This paper studies the relationship between Argumentation Logic, a recently defined logic based on the study of argumentation in AI, and classical Propositional Logic. In particular, it shows that AL and PL are logically equivalent in that they have the same entailment relation from any given classically consistent theory. This equivalence follows from a correspondence between the non-acceptability of sentences in AL and Natural Deduction proofs of the complement of these sentences. The proof of this equivalence uses a restricted form (...) of ND proofs, where hypotheses in the application of the Reductio of Absurdum inference rule are required to be “relevant” to the absurdity derived in the rule. The paper also discusses how the argumentative re-interpretation of PL could help control the application of ex-falso quodlibet in the presence of inconsistencies. (shrink)

This paper presents a way in which formal logic can be understood and reformulated in terms of argumentation that can help us unify formal and informal reasoning. Classical deductive reasoning will be expressed entirely in terms of notions and concepts from argumentation so that formal logical entailment is equivalently captured via the arguments that win between those supporting concluding formulae and arguments supporting contradictory formulae. This allows us to go beyond Classical Logic and smoothly connect it with human reasoning, thus (...) providing a uniform argumentation-based view of both informal and formal logic. (shrink)

Can argumentation form the basis for any form of reasoning, informal or formal logical reasoning? We examine this question from the particular perspective of the recent developments in logic-based Artificial Intelligence (AI). We propose that argumentation provides the wider framework encompassing uniformly all reasoning, with strict or formal logical reasoning being a special boundary case. We also attempt to link this unifying role of argumentation with Aristotle’s original investigation of methods and forrmalisms for the systematic study of human reasoning.

Alan Robinson This set of essays pays tribute to Bob Kowalski on his 60th birthday, an anniversary which gives his friends and colleagues an excuse to celebrate his career as an original thinker, a charismatic communicator, and a forceful intellectual leader. The logic programming community hereby and herein conveys its respect and thanks to him for his pivotal role in creating and fostering the conceptual paradigm which is its raison d’Œtre. The diversity of interests covered here reflects the variety of (...) Bob’s concerns. Read on. It is an intellectual feast. Before you begin, permit me to send him a brief personal, but public, message: Bob, how right you were, and how wrong I was. I should explain. When Bob arrived in Edinburgh in 1967 resolution was as yet fairly new, having taken several years to become at all widely known. Research groups to investigate various aspects of resolution sprang up at several institutions, the one organized by Bernard Meltzer at Edinburgh University being among the first. For the half-dozen years that Bob was a leading member of Bernard’s group, I was a frequent visitor to it, and I saw a lot of him. We had many discussions about logic, computation, and language.

This study proposes that Neoplatonism, while not a modern philosophy, is philosophy in the modern sense. Lloyd analyzes the key structures that underlie the dogmas of the Neoplatonic world picture, including the concept of emanation, the return of the soul to the One, the place of mystical knowledge, epistemology, and Porphyry's theory of predication, and shows that they rest on original but intelligible concepts and arguments.

Many researchers believe the tremendous industrial development over the past two centuries is unsustainable because it has led to unintended ecological deterioration. Despite the ever-growing attention sustainable supply-chain management has received, most SSCM research and models look at the consequences, rather than the antecedents or motives of such responsible practices. The few studies that explore corporate motives have remained largely qualitative, and large-scale empirical analyses are scarce. Drawing on multiple theories and combining supply-chain and business ethics literature, we purport that (...) instrumental, relational, and moral motives are behind a firm’s engagement in SSCM practices. Specifically, we examine the links between corporate motives, SSCM practices, and firm performance. Using a sample of 259 supply-chain firms in Germany, we empirically test five hypothesized relationships. Our results reveal that relational and moral motives are key drivers, and that firms exhibiting high levels of moral obligations tend to outperform those primarily driven by amoral considerations. Findings of this study contribute to multiple literatures espousing sustainability management and can help policy makers, stakeholder groups, and scholars develop more robust strategies for encouraging firms to practice SSCM.

