This book introduces the reader to ethics by examining a current and important debate. During the last fifty years the orthodox position in ethics has been a broadly non-cognitivist one: since there are no moral facts, moral remarks are best understood, not as attempting to describe the world, but as having some other function - such as expressing the attitudes or preferences of the speaker. In recent years this position has been increasingly challenged by moral realists who maintain that there (...) are moral facts; there is a truth of the matter in ethics, which is independent of our views, and which we seek to discover. Unfortunately much of this interesting debate found in the work of McDowell, Wiggins, Putnam, Blackburn and others is not easily accessible to undergraduates. McNaughton presents many of the major issues in ethics by way of a clear exposition of both sides of this argument and assumes no prior knowledge of philosophy. Topics discussed include: moral observation, moral motivation, amoralism and wickedness, moral weakness, cultural relativism and utilitarianism. The book concludes that a convincing case can be made out for a radical form of moral realism in which moral virtue is found, not in the following of correct moral principles, but rather in the development of moral sensitivity. Moral Vision is a clear and engaged introduction to an important, and often troubling, debate. (shrink)

This is an analytical study of organizational transformation, values that must be present and operationalized for organizations to successfully change, and the role that leadership has in facilitat ing that change. Specifically, using De Geus' model of living and economic companies and taking input from key theorists such as Senge, Quinn, Bolman and Deal, and others, this study examines and analyzes the values and guiding principles that facilitate an organization's ability to transform, quali ties the leadership must possess and how (...) leadership must function as catalysts to facilitate and ener gize successful, positive change.

We give a constructive proof of McNaughton's theorem stating that every piecewise linear function with integral coefficients is representable by some sentence in the infinite-valued calculus of Lukasiewicz. For the proof we only use Minkowski's convex body theorem and the rudiments of piecewise linear topology.

Simon Blackburn can be seen as challenging those committed to sui generis moral facts to explain the supervenience of the moral on the descriptive. We (like perhaps Derek Parfit) hold that normative facts in general are sui generis. We also hold that the normative supervenes on the descriptive, and we here endeavour to answer the generalization of Blackburn's challenge. In the course of pursuing this answer, we suggest that Frank Jackson's descriptivism rests on a conception of properties inappropriate to discussions (...) of normativity, and we see reason to reject descriptivism generally. We also discuss the views of David Brink, Jonathan Dancy and Bernard Williams in this area. (shrink)

In recent years the distinction between agent-relative and agent-neutral reasons has been taken by many to play a key role in distinguishing deontology from consequentialism. It is central to all universalist consequentialist theories that value is determined impersonally; the real value of any state of affairs does not depend on the point of view of the agent. No reference, therefore, to the agent or to his or her position in the world need enter into a consequentialist understanding of what makes (...) an action right or wrong or morally permissible. Consequentialism thus provides an agent-neutral account of both the right and the good. (shrink)

This paper is a brief reponse to some of Douglas Portmore's criticisms of our version of the agent-relative/agent-neutral distinction.

In the context of propositional logics, we apply semantics modulo satisfiability—a restricted semantics which comprehends only valuations that satisfy some specific set of formulas—with the aim to efficiently solve some computational tasks. Three possible such applications are developed.We begin by studying the possibility of implicitly representing rational McNaughton functions in Łukasiewicz Infinitely-valued Logic through semantics modulo satisfiability. We theoretically investigate some approaches to such representation concept, called representation modulo satisfiability, and describe a polynomial algorithm that builds representations in (...) the newly introduced system. An implementation of the algorithm, test results and ways to randomly generate rational McNaughton functions for testing are presented. Moreover, we propose an application of such representations to the formal verification of properties of neural networks by means of the reasoning framework of Łukasiewicz Infinitely-valued Logic.Then, we move to the investigation of the satisfiability of joint probabilistic assignments to formulas of Łukasiewicz Infinitely-valued Logic, which is known to be an NP-complete problem. We provide an exact decision algorithm derived from the combination of linear algebraic methods with semantics modulo satisfiability. Also, we provide an implementation for such algorithm for which the phenomenon of phase transition is empirically detected.Lastly, we study the game theory situation of observable games, which are games that are known to reach a Nash equilibrium, however, an external observer does not know what is the exact profile of actions that occur in a specific instance; thus, such observer assigns subjective probabilities to players actions. We study the decision problem of determining if a set of these probabilistic constraints is coherent by reducing it to the problems of satisfiability of probabilistic assignments to logical formulas both in Classical Propositional Logic and Łukasiewicz Infinitely-valued Logic depending on whether only pure equilibria or also mixed equilibria are allowed. Such reductions rely upon the properties of semantics modulo satisfiability. We provide complexity and algorithmic discussion for the coherence problem and, also, for the problem of computing maximal and minimal probabilistic constraints on actions that preserves coherence.prepared by Sandro Márcio da Silva Preto.E-mail: [email protected]:https://doi.org/10.11606/T.45.2021.tde-17062021-163257.

