The phenomenon of ambivalence is an important one for any philosophy of action. Despite this importance, there is a lack of a fully satisfactory analysis of the phenomenon. Although many contemporary philosophers recognize the phenomenon, and address topics related to it, only Harry Frankfurt has given the phenomenon full treatment in the context of action theory - providing an analysis of how it relates to the structure and freedom of the will. In this paper, I develop objections to Frankfurt's account, (...) all revolving around the charge that his account contains a serious ambiguity between willing and identifying. With such objections in place, I then develop an analysis that avoids the difficulties and ambiguities that Frankfurt's analysis is prey to. I briefly distinguish ambivalence from other types of internal conflict. This paper aims to offer conceptual clarification on the phenomenon of ambivalence, which will then allow for discussions about the normative merits and demerits of ambivalence, the effects of ambivalence on autonomous action, and methods of resolution of ambivalence.

The handicap principle has come under significant challenge both from empirical studies and from theoretical work. As a result, a number of alternative explanations for honest signaling have been proposed. This paper compares the evolutionary plausibility of one such alternative, the "hybrid equilibrium," to the handicap principle. We utilize computer simulations to compare these two theories as they are instantiated in Maynard Smith's Sir Philip Sidney game. We conclude that, when both types of communication are possible, evolution is unlikely to (...) lead to handicap signaling and is far more likely to result in the partially honest signaling predicted by hybrid equilibrium theory.

The dominance in normal awareness of visual percepts, which are linked to space, obscures the fact that most thoughts are non-spatial. It is argued that the mind is intrinsically non-spatial, though in perception can become compresent with spatial things derived from outside the mind. The assumption that the brain is entirely spatial is also challenged, on the grounds that there is a perfectly good place for the non-spatial in physics. A quantum logic approach to physics, which takes non-locality as its (...) starting point, offers a non-reductive way of reconciling the experience of mind with the world description of physics. For further progress it is necessary to place mind first as the key aspect of the universe. (shrink)

“Situationists” such as Gilbert Harman and John Doris have accused virtue ethicists as having an “empirically inadequate” theory, arguing that much of social science research suggests that people do not have robust character traits as traditionally thought. By far, the most common response to this challenge has been what I refer to as “the rarity response” or the “rarity thesis”. Rarity responders deny that situationism poses any sort of threat to virtue ethics since there is no reason to suppose that (...) the moral virtues are typical or widespread. But, far from being its saving grace, I will argue, the rarity thesis forces virtue ethicists into positions that are incompatible with their theoretical foundations or render their theory normatively irrelevant. The more the virtue ethicists modify their thesis to fit the empirical evidence and to be normatively relevant, the less they retain a virtue ethical theory. This is also the case for virtue epistemologists. (shrink)

This is a collection of essays based on papers read at a conference on freedom of expression held at McMaster University in May, 1990. Its contributors are philosophers and lawyers, each of whom brings his unique perspective to bear on issues surrounding the justification of free expression and the bases, both legal and moral, for restricting or broadening its scope. Joseph Magnet, Wayne Sumner, and James Weinstein discuss legal attempts in America and Canada to restrict hate literature, while David Richards (...) brings a specifically American perspective to wider issues of free speech. Joseph Raz and Jan Narveson attempt to ground their theories of free speech in a wider political theory, while Leslie Green and Roger Shiner discuss more specific aspects of free expression, namely, the freedom to express oneself in the language of one's choice and freedom of commercial expression.

In their article “The Concept of Voluntary Consent,” Robert Nelson and colleagues (2011) argue for two necessary and jointly sufficient conditions for voluntary action: intentionality, and substantial freedom from controlling influences. They propose an instrument to empirically measure voluntariness, the Decision Making Control Instrument. I argue that (1) their conceptual analysis of intentionality and controlling influences needs expansion in light of the growing use of behavioral economics principles to change individual and public health behaviors (growing in part by the designation (...) of “The Science of Behavior Change” as a new National Institutes of Health [NIH] Roadmap Activity); and (2) that their measure of voluntariness that relies on self-perceived intentionality and extent of control is unreliable, given findings from behavioral economics and cognitive science that show that our perceptions about the intentionality and control of our own and others’ decisions and actions are remarkably skewed and un-insightful.

'Uncertainty and chance' is a subject with a broad span, in that there is no academic discipline or walk of life that is not beset by uncertainty and chance. In this book a range of approaches is represented by authors from varied disciplines: natural sciences, mathematics, social sciences and medical sciences. At one extreme, this volume is concerned with the foundations of probability. At the other extreme, we have scholars who acknowledge the concept of chance and uncertainty but do not (...) cope with it by means of systematic measurement or quantative analysis. (shrink)

This comprehensive and important volume includes contributions by activists, journalists, lawyers and scholars from twenty-one countries. The essays map the directions the movement for women's rights is taking--and will take in the coming decades--and the concomittant transformation of prevailing notions of rights and issues. They address topics such as the rapes in former Yugoslavia and efforts to see that a War Crimes Tribunal responds; domestic violence; trafficking of women into the sex trade; the persecution of lesbians; female genital mutilation; and (...) reproductive rights.

The strange story of the von Neumann impossibility proof is recalled, and the even stranger story of later impossibility proofs, and how the impossible was done by de Broglie and Bohm. Morals are drawn.

I Have argued elsewhere, and still believe, that the Phaedo was written before Plato's first journey to Italy, when the strong Pythagorean influences displayed in that dialogue were reaching him through the Pythagorean centres on the Greek mainland, in particular Phleius and Thebes; and that in the Republic and Phaedrus it is possible to trace equally strong Pythagorean influence but different in detail, because Plato had now come into contact with the Pythagoreans who still remained in Italy, particularly Archytas. The (...) most remarkable of these influences from whatever source was the doctrine of the immortality and transmigration of the soul, which we know to have been held by the earliest Pythagorean society, and the account of the soul's experience in the world below.

This paper approaches the problem of testimony from a new direction. Rather than focusing on the epistemic grounds for testimony, it considers the problem from the perspective of an individual who must choose whom to trust from a population of many would-be testifiers. A computer simulation is presented which illustrates that in many plausible situations, those who trust without attempting to judge the reliability of testifiers outperform those who attempt to seek out the more reliable members of the community. In (...) so doing, it presents a novel defense for the credulist position that argues one should trust testimony without considering the underlying reliability of the testifier. (shrink)

In this response to Jeff Pflug’s review of my dissertation Michael Polanyi’s Integrative Philosophy, I note that Pflug focused on my discussion of possible extension of Polanyi’s epistemology; he has also taken my statements on scientific truth out of context. In addition, he ignored the four major elements of the dissertation, thereby not giving the reader a “map” to the meaning and the rationale of the work – an intellectual biography of Polanyi.

Hereditary structural completeness is established for a range of substructural logics, mainly without the weakening rule, including fragments of various relevant or many-valued logics. Also, structural completeness is disproved for a range of systems, settling some previously open questions.
