We also show that the notions of maximal \-ideal, prime \-ideal, and falsity ideal coincide.

In her ‘On the apparent paradox of ideal theory’, Laura Valentini combines three supposedly plausible premises to derive the paradoxical result that ideal theory is both unable to, and indispensable for, guiding action. Her strategy is to undermine one of the three premises by arguing that there are good and bad kinds of ideal theory, and only the bad kinds are vulnerable to the strongest version of their opponents’ attack. By undermining one of the three premises she (...) releases ideal theorists from the paradox, which is as follows. (1) Any sound theory of justice is action-guiding. (2) Any sound theory of justice is ideal. (3) Any ideal theory fails to be action-guiding. Here I shall respond to Valentini in two ways. First, I shall show that both (1) and (2) are false. The falsity of either is sufficient to release ideal theorists from the paradox. Second, I shall show that Valentini’s response to (3) can be extended, because her bad kinds of ideal theory do not necessarily fail to guide action. The cumulative effect of my arguments further strengthens Valentini’s support of ideal theory. I will deal with premises (1) and (2) in Sections I and II, and (3) in Section III. (shrink)

Idealizations are ubiquitous in physics. They are distortions or falsities that enter into theories, laws, models, and scientific representations. Various questions suggest themselves: What are idealizations? Why do we appeal to idealizations and how do we justify them? Are idealizations essential to physics and, if so, in what sense and for which purpose? How can idealizations provide genuine understanding? If our motivation for believing in the existence of unobservable entities like electrons and quarks is that they are indispensable to our (...) best theories, should we also believe in the existence of indispensable idealizations? This Element will tackle such questions and offer an opinionated and selective introduction to philosophical issues concerning idealizations in physics. Topics to be covered include the concept of and reasons for introducing idealization, abstraction, and approximation, possible taxonomy and justification, and application to issues of mathematical Platonism, scientific realism, and scientific understanding.

This paper explores one way in which the meta-problem may shed light on existing debates about the hard problem (though not directly on the hard problem itself). I'll argue that the possibility of a suitable agent without problem intuitions would undercut the dialectical force of arguments against physicalism. Standard antiphysicalist arguments begin from intuitions about what's ideally conceivable, and argue from there to the falsity of physicalism. For these arguments to be dialectically effective, there must be a shared conception (...) of what ideal conceivability consists in. Unfortunately, proposed accounts of ideal conceivability all make reference to an unexplained 'intuitive' notion of idealization. Consideration of the meta-problem reveals that, when it comes to the hard problem, intuitions about idealization are essentially theory-laden. There is no neutral basis for determining whether agents with or without problem intuitions are more rationally ideal. (shrink)

The problem for the scientist created by using idealizations is to determine whether failures to achieve experimental fit are attributable to experimental error, falsity of theory, or of idealization. Even in the rare case when experimental fit within experimental error is achieved, the scientist must determine whether this is so because of a true theory and fortuitously canceling idealizations, or due to a fortuitous combination of false theory and false idealizations. For the engineer, the problem seems rather different. Experiment (...) for the engineer reveals the closeness of predictive fit that can be achieved by theory and idealization for a particular case. If the closeness of fit is good enough for some practical purpose, the job is done. If not, or there are reasons to consider variation, then the engineer needs to know how well the experimentally determined closeness of fit will extrapolate to new cases. This paper focuses on engineering measures of closeness of fit and the projectibility of those measures to new cases. (shrink)

According to Stoic moral psychology, emotions are cognitive responses to perceived value in the contingent world. This dissertation begins by defending a contemporary version of this descriptive theory; it then proceeds with a critique of the Stoics' normative thesis that emotions involve amorally deplorable kind of cognitive error. I distinguish two senses in which this thesis is historically put forward, and show that both are thematically pertinent. The structural variant, as I call it, is a qualified critique of the particular (...) cognitive flaws to which emotions are liable; the fundamental argument, on the other hand, is that emotions are categorically unreliable. My goal in the rest of the dissertation is to respond to each aspect of normative Stoicism with a positive account of how it might be possible for a moral agent to avoid false emotion without doing away with emotion altogether. This means explaining how a person's emotional perception might become reliable rather than sentimental within a given moral context, and indicating what axiological conditions must generally obtain if emotion is justifiable in any case. In doing so, I draw largely upon Kierkegaard's pseudonymous and signed writings, while also engaging with other relevant philosophical texts along the way. I argue that a morality of virtue and narrative awareness is necessary for accurate emotional perception; then, I attempt to define the conditions on which a qualified value realism might be tenable. It is one thing to argue for the importance of emotion in human life, as a number of recent studies have done, but it is quite another to show how we might cultivate truthful, and avoid false, emotion. The outcome of this inquiry into the possibility of reliable emotion is a positive account of the ideal state in which one could trust oneself to be rational in being passionate. (shrink)

Ordinary language and scientific language enable us to speak about, in a singular way, what we recognize not to exist: fictions, the contents of our hallucinations, abstract objects, and various idealized but nonexistent objects that our scientific theories are often couched in terms of. Indeed, references to such nonexistent items-especially in the case of the application of mathematics to the sciences-are indispensable. We cannot avoid talking about such things. Scientific and ordinary languages thus enable us to say things about Pegasus (...) or about hallucinated objects that are true, such as "Pegasus was believed by the ancient Greeks to be a flying horse," or "That elf I'm now hallucinating over there is wearing blue shoes." Standard contemporary metaphysical views and semantic analyses of singular idioms on offer in contemporary philosophy of language have not successfully accommodated these routine practices of saying true and false things about the nonexistent while simultaneously honoring the insight that such things do not exist in any way at all. That is, philosophers often feel driven to claim that such objects do exist, or they claim that all our talk isn't genuine truth-apt talk, but only pretence. This book reconfigures metaphysics in radical ways that allow the accommodation of our ordinary ways of speaking of what does not exist while retaining the absolutely crucial presupposition that such objects exist in no way at all, have no properties, and so are not the truth-makers for the truths and falsities that are about them.

