Fechner's conception of psychophysics included both “outer psychophysics” the relation between stimulus intensity and the response reflecting sensation strength, and “inner psychophysics” the relation between neurelectric responses and sensation strength. In his own time outer psychophysics focussed on the form of the psychophysical law, with Fechner espousing a logarithmic law, Delboeuf a variant of the logarithmic law incorporating a resting level of neural activity, and Plateau a power law. One of the issues on which the dispute was focussed concerned the (...) appearance of contrasts if the overall illumination was increased or decreased; another issue was the question of whether a sensation of a “just noticeable difference” established for one value of a sensory dimension appeared the same for a value elsewhere on the dimension. The development of “inner psychophysics” led through the works of Delboeuf, Solomons, Jastrow, and Thurstone to modern signal detection theory. A third line of research, devoted to the question of what was meant by the “measurement” of sensation strength, stemmed from the criticism of Fechner's work by von Kries (1882) and others. Although a valid body of science could be built up without the intervening variable called “sensation strength,” such a science might be a cumbersome representation of reality. When an optical contrast is set up, and its overall illumination is increased or decreased, subjective contrasts involving medium levels of lightness vary little as illumination varies (as a power law based on sensation ratios or a logarithmic law based on sensation differences predict), but subjective contrasts involving extreme levels of lightness might be subject to the effects of other variables.

. In Aristotle's account, corrective and distributive justice are not particular substantive ideals, but are rather the formal patterns that inhere in interactions and in the legal arrangements that regulate them. Corrective and distributive justice are the structures of ordering internal to transactions and distributions, respectively. The Aristotelian. forms of justice thus constitute the rationality immanent to the relation ships of mutually external beings. This article stresses Aristotle's formalism, contrasting it to modem instrumental conceptions of legal rationality, and defending it (...) against Kelsen's allegations of emptiness. The article concludes with the suggestion that corrective justice, as the conceptual pattern that makes private law what it is, can be considered the formal and final cause of private law. (shrink)

It has at various times been said, both before and since the fall of apartheid, that philosophers in South Africa are neglecting to do certain sorts of work. Behind this accusation lies a general claim that philosophers have responsibilities to their contexts. This essay is dedicated to (i) defending this claim against objections, and (ii) offering a positive argument for there being moral pressure on philosophers to increase understanding. My aim is not to accuse any philosopher or community of philosophers (...) of neglect. It is rather to defend an understanding of both philosophy and ethical responsibilities that makes room for philosophers to have moral responsibilities. Whether or not it has ever in fact been appropriate to accuse philosophers in South Africa, or indeed anywhere else, of neglect, philosophers do indeed have responsibilities to their contexts.

The four theses of this paper are: that an appropriate organizational form is used to design, define, and organize a functional unit of a legal system, that the functional units of a legal system, contrary to the emphasis in Hart and Kelsen, consist of far more than rules, and include institutions, interpretive and other methodologies, sanctions and remedies, and more, that frontal and systematic study of the forms of these units is a major avenue for advancing understanding of them as (...) duly organized wholes, and, that such study reveals that much credit is due these forms, along with complementary material or other components of the units, for values realized through law.

Proponents of philosophy for children generally see themselves as heirs to the ‘Socratic’ tradition. They often claim too that children’s aptitude for play leads them naturally to play with abstract, philosophical ideas. However in Plato’s dialogues we find in the mouth of ‘Socrates’ many warnings against philosophising with the young. Those dialogues also question whether philosophy should be playful in any straightforward way, casting the distinction between play and seriousness as unstable. It seems we cannot think of Plato as representing (...) how to engage in dialectic, nor as prescribing a method for doing so. The irreducible textuality of the dialogues defeats any attempt to read them in this way. This is not to criticise the practice of philosophy for children: only to note the ambivalence and instability of the philosophical heritage that it wants to claim. (shrink)

It is sometimes said that we are strangers to ourselves, bearers of internal alterity, as well as to each other. The profounder this strangeness then the greater the difficulty of giving any systematic account of it without paradox: of supposing that our obscurity to ourselves can readily be illuminated. To attempt such an account, in defiance of the paradox, is to risk knowingness: a condition which, appearing to challenge our alterity but in fact often confirming it, holds an ambiguous place (...) in the ?ethics of belief? and has largely escaped philosophical attention. Like alterity, knowingness can only be approached indirectly. Charles Dickens, in David Copperfield, is exemplary in the way he handles these themes. (shrink)

This is a study of ethical and moral behavior, or perhaps unethical behavior, in two different societies. One society, contemporary Australia and in particular the state of Western Australia, is currently undergoing an exhaustive Royal Commission into the shenanigans of a number of well-known business men and former leading politicians who seem to have been playing fast and loose with large amounts of other peoples' money. While this was initially the major focus of the paper, a secondary focus developed based (...) on the interest shown in acquiring an historical background by a group of business policy students. The opportunity to acquire an appreciation of historical events and in particular, the development of a sense of history seems to be lacking in the curricula of modern day business students. The secondary focus of the paper therefore illustrated that malfeasance, misfeasance and other forms of malpractice in business and administration were just as common in Greco-Roman times as today. In this context, reference has been made to a selection of the writings of some of the more well-known writers of this period. The paper ends on a nonpositive note, raising the (rhetorical) question, that if, after two thousand years people are still continuing to engage in sharp business practices whenever the occasion arises is there any point in developing and offering courses in moral behavior and business ethics?

