Issues with current food systems have been problematised through various lenses, including concerns about the dominance of intensively produced animal-source foods (ASFs) or ultra-processed foods (UPFs) in diets on health, environmental sustainability and/or justice grounds. In this commentary, we argue that there is value in adopting a more common framing and approach for these food systems issues based on the understanding that ASFs and UPFs are interlinked manifestations of financialised food systems prioritising the interests of a select few large corporations (...) and their shareholders. Firstly, we outline some of the common drivers of the proliferation of UPFs and ASFs in current food systems, including a regulatory environment that prioritises the interests of large corporations and financiers above other considerations. Based on ecological regulation theory, we then propose multi-sectoral policy options and collective actions to improve both human and planetary health. These include (but are not limited to): re-orienting agricultural subsidies toward more agroecological operations; prioritising equity-focused measures, such as a universal basic income; land use value taxes; and revitalising competition policy to address agri-food industry consolidation. Implementing the proposed actions will likely require strong coordination and advocacy from various civil society groups. We suggest that a framing centred on financialised food systems may create space for allies to mobilise and effectively draw on collective resources, including public health, food sovereignty alliances, labour unions, farmers, small-scale agri-food businesses and retailers, consumer groups, animal welfare groups, governments without vested interests, and intergovernmental organisations.

I aim to illuminate foundational epistemological issues by reflecting on 'epistemic consequentialism'—the epistemic analogue of ethical consequentialism. Epistemic consequentialism employs a concept of cognitive value playing a role in epistemic norms governing belief-like states that is analogous to the role goodness plays in act-governing moral norms. A distinction between 'direct' and 'indirect' versions of epistemic consequentialism is held to be as important as the familiar ethical distinction on which it is based. These versions are illustrated, respectively, by cognitive decision-theory and (...) reliabilism. Cognitive decision-theory is defended, and various conceptual issues concerning it explored. A simple dilemma suggests that epistemic consequentialism has radical consequences. (shrink)

The function of categories of the human sciences is a well-established field of scholarly inquiry, animated by debates over their capacity to reduce, exclude, determine, abstract, produce, loop, control, and/or restrain. This special issue takes an interdisciplinary perspective to investigate urgent questions about the ‘material force’ of categories as they operate in practice. Specifically, we emphasise the plasticity of categories and how their ambivalent boundaries can render their categorical forcefulness continuously operative. Categories morph and shift as they traverse different fields, (...) re-articulating difference as they interact with divergent institutions and epistemic infrastructures. The five interdisciplinary articles in this issue explore the material force of categories across varied contexts, including the prison system, digital culture, legal frameworks, psychiatric diagnostics, and applied governmental research. In so doing, the special issue as a whole emphasises the capacious yet persistent nature of categorisation, revealing how, in multiple ways, categories can stabilise the management of people precisely through their inherent structures of contingency and ambivalence.

Although many researchers theorize that primitive numerosity processing abilities may lay the foundation for whole number concepts, other classes of numbers, like fractions, are sometimes assumed to be inaccessible to primitive architectures. This research presents evidence that the automatic processing of nonsymbolic magnitudes affects processing of symbolic fractions. Participants completed modified Stroop tasks in which they selected the larger of two symbolic fractions while the ratios of the fonts in which the fractions were printed and the overall sizes of the (...) compared fractions were manipulated as irrelevant dimensions. Participants were slower and less accurate when nonsymbolic dimensions of printed fractions were incongruent with the symbolic comparison decision. Results indicated a robust basic sensitivity to nonsymbolic ratios that exceeds prior conceptions about the accessibility of fraction values. Results also indicated a congruity effect for overall fraction size, contrary to findings of prior research. These findings have implications for extending theory about the nature of human number sense and mathematical cognition more generally. (shrink)

Originally published in 1940, this book contains an expanded English translation of Books 8 and 9 of Aristotle's Nicomachean Ethics. These two books are devoted to a discussion on the nature of friendship and the role it played in Greek life, and Percival supplies an introduction with a background to the subject of ancient friendship prior to Aristotle's formulation. This book will be of value to anyone with an interest in ancient friendship or the philosophy of Aristotle.

