This three-part paper comprises: (i) a critique by Halvorson of Bell’s (1973) paper ‘Subject and Object’; (ii) a comment by Butterfield; (iii) a reply by Halvorson. An Appendix gives the passage from Bell that is the focus of Halvorson’s critique.

Bell inequalities are usually derived by assuming locality and realism, and therefore violations of the Bell-CHSH inequality are usually taken to imply violations of either locality or realism, or both. But, after reviewing an oversight by Bell, in the Corollary below we derive the Bell-CHSH inequality by assuming only that Bob can measure along vectors b and b' simultaneously while Alice measures along either a or a', and likewise Alice can measure along vectors a and a' (...) simultaneously while Bob measures along either b or b', without assuming locality. The violations of the Bell-CHSH inequality therefore only mean impossibility of measuring along b and b' simultaneously. (shrink)

This is the review of a book by Paula Byrne on Lord Mansfield's great-niece, Dido, whom he raised as his own daughter. Lord Mansfield was the Lord Chief Justice of England in the Eighteenth Century. The child was brought to him as an infant and grew up to become what we would today term his paralegal clerk in his Library at Kenwood House. His great-niece was the child of a black slave and his sister's son, Sir John Lindsay. This (...) is also a narrative of the British Slave trade including some of Lord Mansfield's judgements at the King's Bench Division, Royal Courts of Justice. (shrink)

John von Neumann's proof that quantum mechanics is logically incompatible with hidden varibales has been the object of extensive study both by physicists and by historians. The latter have concentrated mainly on the way the proof was interpreted, accepted and rejected between 1932, when it was published, and 1966, when J.S. Bell published the first explicit identification of the mistake it involved. What is proposed in this paper is an investigation into the origins of the proof rather than (...) the aftermath. In the first section, a brief overview of the his personal life and his proof is given to set the scene. There follows a discussion on the merits of using here the historical method employed elsewhere by Andrew Warwick. It will be argued that a study of the origins of von Neumann's proof shows how there is an interaction between the following factors: the broad issues within a specific culture, the learning process of the theoretical physicist concerned, and the conceptual techniques available. In our case, the ‘conceptual technology’ employed by von Neumann is identified as the method of axiomatisation. (shrink)