Truth implies mind because falsity does and the same analysis must be given of each. Some philosophers (Aristotle, Brentano) express this by saying that ‘true’ and ‘false’ apply strictly speaking to judgments and derivatively to everything else. A consequence of this is that all non‐judgmental senses of ‘true’ and ‘false’ include some relation to a judgment. But counterexamples to this occur. So an alternative assay must be sought which both covers all cases and retains the idea that truth is (...) mind‐dependent. Under this correction, something is true if and only if it conforms to an ideal standard or measure. This broader view of truth is compatible with realism and conceptualism but not with nominalism. If there are independent reasons for rejecting realism, it follows that conceptualism is true and universals exist only in minds. (shrink)

This paper develops and defends a new argument against physicalist views of consciousness: the inconceivability argument. The argument has two main premises. First, it is not (ideally, positively) conceivable that phenomenal truths are grounded in physical truths. (For example, one cannot positively conceive of a situation in which someone has a vivid experience of pink wholly in virtue of the movements of colorless, insentient atoms.) Second, (ideal, positive) inconceivability is a guide to falsity. I attempt to show that (...) the inconceivability argument enjoys a significant advantage over the more familiar conceivability argument. One can reasonably endorse the inconceivability argument without endorsing the conceivability argument, but one cannot reasonably endorse the conceivability argument without also endorsing the inconceivability argument.

Epistemologists can be divided into two camps: those who think that nothing short of certainty or (subjective) probability 1 can warrant assertion and those who disagree with this claim. This paper addressed this issue by inquiring into the problem of setting the probability threshold required for assertion in such a way that that the social epistemic good is maximized, where the latter is taken to be the veritistic value in the sense of Goldman (Knowledge in a social world, 1999). We (...) provide a Bayesian model of a test case involving a community of inquirers in a social network engaged in group deliberation regarding the truth or falsity of a proposition $p.$ p . Results obtained by means of computer simulation indicate that the certainty rule is optimal in the limit of inquiry and communication but that a lower threshold is preferable in less idealized cases.

This paper treats some of the issues raised by Putnam's discussion of, and claims for, quantum logic, specifically: that its proposal is a response to experimental difficulties; that it is a reasonable replacement for classical logic because its connectives retain their classical meanings, and because it can be derived as a logic of tests. We argue that the first claim is wrong (1), and that while conjunction and disjunction can be considered to retain their classical meanings, negation crucially does not. (...) The argument is conducted via a thorough analysis of how the meet, join and complementation operations are defined in the relevant logical structures, respectively Boolean- and ortholattices (3). Since Putnam wishes to reinstate a realist interpretation of quantum mechanics, we ask how quantum logic can be a logic of realism. We show that it certainly cannot be a logic of bivalence realism (i.e., of truth and falsity), although it is consistent with some form of ontological realism (4). Finally, we show that while a reasonable explication of the idealized notion of test yields interesting mathematical structure, it by no means yields the rich ortholattice structure which Putnam (following Finkelstein) seeks.

In lieu of an abstract, here is a brief excerpt of the content:Did Hobbes Have a Semantic Theory of Truth? WILLEM R. DEJONG 1. INTRODUCTION THE qUESTIONRAISEDin the title of this article may strike the reader as a bit anachronistic. A phrase like 'semantic theory of truth' evokes associations with rather recent developments in logic, especially the work of Alfred Tarski. Nevertheless, it is generally agreed that Hobbes made important observations of a semantical nature. Moreover, in an interesting article still (...) frequently referred to, R. M. Martin has argued that Hobbes "has in mind a clear-cut semantical concept of truth."' Examining Hobbes's semantical ideas somewhat more closely than Martin did, T6rnebohm has given a more precise characterization of Hobbes's view on truth and falsity; he speaks of Hobbes's comprehension theory of truth. ~One of the main purposes of this article is to investigate whether such a theory is correctly attributed to Hobbes. For Tarski 'true' and 'false' are predicates of (declarative) sentences) But this is not enough to speak of a semantic theory of truth: The leading idea behind Tarski's fundamental work in the field of semantics is (a restricted version of) the principle of compositionality. This principle, also known as Frege's principle, says that the semantic value of a (complex) expression is a function of the semantic values of the syntactic (and categorematic) parts it is ' R. M. Martin, "On the Semantics of Hobbes," Philosophyand PhenomenologicalResearch 14 095314): 2o5-11, esp. ~o7, 211. Cf. I. C. Hungerland and G. R. Vick, "Hobbes's Theory of Language, Speech and Reasoning," in ThomasHobbes:Computatwsire Logica--Logic, translated and commentary by A. Martinich, ed. and introduced by I. C. Hungerland and G. R. Vick (New York: 1981), 15--167, esp. 17, 121-22. 9 H. T6rnebohm, "A Study in Hobbes' Theory of Denotation and Truth," Theor~a26 (196o): 53-7o; see p. 66. 3 A.

