Eric Lewis - God and Reason in the Middle Ages - Journal of the History of Philosophy 40:3 Journal of the History of Philosophy 40.3 393-394 Book Review God and Reason in the Middle Ages Edward Grant. God and Reason in the Middle Ages. New York: Cambridge University Press, 2001. Pp. ix + 397. Cloth, $64.95. Paper, $22.95. History has not been kind to the vast era we call the "Middle Ages." The name designates an intellectual hiatus between (...) the philosophical and technical genius of ancient Greece and Rome and the "rebirth" of knowledge in the Renaissance. Edward Grant wants this to change. He suggests that we consider the period following the establishment of scholasticism until the sixteenth century the pinnacle of an "Age of Reason." In this vein, Grant's latest book is pure apologetics for the Middle Ages. Grant.. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 62.4 (2001) 651-664 [Access article in PDF] Walter Charleton and Early Modern Eclecticism Eric Lewis The publication of Michael Albrecht's Eklektik (1994) revived a small amount of scholarly interest in an early modern "movement" with a lineage that can be traced back to Clement of Alexandria, who described a method of constructing a philosophical system by selecting among different philosophical sects. (...) 1 Not surprisingly, the reception of Albrecht's work demonstrated the complexities associated with identifying the "movement" and categorizing those who labeled themselves "eclectic" philosophers; that is, those who seemed to expound a system of philosophy assimilated from ancient and modern sources. The difficulties involved with defining "eclecticism" and applying the term to early modern natural science is further complicated by the tendency for "eclectics" to categorize their contemporaries in ways that are counterintuitive to our modern sensibilities. 2 Nevertheless, the proponents of this patchwork style of natural science are interesting precisely because they give us a glimpse into their interpretation of the state of philosophy and its relation to history during a time when the authority of The Philosopher was falling under ever increasing scrutiny.The recent literature on philosophic eclecticism largely ignored the English context where rising sentiment against sectarianism influenced the formation of the Royal Society. 3 The perceived chaos of a nation divided and redivided by the multiplication of religious associations produced a plethora of proposals for the restoration and maintenance of intellectual and social order. In particular the problems of religious and political order motivated certain members of the [End Page 651] "Newcastle Circle" (largely Royalists) to construct philosophical methodologies at least congruent with their ideological commitments to social stability. Thomas Hobbes, Margaret Cavendish, and her close friend the physician Walter Charleton each offered his and her own style of natural science. 4 Both Hobbes and the Duchess of Newcastle were excluded from participating in the community of natural philosophers formed in 1660; yet Charleton became a founding member of the Royal Society that year. Despite relative neglect, Charleton's importance to understanding the development of modern natural science in England should not be overlooked; and particularly his prescribed method of doing natural philosophy needs more attention. 5 Like the radically different methods developed by Margaret Cavendish and Thomas Hobbes, Charleton's eclecticism should be viewed as an exhaustive effort to prescribe a remedy to the perceived threat of rampant sectarianism. 6 Unlike Hobbes and Cavendish, however, Charleton saw authoritarianism and dogmatism as the greatest challenge to order, and found the solution to that challenge in mitigated skepticism and a style of philosophy that did not make an epistemic differentiation between the novel philosophies of his day and those of the ancients.Despite being a prolific writer, having a considerable reputation as a physician and placing himself in the center of the English community of natural scientists, Walter Charleton has been mostly ignored by modern scholars. In part this lack of attention can be attributed to the common view that he never developed a comprehensive philosophy nor maintained consistent metaphysical commitments. References to him claim that he was an "intellectual barometer of the age," 7 and his work has been described as "important as a case study in the reception of a mechanical philosophy." 8 His name is virtually absent from discussions concerning scientific methodology, though he is often described as a Renaissance [End Page 652] alchemical philosopher who fell under the influence of mechanistic atomism and the experimental agenda of a fledgling society of natural philosophers. Most accounts simply portray Charleton as a converted follower of the novel philosophy rather than as a novel thinker.The failure to see Charleton as more than a converted empiricist and mechanist likely results from the opinion that eclecticism does not constitute a philosophical method as much as it constitutes the last refuge for scholars during periods of intellectual crisis. The article on eclecticism in Encyclopedia Britannica (fourteenth edition) states: Eclecticism always tends to spring up after a period of vigorous constructive speculation, especially in the later stages of a controversy between...

