This paper considers the disciplines of literature and history and the contributions each makes to the discourse of bioethics. In each case I note the pedagogic ends that can be enacted though the appropriate use of the each of these disciplines in the sphere of medical education, particularly in the medical ethics classroom.1 I then explore the contribution that both these disciplines and their respective methodologies can and do bring to the academic field of bioethics. I conclude with a brief (...) consideration of the relations between literature and history with particular attention to the possibilities for a future bioethics informed by history and literature after the empirical turn.

This paper considers the utility of Ethnomethodology (EM) for the study of healthcare ethics as part of the empirical turn in Bioethics. I give a brief introduction to EM through its respecification of sociology, the specific view on the social world this generates and EM's posture of ‘indifference’. I then take a number of EM concepts and articulate each in the context of an EM study of healthcare ethics in professional practice. Having given an overview of the relationship and perspective (...) EM might bring to the professional practice of healthcare ethics I consider whether and how such an approach could be deployed. Whilst an ethnographic study might be problematic I suggest a number of alternative methods through which such EM research could be accomplished. I conclude with the suggestion that, as a particular approach to sociological research, EM offers good deal of potential for the empirical study of healthcare ethics in practice which could result in an improved reflexive understanding of professional ethical practices in bioethics.

Are any of our beliefs justified? Are they rational? The skeptic thinks that our epistemic justifications are undeserved. Nicholas Nathan confronts the skeptic and questions the value of his argument. Skeptical arguments are against justified and rational belief as well as for ignorance. Nathan argues that the truth value of trivial arguments are a matter of indifference. He tests this conjecture with a varied collection of counterexamples: arguments for ignorance, neo-Cartesian and infinite regress arguments, and also more critically (...) with arguments against justified and rational belief.

A systematic study of rational or justified belief, which throws fresh light on current debates about foundations and coherence theories of knowledge, the validation of induction and moral scepticism. Dr Nathan focuses attention on the largely unsatisfiable desires for active and self-conscious assurance of truth liable to be engendered by philosophical reflection about total belief-systems and the sources of knowledge. He extracts a kernel of truth from the doctrine that a regress of justification is both necessary and impossible, contrasts (...) the resultant scepticism with more familiar complaints about the inapplicability of supposedly essential cognitive concepts and explores the feasibility of non-Humean modes of consolation. This is an original and carefully constructed book, which will interest professional philosophers and advanced students of epistemology. (shrink)
Beneath metaphysical problems there often lies a conflict between what we want to be true and what we believe to be true. Nathan provides a general account of the resolution of this conflict as a philosophical objective, showing that there are ways of thinking it through systematically with a view to resolving or alleviating it. The author also studies in detail a set of interrelated conflicts about the freedom and the reality of the will. He shows how difficult it (...) is to find a freedom either of decision or of action which is both an object of reflective desire and an object of rational belief. He also examines conflicts about volition as such, contending that the veridicality of volitional experience is no less easy to doubt than the veridicality of our experience of colors. In this context, arguments emerge for a voluntarist theory of the self. Nathan's important book will be essential reading for all philosophers interested in free will, volition, the self, and the methodology of metaphysics. (shrink)
Direct Realists believe that perception involves direct awareness of an object not dependent for its existence on the perceiver. Howard Robinson rejects this doctrine in favour of a Sense-Datum theory of perception. His argument against Direct Realism invokes the principle ‘same proximate cause, same immediate effect’. Since there are cases in which direct awareness has the same proximate cerebral cause as awareness of a sense datum, the Direct Realist is, he thinks, obliged to deny this causal principle. I suggest that (...) although Direct Realism is in more than one respect implausible, it does not succumb to Robinson’s argument. The causal principle is true only if ‘proximate cause’ means ‘proximate sufficient cause’, and the Direct Realist need not concede that there is a sufficient cerebral cause for direct awareness of independent objects.

There is an apparent problem in identifying a basis for equality. This problem vanishes if what I call the ‘intuited response’ is successful. According to this response, there is no further explanation of the significance of the feature in virtue of which an individual matters, beyond the bare fact that it is the feature in virtue of which an individual matters. I argue against this claim, and conclude that if the problem of identifying a basis for equality is to be (...) resolved, it is necessary to defend a substantive account of the independent significance of some feature.

Some Christians combine a doctrine about Christ which implies that there is more than one divine self with the doctrine that God revealed to the Jews a monotheism according to which there is just one divine self. I suggest that it is less costly for such Christians to achieve consistency by abandoning the second of these doctrines than to achieve it by abandoning the first.
In "Warrant and Proper Function" Plantinga argues that atheistic Naturalism is self-defeating. What is the probability that our cognitive faculties are reliable, given this Naturalism and an evolutionary explanation of their origins? Plantinga argues that if the Naturalist is modest enough to believe that it is irrational to have any belief as to the value of this probability, then he is irrational even to believe his own Naturalism. I suggest that Plantinga's argument has a false premise, and that even if (...) his argument were sound there would be reasons for doubting whether the Naturalist should respond to it by abandoning his Naturalism.

