Representationalism emerges unscathed from Pessoa et al.'s attack. They fail to undermine a key reason for its influence: it has the theoretical resources to explain many illusory visual experiences such as illusory contours and features. Furthermore, in attempting to undermine representationalism, the authors seem to erect an unduly inflated distinction between neural accounts of perception and personal-level accounts of perception.

What is perception doing in mathematical reasoning? To address this question, I discuss the role of perception in geometric reasoning. Perception of the shape properties of concrete diagrams provides, I argue, a surrogate consciousness of the shape properties of the abstract geometric objects depicted in the diagrams. Some of what perception is not doing in mathematical reasoning is also discussed. I take issue with both Parsons and Maddy. Parsons claims that we perceive a certain type of abstract object. Maddy claims (...) (at least at one time claimed) that perception provides the basis for intuition of mathematical sets. 1 Mathematical reasoning with diagrams 2 Do we perceive abstract objects? 3 Do we perceive mathematical sets?

Shepard claims that “evolutionary internalization of universal regularities in the world” takes place. His position is interesting and seems plausible with regard to “default” motion detection and aspects of colour constancy which he addresses. However, his claim is not convincing with regard to object recognition. [Shepard].

This paper critiques a recent article in this journal in terms of its use of persuasive techniques. The central issue of the original article by Miles, Munilla and Covin and this paper is whether there should be a change in intellectual property rights to address the needs of impoverished people who are HIV positive or have full blown AIDS and the countries that do not have the means to buy AIDS medication in the absence of subsidies. This paper argues that (...) patents are state sanctioned monopolies that worked effectively for nearly a century. However, new circumstances and a globally interdependent world represent a new environment calling for an adjustment in the conventional public policy premises underlying patents. Most of the meaning and complexity of this issue is lost to the persuasive techniques of the original article. (shrink)

Many business and government institutions appear to have failed in meeting society’s expectations of them. Continuing scandals and failures, as well as an increasingly obvious lack of responsibility to customers, have caused communities to question the probity and operation of these organisations. Consequently, “social licence to operate” is becoming an increasingly common process and one which demands a change in management philosophy and behaviour in our institutions. Improving the quality of responsible management practice is a critical element in this new (...) management philosophy, and which demands an intense focus on including ethical considerations in the core management competence of decision-making. We draw on a combined 100-plus years of international consulting experience, “C“ and senior executive work experience, and academic research to present a practical framework for responsible management practice which, we believe, can also form the foundation for the required organisational cultural transformation required of many existing organisations.

Mature rats were kept on protein-deficient diets to test the hypothesis that late-onset protein restriction results in deficits and to determine the feasibility of doing nutrition-behavior research with old naive animals. A 3% low-protein (LP) group and a 24% adequate-protein (AP) pair-fed control were used. Body weights and plasma protein concentrations were lower and exploratory behavior and motor coordination were poorer for LP rats. Both groups preferred the 24% protein diet. LP rats habituated slower and failed to overcome an initial (...) black preference on an oddity discrimination learning task. Nutrition-behavioral research with older rats is feasible, and late-onset protein restriction produces psychobiological deficits. (shrink)

Alfred Tarski’s work on truth has played such a central role in the discourse on truth that most coming to it for the first time have probably already heard a great deal about what is said there. Unfortunately, since the work is largely technical and Tarski was only tan- gentially philosophical, a certain incautious assimilation dominates many philosophical discussions of Tarski’s ideas, and so, examining Tarski on the concept of truth is in many ways an act of unlearning. -/- In (...) this paper I focus on those key ideas in Tarski’s work that have made a lasting impact on the philosophical discourse. These are the notions of T-sentence, Convention T, Tarskian truth definition, and Tarski’s general limiting theses on the expressibility and definability of truth. Though these ideas are in name familiar, we will seek in this essay to uncover and remove certain widespread misunderstandings of each. Tarski’s name also features prominently in discussions of the liar paradox, so we will take time out to explain Tarski’s connection to this ancient puzzle. (shrink)

blurb from publisher: "In Apperception and Self-Consciousness in Kant and German Idealism, Dennis Schulting examines the themes of reflexivity, self-consciousness, representation and apperception in the philosophy of Immanuel Kant and German Idealism more widely. Central to Schulting’s argument is the claim that all of human experience is inherently self-referential and that this is part of a self-reflexivity of thought, or what is called transcendental apperception, a Kantian insight that was first apparent in the work of Christian Wolff and came (...) to inform all of German Idealism. In a rigorous text suitable for students of German philosophy and upper-level students of metaphysics, epistemology, moral and political philosophy, and aesthetics courses, the author establishes the historical roots of Kant’s thought and traces it through to his immediate successors Karl Leonhard Reinhold, Johann Gottlieb Fichte and Georg Wilhelm Friedrich Hegel. He specifically examines the cognitive role of self-consciousness and its relation to idealism and places it in a clear and coherent history of rationalist philosophy." . (shrink)

One major theme in Pope Benedict XVI’s encyclical Caritas in Veritate is the “Principle of Gratuitousness.” The point of this essay is to begin a reflection on what it actually means and its possible relevance. By comparing the “Principle of Gratuitousness” and its normative assumptions about “the logic of gift” with anthropological studies focused on the same phenomenon, I hope to show, not only the relevance of the encyclical’s normative vision but also where and how it needs further clarification. The (...) findings of empirical anthropology provide qualified support for the encyclical’s focus on generating and replenishing “social capital” in order to sustain both markets and politics in an effort to “civilize the economy.” In order to put the “Principle of Gratuitousness” into more effective practice, the encyclical highlights the creative role of “civil society” and calls for the creation social enterprises whose goals are broader and deeper than maximizing profits. Assessing the realism of Benedict’s proposal will require further research and reflection on innovative entrepreneurial ventures designed to address social problems on a commercial basis, for example, Muhammad Yunus’ concept of a “social business” and its development in a series of joint business ventures involving the Grameen Bank and related organizations.

