Computer-based argument mapping greatly enhances student critical thinking, more than tripling absolute gains made by other methods. I describe the method and my experience as an outsider. Argument mapping often showed precisely how students were erring (for example: confusing helping premises for separate reasons), making it much easier for them to fix their errors.

We present a probabilistic extension to active path analyses of token causation (Halpern & Pearl 2001, forthcoming; Hitchcock 2001). The extension uses the generalized notion of intervention presented in (Korb et al. 2004): we allow an intervention to set any probability distribution over the intervention variables, not just a single value. The resulting account can handle a wide range of examples. We do not claim the account is complete --- only that it fills an obvious gap in previous active-path approaches. (...) It still succumbs to recent counterexamples by Hiddleston (2005), because it does not explicitly consider causal processes. We claim three benefits: a detailed comparison of three active-path approaches, a probabilistic extension for each, and an algorithmic formulation. (shrink)

James McAllister’s 2003 article, “Algorithmic randomness in empirical data” claims that empirical data sets are algorithmically random, and hence incompressible. We show that this claim is mistaken. We present theoretical arguments and empirical evidence for compressibility, and discuss the matter in the framework of Minimum Message Length (MML) inference, which shows that the theory which best compresses the data is the one with highest posterior probability, and the best explanation of the data.

The investigation of probabilistic causality has been plagued by a variety of misconceptions and misunderstandings. One has been the thought that the aim of the probabilistic account of causality is the reduction of causal claims to probabilistic claims. Nancy Cartwright (1979) has clearly rebutted that idea. Another ill-conceived idea continues to haunt the debate, namely the idea that contextual unanimity can do the work of objective homogeneity. It cannot. We argue that only objective homogeneity in combination with a causal interpretation (...) of Bayesian networks can provide the desired criterion of probabilistic causality. (shrink)

This paper presents an attempt to integrate theories of causal processes—of the kind developed by Wesley Salmon and Phil Dowe—into a theory of causal models using Bayesian networks. We suggest that arcs in causal models must correspond to possible causal processes. Moreover, we suggest that when processes are rendered physically impossible by what occurs on distinct paths, the original model must be restricted by removing the relevant arc. These two techniques suffice to explain cases of late preëmption and other cases (...) that have proved problematic for causal models. (shrink)

We present a minimum message length (MML) framework for trajectory partitioning by point selection, and use it to automatically select the tolerance parameter ε for Douglas-Peucker partitioning, adapting to local trajectory complexity. By examining a range of ε for synthetic and real trajectories, it is easy to see that the best ε does vary by trajectory, and that the MML encoding makes sensible choices and is robust against Gaussian noise. We use it to explore the identification of micro-activities within a (...) longer trajectory. This MML metric is comparable to the TRACLUS metric – and shares the constraint of abstracting only by omission of points – but is a true lossless encoding. Such encoding has several theoretical advantages – particularly with very small segments (high frame rates) – but actual performance interacts strongly with the search algorithm. Both differ from unconstrained piecewise linear approximations, including other MML formulations. (shrink)

There is a need to rapidly assess the impact of new technology initiatives on the Counter Improvised Explosive Device battle in Iraq and Afghanistan. The immediate challenge is the need for rapid decisions, and a lack of engineering test data to support the assessment. The rapid assessment methodology exploits available information to build a probabilistic model that provides an explicit executable representation of the initiative’s likely impact. The model is used to provide a consistent, explicit, explanation to decision makers on (...) the likely impact of the initiative. Sensitivity analysis on the model provides analytic information to support development of informative test plans. (shrink)

Artificial Intelligence (AI) and Philosophy of Science share a fundamental problem—that of understanding causality. Bayesian network techniques have recently been used by Judea Pearl in a new approach to understanding causality and causal processes (Pearl, 2000). Pearl’s approach has great promise, but needs to be supplemented with an explicit account of causal interaction. Thus far, despite considerable interest, philosophy has provided no useful account of causal interaction. Here we provide one, employing the concepts of Bayesian networks. With it we demonstrate (...) the failure of one of philosophy’s more sophisticated attempts to deal with the concept of causal interaction, that of Ellery Eells’ Probabilistic Causality (1991).