The current legal status and medical ethics of routine or religious penile circumcision of minors is a matter of ongoing controversy in many countries. We focus on the United Kingdom as an illustrative example, giving a detailed analysis of the most recent British Medical Association guidance from 2019. We argue that the guidance paints a confused and conflicting portrait of the law and ethics of the procedure in the UK context, reflecting deeper, unresolved moral and legal tensions surrounding child genital (...) cutting practices more generally. Of particular note is a lack of clarity around how to apply the “best interests” standard—ordinarily associated with time-sensitive proxy decision making regarding therapeutic options for a medically unwell patient—to a parental request for a medically unnecessary surgery to be carried out on the genitalia of a healthy child. Challenges arise in measuring and assigning weights to intended sociocultural or religious/spiritual benefits, and even to health-related prophylactic benefits, and in balancing these against potential physical, functional, and psychosexual risks or harms. Also of concern are apparently inconsistent safeguarding standards being applied to children based on their birth sex categorization or gender of rearing. We identify and discuss recent trends in British and international medical ethics and law, finding gradual movement toward a more unified standard for evaluating the permissibility of surgically modifying healthy children's genitals before they can meaningfully participate in the decision.

A complete history of Islamic political thought from early Islam to the present Now in its 2nd edition, this textbook describes and interprets all schools of Islamic political thought, their origins, inter-connections and meaning. It examines the Qur'an, the early Caliphate, classical Islamic philosophy and the political culture of the Ottoman and other empires. It covers major thinkers such as Averroes and Ibn Taymiyya as well as a number of lesser authors, and Ibn Khaldun is presented as one of the (...) most original political theorists ever. It draws on a wide range of sources including writings on religion, law, philosophy and statecraft expressed in treatises, handbooks and political rhetoric. The new edition analyses the connections between religion and politics, covering the most recent developments in Islamic political thought and the most recent historical scholarship. It ends with a critical survey of reformism and Islamism from the late-19th century up to the present day. (shrink)

Following the pattern set by the early German Romantics, Kierkegaard conveys many of his insights through literature rather than academic prose. What makes him a valuable member of this tradition is the theory he develops to support it, his so-called “theory of indirect communication.” The most exciting aspect of this theory concerns the alleged importance of indirect communication: Kierkegaard claims that there are some projects only it can accomplish. This paper provides a critical account of two arguments Kierkegaard offers in (...) defense of this claim. The first argument is that he needs to use indirect communication in order to discourage people from losing themselves in the “crowd”. The second argument is that he needs to use it in order to help people out of a “monstrous illusion”. It is shown that while both arguments justify Kierkegaard’s decision to use indirect communication, neither one supports the original claim about its indispensability. (shrink)

ABSTRACTIn this paper I reassess the place of Plato’s Laws in the history of legal thought. The Laws has been traditionally considered to present a natural law theory of law. I argue instead that it presents a positivist account of the nature of law. Through analysis of some key passages of the Laws I argue that in that dialogue law is identified with conclusions of enkratic civic reason that may systematically conflict with precepts of substantive moral reason. I also argue (...) that in the Laws the rule of law is a precondition of a legal system but lacks inherent moral significance. For the rule of law to obtain there needs to be some compromise between the political interests of rulers and subjects which is grounded on political pragmatism and not on moral considerations.

Studies of AGL have frequently used training and test stimuli that might provide multiple cues for learning, raising the question what subjects have actually learned. Using a selected subset of studies on humans and non‐human animals, Trotter et al. demonstrate how a meta‐analysis can be used to identify relevant experimental variables, providing a first step in asssessing the relative contribution of design features of grammars as well as of species‐specific effects on AGL.

