The sentential calculus SC of Kalish and Montague is extended to modal sentences. Rules of inference and a derivation procedure are added. The resultant natural deduction system SMC is like a system for S4 due to Fitch, but SMC is for S5 and the restriction on necessity derivation concerns.terminations of such derivations whereas the restriction on strict subordinate proof in Fitch's system concerns the line-by-line development of such proofs. An axiomatic system AxMC for S5 founded on SC is presented and (...) it is shown that SMC and AxMC are equivalent : what ever is derivable in one system is derivable in the other. (shrink)

If we overlook no consequences when we assess the act, and no relevant features when we generalize, can it matter whether we ask 'What would happen if everyone did the same?' instead of 'What would happen if this act were performed?'? David Lyons has argued that it cannot. Two examples are here articulated to show that it can. The first turns on the way consequences are identified and assessed and in particular on the treatment accorded 'threshold consequences'. The second example (...) turns on the way in which the 'social context' of the act (what others would be doing) is taken into account in the generalization. Also included is a formal theory of conditionals from which implications are drawn for utilitarianism and with which I attempt to dispel certain doubts concerning cases employed in my arguments.

This paper addresses issues raised by recent discussion in normative ethics which concern relations between properties of individual actions and of certain groups of actions. First, an ambiguity common to ?everyone can? and ?everyone ought? is examined. Next, a similar ambiguity in talk about consequences is studied; here several procedures for identifying and evaluating consequences are compared. Then a notation that untangles the ambiguities is presented. Next, this notation is employed in an analysis of Marcus Singer's deduction of his generalization (...) argument. Finally, there is a study of the question as to whether or not conflicts are possible between Singer's generalization argument and the dictates of consequences of individual actions. The findings are that such conflicts are or are not possible depending upon how a certain restriction on generalization arguments is interpreted, and that in either case the proponent of generalization arguments is faced with problems.

This essay is arranged in three sections. In the first I consider interaction problems that can frustrate maximizers. My object here is to add to the kind of case discussed by Gauthier, another in which maximizers would not do well. In the next section I set out conditions under which ‘straight’ or ordinary maximizers could avoid their problems as surely and as easily as could Gauthier's ‘constrained’ maximizers. And in the last section I comment on the relative merits of straight (...) and ‘constrained’ maximization. Attention here is paid first to the suggestion that straight maximizers in view of their problems would choose not to be straight maximizers, would indeed choose to be ‘constrained’ maximizers, and that this shows that there is something wrong with straight maximization. Rejecting this inference, I turn in conclusion to the idea that it follows from the ‘incompleteness’ of straight maximization, from the fact that it is not always possible, that there is something wrong with it. This inference too is rejected. (shrink)

The material in this note was developed for a first course in logie to illustrate a standard use of logie in analysis. The object was to present a not entirely trivial or artificial confusion that was amenable to resolution using only the tools of quite elementary logic-no modalities, no restrietions to extensional contexts. Copies o f The Problem were distributed. Then, on another day, A Solution.

J. Howard Sobel has long been recognized as an important figure in philosophical discussions of rational decision. He has done much to help formulate the concept of causal decision theory. In this volume of essays Sobel explores the Bayesian idea that rational actions maximize expected values, where an action's expected value is a weighted average of its agent's values for its possible total outcomes. Newcomb's Problem and The Prisoner's Dilemma are discussed, and Allais-type puzzles are viewed from (...) the perspective of causal world Bayesianism. The author establishes principles for distinguishing options in decision problems, and studies ways in which perfectly rational causal maximizers can be capable of resolute choices. Sobel also views critically Gauthier's revisionist ideas about maximizing rationality. This collection will be a desideratum for anyone working in the field of rational choice theory, whether in philosophy, economics, political science, psychology or statistics. Howard Sobel's work in decision theory is certainly among the most important, interesting and challenging that is being done by philosophers. (shrink)

IntroductionJ. Howard Sobel devotes seventy pages of his wide-ranging analysis of theistic arguments to a critique of the cosmological argument. The focus of that critique falls on the argument a contingentia mundi; but he also offers in passing some criticisms of the argument ab initio mundi, or the kalam cosmological argument.Sobel provides the following Statement of the argument:Everything that begins to exist has a cause of its existence.The universe began to exist.Therefore, the universe has a cause of (...) its existence [that did not begin to exist].Sobel will accept the causal premiss only if ‘begins to exist’ means ‘has a first instant of its existence,’ and he disputes the arguments and evidence for.Traditional proponents of the kalam argument sought to justify by means of philosophical arguments against the infinity of the past, while contemporary interest in the argument arises from the empirical evidence of physical cosmology for the truth of.

