As one of the most important ethicists to emerge since the Second World War, Alan Gewirth continues to influence philosophical debates concerning morality. In this ground-breaking book, Gewirth's neo-Kantianism, and the communitarian problems discussed, form a dialogue on the foundation of moral theory. Themes of agent-centered constraints, the formal structure of theories, and the relationship between freedom and duty are examined along with such new perspectives as feminism, the Stoics, and Sartre. Gewirth offers a picture of the philosopher's theory and (...) its applications, providing a richer, more complete critical assessement than any which has occurred to date. (shrink)

Professor Mitt Regan takes up Brad Wendel's suggestion that we have to distinguish the ethics of advocates from those which guide other forms of legal work, and proposes that the distinction be taken further. Legal advising can itself implicate different ethical positions. Regan concentrates on tax advisers, and argues that their work can, at times, legitimately require a partisan advocate's stance in the giving of tax advice or an impartial trustee's stance in ensuring that the spirit, as well (...) as the letter, of tax law is honoured. Especially in the US, there are strong systemic justifications for treating the tax adviser as an advocate: the wide latitude that tax law gives the citizen when calculating tax liability, the hazards of accurate interpretation of the tax code, and the need for predictability in client arrangements suggesting that it is preferable to concentrate strictly on the letter of the law. So too, the tax adviser as trustee is informed by the importance of tax collection for ordinary government services, and by 'tax morale' and the community's confidence in the tax system generally. The bifurcation of ethical stances in tax advising is, as a consequence, a function of the 'conflicted regulation' of citizen taxpayers. (shrink)

Dietary restriction (DR) is the most consistent environmental manipulation to extend lifespan. Originally thought to be caused by a reduction in caloric intake, recent evidence suggests that macronutrient intake underpins the effect of DR. The prevailing evolutionary explanations for the DR response are conceptualized under the caloric restriction paradigm, necessitating reconsideration of how or whether these evolutionary explanations fit this macronutrient perspective. In the authors’ opinion, none of the current evolutionary explanations of DR adequately explain the intricacies of observed results; (...) instead a context‐dependent combination of these theories is suggested which is likely to reflect reality. In reviewing the field, it is proposed that the ability to track the destination of different macronutrients within the body will be key to establishing the relative roles of the competing theories. Understanding the evolution of the DR response and its ecological relevance is critical to understanding variation in DR responses and their relevance outside laboratory environments. (shrink)

In this essay, I explore the moral foundations of the treatment of animals. Alternative views are critically examined, including (a) the Kantian account, which holds that our duties regarding animals are actually indirect duties to humanity; (b) the cruelty account, which holds that the idea of cruelty explains why it is wrong to treat animals in certain ways; and (c) the utilitarian account, which holds that the value of consequences for all sentient creatures explains our duties to animals. These views (...) are shown to be inadequate, the Kantian account because some of our duties regarding animals are direct duties to animals; the cruelty account because it confuses matters of motive or intent with the question of the rightness or wrongness of the agent’s actions; and the utilitarian account because it could be used to justifyidentifiable speciesistic practices. I defend a fourth view. Only if we postulate basic moral rights in the case of humans, can we satisfactorily account for why it is wrong to treat humans in certain ways, and it is only by postulating that these humans have inherent value that we can attribute to them basic moral rights. Consistency requires that we attribute this same kind of value to many animals. Their havinginherent value provides a similar basis for attributing certain basic moral rights to them, including the right not to be harmed. Possession of this right places the onus of justification on anyone who would harm these animals. I set forth conditions for such a justification which those who would abuse animals have failed to meet. (shrink)

In The Case for Animal Rights, Tom Regan argues that although all subjects-of-a-life have equal inherent value, there are often differences in the value of lives. According to Regan, lives that have the highest value are lives which have more possible sources of satisfaction. Regan claims that the highest source of satisfaction, which is available to only rational beings, is the satisfaction associated with thinking impartially about moral choices. Since rational beings can bring impartial reasons to bear (...) on decision making, Regan maintains that they have an additional possible source of satisfaction that nonrational beings do not have and, consequently, the lives of rational beings turn out to have greater value..

It is common for conservationists to refer to non-native species that have undesirable impacts on humans as “invasive”. We argue that the classification of any species as “invasive” constitutes wrongful discrimination. Moreover, we argue that its being wrong to categorize a species as invasive is perfectly compatible with it being morally permissible to kill animals—assuming that conservationists “kill equally”. It simply is not compatible with the double standard that conservationists tend to employ in their decisions about who lives and who (...) dies. (shrink)

The philosophy of animal rights is often characterized as an exclusively justice oriented approach to animal liberation that is unconcerned with, and moreover suspicious of, moral emotions, like sympathy, empathy, and compassion. I argue that the philosophy of animal rights can, and should, acknowledge that compassion plays an integral role in animal liberation discourse and theory. Because compassion motivates moral actors to relieve the serious injustices that other animals face, or, at the very least, compassion moves actors not to participate (...) in or cause these injustices, the philosophy of animal rights can and should recognize both a duty to cultivate compassion and a duty to promote compassion. Contra to feminist critiques of Regan’s justice-approach to ethics, the philosophy of animal rights is not committed to eschewing the moral emotions. (shrink)

For the past thirty years, the late Tom Regan bucked the trend among secular animal rights philosophers and spoke patiently and persistently to the best angels of religious ethics in a stream of publications that enjoins religious scholars, clergy, and lay people alike to rediscover the resources within their traditions for articulating and living out an animal ethics that is more consistent with their professed values of love, mercy, and justice. My aim in this article is to showcase some (...) of the wealth of insight offered in this important but under-utilized archive of Regan’s work to those of us, religious or otherwise, who wish to challenge audiences of faith to think and do better by animals.