At the beginning of Book X of his last work The Laws Plato turns his attention from violent and outrageous actions in general to the particular case of undisciplined and presumptuous behaviour in matters of religion: “We have already stated summarily what the punishment should be for temple-robbing, whether by open force or secretly. But the punishments for the various sorts of insolence in speech or action with regard to the gods, which a man can show in word or deed, (...) have to be proclaimed after we have provided an exordium. Let this be it: ‘No one believing, as the laws prescribe, in the existence of the gods has ever yet performed an impious action willingly, or uttered a lawless word. Anyone acting in such a way is in one of three conditions: either, first, he does not believe the proposition aforesaid; or, second, he believes that though the gods exist they have no concern about men; or, third, he believes that they can easily be won over by the bribery of prayer and sacrifice”.

Currently, testimony is studied extensively in Anglo-American philosophy. However, most of this work is done from a justificationist perspective in which philosophers try to justify our reliance on testimony in some way. I agree with Popper that justificationism is radically mistaken. Thus, I construct an account of how we respond to testimony that in no way attempts to justify our reliance on it. This account is not a straightforward exegesis of Popper, as he never tackled testimony systematically. It makes use, (...) however, of several of Popper's key insights and incorporates them into a viable theory of testimony. Key Words: testimony • anti-justificationism • social epistemology • situational analysis • defeasibility. (shrink)

The paper presents the territorial and axiological context and the peculiarities of the participatory project developed by the Polis Research Centre and the Bon Pastor Neighbourhood Association, as well as the first steps in the design of two interventions. The first intervention, the Wall and Party Walls in Rodriguez de la Fuente Square, is proposed within the framework of the sustainable development strategies of Barcelona City Council. Its main objective is to achieve thermal insula­tion of the affected dwellings, thus contributing (...) to the well being of the residents and to the reduc­tion of CO 2 emissions into the atmosphere. Besides, it is aimed to solve landscape discontinuity. In the lower part of the party walls, there is a wall, a kind of plinth that the residents have chosen as a site for the expansion of the work on the civic remembrance of the neighbourhood. There, the “Living Memory” space will be set up, reserved for interventions by children from the quarter’s schools through a work programme run in cooperation with them. The second intervention is the case of the centennial Mulberry Tree classified as a tree of local interest. In 2018, the mulberry tree suffered some damage from thugs who threw firecrackers inside. Therefore, the need was pointed out to reorganise the space around the tree in order to create dissuasive effects and preserve its integrity. These are preliminary studies to be discussed by the agents involved in the project: the Sant Andreu District, the IMPUQV (Institut Municipal del Paisatge Urbài la Qualitat de Vida), and the Bon Pastor Neighbourhood Association.

The Anatomy of Neoplatonism was the crowning achievement of A. C. Lloyd, the distinguished scholar of late ancient philosophy. He offers a rich and authoritative study of this school of thought, which was highly influential not only on subsequent philosophy but also on Christian theology. His discussion ranges over metaphysics, epistemology, logic, and language, and reveals the fundamental structure of Neoplatonist thought; the book is essential reading for all who work in this area. Lloyd shows that while Neoplatonism is not (...) a modern philosophy, it is indeed philosophy in the modern sense. (shrink)

Causation appears to present us with an interpretative difficulty. While arguably a redundant relation given fundamental physics, it is nevertheless apparently pragmatically indispensable. This chapter revisits certain arguments made previously by the author for these claims with the benefit of hindsight, starting with the role of causal models in the human sciences, and attempting to explain why it is not possible to straightforwardly ground such models in fundamental physics. This suggests that further constraints, going beyond physics, are needed to legitimate (...) such models. These supplementary constraints could be reified, but that would seem to conflict with the completeness of physics. A response is to emphasize the practical role of causal talk, and the author suggests that a fictionalist approach might be worth exploring. After clarifying fictionalism as a general approach, they carry out in some detail the project of clarifying what a fictionalist attitude to causation would involve. (shrink)

