We examine the relationship between the logics of nonsense of Bochvar and Halldén and the containment logics in the neighborhood of William Parry’s A I. We detail two strategies for manufacturing containment logics from nonsense logics—taking either connexive and paraconsistent fragments of such systems—and show how systems determined by these techniques have appeared as Frederick Johnson’s R C and Carlos Oller’s A L. In particular, we prove that Johnson’s system is precisely the intersection of Bochvar’s B 3 and Graham (...) Priest’s non-symmetrized connexive logic and that Oller’s system lies just beneath the intersection of B 3 and Priest’s paraconsistent L P. We conclude by examining Oller’s system in more depth, giving it a characterization in terms of L P and showing that it plays the same role to Harry Deutsch’s paraconsistent containment logic S that Aleksandr Zinov'ev’s S 1 plays with respect to A I.

1. Kierkegaard on saying and showing. The paper explores certain parallels between Kierkegaard's Concluding Unscientific Postscript and Wittgenstein's Tractatus. The following five parallels appear to exist between these two works: both draw a distinction between sense and nonsense; both distinguish between what can be said and what can only be shown; both aspire to show what cannot be said by drawing limits to what can be said; both end by retracting themselves; both imply that silence is the only correct form (...) of answer to certain questions they pose. I argue that the standard interpretation of each of these works has them inside out: a proper understanding of parallels and reveals both works to be concerned with undermining a doctrine of ineffability. I try to show that although parallels , , and depend upon a misreading of these works they, too, are nevertheless connected to deep and interesting genuine parallels in the respective philosophical undertakings of these two authors. ;2. Nietzsche's perfectionism. Nietzsche has been read as advancing a form of perfectionism in both moral and political philosophy. I argue against the standard reading of Nietzsche as defending some form of moral or political elitism. The argument is based on a careful examination of Nietzsche's third Untimely Meditation--a text frequently drawn upon to support an extreme elitist interpretation of Nietzsche. I go on to suggest that Nietzsche's views are, nonetheless, aptly characterized as perfectionist in certain respects and that they represent a striking development of certain strains of perfectionist thought that have been either widely neglected or prematurely dismissed in contemporary moral and political philosophy. ;3. The James/Royce Debate on the theory of truth. The paper argues that to understand William James' mature views one needs to situate his writing within the polemical context of the period in which he wrote and, in particular, to view his development against the background of his ongoing dialogue with Josiah Royce. I outline three successive arguments Royce deploys in an attempt to show that James' pragmatic theory of truth is self-refuting. I argue that the pressure these arguments exert on James leads him to develop a more nuanced and original form of pragmatism than has hitherto generally been appreciated. (shrink)

In this article, we consider variations of Nuel Belnap’s ‘artificial reasoner’. In particular, we examine cases in which the artificial reasoner is faulty, e.g. situations in which the reasoner is unable to calculate the value of a formula due to an inability to retrieve the values of its atoms. In the first half of the article, we consider two ways of modelling such circumstances and prove the deductive systems arising from these two types of models to be equivalent to Graham (...) Priest’s first-degree entailment with an ‘emptiness’ value and Richard Angell’s analytic containment, making computational interpretations of these systems possible. The Belnap-type semantics for AC bring FDE φ and AC in line with other containment logics in their neighborhood. The second half of the article examines formal questions, such as whether AC admits an analysis along the lines of that given to the related system of William Parry’s system of analytic implication, as suggested by Kurt Gödel and confirmed by Kit Fine. Furthermore, a natural means of extending these systems to languages with an intensional implication connective is investigated. (shrink)

In frameworks in which _topic-__theoretic_ considerations—_e.g._, tracking _subject-matter_ or _topic_—are given equal importance with _veridical_ considerations, assigning topics to formulae in a satisfactory way is of critical importance. While intuitions are more-or-less solid for _extensional_ formulae in a propositional language, arriving at a compelling account of the subject-matter of _intensional_ formulae, _i.e._, formulae including intensional operators, is more challenging. This paper continues previous work on modeling topics of intensional formulae in William Parry’s logic of analytic implication, adapting the general (...) techniques to the framework of _topic-sensitive intentional modals_ (TSIMs) championed by Francesco Berto and his collaborators. As illustrations, we introduce variations on Berto and Peter Hawke’s logic of knowability relative to information ( \(\pmb {\textsf{KRI}}\) ), including a refinement sensitive to topic-theoretic distinctions between knowledge and belief and a refinement capable of internalizing its own properties. Finally, subsystems of Aybüke Ozgun and Berto’s logic of plain hyperintensional belief ( \(\pmb {\textsf{PHB}}\) ) are introduced in which fine-grained distinctions in subject-matter are possible.