Horwich donne une belle analyse de Wittgenstein (W) et est un érudit W de premier plan, mais à mon avis, ils sont tous en deçà d’une pleine appréciation, comme je l’explique longuement dans cet examen et beaucoup d’autres. Si l’on ne comprend pas W (et de préférence Searle aussi) alors je ne vois pas comment on pourrait avoir plus qu’une compréhension superficielle de la philosophie et de la pensée de l’ordre supérieur et donc de tout comportement complexe (psychologie, sociologie, anthropologie, (...) histoire, littérature, société). En un mot, W a démontré que lorsque vous avez montré comment une phrase est utilisée dans le contexte d’intérêt, il n’y a rien de plus à dire. Je vais commencer par quelques citations notables, puis donner ce que je pense sont les considérations minimales nécessaires pour comprendre Wittgenstein, la philosophie et le comportement humain. Tout d’abord, on pourrait noter que mettre "meta" en face de n’importe quel mot devrait être suspect. W a fait remarquer par exemple, que la métamathématique est mathématiques comme les autres. L’idée que nous pouvons sortir de la philosophie (c’est-à-dire la psychologie descriptive de la pensée de haut ordre) est elle-même une profonde confusion. Une autre irritation ici (et tout au long de l’écriture académique pour les 4 dernières décennies) est le sexisme linguistique inverse constant de «elle» et «la sienne» et «elle» ou «il / elle», etc, où «ils» et «leur» et «eux» ferait bien. De même, l’utilisation du mot Français «répertoire» où le «répertoire» anglais se portera plutôt bien. La lacune majeure est l’échec complet (bien que très commun) d’employer ce que je considère comme la vue extrêmement puissante et intuitive de deux systèmes de HOT et Searle cadre que j’ai décrit ci-dessus. C’est particulièrement poignant dans le chapitre sur le sens p111 et seq. (en particulier dans les notes de bas de page 2-7), où nous nageons dans l’eau très boueuse sans le cadre de l’automatisé vrai seul S1, propositionnelle dispositionnelle S2, COS etc. On peut également avoir une meilleure vue de l’intérieur et de l’extérieur en lisant par exemple, Johnston ou Budd (voir mes commentaires). Horwich fait cependant beaucoup de commentaires incisifs. J’ai particulièrement aimé son résumé de l’importation de la position anti-théorique de W sur p65. Il doit mettre davantage l’accent sur 'On Certainty', récemment l’objet de beaucoup d’efforts de Daniele Moyal- Sharrock, Coliva et d’autres et résumé dans mes récents articles. Horwich est de premier ordre et son travail vaut bien l’effort. On espère qu’il (et tout le monde) étudiera Searle et une certaine psychologie moderne ainsi que Hutto, Read, Hutchinson, Stern, Moyal-Sharrock, Stroll, Hacker et Baker, etc. pour atteindre une large vision moderne du comportement. La plupart de leurs papiers sont sur academia dot edu et philpapers dot org, mais pour PMS Hacker voir http : info dot sjc dot ox dot ac dot uk/ scr / hacker / DownloadPapers dot html. Il donne l’un des plus beaux résumés de l’endroit où une compréhension de Wittgenstein nous laisse que j’ai jamais vu. « Il ne doit y avoir aucune tentative d’expliquer notre activité linguistique/conceptuelle (PI 126) comme dans la réduction de l’arithmétique à la logique de Frege ; aucune tentative de lui donner des fondations épistémologiques (PI 124) comme dans les comptes basés sur le sens d’une connaissance a priori; aucune tentative de caractériser des formes idéalisées de celui-ci (PI 130) comme dans le sens logique; aucune tentative de réforme (PI 124, 132) comme dans la théorie de l’erreur de Mackie ou l’intuitionnisme de Dummett; aucune tentative de rationaliser (PI 133) comme dans le récit de Quine de l’existence; aucune tentative pour le rendre plus cohérent (PI 132) comme dans la réponse de Tarski aux paradoxes menteurs; et aucune tentative pour le rendre plus complet (PI 133) comme dans le règlement des questions d’identité personnelle pour des scénarios hypothétiques bizarres de « téléportation ». Enfin, permettez-moi de suggérer qu’avec la perspective que j’ai encouragée ici, W est au centre de la philosophie et de la psychologie contemporaines et n’est pas obscure, difficile ou non pertinente, mais scintillante, profonde et limpide et que de lui manquer est de manquer l’une des plus grandes aventures intellectuelles possibles. Ceux qui souhaitent un cadre complet à jour pour le comportement humain de la vue moderne de deuxemssyst peuvent consulter mon livre 'The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle' 2nd ed (2019).

The enigma of the Emergence of Natural Languages, coupled or not with the closely related problem of their Evolution is perceived today as one of the most important scientific problems. The purpose of the present study is actually to outline such a solution to our problem which is epistemologically consonant with the Big Bang solution of the problem of the Emergence of the Universe}. Such an outline, however, becomes articulable, understandable, and workable only in a drastically extended epistemic and scientific (...) oecumene, where known and habitual approaches to the problem, both theoretical and experimental, become distant, isolated, even if to some degree still hospitable conceptual and methodological islands. The guiding light of our inquiry will be Eugene Paul Wigner's metaphor of ``the unreasonable effectiveness of mathematics in natural sciences'', i.e., the steadily evolving before our eyes, since at least XVIIth century, ``the miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics''. Kurt Goedel's incompleteness and undecidability theory will be our guardian discerner against logical fallacies of otherwise apparently plausible explanations. John Bell's ``unspeakableness'' and the commonplace counterintuitive character of quantum phenomena will be our encouragers. And the radical novelty of the introduced here and adapted to our purposes Big Bang epistemological paradigm will be an appropriate, even if probably shocking response to our equally shocking discovery in the oldest among well preserved linguistic fossils of perfect mathematical structures outdoing the best artifactual Assemblers.

In this short survey article, I discuss Bell’s theorem and some strategies that attempt to avoid the conclusion of non-locality. I focus on two that intersect with the philosophy of probability: (1) quantum probabilities and (2) superdeterminism. The issues they raised not only apply to a wide class of no-go theorems about quantum mechanics but are also of general philosophical interest.

