According to some recent arguments, if our moral beliefs are products of natural selection, then we do not have moral knowledge. In defense of this inference, its proponents argue that natural selection is a process that fails to track moral facts. In this paper, I argue that our having moral knowledge is consistent with, the hypothesis that our moral beliefs are products of natural selection, and the claim that natural selection fails to track moral facts. I also argue that natural (...) selection is a process that could track moral facts, albeit imperfectly. I do not argue that we do have moral knowledge. I argue instead that Darwinian considerations provide us with no reason to doubt that we do, and with some reasons to suppose that we might. (shrink)

I argue that the idea of ‘quasi-independence’ [Lewontin, R. C. . Adaptation. Scientific American, 239, 212–230] cannot be understood without attending to the distinction between fitness and advantageousness [Sober, E. . Philosophy of biology. Boulder: Westview Press]. Natural selection increases the frequency of fitter traits, not necessarily of advantageous ones. A positive correlation between an advantageous trait and a disadvantageous one may prevent the advantageous trait from evolving. The quasi-independence criterion is aimed at specifying the conditions under which advantageous traits (...) will evolve by natural selection in this type of situation. Contrary to what others have argued [Sterelny, K. . Evolutionary explanations of human behavior. Australian Journal of Philosophy, 70, 156–172, and Sterelny, K., & Griffiths, P. . Sex and death. Chicago: University of Chicago Press], these conditions must involve a precise quantitative measure of the extent to which advantageous traits are beneficial, and the degree to which they are correlated with other traits. Driscoll [Driscoll, C. . Can behaviors be adaptations? Philosophy of Science, 71, 16–35] recognizes the need for such a measure, but I argue that she does not provide the correct formulation. The account of quasi-independence that I offer clarifies this point. (shrink)

We are grateful to the commentators for taking the time to respond to our article. Too many interesting and important points have been raised for us to tackle them all in this response, and so in the below we have sought to draw out the major themes. These include problems with both the term ‘ultimate causation’ and the proximate-ultimate causation dichotomy more generally, clarification of the meaning of reciprocal causation, discussion of issues related to the nature of development and phenotypic (...) plasticity and their roles in evolution, and consideration of the need for an extended evolutionary synthesis.

According to H.L.A. Hart's analysis, to utter an internal legal statement is partly to express an acceptance of a set of norms. This article attempts to defend Hart's conception of internal legal discourse by responding to the following three lines of criticism that can be found in Joseph Raz's writings: (i) that Hart's analysis fails to account for what Raz calls ‘detached legal statements’; (ii) that Hart's deployment of the notion of acceptance in his analysis vitiates his legal positivist project (...) because such acceptance necessarily amounts to moral endorsement; and (iii) that Hart is wrong to assume that normative practices, including discursive legal practices, can be characterized satisfactorily by deploying only descriptive statements. I argue that Hart's theory, or at least a theory along the lines that Hart developed, has sufficient resources to handle satisfactorily these criticisms. His world is a noonday world in which sharply outlined figures, most of them more than a little singular, act in describable ways against perceptible backgrounds.

Bayesian reasoning has been applied formally to statistical inference, machine learning and analysing scientific method. Here I apply it informally to more common forms of inference, namely natural language arguments. I analyse a variety of traditional fallacies, deductive, inductive and causal, and find more merit in them than is generally acknowledged. Bayesian principles provide a framework for understanding ordinary arguments which is well worth developing.

The idea of moral responsibility is central to a wide range of our moral, social, and legal practices, and it underpins our basic notion of culpability. Yet the idea of moral responsibility is increasingly viewed with skepticism by researchers and scholars in psychology, neuroscience, philosophy, and the law. Building Better Beings: A Theory of Moral Responsibility responds to these challenges, offering a new account of the justification of our practices and judgments of moral responsibility. Three distinctive ideas shape the account. (...) The first is the agency cultivation model, which holds that a system of responsibility practices can derive its justification from the way it supports our agency. The second idea, circumstantialism, is a new way of thinking about agential capacities. This is the view that the capacities required for moral responsibility are functions of agents in circumstances, rather than basic features of agents considered in themselves. The third idea is revisionism, or the idea that a satisfactory theory of moral responsibility will conflict with some aspects of ordinary commitments about freedom and moral responsibility. (shrink)

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. ‘Yet the answer is a prosaic one: don’t ask what time is but how the word ‘time’ is being used’.Friedrich Waismann.I miss the future.Jaron Lanier.