Logical frameworks that are sensitive to features of sentences’ subject-matter—like Berto’s topic-sensitive intentional modals (TSIMs)—demand a maximally faithful model of the topics of sentences. This is an especially difficult task in the case in which topics are assigned to intensional formulae. In two previous papers, a framework was developed whose model of intensional subject-matter could accommodate a wider range of intuitions about particular intensional conditionals. Although resolving a number of counterintuitive features, the work made an implicit assumption that the subject-matter (...) of an intensional conditional is a function of the subject-matters of its subformulae. This assumption—which I will call a principle of topic sufficiency—runs counter to some natural intuitions concerning topic. In this paper, we will investigate topic sufficiency and offer a semantic account that is state-sensitive, providing an implementation through the introduction of topic-sensitive logics related to William Parry’s prototypical $\mathsf {PAI}$.

According to G E Moore,1 we commit the naturalistic fallacy when we infer ‘x is good’ from non-evaluative premises involving x such as ‘ x is pleasant’ or ‘ x is desired’. On Moore’s view, the mistake is to think that we can reduce moral goodness to anything else or explain it in any other terms. We cannot analyse ‘good’, Moore thought, because goodness is simple, non-natural and sui generis. If Moore were alive today, and if he were to ask (...) contemporary bioethicists the right questions, he would probably find that many of them commit the naturalistic fallacy when they move from empirical premises to normative conclusions or when they articulate complex notions of the good. Pugh et al 2 might commit the naturalistic fallacy themselves when they conclude that people with natural immunity to COVID-19 should be exempt from vaccine mandates because such exemptions would achieve desired public health benefits. Moore would probably find me guilty of committing the naturalistic fallacy if I were to present my arguments against such exemptions. A reanimated Moore would find that the naturalistic fallacy pervades bioethics and public health. In contrast, as I shall argue, the un naturalistic fallacy is probably nowhere to be found. In this commentary, I explain what the so-called unnaturalistic fallacy really is and raise doubts about whether anyone really commits it. Decades after Moore published Principia Ethica, Bernard Williams observed that the naturalistic fallacy is unfortunately named since it is neither a fallacy nor an argumentative tendency unique to ethical naturalists.3 Ethical non-naturalists make the same mistake—if it is a mistake—when they move from, say, ‘x is commanded by the gods’ to ‘x is good’. Just as Moore’s ‘naturalistic fallacy’ misnames, Pugh et al ’s ‘unnaturalistic fallacy’ misleads. To be …. (shrink)

Like many intensional logics, William Parry’s logic of analytic implication PAI admits extensions determined by imposing semantic conditions on its account of modality. PAI is unique, however, in its allowing a second dimension—a topic-theoretic dimension—along which extensions can be defined. The recent introduction by Francesco Berto of topic-sensitive intentional modals (TSIMs)—which disagree with PAI on this type of condition—provide further motivations to examine such topic-theoretic extensions. In this paper, we introduce, motivate, and characterize a number of such extensions of (...) PAI, paying special attention to applications to Berto’s framework and to ways in which the modal and topic-theoretic dimensions influence one another. (shrink)

Critics of SRI have said little about the integrity of corporate representations resulting in screening inclusion or exclusion. This is surprising given social and environmental accounting research that finds corporate posturing and deception in the absence of external verification, and a parallel body of literature describing corporate "greenwashing" and other forms of corporate disinformation. In this paper I argue that the problems and challenges of ensuring fair and accurate corporate social reporting mirror those accompanying corporate compliance with law. Similarities and (...) points of convergence between social reporting and corporate compliance are discussed, along with proposals for reform. (shrink)

By comparing mechanisms in nativism, empiricism, and culturalism, the target article by Steels & Belpaeme (S&B) emphasizes the influence of communicational constraint on sharing color categories. Our commentary suggests deeper considerations of some of their claims, and discusses some modifications that may help in the study of communicational constraints in both humans and robots.

William S. Robinson has for many years written insightfully about the mind-body problem. In Understanding Phenomenal Consciousness he focuses on sensory experience and perception qualities such as colours, sounds and odours to present a dualistic view of the mind, called Qualitative Event Realism, that goes against the dominant materialist views. This theory is relevant to the development of a science of consciousness which is now being pursued not only by philosophers but by researchers in psychology and the brain sciences. (...) This provocative book will interest students and professionals who work in the philosophy of mind and will also have cross-disciplinary appeal in cognitive psychology and the brain sciences.

