Abstract:In this paper, I evaluate the possibility of convergence between animal welfare and environmental ethics. By surveying the most prominent views within each of these respective camps, I argue that animal welfare ethics and ecological theories in environmental ethics are incommensurable in virtue of their respective individualistic and holistic value theories. I conclude by arguing that this conceptual clarification allows us to see that animal welfare ethics can nevertheless be made commensurable with theories in environmental ethics according to which value (...) primarily resides in individuals, rather than in collectives and communities.

This paper considers the use that Plato makes of the Principle of Non-Contradiction in his engagements with eristic refutations. By examining Plato’s use of the principle in his most detailed engagements with eristic—in the Sophist, the discussion of “agonistic” argumentation in the Theaetetus, and especially the Euthydemus—I aim to show that the pressure exerted on Plato by eristic refutations played a crucial role in his development of the PNC, and that the principle provided him with a much more sophisticated means (...) of demarcating philosophical argumentation from eristic than he is generally thought to have. In particular, I argue that Plato’s qualified formulation of the PNC restricts the class of genuine contradictions in such a way that reveals the contradictions that eristics produce through their refutations to be merely apparent and that Plato consistently appeals to his qualified conception of genuine contradiction in his encounters with eristics in order to demonstrate that their refutations are merely apparent. The paper concludes by suggesting that the conception of genuine contradiction afforded by the PNC did not just provide Plato with a way of demarcating genuine from eristic refutations, but also with an answer to substantive philosophical challenges that eristics raised through their refutations.

In this book, Matthew Duncombe argues that Plato, Aristotle, certain Stoics, and Sextus Empiricus each held a broadly "constitutive" view of relativity. According to constitutive accounts, a "relative" is constituted by the relation that it bears to its "correlative". Such treatments of relativity sharply contrast with more familiar nonconstitutive accounts, according to which standing in some relation suffices for being a relative. On such a view, versions of which many scholars have assumed to be at work in antiquity, Alcibiades counts (...) as a relative because he is related to Socrates through the "is more beautiful than" relation.

THIS PAPER CONCERNS A CONTROVERSY about priorities between J. D. Forbes, Professor of Natural Philosophy at the University of Edinburgh, and the noted Swiss scientist Louis Agassiz, later to be a distinguished teacher at Harvard. Its origins lie in the visit which Forbes made at Agassiz' invitation to the Unteraar glacier in Switzerland, in the summer of 1841, during which a major topic of interest was their observations of the bandes bleues, markings in the ice previously little discussed. Both men, (...) in independent later publications, were to establish the importance of the bandes in the theory of glacial ice and its movement. The question of credit for the discovery, and priority in its publication, was unclear at the time and has remained so despite bitter debate. Examination of surviving papers in Great Britain and in Switzerland suggests that previous discussions have not closed the question,' and our purpose is to review the evidence and if possible to clarify the issue.

Why are some people more mentally able than others? In an authoritative, critical and intergrated series of review essays Professor Ian Deary inquires after the cognitive and biological foundations of human mental ability differences. Many accounts of intelligence have examined the structure and number of human mental ability differences and whether they can predict sucess in education,work and social life. Few books have taken psychometric intelligence differences as a starting point and brought together the reductionistic attempts to explain them.New to (...) the highly acclaimed Oxford Psychology Series, Looking Down on Human Intelligence appraises the search for the origins of psychometric intelligence differences in terms of brain function parameters. The book provides an original and thought provoking guide to ancient and modern research on one of the most compelling questions in human psychology. (shrink)

In this paper, I assume, perhaps controversially, that translation into a language of formal logic is not the method by which mathematicians assess mathematical reasoning. Instead, I argue that the actual practice of analyzing, evaluating and critiquing mathematical reasoning resembles, and perhaps equates with, the practice of informal logic or argumentation theory. It doesn’t matter whether the reasoning is a full-fledged mathematical proof or merely some non-deductive mathematical justification: in either case, the methodology of assessment overlaps to a large extent (...) with argument assessment in non-mathematical contexts. I demonstrate this claim by considering the assessment of axiomatic or deductive proofs, probabilistic evidence, computer-aided proofs, and the acceptance of axioms. I also consider Jody Azzouni’s ‘derivation indicator’ view of proofs because it places derivations—which may be thought to invoke formal logic—at the center of mathematical justificatory practice. However, when the notion of ‘derivation’ at work in Azzouni’s view is clarified, it is seen to accord with, rather than to count against, the informal logical view I support. Finally, I pose several open questions for the development of a theory of mathematical argument. (shrink)

The role of dispositions in the physical world is considered. It is shown that not only can classical physics be reasonably construed as the discovery of real dispositions, but also quantum physics. This approach moreover allows a realistic understanding of quantum processes.