This essay is concerned with concentrations of entities, which play an important—albeit often overlooked—role in scientific explanation. First, I discuss an example from molecular biology to show that concentrations can play an irreducible causal role. Second, I provide a preliminary philosophical analysis of this causal role, suggesting some implications for extant theories of causation. I conclude by introducing the concept of causation by concentration, a form of statistical causation whose widespread presence throughout the sciences has been unduly neglected and which (...) deserves to be studied in more depth. 1 Introduction2 Solving Lillie's Paradox: Lysogenic Induction in Phage λ3 Repressor Concentration and the Tuning of the Switch4 Concentration and Causality5 Preemption in Concentrations: Analysis and Implications6 Causation by Concentration: General Definition, Refinements, and Further Applications.

While philosophers tend to consider a single type of causal history, biologists distinguish between two kinds of causal history: evolutionary history and developmental history. This essay studies the peculiarity of development as a criterion for the individuation of biological traits and its relation to form, function, and evolution. By focusing on examples involving serial homologies and genetic reprogramming, we argue that morphology (form) and function, even when supplemented with evolutionary history, are sometimes insufficient to individuate traits. Developmental mechanisms bring in (...) a novel aspect to the business of classification—identity of process-type—according to which entities are type-identical across individuals and natural kinds in virtue of the fact that they form and develop through similar processes. These considerations bear important metaphysical implications and have potential applications in several areas of philosophy. (shrink)
‘Probability dynamics’ (PD) is a second-order probabilistic theory in which probability distribution d X = (P(X 1), . . . , P(X m )) on partition U m X of sample space Ω is weighted by ‘credence’ (c) ranging from −∞ to +∞. c is the relative degree of certainty of d X in ‘α-evidence’ α X =[c; d X ] on U m X . It is shown that higher-order probabilities cannot provide a theory of PD. PD applies to (...) both subjectivist and frequentist theories. ‘Straight PD’ (SPD) produces associative and commutative mergers of evidence, in which evidences of positive credence are mutually reinforcing. ‘Offsetting PD’ (OPD) sets off conflicting evidences against each other. Subjectivist PD is a quantified second-order logic of action. Frequentist PD relates to descriptions of physical states of affairs. Acceptance of evidence α 1 X = [c 1; d 1 X ] at t 1 updates α 0 X = [c 0; d 0 X ] at t 0 into SPD-merger or OPD-merger . Given ‘co-evidence’ at t 0 < t 1, ‘indirect’ PD accepts evidence at t 1 and produces support for update α 10 X = [c10;d 10 X α 0 X such that in SPD and in OPD. For binary X and Y, with α 0 X = [c 0; P 0(X)] at t 0 (short-hand for ) and the accepted evidence, the support is ; ; where ρ0(X, Y) is the correlation coefficient of X and Y, and update α 10 X of α 0 X is with ‘accord’ λ = 1 in SPD and in OPD. As , tends toward update P 1(Y) of P 0(Y), but P 10(X) does not converge toward ‘ ’ of ‘probability kinematics’. Therefore PD is not compatible with probability kinematics. A process of ‘normalization’ interprets ‘β-evidence’ [[c 1; q 1]& . . . &[c m ; q m ]; U m X ]] with [c j ; q j ] on and m ≥ 3, as an α-evidence on {X 1, . . . , X m }. It is shown that SPD- and OPD-updates can be derived from updated cumulative functions. Time-biased updates are discussed. A PD-based theory of confirmation (PDCT) is presented. (shrink)
Disgust or horror is our natural attitude to eating human flesh and drinking human blood. How can this attitude not transfer itself to the Christian Eucharist, in which the bread is said to be Christ's body and the wine his blood? And if the aversion must transfer itself, then how can God have been, as Christians have to think, the founder of the rite? I discuss these questions with reference to several different theories of the Eucharist, one Calvinist, the others (...) of a would-be Roman Catholic kind. (shrink)
Common probabilistic fallacies and putative paradoxes are surveyed, including those arising from distribution repartitioning, from the reordering of expectation series, and from misconceptions regarding expected and almost certain gains in games of chance. Conditions are given for such games to be well-posed. By way of example, Bernoulli's "Petersburg Paradox" and Hacking's "Strange Expectations" are discussed and the latter are resolved. Feller's generalized "fair price, in the classical sense" is critically reviewed.
Jaynes contends that in many statistical problems a seemingly indeterminate probability distribution is made unique by the transformation group of necessarily implied invariance properties, thereby justifying the principle of indifference. To illustrate and substantiate his claims he considers Bertrand's Paradox. These assertions are here refuted and the traditional attitude is vindicated.
Six recently discussed problems in discrete probabilistic sample space, which have been found puzzling and even paradoxical, are reexamined. The importance is stressed of a sharp distinction between the formalization of mathematical problems and their formal solution that, applied to probability theory, must lead through the explicit partitioning of a sample space. If this approach is consistently followed, such problems reveal themselves to be either inherently ambiguous, and therefore without solution, or quite straightforward. In both cases nothing remains of any (...) sense of paradox. (shrink)
When do two mental items belong to the same life? We could be content with the answer -just when they have certain volitional qualities in common. An affinity is noted between that theory and Berkeley's early doctrine of the self. Some rivals of the volitional theory invoke a spiritual or physical owner of mental items. They run a risk either of empty formality or of causal superstition. Other rivals postulate a non-transitive and symmetrical relation in the set of mental items. (...) They must allow in consequence either for joint ownership of one and the same mental item, or for incompatible simultaneous decisions by one and the same person, or for new forms of death. This makes them disquieting. Another rival invokes a transitive and symmetrical relation defined in terms of co-consciousness. Even that allows for incongruous simultaneities. The volitional theory is free from such disadvantages. (shrink)