Paper presented to the Twenty-seventh Hume Society Conference, 26 July 2000, Williamsburg, Virginia. -/- At the time I thought there was a stronger link between Maclaurin and Hume, but in discussions at and after the meeting, decided Hume was not taking his mechanics out of Maclaurin’s Account. Although I still have found Maclaurin useful in interpreting Hume -- see Sapadin 1997 for a discussion of popular Newtonianism in Hume's day -- I suspect my draft suffers somewhat from ambivalence. There are (...) still similarities, and possible avenues of influence, arguing that Hume was not ignorant of the new mechanics, but it also becomes clear that he did not understand it: although he adopts the Newtonian measure of force, he misapplies it.

Part of our fascination with the Maya can be attributed to the fact that they were literate . . . that is, the Classic Maya possessed a visible language that consisted of letters and a grammar, and one of the products of their literacy was the book. (Aveni 1992b, p.3).

Artificial Intelligence (AI) and Philosophy of Science share a fundamental problem—understanding causality. Bayesian networks have recently been used by Judea Pearl in a new approach to understanding causality (Pearl, 2000). Part of understanding causality is understanding causal interaction. Bayes nets can represent any degree of causal interaction, and researchers normally try to limit interactions, usually by replacing the full CPT with a noisy-OR function. But we show that noisy-OR and another common model are merely special cases of the general linear (...) systems definition of noninteraction. However, they apply in different situations, and we can measure the degree of causal interaction relative to any such model. (shrink)

Using Bayesian network causal models, we provide a simple general account of probabilistic causal interaction. We also detail problems in the leading accounts by Ellery Eells, and any others which require valence reversals, contextual unanimity, or average effects.

The place of religion in society has changed profoundly in the last few centuries, particularly in the West. In what will be a defining book for our time, Taylor takes up the question of what these changes mean, and what, precisely, happens when a society becomes one in which faith is only one human possibility among others.

One of science's greatest intellects examines how people and animals display fear, anger, and pleasure. Darwin based this 1872 study on his personal observations, which anticipated later findings in neuroscience. Abounding in anecdotes and literary quotations, the book is illustrated with 21 figures and seven photographic plates. Its direct approach, accessible to professionals and amateurs alike, continues to inspire and inform modern research in psychology.

Charles Taylor has been one of the most original and influential figures in contemporary philosophy: his 'philosophical anthropology' spans an unusually wide range of theoretical interests and draws creatively on both Anglo-American and Continental traditions in philosophy. A selection of his published papers is presented here in two volumes, structured to indicate the direction and essential unity of the work. He starts from a polemical concern with behaviourism and other reductionist theories (particularly in psychology and the philosophy of language) (...) which aim to model the study of man on the natural sciences. This leads to a general critique of naturalism, its historical development and its importance for modern culture and consciousness; and that in turn points, forward to a positive account of human agency and the self, the constitutive role of language and value, and the scope of practical reason. The volumes jointly present some two decades of work on these fundamental themes, and convey strongly the tenacity, verve and versatility of the author in grappling with them. They will interest a very wide range of philosophers and students of the human sciences. (shrink)

This new edition of Charles Fried's 'Medical Experimentation' includes a general introduction by Franklin Miller and the late Alan Wertheimer, a reprint of the 1974 text, an in-depth analysis by Harvard Law School scholars I. Glenn Cohen and D. James Greiner, and a new essay by Fried reflecting on the original text and how it applies to the contemporary landscape of medicine and medical experimentation.

In this revised edition of his 1979 classic Political Theory and International Relations, Charles Beitz rejects two highly influential conceptions of international theory as empirically inaccurate and theoretically misleading. In one, international relations is a Hobbesian state of nature in which moral judgments are entirely inappropriate, and in the other, states are analogous to persons in domestic society in having rights of autonomy that insulate them from external moral assessment and political interference. Beitz postulates that a theory of international (...) politics should include a revised principle of state autonomy based on the justice of a state’s domestic institutions, and a principle of international distributive justice to establish a fair division of resources and wealth among persons situated in diverse national societies.

Familiarity with Charles Darwin's treatise on evolution is essential to every well-educated individual. One of the most important books ever published--and a continuing source of controversy, a century and a half later--this classic of science is reproduced in a facsimile of the critically acclaimed first edition.