The history of ancient chemistry has been virtually ignored. I examine the foundations of the chemical theories of the Peripatetics and Stoics, in an attempt to glean the motivations for their chemical theories, and how these theories relate to their greater natural philosophies. This involves a detailed examination of ancient theories of mixture. I attempt to relate Aristotle's theory of mixture to his theories of substantial change, the elements and matter. This entails a rejection of the notion of prime matter, (...) and a reevaluation of the status of the contrarieties. I also look at the understudied fourth book of the Meteorologica, which sheds new light on Aristotle's theory of matter. I then turn to Alexander of Aphrodisias, and his development of Aristotle's theory. Next I consider the Stoic theory of body, and how doxographers have misinterpreted this theory. While offering a radically new interpretation of the Stoic theory of mixture, much of Stoic natural philosophy is reconstructed, including their theory of categories and qualities. In the end a Stoic theory free from obvious paradox is presented. (shrink)

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

The editors of the JRE solicited short essays on the COVID‐19 pandemic from a group of scholars of religious ethics that reflected on how the field might help them make sense of the complex religious, cultural, ethical, and political implications of the pandemic, and on how the pandemic might shape the future of religious ethics.

Günther recently suggested a 'new‘ conditional. This conditional is not new, as already remarked by Wansing and Omori. It is just David Lewis‘ forgotten alternative 'doctored‘ conditional and part of a larger class termed neutral conditionals. In this paper, I answer some questions raised by Wansing and Omori, concerning the motivation, the logic, the connexive flavor and contra-classicality of such neutralized conditionals. The main message being: Neutralizing a vacuist conditional avoids (some) paradoxes of strict implication, changes the logic essentially (...) only by Aristotle‘s Thesis, makes strong connexivity impossible, and remains in the realm of non-contra-classical logics.

In his original semantics for counterfactuals, David Lewis presupposed that the ordering of worlds relevant to the evaluation of a counterfactual admitted no incomparability between worlds. He later came to abandon this assumption. But the approach to incomparability he endorsed makes counterintuitive predictions about a class of examples circumscribed in this paper. The same underlying problem is present in the theories of modals and conditionals developed by Bas van Fraassen, Frank Veltman, and Angelika Kratzer. I show how to reformulate (...) all these theories in terms of lower bounds on partial preorders, conceived of as maximal antichains, and I show that treating lower bounds as cutsets does strictly better at capturing our intuitions about the semantics of modals, counterfactuals, and deontic conditionals. (shrink)

This paper presents and discusses a range of counterexamples to the common view that quantifiers cannot take scope over epistemic modals. Some of the counterexamples raise problems for ‘force modifier’ theories of epistemic modals. Some of the counterexamples raise problems for Robert Stalnaker’s theory of counterfactuals, according to which a special kind of epistemic modal must be able to scope over a whole counterfactual. Finally, some of the counterexamples suggest that David Lewis must countenance ‘would’ counterfactuals in which a (...) covert ‘would’ scopes over the whole consequent of the counterfactual, including an overt ‘might.’. (shrink)

The variably strict analysis of conditionals does not only largely dominate the philosophical literature, since its invention by Stalnaker and Lewis, it also found its way into linguistics and psychology. Yet, the shortcomings of Lewis–Stalnaker’s account initiated a plethora of modifications, such as non-vacuist conditionals, presuppositional indicatives, perfect conditionals, or other conditional constructions, for example: reason relations, difference-making conditionals, counterfactual dependency, or probabilistic relevance. Many of these new connectives can be treated as strengthened or weakened conditionals. They are (...) definable conditionals. This article develops a technique to infer the logic for such definable conditionals from the known logic of the underlying defining conditional. The technique is applied to central examples. The results show that a large part of the zoo of conditionals arises from a basic conditional—a constant nucleus of the different contextual and conceptual variations of variably strict conditionals. (shrink)

