According to an orthodox view, the capacity for conscious experience (sentience) is relevant to the distribution of moral status and value. However, physicalism about consciousness might threaten the normative relevance of sentience. According to the indeterminacy argument, sentience is metaphysically indeterminate while indeterminacy of sentience is incompatible with its normative relevance. According to the introspective argument (by François Kammerer), the unreliability of our conscious introspection undercuts the justification for belief in the normative relevance of consciousness. I defend the normative relevance (...) of sentience against these objections. First, I demonstrate that physicalists only have to concede a limited amount of indeterminacy of sentience. This moderate indeterminacy is in harmony with the role of sentience in determining moral status. Second, I argue that physicalism gives us no reason to expect that introspection is unreliable with respect to the normative relevance of consciousness. (shrink)

Which artificial intelligence (AI) systems are agents? To answer this question, I propose a multidimensional account of agency. According to this account, a system's agency profile is jointly determined by its level of goal-directedness and autonomy as well as is abilities for directly impacting the surrounding world, long-term planning and acting for reasons. Rooted in extant theories of agency, this account enables fine-grained, nuanced comparative characterizations of artificial agency. I show that this account has multiple important virtues and is more (...) informative than alternatives. More speculatively, it may help to illuminate two important emerging questions in AI ethics: 1. Can agency contribute to the moral status of non-human beings, and how? 2. When and why might AI systems exhibit power-seeking behaviour and does this pose an existential risk to humanity? (shrink)

Hybrid expressivists claim to solve the Frege-Geach problem by offloading the explanation of the logico-semantic properties of moral sentences onto beliefs that are components of hybrid states they express. We argue that this strategy is undermined by one of hybrid expressivism’s own commitments: that the truth of the belief-component is neither necessary nor sufficient for the truth of the hybrid state it composes. We articulate a new approach. Instead of explaining head-on what it is for, say, a pair of moral (...) sentences to be inconsistent, expressivists should “sidestep” and explain what it is _to think that_ a pair of moral sentences is inconsistent. To think so is to think they cannot both be true – a modal notion. Since expressivists have given accounts of such modals, we illustrate how sentences like ‘“lying is wrong” and “lying is not wrong” are inconsistent’ express sensible – and rationally compelling – states of mind.

Which animals have conscious experiences? Many different, diverse and unrelated behaviors and cognitive capacities have been proposed as tests of the presence of consciousness in an animal. It is unclear which of these tests, if any, are valid. To remedy this problem, I develop a list consisting of eight desiderata which can be used to assess putative tests of animal consciousness. These desiderata are based either on detailed analogies between consciousness-linked human behavior and non-human behavior, on theories of consciousness or (...) on methods from human consciousness science. If a test or set of tests satisfies more of these desiderata, passing it provides stronger evidence of consciousness. Moreover, one can design future tests of animal consciousness with the intention of satisfying these desiderata to ensure their evidential strength. (shrink)

Numerous authors have expressed concern that advanced artificial intelligence (AI) poses an existential risk to humanity. These authors argue that we might build AI which is vastly intellectually superior to humans (a ‘superintelligence’), and which optimizes for goals that strike us as morally bad, or even irrational. Thus, this argument assumes that a superintelligence might have morally bad goals. However, according to some views, a superintelligence necessarily has morally adequate goals. This might be the case either because abilities for moral (...) reasoning and intelligence mutually depend on each other, or because moral realism and moral internalism are true. I argue that the former argument misconstrues the view that intelligence and goals are independent, and that the latter argument misunderstands the implications of moral internalism. Moreover, the current state of AI research provides additional reasons to think that a superintelligence could have bad goals. (shrink)

Sensorimotor enactivism is the view that the content and the sensory modality of perceptual experience are determined by implicit knowledge of lawful regularities between bodily movements and patterns of sensory stimulation. A proponent of the explanatory argument for sensorimotor enactivism holds that this view is able to provide an intelligible explanation for why certain material realizers give rise to certain perceptual experiences, while rival accounts cannot close this “explanatory gap”. However, I argue that the notion of the “material realizer” of (...) perceptual experience is ambiguous. On a narrow construal, the explanatory gap cannot be bridged, not even by enactivism. On a wide construal, enactivism gets a grip on the explanatory gap, but to the same extent do established theories of consciousness. Thus, on both horns of the dilemma, the explanatory power of enactivism is not superior to more traditional theories of conscious experience. (shrink)

