This paper analyzes a key theoretical assumption of the "classical twin method": the so-called "equal environment assumption" . The purpose of the discussion is to determine whether this assumption, which states that identical and fraternal twins experience similar environments, is valid. Following a brief discussion of the origins of the twin method and the views of its main critics, the arguments of its principal contemporary defenders are examined in detail. This discussion is followed by a critique of several studies (...) which have been cited as evidence in support of the equal environment assumption. It is concluded that the equal environment assumption does not stand up to critical examination, thereby calling into question the claim that the twin method measures genetic effects on human behavior and personality differences.

This paper deals with the rationalist assumptions behind researches of artificial intelligence (AI) on the basis of Hubert Dreyfus’s critique. Dreyfus is a leading American philosopher known for his rigorous critique on the underlying assumptions of the field of artificial intelligence. Artificial intelligence specialists, especially those whose view is commonly dubbed as “classical AI,” assume that creating a thinking machine like the human brain is not a too far away project because they believe that human intelligence works (...) on the basis of formalized rules of logic. In contradistinction to classical AI specialists, Dreyfus contends that it is impossible to create intelligent computer programs analogous to the human brain because the workings of human intelligence is entirely different from that of computing machines. For Dreyfus, the human mind functions intuitively and not formally. Following Dreyfus, this paper aims to pinpointing the major flaws classical AI suffers from. The author of this paper believes that pinpointing these flaws would inform inquiries on and about artificial intelligence. Over and beyond this, this paper contributes something indisputably original. It strongly argues that classical AI research programs have, though inadvertently, falsified an entire epistemological enterprise of the rationalists not in theory as philosophers do but in practice. When AI workers were trying hard in order to produce a machine that can think like human minds, they have in a way been testing—and testing it up to the last point—the rationalist assumption that the workings of the human mind depend on logical rules. Result: No computers actually function like the human mind. Reason: the human mind does not depend on the formal or logical rules ascribed to computers. Thus, symbolic AI research has falsified the rationalist assumption that ‘the human mind reaches certainty by functioning formally’ by virtue of its failure to create a thinking machine. (shrink)

Quantitative genetics (QG) analyses variation in traits of humans, other animals, or plants in ways that take account of the genealogical relatedness of the individuals whose traits are observed. “Classical” QG, where the analysis of variation does not involve data on measurable genetic or environmental entities or factors, is reformulated in this article using models that are free of hypothetical, idealized versions of such factors, while still allowing for defined degrees of relatedness among kinds of individuals or “varieties.” The (...) gene - free formulation encompasses situations encountered in human QG as well as in agricultural QG. This formulation is used to describe three standard assumptions involved in classical QG and provide plausible alternatives. Several concerns about the partitioning of trait variation into components and its interpretation, most of which have a long history of debate, are discussed in light of the gene-free formulation and alternative assumptions. That discussion is at a theoretical level, not dependent on empirical data in any particular situation. Additional lines of work to put the gene-free formulation and alternative assumptions into practice and to assess their empirical consequences are noted, but lie beyond the scope of this article. The three standard QG assumptions examined are: (1) partitioning of trait variation into components requires models of hypothetical, idealized genes with simple Mendelian inheritance and direct contributions to the trait; (2) all other things being equal, similarity in traits for relatives is proportional to the fraction shared by the relatives of all the genes that vary in the population (e.g., fraternal or dizygotic twins share half of the variable genes that identical or monozygotic twins share); (3) in analyses of human data, genotype-environment interaction variance (in the classical QG sense) can be discounted. The concerns about the partitioning of trait variation discussed include: the distinction between traits and underlying measurable factors; the possible heterogeneity in factors underlying the development of a trait; the kinds of data needed to estimate key empirical parameters; and interpretations based on contributions of hypothetical genes; as well as, in human studies, the labeling of residual variance as a non-shared environmental effect; and the importance of estimating interaction variance.

The biological sciences provide ample opportunity and motivation for feminist interventions. These sciences are seen by many as an authority on human nature and are highly relevant to many issues of social justice and public policy. Feminist philosophy of biology focuses on the ethical and epistemic adequacy and responsibility of biological claims. This work is critical in the sense of identifying epistemically and ethically irresponsible knowledge claims, research practices, and dissemination of biological research regarding sex/gender, including ways that sex/gender interacts (...) with other social categories. In this chapter we describe classic themes in feminist philosophy of biology, with particular regard to research practices and metaphysical assumptions. We then go on to argue that these classic themes remain salient in contemporary neuroscientific investigations of human emotion and in feminist research on the evolution of human behavior. (shrink)

Proof-theoretic semantics is an inferentialist theory of meaning, usually developed in a multiple-assumption and single-conclusion framework. In that framework, this theory seems unable to justify classical logic, so some authors have proposed a multiple-conclusion reformulation to accomplish this goal. In the first part of this paper, the debate originated by this proposal is briefly exposed and used to defend the diverging opinion that proof-theoretic semantics should always endorse a single-assumption and single-conclusion framework. In order to adopt this approach some (...) of its _criteria_ of validity, especially separability, need to be weakened. This choice is evaluated and defended. The main argument in this direction is based on the circular dependences of meaning between multiple assumptions and conjunctions, and between multiple conclusions and disjunctions. In the second part of this paper, some systems that suit the new requirements are proposed for both intuitionistic and classical logic. A proof that they are valid, according to the weakened _criteria_, is sketched. (shrink)

