"Understanding Scientific Progress constitutes a potentially enormous and revolutionary advancement in philosophy of science. It deserves to be read and studied by everyone with any interest in or connection with physics or the theory of science. Maxwell cites the work of Hume, Kant, J.S. Mill, Ludwig Bolzmann, Pierre Duhem, Einstein, Henri Poincaré, C.S. Peirce, Whitehead, Russell, Carnap, A.J. Ayer, Karl Popper, Thomas Kuhn, Imre Lakatos, Paul Feyerabend, Nelson Goodman, Bas van Fraassen, and numerous others. He lauds Popper for advancing beyond (...) verificationism and Hume’s problem of induction, but faults both Kuhn and Popper for being unable to show that and how their work could lead nearer to the truth." —Dr. LLOYD EBY teaches philosophy at The George Washington University and The Catholic University of America, in Washington, DC "Maxwell's aim-oriented empiricism is in my opinion a very significant contribution to the philosophy of science. I hope that it will be widely discussed and debated." – ALAN SOKAL, Professor of Physics, New York University "Maxwell takes up the philosophical challenge of how natural science makes progress and provides a superb treatment of the problem in terms of the contrast between traditional conceptions and his own scientifically-informed theory—aim-oriented empiricism. This clear and rigorously-argued work deserves the attention of scientists and philosophers alike, especially those who believe that it is the accumulation of knowledge and technology that answers the question."—LEEMON McHENRY, California State University, Northridge "Maxwell has distilled the finest essence of the scientific enterprise. Science is about making the world a better place. Sometimes science loses its way. The future depends on scientists doing the right things for the right reasons. Maxwell's Aim-Oriented Empiricism is a map to put science back on the right track."—TIMOTHY McGETTIGAN, Professor of Sociology, Colorado State University - Pueblo "Maxwell has a great deal to offer with these important ideas, and deserves to be much more widely recognised than he is. Readers with a background in philosophy of science will appreciate the rigour and thoroughness of his argument, while more general readers will find his aim-oriented rationality a promising way forward in terms of a future sustainable and wise social order."—David Lorimer, Paradigm Explorer, 2017/2 "This is a book about the very core problems of the philosophy of science. The idea of replacing Standard Empiricism with Aim-Oriented Empiricism is understood by Maxwell as the key to the solution of these central problems. Maxwell handles his main tool masterfully, producing a fascinating and important reading to his colleagues in the field. However, Nicholas Maxwell is much more than just a philosopher of science. In the closing part of the book he lets the reader know about his deep concern and possible solutions of the biggest problems humanity is facing."—Professor PEETER MŰŰREPP, Tallinn University of Technology, Estonia “For many years, Maxwell has been arguing that fundamental philosophical problems about scientific progress, especially the problem of induction, cannot be solved granted standard empiricism (SE), a doctrine which, he thinks, most scientists and philosophers of science take for granted. A key tenet of SE is that no permanent thesis about the world can be accepted as a part of scientific knowledge independent of evidence. For a number of reasons, Maxwell argues, we need to adopt a rather different conception of science which he calls aim-oriented empiricism (AOE). This holds that we need to construe physics as accepting, as a part of theoretical scientific knowledge, a hierarchy of metaphysical theses about the comprehensibility and knowability of the universe, which become increasingly insubstantial as we go up the hierarchy. In his book “Understanding Scientific Progress: Aim-Oriented Empiricism”, Maxwell gives a concise and excellent illustration of this view and the arguments supporting it… Maxwell’s book is a potentially important contribution to our understanding of scientific progress and philosophy of science more generally. Maybe it is the time for scientists and philosophers to acknowledge that science has to make metaphysical assumptions concerning the knowability and comprehensibility of the universe. Fundamental philosophical problems about scientific progress, which cannot be solved granted SE, may be solved granted AOE.” Professor SHAN GAO, Shanxi University, China . (shrink)

The possibility of justified true belief without knowledge is normally motivated by informally classified examples. This paper shows that it can also be motivated more formally, by a natural class of epistemic models in which both knowledge and justified belief are represented. The models involve a distinction between appearance and reality. Gettier cases arise because the agent's ignorance increases as the gap between appearance and reality widens. The models also exhibit an epistemic asymmetry between good and bad cases that sceptics (...) seem to ignore or deny. (shrink)

The paper clarifies and defends the orthodox view that counterfactual conditionals with impossible antecedents are vacuously true against recent criticisms. It argues that apparent counterexamples to orthodoxy result from uncritical reliance on a fallible heuristic used in the processing of conditionals. A comparison is developed between such counterpossibles and vacuously true universal generalizations.