Scientific method interests the linguist not only as it interests every scientific worker, but also in a special way, because the scientist, as part of his method, utters certain very peculiar speech-forms. The linguist naturally divides scientific activity into two phases: the scientist performs “handling” actions and utters speech. The speech-forms which the scientist utters are peculiar both in their form and in their effect upon hearers.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:What's so Important about Music Education?Leonard TanJ. Scott Goble, What's so Important about Music Education? (New York, NY: Routledge, 2010)In What's so Important about Music Education, J. Scott Goble proposes a new philosophical foundation for music education in the United States based on the theory of semiotics by American pragmatist Charles Sanders Peirce. Following a brief summary, I will note several merits in Goble's book before sketching (...) four recommendations for future editions.In Chapter One, Goble notes how the inclusion of non-Western musics in the public schools as espoused in the 1967 Tanglewood Declaration has raised two crucial questions: "Whose music should be included in the curriculum?" and "What is the role or social importance of public school music education in the United States as a postmodern society?" Noting that music education was established in the United States during the modern era, and that the Tanglewood Declaration did not account for vast differences in beliefs about music, Goble argues that there is a need to establish a new philosophical foundation that can accommodate the varied beliefs and practices of diverse cultural groups in postmodern United States.In Chapter Two, Goble sketches and critiques five cultural anthropologists. Of the five, he singles out Clifford Geertz's conception of culture as "semiotic [End Page 201] webs" (p. 20) as the conceptual foundation that is appropriate for this study. He then links Geertz's notion of culture to the semiotic theory of C. S. Peirce which is to become the theoretical underpinning of the book. Subsequently, he unpacks many key Peircian themes: human conceptions are maintained not individually but collectively in cultural groups, provisional truth (as opposed to absolute Truth) is relative and dependent on conceptions of communities, and the scientific method is the sole mode of inquiry by which people in communities may use to satisfy their doubts to formulate beliefs. Most importantly, Goble expounds the "pragmatic maxim" that since humans live in communities united by common beliefs, "the 'clear' meaning of an idea held by a member of the community will almost inevitably stem from the beliefs—or ways of understanding—held by members of that community" (p. 30). Goble concludes the chapter by presenting the Peircian semiotic system of cognition which posits that a "sign" is conceptualized in a triadic relationship: the Sign or "Firstness," the Object or "Secondness," and the Interpretant or "Thirdness" (p. 33).In Chapter Three, Goble considers how music is a sign based on the theoretical framework laid in Chapter Two. Drawing on the work of ethnomusicologists, anthropologists, psychiatrists, and a neuroscientist, he formulates a Peircian pragmatic approach to musical practices which posits that "the musical practices of different cultural communities represent a diverse cluster of community-specific ritualized behaviors involving sound" (p. 252). Furthermore, each of the musical practices "serves those persons who meaningfully participate in it as a means of psychophysiological, psychosocial, and/or sociopolitical equilibration relative to the worldview—or ordered conception of Reality—they tacitly share" (p. 252). For Goble, this pragmatist conception of musical practices is neither ethnocentric, universalist, nor relativist, and can serve as a conceptual framework for all diverse musical practices in postmodern United States.With the Peircian pragmatic conception in mind, Goble examines historical factors that contributed to current conceptions of music in the United States in Chapter Four. He laments that as a result of European Enlightenment and three socio-political phenomena in the United States (the separation of church and state, promotion of no other worldview than democracy, and adoption of democratic capitalism), music is no longer pragmatically oriented but trivialized and pursued by self-serving musicians.In Chapter Five, Goble traces the philosophical justifications for music education throughout the history of the United States. While the sign "musical practice" was conceptualized as "worship" in colonial America, the sign "music" was conceived as "art" during the age of Enlightenment, and as "product" during the age of science and technology. Noting that Bennett Reimer's music education as aesthetic education is limited in its Western focus on music as works [End Page 202] of artistic objects, Goble aligns his Peircian conception along praxial lines—in particular, with...