The relationship between classical and quantum theory is of central importance to the philosophy of physics, and any interpretation of quantum mechanics has to clarify it. Our discussion of this relationship is partly historical and conceptual, but mostly technical and mathematically rigorous, including over 500 references. For example, we sketch how certain intuitive ideas of the founders of quantum theory have fared in the light of current mathematical knowledge. One such idea that has certainly stood the test of time (...) is Heisenberg's `quantum-theoretical Umdeutung (reinterpretation) of classical observables', which lies at the basis of quantization theory. Similarly, Bohr's correspondence principle (in somewhat revised form) and Schroedinger's wave packets (or coherent states) continue to be of great importance in understanding classical behaviour from quantum mechanics. On the other hand, no consensus has been reached on the Copenhagen Interpretation, but in view of the parodies of it one typically finds in the literature we describe it in detail. On the assumption that quantum mechanics is universal and complete, we discuss three ways in which classical physics has so far been believed to emerge from quantum physics, namely in the limit h -> 0 of small Planck's constant (in a finite system), in the limit N goes to infinity of a large system with $N$ degrees of freedom (at fixed h), and through decoherence and consistent histories. The first limit is closely related to modern quantization theory and microlocal analysis, whereas the second involves methods of C*-algebras and the concepts of superselection sectors and macroscopic observables. In these limits, the classical world does not emerge as a sharply defined objective reality, but rather as an approximate appearance relative to certain ``classical" states and observables. Decoherence subsequently clarifies the role of such states, in that they are ``einselected", i.e. robust against coupling to the environment. Furthermore, the nature of classical observables is elucidated by the fact that they typically define (approximately) consistent sets of histories. This combination of ideas and techniques does not quite resolve the measurement problem, but it does make the point that classicality results from the elimination of certain states and observables from quantum theory. Thus the classical world is not created by observation (as Heisenberg once claimed), but rather by the lack of it. (shrink)

Hilbert’s choice operators τ and ε, when added to intuitionistic logic, strengthen it. In the presence of certain extensionality axioms they produce classical logic, while in the presence of weaker decidability conditions for terms they produce various superintuitionistic intermediate logics. In this thesis, I argue that there are important philosophical lessons to be learned from these results. To make the case, I begin with a historical discussion situating the development of Hilbert’s operators in relation to his evolving program in (...) the foundations of mathematics and in relation to philosophical motivations leading to the development of intuitionistic logic. This sets the stage for a brief description of the relevant part of Dummett’s program to recast debates in metaphysics, and in particular disputes about realism and anti-realism, as closely intertwined with issues in philosophical logic, with the acceptance of classical logic for a domain reflecting a commitment to realism for that domain. Then I review extant results about what is provable and what is not when one adds epsilon to intuitionistic logic, largely due to Bell and DeVidi, and I give several new proofs of intermediate logics from intuitionistic logic+ε without identity. With all this in hand, I turn to a discussion of the philosophical significance of choice operators. Among the conclusions I defend are that these results provide a finer-grained basis for Dummett’s contention that commitment to classically valid but intuitionistically invalid principles reflect metaphysical commitments by showing those principles to be derivable from certain existence assumptions; that Dummett’s framework is improved by these results as they show that questions of realism and anti-realism are not an “all or nothing” matter, but that there are plausibly metaphysical stances between the poles of anti-realism and realism, because different sorts of ontological assumptions yield intermediate rather than classical logic; and that these intermediate positions between classical and intuitionistic logic link up in interesting ways with our intuitions about issues of objectivity and reality, and do so usefully by linking to questions around intriguing everyday concepts such as “is smart,” which I suggest involve a number of distinct dimensions which might themselves be objective, but because of their multivalent structure are themselves intermediate between being objective and not. Finally, I discuss the implications of these results for ongoing debates about the status of arbitrary and ideal objects in the foundations of logic, showing among other things that much of the discussion is flawed because it does not recognize the degree to which the claims being made depend on the presumption that one is working with a very strong logic.

This paper evaluates the economic assumptions of economic theory via an examination of the capitalist transformation of creditor–debtor relations in the 18th century. This transformation enabled masses of people to obtain credit without moral opprobrium or social subordination. Classical 18th century economics had the ethical concepts to appreciate these facts. Ironically, contemporary economic theory cannot. I trace this fault to its abstract representations of freedom, efficiency, and markets. The virtues of capitalism lie in the concrete social relations and (...) social meanings through which capital and commodities are exchanged. Contrary to laissez faire capitalism, the conditions for sustaining these concrete capitalist formations require limits on freedom of contract and the scope of private property rights. (shrink)

There has been a longstanding and acrimonious debate in the human sciences over the role played by classic texts. Advocates of the classic insist its value is timeless and rests on the intrinsic superiority of its cognitive insights and aesthetic virtues. Critics, by contrast, argue that the respect accorded the classic is spurious because it conceals the ideological assumptions, tensions and discontinuities of tradition. This paper seeks a solution through the account of ‘the classical’ brought by Hans-Georg Gadamer (...) in Truth and Method, which acknowledges a text’s ‘eminence’ as well as its ‘historicity’. Following the introduction, the paper divides into four sections. Section one, notes that the hermeneutic account of tradition describes it as being open to challenge rather than closed and unchangeable, and that the classic, as grounded in tradition, will conserve difficulty as readily as comfortable certainty. Section two focuses on the idea that in the classic we find matter ‘properly portrayed’, while section three notes the importance of ‘application’ for an understanding of classic texts. It is noted that both ‘proper portrayal’ and ‘application’ depend on recognising the role of the fusion of historical horizons in generating classic texts. The final section challenges the criticism that the classic is no more than a reflection of the institutional power wielded by the canon, arguing instead that the classic and the canon are different entities, and conflating them in favour of the latter, misleadingly reduces classic-ness to being no more than an effect of canonicity.