This presentation includes a complete bibliography of John Corcoran’s publications devoted at least in part to Aristotle’s logic. Sections I–IV list 20 articles, 43 abstracts, 3 books, and 10 reviews. It starts with two watershed articles published in 1972: the Philosophy & Phenomenological Research article that antedates Corcoran’s Aristotle’s studies and the Journal of Symbolic Logic article first reporting his original results; it ends with works published in 2015. A few of the items are annotated with endnotes connecting them (...) with other work. In addition, Section V “Discussions” is a nearly complete secondary bibliography of works describing, interpreting, extending, improving, supporting, and criticizing Corcoran’s work: 8 items published in the 1970s, 22 in the 1980s, 39 in the 1990s, 56 in the 2000s, and 65 in the current decade. The secondary bibliography is annotated with endnotes: some simply quoting from the cited item, but several answering criticisms and identifying errors. As is evident from the Acknowledgements sections, all of Corcoran’s publications benefited from correspondence with other scholars, most notably Timothy Smiley, Michael Scanlan, and Kevin Tracy. All of Corcoran’s Greek translations were done in consultation with two or more classicists. Corcoran never published a sentence without discussing it with his colleagues and students. REQUEST: Please send errors, omissions, and suggestions. I am especially interested in citations made in non-English publications. (shrink)

The idea that technologies can change moral beliefs and practices is an old one. But how, exactly, does this happen? This paper builds on an emerging field of inquiry by developing a synoptic taxonomy of the mechanisms of techno-moral change. It argues that technology affects moral beliefs and practices in three main domains: decisional (how we make morally loaded decisions), relational (how we relate to others) and perceptual (how we perceive situations). It argues that across these three domains there are (...) six primary mechanisms of techno-moral change: (i) adding options; (ii) changing decision-making costs; (iii) enabling new relationships; (iv) changing the burdens and expectations within relationships; (v) changing the balance of power in relationships; and (vi) changing perception (information, mental models and metaphors). The paper also discusses the layered, interactive and second-order effects of these mechanisms. (shrink)

Few problems in the philosophy of evolutionary biology are more widely disseminated and discussed than the charge of Darwinian evolution being a tautology. The history is long and complex, and the issues are many, and despite the problem routinely being dismissed as an introductory-level issue, based on misunderstandings of evolution, it seems that few agree on what exactly these misunderstandings consist of. In this paper, I will try to comprehensively review the history and the issues. Then, I will try to (...) present the following “solution”, or, one might say, “dissolution”, of the problem, and consider the wider implications of formal, or schematic, explanations in science: yes, the principle of natural selection is a tautology, and so what? It is a promissory note for actual, physical, explanations in particular cases, and is none the worse for that. This is not a new argument, of course, but it does point up the importance of formal schematic models in science. (shrink)

In this paper, I transcend the abstract engagement of J. L. Austin's Speech Acts theory and explore their sociopolitical advantages, using the Nigerian social space as my primary experimental field. Nigerian social space is quite hierarchical and progresses along apparently asymmetrical lines of social relationship (in most cases). This in turn, accentuates some sort of power dynamics. In every communication, there is an implicit reinforcement of the social fabric as well as the power dynamic, either through one person's percep6of the (...) social status of the other or, of one's emphasis of power dynamic over the other. Austin's theory comes to the fore as a very laudable framework to map this interesting sociological facts. This work then, offers a philosophical contribution to an otherwise, sociological/anthropological fact. My job in this paper, is to explore a sociopolitical negotiation of Austin's theory in a multiethnic nation-state as Nigeria where hierarchy and power dynamics are heavily emphasized. This paper thus highlights the importance of the perlocutionary acts and the felicity conditions, and also accentuates their implications for social interactions and power dynamics in the Nigerian social space.

I demonstrate that Bell's theorem is based on circular reasoning and thus a fundamentally flawed argument. It unjustifiably assumes the additivity of expectation values for dispersion-free states of contextual hidden variable theories for non-commuting observables involved in Bell-test experiments, which is tautologous to assuming the bounds of ±2 on the Bell-CHSH sum of expectation values. Its premises thus assume in a different guise the bounds of ±2 it sets out to prove. Once this oversight is ameliorated from (...) Bell's argument by identifying the impediment that leads to it and local realism is implemented correctly, the bounds on the Bell-CHSH sum of expectation values work out to be ±2√2 instead of ±2, thereby mitigating the conclusion of Bell's theorem. Consequently, what is ruled out by any of the Bell-test experiments is not local realism but the linear additivity of expectation values, which does not hold for non-commuting observables in any hidden variable theories to begin with. I also identify similar oversight in the GHZ variant of Bell's theorem, invalidating its claim of having found an inconsistency in the premisses of the argument by EPR for completing quantum mechanics. Conceptually, the oversight in both Bell's theorem and its GHZ variant traces back to the oversight in von Neumann's theorem against hidden variable theories identified by Grete Hermann in the 1930s.