Jus post Bellum is, like Jus ad Bellum and Jus in Bello, a part of just war theory. Jus post Bellum is distinguished from the other parts of just war theory by being primarily concerned with the principles necessary for securing a just and lasting peace after the end of a war. Traditionally, jus post bellum has focused primarily on three goals: [1] compensating those who have been the victims of unjust aggression, while respecting the rights of the aggressors, [2] (...) punishing and rehabilitating those guilty of war crimes and other violations of the principles of Jus ad Bellum and Jus in Bello and [3] developing measures that will prevent future war and violence (Orend 2000 and May 2012). In this chapter, I outline an account of political forgiveness and explain the role that political forgiveness can have in promoting the goals of jus post bellum. My conception of political forgiveness requires some unpacking. Let me begin with individual forgiveness, which I understand along familiar Butlerian lines as the renunciation of resentment (Butler, Sermon IX in McNaughton 2017: 75-83), though with a bit of a twist. More exactly, ● An individual, I, forgives J for doing F if and only if I renounces all her own warrant for resenting J for doing F. Resentment is a judgment-sensitive attitude, and, therefore, it tends to track judgments concerning its warrant (Scanlon 1998: 20 and Smith 2015). In cases of perfect forgiveness, I’s renunciation causes her to cease feeling resentment toward J for doing F, though, of course, less perfect cases are possible. I reject the idea that there is a sharp discontinuity between individual and political forgiveness, a position argued for by, e.g., Peter Digeser (1998 and 2001). By contrast, I understand political forgiveness as the renunciation of resentment by the relevant political body in question. With greater precision, ● A sovereign political body, P, forgives J for doing F if and only if P renounces all warrant that its citizens have for resenting, as part of their public lives, J for doing F. A little more explanation is in order. Sovereign political bodies, such as national governments, claim degrees of control over the lives of their citizens, in both their public and their private aspects, though the claims with respect to the former tend to be considerably more expansive than the claims with respect to the latter. I assume here that, at least in the case of legitimate governments, these claims of control are often valid. Such governments may reasonably renounce certain grounds for motivating action in the public sphere. For example, governments may renounce all warrant that its citizens have, as part of their public lives, for hating members of marginalized groups. In practice, this means that, while citizens might continue to act in their private lives out of hatred for members of these groups, their appeal to this hatred is seen by the state as irrelevant to matters of law and public policy as well as being wholly out-of-place in public discourse. Political forgiveness toward J for doing F, as I understand it, involves an analogous rejection of resentment, on the part of citizens in their public lives, toward J for doing F. I turn now to the matter of how political forgiveness supports securing a just and lasting peace between former belligerents. With respect to the first goal of jus post bellum, political forgiveness helps to balance compensation for victims and respect for the rights of defeated aggressors by countering the all-too-human tendency to overvalue harms done to oneself and to members of one’s group. As regards the second goal, political forgiveness plays a similar role but also provides a model for rehabilitation by exemplifying among the victorious the behavior to be emulated by the vanquished. Finally, political forgiveness promotes the third goal of jus post bellum by providing a space for nations to meet as moral equals rather than allowing one nation to have the moral high ground over the other. None of this, of course, means that political forgiveness should be unearned or that it should be confused with condonation (Kolnai 1973 and Pettigrove 2004). However, the question of what is required to put oneself in a position to be forgiven as part of jus post bellum is a matter that goes beyond the scope of this chapter. (shrink)

Recent debates between proponents of the modern evolutionary synthesis (the standard model in evolutionary biology) and those of a possible extended synthesis are a good example of the fascinating tangle among empirical, theoretical, and conceptual or philosophical matters that is the practice of evolutionary biology. In this essay, we briefly discuss two case studies from this debate, highlighting the relevance of philosophical thinking to evolutionary biologists in the hope of spurring further constructive cross-pollination between the two fields.

Philosophy has been a public endeavor since its origins in ancient Greece, India, and China. However, recent years have seen the development of a new type of public philosophy conducted by both academics and non- professionals. The new public philosophy manifests itself in a range of modalities, from the publication of magazines and books for the general public to a variety of initiatives that exploit the power and flexibility of social networks and new media. In this paper we examine the (...) phenomenon of public philosophy in its several facets, and investigate whether and in what sense it is itself a mix of philosophical practice and teaching. We conclude with a number of suggestions to academic colleagues on why and how to foster further growth of public philosophy for the benefit of society at large and of the discipline itself.

