In the typical single-stimulus perceptual identification task, accuracy is improved by prior study of test words, a repetition priming benefit. There is also a cost, inasmuch as previously studied words are likely to be produced as responses if the test word is orthographically similar but not identical to a studied word. In two-alternative forced-choice perceptual identification, a test word is flashed and followed by two alternatives, one of which is the correct response. When the two alternatives are orthographically similar, test (...) words identical to previously studied items are identified more accurately than new words but tests words orthographically similar to studied words are identified less accurately than new words . Ratcliff and McKoon argue that these are bias effects that arise in the decision stage of word identification. We report five experiments that examined the alternative hypothesis that these bias effects arise from postperceptual guessing strategies. In single-stimulus perceptual identification, repetition priming benefits were equally great for young and older adults who claimed to use deliberate guessing strategies and those who did not . In contrast, only groups of young and older people who claimed to deliberately guess studied words in a two-alternative forced-choice task showed reliable benefits and costs. Costs and benefits were abolished in the two-alternative forced-choice task when a very long study list was used, presumably because the increased retrieval burden made the use of deliberate guessing strategies less attractive . Under conditions similar to those of Experiment 3, repetition priming was observed in single-stimulus perceptual identification . These results are consistent with the view that costs and benefits in the forced-choice perceptual identification task arise from deliberate guessing strategies but that those in the single-stimulus task do not. The possibility that the observed relationship between strategy reports and priming effects reflects erroneous postexperimental assessments of strategies by participants is also considered. (shrink)

The collection of papers that comprise this thesis explore three sets of questions important to environmental philosophy, broadly construed. All three topics are explored through the theoretical device of environmental pragmatism, the argument that philosophical disagreements on environmental questions can sometimes be set aside in order to achieve compatible strategies to work toward improving environmental conditions. As part of this strategy, pragmatists also call for the abandonment of the existing prejudices of environmental philosophy, in particular nonanthropocentrism and commitments to (...) moral monism. Part I of the thesis looks at two sets of debates in environmental philosophy: the social ecology-deep ecology divide in political ecology, and the debate between monists and pluralists in environmental ethics. Both debates are used as a vehicle to advance the pragmatist position, as well as demonstrate the connection between this thesis and other attempts to articulate a workable form of pluralism in environmental philosophy. Next, the first half of Part II uses the pragmatist premise to launch applied investigations of two environmental questions: the privatization of environmental regulations, and the political appropriation of restoration ecology. The second half of Part II explores questions concerning urban space and political identity, which come to the center of environmental philosophy following a pragmatist assault on its existing prejudices. Finally, Part III continues the themes of the last half of Part II to look at issues concerning technology and built space, topics which have traditionally been ignored by environmental philosophers. These final chapters present a set of issues concerning space and place which must be integral to an environmental philosophy which has been tempered by pragmatic concerns. (shrink)

Robert Elliot's "Faking Nature," represents one of the strongest philosophical rejections of the ground of restoration ecology ever offered. Here, and in a succession of papers defending the original essay, Elliot argued that ecological restoration was akin to art forgery. Just as a copied art work could not reproduce the value of the original, restored nature could not reproduce the value of nature. I reject Elliot's art forgery analogy, and argue that his paper provides grounds for distinguishing between two forms (...) of restoration that must be given separate normative consideration: malicious restorations, those undertaken as a means of justifying harm to nature, and benevolent restorations, or, those which are akin to art restorations and which cannot serve as justifications for the conditions which would warrant their engagement. This argument will require an investigation of Mark Sagoff's arguments concerning the normative status of art restorations. (shrink)

RÉSUMÉ Oublier Baudrillard? Pourquoi devrions-nous oublier un art qui, malgré sa remarquable sérénité et même sa nonchalance ostensible, s'acharne à nous dire quelque chose sur notre condition, un art qui ne craint ni d'investiguer, ni de raconter les terribles paradoxes de l'existence contemporaine et de la civilisation contemporaine, un art qui, aussi rare que cela puisse être, peut engendrer le paradoxe? ABSTRACT A respected commentator on contemporary French intellectual life, tells us that we should, perhaps, "forget Baudrillard" But why should (...) we forget such a subtle art as Baudrillard's? Why should we forget an art wich, for all its remarkable serenity and, even, ostensible nonchalance, remains impassioned to tell us something about our condition, an art fearing neither to investigate nor to narrate the terrible paradoxes of contemporary existence and contemporary civilization, indeed, an art wich, rare as this is, can bear paradox?