Standard conditionals $\varphi > \psi$, by which I roughly mean variably strict conditionals à la Stalnaker and Lewis, are trivially true for impossible antecedents. This article investigates three modifications in a doxastic setting. For the neutral conditional, all impossible-antecedent conditionals are false, for the doxastic conditional they are only true if the consequent is absolutely necessary, and for the metaphysical conditional only if the consequent is ‘model-implied’ by the antecedent. I motivate these conditionals logically, and also doxastically by properties (...) of conditional belief and belief revision. For this I show that the Lewisian hierarchy of conditional logics can be reproduced within ranking semantics, provided we slightly stretch the notion of a ranking function. Given this, acceptance of a conditional can be interpreted as a conditional belief. The epistemic and the neutral conditional deviate from Lewis’ weakest system $V$, in that ID or even CN are dropped, and new axioms appear. The logic of the metaphysical conditional is completely axiomatised by $V$ to which we add the known Kripke axioms T5 for the outer modality. Related completeness results for variations of the ranking semantics are obtained as corollaries. (shrink)

According to Stalnaker’s Thesis, the probability of a conditional is the conditional probability. Under some mild conditions, the thesis trivialises probabilities and conditionals, as initially shown by David Lewis. This article asks the following question: does still lead to triviality, if the probability function in is replaced by a probability-like function? The article considers plausibility functions, in the sense of Friedman and Halpern, which additionally mimic probabilistic additivity and conditionalisation. These quasi probabilities comprise Friedman–Halpern’s conditional plausibility spaces, as well (...) as other known representations of conditional doxastic states. The paper proves Lewis’ triviality for quasi probabilities and discusses how this has implications for three other prominent strategies to avoid Lewis’ triviality: Adams’ thesis, where the probability function on the left in is replaced by a probability-like function, abandoning conditionalisation, where probability conditionalisation on the right in is replaced by another propositional update procedure and the approximation thesis, where equality in is replaced by approximation. The paper also shows that Lewis’ triviality result is really about ‘additiveness’ and ‘conditionality’. (shrink)

I develop an account of counterfactual conditionals using “causal models”, and argue that this account is preferable to the currently standard account in terms of “similarity of possible worlds” due to David Lewis and Robert Stalnaker. I diagnose the attraction of counterfactual theories of causation, and argue that it is illusory.

For a period of several years the philosopher of science Hasok Chang has promoted various inter-related views including pluralism, pragmatism, and an associated view of natural kinds. He has also argued for what he calls the persistence of everyday terms in the scientific view. Chang claims that terms like phlogiston were never truly abandoned but became transformed into different concepts that remain useful. On the other hand, Chang argues that some scientific terms such as acidity have suffered a form of (...) “rupture”, especially in the case of the modern Lewis definition of acids. Chang also complains that the degree of acidity of a Lewis acid cannot be measured using a pH meter and seems to regard this as a serious problem. The present paper examines some of these views, especially what Chang claims to be a rupture in the definition of acidity. It is suggested that there has been no such rupture but a genuine generalization, on moving from the Brønsted-Lowry theory to the Lewis theory of acidity. It will be shown how the quantification and measurement of Lewis acidity can easily be realized through the use of equilibrium theory and the use of stability constants. (shrink)

In this paper c i lewis's theory of practical reason is discussed. the purpose is to explicate the role which value experience plays in the thinking of a rational agent who is attempting to determine imperatives of action. lewis, who vehemently opposed noncognitivism in ethics, believed that the objectivity of ethics could be shown to be the result of the logical demands of consistency upon the deliberative consciousness of an active self-determining agent. rightness, for lewis, was not (...) primarily a moral concept but rather a logical concept to be exercised in the critique of any deliberate activity; ethics thus rests on very general features of agent rationality.

In a survey of his views in the philosophy of mind, David Lewis criticizes much recent work in the field by attacking an imaginary opponent, Strawman. His case against Strawman focuses on four central theses which Lewis takes to be widely accepted among contemporary philosophers of mind. These theses concern (1) the language of thought hypothesis and its relation to folk psychology, (2) narrow content, (3) de se content, and (4) rationality. We respond to Lewis, arguing that (...) he underestimates Strawman’s theoretical resources in a variety of important ways. (shrink)

A god is a cosmic designer-creator. Atheism says the number of gods is 0. But it is hard to defeat the minimal thesis that some possible universe is actualized by some possible god. Monotheists say the number of gods is 1. Yet no degree of perfection can be coherently assigned to any unique god. Lewis says the number of gods is at least the second beth number. Yet polytheists cannot defend an arbitrary plural number of gods. An alternative is (...) that, for every ordinal, there is a god whose perfection is proportional to it. The n -th god actualizes the best universe(s) in the n -th level of an axiological hierarchy of possible universes. Despite its unorthodoxy, ordinal polytheism has many metaphysically attractive features and merits more serious study. (shrink)

I argue that recent empirical investigations reveal new problems and new evidence that should compel advocates of causal functionalism (of the sort defended by David Armstrong and David Lewis) to reconsider the feasibility of their account of mind.