Material Engagement Theory is currently driving a conceptual change in the archaeology of mind. Drawing upon the dictates of enactivism and active externalism, it specifically calls for a radical reconceptualization of mind and material culture. Unpersuaded by the common assumption that cognition is brain-bound, Malafouris argues in favour of a process ontology that situates thinking in action. In granting ontological primacy to material engagement, MET seeks to illuminate the emergence of human ways of thinking through the practical effects of the (...) material world. Considering that this is a characteristic example of a pragmatic take on cognition, this contemporary theoretical platform appears to share a lot with pragmatism. As of late, scholars working at the intersection of philosophy, semiotics, and cognitive science have made important steps towards the rapprochement between pragmatism and externalism. Looking to contribute to this growing corpus of work, the present paper focuses on MET’s relation to the pragmatism of Peirce, Dewey, and Mead. Having elsewhere recognized the overlap and complementarity between Malafouris’ and Peirce’s theories in particular, I developed a pragmatic and enactive theory of cognitive semiotics that is suitably geared to trace the nature, emergence, and evolution of material signs. Therefore, besides noting some obvious historical connections, I hereby aim to establish the theoretical backdrop upon which this composite theory is supposed to function, while also exploring new potential avenues. Given that this cognitive semiotic framework can be seen as a pragmatic extension of Malafouris’ enactivist approach to archaeology, the current paper delves into MET’s theoretical underpinnings, seeking to complement its working hypotheses and concepts with philosophical notions and ideas advanced long ago. This synthesis ultimately concludes with a call for the reconceptualization of ‘representation’ as a heuristic concept. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Response 2: “Pessimism of the Intellect, Optimism of the Will”Antonis BalasopoulosLet me begin with a few words on my title, which was chosen as reflecting the nature of the orientation of my work in the field of utopian studies and therefore also of my orientation toward the theme of this roundtable. As Francesca Antonini puts it in a recent essay, the phrase, which became associated with the work (...) of Antonio Gramsci though it originates in Romain Rolland, describes “the (seemingly contradictory) coexistence of a realistic description of the status quo, on the one hand, and a genuine commitment to the possibility of transforming reality, on the other.”1Anyone who has read Thomas More’s Utopia knows that Rolland’s and Gramsci’s formula very much describes that book’s bifurcation between a voice of relentless critique of what exists in Europe—and particularly in England—in More’s time (in Book 1) and a voice preoccupied with the description of an alternative, and arguably better, world (in Book 2). This bifurcation, it is equally well known, is part of the genetic material More’s book bequeathed to its successors, so that one calls a “utopia” a (mostly, though not always) literary text, where the “realistic description of the status quo” coexists with a vision arising out of a “commitment to the possibility of transforming reality”—admittedly in different admixtures and proportions of [End Page 544] the critical or negative and the anticipatory, projective or prefigurative elements. Though Ernst Bloch’s distinction between “cold” and warm” streams within Marxism is not identical to this first binary, it is certainly related to it, so that the “cold” stream is one that privileges the rational and analytical element (usually, I would propose, in relation to the part of the Marxist tradition we know as “critique of political economy”), while the “warm stream” is one that rather foregrounds that which relates to affect, to desire, hope, or fidelity to the transformative project (these are frequently correlated to those elements of Marxism that correspond to its also being a political and philosophically imbued creed).2 What follows here, then, explores the implications of the dialectical interplay between these two sets of oppositions—and hopefully justifies such insistence on dialectic itself.3To the extent that I can see, the basic themes and areas of concentration in my colleagues’ essays involve decolonizing utopian studies as a project; addressing, in that connection, the heterogeneity of utopianisms that emerge out of a number of marginalized subjectivities; the provenance of the questions of ecology, sustainability, animal life for the present and future of utopian studies (and to some degree, for utopianism’s past); and finally, the question of utopian forms of social activism and therefore also the search for spaces beyond the walls of academic insularity. These are important and largely interconnected questions, but I am afraid I will only have the space to touch on them briefly and sketchily here.In her cogent and multifaceted intervention, Caroline Edwards begins her reflections on the task of decolonizing utopian studies by noting the high investment of fin-de-siècle utopian fiction in notions of industrial progress, noting that such notions have involved “lasting damage” for “Black writers, artists, and thinkers.” Within this framework, she evokes Joseph R. Winters’s argument that “modern notions of progress and freedom are inherently flawed,” since they are founded on the oppressive traditions of capitalism and colonialism. In turn, this leads to an argument against the teleological futurism of most nineteenth-century utopias and in support of the deconstruction of “the idea of historical progress unfolding in Hegelian dialectical stages.” What is to replace this is a hauntological (after Derrida) conception of the relation between the present and the past, for which “the present is always a site of potential breaks and ruptures that can signify both dislocation and pain as well as novelty and possibility.” In a similar vein, Heather Alberro questions the teleological futurism of an earlier tradition of utopia, evoking Laurence Davis’s observation on the importance of [End Page 545] “neglected or suppressed possibilities for qualitatively better forms of life” within the “Now.” The desideratum is, again...