An empirical law or evidence which supports a theory tends to have the greatest scientific value when it seemed improbable before it was investigated. Evidence which falsifies a theory tends to have the greatest value when it seemed probable that the investigation would confirm the theory. A scientist who wishes to optimize his contribution to knowledge probably will investigate most frequently hypotheses which seem neither very probable nor very improbable of being confirmed. This strategy leads neither to a maximum number (...) of confirmations of a theory, nor to a set of tests which are maximally severe. (shrink)
After briefly vindicating casuistries which successively apply a number of different moral principles, I describe some of the principles of justice liable to figure in such casuistries, assess the relative popularity of these principles and show that some of the most popular cannot be consistently applied in all circumstances.
Nicholas Nathan tries to resist the current version of the causal argument for sense-data in two ways. First he suggests that, on what he considers to be the correct reconstruction of the argument, it equivocates on the sense of proximate cause. Second, he defends a form of disjunctivism, by claiming that there might be an extra mechanism involved in producing veridical hallucination that is not present in perception. I argue that Nathan’s reconstruction of the argument is not the (...) appropriate one, and that, properly interpreted, the argument does not equivocate on proximate cause. Furthermore, I claim that his postulation of a modified mechanism for hallucinations is implausibly ad hoc. (shrink)
1. Nathan Salmon paper is entitled with a question: are general terms rigid? He asks this question in way of engaging the issue of the extension of the notion of rigidity beyond the domain of singular terms. While singular terms has been the province of most of the discussion of this rigidity since Naming and Necessity, it is well known that Kripke saw the notion extending to at least certain general terms such as terms for natural kinds. Scott Soames (...) has recently weighed in on this issue in the latter chapters of his book Beyond Rigidity. His conclusion is that although there are significant overlaps in the properties of singular and general terms, there is no direct extension of rigidity to the general terms, and that rigid designation is properly applied only to singular terms. Salmon disagrees. His view, based in part of views dating back to his book Reference and Essence, is that there is an extension to be had, one which allows the application of the standard Kripkean characterization of rigidity to be applied to both sorts of terms. Central to his thesis is a claim about the status of certain definite descriptions. In these remarks, I will try to outline the issues to which NS is reacting, and the proposal he posits in response. I will then consider in a more critical light his claim about definite descriptions, bringing to bear considerations of their grammar. (shrink)
Pinn seems to be addressing two logically distinct sets of questions. They are distinct in that answers to one set have no implications for the other (or if they do, the [1] connection is not at all obvious). It’s not clear whether Pinn realizes this.
I very much appreciate Daniel Nathan’s thoughtful commentary on Aesthe- tic Creation. He describes my view accurately, with a full understanding of what is moving me, and with some sympathy for my methodological concerns, even if he thinks that I over emphasize some desiderata and even if he cannot endorse the particular aesthetic theory that I argue emerges from the methodological reflections. He makes a number of interesting criticisms. (A) Nathan worries about doodles being classified as art according (...) the aesthetic creation theory. Nathan says that this violates certain intuitions about the nature of art. I query this appeal to intuition. Whose concepts? Which intuitions? Why do such intuitions have evidential weight? We have intuitions abut the physical world: that the earth is flat not round. More to the point we have intuitions about kinds. For example, it is intuitive that a whale is a fish. But such intuitions may be mistaken. Similarly with intuitions about what is art and what is not art. With intuitions I say at least that there is, or should be, a question mark standing over them. We are interested in the world, not in our concepts or intuitions. The question is: what are these things? And the question about concepts is: which do we need to understand the things? Which concepts should we have? Not: which do we have? As Nathan notes, for me, explanation trumps extension if there is a conflict. Or perhaps rather, for me, extension is subsumed under explanation. It is true that there are avant garde works that I exclude that other theories include. And there also are doodles that I include and they exclude. The question is where we go from there. (B) Nathan worries about the success condition. I required that to some extent artists are right about aesthetic/nonaesthetic dependencies. Actually, I would not kill for the success condition. Perhaps aesthetic intent is enough1. A person might form an aesthetic intention but never get round to acting on it, in which case we do not have a work of art.. (shrink)
This is a response to a paper by N.M.L. Nathan in which he argues that the attempt to provide a global justification of our entire set of beliefs necessarily leads to an infinite regress, in contrast with cases of local uncertainty, which he thinks can be resolved without regress. I argue that if he is right about the local uncertainty case, then he should not fear a regress in the global case, as the two situations are more similar than (...) he supposes. (shrink)