I argue against counterfactual theories of causation , develop a pragmatic version of the Covering Law view, and offer a causal theory of counterfactuals. ;The initial idea of CTCs is that event a causes event b if b would not have occurred, if a had not occurred. David Lewis proposes this view as a solution to problems of "effects" and "epiphenomena". I argue that CTCs cannot solve these problems. Covering Law theories can, but only by rejecting traditional Humean accounts (...) of laws. ;Following Nancy Cartwright , I argue that there is no a priori route from probabilistic association to causal relevance, and that distinguishing causal relevance from mere association requires further causal knowledge. Some recent literature on causal modelling is also examined. ;Much causal knowledge concerns rough, approximate ceteris paribus laws and generalizations. I examine these and argue that they involve important pragmatic components. ;Many aspects of intuitive causal judgment and reasoning are explained by ceteris paribus causes. For example, many causes are preventable, and only ceteris paribus causes could be prevented. Ceteris paribus causes are capacities, which make similar contributions to different circumstances, and interact with each other . The pragmatic features of ceteris paribus laws hold equally of ceteris paribus causes. ;Singular and generic causes are unified by appeal to the a posteriori impossibility of "action at a distance". The locality of causal relations requires that causes act by continuous intervening processes. Singular causes and effects are instances of generic causal process types. ;Numerous cases of unclear and conflicting intuitions about causes and effects are explained by contextual factors . ;I explain away the attraction of CTCs by offering a causal account of counterfactuals. It is natural to express causal facts using counterfactuals because the truth conditions of counterfactuals are direct consequences of causal facts. (shrink)

We show that Lewis’s modal realism, and his serviceability-based argument for it, cohere with his epistemological contextualism. Modal realism explains why serviceability-based reasoning in metaphysics might be reliable, while Lewis’s contextualism explains why Lewis can properly ignore the possibility that serviceability isn’t reliable, at least when doing metaphysics. This is because Lewis’s contextualism includes a commitment to a kind of pragmatic encroachment, so that whether a subject knows can depend on how much is at stake with (...) respect to whether the belief is true or false. Accordingly, we suggest that Lewis can count as knowing that serviceability is a reliable guide to truth in metaphysics, since the stakes are generally low there, and so can be justified in believing that modal realism is true based on its serviceability.

This paper studies proof systems for the logics of super-strict implication \(\textsf{ST2}\) – \(\textsf{ST5}\), which correspond to C.I. Lewis’ systems \(\textsf{S2}\) – \(\textsf{S5}\) freed of paradoxes of strict implication. First, Hilbert-style axiomatic systems are introduced and shown to be sound and complete by simulating \(\textsf{STn}\) in \(\textsf{Sn}\) and backsimulating \(\textsf{Sn}\) in \(\textsf{STn}\), respectively (for \({\textsf{n}} =2, \ldots, 5\) ). Next, \(\textsf{G3}\) -style labelled sequent calculi are investigated. It is shown that these calculi have the good structural properties that are (...) distinctive of \(\textsf{G3}\) -style calculi, that they are sound and complete, and it is shown that the proof search for \(\mathsf {G3.ST2}\) is terminating and therefore the logic is decidable.

Cost-benefit analysis is a widely used governmental evaluation tool, though academics remain skeptical. This volume gathers prominent contributors from law, economics, and philosophy for discussion of cost-benefit analysis, specifically its moral foundations, applications and limitations. This new scholarly debate includes not only economists, but also contributors from philosophy, cognitive psychology, legal studies, and public policy who can further illuminate the justification and moral implications of this method and specify alternative measures. These articles originally appeared in the Journal of Legal Studies. (...) Contributors: - Matthew D. Adler - Gary S. Becker - John Broome - Robert H. Frank - Robert W. Hahn - Lewis A.

