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.

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 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.

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)

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.

How does trust relate to faith? We do not know of a theory-neutral way to answer our question. So, we begin with what we regard as a plausible theory of faith according to which, in slogan form, faith is resilient reliance. Next, we turn to contemporary theories of trust. They are not of one voice. Still, we can use them to indicate ways in which trust and faith might both differ from and resemble each other. This is what we do. (...) Along the way, we evaluate substantive issues related to these possible differences and similarities. (shrink)

We assess John Bishop’s theory of the nature of Christian faith in God, as most recently expressed in ‘Reasonable Faith and Reasonable Fideism’, although we dip into other writings as well. We explain several concerns we have about it. However, in the end, our reflections lead us to propose a modified theory, one that avoids our concerns while remaining consonant with some of his guiding thoughts about the nature of Christian faith in God. We also briefly examine three normative issues (...) Bishop’s views present. (shrink)

John Howard Whitehouse was a British educationalist, social reformer and the founder of Bembridge School on the Isle of Wight. In this book, which was first published in 1928, Whitehouse provides a concise account of life at Bembridge and the methods employed by the school. A vision is put forward in which, without compromising more conventionally academic areas, arts and crafts are presented as being central to the process of 'spiritual and intellectual education'. Numerous illustrative figures are also included, (...) revealing aspects of life at the school and works created by the students. This book will be of value to anyone with an interest in the ideas of Whitehouse and the history of education. (shrink)

Can faith be valuable and, if so, under what conditions? We know of no theory-neutral way to address this question. So, we offer a theory of relational faith, and we supplement it with a complementary theory of relational faithfulness. We then turn to relationships of mutual faith and faithfulness with an eye toward exhibiting some of the ways in which, on our theory, faith and faithfulness can be valuable and disvaluable. We then extend the theory to other manifestations of faith (...) and faithfulness, propose a way to unify them under a theory of faith and faithfulness simpliciter, and explain how they can be neo-Aristotelian virtues and vices. We close with our solution to the value problem and avenues for further research. (shrink)

Source credibility has been thought to bean important determinant of peoples‘ reactions toinformation about technology. There has also been muchdebate about the need to communicate effectively withthe public about genetic engineering, particularlywithin the context of food production. Questionnaireswere used to investigate the impact of sourcecredibility, admission of risk uncertainty, andinitial attitude towards genetic engineering onattitudes of respondents after information provision.120 respondents with positive attitudes towardsgenetic engineering in food production were providedwith persuasive information about the technology,where both source attribution and admission (...) of riskuncertainty were systematically varied within theexperimental design. Impact on perceptions of sourcecredibility, informational qualities, and postintervention attitudes were examined, and compared toa second group of respondents who held initiallynegative attitudes towards genetic engineering, andwho had been exposed to similar informationinterventions. As predicted by Social Judgment Theory,initial attitude was found to be an importantdeterminant of post-intervention attitude. However,admission of risk uncertainty was also found to beinfluential in increasing acceptance and reducingrejection of the technology, possibly through thefacilitation of elaborative processing. Contrary toprevious research, prior attitudes had an impact onperceptions of both source credibility andinformational quality. In terms of effectiveinformation provision about genetic engineering, itwas concluded that scientific honesty is the bestpolicy, and that lay understanding of scientificprocess is probably greater than hitherto assumed byexperts.

It is common for young Christians to go off to college assured in their beliefs but, in the course of their first year or two, they meet what appears to them to be powerful defenses of scientific naturalism and crushing critiques of the basic Christian story (BCS), and many are thrown into doubt. They think to themselves something like this: "To be honest, I am troubled about the BCS. While the problem of evil, the apparent cultural basis for the diversity (...) of religions, the explanatory breadth of contemporary science, naturalistic explanations of religious experience and miracle reports, and textual and historical criticism of the Bible, among other things, don’t make me believe the BCS is false , I am in serious doubt about it, so much so that I lack belief of it. In that case, how can I have Christian faith? And if I don’t have faith, how can I keep on praying, attending church, affirming the creed, confessing my sins, taking the sacraments, singing the hymns and songs, and so on? I can’t, unless I’m a hypocrite. So integrity requires me to drop the whole thing and get out." Of course, our student is not alone. Many Christians find themselves for some portion of their lives somewhere on the trajectory from doubt to getting out. Indeed, Christians in the West struggle with intellectual doubt more than they used to, especially university-educated Christians. What should we say to them? Some will say “Get out!,” welcoming the development as a path to liberation. We explore a different response in this essay. (shrink)

In his Truth and Probability (1926), Frank Ramsey provides foundations for measures of degrees of belief in propositions and preferences for worlds. Nonquantitative conditions on preferences for worlds, and gambles for worlds and certain near-worlds, are formulated which he says insure that a subject's preferences for worlds are represented by numbers, world values. Numbers, for his degrees of belief in propositions, probabilities, are then defined in terms of his world values. Ramsey does not also propose definitions of desirabilities for propositions, (...) though he is in a position to do this. Given his measures for probabilities of propositions and values of worlds, he can frame natural definitions for both evidential and causal desirabilities that would measure respectively the welcomeness of propositions as items of news, and as facts. His theory is neutral with respect to the evidential/causal division. In the present paper, as Ramsey's foundations are explained, several problems and limitations are noted. Their distinctive virtue – their evidential/causal neutrality – is demonstrated. Comparisons are made with other foundational schemes, and a perspective is recommended from which nonquantitative foundations are not the be all for quantitative theories of ideal preferences and credences.