A series of imitation games involving 3-participant (simultaneous comparison of two hidden entities) and 2-participant (direct interrogation of a hidden entity) were conducted at Bletchley Park on the 100th anniversary of Alan Turing’s birth: 23 June 2012. From the ongoing analysis of over 150 games involving (expert and non-expert, males and females, adults and child) judges, machines and hidden humans (foils for the machines), we present six particular conversations that took place between human judges and a hidden entity that produced (...) unexpected results. From this sample we focus on features of Turing’s machine intelligence test that the mathematician/code breaker did not consider in his examination for machine thinking: the subjective nature of attributing intelligence to another mind.

: Bioethics has focused on the areas of individual ethical choices--patient care--or public policy and law. There are, however, important arenas for ethical choices that have been overlooked. Health care is populated with intermediate arenas such as hospitals, nursing homes, hospices, and health care systems. This essay argues that bioethics needs to develop a language and concepts for institutional ethics. A first step in this direction is to think about institutional conscience.

The Lottery Paradox has been thought to provide a reductio argument against probabilistic accounts of inductive inference. As a result, much work in artificial intelligence has concentrated on qualitative methods of inference, including default logics, which are intended to model some varieties of inductive inference. It has recently been shown that the paradox can be generated within qualitative default logics. However, John Pollock's qualitative system of defeasible inference, does avoid the Lottery Paradox by incorporating a rule designed specifically for that (...) purpose. I shall argue that Pollock's system instead succumbs to a worse disease: it fails to allow for induction at all. (shrink)

This volume presents 15 studies occasioned by the 500th anniversary of the European discovery of America. It covers both the initial encounters between the Europeans and native Americans and the golden age of Hispanic philosophy that followed the discovery - specifically between 1500 and 1650.

Explanation and evidence are related in one way that is uncontroversial: evidence can confirm or disconfirm explanations. One explanation of Sally’s cold is that she has a virus; another is that she has a bacterial infection. The available evidence confirms the virus explanation because the evidence supports that colds are caused by viruses, not bacteria. A more interesting question concerns whether explanatory facts themselves provide evidence. That is to say, do we get evidence for p simply by realizing that p, (...) if true, would explain some data? Explanationists answer this question affirmatively, maintaining that explanatoriness is evidence of truth. (shrink)

ABSTRACT In a series of papers read to the Cambridge Philosophical Society through the 1820s, the Cambridge mathematician George Peacock laid the foundation for a natural history of arithmetic that would tell a story of human progress from counting to modern arithmetic. The trajectory of that history, Peacock argued, established algebraic analysis as a form of universal reasoning that used empirically warranted operations of mind to think with symbols on paper. The science of counting would suggest arithmetic, arithmetic would suggest (...) arithmetical algebra, and, finally, arithmetical algebra would suggest symbolic algebra. This philosophy of suggestion provided the foundation for Peacock's “principle of equivalent forms,” which justified the practice of nineteenth-century English symbolic algebra. Peacock's philosophy of suggestion owed a considerable debt to the early Cambridge Philosophical Society culture of natural history. The aim of this essay is to show how that culture of natural history was constitutively significant to the practice of nineteenth-century English algebra. (shrink)

According to a widely held view, people's commitments to laws are dependent on the existence in their community of a conventional practice of complying with certain fundamental laws. This conventionalism has significantly hampered our attempts to explain the normative practice of law. Ronald Dworkin has argued against conventionalism by bringing up the phenomenon of persistent fundamental legal controversies, but neither Dworkin nor his legal positivist respondents have correctly understood the real significance of such controversies. This article argues that such controversies (...) pose a deep challenge to any conception of our legal practice as a genuinely normative, rule-mediated, practice. The article also argues that what is needed to deflect this challenge is a new understanding – different from the widely held conventionalist understanding – of how people's commitments to laws are predicated on their fellows’ like commitments.

