In its classical conception, game theory aspires to be a determinate decision theory for games, understood as elements of a structurally specified domain. Its aim is to determine for each game in the domain a complete solution to each player's decision problem, a solution valid for all real-world instantiations, regardless of context. "Permissiveness" would constrain the theory to designate as admissible for a player any conjecture consistent with the function's designation of admissible strategies for the other players. Given permissiveness and (...) other appropriate constraints, solution sets must contain only Nash equilibria and at least one pure-strategy equilibrium, and there is no solution to games in which no symmetry invariant set of pure-strategy equilibria forms a Cartesian product. These results imply that the classical program is unrealizable. Moreover, the program is implicitly committed to permissiveness, through its common-knowledge assumptions and its commitment to equilibrium. The resulting incoherence deeply undermines the classical conception in a way that consolidates a long series of contextualist criticisms. (shrink)

Recent years have witnessed an increasing number of attempts to reconstruct Marxian theory in forms that can be assessed by reference to currently received standards in various disciplines. The work has even been said to establish a new paradigm: “analytical Marxism.” One doesn't have to endorse this claim to recognize a good deal of merit in the work. Through creative application of state-of-the-art methods to traditional Marxian issues, researchers have promoted productive cross-fertilization with non-Marxian programs and have revealed many problems (...) that must be resolved for fruitful development of Marxian theory. Marx's work can be relevant to today's problems only if it is examined from vantage points provided by subsequent scientific and philosophical achievements. Moreover, critical engagement with the best science of the day has been an essential part of the Marxian theoretical project from the beginning. (shrink)

Marx criticized political economy for propounding an inverted, mystical view of economic reality. But he went beyond asserting the falsity and apologetic character of the doctrine to characterize it as reflecting a social practice of inversion or mystification — an inverted social world — in which individuals incorporate their own actions into a process whose dynamic lies beyond their control. Caught up in this process, individuals confront aspects of their own agency in the alien or reified form of a given, (...) determining reality. Marx leaves unclear exactly how the process exerts and maintains its hold on agents, the nature of the reasons they might have for wanting to free themselves of it, and under what conditions they could do so. However, it is possible to abstract somewhat from Marx's specific concerns and to model a self-reproducing practice of reification that works through the informational environment of decision. Though of wider interest, this more general conception can shed light on the nature and critique of Marx's inverted world. It draws on conceptual resources from decision theory, game theory and general equilibrium theory. (shrink)

This working paper uses the works of philosophers like Hegel, Marx, and Rawls to explore political philosophy and estrangement.

Edible insects are a potentially less burdensome source of proteins on the environment than livestock for a majority of rural consumers. Hence, edible insects are a timely idea to address the challenges of the supply side to sustainably meet an increasing demand for food. The objective of this paper is twofold. The first is to identify and compare rural-households’ intentions to consume insect-based foods among households drawn from two regions in Kenya—one where consumption of insects is common and the other (...) where the practice is uncommon. The second is to explore consumers’ trust in sources of information regarding quality and appropriateness of food items. The study employed an extended theory of planned behaviour and involved 432 participants. Results indicate that rural households have positive intentions to consume insect-based foods and those intentions are higher for individuals who are more familiar with the practice. Results also show that information sources from industry are more trusted than those from the media. Further, the study revealed that control variables such as perceived availability of insect-based foods and their level of fit with the culinary practices have a higher influence on consumption intentions than general attitudes. In addition, age of the respondent, gender, household size and level of formal education, significantly influence the consumption intentions. The study discusses the implications of these findings in the development of sustainable agri-food systems. (shrink)