Essentialism in philosophy is the position that things, especially kinds of things, have essences, or sets of properties, that all members of the kind must have, and the combination of which only members of the kind do, in fact, have. It is usually thought to derive from classical Greek philosophy and in particular from Aristotle’s notion of “what it is to be” something. In biology, it has been claimed that pre-evolutionary views of living kinds, or as they are sometimes called, (...) “natu-ral kinds”, are essentialist. This static view of living things presumes that no tran-sition is possible in time or form between kinds, and that variation is regarded as accidental or inessential noise rather than important information about taxa. In contrast it is held that Darwinian, and post-Darwinian, biology relies upon varia-tion as important and inevitable properties of taxa, and that taxa are not, therefore, kinds but historical individuals. Recent attempts have been made to undercut this account, and to reinstitute essentialism in biological kind terms. Others argue that essentialism has not ever been a historical reality in biology and its predecessors. In this chapter, I shall outline the many meanings of the notion of essentialism in psychology and social science as well as science, and discuss pro- and anti-essentialist views, and some recent historical revisionism. It turns out that nobody was essentialist to speak of in the sense that is antievolutionary in biology, and that much confusion rests on treating the one word, “essence” as meaning a single notion when in fact there are many. I shall also discuss the philosophical implica-tions of essentialism, and what that means one way or the other for evolutionary biology. Teaching about evolution relies upon narratives of change in the ways the living world is conceived by biologists. This is a core narrative issue. (shrink)

It is often noted that if someone has a tertiary degree in a scientific field who promotes an anti-science-establishment, antiscience, or pseudoscience agenda, they are very often engineers, dentists, surgeons or medical practitioners. While this does not mean that all members of these professions or disciplines are antiscience, of course, the higher frequency of pseudoscience among them is indicative of what I call the “deductivist mindset” regarding science itself. Opposing this is the “inductivist mindset”, a view that has been deprecated (...) among philosophers since Popper. Roughly, the deductivist mindset tends to see problems as questions that can be resolved by deduction from known theory or principle, while the inductivist sees problems as questions to be resolved by discovery. These form cognitive poles, which nobody ever purely instantiates, but a cognitive tendency to be a deductivist may explain why some people find results that conflict with prior theoretical commitments, whether scientific or not, unacceptable. The deductivist tends to be a cognitive conservative, where the inductivist tends to be a cognitive progressive, and the conservative mindset leads to a ressentiment about modernism, and hence about certain scientific results, more often, or so I shall argue in this chapter.

The vision of natural kinds that is most common in the modern philosophy of biology, particularly with respect to the question whether species and other taxa are natural kinds, is based on a revision of the notion by Mill in A System of Logic. However, there was another conception that Whewell had previously captured well, which taxonomists have always employed, of kinds as being types that need not have necessary and sufficient characters and properties, or essences. These competing views employ (...) different approaches to scientific methodologies: Mill’s class-kinds are not formed by induction but by deduction, while Whewell’s type-kinds are inductive. More recently, phylogenetic kinds (clades, or monophyletic-kinds) are inductively projectible, and escape Mill’s strictures. Mill’s version represents a shift in the notions of kinds from the biological to the physical sciences. (shrink)

JUNE 2015 UPDATE: A BIBLIOGRAPHY: JOHN CORCORAN’S PUBLICATIONS ON ARISTOTLE 1972–2015 By John Corcoran -/- This presentation includes a complete bibliography of John Corcoran’s publications relevant to his research on Aristotle’s logic.

Ever since Darwin people have worried about the sceptical implications of evolution. If our minds are products of evolution like those of other animals, why suppose that the beliefs they produce are true, rather than merely useful? We consider this problem for beliefs in three different domains: religion, morality, and commonsense and scientific claims about matters of empirical fact. We identify replies to evolutionary scepticism that work in some domains but not in others. One reply is that evolution can be (...) expected to design systems that produce true beliefs in some domain. This reply works for commonsense beliefs and can be extended to scientific beliefs. But it does not work for moral or religious beliefs. An alternative reply which has been used defend moral beliefs is that their truth does not consist in their tracking some external state of affairs. Whether or not it is successful in the case of moral beliefs, this reply is less plausible for religious beliefs. So religious beliefs emerge as particularly vulnerable to evolutionary debunking.

