Recent writing on the idea of a form of life has tended to be critical of the use made of this notion by writers such as Peter Winch, D. Z. Phillips and Norman Malcolm. Rightly or wrongly these writers have been regarded as meaning by ‘a form of life’, something like ‘a way or style of life’, and recent explicatory work on the notion has largely tended to discount this as a plausible interpretation of what Wittgenstein meant in his (...) use of the expression. The intention of this paper is not that of direct intervention in this particular dispute, though the conclusions drawn, if correct, would have some bearing on it. The intention is rather to develop, in order to make use of it, the idea of a form of life within the context of a number of philosophical difficulties. I should certainly claim to be drawing upon the remarks made by Wittgenstein in his own use of the expression: but I should not claim to be expounding Wittgenstein. Hence I do not wish to enter into the disputes referred to above about what precisely Wittgenstein meant by the expression, though again, what I say, if not wholly misguided, should have some bearing on these disputes.

Traditional analyses of the curve fitting problem maintain that the data do not indicate what form the fitted curve should take. Rather, this issue is said to be settled by prior probabilities, by simplicity, or by a background theory. In this paper, we describe a result due to Akaike [1973], which shows how the data can underwrite an inference concerning the curve's form based on an estimate of how predictively accurate it will be. We argue that this approach throws light (...) on the theoretical virtues of parsimoniousness, unification, and non ad hocness, on the dispute about Bayesianism, and on empiricism and scientific realism. * Both of us gratefully acknowledge support from the Graduate School at the University of Wisconsin-Madison, and NSF grant DIR-8822278 (M.F.) and NSF grant SBE-9212294 (E.S.).

Scientific discovery is often regarded as romantic and creative - and hence unanalyzable - whereas the everyday process of verifying discoveries is sober and more suited to analysis. Yet this fascinating exploration of how scientific work proceeds argues that however sudden the moment of discovery may seem, the discovery process can be described and modeled. Using the methods and concepts of contemporary information-processing psychology (or cognitive science) the authors develop a series of artificial-intelligence programs that can simulate the human thought (...) processes used to discover scientific laws. The programs - BACON, DALTON, GLAUBER, and STAHL - are all largely data-driven, that is, when presented with series of chemical or physical measurements they search for uniformities and linking elements, generating and checking hypotheses and creating new concepts as they go along. "Scientific Discovery examines the nature of scientific research and reviews the arguments for and against a normative theory of discovery; describes the evolution of the BACON programs, which discover quantitative empirical laws and invent new concepts; presents programs that discover laws in qualitative and quantitative data; and ties the results together, suggesting how a combined and extended program might find research problems, invent new instruments, and invent appropriate problem representations. Numerous prominent historical examples of discoveries from physics and chemistry are used as tests for the programs and anchor the discussion concretely in the history of science.

This third installment in David Breed's intellectual biography of Ralph Wendell Burhoe focuses upon the impact of his thought on the Unitarian Universalist Association and that group's role in Burhoe's career. Dana McLean Greeley, elected president of the American Unitarian Association in 1958, was a key figure in Burhoe's eventual participation in the project, “The Free Church in a Changing World.” Burhoe's emphasis on the need for doctrine that could communicate religious wisdom in terms of science stood in tension with (...) free‐church tradition. Nevertheless, the section of the project's final report, titled “Theology and the Frontiers of Learning,” largely accepted Burhoe's program for a new natural theology based on science. This project brought Burhoe's program to the attention of the denomination and led to the invitation in 1964 from Malcolm Sutherland, on behalf of Meadville/Lombard Theological School in Chicago, of which he was president, for Burhoe to implement his program in the new curriculum of that school. Burhoe accepted. (shrink)

William Whewell’s philosophy of scientific discovery is applied to the problem of understanding the nature of unification and explanation by the composition of causes in Newtonian mechanics. The essay attempts to demonstrate: the sense in which ”approximate’ laws successfully refer to real physical systems rather than to idealizations of them; why good theoretical constructs are not badly underdetermined by observation; and why, in particular, Newtonian forces are not conventional and how empiricist arguments against the existence of component causes, and against (...) the veracity of the fundamental laws, are flawed.

The simple question, what is empirical success? turns out to have a surprisingly complicated answer. We need to distinguish between meritorious fit and ‘fudged fit', which is akin to the distinction between prediction and accommodation. The final proposal is that empirical success emerges in a theory dependent way from the agreement of independent measurements of theoretically postulated quantities. Implications for realism and Bayesianism are discussed. ‡This paper was written when I was a visiting fellow at the Center for Philosophy of (...)