Richard Dawkins tries to establish an analogy between computer viruses and theistic belief systems, analyzing the latter in terms of his concept of the meme. The underlying thrust of Dawkins' argument is to downplay the role of truth and logic in the survival of theories and to emphasize humankind's helpless liability to incurable infection by doctrines that Dawkins regards as absurd. Dawkins supplies a list of "symptoms” of mind-infection. However, on closer investigation these characteristics are found to be either rather (...) weak protection against criticism or quite virtuous. Dawkins relies on a crude justificationism that could just as well be called a mind-virus. Applying Dawkins’ own selection of the general characteristics of a good meme protector and propagator leads to the conclusion that his particular theistic examples would actually impair copyability. -/- Scientific theories are better examples of memes with high longevity, fecundity, and fidelity. A Darwinian analysis of wishful and fearful thinking as useful to hypotheses-testing and goal-seeking organisms undermines Dawkins' attribution of absolute irrational stubbornness to theists. To counterbalance Dawkins' emphasis on the propagation of the absurd, I rehabilitate the Socratic emphasis on the importance of truth and logic in rhetoric, interpreted broadly as the theory of the successful propagation of a message. I use Popper's notion of situational analysis, and an evolutionary perspective to argue that rational standards of a message enhance its copyability. I further apply Popper’s notions of World 3, 2, and 1 to memes; this helps us see the perpetuation of a doctrine as a logical task. (shrink)

The traditional conception of knowledge is justified, true belief. If one looks at a modern textbook on epistemology, the great bulk of questions with which it deals are to do with personal knowledge, as embodied in beliefs and the proper experiences that someone ought to have had in order to have the right (or justification) to know. I intend to argue that due to the explosive growth of knowledge whose domain is “outside the head”, this conception has outlived its relevance. (...) -/- On the other hand, Karl Popper’s (1934) Falsificationism, with its emphasis on the objective character of knowledge, is not only a sounder, but also a more appropriate theory of knowledge for understanding the nature and growth of civilization. Later, Popper (1945) generalized this approach to obtain critical rationalism, in which all claims to knowledge, whether scientific or otherwise, are understood as objective solutions to objective problems and can be evaluated by other non-observational - types of criticism. I will first argue that Popper’s methodology is quite suited to the view that knowledge is an objective autonomous product and then adduce his theory of world 3, an ontology that neatly wraps up various considerations. World 3 is the domain of abstract products of the human mind that now have a life of their own, outside of human heads: theories, arguments, problems, plans, etc. I then adduce some other arguments for the autonomous quality of knowledge.

The mathematical study of probability originated in the seventeenth century, when mathematicians were invited to tackle problems arising in games of chance. In such games gamblers want to know which betting odds on unpredictable events are advantageous. This amounts to a concern with probability, because probability and fair betting odds appear linked by the principle that odds of m to n for a bet on a repeatable event E are fair if and only if the probability of E is n/(m (...) + n). For example, suppose E is the occurrence of double‐six on a throw of two dice and that its probability is 1/36 = 1/(35 + 1). Because of the intuitive connection between the probability of an event and its long‐run frequency in repeated trials, we would expect E to occur on average 1 time in (35 + 1) throws. Since to set odds on E at 35 to 1 is to agree that for a stake B, the one who bets on E gains 35B/1 if E occurs and loses B to his opponent if it does not, those must be the fair odds for a bet on E. At them, we can expect 1 win of 35B to be balanced in the long run by 35 losses of the stake B, so that neither party to the bet enjoys net gain. (shrink)

It is one thing for a scientist to speak a language in which he can conduct and communicate his investigations, another for him to possess a reflective understanding enabling him to explain the nature and workings of that language. Many who have sought such an understanding have held that the concepts of “meaning,” “reference,” and “theoretical term” play a crucial role in developing it. But others — instrumentalist skeptics about reference, Quinean skeptics about meaning, and skeptics about the theory/observation distinction (...) — have denied this. (shrink)

This paper is in three sections. In the first I describe and illustrate three uses of indices of truth in semantics. The way I illustrate this classification is not completely uncontroversial, but I expect that my intuitions on this matter are generally shared. In the second section I broach a question which is central to the metaphysics of time, namely: how should certain temporal indices of truth - times - be fitted within this classificatory scheme? I sketch three proposals as (...) to how this might be done, and show how they constitute different metaphysical conceptions of the nature of time. Finally, in the third section I turn to a specific problem with the classification of times (as indices of truth) I call 'non-indexical'. Mellor (1981) thinks this problem insoluble, and argues that it shows this classification to be absurd. However, by appealing to the modal analogues of the issues involved, I first show that Mellor's argument is question- begging, and then go on to show how the non-indexical classification of times might undermine the presuppositions on which his argument rests. The paper attempts to contribute to a discussion of the question raised in section II, not to provide a definitive answer to it. (shrink)