Howard J. Curzer presents a fresh new reading of Aristotle's Nicomachean Ethics, which brings each of the virtues alive. He argues that justice and friendship are symbiotic in Aristotle's view; reveals how virtue ethics is not only about being good, but about becoming good; and describes Aristotle's ultimate quest to determine happiness.

This cutting-edge book offers a theoretical account of the evolution of multiple memory systems of the brain. The authors conceptualize these memory systems from both behavioral and neurobiological perspectives.

Sara T. Fry maintains that care is a central concept for nursing ethics. This requires, among other things, that care is a virtue rather than a mode of being. But if care is a central virtue of ethics and medical ethics then the claim that care is a central concept for nursing ethics is trivial. Otherwise, it is implausible.

In the Lysis, Socrates argues that friendship is driven by a desire to use others for one’s own gain. Some commentators take Socrates to be speaking for Plato on this point. By contrast, I shall argue that the Lysis is a reductio ad absurdum of this instrumental account of friendship. First, three arguments in the Lysis reach counterintuitive conclusions which may be avoided by abandoning the common premise that friendship is instrumental. Second, the dramatic context includes counterexamples to the instrumental (...) account of friendship. Third, Socrates distinguishes between people who are desirable because they are useful, and “true friends” who are desirable for their own sake. This is an explicit rejection of the instrumental account of friendship. (shrink)

The Institutional Animal Care and Use Committee is entrusted with assessing the ethics of proposed projects prior to approval of animal research. The role of the IACUC is detailed in legislation and binding rules, which are in turn inspired by the Three Rs: the principles of Replacement, Reduction, and Refinement. However, these principles are poorly defined. Although this provides the IACUC leeway in assessing a proposed project, it also affords little guidance. Our goal is to provide procedural and philosophical clarity (...) to the IACUC without mandating a particular outcome. To do this, we analyze the underlying logic of the Three Rs and conclude that the Three Rs accord animals moral standing, though not necessarily “rights” in the philosophical sense. We suggest that the Rs are hierarchical, such that Replacement, which can totally eliminate harm, should be considered prior to Reduction, which decreases the number of animals harmed, with Refinement being considered last. We also identify the need for a hitherto implicit fourth R: Reject, which allows the IACUC to refuse permission for a project which does not promise sufficient benefit to offset the pain and distress likely to be caused by the proposed research.

In I 7 Aristotle lays down criteria for what is to count as human happiness. Happiness for man is self-sufficient, complete without qualification, peculiar to humans, excellent, and best and most complete. Many interpreters agree that in X 6–8 Aristotle uses these along with other criteria to disqualify the life of amusement and rank one happy life above another.

Howard J. Curzer - Aristotle's Painful Path to Virtue - Journal of the History of Philosophy 40:2 Journal of the History of Philosophy 40.2 141-162 Aristotle's Painful Path to Virtue Howard J. Curzer [P]unishment . . . is a kind of cure . . . . We think young people should be prone to shame . . . . 1. Two Questions FOR ARISTOTLE, THE GOAL OF MORAL development is, of course, to become virtuous. Aristotle provides a partial (...) description of the virtuous person in the following familiar passage. The virtuous person performing virtuous acts, must have knowledge, secondly he must choose the acts, and choose them for their own sakes, and thirdly his actions must proceed from a firm and unchangeable character. By my count, this passage lists five components of virtue. Presumably, the virtuous agent's knowledge consists in true beliefs concerning which acts are virtuous plus a correct account of why they are virtuous. Virtue thus includes both the ability to identify which acts are virtuous in a given situation and an understanding of why they are virtuous. Choice is deliberate desire, so choosing virtuous acts is a combination of determining and desiring virtuous acts. People want to carry out virtuous acts for various reasons. For example, some choose virtuous acts merely because they are fashionable or instrumentally valuable. But Aristotle specifies that the virtuous person desires virtuous acts for their.. (shrink)

Akratic agents know what is best, can do it, do not do it, and rationalize. According to Socrates, seemingly akratic agents are confused, ignorant of what is best. According to the Many, they are overcome, unable to do what is best. Unlike Socrates and the Many, Plato rejects hedonism and psychological egoism, but not the existence of akratic acts in the Socratic reductio. Counterexamples to both Socrates’ mismeasure account and the Many’s overpowering account pervade Greek literature and even the Protagoras (...) itself. In the courage-is-wisdom arguments, Plato again argues against hedonism and psychological egoism, and advances an Aristotelian definition of courage. (shrink)

Once again it is becoming fashionable to ask ‘What character traits are virtues?’ Naturally, it behooves us to try to recapture the insights of our predecessors, as well as forging ahead on our own. In this paper I shall examine one such insight.