Bohmian mechanics is a realistic interpretation of quantum theory. It shares the same ontology of classical mechanics: particles following continuous trajectories in space through time. For this ontological continuity, it seems to be a good candidate for recovering the classical limit of quantum theory. Indeed, in a Bohmian framework, the issue of the classical limit reduces to showing how classical trajectories can emerge from Bohmian ones, under specific classicality assumptions. In this paper, we shall focus (...) on a technical problem that arises from the dynamics of a Bohmian system in bounded regions; and we suggest that a possible solution is supplied by the action of environmental decoherence. However, we shall show that, in order to implement decoherence in a Bohmian framework, a stronger condition is required rather than the usual one. (shrink)

As an atheistic religious tradition, Buddhism conventionally stands in opposition to Christianity, and any bridge between them is considered to be riddled with contradictory beliefs on God the creator, salvific power and the afterlife. But what if a Buddhist could also be a Classical Theist? Showing how the various contradictions are not as fundamental as commonly thought, Tyler Dalton McNabb and Erik Baldwin challenge existing assumptions and argue that Classical Theism is, in fact, compatible with Buddhism. They (...) draw parallels between the metaphysical doctrines of both traditions, synthesize their ethical and soteriological commitments and demonstrate that the Theist can interpret the Buddhist's religious experiences, specifically those of emptiness, as veridical, without denying any core doctrine of Classical Theism. By establishing that a synthesis of the two traditions is plausible, this book provides a bold, fresh perspective on the philosophy of religion and reinvigorates philosophical debates between Buddhism and Christianity.

Classical realism is enjoying a renaissance in the study of international relations. It is well known that the analytical and normative international-political thought of early 20th-century classical realists is based on assumptions about human nature. Yet current knowledge of these assumptions remains limited. This article therefore revisits and examines the nature and intellectual roots of the human nature assumptions of three truly consequential classical realists. The analysis shows — similar to the causa Hans J. (...) Morgenthau — that the human nature assumptions of George F. Kennan, Walter Lippmann and E. H. Carr are — to varying degrees — Freudian. Unless this hitherto neglected dimension is recognized, an understanding of their international-political thought and of the political philosophy of realism remains incomplete. Two conclusions are presented. First, current criticism of classical realism’s human nature assumptions is unjustified. Second, any (re-) engagement with classical realism must recognize its human nature baggage. Realist international-political theorizing is necessarily human nature-based international-political theorizing. (shrink)

Although pragmatism and phenomenology have both contributed significantly to the genealogy of so-called “4E” – embodied, embedded, enactive and extended – cognition, there is benefit to be had from a systematic comparative study of these roots. As existing 4E cognition literature has tended to emphasise one or the other tradition, issues remain to be addressed concerning their commonalities – and possible incompatibilities. We begin by exploring pragmatism and phenomenology’s shared focus on contesting intellectualism, and its key assumption of mindedness as (...) representation. We then outline distinctive insights from both traditions regarding the nature and role of habits, in order to put forward a habit-based epistemology as an alternative to the Cartesian idea-based epistemology that has dominated modern philosophy. We pay particular attention to the work of classical pragmatist C.S. Peirce, arguing that his semiotics, which analyses sign-use as habit, shows how theorists of embodied cognition can break a certain false dichotomy between embodiment and logical or intellectual structure which has prevented them from fully theorising propositional knowledge. In this way, our work both augments and challenges the Dewey/Merleau-Ponty connection that has been much more extensively explored by the field. (shrink)

According to logical inferentialists, the meanings of logical expressions are fully determined by the rules for their correct use. Two key proof-theoretic requirements on admissible logical rules, harmony and separability, directly stem from this thesis—requirements, however, that standard single-conclusion and assertion-based formalizations of classical logic provably fail to satisfy :1035–1051, 2011). On the plausible assumption that our logical practice is both single-conclusion and assertion-based, it seemingly follows that classical logic, unlike intuitionistic logic, can’t be accounted for in inferentialist (...) terms. In this paper, I challenge orthodoxy and introduce an assertion-based and single-conclusion formalization of classical propositional logic that is both harmonious and separable. In the framework I propose, classicality emerges as a structural feature of the logic. (shrink)

We offer thoughts on Shadmehr and Ahmed's foundational assumption that behavioral intensity (vigor) is proportional to the perceived value of outcomes driving behavior (incentives). The assumption is reasonable considering classical motivational thought and scholarship in related literatures but called into question by an influential contemporary theory of motivation by Brehm. Brehm's theory suggests that the assumption is warranted in some, but not all, performance circumstances. Furthermore, proportionality between vigor and value might be generated through a deliberative goal-setting process rather (...) than through intrinsic neural linkages. (shrink)

Chris Fraser presents a rich and broad-ranging study of the culminating period of classical Chinese philosophy, the third century BC. He offers novel and informative perspectives on Confucianism, Daoism, Mohism, Legalism, and other movements in early Chinese thought while also delving into neglected texts such as the Guanzi, Lu's Annals, and the Zhuangzi 'outer' chapters, restoring them to their prominent place in the history of philosophy. Fraser organizes the history of Chinese thought topically, devoting separate chapters to metaphysics and (...) metaethics, political philosophy, ethics, moral psychology, epistemology, and philosophy of language and logic. Focused specifically on the last century of the Warring States era, arguably the most vibrant, diverse period of philosophical discourse in Chinese history, the discussion covers the shared concerns, rival doctrines, and competing criticisms presented in third-century BC sources. Fraser explicates the distinctive issues, conceptual frameworks, and background assumptions of classical Chinese thought. He aims to introduce the philosophical discourse of early China to a broad audience, including readers with no prior familiarity with the material. At the same time, the thematic treatment and incisive interpretations of individual texts will be of interest to students and specialists in the field. (shrink)

In this paper I defend the classical computational account of reasoning against a range of highly influential objections, sometimes called relevance problems. Such problems are closely associated with the frame problem in artificial intelligence and, to a first approximation, concern the issue of how humans are able to determine which of a range of representations are relevant to the performance of a given cognitive task. Though many critics maintain that the nature and existence of such problems provide grounds for (...) rejecting classical computationalism, I show that this is not so. Some of these putative problems are a cause for concern only on highly implausible assumptions about the extent of our cognitive capacities, whilst others are a cause for concern only on similarly implausible views about the commitments of classical computationalism. Finally, some versions of the relevance problem are not really objections but hard research issues that any satisfactory account of cognition needs to address. I conclude by considering the diagnostic issue of why accounts of cognition in general—and classical computational accounts, in particular—have faired so poorly in addressing such research issues.Keywords: Computationalism; Frame problem; Relevance.