Moreover, in the case of linguistic expressions which are (deciarative ) sentences this semantic value should be its truth-value. 4 As we shall see, Hobbes's theory of propositions is basically a theory of subject-predicate propositions. It is therefore reasonable to qualify his theory of truth as a semantic one only if it satisfies Frege's principle to a certain extent. Ideally, this means that the truth-value of subject-predicate propositions should be conceived as a function of the semantic interpretations of its subject and predicate. In the next three sections I will concentrate principally on the logicosyntactical aspects of language. I will then discuss successively the general structure of propositions, the various sorts of names, and the syntax of Hobbes's theory of propositions. Section 5 is devoted to Hobbes's theory of truth as interpreted by Martin and T0rnebohm. The outcome of this examination makes it necessary to break away from Martin's restricted conception of semantics. Martin, like Tarski, takes semantics as "semantics in the narrower sense," i.e., as the discipline Quine refers to as the theory of reference. 5 However, sometimes this term is used in a broader sense; the field of semantics is taken then to include the theory of meaning too. Although the wording differs frequently, the distinction between meaning and reference is almost a constant in the history of thinking about language. On the side of meaning one finds terms like connotation, intension, conception, signification and analyticity, while terms like naming, denoting, extension (and sometimes again signification) are ]inked to the notion of reference. In the Computatio sive Logica, the first part of De Corpore, containing Hobbes's most mature work on the philosophy of language, this opposition is displayed by way of a distinction between, on the one side, nominare, denotare and appellare and, on the other side, significare. Hobbes's view of the significative, as opposed to the denotative, role of linguistic expressions is treated in sections 6, 7, and 8. There it will be shown that Hobbes's radical nominalism is decisive for his doctrine of signification; moreover, this nominalism raises serious problems for the relation... (shrink)

Mathematics for Hume is the exemplary field of demonstrative knowledge. Ideally, this knowledge is a priori as it arises only from the comparison of ideas without any further empirical input; it is certain because demonstration consist of steps that are intuitively evident and infallible; and it is also necessary because the possibility of its falsity is inconceivable as it would imply a contradiction. But this is only the ideal, because demonstrative sciences are human enterprises and as such they (...) are just as fallible as their human practitioners. According to the reading suggested here, Hume develops a radical sceptical challenge for mathematics, and thereby he undermines the knowledge claims associated with demonstrative reasoning. But Hume does not stop there: he also offers resources for a sceptical solution to this challenge, one that appeals crucially to social practices, and sketches the social genealogy of a community-wide mathematical certainty. While explaining this process, he relies on the conceptual resources of his faculty psychology that helps him to distinguish between the metaphysics and practices of mathematical knowledge. His account explains why we have reasons to be dubious about our reasoning capacities, and also how human nature and sociability offers some remedy from these epistemic adversities. (shrink)

This paper is devoted to present Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method for multi-attribute group decision making under rough neutrosophic environment. The concept of rough neutrosophic set is a powerful mathematical tool to deal with uncertainty, indeterminacy and inconsistency. In this paper, a new approach for multi-attribute group decision making problems is proposed by extending the TOPSIS method under rough neutrosophic environment. Rough neutrosophic set is characterized by the upper and lower approximation operators and (...) the pair of neutrosophic sets that are characterized by truth-membership degree, indeterminacy membership degree, and falsity membership degree. In the decision situation, ratings of alternatives with respect to each attribute are characterized by rough neutrosophic sets that reflect the decision makers’ opinion. Rough neutrosophic weighted averaging operator has been used to aggregate the individual decision maker’s opinion into group opinion for rating the importance of attributes and alternatives. Finally, a numerical example has been provided to demonstrate the applicability and effectiveness of the proposed approach. (shrink)

A starting point for the sort of alethic epistemological approach that dominates both historical and contemporary western philosophy is that epistemic norms, standards, or ideals are to be characterized by appeal to some kind of substantively normative relationship between belief and truth. Accordingly, the alethic epistemologist maintains that false beliefs are necessarily defective, imperfect, or flawed, at least from the epistemic perspective. In this paper, I develop an action-oriented alternative to the alethic approach, an alternative that is inspired by and (...) jives with the kind of thinking that underwrites promising and increasingly popular enactive or embodied research programs in cognitive science. Moreover, I argue that the proponent of an action-oriented epistemological approach ought to deny that falsity, in and of itself, necessarily constitutes a kind of epistemic imperfection in belief. The action-oriented epistemologist ought to embrace the possibility that there are epistemically flawless false beliefs. (shrink)