In this article we argue that the complex connections between gender and fatness have not been fully examined, particularly in so far as they relate to men. We consider the role of early feminist literature in establishing the idea that the fear of fatness is fundamentally tied up with patriarchy and the ways this also underwrites more recent examinations of fatness and gender. Moreover, we assert that popular feminist scholarship has actively produced the assumption that weight is not only a (...) women's issue, but that it is tied up with the very construction of femininity. Through an examination of the cultural history of fatness we show that men have also been caught up in the drive to reshape the body over the last century. However, their concerns have remained largely hidden, framed as they often are in the lexicon of ‘fitness’ and ‘muscularity’. An examination of the limited published material on male concerns with fat reveals that for many men fatness is feminizing – and undermines normative forms of masculinity in threatening ways. We call for further research that considers both female and male experiences of fatness, given the limitations of approaches that focus merely on one or the other. (shrink)

In this paper, the principal objections to unconditional forgiveness are canvassed, primarily that it fails to take wrongdoing seriously enough, and that it displays a lack of self-respect. It is argued that these objections stem from a mistaken understanding of what forgiveness actually involves, including the erroneous view that forgiveness involves some degree of condoning of the offence, and is incompatible with blaming the offender or punishing him. Two positive reasons for endorsing unconditional forgiveness are considered: respect for persons and (...) human solidarity; and it is argued that the latter provides more plausible grounds for it than the former.

Forgiveness usually gets a very good press in our culture: we are deluged with self-help books and television shows all delivering the same message, that forgiveness is good for everyone, and is always the right thing to do. But those who have suffered seriously at the hands of others often and rightly feel that this boosterism about forgiveness is glib and facile. Perhaps forgiveness is not always desirable, especially where the wrongdoing is terrible or the wrongdoer unrepentant. In this book, (...) Garrard and McNaughton suggest that the whole debate suffers from a crippling lack of clarity about what forgiveness really amounts to. They argue that it is more difficult, complex and troubling than many of its advocates suppose. Nevertheless, they conclude, a proper understanding of forgiveness allows us to avoid cheap and shallow forms of it, and enables us to see why it is right and admirable to forgive even unrepentant wrongdoers.

In this paper we defend a version of moral internalism and a cognitivist account of motivation against recent criticisms. The internalist thesis we espouse claims that, if an agent believes she has reason to A, then she is motivated to A. Discussion of counter-examples has been clouded by the absence of a clear account of the nature of motivation. While we can only begin to provide such an account in this paper, we do enough to show that our version of (...) internalism can be defended against putative counter-examples. All theories of motivation which take what motivates to be a psychological state run foul of the following plausible constraint: the reason why you ought to do an action and the reason why you do it can be the same. In our view, however, while what motivates is a reason (which is a fact) the state of being motivated is a cognitive stage, viz. the belief that one has reason to act. In cases where the agent's relevant beliefs are false, then she has no reason to act, but nontheless her action can be explained in other ways. (shrink)

Stephen Kearns and Daniel Star have made the following interesting proposal concerning the relation between practical reasons and evidence : Necessarily: A fact F is a reason for you to φ iff F is evidence that you ought to φ We're not sure about this. Although moving from left to right might be OK, the converse is problematic. For example, the fact that your reliable friend told you that you have overriding moral reason to φ is ….