What has science actually achieved? A theory of achievement should define what has been achieved, describe the means or methods used in science, and explain how such methods lead to such achievements. Predictive accuracy is one truth‐related achievement of science, and there is an explanation of why common scientific practices tend to increase predictive accuracy. Akaike’s explanation for the success of AIC is limited to interpolative predictive accuracy. But therein lies the strength of the general framework, for it also provides (...) a clear formulation of many open problems of research. (shrink)

Sober (1984) has considered the problem of determining the evidential support, in terms of likelihood, for a hypothesis that is incomplete in the sense of not providing a unique probability function over the event space in its domain. Causal hypotheses are typically like this because they do not specify the probability of their initial conditions. Sober's (1984) solution to this problem does not work, as will be shown by examining his own biological examples of common cause explanation. The proposed solution (...) will lead to the conclusion, contra Sober, that common cause hypotheses explain statistical correlations and not matchings between event tokens. (shrink)

The theory of fast and frugal heuristics, developed in a new book called Simple Heuristics that make Us Smart (Gigerenzer, Todd, and the ABC Research Group, in press), includes two requirements for rational decision making. One is that decision rules are bounded in their rationality –- that rules are frugal in what they take into account, and therefore fast in their operation. The second is that the rules are ecologically adapted to the environment, which means that they `fit to reality.' (...) The main purpose of this article is to apply these ideas to learning rules–-methods for constructing, selecting, or evaluating competing hypotheses in science, and to the methodology of machine learning, of which connectionist learning is a special case. The bad news is that ecological validity is particularly difficult to implement and difficult to understand. The good news is that it builds an important bridge from normative psychology and machine learning to recent work in the philosophy of science, which considers predictive accuracy to be a primary goal of science.

Curve-fitting typically works by trading off goodness-of-fit with simplicity, where simplicity is measured by the number of adjustable parameters. However, such methods cannot be applied in an unrestricted way. I discuss one such correction, and explain why the exception arises. The same kind of probabilistic explanation offers a surprising resolution to a common-sense dilemma.

The likelihood theory of evidence (LTE) says, roughly, that all the information relevant to the bearing of data on hypotheses (or models) is contained in the likelihoods. There exist counterexamples in which one can tell which of two hypotheses is true from the full data, but not from the likelihoods alone. These examples suggest that some forms of scientific reasoning, such as the consilience of inductions (Whewell, 1858. In Novum organon renovatum (Part II of the 3rd ed.). The philosophy of (...) the inductive sciences. London: Cass, 1967), cannot be represented within Bayesian and Likelihoodist philosophies of science. (shrink)

Van Fraassen has argued that quantum mechanics does not conform to the pattern of common cause explanation used by Salmon as a precise formulation of Smart's 'cosmic coincidence' argument for scientific realism. This paper adds to this list some common examples from classical physics that also do not conform to Salmon's explanatory schema. This is bad news and good news for the realist. The bad news is that Salmon's argument for realism does not work; the good news is that realism (...) need not demand hidden variables in quantum mechanics if they are not used in classical mechanics. Many correlations in physics are explained in terms of property identity (contra Salmon). This leads to a new argument against van Fraassen because the unified version of the theory obtained by identifying theoretical properties is always less empirically adequate. (shrink)

The paper provides a formal proof that efficient estimates of parameters, which vary as as little as possible when measurements are repeated, may be expected to provide more accurate predictions. The definition of predictive accuracy is motivated by the work of Akaike (1973). Surprisingly, the same explanation provides a novel solution for a well known problem for standard theories of scientific confirmation — the Ravens Paradox. This is significant in light of the fact that standard Bayesian analyses of the paradox (...) fail to account for the predictive utility of universal laws like All ravens are black. (shrink)

Classical mechanics is empirically successful because the probabilistic mean values of quantum mechanical observables follow the classical equations of motion to a good approximation (Messiah 1970, 215). We examine this claim for the one-dimensional motion of a particle in a box, and extend the idea by deriving a special case of the ideal gas law in terms of the mean value of a generalized force used to define "pressure." The examples illustrate the importance of probabilistic averaging as a method of (...) abstracting away from the messy details of microphenomena, not only in physics, but in other sciences as well.