Genes are thought to have evolved from long-lived and multiply-interactive molecules in the early stages of the origins of life. However, at that stage there were no replicators, and the distinction between interactors and replicators did not yet apply. Nevertheless, the process of evolution that proceeded from initial autocatalytic hypercycles to full organisms was a Darwinian process of selection of favourable variants. We distinguish therefore between Neo-Darwinian evolution and the related Weismannian and Central Dogma divisions, on the one hand, and (...) the more generic category of Darwinian evolution on the other. We argue that Hull’s and Dawkins’ replicator/interactor distinction of entities is a sufficient, but not necessary, condition for Darwinian evolution to take place. We conceive the origin of genes as a separation between different types of molecules in a thermodynamic state space, and employ a notion of reproducers. (shrink)

Abstract Charles Darwin, in his discussions with Asa Gray and in his published works, doubted whether God could so arrange it that exactly the desired contingent events would occur to cause particular outcomes by natural selection. In this paper, I argue that even a limited or neo-Leibnizian deity could have chosen a world that satisfied some arbitrary set of goals or functions in its outcomes and thus answer Darwin's conundrum. In more general terms, this supports the consistency of natural selection (...) with providentialism, and makes “theistic evolutionism” a coherent position to hold. (shrink)

John Clarke of Hull, one of the eighteenth century's staunchest proponents of psychological egoism, defended that theory in his Foundation of Morality in Theory and Practice. He did so mainly by opposing the objections to egoism in the first two editions of Francis Hutcheson's Inquiry into Virtue. But Clarke also produced a challenging, direct argument for egoism which, regrettably, has received virtually no scholarly attention. In this paper I give it some of the attention it merits. In addition to (...) reconstructing it and addressing interpretive issues about it, I show that it withstands a tempting objection. I also show that although Clarke's argument ultimately fails, to study it is instructive. It illuminates, for example, Hutcheson's likely intentions in a passage relevant to egoism. (shrink)

Bell’s theorem has fascinated physicists and philosophers since his 1964 paper, which was written in response to the 1935 paper of Einstein, Podolsky, and Rosen. Bell’s theorem and its many extensions have led to the claim that quantum mechanics and by inference nature herself are nonlocal in the sense that a measurement on a system by an observer at one location has an immediate effect on a distant entangled system. Einstein was repulsed by such “spooky action at a (...) distance” and was led to question whether quantum mechanics could provide a complete description of physical reality. In this paper I argue that quantum mechanics does not require spooky action at a distance of any kind and yet it is entirely reasonable to question the assumption that quantum mechanics can provide a complete description of physical reality. The magic of entangled quantum states has little to do with entanglement and everything to do with superposition, a property of all quantum systems and a foundational tenet of quantum mechanics.

To naturalize religion, we must identify what religion is, and what aspects of it we are trying to explain. In this paper, religious social institutional behavior is the explanatory target, and an explanatory hypothesis based on shared primate social dominance psychology is given. The argument is that various religious features, including the high status afforded the religious, and the high status afforded to deities, are an expression of this social dominance psychology in a context for which it did not evolve: (...) high-density populations made possible by agriculture. (shrink)

The word 'reason' as used today is used ambiguous in its meaning. It may denote either of two mental faculties: a lower reason associated with discursive, linear thinking, and a higher reason associated with direct apprehension of first principles of mathematics and logic, and possibly also of moral and religious truths. These two faculties may be provisionally named Reason (higher reason) and rationality (lower reason). Common language and personal experience supply evidence of these being distinct faculties. So does classical philosophical (...) literature, the locus classicus being Plato's Divided Line analogy. -/- The effect of currently using a single word to denote both faculties not only produces confusion, but has had the effect of decreasing personal and cultural awareness of the higher faculty, Reason. Loss of a sense of Reason has arguably contributed to various psychological, social, moral, and spiritual problems of the modern age. This issue was also a central concern of 19th century Transcendentalists, who reacted to the radical empiricism of Locke. It would be advantageous to adopt consistent terms that make explicit a distinction between higher and lower reason. One possibility is to re-introduce the Greek philosophical terms nous and dianoia for the higher and lower reason, respectively. This discussion has certain parallels with the recent theories of McGilchrist (2009) concerning the increasingly left-brain hemisphere orientation of human culture. (shrink)