Examining the role of dispositions (potentials and propensities) in both physics and psychology reveals that they are commonly derivative dispositions, so called because they derive from other dispositions. Furthermore, when they act, they produce further propensities. Together, therefore, they appear to form discrete degrees within a structure of multiple generative levels. It is then constructively hypothesized that minds and physical nature are themselves discrete degrees within some more universal structure. This gives rise to an effective dualism of mind and nature, (...) but one according to which they are still constantly related by causal connections. I suggest a few of the unified principles of operation of this more complicated but universal structure. (shrink)

The original comic version of T'Challa is a traditional monarch, whose actions demonstrate his concern for maintaining power and securing his nation. In fact, with his strategic use of violence, his demonstrations of empathy and humanity, and his embrace of religious symbolism, T'Challa was classically “Machiavellian” in the comics. "Panther's Rage" chronicles T'Challa's return to Wakanda after an extended stay in the United States as a costumed superhero, most notably with the Avengers. Machiavelli would approve of T'Challa's embrace of violence. (...) Machiavelli was keenly aware of how a ruler should be perceived by his subjects, suggesting that a successful ruler will appear to possess five key qualities that meet with the approval of his subjects: mercy, faith, honesty, humanity, and religion. T'Challa is never as cruel as some of Machiavelli's models, but he does preserve his divinely ordained kingdom by employing fear and religion to stay in power. (shrink)

The causal closure of the physical world is assumed everywhere in physics but has little empirical support within living organisms. For the spiritual to have effects in nature, and make a difference there, the laws of physical nature would have to be modified or extended. I propose that the renormalized parameters of quantum field theory (masses and charges) are available to be varied locally in order to achieve ends in nature. This is not adding extra forces to nature but rescaling (...) the forces which already exist. We separate metric time in 4 dimensions from process time as the order of actualization of potentialities. This is to allow iterative forward and reverse steps in metric time to influence intermediate variations in the vacuum permittivities to move charged bodies towards achieve specific targets at a later time. Then mental or spiritual influx could have effects in nature, and these should be measurable in biophysics experiments. With this proposal, we see after some centuries how ‘final causes’ could once again be seen active in nature. (shrink)

Last year, we reported a new mechanism of DNA replication in mammals. It occurs inside mitochondria and entails the use of processed transcripts, termed bootlaces, which hybridize with the displaced parental strand as the replication fork advances. Here we discuss possible reasons why such an unusual mechanism of DNA replication might have evolved. The bootlace mechanism can minimize the occurrence and impact of single‐strand breaks that would otherwise threaten genome stability. Furthermore, by providing an implicit mismatch recognition system, it should (...) limit the occurrence of replication‐dependent deletions and insertions, and defend against invading elements. Such a mechanism may also limit attempts to manipulate the mammalian mitochondrial genome. (shrink)

In order to link fine-tuning in physics with spiritual influx, I propose that the highest degree in physics is where ‘ends’ are received in physics. By ends, I refer to what it is that determines the means or causes in physics, and what it is that manages or influences to basis parameters (masses and charge values) of the quantum fields. This is fine-tuning, in the sense that it occurs not just for the whole universe (in the Big Bang, for example), (...) but locally. That is, this fine-tuning is different at each time, and in point in space. Thus this influx can be specific to living organisms, and can occur at all the needed scales and levels in psychology and biology, namely every day and every micros-second of our lives. (shrink)

Which way does causation proceed? The pattern in the material world seems to be upward: particles to molecules to organisms to brains to mental processes. In contrast, the principles of quantum mechanics allow us to see a pattern of downward causation. These new ideas describe sets of multiple levels in which each level influences the levels below it through generation and selection. Top-down causation makes exciting sense of the world: we can find analogies in psychology, in the formation of our (...) minds, in locating the source of consciousness, and even in the possible logic of belief in God.

This year is the 300th anniversary of the birth of Emanuel Swedenborg (1688 - 1772). Although he worked in the eighteenth century, his investigations into the nature of physical, physiological and spiritual processes are still relevant today, although they are not as widely known as they deserve. In this article, I will briefly describe the stages in Swedenborg's life, and outline his mature teachings with particular relevance to what is relevant to the concerns of contemporary science, and to the concerns (...) of those wishing to extend that science.