In his book, Wizard of the Crow ( 2007 ), the renowned Kenyan novelist, Ngugi wa Thiong’o, expresses the view that a successful society is only guaranteed when women issues are well settled. In light of post-colonial Africa and the era of COVID-19, African women – like the biblical Miriam, the co-liberator with Moses and Aaron (Mi 6:4) – are seen as Nyawiras (plural for Nyawira, the hardworking woman), as their critical role in preserving the family and society is evident. (...) While relying on a critical review of wa Thiong’o’s works and in engaging a selected religio-cultural literature, the article seeks to explore the role of African women [ Nyawiras ] in societal sustenance. With postcolonial Africa encountering a hotchpotch of challenges, are Nyawiras the best suited persons to deconstruct the status quo and eventually reconstruct the ‘sick’ society under greedy-grabbing male-leaders of nation-states (Aburirias) that have lost their moral compasses? Are women best suited to bring back sanity; and have they crossed the Rubicon in the 21st century? In drawing from diverse examples from Africa and beyond, the research article will be significant in helping the modern African society understand the myriad of problems they are facing in the local and global scene, and eventually appraise women’s heroine roles. Contribution: This research uses a multi-disciplinary approach and engages a dialogue between African literature and Africa’s religio-cultural discourses in order to better understand the complex situation facing Africa.

Some historians have always erred in ignoring oral history methods, as it is always assumed wrongly that the only reliable and trustworthy source of history is the written word. The aim of this article is to underscore the nature and significance of oral histories, which rely on the memory of the narrators. In the case of both Ngugi wa Thiong’o’s and Wole Soyinka’s literary works, their respective childhood experiences are well captured, as they employ both the use of postcolonial and (...) autobiography theories in their theoretical frameworks. In its methodology, this article relied heavily on extensive literature review, oral interviews and archival sources. In seeking to demonstrate the significance of oral history for the preservation of memory and for the writing of history in Africa, the author intends to build from both the above literary works and other theohistorical materials so as to convey the message that the methodology used in chronicling East African oral history, the history of Christian doctrines, Church history or social histories will require us to go beyond postcolonial theory and the theory of autobiography in order to harvest the rich and forward-moving historiographies that remain unexplored and/or unpublished altogether. Contribution: Memory as a critical tool that moves humanity forward is the main subject of this article. The article is relevant to the journal HTS Teologiese Studies/Theological Studies and the world of scholarship as it undertakes a multidisciplinary approach in engaging literary works with theo-historical works in order to build the case for oral techniques in modern scholarship.

The brain for Galen is the ηγεμOνiÓνand ãOΧηof the nervous system. Anatomical demonstration enabled him to advance his claims for its nervous function. His conception of the brain and the nerves hinges on his employment of some psychic pneuma. Galen's system of pneumatic physiology is, however, largely dependent on the demonstration of a functioning vascular system. This paper focuses on two vascular structures-essential for the proper functioning of the brain and nerves-which carry the psychic pneuma. They arc the retiform plexus, (...) or rete mirabile, and the choroid plexuses. The former is a well-established arterial structure at the base of the brain in some higher mammals ; the latter is a vascular plexus in the ventricles of the brain. Taken together, the account Galen gives of these structures is both internally consistent and convincing and sheds useful light on Galen's understanding of the brain and the nerves. (shrink)

This paper advances the thesis that sensory concepts have as a semantic component the first-person indexical. It is argued that the private nature of our access to our own sensations forces, in our talking about them, an indexical reference to the inner states of the speaker in lieu of publicly accessible properties by which reference is usually fixed. Indexicals, such as ‘here’, can be understood despite ignorance of their referent. Such is the case with sensory terms. Furthermore, the thesis that (...) sensory terms are indexical has considerable explanatory power. I give two examples: firstly, I argue that clashes of intuition over Block's ‘inverted spectrum’ thought experiment can be explained by appeal to semantic properties of indexicals. Secondly, I argue that multiple realisability intuitions can be shown to be consistent with the view that sensations are type-identical with brain states. (shrink)