Carruthers argues that knowledge of our own propositional attitudes is achieved by the same mechanism used to attain knowledge of other people's minds. This seems incompatible with "privileged access"---the idea that we have more reliable beliefs about our own mental states, regardless of the mechanism. At one point Carruthers seems to suggest he may be able to maintain privileged access, because we have additional sensory information in our own case. We raise a number of worries for this suggestion, concluding that (...) Carruthers's new theory cannot clearly preserve the superior reliability of our beliefs about our own attitudes. (shrink)

The chapter argues that a model‐building methodology like that widespread in contemporary natural and social science already plays a significant role in philosophy. One neglected form of progress in philosophy over the past fifty years has been the development of better and better formal models of significant phenomena. Examples are given from both philosophy of language and epistemology. Philosophy can do still better in the future by applying model‐building methods more systematically and self‐consciously, with consequent readjustments to its methodology. Although (...) it is neither likely nor desirable for model‐building to become the sole or even main philosophical method, its use enhances the power and reliability of philosophical thinking.

Many advocates of non-classical logic for reasons external to mathematics claim that their proposed revisions are consistent with the use of classical logic within pure mathematics. Doubts are raised about such claims, concerning the applicability of pure mathematics to natural and social science. -/- .

There is a constant temptation in philosophy to postulate a realm of phenomena in which nothing is hidden from us. Rene Descartes thought that one's own mind is such a realm. Ludwig Wittgenstein' enlarged the realm to everything that is of interest to philosophy. That they explained this special feature in very different ways hardly needs to be said; what is remarkable is their agreement on our possession of a cognitive home in which everything lies open to our view. Much (...) of our thinking – for example, in the physical sciences – must operate outside this home, in alien circumstances. The claim is that not all our thinking could be like that. (shrink)

Philosophers have spent a great deal of time debating whether intransitive preferences can be rational. I present a risky decision that poses a challenge for the defender of intransitivity. The defender of intransitivity faces a trilemma and must either: (i) reject the rationality of intransitive preferences, (ii) deny State-wise Dominance, or (iii) accept the bizarre verdict that you can be required to pay to relabel the tickets of a fair lottery. If we take the first horn, then we have a (...) synchronic refutation of intransitivity, an improvement on widely criticized diachronic arguments. I sketch possible responses that may rescue intransitivity and argue that each response is possible but generates an explanatory debt. I conclude by showing how the challenge here clarifies the foundations of decision theory without transitivity, conditional on some explanatory debt being payable. (shrink)

The paper explains how Gettier’s conclusion can be reached on general theoretical grounds within the framework of epistemic logic, without reliance on thought experiments. It extends the argument to permissive conceptions of justification that invalidate principles of multi-premise closure and require neighbourhood semantics rather than semantics of a more standard type. The paper concludes by recommending a robust methodology that aims at convergence in results between thought experimentation and more formal methods. It also warns against conjunctive definitions as sharing several (...) of the drawbacks of disjunctive definitions. (shrink)

Timothy Chappell develops a picture of what philosophical ethics can be like, once set aside from conventional moral theory. His question is 'How are we to know what to do?', and the answer he defends is 'By developing our moral imaginations'--a key part of human excellence, which plays many roles in our practical and evaluative lives.

Timothy Chappell’s new translation of the Theaetetus is presented here in short sections of text, each preceded by a summary of the argument and followed by his philosophical commentary on it. Introductory remarks discuss Plato and his works, his use of dialogue, the structure of the Theaetetus, and alternative interpretations of the work as a whole. A glossary and bibliography are provided.

