a common pool for possible processing by other devices. Highly specialized enzymes can operate together in a common pool of information that is not pre-sorted by information type. Moreover, enzymes can use molecular ‘tags’ to regulate the operations of other devices and to change how particular substrates are construed and operated upon, allowing for highly interactive, context-specific processing. This model shows how specialized, modular processing can occur in an open system, and suggests that skepti- cism about modularity may largely be due to failure to consider alternatives to the standard model.

There is a long tradition of trying to find a satisfactory interpretation of Everett's relative-state formulation of quantum mechanics. Albert and Loewer recently described two new ways of reading Everett: one we will call the single-mind theory and the other the many-minds theory. I will briefly describe these theories and present some of their merits and problems. Since both are no-collapse theories, a significant merit is that they can take advantage of certain properties of the linear dynamics, which Everett (...) apparently considered to be important, to constrain their statistical laws.

This study examined the influence of corporate giving programs on the link between certain categories of corporate crime and corporate reputation. Specifically, firms that violate EPA and OSHA regulations should, to some extent, experience a decline in their reputations, while firms that contribute to charitable causes should see their reputations enhanced. The results of this study support both of these contentions. Further, the results suggest that corporate giving significantly moderates the link between the number of EPA and OSHA violations committed (...) by a firm and its reputation. Thus, while a firm's reputation can be diminished through its violation of various government regulations, the extent of the decline in reputation may be significantly reduced through charitable giving.

In this paper I describe the history of the surreal trajectories problem and argue that in fact it is not a problem for Bohm's theory. More specifically, I argue that one can take the particle trajectories predicted by Bohm's theory to be the actual trajectories that particles follow and that there is no reason to suppose that good particle detectors are somehow fooled in the context of the surreal trajectories experiments. Rather than showing that Bohm's theory predicts the wrong particle (...) trajectories or that it somehow prevents one from making reliable measurements, such experiments ultimately reveal the special role played by position and the fundamental incompatibility between Bohm's theory and relativity. They also provide a striking example of the theory-ladenness of observation. (shrink)

In their 2010 book, Biology’s First Law, D. McShea and R. Brandon present a principle that they call ‘‘ZFEL,’’ the zero force evolutionary law. ZFEL says (roughly) that when there are no evolutionary forces acting on a population, the population’s complexity (i.e., how diverse its member organisms are) will increase. Here we develop criticisms of ZFEL and describe a different law of evolution; it says that diversity and complexity do not change when there are no evolutionary causes.
Out of a concern to respect the naturalistic fallacy, Ruse (1986) argues for the possibility of causal, but not justificatory, explanations of morality in terms of evolutionary processes. In a discussion of Ruse's work, Rottschaefer and Martinsen (1990) claim that he erroneously limits the explanatory scope of evolutionary concepts, because he fails to see that one can have objective moral properties without committing either of two forms of the naturalistic fallacy, if one holds that moral properties supervene on non-moral properties. (...) In this short paper I argue that Rottschaefer and Martinsen's solution fails. If one takes moral properties to supervene on non-moral properties, then either one ends up committing one of the two forms of the naturalistic fallacy or else one is left postulating unbelievable brute metaphysical facts.

Everett proposed resolving the quantum measurement problem by dropping the nonlinear collapse dynamics from quantum mechanics and taking what is left as a complete physical theory. If one takes such a proposal seriously, then the question becomes how much of the predictive and explanatory power of the standard theory can one recover without the collapse postulate and without adding anything else. Quantum mechanics without the collapse postulate has several suggestive properties, which we will consider in some detail. While these properties (...) are not enough to make it acceptable given the usual standards for a satisfactory physical theory, one might want to exploit these properties to cook up a satisfactory no-collapse formulation of quantum mechanics. In considering how this might work, we will see why any no-collapse theory must generally fail to satisfy at least one of two plausible-sounding conditions. (shrink)
Everett's relative-state formulation of quantum mechanics is an attempt to solve the measurement problem by dropping the collapse dynamics from the standard von Neumann-Dirac theory of quantum mechanics. The main problem with Everett's theory is that it is not at all clear how it is supposed to work. In particular, while it is clear that he wanted to explain why we get determinate measurement results in the context of his theory, it is unclear how he intended to do this. There (...) have been many attempts to reconstruct Everett's no-collapse theory in order to account for the apparent determinateness of measurement outcomes. These attempts have led to such formulations of quantum mechanics as the many-worlds, many-minds, many-histories, and relative-fact theories. Each of these captures part of what Everett claimed for his theory, but each also encounters problems. (shrink)