We aren’t particularly sympathetic to modal realism (MR). Still, it isn’t clear to us that David Lewis argues for it in the wrong way. “The hypothesis is serviceable,” he says, “and that is a reason to think that it is true” (1986, p. 3). Let’s grant him the first claim: MR is serviceable, which is to say that it allows us “to reduce the diversity of notions we must accept as primitive, and thereby to improve the unity and economy (...) of the theory that is our professional concern – total theory, the whole of what we take to be true” (1986, p. 4). Our interest here is in the second claim, the thesis to the effect that a hypothesis’s being serviceable can provide reason to believe it. A number of philosophers maintain that this latter is false; others insist that it’s of no help to Lewis. So on one basis or the other, they conclude that Lewis’ argument for MR doesn’t get off the ground.1 We disagree. Our aim here is to show that there isn’t a cogent objection to Lewis’ use of serviceability that doesn’t rely a premise that he is justified in rejecting. (shrink)

Prof. Ruth Barcan Marcus created quantified modal logic in 1946. She extended the Lewis calculus S2 to cover quantification. Quantified modal logic became an essential tool for the rigorous study of natural language in the hands of R. Montague in the late sixties. Some complex phenomena cannot be properly handled at the level of sentences. Recent researches in formal semantics have concentrated on discourse and led to a rich amount of results. Logical theories introduced for the logical study of (...) programs play an important role in these developments. We shall present a detailed account of the connection between dynamic logic and “static” logic. The core of the paper will be the translation of dynamic logic into S5. Developping an insight due to Prof. J. van Eijck, We shall offer a simplified version of the latter translation. The paper also relates to P. Gärdenfors' Knowledge in Flux. (shrink)

In this paper, we investigate the semantics and logic of choice-driven counterfactuals, that is, of counterfactuals whose evaluation relies on auxiliary premises about how agents are expected to act, i.e., about their default choice behavior. To do this, we merge one of the most prominent logics of agency in the philosophical literature, namely stit logic, with the well-known logic of counterfactuals due to Stalnaker and Lewis. A key component of our semantics for counterfactuals is to distinguish between deviant and (...) non-deviant actions at a moment, where an action available to an agent at a moment is deviant when its performance does not agree with the agent’s default choice behavior at that moment. After developing and axiomatizing a stit logic with action types, instants, and deviant actions, we study the philosophical implications and logical properties of two candidate semantics for choice-driven counterfactuals, one called rewind models inspired by Lewis, 455–476 1979) and the other called independence models motivated by well-known counterexamples to Lewis’s proposal Slote, 3–27 1978). In the last part of the paper we consider how to evaluate choice-driven counterfactuals at moments arrived at by some agents performing a deviant action. (shrink)

The lead-off essay by Kenneth Minogue is an Oakeshottian reflection on the extent to which modern people have become passive spectators of action, detached from traditional loyalties and modes of identity and thus a kind of new Epicurean, shorn of the genuinely contemplative character of the originals. Eric Ormsby follows this with a judicious appraisal of the possibilities and perils for culture associated with the advent of the new information technology. Anthony Daniels provides a similarly sober account of the (...) many consequences and dilemmas of medical technology for the noble Hippocratic art. David Pryce-Jones’s essay recounts the antipolitical utopianism of the totalitarian ideologies that shadowed most of the twentieth century and worries about the potentially destructive utopian tendencies in the contemporary project of European integration. Keith Windschuttle surveys the range of ideologies currently deployed in the academy, most of which derive from vulgarizations of Nietzsche. Edward Said’s influential body of work comes in for particular scrutiny here. Mark Steyn contributes a discussion of the now all-too-familiar self-hatred of Western intellectuals with the blunt precision and wit so characteristic of his splendid newspaper columns. Martin Greenberg’s essay on Burke manages to educe in brief compass the understanding of freedom that is the animating heart of that exemplary statesman’s thought and practice. Diana Schaub makes a case for the importance of political philosophy to the practice of modern politics centered on the statesmanship of Lincoln. Robert Bork’s chapter on the “adversary judiciary” limns the extent to which judges have gone from being the guarantors of the rule of law to the most effective antagonists of traditional institutions and values. Finally, Roger Kimball fittingly recalls the original Ciceronian understanding of culture as the development of the mind analogous to the cultivation of the earth, and connects it with the celebrated program of criticism proposed by Matthew Arnold.