Several writers have tried to describe the foundations of an egalitarian moral view. Their aim is to explain the way of thinking on which distinctively egalitarian conclusions depend. Egalitarianism is frequently located by reference to utilitarianism. The basic features of the utilitarian view are reasonably well understood and most of us find it at least plausible. Egalitarians want to show that their own view differs from the utilitarian view in some fundamental respect. They hope to convince us that the egalitarian (...) stand on that fundamental matter is at least as plausible as that of utilitarianism. (shrink)

It has been argued that, on Kantian grounds, pedophiles, rapists and murderers are morally obligated to take their own lives prior to committing a violent action that will end their moral agency. That is, to avoid destroying the agent's moral life by performing a morally suicidal action, the agent, while he still is a moral agent, should end his body's life. Although the cases of dementia and the morally reprehensible are vastly different, this Kantian interpretation might be useful in the (...) debate on the permissibility of suicide for those facing dementia's effects. If moral agents have a duty to act as moral agents, then those who will lose their moral identity as moral agents have an obligation to themselves to end their physical lives prior to losing their dignity as persons.

We review the current situation in the philosophy of time, partly to investigate Michael Dummett’s complaint that the philosophy of physics has become too specialized and technical to be able to communicate with mainstream philosophy. We conclude that the situation in this case is different: there is no special difficulty of intelligibility---the obstacle for communication between science and philosophy here is rather that what physics, or science in general, tells us is prima facie in conflict with common sense and intuition. (...) We argue that this difficulty is indeed prima facie: on closer inspection it appears that the scientific B-theory may explain our intuition better than the A-theory, even though the latter at first sight seems to completely mirror our direct experience.

In a most interesting recent essay on Derrida and French philosophy, written by Peter Salmon, a well-known contemporary critique of Enlightenment conceptions of subjectivity was rehearsed, namely as being biased towards a Eurocentric male perspective, which presumes to present a ‘neutral’ view of subjective identity, valid for everyone, always, and universally, without regard for particular personalities, histories, cultural backgrounds, sex or privilege. I criticize this view, in particular with respect to Kant.

There is certainly a lot of academic buzz these days around the relationship between Buddhism and physics. Of course, as we learned from Donald Lopez's famed book Buddhism and Science, there is a long history, beginning in the nineteenth century, to this proclamation that Buddhism is compatible with modern day science. Indeed, Dean Anthony Brink's book Philosophy of Science and the Kyoto School: An Introduction to Nishida Kitaro, Tanabe Hajime and Tosaka Jun is one of many contemporary examples of this (...) effort to forge this intimate connection--except that this effort is launched from the perspective of the Kyoto School's approach to physical phenomena. Unlike Lopez's work, which is less interested in... (shrink)

In this paper, I argue that a constitutionalized Harm Principle could ensure that people are not jailed unless they deserve it. I do not aim to outline every possible type of bad consequence beyond harm that might be sufficiently serious to justify criminalization. Instead, I focus on criminalization that is backed up with jail terms and I argue that wrongful harm to others provides the only moral and constitutional justification for sending people to jail. Imprisonment harms the prisoner, so she (...) should not be imprisoned unless she has caused proportionate harm to others. I argue that the sufficient conditions for sending an offender to jail are: (1) that the offender's actions have (or risk) bad consequences that are sufficiently harmful to make her commensurately deserving of penal detention; and (2) that the offender culpably (that is, with a state of mind somewhere along the intentional/reckless/gross negligence continuum) chose (aimed or attempted) to bring about those bad consequences or did so with reckless indifference. The lawmaker would need to demonstrate from the ex ante perspective that proposed offenses carrying jail sentences are a proportionate and fair way of dealing with the wrongs involved. Because jail (including short sentences of a few days) involves hard treatment (seriously harmful consequences for the prisoner) harm to others would be the only bad consequence of sufficient weight to justify a jail sentence. Jailing people for wrongful behavior that has harmless consequences would be an unjust and disproportionate response. In terms of understanding imprisonment (a physical deprivation of liberty) in the United States, it is better to refer to the Eighth Amendment of the Constitution than to the Due Process Clause. The Eighth Amendment, if read morally, could be invoked to strike down laws that carry prison sentences for wrongs that do not result in harm to others. This is because harming a person by subjecting her to the hard treatment that is involved in serving a jail term would be a disproportionate response unless the wrongdoer inflicted equivalent harm on others. I argue, that the Eighth Amendment should be interpreted in a way that accords with its overall moral aim or purpose. The Amendment's overall moral aim is to ensure that the state does not inflict unjust, oppressive, or disproportional punishments on its citizens. (shrink)

Bonaventure’s Sentence Commentary provides the most comprehensive set of trinitarian arguments to date. This article focuses on just one of them, the one from beatitude. Roughly, beatitude can be thought of as God’s enjoyment of his own, supreme goodness. After a brief rationale of Bonaventure’s speculative project, I assay the concept of beatitude and exposit his four-stage argument. Bonaventure reasons: (i) for a single supreme substance; (ii) for at least two divine persons; (iii) against the possibility for an infinite number (...) of divine persons; (iv) for at least three, and against the possibility of four (or more) divine persons. I show how this line of reasoning is significantly more complex than Bonaventure’s terse summaries initially indicate. My main goal is to explicate the four steps and unpack their main support. Along the way I attend to the argument’s sources, logical progression, and I respond to several concerns. (shrink)