This paper offers an interpretation of Spinoza's theory of ideas as a theory of power. The consideration of ideas in terms of force and vitality figures ideology critique as a struggle within the power of thought to give life support to some ideas, while starving others. Because ideas, considered absolutely on Spinoza's terms, are indifferent to human flourishing, they survive, thrive, or atrophy on the basis of their relationship to ambient ideas. Thus, the effort to think and live well requires (...) attention to the collective dimensions of thinking life, where "collective" refers to a transpersonal accumulation of ideal power that includes human as well as nonhuman beings. Because it is a matter of force and power rather than truth and falsity, the project of thinking otherwise entails an effort to displace and to reorganize ideas that is best undertaken by coordinating and galvanizing many thinking powers.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 11.1 (2004) 55-64 [Access article in PDF] Delusions and Discourse:Moving beyond the Constraints of the Modernist Paradigm David J. Harper This special issue provides a good opportunity to reflect on the range of views about delusions,1 and it is good to see all the authors taking the issue of how to approach this topic seriously. Here I wish to argue that the traditional psychiatric view (...) of delusions is problematic. In the first half of this article I will group my comments on the issues raised by the papers by Klee and Bayne and Pacherie together as I think that, for their differences, they share modernist philosophical assumptions. I will argue that the modernist paradigm runs into considerable problems in considering beliefs felt by some to be unusual and I will go on to argue that we need to move beyond this paradigm and embrace different approaches, of which the work by Georgaca is an exemplar. The Trouble with (traditional Views of) Delusions The traditional psychiatric view of delusion has come under increasing attack over recent years. As Georgaca has noted, a number of problems with the assumptions in definitions of delusion can be identified when they are viewed from a social constructionist perspective (Georgaca 2000, 2004; Harper 1992, 1996; Heise 1988). For convenience I will group these under four main headings. They Are Based on a Naively Realist View of the World The criterion of inaccuracy or falsity implies that deciding on the veracity of a belief is a relatively unproblematic matter. However, the reality of claims does not always seem so important in judgments about whether a belief is delusional or not. For example, there is little evidence that mental health professionals systematically investigate the basis for people's beliefs; rather, they decide whether a belief is plausible. Thus Maher has argued that the assessment of the plausibility of beliefs is "typically made by a clinician on the basis of "common sense," and not on the basis of a systematic evaluation of empirical data" (1992, 261). He notes that it is not "customary to present counterevidence to the patient; it is not even common to present vigorous counterargument" (1992, 261) and there appears to be some empirical evidence of this (McCabe et al. 2002). Here then, we begin to see [End Page 55] how psychiatry, while claiming to have the power to judge the truth of beliefs on the basis of its status as an empirical scientific discipline, can be seen to make judgments on the basis of common sense and taken-for-granted social and cultural assumptions.Some commentators have suggested that delusions should be identified less by whether they seem to accord with reality but more by whether a person gives evidence for their belief (Gillett 1995; Spitzer 1990). However, this seems to be based on an idealized view of how people manage their beliefs in everyday life. For example, I would question how many of us have evidence for many of the beliefs (e.g., political, ethical, religious, etc.) we hold dear; indeed it would be hard to think of what evidence we could have for some of them (e.g., religious and ethical beliefs). Some recent work has suggested that the diagnosis of delusion is made on the basis of how people with delusions talk and interact; for example, some have argued that they do not appear to appreciate the hearer's point of view (Palmer 2000). However, here and in previous work, Georgaca (2000, 2004) has shown that people with delusions are able to talk about and negotiate disagreements about their beliefs and that many disputes of fact cannot be settled in conversation. People Said to Have Delusions Are Seen to Vary in the Conviction With Which Those Beliefs Are Held There is evidence that people considered to be deluded vary in the conviction with which they hold beliefs (Garety 1985) and can also be persuaded to modify their beliefs if this is conducted in a sensitive and collaborative manner (e.g., Chadwick, Birchwood, and Trower 1996). This... (shrink)

In his 1982 book Wittgenstein on Rules and Private Language, Saul Kripke develops a famous argument that purports to show that there are no facts about what we mean by the expressions of our language: ascriptions of meaning, such as “Jones means addition by ‘+’” or Smith means green by ‘green’”, are according to Kripke’s Wittgenstein neither true nor false. Kripke’s Wittgenstein thus argues for a form of non-factualism about ascriptions of meaning: ascriptions of meaning do not purport to state (...) facts. Define semantic realism to be the view that ascriptions of meaning are apt to be assessed in terms of truth and falsity, and are, at least in some instances, true. Semantic realism, thus defined, is a form of cognitivism about semantic judgement, according to which judgements ascribing meaning express beliefs, states apt for assessment in terms of truth and falsity. Kripke’s Wittgenstein thus argues against semantic realism, and in favour of a form of semantic non-cognitivism.1 En route to semantic non-cognitivism, Kripke’s Wittgenstein argues against dispositionalist theories of meaning, which hold something roughly along the lines of the following: Jones means magpie by “magpie” if and only if Jones is disposed to apply “magpie” to magpies in ideal conditions (where the ideal conditions can be specified in terms that don’t presuppose the notion of meaning, and are such that in those conditions Jones applies “magpie” to a thing if and only if that thing is a magpie).

Hilary putnam has tried to refute the realist doctrine that the operational verification of a theory never logically precludes its objective falsity by means of an argument involving model-theoretic considerations. in this paper it is first shown that this argument does not work if the theory in question is open to revision. next it is argued that a realist need not and should not admit the notion of the sort of unrevisable, ideal theory required for the purposes of (...) putnam's argument.

All economic models involve abstractions and idealisations. Economic theory itself does not tell which idealizations are truly fatal or harmful for the result and which are not. This is why much of what is seen as theoretical contribution in economics is constituted by deriving familiar results from different modelling assumptions. If a modelling result is robust with respect to particular modelling assumptions, the empirical falsity of these particular assumptions does not provide grounds for criticizing the result. In this paper (...) we demonstrate how derivational robustness analysis does carry epistemic weight and answer criticism concerning its non-empirical nature and the problematic form of the required independence of the ways of derivation. The epistemic rationale and importance of robustness analysis also challenge some common conceptions of the role of theory in economics. (shrink)