I have applied a fairly general, learning theoretic perspective to some questions raised by Reichenbach's positions on induction and discovery. This is appropriate in an examination of the significance of Reichenbach's work, since the learning-theoretic perspective is to some degree part of Reichenbach's reliabilist legacy. I have argued that Reichenbach's positivism and his infatuation with probabilities are both irrelevant to his views on induction, which are principally grounded in the notion of limiting reliability. I have suggested that limiting reliability is (...) still a formidable basis for the formulation of methodological norms, particularly when reliability cannot possibly be had in the short run, so that refined judgments about evidential support must depend upon measure-theoretic choices having nothing to do in the short run with the truth of the hypothesis under investigation. To illustrate the generality of Reichenbach's program, I showed how it can be applied to methods that aim to solve arbitrary assessment and discovery problems in various senses. In this generalized Reichenbachian setting, we can characterize the intrinsic complexity of reliable inductive inference in terms of topological complexity. Finally, I let Reichenbach's theory of induction have the last say about hypothetico-deductive method. (shrink)

According to reductionists about agency, an agent’s bringing something about is reducible to states and events involving the agent bringing something about. Many have worried that reductionism cannot accommodate robust forms of agency, such as self-determination. One common reductionist answer to this worry contends that self-determining agents are identified with certain states and events, and so these states and events causing a decision counts as the agent’s self-determining the decision. In this paper I discuss J. David Velleman’s identification reductionist theory, (...) according to which an agent is identified with his desire to make most sense of himself. I develop two constraints that an adequate identification reductionist theory must satisfy and show that Velleman’s theory cannot satisfy both. In particular, I argue that Velleman’s account founders on cases of self-determined self-transformation. (shrink)

Elaine Scarry argues in The Body in Pain that war is a vast and reciprocal swearing on the body, with corporeality key not only to its brutal prosecution but also to the eventual ending of the political ‘crisis of substantiation’ that war entails. However, her work has not been extensively explored with reference to significant transformations in the embodied experiences of contemporary warfare. This article thus analyses a particular articulation of late modern warfare that I term predatory war, whose current (...) signature motif is the drone strike, through the lens of Scarry’s work. Here, the associated modes of embodiment are radically non-reciprocal, the woundscapes of conflict are profoundly asymmetric, and the affective mediation of bodily injury does not substantiate any ending to the conflict. As such, I argue that the ontology and phenomenology of predatory war increasingly resembles what Scarry identifies as the underlying structure of torture. (shrink)

Was David Hume radically sceptical about our attempts to understand the world or was he merely approaching philosophical problems from a scientific perspective? Most philosophers today believe that Hume's outlook was more scientific than radically sceptical and that his scepticism was more limited than previously supposed. If these philosophers are correct, then Hume's approach to philosophy mirrors the approach of many contemporary philosophers. This similarity between Hume and many aspects of contemporary philosophy suggests that we should try to understand Hume (...) not as an historical relic but as a partner in a continuing philosophical dialogue. When we look closely at Hume's thoughts about human understanding, we find that Hume's scepticism emerges very insistently in the context of Hume's scientific approach. This book tries to come to terms with Hume's scepticism in a way that sheds light on contemporary philosophy and its relationship to science. (shrink)

Wittgenstein was centrally concerned with the puzzling nature of the mind, mathematics, morality and modality. He also developed innovative views about the status and methodology of philosophy and was explicitly opposed to crudely "scientistic" worldviews. His later thought has thus often been understood as elaborating a nuanced form of naturalism appealing to such notions as "form of life", "primitive reactions", "natural history", "general facts of nature" and "common behaviour of mankind". And yet, Wittgenstein is strangely absent from much of the (...) contemporary literature on naturalism and naturalising projects. This is the first collection of essays to focus explicitly on the relationship between Wittgenstein and naturalism. The volume is divided into four sections, each of which addresses a different aspect of naturalism and its relation to Wittgenstein's thought. The first section considers how naturalism could or should be understood. The second section deals with some of the main problematic domains—consciousness, meaning, mathematics—that philosophers have typically sought to naturalise. The third section explores ways in which the conceptual nature of human life might be continuous in important respects with animals. The final section is concerned with the naturalistic status and methodology of philosophy itself. This book thus casts a fresh light on many classical philosophical issues and brings Wittgensteinian ideas to bear on a number of current debates-for example experimental philosophy, neo-pragmatism and animal cognition/ethics-in which naturalism is playing a central role.