John Searle’s Speech Act Theory enumerates necessary and sufficient conditions for a non-defective act of promising in producing sincere promises. This paper seeks to demonstrate the conjunctive insufficiency of the foregoing conditions due to the inadequacy of the sincerity condition to guarantee predicated acts being fulfillable. Being the definitive condition which contains the psychological state distinct in promises as illocutionary acts, that is the expression of intention (S intends to A), I purport that not all sincere promises are non-defective. (...) To motivate this, I shall explicate Searle’s conception of full blown explicit promises as his basic qualification for the application of the above conditions, and set the line as to how explicit is ‘explicit’? As a response to this insufficiency, I shall propose a condition, as part and parcel of the Propositional Content Clause, that makes up Searle’s felicity conditions for promises, which requires explicitness of the form: “A is fulfillable if A is explicit in form”. A is explicit if and only if 1) A is literal in form, where A can have either 1 basic or multiple meanings, and 2) The meaning of A, whether basic or multiple, with respect to its context is directly stated in the sentence uttered. I call this the Discharge Condition. (shrink)

The meaning of Lorentz contraction in special relativity and its connection with Bell’s spaceships parable is discussed. The motion of Bell’s spaceships is then compared with the accelerated motion of a rigid body. We have tried to write this in a simple form that could be used to correct students’ misconceptions due to conflicting earlier treatments.

This presentation of Aristotle's natural deduction system supplements earlier presentations and gives more historical evidence. Some fine-tunings resulted from conversations with Timothy Smiley, Charles Kahn, Josiah Gould, John Kearns,John Glanvillle, and William Parry.The criticism of Aristotle's theory of propositions found at the end of this 1974 presentation was retracted in Corcoran's 2009 HPL article "Aristotle's demonstrative logic".

We argue that the logical outcome of the cladistics revolution in biological systematics, and the move towards rankless phylogenetic classification of nested monophyletic groups as formalized in the PhyloCode, is to eliminate the species rank along with all the others and simply name clades. We propose that the lowest level of formally named clade be the SNaRC, the Smallest Named and Registered Clade. The SNaRC is an epistemic level in the classification, not an ontic one. Naming stops at that level (...) because there is no currently acceptable evidence for clades within it, not because no smaller clades exist. Later, included clades may be named. They would then become the SNaRCs, while the original SNaRC would keep its original name. We argue that all theoretical tasks of biology, in evolution and ecology, as well as practical tasks such as conservation assessment, are better approached using this rankless phylogenetic approach.

This article compares James M. Buchanan's and John Rawls's theories of democratic governance. In particular it compares their positions on the characteristics of a legitimate social contract. Where Buchanan argues that additional police force can be used to quell political demonstrations, Rawls argues for a social contract that meets the difference principle.

Ontologies, as the term is used in informatics, are structured vocabularies comprised of human- and computer-interpretable terms and relations that represent entities and relationships. Within informatics fields, ontologies play an important role in knowledge and data standardization, representation, integra- tion, sharing and analysis. They have also become a foundation of artificial intelligence (AI) research. In what follows, we outline the Coronavirus Infectious Disease Ontology (CIDO), which covers multiple areas in the domain of coronavirus diseases, including etiology, transmission, epidemiology, pathogenesis, diagnosis, (...) prevention, and treatment. We emphasize CIDO development relevant to COVID-19. (shrink)

John Carvalho’s Thinking with Images, an Enactivist Aesthetics argues that puzzling artworks can draw us into a special activity – thinking when we don’t know what to think – which is valuable because it takes us beyond our skills and understanding. Enactivism is the theory of mind that best explains such thinking. The book illustrates this proposal with four chapters that detail Carvalho’s highly personal or individual encounters with enigmatic works of art. I raise two concerns. First, the four (...) illustrative chapters say that they are enactivist, but they do not show this. The illustrative chapters detail considerations about the works that are not distinguished by a particular theory of mind and might fit with any number of approaches to works of art. The suggestion that the thinking presented in each chapter is skillful is not explained. Second, the book does not just focus on thinking when we don’t know what to think, it also claims that such thinking frees us from mere looking. But enactivism does not require us to deny that our engagement with particular works in their ‘concrete singularity,’ to use Carvalho’s term, is perceptual. If perception is richly integrated or even continuous with what we understand skillfully or cognitively – and enacted in one’s circumstances – this does not erase differences between perception and thought or between their functions. When we ‘think with’ an individual so that we are engaged with it in its concrete singularity, perception is involved either in the present or the past. There is no need to shunt perception or looking aside as life activities that are just rule-bound, just part of knowing what to think rather than part of our response when we don’t know what to think.

A thorough examination of John Wesley’s writings will show that he was not a biblical literalist or infallibilist, despite his own occasional suggestions to the contrary. His most important principles for interpreting the Bible were: We should take its words literally only if doing so is not absurd, in which case we should “look for a looser meaning;” and “No Scripture can mean that God is not love, or that his mercy is not over all his works.” Eleven instances (...) of his not taking biblical texts literally are examined. His real view was something like this: Biblical language is infallibly and literally true if and only if it does not contradict more basic scriptures and is not absurd, that is, not construed literally when metaphorical, or not misleadingly metaphorical, or not oversimplified or exaggerated, or not culture bound, or not contrary to reason and experience, or not ethically unconscionable and unloving.