: New genetic technologies continue to emerge that allow us to control the genetic endowment of future children. Increasingly the claim is made that it is morally "irresponsible" for parents to fail to use such technologies when they know their possible children are at risk for a serious genetic disorder. We believe such charges are often unwarranted. Our goal in this article is to offer a careful conceptual analysis of the language of irresponsibility in an effort to encourage more care (...) in its use. Two of our more important sub-claims are: A fair judgment of genetic irresponsibility necessarily requires a thick background description of the specific reproductive choice; and there is no necessary connection between an act's being morally wrong and its being irresponsible. These are distinct judgments requiring distinct justifications. (shrink)

Ned Markosian has recently defended a new theory of composition, which he calls regionalism : some material objects xx compose something if and only if there is a material object located at the fusion of the locations of xx. Markosian argues that regionalism follows from what he calls the subregion theory of parthood. Korman and Carmichael agree. We provide countermodels to show that regionalism does not follow from, even together with fourteen potentially implicit background principles. We then show that regionalism (...) does follow from five of those background principles together with and two additional principles connecting parthood and location, which we call and. While the additional principles are not uncontroversial, our conjecture is that many will find them attractive. We conclude by mentioning that fills a previously unnoticed gap in the formal theory of location presented in Parsons. (shrink)

The paper, Some Indigenous Solutions to African Environmental Problems: An Appraisal, is written to examine the relevance of African Environmental Philosophies to addressing African environmental problems. African environmental problems include: water pollution, air pollution, land pollution, climate change, flood and many more. Researchers have shown that these problems are caused by phenomena like coal mining, nuclear waste, deforestation, overfishing, wars, etc. It is a known fact that attempts have been made over the years to resolve these problems, with pockets of (...) successes, yet more needs to be done. Nigeria’s Niger Delta Development Commission, Kenya’s Bio-safty Act 2009, The National Environment Policy of Ghana, Oil Pipeline Act 2004, Nuclear Safety and Radiation Protection Act 2004 are a good example of such attempts with pockets of successes and challenges. This work uses the methods of rational speculation and critical analysis to examine aboriginal approaches to resolving African environmental challenges as recorded in Mark Omorovie Ikeke’s Philosophical Consciences, Caroline N. Mbonu’s Ecospiritualism, Thaddeus Metz’s Model Relationalism, and Chimakonam Jonathan Okeke’s Ohanifism. This work charged African environmental policymakers, Lecturers, and Students with the responsibility to understand and apply the theoretical foundation for sustainable living as recorded in the above philosophies. This is the time when Africans must use indigenous African methods and principles to proffer solutions to African environmental problems. (shrink)

Building on recent formal work by Aleks Knoks, we explore how the idea that certain epistemic norms may be indeterminate could be implemented in a default logic.

Bioethicists appearing in the media have been accused of "shooting from the hip" (Rachels, 1991). The criticism is sometimes justified. We identify some reasons our interactions with the press can have bad results and suggest remedies. In particular we describe a target (fostering better public dialogue), obstacles to hitting the target (such as intrinsic and accidental defects in our knowledge) and suggest some practical ways to surmont those obstacles (including seeking out ways to write or speak at length, rather than (...) in sound bites). We make use of our own research into the way journalists quote bioethicists. We end by suggesting that the profession as a whole look into this question more fully. (shrink)

Recently, a number of cases have been proposed which seem to show that – contrary to widely held opinion – a subject can inferentially come to know some proposition p from an inference which relies on a false belief q which is essential. The standard response to these cases is to insist that there is really an additional true belief in the vicinity, making the false belief inessential. I present a new kind of case suggesting that a subject can inferentially (...) come to know a proposition from an essential false belief where no truth in the vicinity seems to be present. (shrink)

The UN Convention against Torture defines torture as “any act by which severe pain or suffering, whether physical or mental, is intentionally inflicted on a person” by someone acting in an official capacity for purposes such as obtaining a confession or punishing or intimidating that person.1 It is unethical for healthcare professionals to participate in torture, including any use of medical knowledge or skill to facilitate torture or allow it to continue, or to be present during torture.2-7 Yet medical participation (...) in torture has taken place throughout the world and was a prominent feature of the US interrogation practice in military and Central Intelligence Agency (CIA) detention facilities in the years after the attacks of 11 September 2001.8-11 Little attention has been paid, however, to how a regime of torture affects the ability of health professionals to meet their obligations regarding routine clinical care for detainees. -/- The 2016 release of previously classified portions of guideline from the CIA regarding medical practice in its secret detention facilities sheds light on that question. These show that the CIA instructed healthcare professions to subordinate their fundamental ethical obligations regarding professional standards of care to further the objectives of the torturers.