Perhaps the most readable and accessible of the great works of scientific imagination, The Origin of Species sold out on the day it was published in 1859. Theologians quickly labeled Charles Darwin the most dangerous man in England, and, as the Saturday Review noted, the uproar over the book quickly "passed beyond the bounds of the study and lecture-room into the drawing-room and the public street." Yet, after reading it, Darwin's friend and colleague T. H. Huxley had a different (...) reaction: "How extremely stupid not to have thought of that." Based largely on Darwin's experience as a naturalist while on a five-year voyage aboard H.M.S. Beagle, The Origin of Species set forth a theory of evolution and natural selection that challenged contemporary beliefs about divine providence and the immutability of species. A landmark contribution to philosophical and scientific thought, this edition also includes an introductory historical sketch and a glossary Darwin later added to the original text. Charles Darwin grew up considered, by his own account, "a very ordinary boy, rather below the common standard of intellect." A quirk of fate kept him from the career his father had deemed appropriate--that of a country parson--when a botanist recommended Darwin for an appointment as a naturalist aboard H.M.S. Beagle from 1831 to 1836. Darwin is also the author of the five-volume work Zoology of the Voyage of the Beagle (1839) and The Descent of Man (1871). (shrink)

The publication of Darwin's On the Origin of Species in 1859 ignited a public storm he neither wanted nor enjoyed. Having offered his book as a contribution to science, Darwin discovered to his dismay that it was received as an affront by many scientists and as a sacrilege by clergy and Christian citizens. To answer the criticism that his theory was a theory only, and a wild one at that, he published two volumes in 1868 to demonstrate that evolution was (...) obvious to anyone who cared to look at a bull in a pasture or a dog on a hearth. In response to those who insisted that species were distinct since creation, Darwin pointed to breeders of pigs and pigeons. In reply to those who protested that human intervention is one thing and natural selection another, he argued, "If organic beings had not possessed an inherent tendency to vary, man could have done nothing." To counter those who scorned his descriptions of species in exotic places, he submitted local evidence of cabbages and cauliflower. Based on a wide array of sources, from ancient pictographs to Polish roosters, from skins and from skeletons, from scientific journals and breeding manuals, Darwin assembled a mass of proof--and a hypothesis about species reversion that risked his reputation anew. The Variation of Animals and Plants under Domestication is a two-volume compilation of his thorough and intensive research and the revolutionary conclusions that resulted. The first portion of his work is dedicated to a meticulous analysis of various aspects of plant and animal life, including an inventory of varieties and their physical and behavioral characteristics, investigation of the impact of a species' surrounding environment and the role that both natural and forced changes in this environment have had. Darwin then turns to a richly detailed discussion of the roles of inheritance and crossing in the development of species. A wealth of illustrations further support and enhance his findings. This fascinating, invaluable, and courageous undertaking eventually formed the foundation for our current understanding of evolution. "In science as in politics the victors tend to write the history books. As a result, the record of the past is edited, intentionally or unintentionally, so that it focuses mainly on the precursors of contemporary orthodoxy. Such a focus may accurately represent the genealogy of modern ideas, but it almost inevitably misrepresents the historical experience of their progenitors... Even the powerful, persuasive, and ultimately triumphant theory of evolution by natural selection required not only defense, but repeated buttressing and revision. Variation showed Darwin hard at work on this rearguard action, using the materials he had at hand... His information was gleaned from the observations of fanciers, breeders, and amateur naturalists, as well as from the treatises of those on the cutting edge of zoology and botany. As hindsight narrows the historical spotlight, it imposes its own sense of hierarchy on the preoccupations of the past. But Darwin was interested in all of these topics, valued all of these sources, and belonged, to a greater or lesser extent, to all of these communities."--from the Introduction. (shrink)