This is a wide-ranging 2004 book about arguments for and against beliefs in God. The arguments for the belief are analysed in the first six chapters and include ontological arguments from Anselm to Gödel, the cosmological arguments of Aquinas and Leibniz, and arguments from evidence for design and miracles. The next two chapters consider arguments against belief. The last chapter examines Pascalian arguments for and against belief in God. There are discussions of Cantorian problems for omniscience, of challenges to divine (...) omnipotence, and of the compatibility of everlasting complete knowledge of the world with free-will. There are appendices that present formal proofs in a system for quantified modal logic, a theory of possible worlds, notes on Cantorian set theory, and remarks concerning non-standard hyperreal numbers. This book will be a valuable resource for philosophers of religion and theologians and will interest logicians and mathematicians as well. (shrink)

We study statements about countable and well-ordered unions and their relation to each other and to countable and well-ordered forms of the axiom of choice. Using WO as an abbreviation for “well-orderable”, here are two typical results: The assertion that every WO family of countable sets has a WO union does not imply that every countable family of WO sets has a WO union; the axiom of choice for WO families of WO sets does not imply that the countable union (...) of countable sets is WO.

We argue that Parfit's "Triviality Objection" against some naturalistic views of normativity is not compelling. We think that once one accepts, as one should, that identity statements can be informative in virtue of their pragmatics and not only in virtue of their semantics, Parfit's case against naturalism can be overcome.

When causal decision theory was created in the 1970s, access to Howard Sobel’s contribution was available only in a narrowly circulated mimeographed manuscript. After some time, he allowed his ideas to appear in the form of articles. Here we finally have a book length exposition on Sobel’s causal Bayesian point of view consisting of collected, revised, and amplified papers spanning a period of twenty years.

A BAYESIAN ARTICULATION OF HUME’S VIEWS IS OFFERED BASED ON A FORM OF THE BAYES-LAPLACE THEOREM THAT IS SUPERFICIALLY LIKE A FORMULA OF CONDORCET’S. INFINITESIMAL PROBABILITIES ARE EMPLOYED FOR MIRACLES AGAINST WHICH THERE ARE ’PROOFS’ THAT ARE NOT OPPOSED BY ’PROOFS’. OBJECTIONS MADE BY RICHARD PRICE ARE DEALT WITH, AND RECENT EXPERIMENTS CONDUCTED BY AMOS TVERSKY AND DANIEL KAHNEMAN ARE CONSIDERED IN WHICH PERSONS TEND TO DISCOUNT PRIOR IMPROBABILITIES WHEN ASSESSING REPORTS OF WITNESSES.

Two partition-theorems are proved for a particular causal decision theory. One is restricted to a certain kind of partition of circumstances, and analyzes the utility of an option in terms of its utilities in conjunction with circumstances in this partition. The other analyzes an option's utility in terms of its utilities conditional on circumstances and is quite unrestricted. While the first form seems more useful for applications, the second form may be of theoretical importance in foundational exercises. Comparisons are made (...) with theorems of Richard Jeffrey, Brad Armendt, and Peter Fishburn. (shrink)

According to a familiar argument, iterated prisoner's dilemmas of known finite lengths resolve for ideally rational and well-informed players: They would defect in the last round, anticipate this in the next to last round and so defect in it, and so on. But would they anticipate defections even if they had been cooperating? Not necessarily, say recent critics. These critics "lose" the backward-induction paradox by imposing indicative interpretations on rationality and information conditions. To regain it I propose subjunctive interpretations. To (...) solve it I stress that implications for ordinary imperfect players are limited. (shrink)

Rational actions reflect beliefs and preferences in certain orderly ways. The problem of theory is to explain which beliefs and preferences are relevant to the rationality of particular actions, and exactly how they are relevant. One distinction of interest here is between an agent's beliefs and preferences just before an action's time, and his beliefs and preferences at its time. Theorists do not agree about the times of beliefs and desires that are relevant to the rationality of action. Another distinction (...) is between actions that would, in one sense or another, maximize expected utilities given relevant beliefs and desires, and actions, decisions for which would, in one sense or another, be stable. There is disagreement about the relevance of these things to the rationality of actions. Here, in the first part below, several possible positions on these issues are explained and compared. In the second part, I contrast perspectives on these issues, and comment on arguments that might be brought against the position I favor. In the third part, I restate and elaborate on this position.