Assuming that the target of theory oriented empirical science in general and of nomic truth approximation in particular is to characterize the boundary or demarcation between nomic possibilities and nomic impossibilities, I have presented, in my article entitled “Models, postulates, and generalized nomic truth approximation” :3057–3077, 2016. 10.1007/s11229-015-0916-9), the ‘basic’ version of generalized nomic truth approximation, starting from ‘two-sided’ theories. Its main claim is that nomic truth approximation can perfectly be achieved by combining two prima facie opposing views on theories: (...) the traditional view: theories are postulates that exclude certain possibilities from being realizable, enabling explanation and prediction and the model view: theories are sets of models that claim to represent certain realizable possibilities. Nomic truth approximation, i.e. increasing truth-content and decreasing falsity-content, becomes in this way revising theories by revising their models and/or their postulates in the face of increasing evidence. The basic version of generalized nomic truth approximation is in many respects as simple as possible. Among other things, it does not take into account that one conceptual possibility may be more similar to another than a third one. However, for example, one theory may include a possibility that is more similar to a wrongly not included possibility than another theory can offer. Similarly, for wrongly not excluded possibilities. In this article it will be shown that such ‘refined’ considerations can be taken into account by adapted clauses based on a ternary similarity relation between possibilities. This allows again abductive conclusions about refined truth approximation if a theory is persistently more successful in the refined sense than another. It will also be indicated and illustrated that this refined approach enables a specification to the effect that refined truth approximation can be obtained by the method of idealization and subsequent concretization. Finally, the basic and the refined approach will be evaluated with regard to some general principles and objections that have been discussed in the literature. (shrink)

In this brief essay, we clarify Cohen’s ‘Facts and Principles’ argument, and then argue that the objections posed by two recent critiques of Cohen—Robert Jubb (Res Publica 15:337–353, 2009) and Edward Hall (Res Publica 19:173–181, 2013)—look especially vulnerable to the charge of being self-defeating. It may still be that Cohen’s view concerning facts and principles is false. Our aim here is merely to show that two recent attempts to demonstrate its falsity are unlikely to succeed.

Kant's theory of judgment involves his answer to the question "How is knowledge of the pattern underlying intentional strategies of objective - true and justified - representation of empirical events possible?" When we problematize this question, the problem of the scope of our notion of consistency in empirical reasoning emerges. We will argue in this article that Kant's theory includes a thesis about the circular nature of our patterns of consistency, based on the ability to protect the conceptual presuppositions that (...) harmonize knowledge of truth as opposed to falsity in any paradigm of theoretical reflection. This thesis allows Kant to develop a foundationalism about the knowledge of the content of judgments (the ability to recognize conceptual correctness or rule consistency) without committing to a static and transcendent view of the ideal object of our assertion strategies. In our view, this view is still one of the most competitive in describing the necessary - though not static - status of the propositions of empirical science. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 25.2 (2001) 251-277 [Access article in PDF] Hans Christian Andersen's Fish Out of Water Nancy Easterlin I Now that Darwinian literary criticism is on the horizon, the natural human tendency to codify manifests itself in calls to summarize succinctly what such an approach entails. Though clarity is always to be praised, bioevolutionary critics need to guard against the reductiveness that has beleaguered attempts at a scientifically (...) grounded literary criticism since the early twentieth century; most especially, we should think twice about limiting the interpretation of complex and varied works to selected sociobiological themes divorced from other biocultural considerations. David Sloan Wilson makes much the same point to students of evolution when he quotes Celia Heyes in a recent review of Evolutionary Psychology, David Buss's new textbook: "When I first encountered the term 'evolutionary psychology,' I thought it referred to the study of how mind and behavior evolved. But I was mistaken. In current usage, 'evolutionary psychology' refers exclusively to research on human mentality and behavior, motivated by a very specific, nativist-adaptationist interpretation of how evolution operates." 1If, as D. S. Wilson suggests, evolutionary psychology thus narrowly defined threatens to produce a limited understanding of human mind and behavior and, in the process, fragment the discipline of psychology further, how much less potentially productive is such an approach for those of us whose central objects of study, cultural artifacts, are as the products of behavior even further removed from the study of mind? Leda Cosmides and John Tooby are most explicit about the falsity of assuming that psychological adaptations determine behavior. This being so, it seems impossible that such adaptations could determine the [End Page 251] meaning of artworks, which are themselves the products of complex human behaviors. As I hope this discussion of Hans Christian Andersen's "Little Mermaid" will demonstrate, an approach to aesthetics strictly following the lead of evolutionary psychology as currently defined, while supplying valuable general insights about the motives for artistic behaviors and the cognitive processes engaged in them, cannot by itself inform us about the meaning of individual artworks. This is a crucial issue, since interpretation is the fundamental pursuit of scholars in fields like mine, literary studies.Putting the question of interpretive frutifulness aside for the moment, it can be said unequivocally that criticism that fails to be sensitive to mutation and change is not properly Darwinian. Evolutionary psychology and sociobiology themselves maintain that our psychic architecture is comprised of domain-specific competences; the result, as E. O. Wilson points out, is that the human mind is not designed to understand reality but is instead an instrument for survival and reproduction. 2 "Natural selection," says Michael Ruse, "works in a gerry-building fashion, making do with what it has at hand." 3 Though our various evolved competences cannot be radically dissonant if the organism is to survive, neither are they logically integrated, neatly interlocking "modules." Under some environmental conditions, specific adaptations or epigenetic rules are not likely to produce a competitive advantage while other very different adaptations certainly will, and hence the flexibility of the organism ensures its survival. If, for instance, I place my coffee mug down on my desk and at that exact moment two cars collide on the street outside, familiarity with my environment militates against invocation of the causal rule, even though such a rule is incontrovertibly part of our adapted psychology. 4 Knowing, then, that we share an evolved psychic architecture whose patient excavation, so to speak, will result in a progressively better defined concept of human nature, and knowing too that the behavior of human beings as writers as well as other kinds of agents varies under divergent environmental conditions, Darwinian criticism should be sensitive to the complex relationship between individual adaptations, the total array of adaptations, subjective cognitive processes, and environmental circumstances that give literary works enduring significance. In contemplating literary meaning, as with aesthetics, we should be mindful that epigenesis is not simply the instantiation of epigenetic rules. 5 Ideally, literary interpretation should be informed by the evolution of mind, behavior, and...