Skyrms's formulation of the argument against stochastic hidden variables in quantum mechanics using conditionals with chance consequences suffers from an ambiguity in its "conservation" assumption. The strong version, which Skyrms needs, packs in a "no-rapport" assumption in addition to the weaker statement of the "experimental facts." On the positive side, I argue that Skyrms's proof has two unnoted virtues (not shared by previous proofs): (1) it shows that certain difficulties that arise for deterministic hidden variable theories that exploit a nonclassical (...) probability theory extend to the stochastic case; (2) the use of counterfactual conditionals relates the Bell puzzle to Dummett's (1976) discussion of realism in quantum mechanics.

This paper aims to show how Whewell's notions of consilience and unification-explicated in more modern probabilistic terms provide a satisfying treatment of cases of scientific discovery Which require the postulatioin component causes to explain complex events. The results of this analysis support the received view that the increased unification and generality of theories leads to greater testability, and confirmation if the observations are favorable. This solves a puzzle raised by Cartwright in How the Laws of Physics Lie about the nature (...) of explanation by the composition of causes. (shrink)

Textbooks in quantum mechanics frequently claim that quantum mechanics explains the success of classical mechanics because “the mean values [of quantum mechanical observables] follow the classical equations of motion to a good approximation,” while “the dimensions of the wave packet be small with respect to the characteristic dimensions of the problem.” The equations in question are Ehrenfest’s famous equations. We examine this case for the one-dimensional motion of a particle in a box, and extend the idea deriving a special case (...) of the ideal gas law in terms of the mean value of a generalized force, which has been used in statistical mechanics to define ‘pressure’. The example may be an important test case for recent philosophical theories about the relationship between micro-theories and macro-theories in science. (shrink)

The Buddha taught a unique and verifiable method to end suffering in sentient beings. This is the eightfold noble path. But there are 84,000 discourses in which the Buddha describes just how one may come out of suffering. Is a seeker then expected to learn all these 84,000 discourses? Is there a shorter way out for the ardent meditator? There is. There is one discourse in particular that propounds the essence of the Buddha’s Teaching in crisp and clear terms. It (...) is the “Mahāsatipaṭṭhāna Sutta”. Its seminal importance is universally acknowledged. So, the next question that arises is: what is the core of the “Mahāsatipaṭṭhāna Sutta”? Which aspects of it are vital to one’s emancipation? A careful perusal of this discourse leads one to conclude that the Buddha repeatedly exhorts his monks to meditate in a particular manner. This involves three characteristics: Atāpi, Sampajāno and Satima. Of these, Atāpi is easy to understand: it means ardent, earnest, strenuous. The same holds for Satima. It means, in turn, with mindfulness or with awareness. It is Sampajāno which deserves our special attention, though. While it is essential to understand just what it means, its meaning is not so obvious. Once one does understand its meaning, its significance to the successful way out of ones own suffering becomes crystal clear. (shrink)

The central problem with Bayesian philosophy of science is that it cannot take account of the relevance of simplicity and unification to confirmation, induction, and scientific inference. The standard Bayesian folklore about factoring simplicity into the priors, and convergence theorems as a way of grounding their objectivity are some of the myths that Earman's book does not address adequately. 1Review of John Earman: Bayes or Bust?, Cambridge, MA.