The aim is to provide a theory of consciousness, and of the relation of consciousness through perception with the World. Consciousness is not a mystery, being an internal state analysable into internal constituents. However, it is essentially directed to the World, and this necessitates some knowledge of the World. Certain epistemological powers are peculiar to it, but are they essential? It emerges that consciousness necessitates an accessible perceptual attentive capacity. This is demonstrated through appeal to the principle: the conscious are (...) ‘in touch with’ Reality, and are of necessity oriented towards the truth. Part of the proof turns upon the theory that perception is the sheer presence to awareness of extensionally given phenomenal objects. It contacts objects, not propositions. This is accomplished through the mediation of perceptual ‘proxies’ like side, surface, and ultimately also in seeing through light and visual sensations. However, even prior to this encounter, a ‘The Visual Given’ is presented to consciousness, a causal posit necessitated by the presence of mental causation in the aetiology of the visual experience. This is where the ‘journey’ of the Attention begins, and it ends in Physical Reality, in a complex mental perceptual‐cognitive phenomenon in which in humans the conceptual powers of the mind are engaged in constituting the physical object and its universal setting. Consciousness has from the start an appointment in the concrete with the World in its ultimate physical form, and the introduction sets out to explain how it is that it keeps that appointment.

Many current neurophysiological, psychophysical, and psychological approaches to vision rest on the idea that when we see, the brain produces an internal representation of the world. The activation of this internal representation is assumed to give rise to the experience of seeing. The problem with this kind of approach is that it leaves unexplained how the existence of such a detailed internal representation might produce visual consciousness. An alternative proposal is made here. We propose that seeing is a way of (...) acting. It is a particular way of exploring the environment. Activity in internal representations does not generate the experience of seeing. The out- side world serves as its own, external, representation. The experience of seeing occurs when the organism masters what we call the gov- erning laws of sensorimotor contingency. The advantage of this approach is that it provides a natural and principled way of accounting for visual consciousness, and for the differences in the perceived quality of sensory experience in the different sensory modalities. Sev- eral lines of empirical evidence are brought forward in support of the theory, in particular: evidence from experiments in sensorimotor adaptation, visual “filling in,” visual stability despite eye movements, change blindness, sensory substitution, and color perception.

Additional arguments for sense‐data begin by defending the claim that perceptual sensations are psychological individuals, examples being phosphenes, after‐images, and the ‘ringings’ of ‘tinnitus’. Five arguments for sense‐data follow. First, that since corresponding to every veridical visual field is a possible non‐veridical visual field of sensations, the latter merely needs a different and regular outer cause to be deemed veridical. Second, since bodily sensation experience is extremely strong evidence for the existence of a matching sensation cause, the experience of ‘ringing’ (...) must be strong evidence that a ‘ringing’ sensation is its cause, and this holds in the veridical hearing of a ringing sound. Third, that it is inconceivable that one has a truly visual experience of a red visual field, and absolutely nothing red‐looking be there before one had noticed. Fourth, that the experience of sound might have had a different developmental history, in which first there was merely experience of auditory sensation, and then over millennia such experience gradually found itself caused by regular outer phenomena, thereby constituting the hearing of sound. And a fifth argument that resembles the first argument. (shrink)

In this essay, we explore a fresh avenue into mind-body dualism by considering a seemingly distant question posed by Frege: "Why is it absurd to suppose that Julius Caesar is a number?". The essay falls into three main parts. In the first, through an exploration of Frege’s Julius Caesar problem, we attempt to expose two maxims applicable to the mind-body problem. In the second part, we draw on those maxims in arguing that “full blown dualism” is preferable to (...) more modest, property-theoretic, versions. Finally, in the third part we close by suggesting that full blown dualism need not be spooky, resurrecting a broadly Lockean, rather than Cartesian, metaphysical picture. (shrink)

The most important clarification we bring in our reply to commentators concerns the problem of the “explanatory gap”: that is, the gulf that separates physical processes in the brain from the experienced quality of sensations. By adding two concepts (bodiliness and grabbiness) that were not stressed in the target article, we strengthen our claim and clarify why we think we have solved the explanatory gap problem, – not by dismissing qualia, but, on the contrary, by explaining why sensations have a (...) “feel” and why “feels” feel the way they do. We additionally clarify our views on: internal representations (we claim internal representations cannot explain why sensation has a feel), on behaviorism (we are not behaviorists), on perception and action (we believe there can be perception without action), and on the brain (we believe the brain does do something important in perception).