This paper considers possible future legislation that requires the exclusive use of autonomous cars. The author develops and defends a ‘Liberal Argument Against Mandated Autonomous Cars’, which argues that such a law would be incompatible with classical liberalism, provided that the following condition holds: In the event where the car must ‘choose’ between running over a young person or an old person, or both, autonomous cars are programmed to respond by running over old people in order to save young (...) people. Such a law requiring the use of these cars, provided that these assumptions hold, would violate the important value in classical liberalism that all individuals ought to be treated equally before the law. The paper concludes by arguing that alternative ways of dealing with this problem come with their own set of unpalatable problems. (shrink)

Michael Dummett and Dag Prawitz have argued that a constructivist theory of meaning depends on explicating the meaning of logical constants in terms of the theory of valid inference, imposing a constraint of harmony on acceptable connectives. They argue further that classical logic, in particular, classical negation, breaks these constraints, so that classical negation, if a cogent notion at all, has a meaning going beyond what can be exhibited in its inferential use. I argue that Dummett gives (...) a mistaken elaboration of the notion of harmony, an idea stemming from a remark of Gerhard Gentzen's. The introduction-rules are autonomous if they are taken fully to specify the meaning of the logical constants, and the rules are harmonious if the elimination-rule draws its conclusion from just the grounds stated in the introduction-rule. The key to harmony in classical logic then lies in strengthening the theory of the conditional so that the positive logic contains the full classical theory of the conditional. This is achieved by allowing parametric formulae in the natural deduction proofs, a form of multiple-conclusion logic. (shrink)

In this collection of provocative essays, historians and literary theorists assess the influence of Michel Foucault, particularly his History of Sexuality, on the study of classics. Foucault's famous work presents a bold theory of sexuality for both ancient and modern times, and yet until now it has remained under-explored and insufficiently analyzed. By bringing together the historical knowledge, philological skills, and theoretical perspectives of a wide range of scholars, this collection enables the reader to explore Foucault's model of Greek culture (...) and see how well his interpretation accounts for the full range of evidence from Greece and Rome. Not only do the essays bring to light the assumptions, ideas, and practices that constituted the intimate lives of men and women in the ancient Mediterranean world, but they also demonstrate the importance of the History of Sexuality for fields as diverse as Greco-Roman antiquity, women's history, cultural studies, philosophy, and modern sexuality. The essays include "Situating The History of Sexuality" (the editors), "Taking the Sex Out of Sexuality: Foucault's Failed History" (Joel Black), "Incipit Philosophia" (Alain Vizier), "The Subject in Antiquity after Foucault" (Page duBois), "This Myth Which Is Not One: Construction of Discourse in Plato's Symposium" (Jeffrey S. Carnes), "Foucault's History of Sexuality: A Useful Theory for Women?" (Amy Richlin), "Catullan Consciousness, the 'Care of the Self,' and the Force of the Negative in History" (Paul Allen Miller), "Reversals of Platonic Love in Petronius' Satyricon" (Daniel B. McGlathery), and an essay from Dislocating Masculinity (Lin Foxhall). (shrink)

The focus of this paper are Dummett's meaning-theoretical arguments against classical logic based on consideration about the meaning of negation. Using Dummettian principles, I shall outline three such arguments, of increasing strength, and show that they are unsuccessful by giving responses to each argument on behalf of the classical logician. What is crucial is that in responding to these arguments a classicist need not challenge any of the basic assumptions of Dummett's outlook on the theory of meaning. (...) In particular, I shall grant Dummett his general bias towards verificationism, encapsulated in the slogan 'meaning is use'. The second general assumption I see no need to question is Dummett's particular breed of molecularism. Some of Dummett's assumptions will have to be given up, if classical logic is to be vindicated in his meaning-theoretical framework. A major result of this paper will be that the meaning of negation cannot be defined by rules of inference in the Dummettian framework. (shrink)

We formulate from first principles a theory of stochastic processes in configuration space. The fundamental equations of the theory are an equation of motion which generalizes Newton's second law and an equation which expresses the condition of conservation of matter. Two types of stochastic motion are possible, both described by the same general equations, but leading in one case to classical Brownian motion behavior and in the other to quantum mechanical behavior. The Schrödinger equation, which is derived here with (...) no further assumption, is thus shown to describe a specific stochastic process. It is explicitly shown that only in the quantum mechanical process does the superposition of probability amplitudes give rise to interference phenomena; moreover, the presence of dissipative forces in the Brownian motion equations invalidates the superposition principle. At no point are any special assumptions made concerning the physical nature of the underlying stochastic medium, although some suggestions are discussed in the last section. (shrink)

This paper returns to some themes found in David Mitrany's classical ‘functionalist’ approach to international politics, in order to reconstruct practical principles that might be applied to contemporary politics as well as debates in International Relations and international political theory. It attempts to do this through two moves — ‘restoration’ and ‘contemporary reconstruction’. In restoring some of the insights Mitrany provides us that have been somewhat obscured over time, the paper hopes to demonstrate the ‘function’ behind functionalism — that (...) its core assumptions as an approach (if not ‘theory’) to international politics can prove to be just as instructive today as they were during the several decades of their initial development by Mitrany. Reconstruction, however, is necessitated by the observation that some of Mitrany's aspirations for functional theory — namely that it would produce ‘bonds’ that not only transcend national communities, but provide for the unraveling of the nation-state system as we know it — were a bit utopian. Thus, the paper proposes several avenues to reconstruct classical functionalism for contemporary politics. The paper then discusses three small empirical illustrations where micro-political insights can be extracted and briefly analysed: peace camps, the Regional Cooperation Council of the former Yugoslavia, and a more detailed analysis of the so-called ‘surge’ strategy in the ongoing US-Iraq conflict. It concludes with a two-pronged discussion on how micro-politics might speak to current debates in international political theory, and some mechanisms for securing functional spaces. (shrink)