The ArgumentHistorians of science naturally tend to express interest in other forms of intellectual activity only when these intersect with science. This tendncy has produced a number of enlightening studies of what happens when science and (for instance) law or theology come into contact, but little by way of how science enters into the calculations and social status of such forms of knowledge after the conjuction has passed. Recent work in the sociology of professions, in contrast, has focused attention precisely (...) on those moments when the expert knowledge produced by different group doesnotoverlap. This has been the contribution of Andrew Abbortt's theory of “jurisdictional boundaries” between competing professions. The case of Victorian actuaries who worked hard to maintain unique intellectual claims in the competitive life insurance industry while maintainiing strong social connections and overlaps in knowledge with organized science, challenges the way both historians of science and sociologists of professions view contending knowledge claims. By observing what motivated actuaries to forge an alliance with men of science in the 1820s, then tracing their gradual recognition of a need to distance themselves from certain of the “scientific” values that had earlier informed their collective identity, it is possible to make sense of connections as well as disconnections between science and other forms of knowledge. A history of quantification from the actuaries' perspective, in other words, allows us to view science bothasandincontext. (shrink)

Scepticism is a disease in which healthy mental processes run pathologically unchecked. Our cognitive immunity system, designed to protect our conception of the world from harmful errors, turns destructively on that conception itself. Since we have false beliefs, we benefit from the ability to detect our mistakes; removing our errors tends to do us good. Our cognitive immunity system should be able to destroy bad old beliefs, not just prevent the influx of new ones. But that ability sometimes becomes indiscriminate, (...) and destroys good beliefs too. That can happen in several ways. I start by considering two of them. (shrink)

We draw a distinction between the Aharonov–Bohm phase shift and the Aharonov–Bohm effect. Although the Aharonov–Bohm phase shift occurring when an electron beam passes around a magnetic solenoid is well-verified experimentally, it is not clear whether this phase shift occurs because of classical forces or because of a topological effect occurring in the absence of classical forces as claimed by Aharonov and Bohm. The mathematics of the Schroedinger equation itself does not reveal the physical basis for the effect. However, the (...) experimentally observed Aharonov–Bohm phase shift is of the same form as the shift observed due to electrostatic forces for which the consensus view accepts the role of the classical forces. The Aharonov–Bohm phase shift may well arise from classical electromagnetic forces which are simply more subtle in the magnetic case since they involve relativistic effects of the order v 2 /c 2 . Here we first review the experimentally observable differences between phenomena arising from classical forces and phenomena arising from the quantum topological effect suggested by Aharonov and Bohm. Second we point out that most discussions of the classical electromagnetic forces involved when a charged particle passes a solenoid are inaccurate because they omit the Faraday induction terms. The subtleties of the relativisitic v 2 /c 2 classical electromagnetic forces between a point charge and a solenoid have been explored by Coleman and Van Vleck in their analysis of the Shockley–James paradox; indeed, we point out that an analysis exactly parallel to that of Coleman and Van Vleck suggests that the Aharonov–Bohm phase shift is actually due to classical electromagnetic forces. Finally we note that electromagnetic velocity fields penetrate even excellent conductors in a form which is unfamiliar to many physicists. An ohmic conductor surrounding a solenoid does not screen out the magnetic field of the passing charge, but rather the time-integral of the magnetic field is an invariant; this time integral is precisely what is involved in the classical explanation of the Aharonov–Bohm phase shift. Thus the persistence of the Aharonov–Bohm phase shift when the solenoid is surrounded by a conductor does not exclude a classical force-based explanation for the phase shift. At present there is no experimental evidence for the Aharonov–Bohm effect. (shrink)

In this article I further Adriana Cavarero and Nidesh Lawtoo’s discussion of “mimetic inclination” to consider the way a person can be known in their uniqueness. Cavarero says that we receive a sense of the uniqueness of another by relating their narrative. I suggest that this also reveals a sense of the uniqueness of the one narrating, and that this can be understood as a practice of care. This narration is, as a consequence, distinct from representation (which itself is distinct (...) from mimesis) and is better described as apprehension. By drawing on Toni Morrison’s Beloved and Christina Sharpe’s In the Wake: On Blackness and Being, I detail a primary form of care connected to apprehension that is engendered by what Sharpe calls “the weather of antiblackness”. Morrison both details this form of care in Beloved and practises it herself in her storytelling. This expands feminist analyses of vulnerability, providing critical resources for rethinking existence apart from its colonial and patriarchal articulation. (shrink)

After some reflections on style in contemporary anglophone philosophy, I dig a little deeper, and explore what that style is a symptom of — which I suggest is a kind of blindness to the importance of the second-personal in ethics. I develop the notion of the second-personal with reference to Levinas and Darwall; and I show some of the explanatory potential of that notion by looking again at divine-command ethics.