The formal systems of logic have ordinarily been regarded as independent of biology, but recent developments in evolutionary theory suggest that biology and logic may be intimately interrelated. In this book, William Cooper outlines a theory of rationality in which logical law emerges as an intrinsic aspect of evolutionary biology. This biological perspective on logic, though at present unorthodox, could change traditional ideas about the reasoning process. Cooper examines the connections between logic and evolutionary biology and illustrates how logical (...) rules are derived directly from evolutionary principles, and therefore have no independent status of their own. Laws of decision theory, utility theory, induction, and deduction are reinterpreted as natural consequences of evolutionary processes. Cooper's connection of logical law to evolutionary theory ultimately results in a unified foundation for an evolutionary science of reason. It will be of interest to professionals and students of philosophy of science, logic, evolutionary theory, and cognitive science. (shrink)

Against the Manichees, Augustine argued that sin must involve a free exercise of will. Otherwise it will not count as the agent's own act for which the agent is morally responsible. In the 390's, however, Augustine became convinced that only the first humans sinned by free exercise of will. This view faced him with the question: how is it that unambiguously good agents come to will the evil? Augustine found no satisfactory solution, and the first evil will appears, on his (...) reckoning, to be either a random outcome or due to a withholding of grace. Despite his best efforts, his account of moral agency in evil remains flawed. (shrink)

In a careful exposition of French Marxism, William Lewis places Althusser and his thought alongside the pre- and post-war French communist intellectual climate: the result is an excellent and unique work. Part theoretical treatise on some of Althusser's more complicated and less explored ideas, part intellectual history, Louis Althusser and the Traditions of French Marxism is, in total, an important text for philosophy, French and francophone studies, political thought, cultural studies, marxist thought, and several other disciplines interested in the (...) intellectual life and times of the twientieth century.

Contemporaries often reject epiphenomenalism out of hand, while Russellian Monism is regarded as worthy of further development. It is argued here that this difference of attitudes is indefensible, because the easy rejection of EPI is due to its violating a certain Causal Intuition, and RM implicitly violates that same intuition. An enriched version of RM mitigates the violation, but the same mitigation results if we make a parallel enrichment of EPI. If RM and EPI are approached on a level playing (...) field, it is not obvious which will prove to be the better view. (shrink)

This book presents and survey of the foundations of mathematics. The emphasis is on a mathematical comparison of systems rather than on any exhaustive development of analysis within a single system. Nevertheless, for most systems considered, enough details are given for the development of arithmetic, and the method of constructing the other notions of analysis is indicated. The elements of the general theory of cardinal and ordinal numbers are also furnished in the course of this work.

This paper argues that the reading of Althusser which finds a pronounced continuity in his conception of the relations among science, philosophy, and politics is the correct one, this essay will begin with an examination of Althusser’s “scientism.” The meaning of this term (one that differs slightly from contemporary usages) will be specified before showing how and in what way Althusser’s political philosophy between 1960 and 1980 can be described as “scientistic.” The next section details the important political role Althusser (...) assigned to the sciences and particularly to the science of historical materialism during this period. This accomplished, the arguments of interpreters who emphasize the apparent difference in Althusser’s attitude towards science before and after 1980 will be considered. Here, possible reasons for such a reading will be rehearsed. Next, with the support of recently published and archival documents, this essay will engage in a close and comparative reading of Althusser’s texts from the 1970s and 1980s that have as their subject the relations among philosophy, science, and politics. This survey will show the continuity in Althusser’s position vis-à-vis the sciences: namely, that if we want good (i.e. desired) socio-politico-economic changes to result from our political actions, then it is necessary to engage in social scientific research or, at the very least, to consult such research and to use this knowledge in our political decision making. All this serves to support the conclusion that Althusser’s “new” political philosophy from the 1980s is not really so new. On the contrary, his writings on the materialism of the encounter and aleatory materialism represent prolongations and elaborations of positions and ideas already developed in the 1960s and 1970s and that include a mostly consistent understanding of the relations between scientific knowledge and political action. This is true even if the rhetorical and philosophical style in which these ideas are put forth in the 1980s differs from the ways in which these ideas were introduced during the prior two decades.

Efforts to institutionalize ethics in corporations have been discussed without first addressing the desirability of norm conformity or the possibility that the means used to elicit conformity will be coercive. This article presents a theoretical context, grounded in models of social control, within which ethics initiatives may be evaluated. Ethics initiatives are discussed in relation to variables that already exert control in the workplace, such as environmental controls, organizational controls, and personal controls.

_Exploration of Alfred North Whitehead's influence on Maurice Merleau-Ponty's ontology of nature._.