I begin by reviewing some recent work on the status of the geodesic principle in general relativity and the geometrized formulation of Newtonian gravitation. I then turn to the question of whether either of these theories might be said to ``explain'' inertial motion. I argue that there is a sense in which both theories may be understood to explain inertial motion, but that the sense of ``explain'' is rather different from what one might have expected. This sense of explanation is (...) connected with a view of theories---I call it the ``puzzleball view''---on which the foundations of a physical theory are best understood as a network of mutually interdependent principles and assumptions.

The problem of two relativistically-moving pointlike particles of constant mass is undertaken in an arbitrary Lorentz frame using the classical Lagrangian mechanics of Stückelberg, Horwitz, and Piron. The particles are assumed to interact at events along their world lines at a common “world time,” an invariant dynamical parameter which is not in general synchronous with the particle proper time. The Lorentz-scalar interaction is assumed to be the Coulomb potential (i.e., the inverse square spacetime potential) of the spacetime event separation. (...) The classical orbit equations are found in 1 + 1 spacetime dimensions in the hyperbolic angle coordinates for the reduced problem. The solutions to the reduced motion in these coordinates are the spacetime generalizations of the nonrelativistic Kepler solutions. and they introduce an invariant eccentricity which is a function of other known constants of the motion for the reduced problem. Solutions compatible with physical scattering are obtained by the assumption that the eccentricity is a given function of the ratio of the particle masses. (shrink)

I argue that there are two ways of construing Wittgenstein’s slogan that meaning is use. One accepts the view that the notion of meaning must be explained in terms of truth-theoretic notions and is committed to the epistemic conception of truth. The other keeps the notion of meaning and the truth-theoretic notions apart and is not committed to the epistemic conception of truth. I argue that Dummett endorses the first way of construing Wittgenstein’s slogan. I address the issue by discussing (...) two of Dummett’s arguments against the realist truth-theoretic conception of meaning: the manifestation argument and the argument for the unintelligibility of classical logic. I examine the dialectic of those arguments and show that they rest on the assumption that meaning needs to be explained in terms of truth-theoretic notions.Tvrdim da postoje dva načina shvaćanja Wittgensteinova slogana da je značenje upotreba.

It takes a fresh look at classical liberalism by exploring economic arguments in thinkers like Thomas Hobbes, Thomas Paine, John Trenchard and Thomas Gordon, who are not typically viewed as economic thinkers, and by highlighting the importance of Bernard Mandeville and Adam Smith in the development of interest-based liberalism. It also re-examines lesser-known economic tracts by thinkers such as John Locke, David Hume and John Stuart Mill in light of their more well-known political writings. With classical liberal assumptions still prominent in contemporary debates about economic justice, it is vital for every democratic citizen to understand the complex origins and development of the ideas that did so much to shape our world today.

A widespread view among physicists is that Bell’s theorem rests on an implicit assumption of “classicality,” in addition to locality. According to this understanding, the violation of Bell’s inequalities poses no challenge to locality, but simply reinforces the fact that quantum mechanics is not classical. The paper provides a critical analysis of this view. First we characterize the notion of classicality in probabilistic terms. We argue that classicality thus construed has nothing to do with the validity of classical (...) physics, nor of classical probability theory, contrary to what many believe. At the same time, we show that the probabilistic notion of classicality is not an additional premise of Bell’s theorem, but a mathematical corollary of locality in conjunction with the standard auxiliary assumptions of Bell. Accordingly, any theory that claims to get around the derivation of Bell’s inequalities by giving up classicality, in fact has to give up one of those standard assumptions. As an illustration of this, we look at two recent interpretations of quantum mechanics, Reinhard Werner’s operational quantum mechanics and Robert Griffiths’ consistent histories approach, that are claimed to be local and non-classical, and identify which of the standard assumptions of Bell’s theorem each of them is forced to give up. We claim that while in operational quantum mechanics the Common Cause Principle is violated, the consistent histories approach is conspiratorial. Finally, we relate these two options to the idea of realism, a notion that is also often identified as an implicit assumption of Bell’s theorem. (shrink)

I argue that in a classical universe, all the events that ever happen are encoded in each of the universe's parts. This conflicts with a statement which is widely believed to lie at the basis of relativity theory: that the events in a space-time region R determine only the events in R's domain of dependence but not those in other space-time regions. I show how, from this understanding, a new prediction method (which I call the &unknown;Smoothness Method&unknown;) can be (...) obtained which allows us to predict future events on the basis of local observational data. Like traditional prediction methods, this method makes use of so-called &unknown;ceteris paribus clauses&unknown;, i.e. assumptions about the unobserved parts of the universe. However, these assumptions are used in a way which enables us to predict the behaviour of open systems with arbitrary accuracy, regardless of the influence of their environment--which has not been achieved by traditional methods. In a sequel to this paper (Schmidt, 1998), I will prove the Uniqueness and Predictability Theorems on which the Smoothness Method is based, and comment in more detail on its mathematical properties.