Human beings are peculiar. In laboratory experiments, they often cooperate in one-shot prisoners’ dilemmas, they frequently offer 1/2 and reject low offers in the ultimatum game, and they often bid 1/2 in the game of divide-the-cake All these behaviors are puzzling from the point of view of game theory. The first two are irrational, if utility is measured in a certain way.1 The last isn’t positively irrational, but it is no more rational than other possible actions, since there are infinitely (...) many other Nash equilibria besides the one in which both players bid 1/2. At the same time, these behaviors seem to indicate that people are sometimes inclined to be cooperative, fair, and just. In his stimulating new book, Brian Skyrms sets himself the task of showing why these inclinations evolved, or how they might have evolved, under the pressure of natural selection. The goal is not to justify our ethical intuitions, but to explain why we have them.2.. (shrink)
A resolution of the quantum measurement problem would require one to explain how it is that we end up with determinate records at the end of our measurements. Metaphysical commitments typically do real work in such an explanation. Indeed, one should not be satisfied with one's metaphysical commitments unless one can provide some account of determinate measurement records. I will explain some of the problems in getting determinate records in relativistic quantum field theory and pay particular attention to the relationship (...) between the measurement problem and a generalized version of Malament's theorem.

This paper posits that organizational variables are the factors that lead to the moral decline of companies like Enron and Worldcom. The individuals involved created environments within the organizations that precipitated a spiral of unethical decision-making. It is proposed that at the executive level, it is the organizational factors associated with power and decision-making that have the critical influence on moral and ethical behavior. The study has used variables that were deemed to be surrogate measures of the ethical violations (OSHA (...) and EPA violations), the risky shift phenomenon (executive team size), banality of wrong-doing (reputation score for firms) and escalating commitment (tenure with the firm/change in revenue for declining firms). The research found that there were small correlations between ethical violations and the three organizational variables. (shrink)
The idea that the changing entropy of a system is relevant to explaining why we know more about the system's past than about its future has been criticized on several fronts.

Abstract Robert Solomon, a philosopher noted for arguing the conciliation of reason and emotion, holds that emotions which are a lapse from rationality are unimportant. Their importance is supported here. Emotional habits of discourse, as well as of action, are discussed, unlike in most treatments of reason and emotion. The implication for cognitive and moral education is that the ability to engage in rational discussion, and the discipline to maintain application to difficult tasks, are seen as potentially curtailed by emotional (...) habits of evasion. Comments are added to contest the decisiveness of the main argument used to reconcile reason and emotion, that is, the analysis of emotions as having a cognitive element. (shrink)

A field-theoretic version of Wigner’s friend (1961) illustrates how the quantum measurement problem arises for field theory. Similarly, considering spacelike separate measurements of entangled fields by observers akin to Wigner’s friend shows the sense in which relativistic constraints make the measurement problem particularly difficult to resolve in the context of a relativistic field theory. We will consider proposals by Wigner (1961), Bloch (1967), Helwig and Kraus (1970), and Bell (1984) for resolving the measurement problem for quantum field theory. We will (...) conclude by considering the possibility of giving up rich dynamical explanation in the context of a many-maps formulation of relativistic quantum field theory. (shrink)
There are important ethical issues that must be carefully thought through when undertaking research with children. This paper explores how the context of such issues changes with the individual circumstances of the children involved, particularly when they are marginalised or excluded by wider society. By reflecting on experiences of research with Kampala street children, this paper highlights how participation throughout the research process can both raise and resolve ethical dilemmas. This is illustrated by reflecting on two examples, namely discussing sensitive (...) topics and the dissemination of socio-spatial research findings. In conclusion, the paper demonstrates the importance of ethical sensitivity to the changing situations that arise when conducting research with street children and the importance of incorporating and involving them in both the research process and ethical dilemmas.