In a brief passage, David Lewis derives from quantum-theory a dilemma regarding the explanation of chance events which he tries to solve by first distinguishing plain from contrastive why-questions have answers. His brevity warrants elaboration and critique. I endorse his derivation, but I make a structural objection to his solution. Once a further distinction is drawn between different kinds of contrastive why-question, his solution can be modified and refined so as to go some way to meeting this objection. However, it (...) cannot resist a deeper objection to the effect that chance events can be given contrastive explanations after all. The alternative solution to the dilemma that I recommend holds Lewis's conception of the 'essence of chance' to be illusory. (shrink)

Clarke and Beck suggest that the ratio processing system may be a component of the approximate number system, which they suggest represents rational numbers. We argue that available evidence is inconsistent with their account and advocate for a two-systems view. This implies that there may be many access points for numerical cognition – and that privileging the ANS may be a mistake.

In a Postscript, David Lewis tries to extend results obtained in his "Time's Arrow and Counterfactual Dependence" from the deterministic case to the indeterministic one. In particular, he claims that under the supposition that the actual world is indeterministic, the truth of the counterfactual 'If Nixon had pressed the button, there would have been a nuclear holocaust' is reconciled with his truth conditions for counterfactual conditionals by a certain refinement of his earlier treatment. Sections II and III explain why his (...) claim is mistaken. Section IV remarks why his matters. (shrink)

Recent research in numerical cognition has begun to systematically detail the ability of humans and nonhuman animals to perceive the magnitudes of nonsymbolic ratios. These relationally defined analogs to rational numbers offer new potential insights into the nature of human numerical processing. However, research into their similarities with and connections to symbolic numbers remains in its infancy. The current research aims to further explore these similarities by investigating whether the magnitudes of nonsymbolic ratios are associated with space just as symbolic (...) numbers are. In two experiments, we found that responses were faster on the left for smaller nonsymbolic ratio magnitudes and faster on the right for larger nonsymbolic ratio magnitudes. These results further elucidate the nature of nonsymbolic ratio processing, extending the literature of spatial–numerical associations to nonsymbolic relative magnitudes. We discuss potential implications of these findings for theories of human magnitude processing in general and how this general processing relates to numerical processing. (shrink)

PaceZagzebski, there is no route from the value of knowledge to a non–reliabilist virtue–theoretic epistemology. Her discussion of the value problem is marred by an uncritical and confused employment of the notion of a “state” of knowledge, an uncritical acceptance of a “knowledge–belief” identity thesis, and an incoherent presumption that the widely held thought that knowledge is more valuable than true belief amounts to the view that knowledge is a state of true belief having an intrinsic property which a state (...) of ‘mere” true belief lacks. Her arguments against a “machine–product” conception of knowledge are undermined by these flaws, while the alternative “agent–act” model she recommends is unattractive, at odds with the knowledge–belief identity thesis she favours, and no solution to the problem of the value of knowledge she poses. I end with the observation that her version of virtue–theoretic epistemology points in the direction of cognitive decision–theoretic norms, and I briefly discuss the bearing of this fact upon her viewpoint.

Philosophy and economics of Malthusianism. An optimistic view of human population growth and a critique of The Club of Rome and Paul R. Ehrlich, author of The Population Bomb. I apply Julian Simon's perspective to the malthusian debate, inspired by his book The Ultimate Resource. When a child is born he brings into existence not just an extra mouth to feed, but two hands and - more importantly in the long run - an extra brain with which to solve any (...) problems that an increase in population brings. In the long run, and given enough freedom, there in a propensity for humans to produce more than they consume. We are not just like flies in a bottle with a limited amount of resources, but creative creatures that can in principle engage in continual, never ending economic growth. -/- More Info: Multiple publishers: National Review; Clashing Views on Controversial Social Issues; Libertarian Alliance, UK.