BackgroundThe ARRIVE (Animal Research: Reporting of In Vivo Experiments) guidelines are widely endorsed but compliance is limited. We sought to determine whether journal-requested completion of an ARRIVE checklist improves full compliance with the guidelines.MethodsIn a randomised controlled trial, manuscripts reporting in vivo animal research submitted to PLOS ONE (March–June 2015) were randomly allocated to either requested completion of an ARRIVE checklist or current standard practice. Authors, academic editors, and peer reviewers were blinded to group allocation. Trained reviewers performed outcome adjudication (...) in duplicate by assessing manuscripts against an operationalised version of the ARRIVE guidelines that consists 108 items. Our primary outcome was the between-group differences in the proportion of manuscripts meeting all ARRIVE guideline checklist subitems.ResultsWe randomised 1689 manuscripts (control: n = 844, intervention: n = 845), of which 1269 were sent for peer review and 762 (control: n = 340; intervention: n = 332) accepted for publication. No manuscript in either group achieved full compliance with the ARRIVE checklist. Details of animal husbandry (ARRIVE subitem 9b) was the only subitem to show improvements in reporting, with the proportion of compliant manuscripts rising from 52.1 to 74.1% (X2 = 34.0, df = 1, p = 2.1 × 10−7) in the control and intervention groups, respectively.ConclusionsThese results suggest that altering the editorial process to include requests for a completed ARRIVE checklist is not enough to improve compliance with the ARRIVE guidelines. Other approaches, such as more stringent editorial policies or a targeted approach on key quality items, may promote improvements in reporting. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Stewart R. Sutherland LANGUAGE AND INTERPRETATION IN CRIME AND PUNISHMENT OF some novels it is possible to argue with justification that the problems of interpretation and understanding begin on the first page. Of Dostoyevsky's Crime and Punishment it is possible to contend that the problems of interpretation and understanding begin on the title page. The terms "crime" and "punishment" are overtly moral. The novel is read in the (...) context of a title which exhibits its values where they may be seen by all. What significance must we attach to the choice of such a title? It is possible that the title gives to us a characterization of the content of the novel which, retrospectively, we can only regard as either self-consciously ironical, or perhaps pathetically so, but how are we to decide whether this is more than a possibility? Having raised this question, I propose to set it aside in the hope of returning to it equipped with the experience derived from a number of literary and philosophical digressions. The literary and conceptual style of critical comment upon a novel often betrays much that is definitive of the response being elucidated. If one compares and contrasts Philip Rahv's essay on Crime and Punishment with the appropriate chapter of Mochulsky's Dostoevsky,2 the implication of this general claim may be clarified. My intention here is to use largely ostensive means to suggest the radically different accounts of the novel given to us by these two writers. That the conclusions are different is hardly in need of statement. What is worth examining is the character of the language and of the arguments used to substantiate those conclusions. The point of my discussion will rest not upon assessing the accuracy or legitimacy of particular judgments, but rather upon delineating the general contours of the intellectual contexts in which these judgments are offered. 223 224Philosophy and Literature Rahv's focus is on the character or psyche of Raskolnikov. The novel is seen largely in the form of a psychological study of the mind of the murderer. He reminds us that a central problem for Raskolnikov, for the reader, and for Dostoyevsky himself, is the identification of Raskolnikov's motive—not that there is an absence of motives, indeed quite the reverse: "He is soon lost in the maze of his own motivation" (p. 20). His mind spins incessantly upon an axis the nature of which is nowhere made unambiguously apparent. Nor, it seems, can we replace our search for a motive, or the sufficient reason for action, by identifying a supreme assertion of will: again, on the contrary, we are told, "Dostoyevsky is the first novelist to have fully accepted and dramatized the principle of uncertainty or indeterminacy in the presentation of character" (p. 21). Despite that, however, the success of the novel rests upon Dostoyevsky's skills in allying the insight "... that human consciousness is inexhaustible and incalculable" (p. 19), to "his capacity to combine [seeming contradictions] in a single brain and a single psyche, while staving off the danger of incoherence at one end and of the specious reconciliation at the other..." (p. 38). The mood ofRahv's treatment of the novel is dominated in this way by the language of (largely popularized) psychology—"pathological depression," "nameless guilt-feelings," "wishful fantasy"—and not surprisingly, he sees his own preoccupations as mirroring those of Dostoyevsky: "What Dostoyevsky has done in revising Raskolnikov's justification is to convert into a theory of human nature what is in Hegel not a psychological theory at all but a theory of men as subjects and objects of history" (p. 34). Mochulsky, on the other hand, breathes a very different atmosphere. From the outset he talks of "the spiritual existence of Dostoyevsky's heroes," and he says of a man who wills a murder or one who "betrays himself to the powers of dark necessity" (pp. 302-303), "The murderer has stepped beyond something more than the moral law: the very basis ofthe spiritual worlditself" (p. 303). "The whole tragedy of man-godhood," he tells us, "is expressed in these few words: 'It seems to me,' Raskolnikov says, 'truly great people experience an immense... (shrink)

Previous findings indicate that negative arousal enhances bottom-up attention biases favouring perceptual salient stimuli over less salient stimuli. The current study tests whether those effects were driven by emotional arousal or by negative valence by comparing how well participants could identify visually presented letters after hearing either a negative arousing, positive arousing or neutral sound. On each trial, some letters were presented in a high contrast font and some in a low contrast font, creating a set of targets that differed (...) in perceptual salience. Sounds rated as more emotionally arousing led to more identification of highly salient letters but not of less salient letters, whereas sounds’ valence ratings did not impact salience biases. Thus, arousal, rather than valence, is a key factor enhancing visual processing of perceptually salient targets. (shrink)