This paper is concerned with the possibility and nature of relativistic hidden-variable formulations of quantum mechanics. Both ad hoc teleological constructions of spacetime maps and frame-dependent constructions of spacetime maps are considered. While frame-dependent constructions are clearly preferable, they provide neither mechanical nor causal explanations for local quantum events. Rather, the hiddenvariable dynamics used in such constructions is just a rule that helps to characterize the set of all possible spacetime maps. But while having neither mechanical nor causal explanations of (...) the values of quantummechanical measurement records is a significant cost, it may simply prove too much to ask for such explanations in relativistic quantum mechanics.

In this paper, I make a case for interpreting the Lysis as a dialogue of definition, designed to answer the question of “What is a friend?” The main innovation of my interpretation is the contention – and this is argued for in the paper – that Socrates hints towards a definition of being a friend that applies equally to mutual friendship and one-way attraction – the two kinds of friend relation very clearly identified by Socrates in the dialogue. The key (...) to understanding how the two different kinds of friendship can have a common definition is to appreciate that the property of being a friend has a relational character. (shrink)
Lewis sender‐receiver games illustrate how a meaningful term language might evolve from initially meaningless random signals (Lewis 1969; Skyrms 2006). Here we consider how a meaningful language with a primitive grammar might evolve in a somewhat more subtle sort of game. The evolution of such a language involves the co‐evolution of partitions of the physical world into what may seem, at least from the perspective of someone using the language, to correspond to canonical natural kinds. While the evolved language may (...) allow for the sort of precise representation that is required for successful coordinated action and prediction, the apparent natural kinds reflected in its structure may be purely conventional. This has both positive and negative implications for the limits of naturalized metaphysics. (shrink)
Jerry Fodor has defended the claim that psychological theories should appeal to narrow rather than wide intentional properties. One of his arguments relies upon the cross contexts test, a test that purports to determine whether two events have the same causally relevant properties. Critics have charged that this test is too weak, since it counts certain genuinely explanatory relational properties in science as being causally irrelevant. Further, it has been claimed, the test is insensitive to the (...) fact that special scientific laws allow for exceptions which do not undermine those laws. This paper refines the cross contexts test to meet these objections while still allowing it to play its role in Fodor. (shrink)
Much recent work on moral responsibility and on distributive justice has addressed the concept of luck. Very little attention has been given to the relation of luck to rationality. How does luck bear on our choices? Can beliefs about luck lead to unwise decisions? These questions have particular relevance for understanding gambling behaviour, and for public policy on gambling. In this paper I argue that no one is reliably lucky, and that projecting luck can undermine rational decision-making. I give various (...) examples to show the conceptual connection between luck and unpredictability. I present an a posteriori conception of projectibility, and argue that because lucky events are rationally unexpected, regularity statements about luck fail to satisfy the conditions of projectibility. I reject the claim that ‘lucky’ is a dispositional term, and thus projectible, on the ground that a dispositional interpretation leads to contradiction. I then defend my claim that luck is not projectible against three objections. I conclude with some thoughts about rational responses to luck, using gambling as an illustration. (shrink)
Accuracy in the philosophical theory of rationality demands that we recognize particular beliefs as arising within the context of larger units, the cultural or conceptual schemes, patterns, or practices, involvement in which itself provides standards and grounds for their rational evaluation. At the same time, though, a satisfactory account of rationality cannot hold the standards, values, or commitments of one particular culture, practice, or conceptual scheme, even one’s own, immune from rational criticism. In order to accurately and responsibly picture the (...) shape of our commitments and the dynamics of their revision over time, in other words, the theory of rationality must reconcile the immanence of reason to particular cultural and conceptual units with its transcendence of them. This raises a deep and far-ranging problem of perspective. In his perspicuous presentation of it, Hilary Putnam put the problem this way: There are two points that must be balanced, both points that have been made by philosophers of many different kinds: (1) talk of what is ‘right’ and ‘wrong’ in any area only makes sense against the background of an inherited tradition; but (2) traditions themselves can be criticized … On the one hand, there is no notion of reasonableness at all without cultures, practices, procedures; on the other hand, the cultures, practices, procedures we inherit are not an algorithm to be slavishly followed. As Mill said, commenting on his own inductive logic, there is no rule book which will not lead to terrible results ‘if supposed to be conjoined with universal idiocy.’ Reason is, in this sense, both immanent (not to be found outside of concrete language games and institutions) and transcendent (a regulative idea that we use to criticize the conduct of all activities and institutions). (p. 431). As Putnam argues, it is difficult to find a standpoint of theory from which the contrasting claims of immanence and transcendence can be reconciled.. (shrink)

Abstract: C. S. Peirce's psychological analysis of belief, doubt, and inquiry provides insights into the nature of scientific knowledge.