This article seeks to critically question the internal logic and coherence of ‘anti-doping’ through the case study of advantage-seeking practices in the sport of Brazilian Jui-Jitsu (BJJ). We provide an analysis of the recent controversy between high-profile fighters Gordon Ryan and Nicky Rod involving the relative morality of image and performance enhancing drug (IPED) use compared with ‘greasing’, whereby BJJ athletes apply substances, such as oil or lubricants, to the body to make it harder for opponents to establish a grip (...) or maintain control during grappling exchanges. We employ this case study to highlight the impasse between the World Anti-Doping Agency’s (WADA) ethical foundation of the ‘spirit of sport’ and the anti-doping industry’s ‘anti-policy’ stance. We then query why a host of non-chemical advantage-seeking practices are normalised and overlooked within the rigid and constrictive systems. Ultimately, we characterise WADA as a myopic compliance system that stifles moral debate around advantage-seeking in sport and is hamstrung by an ethical discord between anti-policy and the neo-Aristotelian ideal of the spirit of sport. We close with a call for a holistic ethical understanding of advantage-seeking in sport and the need to encourage stakeholders to ‘think institutionally’ in order to establish a malleable and reactive response to doping.

In the face of climate change, moral motivation is central: why should individuals feel compelled to act to combat this problem? Justice-based responses miss two morally salient issues: that the key ethical relationship is between us and the environment, and there is something in it for us to act to aid our environment. In support of this thesis there are two seemingly disparate sources: Pope Francis’ encyclical Laudato Si and the early Marx’s account of human essence as species-being. Francis argues (...) we must see nature as an “other” with whom we have a relationship, rather than dominating nature. Marx considers how we currently interact with “others,” and the harms these interactions cause to us. In both contexts, we harm our environment by not acting to meet its needs, and harm ourselves by making it less likely to develop ourselves as more fully human persons. It is the avoidance of these harms that can motivate us to act against climate change. (shrink)

It has been suggested that damage to anterior regions of the left hemisphere results in a dissociation in the perception and lexical activation of past-tense forms. Specifically, in a lexical-decision task in which past-tense primes immediately precede present-tense targets, such patients demonstrate significant priming for irregular verbs (spoke–speak), but, unlike control participants, fail to do so for regular verbs (looked–look). Here, this behavioral dissociation was first confirmed in a group of eleven patients with damage to the pars opercularis (BA 44) (...) and pars triangularis (BA 45) of the left inferior frontal gyrus (i.e., Broca's area). Two conditions containing word-onset orthographic–phonological overlap (bead–bee, barge–bar) demonstrated that the disrupted regular-verb priming was accompanied by, and covaried with, disrupted ortho-phonological priming, regardless of whether prime stimuli contained the regular inflectional rhyme pattern. Further, the dissociation between impaired regular-verb and preserved irregular-verb priming was shown to be continuous rather than categorical; priming for weak-irregular verbs (spent–spend) was intermediate in size between that of regular verbs and strong verbs. Such continuous dissociations grounded in ortho-phonological relationships between present- and past-tense forms are predicted by single-system, connectionist approaches to inflectional morphology and not predicted by current dual-system, rule-based models. Event-related potential data demonstrated that N400 priming effects were intact for both regular and irregular verbs, suggesting that the absence of significant regular-verb priming in the response time data did not result from a disruption of lexical access, and may have stemmed instead from post-lexical events such as covert articulation, segmentation strategies, and/or cognitive control.