This dissertation concerns Kierkegaard’s theory of indirect communication. A central aspect of this theory is what I call the “indispensability thesis”: there are some projects only indirect communication can accomplish. The purpose of the dissertation is to disclose and assess the rationale behind the indispensability thesis. -/- A pair of questions guides the project. First, to what does ‘indirect communication’ refer? Two acceptable responses exist: (1) Kierkegaard’s version of Socrates’ midwifery method and (2) Kierkegaard’s use of artful literary devices. Second, (...) for what end does Kierkegaard use indirect communication? There are two acceptable responses here as well: (1) helping others become religious and (2) making others aware of the nature of existence. -/- These responses are interrelated. First, Kierkegaard’s notion of religion places restrictions on the means he can use to get readers to become religious. These restrictions ultimately entail that the only viable form of religious pedagogy is the midwifery method. Second, Kierkegaard engages in the midwifery method in part by making readers aware of the nature of existence (especially religious existence). But given the problems plaguing his readers, he thinks a straightforward approach to this project will likely fail. An approach that used artful literary devices such as deception and humor would be more successful. Third, Kierkegaard believes that there is one aspect of religious existence (viz. subjectivity) that people can come to know only first-hand. As such, he cannot directly impart knowledge of subjectivity to his readers. He argues that this means he must use the midwifery method. And he thinks the most productive way to do so is to provide readers with the kind of fictional narratives found in his early pseudonymous writings. Thus artful rhetorical devices play a role here as well. -/- All of Kierkegaard’s arguments for the indispensability thesis turn on debatable assumptions. But the arguments concerning artful rhetorical devices have the additional defect of being merely probabilistic in nature. They lack the strength to support the indispensability thesis even if we grant the relevant background assumptions. Therefore, to the degree that the indispensability thesis has merit, it lies with the arguments concerning the midwifery method. (shrink)

In order to understand what we are talking about when we talk about joint attention, I will scrutinize how the mainstream view that builds on representational and intentionalist theories of mind is constituted. My aim is to show that much of the theory of joint attention is quite narrowly constructed and comes with tacit disciplinary biases that exclude much of what is existentially important in our practices of sharing our perceptions and guiding others to attend to the world in novel (...) ways. By using the frameworks of classical phenomenology and enactivist theories of mind, I aim to show how we, in our interactions, share our perceptions even with beings that are distinctly different from us. And, that this _difference_ in our personal worldview, our cognitive capacities, and our sensory modalities should be seen as a constitutive aspect of our practices of shared attention. I will articulate attention as a revelatory practice that aids us in discovering a shared world through the plurality, rather than similarity, of our perceptual actions. Attention is, in this sense, not solely driven by subjective intentions; it is also formed and co-constituted by my being addressed by the other. (shrink)