There is good reason to suppose that our best physical theories, quantum mechanics and special relativity, are false if taken together and literally. If they are in fact false, then how should they count as providing knowledge of the physical world?

This paper presents a notion of local probable approximate truth in terms of descriptive nesting relations between current and subsequent theories. (...)

Such systems are of interest in property theory, natural language semantics, the theory of truth, theoretical computer science, the theory of classes, and category theory. While there are a variety of proposed type-free systems, there is a particularly natural type-free system that we believe is prototypical: the logic of recursive algorithms. Algorithmic logic is the study of basic statements concerning algorithms and the algorithmic rules of inference between such statements. (...) As shown in [1], the threat of paradoxes, such as the Curry paradox, requires care in implementing rules of inference in this context. As in any type-free logic, some traditional rules will fail. The first part of the paper develops a rich collection of inference rules that do not lead to paradox. The second part identifies traditional rules of logic that are paradoxical in algorithmic logic, and so should be viewed with suspicion in type-free logic generally. (shrink)
In various guises (usually referred to as the “basic emotion” or “discrete emotion” approach), scientists and philosophers have long argued that certain categories of emotion are natural kinds. In a recent paper, Colombetti (2009) proposed yet another natural kind account, and in so doing, characterized and critiqued psychological constructionist approaches to emotion, including our own Conceptual Act Model. In this commentary, we briefly address three topics raised by Columbetti. First, we correct several common misperceptions about the discrete emotion approach to (...) emotion. Second, we discuss misconceptions of our Conceptual Act Model. Finally, we briefly comment on Columbetti's Dynamical Discrete Emotion model. (shrink)
Signaling games with reinforcement learning have been used to model the evolution of term languages (Lewis 1969, Conven- tion. Cambridge, MA: Harvard University Press; Skyrms 2006, “Signals” Presidential Address. Philosophy of Science Association for PSA). In this article, syntactic games, extensions of David Lewis’s original sender– receiver game, are used to illustrate how a language that exploits available syntactic structure might evolve to code for states of the world. The evolution of a language occurs in the context of available vocabulary (...) and syntax—the role played by each component is compared in the context of simple reinforcement learning. (shrink)
In order for Bayesian inquiry to count as objective, one might argue that it must lead to a consensus among those who use it and share evidence, but presumably this is not enough. It has been proposed that one should also require that the consensus be reached from very different initial opinions by conditioning only on basic experimental evidence, evidence free from subjective, social, or psychological influence. I will argue here, however, that this notion of objectivity in Bayesian inquiry is (...) too narrow. (shrink)
Adolf Grünbaum has introduced into the literature [4], and several times revised and restated [5] [6], a description of a putative crucial experiment. The outcome of this experiment is supposed to be the conclusive falsification of an hypothesis to the effect that the geometry of a certain region of space, or of a certain surface, is Euclidean. Hereafter, in this paper, I shall refer to this example experiment, in any and all of the different versions of it that Grünbaum has (...) articulated, along with the argumentation with which he has supplemented it, as "Grünbaum's Falsification Example." I will be concerned with all versions of the experiment itself, but only with the most recent supplementary argumentation that Grünbaum has offered, since the ways in which this differs from earlier arguments reflect a taking into account, on Grünbaum's part, of points critics have raised and flaws that they have purported to find in some of those earlier arguments [7-11]. There are three separate important theses against which one or another version of Grünbaum's Falsification Example may be taken to have been directed. Each of these Grünbaum has either explicitly claimed to refute or at least left himself open to the interpretation that he has sought to refute, by means of the example. I propose to try to make clear that none of these three theses is refuted, or even threatened with counterevidence, by Grünbaum's Falsification Example. (shrink)
Pulier (2000, Theory and Decision 49: 291) and Machina (2000, Theory and Decision 49: 293) seek to dissolve the BarrettâArntzenius infinite decision puzzle (1999, Theory and Decision 46: 101). The proposed dissolutions, however, are based on misunderstandings concerning how the puzzle works and the nature of supertasks more generally. We will describe the puzzle in a simplified form, address the recent misunderstandings, and describe possible morals for decision theory.
Beller, Bender, and Medin argue that a reconciliation between anthropology and cognitive science seems unlikely. We disagree. In our view, Beller et al.’s view of the scope of what anthropology can offer cognitive science is too narrow. In focusing on anthropology’s role in elucidating cultural particulars, they downplay the fact that anthropology can reveal both variation and universals in human cognition, and is in a unique position to do so relative to the other subfields of cognitive science. Indeed, without cross-cultural (...) research, the universality of any aspect of human cognition cannot truly be established. Therefore, if the goal of cognitive science is to understand the cognitive capacities of our species as a whole, then it cannot do without anthropology. We briefly review a growing body of anthropological work aimed at answering questions about human cognition and offer suggestions for future work. (shrink)
We develop a functional abstraction principle for the type-free algorithmic logic introduced in our earlier work. Our approach is based on the standard combinators but is supplemented by the novel use of evaluation trees. Then we show that the abstraction principle leads to a Curry fixed point, a statement C that asserts C ⇒ A where A is any given statement. When A is false, such a C yields a paradoxical situation. As discussed in our earlier work, this situation leaves (...) one no choice but to restrict the use of a certain class of implicational rules including modus ponens. (shrink)
In this note, we consider constraints on the physical possibility of transfinite Turing machines that arise from how one models the continuous structure of space and time in one's best physical theories. We conclude by suggesting a version of Church's thesis appropriate as an upper bound for physical computation given how space and time are modeled on our current physical theories.
We tell a story where an agent who chooses in such a way as to make the greatest possible profit on each of an infinite series of transactions ends up worse off than an agent who chooses in such a way as to make the least possible profit on each transaction. That is, contrary to what one might suppose, it is not necessarily rational always to choose the option that yields the greatest possible profit on each transaction.
Although philosophers have long agreed that Anselm’s PROSLOGION contains what is often called the ontological argument (but not by Anselm himself), they do not agree about just what that argument is. In this paper, I do two things: (1) I set out a careful, precise statement of the argument in the PROSLOGION, taking due account of the historical, personal, philosophical, and theological contexts of Anselm’s thought. (2) Having disembarrassed the argument of some common misunderstandings and placed it in its proper (...) setting, I argue that it is more complicated and much stronger than all but a very few philosophers have realized.