Abstract This paper seeks to argue that Socrates? thought on the connection between death?contemplation and genuine philosophising as reported in Plato's Phaedo, is comparable in many ways to the insight on the same connection contained in the Katha Upanishad. While refraining from a general comparison of the Platonic and the Upanishadic systems, the paper attempts to show, through an original exposition of Phaedo as well as the Katha Upanishad, that both these classics emphasise the value of death?contemplation for a thoughtful (...) and fundamental assessment of human existence, which is but a genuine task of philosophy.

Reason has regularly been portrayed and understood in terms of images and metaphors that involve the exclusion or denigration of some element-body, passion, nature, instinct-that is cast as "feminine." Drawing upon philosophical insight into metaphor, I examine the impact of this gendering of reason. I argue that our conceptions of mind, reason, unreason, female, and male have been distorted. The politics of "rational" discourse has been set up in ways that still subtly but powerfully inhibit the voice and agency of (...) women. (shrink)

Much of the debate concerning political obligation deals with the question of which, if any, moral principles could make obedience to the directives of the government a matter of obligation. What makes political obligation political has not received attention in the literature on the topic. In this article I argue that the lack of systematic reflection on what makes political obligation political is responsible for the failure of a number of influential theories of political obligation. I demonstrate this failure using (...) the consent theory of political obligation as my major example. I conclude my analysis by formulating some positive conditions that a successful principle of political obligation should satisfy. (shrink)

Although the extent to which motivational factors are involved in the production and sustaining of biased or 'irrational' beliefs continues to be a controversial issue in social psychology, even those who urge that such beliefs are often explained by non-motivational tendencies admit that biased beliefs sometimes have motivational sources. Sometimes toe are influenced by motivational pressures in ways proscribed by principles that we accept for belief-acquisition or belief-revision ('doxastic' principles). Many garden-variety instances of self-deception are cases in point. We are (...) not always helpless victims of those pressures, however. This paper examines the nature of doxastic self-control (roughly, a capacity to counteract motivational pressures that incline us to acquire or retain beliefs that would violate our doxastic principles) and explores our prospects for avoiding motivationally biased believing by exercising self-control.

Peter Winch, in his political philosophy, wanted to rethink the concepts of political authority, legitimacy and political culture, with a starting point in Wittgensteinian ideas. This essay brings together Winch's thoughts on political authority. Developing insights from Wittgenstein's work on certainty, Winch emphasised the unstated background behind any normative stand concerning authority. Ideas of legitimacy and civil society are formed within historically specific political cultures. In the 1990s, Winch was increasingly inclined to emphasise disagreement, which was related to his developing (...) views on understanding, logic and reasoning. This development is traced, in part, on the basis of unpublished lecture notes. (shrink)

This paper deals with two forms of education—Platonic and Socratic. The former educates childhood to transform it into what it ought to be. The latter does not form childhood, but makes education childlike. To unfold the philosophical and pedagogical dimensions of this opposition, the first part of the paper highlights the way in which philosophy is presented indirectly in some of Plato’s dialogues, beginning with a characterisation that Socrates makes of himself in the dialogue Phaedrus. The second part details Plato’s (...) condemnation of writing in the Phaedrus, and draws on the critique by Jacques Derrida and Gilles Deleuze to establish what is at stake in this condemnation. In the third part, the pedagogical and political implications of this condemnation are reviewed, and Plato is placed in a surprising position in relation to his own teacher, Socrates. Finally, through a comparison between childhood and philosophy, the educational value of putting childhood and philosophy together is questioned. Through a number of questions, the paper ends problematising the pedagogical, political and philosophical value of placing the practice of philosophy in the realm of childhood citizenship education. It also recovers the value of philosophy—as a form of questioning and unlearning what we know and affirming the value of not knowing—in a childlike education. (shrink)

This essay examines the question of whether language, knowledge, and truth are possible in a world of relativism and flux, developing along a line of comparison between the Cratylus and Theaetetus of Plato on the one hand, and the Zhuangzi 莊子 of the Daoist philosophical tradition on the other. Against Plato’s image of “leaky pots” that symbolizes the impossibility of language in a state of flux, the Zhuangzi introduces “spillover-goblet words” that resist the language of necessity and essence by continually (...) emptying themselves out, only to be filled again with the always contingent. To put the ideas and metaphors of each of these perspectives into conversation, the essay drafts a comparison between two manners of animal classification, with classical taxonomy aligning with Platonism on the one hand, and the evolutionary science of “cladistics”—taxonomy based on ancestry—allying with Daoism on the other. In the end, it is Plato who is left holding his pejorative “leaky pots,” as under conditions of essential change it is putatively unchanging categories themselves that are shown to create the worst problems for knowledge.