We explore ways in which purely qualitative belief change in the AGM tradition throws light on options in the treatment of conditional probability. First, by helping see why it can be useful to go beyond the ratio rule defining conditional from one-place probability. Second, by clarifying what is at stake in different ways of doing that. Third, by suggesting novel forms of conditional probability corresponding to familiar variants of qualitative belief change, and conversely. Likewise, we explain how recent work on (...) the qualitative part of probabilistic inference leads to a very broad class of 'proto-probability' functions. (shrink)

Excerpt from Conditions of National Success Not the centre of the universe, must on moral grounds be made the centre of any investigation into his position in that universe. Indeed, the idea Of society dominating the individual is SO Offensive to some people that the very term social organism arouses in them a strong antipathy. Societies exist because individuals have found them useful. Further more, since societies are thus a mere matter of individual arrangement it is advisable on scientific (...) as well as on moral grounds that our attention should be concentrated upon the individual. Society and the state are supposed to be without meaning except in SO far as they help the individual and increase the fullness of individual life, and study of the individual is under these circumstances much better calculated to throw a light upon the nature of society than the study of society upon the nature of the individual.

Suppositional theories of conditionals take apparent similarities between supposition and conditionals as a starting point, appealing to features of the former to provide an account of the latter. This paper develops a novel form of suppositional theory, one which characterizes the relationship at the level of semantics rather than at the level of speech acts. In the course of doing so, it considers a range of novel data which shed additional light on how conditionals and supposition interact.

In this paper I suggest an account of knowledge by adding a fourth condition to the traditional analysis in terms of justified true belief. I am going to make a first proposal ruling out the Gettier-counterexamples.1 This proposal will then be corrected in the light of other counterexamples. The final analysis will be a combination of a justified-true-belief-account and a causal account of knowledge. Some philosophers have disputed that Gettier‟s examples must be accepted as refutations of the justified true belief (...) analysis of knowledge.2 Their rejection rests on declining a principle underlying Gettier‟s reasoning, namely – as Thalberg calls it – the principle of deducibility of justification (PDJ). PDJ reads as following: For any proposition p, if a person S is justified in believing p, and p entails q, and S deduces q from p and accepts q as a result of this deduction, then S is justified in believing q. This principle allows, for example, the move in Gettier‟s first example from the proposition a) “Jones is the man who will get the job and Jones has ten coins in his pocket” to proposition b) “The man who will get the job has ten coins in his pocket”. 1.

Religions, ideologies try to give a complete vision of the world a vision containing both its origin, explanation and a “normative kit”: a collection of precepts and rules, which should regulate human activities and behavior. Their synergetic meaning is clear: if embraced by all they allow for development of strong synergetic effects on the social macro scales. These in turn may lead to creation of order and beauty, of intellectual, spiritual and moral development within men and in society. In this (...) consist the elements of their natural—i.e. not explicitly reasoned out—wisdom. However, as they contain also some elements of harmful consequences—at least if they are literally accepted and in a fundamentalist manner practiced—they cannot be universally accepted. But—rejecting them we lose also the important sourcesof natural—or should we say instinctive—wisdom.Could the solution of this contradiction, of this one of the basic human sources of suffering be looked for in the modern science of complexity?Synergetics and the sciences of complex systems in general offer a solid scientific base for a meta-philosophical, universalist intellectual framework. Its offspring the social synergetics offers concrete propositions of optimized social structures. Optimized in the sense of espousing the main synergetic effects with being at the same time free of the negative “side effects” happening when religions or ideologies are the source of synergism.Finally a connection is discussed between the presented ideas and the concept of “love of wisdom”. The term “love of wisdom” may be understood as striving not only to possess a “sound and serene judgment regarding the conduct of life” but also a practical ability to act according to that judgment.This ability may be also expressed using the information-thermodynamic concepts of synergetics. Indeed without the ever continuing negentropy transformation neither survival of a complex system like man or society nor its continuing development—uncovering of all his “hidden potentials” is possible.To assure maximization of this transformation process creation of strong synergetic effects—of reinforcement, of positive feedback—between all human beings—i.e. not excluding any nations, any social groups, and any individuals—are necessary. Acting towards local and global realization of such a structure everywhere on our planet constitutes the essence of social wisdom.Removing all obstacles towards this goal—obstacles existing on the intellectual, emotional and spiritual level—should be one of the most important tasks of various institutions, of state structures, of purified from mythical elements ideologies, of man oriented sciences and above all of the modern universalism.Thus striving towards its realization is an expression of the love of wisdom. Of wisdom once based on the elements of mythos and now regained in the full light of Logos. (shrink)