The theory and philosophy of artificial intelligence has come to a crucial point where the agenda for the forthcoming years is in the air. This special volume of Minds and Machines presents leading invited papers from a conference on the “Philosophy and Theory of Artificial Intelligence” that was held in October 2011 in Thessaloniki. Artificial Intelligence is perhaps unique among engineering subjects in that it has raised very basic questions about the nature of computing, perception, reasoning, learning, language, action, interaction, (...) consciousness, humankind, life etc. etc. – and at the same time it has contributed substantially to answering these questions. There is thus a substantial tradition of work, both on AI by philosophers and of theory within AI itself. - The volume contains papers by Bostrom, Dreyfus, Gomila, O'Regan and Shagrir. (shrink)

Until now, arguments for the distribution of resources by those who care about the plight of human-used animals have been either utilitarian or libertarian in nature. The utilitarian case has been made in writing by both activists and philosophers. The libertarian case is more a position that I have found comes naturally to many in the animal movement. In this article I make use of elements of Rawls’ A Theory of Justice to make a case for two principles of justice (...) for the distribution of human resources by those in the animal rights community. My argument arises within the tradition of Tom Regan and Marc Rowlands where animals are held to possess negative rights. This is an argument largely by analogy to Rawls’ manner of making a case for his two principles. (shrink)

Change blindness illustrates a remarkable limitation in visual processing by demonstrating that substantial changes in a visual scene can go undetected. Because these changes can ultimately be detected using top–down driven search processes, many theories assign a central role to spatial attention in overcoming change blindness. Surprisingly, it has been reported that change blindness can occur during blink-contingent changes even when observers fixate the changing location [O’Regan, J. K., Deubel, H., Clark, J. J., & Rensink, R. A. . Picture (...) changes during blinks: Looking without seeing and seeing without looking. Visual Cognition, 7, 191–212]. However, eye blinks produce a transient disruption of vision that is independent of any associated changes in the retinal image. We determined whether these ‘attentive blank stares’ could occur in the absence of blink-mediated visual suppression. Using a flicker change-blindness paradigm we confirm that despite direct attentive fixations, obvious scene changes often remain undetected. We conclude that change detection involves object or feature based attentional mechanisms, which can be ‘misdirected’ despite the allocation of spatial attention to the position of the change.

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.

De Interpretatione is among Aristotle's most influential and widely read writings; C. W. A. Whitaker presents the first systematic study of this work, and offers a radical new view of its aims, its structure, and its place in Aristotle's system. He shows that De Interpretatione is not a disjointed essay on ill-connected subjects, as traditionally thought, but a highly organized and systematic treatise on logic, argument, and dialectic.

This study examined self-reported academic dishonesty at a midsize public university. Students (N = 492) rated the likelihood they would cheat after accepting to abide by each of eight honor code pledges before Internet-based assignments and examinations. The statements were derived from honor pledges used by different universities across the United States and varied in length, formality, and the extent to which the statements included consequences for academic dishonesty. Longer, formal honor codes with consequences were associated with a lower likelihood (...) to cheat. Results showed a significant three-way interaction and suggest how to best design honor codes.

Striedter's accessible concept-based book is strong on the macroevolution of brains and the developmental principles that underlie how brains evolve on that scale. In the absence of greater attention to microevolution, natural selection, and sexual selection, however, it is incomplete and not fully modern on the evolution side. Greater biological integration is needed.

This paper presents a longue durée account of the discursive emergence of ‘the market'. It seeks to develop understanding of the ‘crisis system' by showing that the crises of the present have their origins earlier than some critical realist scholars have suggested and can be better understood by the theorization of the generative mechanisms that emerged from the economic and political chaos of the early 1600s. Critical discourse analysis (CDA) is employed to show that in the context of the emergence (...) of capitalism in England, these generative mechanisms resulted in the meaning of the word ‘market’ slipping loose of the geo-spatial semiotic bounds by which it had commonly been delineated – i.e. as a physical space in a town or city where goods were bartered or sold – and being re-semioticised to refer to abstract space where all acts of capitalist economic exchange, including those impacting upon the natural world, take place.

The paper proposes a way of bridging the gapbetween physical processes in the brain and the ''''felt''''aspect of sensory experience. The approach is based onthe idea that experience is not generated by brainprocesses themselves, but rather is constituted by theway these brain processes enable a particular form of''''give-and-take'''' between the perceiver and theenvironment. From this starting-point we are able tocharacterize the phenomenological differences betweenthe different sensory modalities in a more principledway than has been done in the past. We are also (...) ableto approach the issues of visual awareness andconsciousness in a satisfactory way. Finally weconsider a number of testable empirical consequences,one of which is the striking prediction of thephenomenon of ''''change blindness''''. (shrink)

Following arguments put forward in my book (Why red doesn’t sound like a bell: understanding the feel of consciousness. Oxford University Press, New York, USA, 2011), this article takes a pragmatic, scientist’s point of view about the concepts of consciousness and “feel”, pinning down what people generally mean when they talk about these concepts, and then investigating to what extent these capacities could be implemented in non-biological machines. Although the question of “feel”, or “phenomenal consciousness” as it is called by (...) some philosophers, is generally considered to be the “hard” problem of consciousness, the article shows that by taking a “sensorimotor” approach, the difficulties can be overcome. What remains to account for are the notions of so-called “access consciousness” and the self. I claim that though they are undoubtedly very difficult, these are not logically impossible to implement in robots. (shrink)