In this country, we tend to look at Wittgenstein in a rather ahistorical way. We see his concerns as fundamentally logico-linguistic, following on first from the work of Frege and Russell, and then referring back indirectly to the concerns of the British empiricists, to those of Locke and Hume, say, on such matters as the reference of our talk about sensations and scepticism about the external world. Recently there has been considerable discussion of the extent to which Wittgenstein's own analysis (...) of the private language and of rule-following might not itself be a new version of a fundamentally Humean scepticism: according to Saul Kripke, Wittgenstein's arguments amount to a demonstration that there is no more reason for speakers of a language to follow the rules governing the concepts of that language in the same way than on the Humean account there is any reason for an effect to follow its causes.

In lieu of an abstract, here is a brief excerpt of the content:Hume's Missing Shade of Blue Re-viewed John 0. Nelson It is obviously important for Hume's purposes in the Treatise to maintain that simple ideas are always founded in precedent, resembling impressions;1 andhe explicitly, overandover, doesso, evensometimes being so carried away by this first principle ofhis science of man (T 7) or so careless as to say that not just all simple ideas but all ideas are founded in precedent, (...) resembling impressions. At the same time, as often noted, Hume explicitly maintains that it is possible for there to be a simple idea having no precedent, corresponding impression. He argues: There is however one contradictory phaenomenon, which may prove, that 'tis not absolutely impossible for ideas to go before their correspondent impressions... Suppose... a person to have enjoyed his sight for thirty years, and to have become perfectly well acquainted with colours of all kinds, excepting one particular shade of blue... Let all the different shades of that colour, except that single one, beplac'd before him... Now Iask, whether 'tis possible for him, from his own imagination, to supply this deficiency, and raise up to himselfthe idea ofthat particular shade, tho' it had never been conveyed to him by his senses? I believe there arefew but will be ofopinion that he can; and this may serve as a proof, that the simple ideas are not always derived from the correspondent impressions. (T 5) Nowjust prior to this concession (as Cummins calls it ), Hume has said that the full examination ofthis question [the causal relationship between ideas and impression] is the subject of the present treatise; and therefore we shall here content ourselves with establishing one general proposition, That all our simple ideas in their first appearance are deriv'd from simple impressions, which are correspondent to them, and which they exactly represent. (T 4) Volume XV Number 2 353 JOHN O. NELSON And just after the same concession, that a simple idea may be raised up which does not have a prior, correspondent impression, Hume says that it still remains true, that all our simple ideas proceed either mediately or immediately, from their correspondent impressions (T 7). Thus we have Hume explicitly asserting, it seems, both that all simple ideas have precedent correspondent impressions and that they do not. But this, on the face ofit, is an arrant contradiction! Can Hume have Homerically nodded? We have been quoting from the Treatise, but Hume makes the very same contradictory-seeming claims in the Enquiryl A thinker of Hume's acumen might nod for a page or two's quarter hour but not for all of nine years! Moreover, in both places Hume refers to the phenomenon of the impression-less idea ofblue as a contradictory phenomenon, indicating clearly enough that he was himself aware of there seeming to be an inconsistency here in his contentions. What can possibly be going on? Is Hume deliberately being paradoxical? Perhaps trying, for sensation's sake, to shock the reader and so increase sales of his work, as some commentators in the past might have wished to say? But this would be at the expense ofhis own contentions and principles and not the reader's, and not even Hume's bitterest foes and most malicious critics — so far as I know — have ever proposed that Hume would, figuratively speaking, like Oedipus, gouge out his own eyes, even in order to increase sales of the Treatise, nor does it make the slightest sense to think he would. The mystery deepens when we remember that Hume has said, in defining the program of the Treatise, that his intention is to establish the one general proposition that all our simple ideas in their first appearance are deriv'd from simple impressions, which are correspondentto them (T4). What astrange way, we want to exclaim, to show that all our simple ideas are derived from correspondent simple impressions by almost immediately afterwards arguing that it is possible to have an idea that has had no correspondent, precedent impression! Such an egregious nonsequitur mightbe expected ofan absolutely incompetent beginner in philosophy, but we are speaking of David Hume, generally recognized as the profoundest and most acute of...

