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.

Presents a new way of looking at what it means to be human, offering a convincing case that humans are more than immaterial souls or "biological computers".

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.

In this paper a look is taken at the relatively new area of culturing neural tissue and embodying it in a mobile robot platform—essentially giving a robot a biological brain. Present technology and practice is discussed. New trends and the potential effects of and in this area are also indicated. This has a potential major impact with regard to society and ethical issues and hence some initial observations are made. Some initial issues are also considered with regard to the potential (...) consciousness of such a brain. (shrink)

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)

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)

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)

Emerging cybertechnologies, such as social digibots, bend epistemological conventions of life and culture already complicated by human and animal relationships. Virtually-augmented niches of machines and organic life promise new free-energy-governed selection of intelligent digital life. These provocative eco-evolutionary contexts demand a theory of (natural and artificial) minds to characterize and validate the immersive social phenomena universally-shaping cultural affordances.

In lieu of an abstract, here is a brief excerpt of the content:LIGHT AND METAPHOR IN PLOTINUS AND ST. THOMAS AQUINAS KEVIN CORRIGAN St. Thomas More College University of Saskatchewan Saskatoon, Saskatchewan I HAVE TWO CONCERNS in this paper. The first is a broad concern, related to the nature of metaphor, which stems from the destructionist or deconstructionist tendencies in some contemporary phenomenology or phenomenological existentialism. According to these views, the logocentric emphasis of the Western tradition must be shown (...) for what it really is : an attempt to erect a cover upon a fundamental absence. In Nietzsche's well known view, "truths are illusions of which one has forgotten that they are illusions; worn-out metaphors which have become powerless to affect the senses, coins which have their obverse effaced and now are no longer of account as coins but merely as metal." 1 For Jacques Derrida all metaphoricity is caught up in an endless circle, which precludes any privileged vantage-point from which one might determine order, hierarchy and center-point. In particular, the unique heliotropic metaphor which, in Derrida's polemic, determines the whole course of Western philosophy " from the Platonic eidos to the Hegelian idea" 2 rests only upon the infinite absence of circularity, for the movement of transference " which turns the sun into metaphor " also inevitably "turns philosophical metaphor towards the sun." 3 1 Nietzsche, "On Truth and Falsity in their Ultramoral Sense (1873)," Works 2 (New York: Russell and Russell, 1964), p. 180. 2 J. Derrida, "White Mythology", trans. F. C. T. Moore, New Literary History 6 (1974), 1: 5-74 ["La mythologie blanche" in Rhetorique et philosophie, Poetique 5 (Paris: Editions du Seliu, 1971)], p. 55. a Ibid., p. 51. 187 188 KEVIN CORRIGAN In this paper I shall examine the thought of Plotinus and Aquinas, broadly described as idealist and realist respectively, with a view to determining whether or not this transference from the physical to the metaphysical is only an illicit, covert erasure of the material sense and a forgetting that all metaphor is self-implicating, that there is no non-metaphorical standpoint from which to grasp the order and structure of the metaphorical. My second concern is much more specific. It is, first, to compare Plotinus and Aquinas on light and metaphor-two thinkers who might be considered to be poles apart on these questions: on the one hand, Plotinus, the father of Neoplatonic emanationism with its insistence upon the primacy of divine light and the father, surely too, of the tradition of light-metaphysics in the later, mediaeval period; on the other hand, St. Thomas, staunchly realist in the Aristotelian tradition. Second, I will seek to show that this first impression of the gulf between the two thinkers is not borne out by a close textual analysis, and that their respective theories, despite the admitted significant difference in viewpoint, are in some respects very close indeed. Let us look briefly at the light-metaphysics tradition first. For Robert Grosseteste light is the source of all activity and its diffusion is not a material change or a change in place, but rather an instantaneous and substantial multiplication of itself in three dimensions.4 Thus, for the author of the De Intelligentiis light is the fundamental principle of motion and life: " Est autem prima lucis operatio in sensibilibus quad motum et vitam operatur in viventibus." 5 Since light is the noblest of corporeal things, it therefore has an intermediate place between pure form and matter, and for Grosseteste and also Bonaventure it is consequently named the forma corporeitatis, the fundamental form of body as 4 De philosophischen W erke des Robert Grosseteste, ed. Ludwig Baur, in Clemens Baeumker, Beitriige zur Geschichte der Philosophic des Mittelalters, vol.

PLOTINUS AND ST. THOMAS AQUINAS 189 such, since light introduces dimension into matter. Light then is the substantial form of the physical universe.6 But how is physical light related to spiritual light? For the light-metaphysics tradition, spiritual light (whether the Uncreated Light which is God himself or the... (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 paper, I examine the terms on which John Simmons rejects all arguments for a moral obligation to obey the law and so defends “philosophical anarchism.” Although I accept his rejection of several criteria on which others might and often do insist, I criticize his reliance on the conditions of “generality” and “particularity.” In doing so, I propose an alternative to his influential conception of legitimacy.