The logical properties of the 'if-then' connective of ordinary English differ markedly from the logical properties of the material conditional of classical, two-valued logic. This becomes apparent upon examination of arguments in conversational English which involve (noncounterfactual) usages of if-then'. A nonclassical system of propositional logic is presented, whose conditional connective has logical properties approximating those of 'if-then'. This proposed system reduces, in a sense, to the classical logic. Moreover, because it is equivalent to a certain nonstandard three-valued logic, its (...) decision procedure is almost as efficient as that of the classical logic. It therefore provides a rational and convenient system in which to formalize English arguments. (shrink)

Silent thinking is often accompanied by subvocal sayings to ourselves, imagery, emotional feelings, and non-sensory experiences such as familiarity, rightness, and confidence that we can go on in certain ways. Phenomenological materials of these kinds, along with our dispositions to give explanations or draw inferences, provide resources that are sufficient to account for our knowledge of what we think, desire, and so on. We do not need to suppose that there is a distinctive, non-imagistic 'what it is like' to think (...) that p, and a different non-imagistic 'what it is like' to think that q. Nor need we suppose that there is a proprietary 'what it is like' to have one propositional attitude type rather than another. (shrink)

Plato's Sophist provides a careful translation of the Sophist, one of Plato's most complex and difficult dialogues, and includes materials designed to facilitate its usefulness as a text in college courses. The translation employs a minimum of interpretative paraphrasing while being presented in clear, readable English. Special attention has been given to consistency in translating key Greek terms. The book presents a special list of these terms and discusses them in the endnotes. The result is a translation that enables the (...) reader who lacks a knowledge of Greek to get much closer than usual to the original text. Cobb's introduction contains a detailed summary of the entire dialogue, clarifying the main themes and the general structure. He offers a fresh interpretation of the dialogue that shows how each theme contributes to the exploration of the nature of, and the relation between, philosophy and sophistry. The introduction is particularly useful to first readers of the Sophist. (shrink)

According to epiphenomenalism, our behavior is caused by events in our brains that also cause our mentality. This resulting mentality reflects our brains¿ organization, but does not in turn cause anything. This book defends an epiphenomenalist account of philosophy of mind. It builds on the author¿s previous work by moving beyond a discussion of sensations to apply an epiphenomenalist outlook to other aspects of mental causation such as beliefs, desires, pleasure, and displeasure. The first four chapters of the book argue (...) for a dualistic theory of sensations and develop an epiphenomenalist version of dualism. The remaining chapters discuss propositional attitudes and valence. The author also responds to potential objections to epiphenomenalism by considering how sensations, intelligence, or understanding might be built into a robot. This book will be of interest to scholars and students in philosophy of mind who are interested in consciousness, mental causation, and how our mentality is situated in the world. (shrink)

This paper begins with a summary of an argument for epiphenomenalism and a review of the author's previous work on the self-stultification objection to that view. The heart of the paper considers an objection to this previous work and provides a new response to it. Questions for this new response are considered and a view is developed in which knowledge of our own mentality is seen to differ from our knowledge of external things.

Globalization and the Posthuman argues that by globalizing posthumanism through biotechnology, particularly through the invasive interface of humans and machines, we may well interfere with and even undermine the innate quality of human psycho-physiology and the experience of the internal observer, the non-socially constructed self or pure consciousness. Furthermore, many features of globalization in-and-of itselfâ "such as the fall of public man, the exterritorialization of capital, the loss of an impersonal public world to localized communities based on emotively shared interestsâ (...) "combined with the posthuman expansion of biotechnology will diminish our natural capacity to experience the self as knower and lead to an increase in global crime, sickness, accident rates and overall lack of harmony. The experience of the self comprises the unsayable secret of modern and postmodern literature and art, a secret that may soon become inaccessible if the world continues down the road of globalized infomania. The analysis of the consequences of globalization and the posthuman in this book is unique in that it will be the first to examine the interrelation between globalization, posthumanism and pure consciousness. Posthumanists define consciousness in a way that promotes the globalization of biotechnology without regard for its potential risks. This book explores the implications of the globalization of the posthuman model of consciousness. On the one hand, cognitive scientists tend to equate consciousness with subjectivity, which they associate with the thinking mind as an extension of the body, nature and culture; Eastern philosophy, on the other hand, distinguishes mind from consciousness, with mind defined as the content of consciousness. Bionic technology will have the effect of raising human metabolism and preventing the mind from settling down to the state of least excitation of consciousness. This book suggests that while conscious content is an indispensable aspect of both the human and posthuman condition, the thoughts, memories, feelings and perceptions of this content do not encompass a vital aspect of human nature attested to not only by the first-person experience of many millions of people around the world, but also by the records of both classical and modern contemplative traditions.