It’s often claimed that some people—fundamentalists or fanatics—are indeed sealed off from rational criticism. And every month new pop psychology books appear, describing the dumb ways ordinary people make decisions, as revealed by psychological experiments. The conclusion is that all or most people are fundamentally irrational. -/- Ray Scott Percival sets out to demolish the whole notion of the closed mind and of human irrationality. There is a difference between making mistakes and being irrational. Though humans are prone to (...) mistakes, they remain rational. In fact, making mistakes is a sign of rationality: a totally non-rational entity could not make a mistake. -/- Rationality does not mean absence of error; it means the possibility of correcting error in the light of criticism. In this sense, all human beliefs are rational: they are all vulnerable to being abandoned when shown to be faulty. -/- Percival agrees that people cling stubbornly to their beliefs, but he maintains, first, that not being too ready to abandon one’s beliefs is rational, and second, that people do not cling to their beliefs indefinitely or “come what may.” The illusion that they do can be dispelled by examining what really goes on in the formation and abandonment of beliefs, and here we need to observe the high rate of turnover in membership of ideological movements, as well as their numerous splits and schisms. -/- Percival examines and refutes the arguments of writers who have upheld the Irrationality or Closed Mind thesis, including Raymond Boudon, Serge Chakotin, Richard Dawkins, Jon Elster, Ernest Gellner, Adolf Hitler, Leszek Kolakowski, Walter Laqueur, Gustav Le Bon, Karl Popper, and Max Weber. -/- A key aspect of Percival’s approach is to identify “the persuader’s predicament,” the situational logic of the propagandist. Percival contends that a propagandist is faced with a trade-off between his message being closed to criticism and the message reaching and converting as many people as possible. It is possible to make a belief system more closed to criticism, but only by limiting the wide dissemination of the system. Percival illustrates the way belief systems adapt to criticism by an examination of two ideologies, Marxism and Freudianism, and by various examples drawn from the history of religion. (shrink)

For twenty years, D. H. Mellor has promoted an influential defence of a view of time he first called the ‘tenseless’ view, but now associates with what he calls the ‘B-theory.’ It is his defence of this view, not the view itself, which is generally taken to be novel. It is organized around a forcefully presented attack on rival views which he claims to be a development of McTaggart's celebrated argument that the ‘A-series’ is contradictory. I will call this attack (...) ‘Mellor's McTaggart.’ Although it has received much critical attention, it has not been well understood. For one thing, it has changed over the years in a way that is little appreciated. Whereas Mellor's original version amounts to a dilemma each horn of which contains a single strand of argument, later statements of the first horn contain a second strand of argument unannounced. I shall be concerned to disentangle these strands. I shall also show them to have been largely anticipated by Gareth Evans. However, my main aim is not the clarification of Mellor's McTaggart, but its refutation. I shall show that there is a rival to Mellor's view of time against which the first horn of the dilemma begs the question both as originally presented, and as supplemented. This rival is a ‘Priorean’ version of the ‘presentist’ doctrine that only what is present exists. Although Prior himself gave McTaggart's own argument short shrift, in refuting Mellor's development of it I do not merely resurrect Prior's moves. Mellor's McTaggart introduces specifically semantic considerations. It focuses not as McTaggart did on presentness and futurity etc., but on the truth-values of tokens of propositions in which presentness and futurity etc. are ascribed. Consequently, its refutation requires an answer, from the perspective of a presentist metaphysics, to a question which came to the fore only after Prior's death. The question is this: How should semantic theory be developed in the light of the need for a theory of linguistic understanding? Though Evans flirted with the issue of how this question should be answered from a presentist perspective, the answer he articulates is wrong. I shall do no more than sketch the correct answer. That is all a refutation of Mellor's McTaggart requires. (shrink)

Confirmation and falsification are different strategies for testing theories and characterizing the outcomes of those tests. Roughly speaking, confirmation is the act of using evidence or reason to verify or certify that a statement is true, definite, or approximately true, whereas falsification is the act of classifying a statement as false in the light of observation reports. After expounding the intellectual history behind confirmation and falsificationism, reaching back to Plato and Aristotle, I survey some of the main controversial issues and (...) arguments that pertain to the choice between these strategies: the Raven Paradox, the Duhem/Quine problem and the Grue Paradox. Finally, I outline an evolutionary criticism of inductive Bayesian approaches based on my assumption of doxastic involuntarism. (shrink)

The question as to whether some objects are possible worlds that have an initial segment in common, i.e. so that their fusion is a temporal tree whose branches are possible worlds, arises both for those who hold that our universe has the structure of a temporal tree and for those who hold that what there is includes concrete universes of every possible variety. The notion of “possible world” employed in the question is seen to be the notion of an object (...) of a kind such that objects of that kind play a certain theoretical role. Lewis’s discussion of the question is thereby clarified but is nevertheless inadequate; his negative answer is correct but even from his combinatorialist viewpoint the rationale he provides for this answer is misguided. I explain why the combinatorialist advocate of concrete plenitude should hold that no object is a tree of possible worlds. Then I explain that for a different reason the nomic essentialist advocate of concrete plenitude should hold this much too. (shrink)