The paper Ethical Issues in Arms Technology is written to highlight and explain some ethical issues in arms production. These issues include the act of innovation; issues with weapons of mass destruction, the issue of privacy; humanizing arms technology, artificial intelligence – military killer robots, etc. The paper advocated for a critical evaluation of the structural and potential nature of arms before they are mass-produced. We need to ask and address all possible moral questions at research level rather than wait (...) for the technologies to be developed and sent to the market place. The research employed the methods of rational speculation, critical analysis, evaluation, and prescription to call for ethical assessment of all arms before they are made available to the markets. This paper advocate for a stop on the production of any arms technology that will destroy the relationship between man and his environment. Scientists and arms researchers should give ethics a stool the heart of their research and production. Before production, every arms technology template must be ethically worthy before consideration is made to mass-produce them. With this new development, we shall eradicate the production of non-human value-adding arms from our world. Humanity does not need everything. We should accept and produce only what we need.

Theoretical arguments and empirical investigations indicate that a high proportion of published findings do not replicate and are likely false. The current position paper provides a broad perspective on scientific error, which may lead to replication failures. This broad perspective focuses on reform history and on opportunities for future reform. We organize our perspective along four main themes: institutional reform, methodological reform, statistical reform and publishing reform. For each theme, we illustrate potential errors by narrating the story of a fictional (...) researcher during the research cycle. We discuss future opportunities for reform. The resulting agenda provides a resource to usher in an era that is marked by a research culture that is less error-prone and a scientific publication landscape with fewer spurious findings.

Anarchism is by far the least broadly understood ideology and the least studied academically. Though highly influential, both historically and in terms of recent social movements, anarchism is regularly dismissed. Anarchism: A Conceptual Approach is a welcome addition to this growing field, which is widely debated but poorly understood. Occupying a distinctive position in the study of anarchist ideology, this volume, authored by a handpicked group of established and rising scholars, investigates how anarchists often seek to sharpen their message and (...) struggle to determine what ideas and actions are central to their identity. Moving beyond defining anarchism as simply an ideology or political theory, this book examines the meanings of its key concepts, which have been divided into three categories: Core, Adjacent, and Peripheral concepts. Each chapter focuses on one important concept, shows how anarchists have understood the concept, and highlights its relationships to other concepts. Although anarchism is often thought of as a political topic, the interdisciplinary nature of Anarchism: A Conceptual Approach makes it of interest to students and scholars across the social sciences, liberal arts, and the humanities.

Artificial intelligence (AI) is increasingly expected to disrupt the ordinary functioning of society. From how we fight wars or govern society, to how we work and play, and from how we create to how we teach and learn, there is almost no field of human activity which is believed to be entirely immune from the impact of this emerging technology. This poses a multifaceted problem when it comes to designing and understanding regulatory responses to AI. This article aims to: (i) (...) defend the need for a novel conceptual model for understanding the systemic legal disruption caused by new technologies such as AI; (ii) to situate this model in relation to preceding debates about the interaction of regulation with new technologies (particularly the ‘cyberlaw’ and ‘robolaw’ debates); and (iii) to set out a detailed model for understanding the legal disruption precipitated by AI, examining both pathways stemming from new affordances that can give rise to a regulatory ‘disruptive moment’, as well as the Legal Development, Displacement or Destruction that can ensue. The article proposes that this model of legal disruption can be broadly generalisable to understanding the legal effects and challenges of other emerging technologies. (shrink)

Through engagement with key informants and review of ethical theories applicable to refugee policy, this paper examines the ethical and policy considerations that policy-level stakeholders believe should factor into setting the refugee resettlement ceiling. We find that the ceiling traditionally has been influenced by policy goals, underlying values, and practical considerations. These factors map onto several ethical approaches to resettlement. There is significant alignment between U.S. policy interests and ethical obligations toward refugees. We argue that the refugee ceiling should be (...) restored to historical norms, and that there exists a corresponding obligation to counter negative public perceptions about refugees and the costs of resettlement.

We develop a Priestley-style duality theory for different classes of algebras having a bilattice reduct. A similar investigation has already been realized by B. Mobasher, D. Pigozzi, G. Slutzki and G. Voutsadakis, but only from an abstract category-theoretic point of view. In the present work we are instead interested in a concrete study of the topological spaces that correspond to bilattices and some related algebras that are obtained through expansions of the algebraic language.