Realizing that a world remade by techno-science and global capital stands in great need of practical wisdom as an antidote to various forms of modern hubris, scholars across the human sciences have taken a renewed interest in exploring how the classical virtue of prudence can be reformulated as a guide for postmodern practice. This volume brings together scholars in classics, political philosophy, and rhetoric to analyze prudence as a distinctive and vital form of political intelligence. Through case studies from (...) each of the major periods in the history of prudence, the authors identify neglected resources for political judgment in today's conditions of pluralism and interdependency. Three assumptions inform these essays: the many dimensions of prudence cannot be adequately represented in the lexicon of any single discipline; the Aristotelian focus on prudence as rational calculation needs to be balanced by the Ciceronian emphasis on prudence as discursive performance embedded in familiar social practices; and understanding prudence requires attention to how it operates through the communicative media and public discourses that constitute the political community.

In lieu of an abstract, here is a brief excerpt of the content:English Classical: The Reform of Poetry in Elizabethan England STEPHEN ORGEL Roger ascham, writing in the 1560s, in the course of a treatise on education, urged the reform of English poetry on classical models: “Our English tongue, in avoiding barbarous rhyming, may as well receive right quantity of syllables, and true order of versifying... as either Greek or Latin....”1 He cites as an example of right quantity (...) of syllables and true order of versifying this translation by the scholar and poet William Watson of a verse from the Odyssey: All travelers do gladly report great praise of Ulysses. For that he knew many men’s manners, and saw many cities. This does not sound much like English poetry, but if we count it out we can see that it does, more or less, follow the quantitative rules. The trouble is that the rules have little to do with English pronunciation. Vowels are long by position (followed by two consonants) regardless of how they are pronounced ; moreover, Watson makes vowels long if they are stressed (such as the a in “travelers” and “manners” and the i in “cities”), again regardless of how they are pronounced. For the Elizabethans, this was a problem not with the rules, but with English, both in its dissimilarity from the classical tongues and in the variety of spelling and pronunciation at the time—proponents of quantitative verse in English observe that a necessary first step would be to stabilize the language, as Gabriel Harvey wrote to Edmund Spenser, “there is no one more regular and justifiable direction, either for the assured and infallible certainty of our English artificial prosody particularly, or generally to bring our language into art and to arion 27.2 fall 2019 frame a grammar or rhetoric thereof, than first of all universally to agree upon one and the same orthography.”2 But even with a stable orthography, the application of quantitative rules to English is problematic. To begin with, it is not clear in what sense an English vowel can be said to be long or short—to consider the vowels in stressed syllables invariably long, as Watson does, is entirely arbitrary. There is obviously a difference between the a sound in “rat” and in “rate”; such vowels are now described as short and long, but in pronunciation, they may or may not be of equal extension : thus, the a in “rate” is not, in speaking, longer than the a in “rat,” it is simply pronounced differently; whereas the i in “rise” is certainly longer than the i in “rid.” If quantity means length, English vowels are too erratic to serve—Harvey observed to Spenser that in some quantitative hexameters Spenser had sent him, “the,” “ye” and “he” were treated as short, but “me” was long.3 The issue is especially vexed in the case of vowels that are long by position. The most common examples in English are the -ing endings of participles, which are invariably unaccented and stubbornly short when spoken. In fact, Thomas Campion confronted precisely this problem; and his way of dealing with it gives a clear sense of how willed the whole quantitative system in English necessarily was: For though we accent the second [syllable] of Trumpington short, yet is it naturally long, and so of necessity must be held of every composer.4 What can “naturally” mean here? Are the rules of Latin prosody laws of nature? Harvey had a clear sense of the practical problems, writing to Spenser, “in short, this is the very short and long: position neither maketh short nor long in our tongue,” and concludes that some other rule must be found for English “that should as universally and canonically hold amongst us as position doth with the Latins and Greeks.”5 The larger assumption behind Ascham’s and Harvey’s proposals for a new poetry was that the “barbarous” England 44 english classical of the time could be rectified by the application of classical rules. A return to the classics held out the promise of culture and civility—not only in poetry, of course, but poetry seemed a particularly clear example. Nobody thought the transformation would be easy; a hectoring... (shrink)

Plato believes in the existence of Forms—eternal models or exemplars of which objects in our world in time and space are copies, and his Theory of Forms lies at the center of his philosophy. But according to the common wisdom, Plato raised the Third Man objection against his own Theory of Forms in the Parmenides. According to this objection, each Form is supposed to have the very characteristic it is supposed to be , and this leads to an infinite regress (...) of each Form . This book defends the view that a mysterious plural phrase at Phaedo 74 shows that the Self-Predication Assumption is both plausible and leads to no infinite regress of Forms. The Self-Predication Assumption in Plato is an essential resource for scholars, specialists, and students with an interest in ancient philosophy and classics. (shrink)

This article investigates Charles Peirce’s development of logical calculi for classical propositional logic in 1880–1896. Peirce’s 1880 work on the algebra of logic resulted in a successful calculus for Boolean algebra. This calculus, denoted byPC, is here presented as a sequent calculus and not as a natural deduction system. It is shown that Peirce’s aim was to presentPCas a sequent calculus. The law of distributivity, which Peirce states in 1880, is proved using Peirce’s Rule, which is a residuation, inPC. (...) The transitional systems of the algebra of the copula that Peirce develops since 1880 paved the way to the 1896 graphical system of the alpha graphs. It is shown how the rules of the alpha system reinterpret Boolean algebras, answering Peirce’s statement that logical graphs supply a new system of fundamental assumptions to logical algebra. A proof-theoretic analysis is given for the connection betweenPCand the alpha system. (shrink)

Reingold and MerikleÕs (1988, 1990) critique of the classic dissociation paradigm identified several issues as inherent problems that severely undermine the utility of this paradigm. Erdelyi (2004) extending his prior analysis (Erdelyi, 1985, 1986) points out several additional factors that may complicate the interpretation of empirically obtained dissociations. The goal of the present manuscript is to further discuss some of these commonly neglected interpretive difficulties. Ó 2003 Elsevier Inc. All rights reserved.