A new understanding of political philosophy from one of its leading thinkers What is political philosophy? What are its fundamental problems? And how should it be distinguished from moral philosophy? In this book, Charles Larmore redefines the distinctive aims of political philosophy, reformulating in this light the basis of a liberal understanding of politics. Because political life is characterized by deep and enduring conflict between rival interests and differing moral ideals, the core problems of political philosophy are the regulation (...) of conflict and the conditions under which the members of society may thus be made subject to political authority. We cannot assume that reason will lead to unanimity about these matters because individuals hold different moral convictions. Larmore therefore analyzes the concept of reasonable disagreement and investigates the ways we can adjudicate conflicts among people who reasonably disagree about the nature of the human good and the proper basis of political society. Challenging both the classical liberalism of Locke, Kant, and Mill, and more recent theories of political realism proposed by Bernard Williams and others, Larmore argues for a version of political liberalism that is centered on political legitimacy rather than on social justice, and that aims to be well suited to our times rather than universally valid. Forceful and thorough yet concise, What Is Political Philosophy? proposes a new definition of political philosophy and demonstrates the profound implications of that definition. The result is a compelling and distinctive intervention from a major political philosopher. (shrink)

The Spirit of the Laws is, without question, one of the central texts in the history of eighteenth-century thought, yet there has been no complete, scholarly English-language edition since that of Thomas Nugent, published in 1750. This lucid translation renders Montesquieu's problematic text newly accessible to a fresh generation of students, helping them to understand quite why Montesquieu was such an important figure in the early enlightenment and why The Spirit of the Laws was, for example, such an influence upon (...) those who framed the American constitution. Fully annotated, this edition focuses attention upon Montesquieu's use of sources and his text as a whole, rather than upon those opening passages towards which critical energies have traditionally been devoted, and a select bibliography and chronology are provided for those coming to Montesquieu's work for the first time.

The Tattvasaṃgraha, or Encyclopedia of Metaphysics, is the most influential and most frequently studied philosophical text from the late period of Indian Buddhism. This edition includes verses by Śāntarakṣita (c. 725-788 CE), which are clarified and expounded in the commentary of his student Kamalaśīla (c. 740-795 CE); both of these authors played crucial roles in founding the Buddhist tradition of Tibet. In the Tattvasaṃgraha, they explain, discuss and critique a vast range of views and arguments from across the whole South (...) Asian philosophical and religious spectrum. The work deals at length with ideas drawn from Buddhism, Jainism, and a variety of traditions now incorporated within Hinduism, including Mīmāṃsā, Nyāya-vaiśeṣika, and Sāṃkhya; it also includes the earliest discussion of Advaita Vedānta in any Buddhist text. The chapters selected for translation from Sanskrit and Tibetan deal with such fundamental philosophical issues as the existence or nonexistence of God and the soul; the nature of matter and of causal relationships; the connection between words and their referents; the rules of logic; the sources of our knowledge; and the compatibility of beliefs about karma with Buddhism's fundamental claim that there is no self. Introductory chapters discuss translation choices and explain the forms of argument and methods of reasoning employed by Śāntarakṣita and Kamalaśīla. (shrink)

In this book, Charles Larmore develops an account of morality, freedom, and reason that rejects the naturalistic metaphysics shaping much of modern thought. Reason, Larmore argues, is responsiveness to reasons, and reasons themselves are essentially normative in character, consisting in the way that physical and psychological facts - facts about the world of nature - count in favor of possibilities of thought and action that we can take up. Moral judgments are true or false in virtue of the moral (...) reasons there are. We need therefore a more comprehensive metaphysics that recognizes a normative dimension to reality as well. Though taking its point of departure in the analysis of moral judgment, this book branches widely into related topics such as freedom and the causal order of the world, textual interpretation, the nature of the self, self-knowledge, and the concept of duties to ourselves.

Antisemitism is fun. This essay explains why and proposes a new approach to combating it.

Kierkegaard’s ideal supports a radical form of “deep diversity,” to use Charles Taylor’s expression. It is radical because it embraces not only irreducible conceptions of the good but also incompatible ones. This is due to its paradoxical nature, which arises from its affirmation of both monism and pluralism, the One and the Many, together. It does so in at least three ways. First, in terms of the structure of the self, Kierkegaard describes his ideal as both unified (the “positive (...) third”) and plural (a “negative unity”). Second, he affirms a process which brings together unity, as implied by the linear notion of “stages”, with plurality, in the form of “spheres of existence” (aesthetic, ethical, and religious). And third, the culmination of the process implies that we should embrace both a unified dialectic (“Religiousness A”) alongside the plural remnants of the ethical/aesthetic, that is, both the infinity of the former and the finitudes of the latter. Unsurprisingly, while Kierkegaard describes those who are able to exemplify his ideal in practice as “always joyful,” he also considers the ideal to be “extremely hard, the hardest task of all.” This is why those such as Hubert L. Dreyfus are wrong to claim that it provides an experience of bliss; on the contrary, those who realize it “are always in danger.” As I shall show, one form this danger takes is that it threatens to dirty the hands of those who manage to uphold Kierkegaard’s ideal. Moreover, it does so in ways that, I claim, tend to be missed by Kierkegaard himself. Nevertheless, the danger is also essential to the creativity of his approach, and I conclude by pointing out how this creativity makes it capable of tackling one of the profoundest challenges in contemporary ethics: that arising from what just war theorists call a “supreme emergency.” .