This paper discusses the zombie argument and other antiphysicalist arguments presented by David Chalmers in his book, The Conscious Mind . It is argued that both premises of the zombie argument -- the conceivability of zombies and the conceivabilitypossibility thesis --cannot be made simultaneously plausible without additional argument in support of one of the premises. The best strategy for the proponent of the zombie argument is identified as limiting the conceivability-possibility thesis to an idealized notion of conceivability, and arguing separately (...) for the conceivability of zombies in this idealized sense. Out of Chalmers' main arguments, the argument from epistemic asymmetry and the argument from absence of analysis are considered in this role. It is argued that, while either of the arguments would, if sound, be appropriate for the role, the first is subject to decisive counter-arguments. The second, on the other hand, is found not only suitable to support the zombie argument, but also more convincing in that its premises are less controversial. Since the argument from absence of analysis also establishes the falsity of physicalism directly by itself, if sound, it can be seen to render the zombie argument redundant. (shrink)

Cambridge, MA: Harvard UP, 1996. [P] Trans. of Entferntes Verstehen: Studien zu Philosophie und Literatur von Kant bis Celan. Frankfurt am Main: Suhrkamp, 1998. [EV] 1. The Rest of Language When Aristotle, at the opening of his treatise on interpretation, defines the nature and function of language, he does so by referring "the things in the voice [ta en tei phonei]" to impressions on the soul (pathe¯mata), which, in turn, he refers to "things [pragmata]" [De interpretatione 16a4 ff.]. Aristotle's text establishes, in this way, that vocal utterances are signs of things. The philosophical significance of this gesture could not be more decisive. Once De interpretatione determines the canonical form of the statement as a "meaningful sentence [logos se¯mantikos]" and, more precisely, as a "proposition [logos apophantikos]" bearing truth or falsity, and once it asserts that truth and falsity reside in the composition (synthesis) of elements [16a10-15], 1 the consequence is inevitable: the paradigmatic form of true speech must be that of the "statement of one thing concerning another thing [legein ti kata tinos]" [17a25]. 2 Here it matters little whether the relation of speech to things is grasped as one of imitation or constitution, reproduction or production; it matters little, moreover, whether the things at issue--that which language means--are understood as sensible objects or supersensuous entities, material beings or logical idealities. In every utterance, speech, by virtue of its very form, is necessarily capable of being dissolved into those things of which it speaks. Indeed, the Aristotelian principle of analysis (literally, "loosening up") demands this [End Page 22] dissolution as the end toward which all speech, insofar as it is both assertive and predicative, ultimately tends. Language is thus posited only in order to be effaced; its specific constituents are identified only to be returned, in the end, to the world of things. When Augustine writes, in a lapidary formula at the start of his De doctrina christiana, that "things are learned by signs [res per signa discuntur]" [1.2.2.20], he simply summarizes what is already stated in the Aristotelian locus classicus: words, the elements of language, function in the service of things; when words show what exists, their task is accomplished.Werner Hamacher's works constitute perhaps the most powerful contemporary attempt to delineate and interrogate this aporetic structure, by which language, in its classical philosophical and theoretical elaboration, is simultaneously constructed and effaced, identified as such and destituted of all propriety. The implications of this structure, which are both logical and metaphysical, extend not only to the Aristotelian, but even to the most modern theories of language and its operation. "At the end of every semantic theory of language and its truth," Hamacher thus writes in Premises: Essays on Philosophy and Literature from Kant to Celan, "stands the aporetic verdict: language does not speak; it has nothing to say" [P 338; EV 325]. When language is determined by its "semantic and referential functions," we read, it follows that at "the end and thus the site of its destination, it no longer means anything and no longer refers to anything" [P 338; EV 325]. If Hamacher's texts often take as their point of departure contemporary doctrines of literary production and language, it is because, in the field of literary studies, the invocation of the semantic determination of language thus leads thought to eliminate the very element that might have been its subject of examination: language. The one discipline that might have resisted the apophantic dissolution of language proves itself not to be, as the German term has it, a "science of literature [Literaturwissenschaft]" but, rather, "more or less clandestinely a science against literature" [P...

This article expands on what Bernard Stiegler describes as “The Ordeal of Truth”. Through an evolutionary account of cognition and its exteriorization in human technology, I highlight a recurring tension in philosophy between the “as-if” nature of our models and representations, and the doubt that infects even our most stable understanding of the world. Truth is here associated to the process of metastabilization that characterizes the biological organism. The famous case of Clive Wearing’s severe amnesia, as well as the fictional (...) treatment of amnesia in Christopher Nolan’s Memento, are recalled to highlight the connection between truth and memory, and more importantly the contingent character of the formation of thoughts, and the desperate nature of the construction of truths, through the evolutionarily conditioned “subjective necessity” to link the before and the after, the cause and the effect. I show that this same ordeal is reflected in the philosophy of science in what is known as “pessimistic meta induction”, which I put into dialogue with the growing pessimism about knowledge in contemporary technological culture known as “post truth”. Finally, a possible way out of this pessimism is briefly sketched: a compromise such that, without recourse to objective truth, and in full acceptance of an always already biased relation to the world, future technologies might be designed to incrementally reduce our biases, through an intrinsic mapping of the relative falsity of our models, rather than through some idealized extrinsic relation to an unattainable noumenal real.