For Gadamer, understanding moves between two different levels. One is the everyday ontological level in which there is a meeting between the familiar and the alien, between the known and the not‐quite‐expected. But understanding can also be a skill to be developed. This is the way in which we achieve good knowledge. In pedagogical terms, encountering the alien is the basis for self‐formation, or bildung, originating in Hegel. But there is an ambiguity at the heart of bildung. The notion of (...) encountering the alien runs together two different notions: (a) being pulled up short, as elaborated by Deborah Kerdeman; and (b) allowing oneself to be interrogated by the other, as described by Charles Taylor. And each of these has affective psychodynamic parallels in Jungian and Freudian psychology, the first in the notion of deflating hubris, and the second, in the reintegration of projection. The experiences of encountering the alien in these two forms can be extremely intense for university students and they constitute significant self‐transformations. (shrink)

The Holographic Principle holds that the information in any region of space and time exists on the surface of that region. Layers of the holographic, universal “now” go from the inception of the universe to the present. Universal Consciousness is the timeless source of actuality and mentality. Information is experience, and the expansion of the “now” leads to higher and higher orders of experience in the Universe, with various levels of consciousness emerging from experience. The brain consists of a nested (...) hierarchy of surfaces that range from the most elementary field through the neuron, neural group, and the whole brain. Evidence from the evolution and structure of the brain shows that optimal surface areas in a variety of structures are conserved with respect to underlying surfaces. Microgenesis, the becoming of the mental state through a process of recapitulation of development and evolution, is in full accord with the Holographic Principle. Evidence from a wide variety of contexts indicates the capacity on the mind for total recall of past life events and for access to universal information, indicating connection with the holographic surfaces of prior “nows” and with the Universal holographic boundary. In summation, the Holographic Principle can help us explain the unity and mechanisms of perception, experience, memory, and consciousness. (shrink)

On one standard reading, Plato's works contain at least two distinct views about the structure of the human soul. According to the first, there is a crucial unity to human psychology: there is a dominant faculty that is capable of controlling attention and behaviour in a way that not only produces right action, but also ‘silences’ inclinations to the contrary—at least in idealized circumstances. According to the second, the human soul contains multiple autonomous parts, and although one of them, reason, (...) normatively dominates the others, it may fail to do so descriptively: even in the face of full, explicit, well‐reasoned, conscious awareness of the truth of a claim, a person may continue to feel residual inclinations towards disavowed, inappropriate and misguided experiences and courses of action. In this paper, I will argue that even the second of these views does not fully capture the ways in which reflective commitment fails to guide human action. Whereas the traditional multi‐part soul view is well suited to explaining phenomena that involve a cognitive conflict between our reflective attitudes and our non‐reflective endorsements, it falls short when we turn to the full array of human patterns of response, because it neglects a further source of challenge to reason's rule, namely, the mediation of associative and heuristic processes. These processes introduce complications for which the simple faculty psychology view cannot adequately account. Because they produce challenges to reason's rule that are phenomenologically invisible, traditional strategies for self‐regulation cannot be straightforwardly applied to their management. (shrink)

With the publication of this inaugural issue of the internationally peer-reviewed journal Biosemiotics, our still-developing young interdiscipline marks yet another milestone in its journey towards adulthood. For this occasion, the editors of Biosemiotics have asked me to provide for those readers who may be newcomers to our field a very brief overview of the history of biosemiotics, contextualizing it within and against the larger currents of philosophical and scientific thinking from which it has emerged. To explain the origins of this (...) most twenty-first century endeavour effectively, however, will require tracing—at least to the level of a thumbnail sketch—how the ‘sign’ concept appeared, was lost, and now must be painstakingly rediscovered and refined in science. To relate this long history, this article will appear in Biosemiotics in three instalments, examining, respectively: (1) The History of the Sign Concept in Pre-Modernist Science, (2) The History of the Sign Concept in Modernist Science, and (3) The Biosemiotic Attempt to Develop a More Useful Sign Concept for Contemporary Science. In this instalment, we begin our introductory ‘stroll through the woods of sciences and signs’ by following the development of the sign concept within the context of scientific inquiry, in necessarily broad outline, from the beginnings of such inquiry in sixth century BCE, through its long development in the Middle Ages, and up unto the onset of modernity. For only within this larger historical context can our contemporary attempt to develop a naturalistic understanding of sign relations be understood. (shrink)