We further develop the mathematical theory of causal interventions, extending earlier results of Korb, Twardy, Handfield, & Oppy, (2005) and Spirtes, Glymour, Scheines (2000). Some of the skepticism surrounding causal discovery has concerned the fact that using only observational data can radically underdetermine the best explanatory causal model, with the true causal model appearing inferior to a simpler, faithful model (cf. Cartwright, (2001). Our results show that experimental data, together with some plausible assumptions, can reduce the space of viable explanatory (...) causal models to one. (shrink)

My point of departure is the idea that Wittgenstein's work, especially his later work with its explicit emphasis on practices, seeks to engage a reader who is likely to come to philosophy with a certain cast of mind that includes unexamined commitments from a particular cultural context. I show how a substantial number of remarks by Wittgenstein in which he addresses cultural topics bring out the importance of the quite specific connections he saw between the philosophical problems with which he (...) grappled and the historical cultural context in which those problems have arisen. Not only is a grasp of this aspect of his writing integral to a proper understanding of Wittgenstein as a thinker, bringing out these connections serves to put these remarks into a coherent conceptual framework. In assessing the relation of Wittgenstein's cultural concerns to his engagement with metaphysics, I show how his development of Spengler's thought is an important connecting link. Particularly important for this analysis will be my discussion of Wittgenstein's understanding and employment of the concept of a Betrachtungsform , as well as a few closely related concepts. I then offer an interpretation of what I believe to be the significance of the connection in his later thought between his philosophical activity and his views about the modern West. (shrink)

The paper assumes for its starting point the basic correctness of the so-called “resolute” reading of Wittgenstein's Tractatus, a reading first developed by Cora Diamond and James Conant. The main part of the paper concerns the consequences this interpretation will have for our understanding of Wittgenstein's well-known remark in a letter to a prospective publisher that the point or aim of his book was an ethical one. I first give a sketch of what, given the committments of the resolute reading, (...) the ethical point of the book will be, and then argue that given these committments and Wittgenstein's own philosophical biases at the time he wrote the Tractatus, the book cannot serve the ethical purpose for which it was written.

In this article I offer an account and analysis of several patterns of valuation of the cardinal directions in medieval Scandinavian texts. While my topic is not altogether novel—ideas about space, along with those of time, have been matters of widespread and perennial concern to scholars of culture and religion, and those interested in the Norse context have proven no exception—I seek to go beyond previous examinations in several ways. First, many of the scholars who have focused on directionality in (...) Old Norse sources have been concerned with catalogu-ing and elucidating terminology for the cardinal points and for movement along and between them, with a particular emphasis on assessing the “correctness” of such terms' application in respect to ultimate or relative orientation. While I draw on the insights of such studies, my interests lie less in efforts to map or to describe movement in the real world known to medieval Scandinavians than in the values that they can be shown to have attached to the cardinal directions. My focus, therefore, is on imagined or moral as opposed to physical or topographical space. Of the studies that have taken a similar interest in Norse ideas about space, most have focused mainly or exclusively on the attempt, often from a structuralist perspective, to reconstruct from available sources pagan cosmography, to discover or assemble a systematic summa of the pre-Christian Norse mythical Weltbild. While pre-Christian ideas, or their traces, are also a focus of my article, I pay more than equal attention to conceptualizations and valuations of space held by Christian northerners. “Mythical,” then, is not a label that I reserve for heathen or patently fantastic materials but one under which I also subsume data from Christian and historiographical sources.

This paper concerns the widely discussed exchange between Hubert Dreyfus and John McDowell that took place a few years back. The author first provides a brief sketch of how McDowell’s practice of philosophy for the last twenty or so years is best described as “quietist” in the spirit of the later Wittgenstein. Next, he shows that this exchange with Dreyfus is best understood as carried on largely in this spirit as well, even though McDowell somewhat inexplicably fails to acknowledge this (...) point in the course of the dispute. Finally and most importantly, the author shows how, somewhat ironically, the dispute takes a turn that suggests a remaining tension in McDowell’s own thought about the nature of philosophy. This tension comes out in his unwillingness to relinquish, or at least set aside temporarily, important parts of the traditional philosophical vocabulary that seem to be getting in the way in his dispute with Dreyfus. At the broadest level, the paper concerns difficulties with attempts to overcome the metaphysical tradition, and the role of the tradition’s vocabulary in such attempts, even in a discussion between two skilled philosophers who both have great sympathy for such a project.

A finite data set is consistent with infinitely many alternative theories. Scientific realists recommend that we prefer the simplest one. Anti-realists ask how a fixed simplicity bias could track the truth when the truth might be complex. It is no solution to impose a prior probability distribution biased toward simplicity, for such a distribution merely embodies the bias at issue without explaining its efficacy. In this note, I argue, on the basis of computational learning theory, that a fixed simplicity bias (...) is necessary if inquiry is to converge to the right answer efficiently, whatever the right answer might be. Efficiency is understood in the sense of minimizing the least fixed bound on retractions or errors prior to convergence. (shrink)