The idea of enlightenment entails liberty, equality, rationalism, secularism, and the connection between knowledge and human well being. In spite of the setbacks of revolutionary violence, political mass murder, and two world wars, the spread of enlightenment values has become the yardstick by which moral, political, and even scientific advances are measured. Indeed, most critiques of the enlightenment ideal point to failure in implementation rather than principle. By contrast, David Stove, in On Enlightenment, attacks the intellectual roots of enlightenment (...) thought, to define the limitations of its successes and the areas of its likely failures. Stove is not insensitive to the many valuable aspects of enlightenment thought. He champions the use of reason and rationality, and recognizes the falsity of religious claims as well as the importance of individual liberty. What he rejects is the enlightenment's uncritical optimism regarding social progress and its willingness to embrace revolutionary change. What evidence is there that the elimination of superstition will lead to happiness? Or that it is possible to accept Darwinism without Social Darwinism? Or that the enlightenment's liberal, rationalistic outlook will ever lead to the kind of social progress envisioned by its advocates. Despite their best intentions, social reformers who attempt to improve the world as a whole inevitably make things worse. He advocates a conservative "go slow" approach to change, pointing out that today's social structures are so large and complex that any widespread social reform will have innumerable unforeseen consequences. For example, the welfare state may diminish individual initiative, the use of pesticides may increase the food supply while polluting the water supply, the popularizing of university education may lead to a decline in academic standards. Since government has a virtual monopoly on large-scale change, it follows, in Stove's view, that its powers must be limited in order to prevent large-scale damage. Instead, he argues that reforms, when they are to be made at all, must be realistic, local, necessary and never coercive. Writing in the conservative tradition of Edmund Burke with the same passion for clarity and intellectual honesty as George Orwell, David Stove was one of the most precise, articulate, and insightful philosophers of his day. "Never just an academic, Stove was also a prominent, often crotchety, public intellectual of a conservative and, all too often, reactionary bent, many of whose views were extremist on any account, and his targets were many.... For Stove the important question about a belief is not whether it is extreme or mainstream, but whether it is true, or probable, or has sound evidentiary and/or rational credentials. In this he was surely right." -D. D. Todd, Philosophy in Review David Stove taught philosophy at the University of New South Wales and the University of Sydney. He is the author of Against the Idols of the Age and Scientific Irrationalism, both available from Transaction.

In lieu of an abstract, here is a brief excerpt of the content:Education and Feminist AestheticsGauguin and the ExoticJane Duran (bio)IntroductionMuch has been made of the way in which Gauguin came to characterize the differences that he saw between the French and Tahitian populations once he had embarked on the series of voyages for which he is now celebrated.1 Although there is evidence to support a number of interpretations with respect to his portrayals of women, one theme has been paramount (...) in a great deal of the commentary: Gauguin came to see the women of Tahiti as not only emblematic of the island itself, and the island's culture, but as the embodiments of a certain sort of feminine grace. The contrasts that Gauguin himself invoked between the "naturalness" of the Polynesian women and what he took to be the falsity of women of his own class in Europe, especially France, has been the subject of much writing. In our attempts to educate undergraduates with respect to categories of oppression, we can appeal to the work of Gauguin as a valuable source of understanding concerning these issues.Given the Eurocentrism of the time, and given that it is roughly this same time period that Said will later go on to associate with the rise of Orientalism, it is probably not possible that Tahiti, its women, and its various flora and fauna could have been seen as anything other than vestiges of the natural in a world already too tamed. Words such as "savage" are used frequently in the criticism of the day to explain Gauguin's subjects, and some of the themes of his work seem to have been chosen specifically because they lent themselves to such an interpretation, at least in European eyes.2 But Gauguin goes a bit further than this crude caricature indicates, at least insofar as his portraits of female figures are concerned. It is clear that, for the [End Page 88] artist, they represent all that is to him unknown about Tahiti, and that at the same time they are coded as the natural, the innocent, and even the holy. An examination of some of his works will bear out the extent to which this is the case.IRegarding Gauguin's attitudes toward Tahiti and its women, Britt Salvesen has noted in recent commentary thatGauguin infused his art with mystery, often by depicting enigmatic female figures, traditional symbols of nature and its secrets. In Tahiti he expected to encounter exotic and sensual women. Given Gauguin's complicated position as both observer and participant in Tahitian society, his ambition to represent the "country's female type" bears close examination. He owned illustrated travel books in which, as he noted scornfully, "all the [natives] … look like Minerva or Pallas Athena." He aimed to disrupt this conventional projection of European ideals and fantasies onto Tahitian women.3As Salvesen indicates, Gauguin expected to find, and did find—by his lights—"exotic" and "sensual" women. Feminist analysis has provided us with an overwhelming amount of material about the extent to which such projections onto women as a group become a near universal human cultural trope, but few individuals allow us to make such strong comparisons with respect to projections on differing female figures as Gauguin does. That he is able to discern the ridiculousness of Academy art with its emphasis on "Pallas Athena" is obvious; what he chooses to do himself is something else again.Inaugurating a variety of personal relationships with women and girls as young as thirteen years of age,4 Gauguin developed a view of the Tahitian woman as emblematic simultaneously of the culture, of a certain sort of innocence, and of a virtually transcendental sacredness. That these images might be thought, naively, to have little to do with sensuality reflects the degree to which we fail to understand that for Gauguin, as for others after him, the sensual itself was sacred. Salvesen notes that one of the early relationships was with the "thirteen-year-old Tehamana. … [o]f Polynesian origin, [in]experienced, and of a seemingly 'impenetrable' character, Tehamana offered Gauguin the mysterious experience he sought in life and art."5If Tehamana represents one take on woman-as-elementally...