John Perry has recently developed a form of Compatibilism that respects the Principle of Alternatives (PA), according to which free agency requires having the ability to do more than one thing. Eschewing so-called Frankfurt counterexamples to this intuitively plausible principle, long the bête noire of those who would like to believe in free agency and Determinism, Perry argues that there is an important sense in which we can act differently than we do. It signifies the “natural” property of possessing (...) a latent ability, a notion free of the mysteriousness surrounding accounts of the freedom to do otherwise based on religious or even philosophical considerations, yet sufficient to conceptually ground our assignments of praise and blame. Perry goes on to advise his readers to abandon all such unscientific accounts in favor of his common sense approach. -/- I argue that Perry’s Compatibilism (PC) leads to the same objection as other Humean versions thereof, as well as fails to explain certain intuitions regarding self-control and initiative. I conclude with an assessment of the prospects for his proposed revision of PC, written in light of these concerns. (shrink)

Centuries ago, Descartes and Locke initiated a foundational debate in epistemology over the relationship between knowledge, on the one hand, and practical factors, on the other. Descartes claimed that knowledge and practice are fundamentally separate. Locke claimed that knowledge and practice are fundamentally united. After a period of dormancy, their disagreement has reignited on the contemporary scene. Latter-day Lockeans claim that knowledge itself is essentially connected to, and perhaps even constituted by, practical factors such as how much is at stake, (...) how important the situation is, or how one should act. Latter-day Cartesians claim, by contrast, that knowledge is entirely constituted by truth-related factors such as truth, belief, and evidence. Each side has supported its case with claims about patterns in ordinary behavior and knowledge judgments. Lockeans argue that these patterns are best explained by positing a fundamental and direct link between knowledge and practical factors. Cartesians argue that the patterns can be equally well explained by positing an indirect link, entirely mediated by the traditional factors of truth, belief, and evidence, thereby rendering the Lockean hypothesis unnecessary. We argue that Cartesians are right about some practical factors, in particular stakes and how important a situation is, which have, at best, a modest indirect relationship to knowledge. However, Lockeans are right about actionability: whether a person should pursue a course of action is unquestionably very powerfully and directly connected to knowledge. (shrink)

In his Target Article, Terrence Deacon develops simple models that assist in understanding the role of RNA in the origins of life. However, his models fail to adequately represent an important evolutionary dynamic. Central to this dynamic is the selection that impinges on RNA molecules in the context of their association with proto-metabolisms. This selection shapes the role of RNA in the emergence of life. When this evolutionary dynamic is appropriately taken into account, it predicts a role for RNA that (...) is consistent with the Managed-Metabolism Hypothesis about the origins of life, and inconsistent with Deacon’s account.

In the year 1900, the German philosopher Carl Stumpf made one of the earliest phonograph recordings to document an example of traditional music. The ensemble he recorded was the Siamese Court Orchestra which was performing in Germany at that time. This led to the establishment of the Berlin Phonogramm-Archiv and the beginning of the extensive recording of world traditional music. While written scores have begun to break traditional music away from its dependence on initiation and apprenticeship, the recording of music (...) has had an even more powerful impact on the role of memory in traditional music. No longer is one required to attend a performance, one can simply listen to a recording. Likewise, one can use recordings and videos to learn a piece without the presence of a teacher and can learn the music of another tradition. To consider the future of traditional music, the transformations created by the externalization of memory needs to be examined. This paper hopes to take a step in this direction. It will first consider the psychology of music developed by Stumpf himself. Especially the opposition between the phenomenological reception of music and it’s tempering by the consciousness which allows for aesthetic experience. It will extend this by considering Alain Daniélou’s reflections on the impact of writing and recording on musical creativity. The externalization of memory and the recording of traditional music, leads to may benefits - we have historical records of beautiful musical performances and traditions, many of which have already been lost - but simultaneously this externalization of memory threatens the very essence of traditional and religious music. Finally, the paper will address these paradoxes by applying Jacques Derrida and Bernard Stiegler’s idea of the ‘pharmacon’, and ‘positive pharmacology’ to understand how to navigate these contradictions which face this externalization of musical memory.