In his day, Joseph Priestley (1733-1804) was a philosopher of some importance. He argued the case for materialism perhaps more cogently than did any British thinker before recent times. He presented determinism vigorously, with a focus on the central issue of the nature of causation. He defended scientific realism against Reid’s Common Sense realism and against Hume’s phenomenonalism. He articulated a working scientist’s account of causation, induction and scientific progress. He defended the Argument from Design against Hume’s criticisms. His (...) attempt to combine theism, materialism and determinism is audacious and original. As a political thinker, he argued the case for extensive civil liberties. He was perhaps the most thorough British exponent of a Providentialist account of progress. His ultimate aim was to combine Enlightenment principles with a modernized Christian theism. (shrink)

This essay compares and contrast Priestley and Burke on the nature of progress and politics and why, after having begun as political comrades, they arrived at such different evaluations of the French Revolution. Priestley had a robust account of progress, Burke a fragile one. Priestley's ideal, unlike Burke's, was not that of civic virtue but that of commercial virtue. By restricting the scope of government, Priestley diminished the status of the political virtues.

As any fan of Leonard Cohen will tell you, many of his songs are deeply “philosophical,” in the sense that they deal reflectively and intelligently with the many of the basic issues of everyday human life, such as death, sex, love, God, and the meaning of life. It may surprise these same listeners to discover that much of academic philosophy (both past and present) has relatively little in common with this sort of introspective reflection, but is instead highly abstract, (...) methodologically complex, and filled with technical terminology that can make it inaccessible to anyone except specialists. This is not true of all philosophy, however, and Cohen’s focus on the immediate problems facing ordinary humans has much in common with the theories and ideas proposed by the Hellenistic philosophers who dominated the intellectual life of Greek- and Roman-influenced Europe for almost a thousand years. In this essay, I’ll use Cohen’s songs to examine the three major branches of Hellenistic thought: Stoicism (That’s No Way to Say Goodbye, If It Be Your Will), Epicureanism (Everybody Knows, Closing Time), and Skepticism (Famous Blue Raincoat, Different Sides).

Joseph Priestley was a man of many and varied intellectual interests. This thesis surveys his philosophical thought, with a central focus on his philosophical theology. The subject can be divided into two parts, natural theology and moral theology. Priestley's natural theology is a perhaps unique attempt to combine and harmonize materialism, determinism and theism, under the auspices of Newtonian methodology. His materialism is based on three arguments: that interaction between matter and spirit is impossible; that a dynamic theory (...) of matter breaks down the active/passive dichotomy assumed by many dualists; and that Newton's "Rules of Reasoning in Philosophy" require the rejection of the "hypothesis" of the soul. His determinism arises from his theory of causation. He attempts to show that the only acceptable account of causation is one in which every cause is invariably followed by the same effect, and that libertarianism violates this central assumption of scientific thought. His theism rests on the Argument from Design. He defends the Argument by trying to show that none of the alternatives to Design advanced in Hume's Dialogues concerning Natural Religion constitute a plausible scientific hypothesis. His critics accused his synthesis of materialism, determinism and theism of leading to atheism or pantheism. His defence against these charges is that his system is essentially theistic, and that its ontology is determined by the Argument from Design. Priestley's moral theology is also in part a response to Hume's Dialogues. He offers a number of replies to the "problem of evil". Evil and adversity heighten our appreciation of good; they are a consequence of the finitude of the creation; they follow from the desirability of having a world governed by general laws; and they make possible the achievement of moral character. Character-formation is his main defence, and his methodology requires him to show that adversity leads more often than not to positive results. This requirement is embodied in his progressivist philosophy of history. History, he holds, exhibits temporal purpose and Design, just as nature exhibits atemporal purpose and Design. Priestley's political thought can be seen as arising from his moral theology, mediated by the notions of "luxury", which he regards as morally harmless, and "idleness", which is the main source of moral evil. His combination of liberalism and radicalism is examined both for internal consistency and as a response to the events of his day, ending with the French Revolution. Priestley is interesting partly for his unorthodoxy, partly for the inter-connectedness of his diverse concerns, and partly because he debated with distinguished contemporaries. Throughout the thesis his views are juxtaposed with those of Hume, Reid, Price, Boscovich, Burke and a number of other thinkers. (shrink)

The mature materialism of Joseph Priestley's Disquisitions relating to Matter and Spirit of 1777 is based on three main arguments: that Newton's widely-accepted scientific methodology requires the rejection of the 'hypothesis' of the soul; that a dynamic theory of matter breaks down the active/passive dichotomy assumed by many dualists; and that interaction between matter and spirit is impossible. In Matter and Spirit it is the first two arguments which are given greatest prominence; but it is the third argument which (...) first brought Priestley to take materialism seriously. It was an argument which had persistently troubled him in his dualist years, but it was not until 1774 in the Examination that he 'first entertained a serious doubt of the truth of the vulgar hypothesis'. Underlying this fact is an episode of some complexity which this article examines. (shrink)