This work contains ten essays published by Spaemann between 1965 and 1975, as well as an exchange between Spaemann and J. Habermas concerning one of the essays. Another of the essays, "Remarks on the Problem of Equality," is accessible in translation ; this essay embodies many of the themes discussed by Spaemann in the other pieces reprinted in the book. In the introduction written for the book, Spaemann summarizes the theme common to the essays: "It is always a question of (...) rational objections against the abstract utopia of radical-emancipatory rule of reason.... The thesis of this book is that this utopia is irrational". The irrationality consists both in the assumption that economic scarcity can be abolished and in the assumption that perfect social and individual rationality will be implemented at a future date, but is at present accessible only to the revolutionary vanguard which has appointed itself as the representative of the ideal. The fact that the majority of the populace does not consent to the revolutionaries’ ideal, much less tactics, is then perceived by the revolutionaries as proof that the majority is "immature" or "sick." Spaemann cannot be said to have demonstrated the falsity of the first assumption. The bulk of his essays is channeled into multiform attacks on the second assumption. Spaemann shows, to my mind successfully, that in practice the unrestrained passion for justice results, in a "dialectical" way, in injustice. In this context Spaemann criticizes liberation theology, as well as reliance on conscience as a basis for political action. In essence the same observation about the dangers of the passion for justice is made, as Spaemann knows well, by Plato’s Republic. The classical conception of restrained and tolerant rule in a regimen mixtum is superior to the fanaticism and totalitarianism which results from the passion just referred to. Spaemann finds the modern theoretical basis of the utopian "emancipation" doctrine articulated by Marx. (shrink)

Raimon Panikkar is one of the most sophisticated and most profound among contemporary pluralists of religion. His pluralism is radical because it is rooted in the very nature of things, in the pluralism of being itself, beyond all perspectivalism and indeed beyond truth and falsity taken as intellectual categories. I discuss several issues regarding his position. Is he indeed a pluralist or a monist in disguise? Does he do justice to the uniqueness of each religion? Is he not prematurely (...) introducing the eschatological ideal of the harmony of opposites into the historical world where opposites often produce bloody conflicts? (shrink)

_Material Falsity and Error in Descartes’s Meditations _approaches Descartes’s Meditations as an intellectual journey, wherein Descartes’s views develop and change as he makes new discoveries about self, God and matter. The first book to focus closely on Descartes’s notion of material falsity, it shows how Descartes’s account of material falsity – and correspondingly his account of crucial notions such as truth, falsehood and error – evolves according to the epistemic advances in the Meditations. It also offers important (...) new insights on the crucial role of Descartes’s Third Meditation discussion of material falsity in advancing many subsequent arguments in the Meditations. This book is essential reading for those working on Descartes and early modern philosophy. It presents an independent reading on issues of perennial interest, such as Descartes’s views on error, truth and falsehood. It also makes important contributions to topics that have been the focus of much recent scholarship, such as Descartes’s ethics and his theodicy. Those working on the interface between medieval and modern philosophy will find the discussions on Descartes’s debt to predecessors like Suárez and Augustine invaluable. (shrink)

Although there is a massive amount of work on truth, there is very little work on falsity. Most philosophers probably think this is appropriate; after all, once we have a solid understanding of truth, falsity should not prove to be much of a challenge. However, there are several interesting and difficult issues associated with understanding falsity. After considering two prominent definitions of falsity and presenting objections to each one, I propose a definition that avoids their problems.

This paper synthesizes convergent lines of evidence to evaluate the hypothesis that objective falsity is essential to lying. Objective accounts of lying affirm this hypothesis; subjective accounts deny it. Evidence from history, logic, social observation, popular culture, lexicography, developmental psychology, inference, spontaneous description, and behavioral experimentation strongly supports the hypothesis. Studies show that the only apparent evidence against the hypothesis is due to task substitution, i.e. ethical concerns or perspective-taking interfering with performance on categorization tasks. I conclude that, overall, (...) existing evidence decisively favors objective accounts. (shrink)

This book argues that the meaning of negation, perhaps the most important logical constant, cannot be defined within the framework of the most comprehensive theory of proof-theoretic semantics, as formulated in the influential work of Michael Dummett and Dag Prawitz. Nils Kürbis examines three approaches that have attempted to solve the problem - defining negation in terms of metaphysical incompatibility; treating negation as an undefinable primitive; and defining negation in terms of a speech act of denial - and concludes that (...) they cannot adequately do so. He argues that whereas proof-theoretic semantics usually only appeals to a notion of truth, it also needs to appeal to a notion of falsity, and proposes a system of natural deduction in which both are incorporated. Offering new perspectives on negation, denial and falsity, his book will be important for readers working on logic, metaphysics and the philosophy of language. (shrink)

We give a procedure to obtain falsity conditions for IF-sentences, using Skolemization. The expressive power of an IF-sentence can then be strongly captured by a pair of Σ11-sentences. A result from [Burgess 2003] shows that, conversely, any pair of incompatible Σ11-sentences corresponds with an IF-sentence.In the second part, we reflect on the influence of the order of the steps (inside-out versus outside-in) in the Skolemization procedures for IF-logic. We also reflect on the nature of game theoretical negation.