Written by experts in the field, this volume presents a comprehensive investigation into the relationship between argumentation theory and the philosophy of mathematical practice. Argumentation theory studies reasoning and argument, and especially those aspects not addressed, or not addressed well, by formal deduction. The philosophy of mathematical practice diverges from mainstream philosophy of mathematics in the emphasis it places on what the majority of working mathematicians actually do, rather than on mathematical foundations. -/- The book begins by first challenging the (...) assumption that there is no role for informal logic in mathematics. Next, it details the usefulness of argumentation theory in the understanding of mathematical practice, offering an impressively diverse set of examples, covering the history of mathematics, mathematics education and, perhaps surprisingly, formal proof verification. From there, the book demonstrates that mathematics also offers a valuable testbed for argumentation theory. Coverage concludes by defending attention to mathematical argumentation as the basis for new perspectives on the philosophy of mathematics. ​. (shrink)

Modern physics has cast doubt on Newton's idea of particles with definite properties. Do we have to go back to Aristotle for a new understanding of the ultimate nature of substance? If we ask, `what is the nature of substance?', we might be told that this substance is salt, that one is copper, or that the atomic nucleus is a mixture of protons and neutrons. But what are all these substances? What do they have in common which makes them substances? (...) We don't seem to think that such things as colours, numbers, or shapes are by themselves `substantial enough' to be substances in their own right. We therefore change our question to `what is it to be a substance?', or to `what is the ultimate nature of the simplest substances?'. (shrink)

Many of us these days sense there is something real beyond the scope of naturalistic science. But what? Must mental and religious lives always remain a mystery and never become part of scientific knowledge? In this well-argued book, physicist Ian Thompson makes a case for a 'scientific theism'. He shows how a following of core postulates of theism leads to novel and useful predictions about the psychology of minds and the physics of materials which should appear in the universe. These (...) predictions constitute a kind of 'theistic science'. It meshes surprisingly well with the structure of reality already revealed by modern quantum field theory and by theories of developmental stages in human minds. The result is a serious look at a promising new rational structure encompassing theology, psychology and physics. (shrink)

In this article I will suggest that futures are made as embodied enactments of individuals and collectives. Values and identities are shaped as postures, gestures, movements, and expressions that are in themselves sites of personal and communal meaning. Bodily organizations are ground for senses of self, and the recognition, and reaction to, the otherness of others. Bodily organizations are shaped in encounters in families and social and cultural institutions that they in turn shape. Kinds of bodies and kinds of bodily (...) enactments are cultivated in different communities. They can be sources of conflict or sources of transindividual and transcultural becoming. In this article I look at some ways bodily meanings are developed in both families and communities. I use the image of Paladin, a fictional television gunslinger character in the 1950s, among others, to describe processes of embodied self-formation that are derived from the media and other extra-familial sources. I look at the polycultural organization of individual psyches in our era, as well as somatically based community conflict and collaboration. I briefly describe how practiced experiences of somatic organization can be used as tools for personal and communal exploration of new possibility. (shrink)

Discussing questions concerning quantum physics and spirituality together is particularly valuable in order to see the connection between them from a New Church standpoint. An urgent reason for discussing this link is that some people want to identify these things. The feeling is widespread that somehow they are connected, but some “new age” people want to say that quantum physics tells us about spirituality. We know from Swedenborg that the connection is not quite so simple, so we need to understand (...) in more detail what is going on. (shrink)

The analysis of dispositions is used to consider cases where the effect of one disposition operating is the existence of another disposition. This may arise from rearrangements within aggregated structures of dispositional parts, or, it is argued, also as stages of derivative dispositions within a set of multiple generative levels. Inspection of examples in both classical and quantum physics suggests a general principle of `Conditional Forward Causation': that dispositions act 'forwards' in a way conditional on certain circumstances or occasions already (...) existing at the `later' levels.

In cognitive psychology there appears to be a creative tension between models that use connections of a network, and models that use rules for symbol manipulation. The idea of a connectionist network goes back to McCulloch & Pitts [1943] and Hebb [1949], and finds recent revival in the `parallel distributed processing' (PDP) models that have been extensively examined in the last few years (see e.g. Rumelhart et al. [1986]). In the intervening years, however, the predominant explanations of psychology have been (...) in terms of rules for the manipulation of symbolic structures (e.g. since Newell & Simon [1963]). Because of the tension between these different approaches (see e.g. Fodor & Pylyshyn [1988]), there is great interest in the formulation of `hybrid systems' which combine connectionist components with traditional symbolic processing. I attempt below to outline the general architecture of such a hybrid system. (shrink)

An ontological extension of dispositional essentialism is proposed, whereby what is necessary and sufficient for the dispositional causation of events is interpreted realistically, and postulated to exist. This ‘generative realism’ leads to a general concept of ‘substance’ as constituted by its more fundamental powers or propensities appearing in the form of some structure or field. This neo Aristotelian view is reviewed historically, and in respect to quantum physics.

In a pragmatic approach to ontology, what is necessary and sufficient for the dispositional causation of events is interpreted realistically, and postulated to exist. This leads to a concept of `generic substance' (Aristotle's underlying `matter') as being constituted by dispositions, not just being the `bare subject' for those dispositions. If we describe the forms of objects according their spatiotemporal range, then this form is best viewed as a field, and substances themselves are best conceived as `fields of propensity'.