Is torturing innocent people ever morally required? I rebut responses to the ticking-bomb dilemma by Slote, Williams, Walzer, and others. I argue that torturing is morally required and should be performed when it is the only way to avert disasters. In such situations, torturers act with dirty hands because torture, though required, is vicious. Conversely, refusers act wrongly, yet virtuously, thus displaying admirable immorality. Vicious, morally required acts and virtuous, morally wrong acts are odd, yet necessary to preserve the ticking-bomb (...) dilemma’s phenomenology, the role of habituation in moral development, the virtue/continence distinction, and morality’s overridingness, consistency, and plausibility.

The article argues that Aristotle takes the mean to be relative neither to character nor to social role, but simply to the agent’s situation. The “character relativity” interpretation arises from the contemporary common-sense impulse to hold people who must overcome obstacles to a lower standard than people who easily act and feel rightly. However, character relativity vitiates Aristotle’s distinction between what moral people should do and what people should do to become moral. It also clashes with Aristotle’s principle that the (...) virtuous person is the measure of which actions and passions are virtuous. The “role relativity” interpretation arisesfrom the contemporary common-sense impulse to hold people in different social roles to different standards. However, role relativity vitiates Aristotle’s distinctionbetween the good person, on the one hand, and the good ruler, subject, doctor, soldier, and citizen, on the other. It also clashes with his claim that children, natural slaves, and women are inferior to adult, naturally free men. (shrink)

I consider a familiar argument for two-boxing in Newcomb's Problem and find it defective because it involves a type of divergence from standard Baysian reasoning, which, though sometimes justified, conflicts with the stipulations of the Newcomb scenario. In an appendix, I also find fault with a different argument for two-boxing that has been presented by Graham Priest.

Vallor lists and describes seven complex features of moral self-cultivation shared by Aristotelian, Confucian, and Buddhist traditions, a dozen virtues which technology renders particularly important, and seven threats to these virtues. Responding to one of Vallor’s challenges, I offer eight ways in which these virtues must be transformed in light of our technology. Finally, I list four further challenges to virtue ethics posed by technology.

This paper represents an attempt to analyze the basis for the lack of interest and study in the sociology of science within American sociology and within American society. An attempt is first made to indicate the divergence between the meta-sociology of the sociologist of knowledge and contemporary American sociology; and in a derivative manner to indicate the way in which divergent meta-sociologies may lead to different claims about the relationship of science and society. Secondly, an attempt is made to show (...) how the prestige position of the sociologist and the clarity of his status with regard to natural science may also be construed as grounds for the neglect of this field of inquiry.

The domestic legal obstacles to affirmative action to address the problem of the color line that have arisen in the United States in the past 30 years have become the occasion for discouragement and even despair in the face of the persistent racial disparities in American life. This is due, in part, to the limits of our domestic vocabulary for speaking about such initiatives. In this paper I argue that Christian ethics, with the help of the resources of the emergent (...) minority rights dialogue in international human rights, can play an important role in securing the cultural transformation needed to broaden our vocabulary and reframe our thinking so that our efforts to secure racial justice are not bound by the limits of the conventional domestic vocabulary. Specifically, I argue that the new international discussion of "the right to self-determination" can be usefully employed within Christian ethics to secure the cultural, moral and legal changes needed to secure racial justice in the United States.

Animal research in laboratories is currently informed by the three R’s (Replacement, Reduction, and Refinement), a common-sense theory of animal research ethics. In addition a fourth R (Refusal) is needed to address research plans that are so badly conceived that their chances of gaining any knowledge worth the animal suffering they cause are nil. Unfortunately, these four R’s do not always yield workable solutions to the moral problems faced regularly by wildlife researchers. It is possible to develop analogs in the (...) sphere of environmental research to these four R’s, creating a common-sense theory of environmental research ethics that will provide significant guidance to researchers and win acceptance from almost all stakeholders. This theory can be articulated in terms of twenty basic principles. (shrink)