The title of this paper proclaims its central interest—the relationship which holds between the concept of integrity and the concept of the identity of the self, or, for short, self-identity. Unreflective speech often suggests a close relationship between the two, but in the latter half of this century, notwithstanding one or two notable exceptions, they have been discussed with minimum cross-reference as if they belonged to two rather different philosophical menus which tended not to be available at the same restaurant (...) on the same night. My intention is to argue that our account of the one carried implications for the other and that this relationship is reflexive. My argument will proceed by stating and criticizing a common account of the relationship between each of these concepts which tends to offer mutual support for the implied account of each. Thereafter an alternative account will be outlined. (shrink)

My argument will be that our understanding of human beings, which is what I take the Christian doctrine of man to be concerned with, will benefit considerably from an examination of two different but related clusters of human attitudes which can be found respectively under the headings ‘optimism’ and ‘pessimism’. There are many pitfalls in the way of such an enterprise, and occasionally some prejudices to be overcome. For example L. E. Loemker in the relevant articles in the Encyclopedia of (...)

This book discusses five philosophers and writers, Hume, Kierkegaar, Camus, Simone Weil and Dostoevsky, who represents different strands of our cultural inheritance which are all theologically and religiously alive today. What they have in common is willingness to explore the borderlands between belief and unbelief and to review their own position in the light of what those coming from the opposite direction may have to teach them. What they each reject is the sort of caricature which assumes that belief an (...) unbelief and to review their own position in the light of what those coming from the opposite direction may have to teach them. What they each reject is the sort of caricature which assumes that belief and unbelief are two homogeneous wholes which have nothing to say to each other and no ground for common discussion other that that of agnosticism. Equally, however, they disdain the implications that the only possibility of dialogue is a marshmallow middle ground where the only rule is that you avoid saying what you really think. Theologians and believers have often stood back from exploration on this middle ground. Encounters with secular philosophies or systems of belief are risky and dangerous. On the other hand, a theology which avoids such encounters is a much impoverished theology. Professor Sutherland's discussion considers the nature and extent of the risk, and the title of his book indicates where the believers who live close to the boundaries often share more with neighbourly unbelievers than they do with fellow believers who view the pastures of unbelief as far distant and dangerou lands from which they will for ever remain separated.

1 Evidence-based policy requires researchers to provide the answers to ecological questions that are of interest to policy makers. To find out what those questions are in the UK, representatives from 28 organizations involved in policy, together with scientists from 10 academic institutions, were asked to generate a list of questions from their organizations. 2 During a 2-day workshop the initial list of 1003 questions generated from consulting at least 654 policy makers and academics was used as a basis for (...) generating a short list of 100 questions of significant policy relevance. Short-listing was decided on the basis of the preferences of the representatives from the policy-led organizations. 3 The areas covered included most major issues of environmental concern in the UK, including agriculture, marine fisheries, climate change, ecosystem function and land management. 4 The most striking outcome was the preference for general questions rather than narrow ones. The reason is that policy is driven by broad issues rather than specific ones. In contrast, scientists are frequently best equipped to answer specific questions. This means that it may be necessary to extract the underpinning specific question before researchers can proceed. 5 Synthesis and applications. Greater communication between policy makers and scientists is required in order to ensure that applied ecologists are dealing with issues in a way that can feed into policy. It is particularly important that applied ecologists emphasize the generic value of their work wherever possible. (shrink)

In this paper I propose to examine three different accounts of what it means to talk of God as eternal. Probably the most generally understood sense in which God is believed to be eternal is that of timelessness, as expounded for example by Boethius and Aquinas. An alternative view on the matter is to be found in Nelson Pike's God and Timelessness and in Richard Swinburne's The Coherence of Theism. Swinburne argues explicitly, and Pike implicitly, that talk of the eternity (...) of God is better understood as talk of the everlastingness (or, as others prefer it, the sempiternity) of God. My argument is that difficulties arise in the published presentations of both of these accounts of the eternity of God. The final section of the paper will outline a third possible account of this belief which, if intelligible, will preserve some at least of the content of what the belief is often taken to be, but which will certainly exclude many of the claims regarded as true by Aquinas, as well as most of those whose mutual coherence is defended by Swinburne.

In the last ten years or so there has been some lively discussion of the questions of immortality and resurrection. Within the Christian tradition there has been debate at theological and exegetical level over the relative merits of belief in the immortality of the soul, and belief in the resurrection of the dead as an account of life after death. Further to this, however, there has been the suggestion that there may be good philosophical reasons for preferring the latter to (...) the former. It is just this contention which I propose to discuss. (shrink)