Článek se snaží přiblížit přístup Josepha Priestleyho ke zkoumání lidské mysli. Postupně jsou ukázány dva kroky, ve kterých Priestley mění svůj pohled na hmotu a ducha a dochází k materialismu. V prvním kroku redefinuje pojem hmoty a přisuzuje hmotě zcela nové vlastnosti – síly přitahování a odpuzování. V druhém kroku pomocí těchto nových vlastností vysvětluje schopnost vnímání a myšlení. V těchto krocích navíc využívá poznatky tehdejší přírodní filosofie, zejména mechaniky. Člověk a jeho mysl jsou podle Priestleyho součástí přírody. To (...) znamená, že člověk a lidská mysl jsou určitým mechanismem, který pracuje podle přírodních zákonů a lze jej pomocí těchto zákonů také vysvětlit. (shrink)

Reid said little in his published writings about his contemporary Joseph Priestley, but his unpublished work is largely devoted to the latter. Much of Priestley's philosophical thought- his materialism, his determinism, his Lockean scientific realism- was as antithetical to Reid's as was Hume's philosophy in a very different way. Neither Reid nor Priestley formulated a full response to the other. Priestley's response to Reid came very early in his career, and is marked by haste and immaturity. (...) In his last decade Reid worried much about Priestley's materialism, but that concern never reached publication. I document Reid's unpublished response to Priestley, and also view Reid's response from Priestley's perspective, as deduced from his published works. Both thinkers attempted to base their arguments on Newtonian method. Reid's position is the more puzzling of the two, since he nowhere makes clear how Newtonian method favours mind-body dualism over materialism, which is the central debate between them. (shrink)

Christopher Nolan’s Memento illustrates and explores two roles that memory plays in human life. The film’s protagonist, Leonard Shelby, cannot ‘make new memories’. He copes by using a ‘system’ of polaroids, tatoos, charts and notes that substitutes for memory in its first role, the retention of information. In particular, the system is supposed to help Leonard carry out his sole goal: to find and kill his wife’s murderer. In this it proves a disastrous failure. But are we so (...) very much better off? The film uses the failures of Leonard’s system to raise doubts about the effectiveness of our own psychological capacities for grasping the past. However, memory does more than allow us to retain information. As Richard Wollheim showed, it also enables the past to control our present, by perpetuating, while modifying, its affective hold over us. This is something wholly denied Leonard. By implicitly contrasting his position with ours in this respect, the film also explores this second role that memory plays in our lives. (shrink)

The subject of the paper is a polemic between Leonard Nelson and Ernst Cassirer mainly concerning the understanding of the critical method in philosophy. Nelson refutes the accusation of psychologism and attacks the core of the philosophy of the Marburg School of Neo-Kantianism. In response to those allegations, Cassirer feels obliged to defend the position of his masters and performs this task brilliantly. The present paper considers similarities and differences in the positions of both sides in this debate. I (...) try to evaluate the arguments of both sides and argue that they took basically the same positions, while the existing discrepancies did not justify such an intense polemic. If the disputing sides had approached the discussion in a less emotional way, it could have led to substantive and interesting conclusions. (shrink)