A curious irony hangs over the two similes of the lantern and the clepsydra which Empedocles used to describe his theories of seeing and breathing. Similes were a feature of Empedocles' style, and it is clear that on these two in particular he has lavished considerable care. They have been preserved in their entirety, as almost the longest continuous quotations which Aristotle makes from any author. Despite such auspicious beginnings, these two similes have proved peculiarly resistant to modern attempts at (...) interpretation. The reason for this, I shall try to show, is that certain features in the two similes took on a spurious significance as a result of Plato's remodelling of Empedocles' theories. Difficulties of interpretation have been caused by trying to read back these innovations of Platonic theory into details of the similes that in their original context were fortuitous and inessential.In Plato vision occurs when fire leaves the eye and joins fire outside to form a single compacted body, along which movements from the visible object are communicated as sensations to the eye.According to Theophrastus, Empedocles explained vision as the result of effluences which are given off from objects and enter the appropriate pores of the eye. Dark effluences enter the watery pores of the eyes, and bright effluences enter the fiery pores of the eye. As I have tried to show in an earlier article, Empedocles distinguished good and bad vision, by day and by night, for eyes with a predominance of fire and for eyes with a predominance of water. Good vision results when the dark and light elements which enter the eye are equally balanced. Poor vision results either when there is too much fire in the eye, so that we are dazzled, or when there is too much water in the eye, so that our vision is dimmed. In the whole of his detailed and one would have thought exhaustive account, Theophrastus says nothing about fire leaving the eye as a factor in the act of vision. (shrink)

The purpose of this book is to lay to rest "fruitless controversy over mind and body" by developing a comprehensive theory of mind. The theory Matson argues for is mind-body identity. In developing his position he takes a hard materialist line: "... if sensations are brain processes then they cannot be... anything else." Yet, he asks, "What is the sentience? Why is there any such phenomenon? What difference does it make?" Rejecting dualism, he steers his materialist identity theory between two (...) mires: epiphenomenalism and behaviorism. His contention is that while sensations are brain processes, man is a sentient being and that sentience makes a difference. The difference sentience makes allows us to say that man is not a machine and is free. (shrink)

A theory of sense‐data is defended, which takes its cue from light. It is that the visual perception of outer physical objects is noticing visual sensations set in two‐dimensional body‐relative physical space, which stands in non‐deviant causal relation to outer phenomenal causes. The first leg of the argument is that there exist regular causally sufficient bodily conditions for the existence of a visual field of given colour‐bright spatial character, quite irrespective of the outer causes of those bodily causes. Now if (...) those bodily conditions were caused by piecemeal scientific intervention we would deem the resulting visual field a psychological existent of type, visual sensations. Since they are also satisfied when the bodily conditions are caused by outer visibles, the same set of sensations must occur in perception of outer items. The theory is defended against the claim that the visual field has no separate existence from our awareness of it, through showing that the criteria for the content of visual field and of visual impression ensure divergence of content. Finally, an explanatorial argument is proposed for the view that sensations generally are psychological individuals, and are not to be understood as merely the internal objects of awareness‐experiences.

Like no other philosopher of this century, the late Yves R. Simon grappled with philosophical issues that still carry weight today. This collection of his essays explores an impressive range of genuinely foundational topics of philosophical inquiry. These essays discuss, among other topics, the relationship between faith and reason, the nature of sensation, and the various meanings of work. SimonOs significant contribution to philosophy through these varied essays is unquestionable, and this is the first such collection of his works.