The contemporary scientific and technological progress builds on the accomplishments of classical mechanics from the 19th century when the so-called ‘European scientific method and values’ were accepted practically by the whole educated world. Most scientific results and conclusions were reached based on the causal ontological approach proposed in principle already by Plato’s Socrates and developed further by Aristotle. Despite the late-modern paradigm shift in science, the topicality of the ontological approach proposed by Aristotle remains. On the other hand, 19th (...) and 20th century philosophers, mainly positivists such as Mach and Avenarius but also Schlick and Carnap, attempted to change this approach to unify scientific knowledge in accordance with an ideological, i.e. positivist outlook on reality. The authors place a special emphasis on the contribution of Rudolf Carnap and his interaction with Martin Heidegger. Three very different theories are applied to physical reality in the present: classical mechanics in the standard macroscopic realm, Copenhagen quantum mechanics in the microscopic realm, and special theory of reality in both realms in the case of systems consisting of objects having higher velocity values. Any explanation or description of transitions between different realms and theories had not been provided until now. Our paper describes the corresponding evolution in the modern period and identifies the underlying false philosophical assumptions and statements existing in today’s scientific systems. We will then demonstrate that one common theory for all realms of reality may exist; one that will be based fully on Hamilton equations. Only time change of particle impulse is to be determined by a corresponding force. All necessary characteristics of physical reality may be derived in such a case. Direct correlations of such physical approach to philosophy will be drawn. (shrink)

We analyze seemingly contradictory claims in the literature about the role played by decoherence in ensuring classical behavior for the chaotically tumbling satellite Hyperion. We show that the controversy is resolved once the very different assumptions underlying these claims are recognized. In doing so, we emphasize the distinct notions of the problem of classicality in the ensemble interpretation of quantum mechanics and in decoherence-based approaches that are aimed at addressing the measurement problem.

Primary to both ontology and epistemology is the attributional union that properties and relations have with their subjects. Yet, the tradition’s understanding of attribution has been assessed as shallow, and its contemporary analysis deemed locked in a non-progressing stalemate. Central here is the historically dominant __in___herence_/_constituent_ construal of attribution, what, I argue, has remained obscure and unattended as to its background assumptions and their implications. On the analysis offered herein, I make precise and detail errors of the defining (...) class='Hi'>assumptions of inherence theory and the _two-tiered nature_ it requires of attribution. Brought into relief will be the four elements involved in every attributional union, and what are the errors in a sequence of collapsing identities among them that define inherence theory. Along the way, clarification and warrant is provided for the alternative theses and their implications defining an __ad___herence_ theory of attribution, key features synopsized in the last section.

Weatherson argues that whoever accepts classical logic, standard mereology and the difference between vague objects and any others, should conclude that there are no vague objects. Barnes and Williams claim that a supporter of vague objects who accepts classical logic and standard mereology should recognize that the existence of vague objects implies indeterminate identity. Even though it is not clearly stated, they all seem to be committed to the assumption that reality is ultimately constituted by mereological atoms. This (...) assumption is not granted by standard mereology which instead remains silent on whether reality is atomic or gunky; therefore, I contend that whoever maintains classical logic, standard mereology and the difference between vague objects and any others, is not forced to conclude with Weatherson that there are no vague objects; nor is she compelled to revise her point of view according to Barnes and Williams’s proposal and to accept that the existence of vague objects implies indeterminate identity.

Historians of science have long considered the very idea of a law-governed universe to be the relic of a bygone intellectual culture that took it largely for granted that a divine lawmaker existed. Similarly, many philosophers of science today insist that the notion of a law of nature is fraught with implausibly theological assumptions, preferring instead to treat them as theoretical axioms in an optimal description of nature's regularities, or else as robust patterns of causal connections or causal powers (...) whose status can be reconciled to the stringent demands of metaphysical naturalism. Yet the metaphor of lawhood has proven more difficult to dislodge than the theistic commitments it once presupposed, not least because it preserves the widespread intuition that the task of scientific inquiry is not to stipulate the difference between a lawful and an accidental regularity in nature, but to discover it. Taking its cue from the repeated failure to find naturalistic alternatives to divine lawmaking, this book undertakes a retrieval and reappraisal of a high-scholastic philosophy of nature that grounds lawlike regularities in the conceptual and causal powers of God and, having done so, concludes that the metaphysical framework of classical theism yields a more powerful and parsimonious explanation of the rhythms and patterns of the natural world than its secular rivals.

This book argues that Western studies of East-Asian politics are generally flawed due to their adherence to the premise that liberal democracy is the best form of governance. The book rejects the three main schools of the Western interpretation of Oriental politics and instead examines the border-transcending powers of Confucianism that have, over more than twenty-two centuries, transformed the politics of East Asia. By circumventing the fundamental methodical and ethical assumptions of the Anglophone hegemonic discourse on the politics of (...) the non-Western world, it effectively presents an alternative to traditional Western interpretations of East Asian politics. Written in an erudite and engaging way this book will be a valuable resource for scholars and students of Asian studies, Asian politics and political philosophy. (shrink)

A well-known result, going back to the twenties, states that, under some reasonable assumptions, any logic can be characterized as the set of formulas satisfied by a matrix 〈,F〉, whereis an algebra of the appropriate type, andFa subset of the domain of, called the set of designated elements. In particular, every quasi-classical modal logic—a set of modal formulas, containing the smallest classical modal logicE, which is closed under the inference rules of substitution and modus ponens—is characterized by (...) such a matrix, wherenow is a modal algebra, andFis a filter of. If the modal logic is in fact normal, then we can do away with the filter; we can study normal modal logics in the setting of varieties of modal algebras. This point of view was adopted already quite explicitly in McKinsey and Tarski [8]. The observation that the lattice of normal modal logics is dually isomorphic to the lattice of subvarieties of a variety of modal algebras paved the road for an algebraic study of normal modal logics. The algebraic approach made available some general results from Universal Algebra, notably those obtained by Jónsson [6], and thereby was able to contribute new insights in the realm of normal modal logics [2], [3], [4], [10].The requirement that a modal logic be normal is rather a severe one, however, and many of the systems which have been considered in the literature do not meet it. For instance, of the five celebrated modal systems, S1–S5, introduced by Lewis, S4 and S5 are the only normal ones, while only SI fails to be quasi-classical. The purpose of this paper is to generalize the algebraic approach so as to be applicable not just to normal modal logics, but to quasi-classical modal logics in general. (shrink)