Many philosophers claim that interesting forms of epistemic evaluation are insensitive to truth in a very specific way. Suppose that two possible agents believe the same proposition based on the same evidence. Either both are justified or neither is; either both have good evidence for holding the belief or neither does. This does not change if, on this particular occasion, it turns out that only one of the two agents has a true belief. Epitomizing this line of thought are thought (...) experiments about radically deceived “brains in vats.” It is widely and uncritically assumed that such a brain is equally justified as its normally embodied human “twin.” This “parity” intuition is the heart of truth-insensitive theories of core epistemological properties such as justification and rationality. Rejecting the parity intuition is considered radical and revisionist. In this paper, I show that exactly the opposite is true. The parity intuition is idiosyncratic and widely rejected. A brain in a vat is not justified and has worse evidence than its normally embodied counterpart. On nearly every ordinary way of evaluating beliefs, a false belief is significantly inferior to a true belief. Of all the evaluations studied here, only blamelessness is truth-insensitive. (shrink)

Among the most animating debates in eighteenth-century British ethics was the debate over psychological egoism, the view that our most basic desires are self-interested. An important episode in that debate, less well known than it should be, was the exchange between Francis Hutcheson and John Clarke of Hull. In the early editions of his Inquiry into Virtue, Hutcheson argued ingeniously against psychological egoism; in his Foundation of Morality, Clarke argued ingeniously against Hutcheson’s arguments. Later, Hutcheson attempted new arguments against (...) psychological egoism, designed to overcome Clarke’s objections. This article examines the exchange between these philosophers. Its conclusion, influenced partly by Clarke, is that psychological egoism withstands Hutcheson’s arguments. This is not to belittle those arguments—indeed, they are among the most resourceful and plausible of their kind. The fact that egoism withstands them is thus not a mere negative result, but a stimulus to consider carefully the ways in which progress in this area may be possible. (shrink)

In this article I address a puzzle about one of Francis Hutcheson’s objections to psychological egoism. The puzzle concerns his premise that God receives no benefit from rewarding the virtuous. Why, in the early editions of his Inquiry Concerning Virtue (1725, 1726), does Hutcheson leave this premise undefended? And why, in the later editions (1729, 1738), does he continue to do so, knowing that in 1726 John Clarke of Hull had subjected the premise to plausible criticism, geared to the (...) very audience (mainly Christian) for whom Hutcheson’s objection to egoism was written? This puzzle is not negligible. Some might claim that Hutcheson ruins his objection by ignoring Clarke’s criticism. To answer the puzzle we must consider not only Hutcheson’s philosophy but also some theological assumptions of Hutcheson’s time. (shrink)

This chapter explores how our understanding of Molyneux’s question, and of the possibility of an experimental resolution to it, should be affected by recognizing the complexity that is involved in reidentifying shapes and other spatial properties across differing sensory manifestations of them. I will argue that while philosophers today usually treat the question as concerning ‘the relations between perceptions of shape in different sensory modalities’ (Campbell 1995, 301), in fact this is only part of the question’s real interest, and that (...) the answer to the question also turns on how shape is perceived within each of sight and touch individually.

Some of the most forceful objections to William Wollaston's moral theory come from his early critics, namely, Thomas Bott (1688-1754), Francis Hutcheson (1694-1746), and John Clarke of Hull (1687-1734). These objections are little known, while the inferior objections of Hume, Bentham, and later prominent critics are familiar. This fact is regrettable. For instance, it impedes a robust understanding of eighteenth-century British ethics; also, it fosters a questionable view as to why Wollaston's theory, although at first well received, soon faded (...) in esteem among philosophers. This paper gives Wollaston's early critics some of the attention they deserve. It reconstructs some of their objections to Wollaston's philosophy, addresses replies to those objections, and shows that despite some minor flaws, the objections succeed. A fact that becomes clear is that Wollaston's philosophy had suffered devastating criticism years before Hume wrote anything against it. (shrink)

Time in electromagnetism shares many features with time in other physical theories. But there is one aspect of electromagnetism's relationship with time that has always been controversial, yet has not always attracted the limelight it deserves: the electromagnetic arrow of time. Beginning with a re-analysis of a famous argument between Ritz and Einstein over the origins of the radiation arrow, this chapter frames the debate between modern Einsteinians and neo-Ritzians. It tries to find a clean statement of what the arrow (...) is and then explains how it relates to the cosmological and thermodynamic arrows, representing the most developed and sophisticated attack yet, in either the physics or philosophy literature, on the electromagnetic arrow of time.