Naturwissenschaften, Mathematik und Logik waren für Nelson von zentraler Bedeutung. Er pflegte bereits als Jugendlicher intensive Kontakte zu Naturwissenschaftlern und Mathematikern. Dadurch erhielt er Anregungen, die von Anfang an seine philosophischen Ansätze beeinflussten. Inspiriert von der Kant-Fries’schen Philosophie und der Axiomatik der Mathematik, konzipierte Nelson seine Philosophie als exakte Wissenschaft. Wie Kant und Fries betrachtete Nelson die Suche nach den allgemeinen Prinzipien der Naturwissenschaften als Hauptaufgabe der Naturphilosophie. Ergebnis dieser kritischen Analyse ist ein System von metaphysischen Grundsätzen der Naturwissenschaft. Nelson (...) übernimmt Kants Lehre von den Grundsätzen des reinen Verstandes. Keine empirisch gefundene Gesetzmäßigkeit könne diesen Grundsätzen widersprechen. Für die Gesetze der Newton’schen Mechanik hätten, so meint Nelson, Kant und Fries diesen Nachweis erbracht. Deshalb formulierte Nelson das sogenannte Postulat der Mechanistik, gemäß dem alle Naturerscheinungen auf mechanische Vorgänge zurückgeführt werden können. Das starre Festhalten an diesem Postulat veranlasste ihn zur Ablehnung bedeutsamer physikalischer Konzeptionen (z. B. des auf der Elektrodynamik basierenden Relativitätsprinzips, des Nahwirkungskonzepts und des Atommodells). Das „Relativitätsprinzip der Elektrodynamik“ lehnte er mit dem Argument ab, es verhindere die Anwendung der dritten Analogie der Erfahrung, da es den Verzicht auf den Begriff der Gleichzeitigkeit von Naturerscheinungen erzwinge. Eine kritische Nelson-Rezeption muss der Historizität etlicher Thesen Nelsons Rechnung tragen, aber zugleich die Bedeutsamkeit von Kernaussagen Nelson’scher Naturphilosophie im Hinblick auf die modernen Naturwissenschaften untersuchen. Das ist auch die Zielrichtung des vorliegenden Beitrages. Der erste Teil beleuchtet Nelsons wissenschaftliches Umfeld. Einerseits wird untersucht, welche Wissenschaftler Nelson beeinflussten, andererseits soll dargestellt werden, welcher Personenkreis an der Fortentwicklung der Nelson’schen Naturphilosophie beteiligt war. Beispielhaft sollen daran anschließend zwei Themenbereiche aus seinem reichhaltigen Werk disktiert werden, denen besonders im Hinblick auf aktuelle philosophische Diskussionsschwerpunkte Bedeutsamkeit zukommt. Im zweiten Teil werden nämlich Nelsons Betrachtungen zum Verhältnis von Freiheit und Naturnotwendigkeit sowie seine Unterscheidung zwischen wissenschaftlicher und ästhetischer Naturbetrachtung besprochen. Der Beitrag beansprucht nicht, die Rezeptionssgeschichte und den Inhalt von Nelsons Naturphilosophie sowie die aktuelle Bedeutsamkeit seiner Thesen im Detail darzustellen aufzuarbeiten. Vielmehr geht es darum, Ansätze für eine zeitgemäße Interpretation Rezeption aufzuzeigen und anhand von Beispielen zu erörtern. (shrink)

In this paper, modelling designing and simulation of a Ward Leonard layout system is done using robust control theory. In order to increase the performance of the Ward Leonard layout system with H  optimal control synthesis and H  optimal control synthesis via -iteration controllers are used. The open loop response of the Ward Leonard layout system shows that the system needs to be improved. Comparison of the Ward Leonard layout system with H  optimal (...) control synthesis and H  optimal control synthesis via -iteration controllers to track a desired step speed input have been done. Finally, the comparative simulation results prove the effectiveness of the proposed Ward Leonard layout system with H  optimal control synthesis controller in improving the percentage overshoot and the settling time.

Karl Popper has often been cast as one of the most solitary figures of twentieth-century philosophy. The received image is of a thinker who developed his scientific philosophy virtually alone and in opposition to a crowd of brilliant members of the Vienna Circle. This paper challenges the received view and undertakes to correctly situate on the map of the history of philosophy Popper’s contribution, in particular, his renowned fallibilist theory of knowledge. The motive for doing so is the conviction that (...) the mainstream perspective on Popper’s philosophy makes him more difficult to understand than might otherwise be the case. The thinker who figures most significantly in the account of Popper developed in these pages is Leonard Nelson. Both a neo-Friesian and neo-Kantian, this philosopher deeply influenced Popper through his student Julius Kraft, who met with Popper on numerous occasions in the mid 1920s. It is in the light of this influence that we understand Popper’s recollection that when he criticized the Vienna Circle in the early 1930s, he looked upon himself “as an unorthodox Kantian”.

Hume presenta su teoría estética en el ensayo Sobre el criterio del gusto [On the Standard of Taste], en el que propone la existencia de un criterio [standard] capaz de zanjar discusiones de gusto. Ese criterio se basa en la existencia de ciertas formas y cualidades que complacen naturalmente a todo ser humano. Hume asevera que tal criterio corresponde a la opinión del crítico: un hombre que ha desplegado particularmente sus facultades cognoscitivas, lo cual le permite percibir esas finas cualidades (...) que suscitan naturalmente el placer de lo bello en el ser humano. Con respecto a en qué consisten esas formas y cualidades universalmente placenteras, Hume guarda silencio. Pretendo mostrar cómo la teoría de la emoción en la música desarrollada por Leonard Meyer en su texto Emoción y significado en la música (Emotion and Meaning in Music) puede aportar inmensidades en ese aspecto.