The classical limit is fundamental in quantum mechanics. It means that quantum predictions must converge to classical ones as the macroscopic scale is approached. Yet, how and why quantum phenomena vanish at the macroscopic scale is difficult to explain. In this paper, quantum predictions for Greenberger–Horne–Zeilinger states with an arbitrary number q of qubits are shown to become indistinguishable from the ones of a classical model as q increases, even in the absence of loopholes. Provided that two (...) reasonable assumptions are accepted, this result leads to a simple way to explain the classical limit and the vanishing of observable quantum phenomena at the macroscopic scale.

On the assumption that theistic religious commitment takes place in the face of evidential ambiguity, the question arises under what conditions it is permissible to make a doxastic venture beyond one’s evidence in favour of a religious proposition. In this paper I explore the implications for orthodox theistic commitment of adopting, in answer to that question, a modest, moral coherentist, fideism. This extended Jamesian fideism crucially requires positive ethical evaluation of both the motivation and content of religious doxastic ventures. I (...) suggest that, even though the existence of horrendous evil does not resolve evidential ambiguity in favour of atheism, there are reasonable value commitments that would preclude those who hold them from satisfying extended Jamesian fideist conditions for committing themselves to classical theism. I then begin a discussion of a possible revisionary theistic alternative (in the Christian tradition) which – one might hope – may meet those conditions. An earlier, shorter, version of this paper was delivered as a keynote address at the APA Pacific 2007 Mini-Conference on Models of God. (shrink)

In the analytic Philosophy of Religion, much ink has been spilt on the existence of some sort of supernatural reality. Such work is usually done by theists; those that find classical theism to be probably true. It is my contention that theism is unjustly privileged by many in the field, even when supernaturalism has been – competently or incompetently – argued for. As such, I present a series of challenges for the theist, finding them to be insuperable at present. (...) The first such challenge concerns the challenge of polytheism. Polytheism is often very casually overlooked on the basis that monotheism is ‘simpler’. Recognising that such simplicity is not necessarily truth-conducive, I argue that polytheism, as a catch-all hypothesis, ought to be preferred. The second challenge proceeds from an assumption not only of supernaturalism, but also of monotheism. There are infinitely many monotheistic alternatives to theism, which can be conceived by simply tweaking the typical attributes of God. Again, simplicity is typically appealed to, and again found to be unhelpful. Furthermore, there are the deistic alternatives to consider also, many of which are seemingly more probable than theism. Finally, I consider the pantheistic god models, deciding that pantheisms are generally more robust and make fewer ad hoc assumptions about the world. As an aside, I concisely discuss the difficulties in moving from theism to Christian theism, which includes an argument against miracles, and a brief explanation of the increasing trend of questioning Jesus’ historical existence.

I argue that no classical theist, and even more no orthodox Christian, should affirm compatibilism in our world. However plausible compatibilism may be on atheistic assumptions, bringing God into the equation should radically alter our judgment on this ongoing controversy. In particular, if freedom and determinism are compatible, then God could have created a world in which all persons freely did only the good at all times. Given this implication of compatibilism, three issues that are already challenging become (...) extraordinarily more difficult, if not insuperable, namely: moral responsibility, the problem of evil, and the orthodox doctrine of eternal damnation.

A certain view of Anglo-American liberal political theory has been commonplace for a couple of generations. It is said that the philosophical foundations of contractarian liberalism lie in the 17th century, chiefly in the formulations given to it by Hobbes and Locke. But for two distinct reasons these 17th century formulations fail to provide an adequate basis for contemporary political theory. First, the development of our political and economic institutions in the past two or three hundred years has made it (...) impossible to accept a theory which assumes a minimal, laissez-faire state and a highly competitive economy. Second, the individualist psychological and moral assumptions of the theory are highly dubious if not clearly false.In A Theory of justice John Rawls attempts to provide the systematic revision which liberalism so clearly needs. The revisionist intent of Rawls’ work has not received the attention it deserves, except by critics of the right who deny that such revision is needed. (shrink)

If no property of a system of many particles discriminates among the particles, they are said to be indistinguishable. This indistinguishability is equivalent to the requirement that the many-particle distribution function and all of the dynamic functions for the system be symmetric. The indistinguishability defined in terms of the discrete symmetry of many-particle functions cannot change in the continuous classical statistical limit in which the number density n and the reciprocal temperature β become small. Thus, microscopic particles like electrons (...) must remain indistinguishable in the classical statistical limit although their behavior can be calculated as if they move following the classical laws of motion. In the classical mechanical limit in which quantum cells of volume (2πħ)3 are reduced to points in the phase space, the partition functionTr{exp(−βĤ) for N identical bosons (fermions) approaches (2πħ)−3N(N!) ∫ ... ∫ d3r1 d3p1 ... d3rN d3pN exp(−βH). The two factors, (2πħ)−3N and (N!)−1, which are often added in anad hoc manner in many books on statistical mechanics, are thus derived from the first principles. The criterion of the classical statistical approximation is that the thermal de Broglie wavelength be much shorter than the interparticle distance irrespective of any translation-invariant interparticle interaction. A new derivation of the Maxwell velocity distribution from Boltzmann's principle is given with the assumption of indistinguishable classical particles. (shrink)