I formulate a description of the world of relativity and quantum physics that is independent of classical physics, so that we can bypass some of the unwanted legacies which have accumulated from the theories of material corpuscles. The task of this book is to produce a formulation in sufficient detail that an understanding of quantum physics begins to be possible. Even though the present investigations will not produce a complete physical theory, I hope to show that they are still valuable (...) in providing some general ideas which are reasonable, which can be realistically interpreted, and which contribute in some part to our understanding of the world we live in and its quantum peculiarities.

Since the failure of both pure corpuscular and pure wave philosophies of nature, process theories assume that only events need to exist in order to have a physics. Starting from an ontology of actual events, a dispositional analysis is shown here to lead to a new idea of substance, that of a `distribution of potentiality or propensity'. This begins to provide a useful foundation for quantum physics. A model is presented to show how the existence of physical substances could be (...) a reasonable consequence of a theory of processes.

We may suspect that quantum mechanics and consciousness are related, but the details are not at all clear. In this paper, I suggest how the mind and brain might fit together intimately while still maintaining distinct identities. The connection is based on the correspondence of similar functions in both the mind and the quantum-mechanical brain. Accompanying material for a talk at The Second Mind and Brain Symposium held at the Institute of Psychiatry, Denmark Hill, London on 20th October, 1990.

A model is presented to show how the existence of physical law could be a reasonable consequence of Divine Immanence in the world of natural phenomena. Divine Immanence is seen as the continual production of the principal causes or dispositions which enable created things to act and change. It..

The conduct of prior ethics review of human research projects helps to protect vulnerable groups or populations from potential negative impacts of research. Contemporary considerations in human research considers the concept of vulnerability in terms of access to research opportunities, impacts on the consenting process, selection bias, and the generalisability of results. Recent work questions the validity of using enumerated lists as a check box approach to protect research participants from exploitation. Through the use of broad categories to treat cohorts (...) of human research participants as homogenous classes and label some participants as vulnerable merely because they are members of a particular class, some ethics reviewers have used the National Statement on Ethical Conduct in Human Research to strip individuals of their “ethical equality”. Labelling people as vulnerable does not help researchers or human research ethics committee members develop an understanding of the complexities of applying the principles of respect and of justice in ethical decision-making. Conversely, defining specific cohorts of research participants as needing nuanced ethical consideration, due to their vulnerable nature, may imply that other population groups need not be considered vulnerable. We contend that this assumption is erroneous. This paper explores the way that human research ethics guidance documents treat vulnerability within the Australian context and draws on contemporary discussion to focus an alternative perspective based on the principles in the National Statement on Ethical Conduct in Human Research for researchers and human research ethics committee members to consider.

Behrendt & Young (B&Y) propose a useful theoretical framework for the study of processes underlying perception and hallucinations. It focuses on gamma oscillations in thalamocortical networks and the role of the reticular thalamic nucleus in modulating these oscillations. I suggest that their theoretical model might also be applied to the investigation of temporal encoding deficits in disorders such as dyslexia. I further suggest, however, that a role for slower rhythms, such as theta, might also be considered when investigating perceptual experience.

The Timaeus is perhaps the most unusual of Plato’s dialogues. In this paper, I attempt to interpret Timaeus’s strange speech, which makes up most of the dialogue. I argue that Timaeus has grasped the grave challenge posed to philosophic reason by men like Hesiod who claim that mysterious gods are the first causes of the world, and therefore one cannot say that there are any true necessities governing this world. If this is true, then philosophy, as the study of nature, (...) which depends on the existence of necessity, would be impossible. Timaeus articulates two serious attempts to meet this challenge by demonstrating the stability and rational comprehensibility of the world from solid first principles: one according to which mind is the cause of all things; another according to which everything comes to be through mindless necessity. But he ultimately suggests that neither of these attempts have been successful, thereby demonstrating the limits of natural science’s ability to meet the religious challenge. Timaeus’s speech also has a rhetorical purpose related to this failure: insofar as he finds himself unable adequately to meet the religious challenge, and yet is still attracted to and finds worthwhile the pursuit of philosophy, he thinks a rhetorical account of the cosmos is necessary to shore up faith in reason for elite and educated young men who find themselves inclined to natural science. The more rhetorical aspects of Timaeus’s speech, and above all his account of the triangles, serve this purpose. (shrink)

As one might expect of an author of the complexity of John of Salisbury, there is little scholarly agreement regarding the proper interpretation of the major features of his social and political thought. The twelfth-century church-man has always been a controversial figure. Since the late Middle Ages, the ideas contained in his main contribution to political theory, the Policraticus , have been widely analyzed and interpreted. In more recent years, controversy has raged about the nature and significance of many of (...) his main doctrines , his source materials, and his attitudes towards contemporary events and people.