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)

This research contributes to emergent theories on subject formation by showing how community garden participants in a small rural town in Northern Peru came to embrace a set of ideas and practices related to organic agriculture. Most CG scholarship describes the myriad benefits for participants and their communities, as well as individuals’ motivations for wanting to grow their own food. Relatively little research has explored how various kinds of gardens and their organizers produce subjects. Drawing from scholarship on community gardens (...) and subject formation, I examine the emergence of what I call an “organic subjectivity” among garden participants. Based on interviews and fieldwork conducted in Peru, I argue that the making of organic subjects in the CG is the result of three primary influences: the changing agrarian context in the community marked by the adoption of conventional farming practices, the influence of the garden organizer as the agent of an organic ideology, and the material practices associated with CG participation. This case study reinforces the notion that CGs produce subjects and that such subjects could well be oriented towards an agenda of progressive agrarian change that promotes environmental awareness and ecological farming practices, key elements of emerging alternative food networks in the global North and South.

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.

This article is based on an analysis of two types of argument, called utilitarian and educational respectively, which are commonly used to justify the teaching of modern/foreign languages in schools. Serious flaws are identified in the utilitarian arguments often employed to defend the teaching of modern languages and different educational arguments which might be offered as justification for their inclusion in the school curriculum are distinguished and appraised. The paper concludes with a consideration of the implications of the foregoing analysis (...) for the place of modern languages in the school curriculum. (shrink)

Presburger arithmetic is the first-order theory of the natural numbers with addition. We characterize sets that can be defined by a Presburger formula as exactly the sets whose characteristic functions can be represented by rational generating functions; a geometric characterization of such sets is also given. In addition, ifp= are a subset of the free variables in a Presburger formula, we can define a counting functiong to be the number of solutions to the formula, for a givenp. We show that (...) every counting function obtained in this way may be represented as, equivalently, either a piecewise quasi-polynomial or a rational generating function. Finally, we translate known computational complexity results into this setting and discuss open directions. (shrink)

This book brings together a selection of Kevin Corrigan's works published over the course of some 27 years. Its predominant theme is the encounter with otherness in ancient, medieval and modern thought and it ranges in scope from the Presocratics through Plato, Aristotle, Plotinus and the late ancient period, on the one hand, and early Christian thought, especially Gregory of Nyssa, Augustine and, much later, Aquinas, on the other.

Intensive care units are challenging and technologically advanced environments. Dealing with situations that have an ethical dimension is an intrinsic part of working in such a milieu. When a moral dilemma emerges, it can cause anxiety and unease for all staff involved with it. Theoretical and abstract papers reveal that having to confront situations of ethical difficulty is a contributory factor to levels of poor morale and burnout among critical care staff. Despite this, there is a surprising dearth of published (...) nursing research in the UK that investigates how staff deal with ethical issues in intensive care units. The purpose of this paper is to explore and discuss the development of a research framework designed to explore how staff deal with moral dilemmas in a British inten sive care unit. (shrink)

This essay explores Thomas Browne's Pseudodoxia epidemica, with its lengthy book on 'errors' in animal lore. In the limited critical literature on Browne's natural history, this author is generally seen as stumbling towards a zoological idiom and clearing away the emblematic 'clutter' of earlier writers on natural history—Gesner, Aldrovandi, Topsell or Franzius. This essay proposes that Browne is working with a more complex set of co-ordinates in his thought, beyond his experimental inclinations and his Aristotelian assumptions. It will explore the (...) extent to which his studies of animals emerge from, and duplicate, the presumptions of his biblical hermeneutics, and it will suggest that Browne regularly exports terms from scriptural exegesis—the categories of the literal, the figurative, and the emblematic—into his investigations of the natural world.

This article examines Śāntarakṣita’s and Kamalaśīla’s understandings of svatantra and prasaṅga proofs in the attempt to clarify how and why Tibetan Prāsaṅgikas came to portray svatantra inference as an instance of the very thing Madhyamaka rejects. The article proceeds in four parts. A brief comparison of Patsap Nyimadrak’s portrayal of svatantra inference with Bhāviveka’s and Candrakīrti’s employment of this expression shows that Patsap expanded the meaning of it, charging its users with embracing a realism at odds with Madhyamaka emptiness. Patsap’s (...) arguments against Śāntarakṣita’s “neither one nor many” proof lead us consider the latter’s and Kamalaśīla’s understanding of svatantra and prasaṅga proofs, which turns out to be consistent with, if more sophisticated than, Bhāviveka’s and Candrakīrti’s usage. An exploration of Kamalaśīla’s development of the proof of the naturelessness of all things, real and imagined, calls into question the svatantra-prasaṅga distinction but still leaves us without a source for Patsap’s characterization. A consideration of Śāntarakṣita’s and Kamalaśīla’s use of svatantra to characterize Mīmāṃsā conceptions of an authorless Veda and “intrinsic validity,” as well as their own view of “self-awareness,” offers potential sources for characterizing valid cognition and, by extension, inference as “autonomous.”.