Introduction to Hegel's thought for the student and general reader, emphasizing in particular his social and political thought and his continuing relevance to contemporary problems.

My topic is the materialist appropriation of empiricism – as conveyed in the ‘minimal credo’ nihil est in intellectu quod non fuerit in sensu (which interestingly is not just a phrase repeated from Hobbes and Locke to Diderot, but is also a medical phrase, used by Harvey, Mandeville and others). That is, canonical empiricists like Locke go out of their way to state that their project to investigate and articulate the ‘logic of ideas’ is not a scientific project: “I shall (...) not at present meddle with the Physical consideration of the Mind” (Essay, I.i.2, in Locke 1975; which Kant gets exactly wrong in his reading of Locke, in the Preface to the A edition of the first Critique). Indeed, I have suggested elsewhere, contrary to a prevalent reading of Locke, that the Essay is not the extension to the study of the mind of the methods of natural philosophy; that he is actually not the “underlabourer” of Newton and Boyle he claims politely to be in the Epistle to the Reader (Wolfe and Salter 2009, Wolfe 2010). Rather, Locke says quite directly if we pay heed to such passages, “Our Business here is not to know all things, but those which concern our Conduct” (Essay, I.i.6). There would be more to say here about what this implies for our understanding of empiricism (see Norton 1981 and Gaukroger 2005), but instead I shall focus on a different aspect of this episode: how a non-naturalistic claim which falls under what we now call epistemology (a claim about the senses as the source of knowledge) becomes an ontology – materialism. That is, how an empiricist claim could shift from being about the sources of knowledge to being about the nature of reality (and/or the mind, in which case it needs, as David Hartley saw and Denis Diderot proclaimed more overtly, an account of the relation between mental processes and the brain). (David Armstrong, for one, denied that there could be an identification between empiricism and materialism on this point: eighteenth-century history of science seems to prove him wrong: see Armstrong 1968 and 1978.) Put differently, I want to examine the shift from the logic of ideas in the seventeenth century (Locke) to an eighteenth-century focus on what kind of ‘world’ the senses give us (Condillac), to an assertion that there is only one substance in the universe (Diderot, giving a materialist cast to Spinozism), and that we need an account of the material substrate of mental life. This is neither a ‘scientific empiricism’ nor a linear developmental process from philosophical empiricism to natural science, but something else again: the unpredictable emergence of an ontology on empiricist grounds.

In these selected essays, Charles Parsons surveys the contributions of philosophers and mathematicians who shaped the philosophy of mathematics over the past century: Brouwer, Hilbert, Bernays, Weyl, Gödel, Russell, Quine, Putnam, Wang, and Tait.

This book is an examination of how the law understands human identity and the whole notion of 'human being'. On these two notions the law, usually unconsciously, builds the superstructure of 'human rights'. It explores how the law understands the concept of a human being, and hence a person who is entitled to human rights. This involves a discussion of the legal treatment of those of so-called "marginal personhood" (e.g. high functioning non-human animals; humans of limited intellectual capacity, and fetuses). (...) It also considers how we understand our identity as people, and hence how we fall into different legal categories: such as gender, religion and so on. The law makes a number of huge assumptions about some fundamental issues of human identity and authenticity - for instance that we can talk meaningfully about the entity that we call 'our self'. Until now it has rarely, if ever, identified those assumptions, let alone interrogated them. This failure has led to the law being philosophically dubious and sometimes demonstrably unfit for purpose. Its failure is increasingly hard to cover up. What should happen legally, for instance, when a disease such as dementia eliminates or radically transforms all the characteristics that most people regard as foundational to the 'self'? This book seeks to plug these gaps in the literature. (shrink)