The paper defends the infallibilist account of evidential support in Knowledge and its limits from Jessica Brown’s objections in her book Fallibilism: Evidence and Knowledge. By the standards of abductive methodology, Brown’s arguments are ineffective because she offers no developed alternative account of evidential support. Most of her objections apply to the standard probabilistic structure of my account; they are not specific to its distinctively knowledge-first features. Brown’s objection from ‘infelicity data’ is analogous to one from such data to standard (...) accounts of deductive validity as truth-preservation. Contrary to Brown’s assumption, my use of excusability in discussion of sceptical scenarios involves no attempt to give it a precise conceptual analysis. (shrink)

It is no accident that in his Ethics textbook, John Dewey discussed marriage and family, population growth, and managing the social sphere together, albeit briefly. In early- and mid-twentieth century intellectual circles, especially in the United States, the issue of maintaining a healthy "family stock" was not without its controversy. To some theorists, the notion of "social control" alluded to various forms of "population control," and beyond more "traditional" state laws restricting interracial marriage, social policies emerged advocating various forms of (...) eugenics. Some of these policies manifested in state laws. Indiana passed the first eugenic sterilization law in 1907, followed by California in 1909. By the .. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Virtues of the Will: The Transformation of Ethics in the Late Thirteenth Century by Bonnie KentTimothy B. NooneBonnie Kent. Virtues of the Will: The Transformation of Ethics in the Late Thirteenth Century. Washington, D.C.: The Catholic University of America Press, 1995. Pp. viii + 270. Cloth, $44.95.In this admirably written study, Bonnie Kent presents researchers on medieval philosophy with a survey of moral psychology during the crucial period (...) between the death of Thomas Aquinas and the summit of Duns Scotus’s career in the first decade of the fourteenth century. Although there have been many studies of particular issues in particular thinkers during this period and a generous presentation of texts with commentary by the great Dom Lottin (Psychologie et morale aux XIIe et XIIIe siècles, 7 vols. Louvain, 1942–1954), there has not been any lengthy study to date devoted to the period of the late thirteenth century that focused on moral psychology and the will. Simply in drawing attention to this period in the history of moral psychology, Professor Kent has made a tremendous contribution to the study of medieval philosophy, since she has rendered accessible authors that are more often than not neglected and overlooked. Kent, in fact, attempts something more: she places her study in the framework of the general historiography of Scholastic thought and the more recent interest in medieval ethics prompted by those championing virtue ethics.In order to highlight the distinguishing features of recent studies on medieval ethical thought, Kent reviews the established interpretation of philosophy in the thirteenth century. In the opening chapter, entitled “Heroes and Histories,” she points out the features common to the scholarly approaches of Gilson, Van Steenberghen, and even Copleston: (1) a prominent role is assigned to schools and movements, especially Aristotelianism and Augustinianism; (2) metaphysics and epistemology are the primary objects of study along with the relation between philosophy and theology; and (3) the Thomistic point of view is the organizing principle for telling the drama of the period. The last feature means that the history of the period is fundamentally told as streams of influence leading to Aquinas, followed by the golden age of Aquinas and his contemporaries and succeeded by a gradual decline after Aquinas, leading to the demise of Scholastic thought. In the context of the established historiography, accordingly, the approach of Alasdair MacIntyre represents a restatement of the common view, but one more radical in form. Instead of being merely different schools or movements, Augustinianism and Aristotelianism are different worldviews with their own paradigmatic conceptions of rationality, each of which is subsumed into the higher synthesis of Thomism. According to MacIntyre, the passage to modernity is begun by Scotus whose innovative theses in moral psychology and ethics are considered revolutionary.Kent’s stated aim is to challenge the “standard story” found in Gilson and others as well as its revised version in MacIntyre’s writings by providing a detailed study of the [End Page 462] period just prior to Scotus and establishing precisely how revolutionary Scotus’s teachings were when compared to his immediate predecessors. She accomplishes this aim masterfully in a series of chapters dedicated to the sources of medieval thought and elements of moral psychology. Beginning with late thirteenth-century thinkers’ attitude toward Aristotle in her second chapter, she shows in considerable detail that there is little evidence for any serious anti-Aristotelianism in the vast majority of late thirteenth-century authors. Indeed, the posture of these thinkers was to separate Aristotle from radical Aristotelianism and Thomism in order to claim that ancient wisdom was on the side of Christian ethics and psychology. The only exception that Kent finds to this widespread attitude is in the writings of Peter John Olivi whose hostility to pagan philosophy is clearly evident.The focus in the next chapter is on ethical voluntarism, a position characterized by the endorsement of the superiority of will over reason, the claim that human freedom resides primarily in the faculty of the will, that the will can act contrary to reason’s judgment, and that the will, not the intellect, commands the lower powers of the soul. In detailing the advent of... (shrink)