α-recursion lifts classical recursion theory from the first transfinite ordinal ω to an arbitrary admissible ordinal α [10]. Idealized computational models for α-recursion analogous to Turing machine models for classical recursion have been proposed and studied [4] and [5] and are applicable in computational approaches to the foundations of logic and mathematics [8]. They also provide a natural setting for modeling extensions of the algorithmic logic described in [1] and [2]. On such models, an α-Turing machine can complete a θ-step (...) computation for any ordinal θ < α. Here we consider constraints on the physical realization of α-Turing machines that arise from the structure of physical spacetime. In particular, we show that an α-Turing machine is realizable in a spacetime constructed from R only if α is countable. While there are spacetimes where uncountable computations are possible and while they may even be empirically distinguishable from a standard spacetime, there is good reason to suppose that such nonstandard spacetimes are nonphysical. We conclude with a suggestion for a revision of Church’s thesis appropriate as an upper bound for physical computation. (shrink)
On Bohm''s formulation of quantum mechanics particles always have determinate positions and follow continuous trajectories. Bohm''s theory, however, requires a postulate that says that particles are initially distributed in a special way: particles are randomly distributed so that the probability of their positions being represented by a point in any regionR in configuration space is equal to the square of the wave-function integrated overR. If the distribution postulate were false, then the theory would generally fail to make the right statistical (...) predictions. Further, if it were false, then there would at least in principle be situations where a particle would approach an eigenstate of having one position but in fact always be somewhere very different. Indeed, we will see how this might happen even if the distribution postulate were true. This will help to show how loose the connection is between the wave-function and the positions of particles in Bohm''s theory and what the precise role of the distribution postulate is. Finally, we will briefly consider two attempts to formulate a version of Bohm''s theory without the distribution postulate. (shrink)