Many translations have been made from the original Sanskrit of the Yoga Sutras of Patanjali. They have become well loved, well used, and well applied by many in all parts of the world and of all religious beliefs. The Sutras have a power and a timelessness about them which demonstrate the accuracy with which they pinpoint the basic truths of human evolution from subservience to personality clamours to the serene freedom of the soul. Most human problems today originate in selfish (...) desire; the prostitution of the feeling nature to self-centred physical appetites. This is also brought out clearly in the teaching of the Lord Buddha, the treading of the Noble Eight-Fold path providing the only way out of the maze: Right Values; Right Speech; Right Mode of Living; Right Thinking; Right Expression; Right Conduct; Right Effort; Right Rapture or True Happiness. These are attributes of the soul. Patanjali explores exhaustively the means, the techniques and the mental posture which create the connecting thread between the form-centred personality and these stages towards spiritual achievement and soul fusion. The four parts of the book develop: 1. The Problem of Union (51 sutras). 2. sutras). 4. Illumination (34 sutras). Many different training techniques have been available over the centuries, depending on the condition of human consciousness and the phase of spiritual growth to be accomplished. Each Yoga has had its place, fulfilled its function, and become an absorbed part of human experience. In this book the factor of mind in meeting present-day needs is again given prominence as the agent of the soul, and the key to personality release. These Yoga Sutras of Patanjali are based on Raja Yoga, the kingly science of the soul: Through the science of Raja Yoga the mind will be known as the instrument of the soul and the means whereby the brain of the aspirant becomes illuminated and knowledge gained of those matters which concern the realm of the soul. The soul is concerned with the working out of planetary purpose and plan; so again we find that mental training, and the self-achievement of the individual, lead to cooperation and service on a scale far more comprehensive and of far greater evolutionary significance than merely the individual effects on the life of the disciple. venture on the path of union with the soul. When through the removal of hindrances and the purification of the sheaths, the totality of knowledge becomes available, naught further remains for the man to do. (shrink)

In this paper, I will discuss the various ways in which intentions can be said to be conditional, with particular attention to the internal conditions on the intentions’ content. I will first consider what it takes to carry out a conditional intention. I will then discuss how the distinctive norms of intention apply to conditional intentions and whether conditional intentions are a weaker sort of commitments than the unconditional ones. This discussion will lead to the idea of what I (...) call the ‘deep structure’ of intentions. Roughly, this is the idea that the conditional nature of our intentions is only partially made explicit in the expressions we use to communicate our intentions and in the explicit form of our thinking about and reasoning with them. Most conditions that qualify our intentions are part of a deep functional structure that can be evinced by observing the actual psychological functioning of intentions and by considering the rational requirements that they engage. I will argue that the deep structure of intentions is characteristically conditional. Genuinely unconditional intentions are only limiting instances of conditional intentions and their contribution to agency can only be understood in light of this fact. I will conclude by showing that the characteristic conditional structure of intentions is intimately related to distinctive features of human agency, especially to its unity over time. (shrink)

Jonathan Weisberg has argued that Jeffrey Conditioning is inherently “anti-holistic” By this he means, inter alia, that JC does not allow us to take proper account of after-the-fact defeaters for our beliefs. His central example concerns the discovery that the lighting in a room is red-tinted and the relationship of that discovery to the belief that a jelly bean in the room is red. Weisberg’s argument that the rigidity required for JC blocks the defeating role of the red-tinted light (...) rests on the strong assumption that all posteriors within the distribution in this example are rigid on a partition over the proposition that the jelly bean is actually red. But individual JC updates of propositions do not require such a broad rigidity assumption. Jeffrey conditionalizers should consider the advantages of a modest project of targeted updating focused on particular propositions rather than seeking to update the entire distribution using one obvious partition. Although Weisberg’s example fails to show JC to be irrelevant or useless, other problems he raises for JC (the commutativity and inputs problems) remain and actually become more pressing when we recognize the important role of background information.

Scoring rules measure the deviation between a forecast, which assigns degrees of confidence to various events, and reality. Strictly proper scoring rules have the property that for any forecast, the mathematical expectation of the score of a forecast p by the lights of p is strictly better than the mathematical expectation of any other forecast q by the lights of p. Forecasts need not satisfy the axioms of the probability calculus, but Predd et al. [9] have shown that given a (...) finite sample space and any strictly proper additive and continuous scoring rule, the score for any forecast that does not satisfy the axioms of probability is strictly dominated by the score for some probabilistically consistent forecast. Recently, this result has been extended to non-additive continuous scoring rules. In this paper, a condition weaker than continuity is given that suffices for the result, and the condition is proved to be optimal. (shrink)

In the name of efficiency, the practice of education has come to be dominated by neoliberal ideology and procedures of standardization and quantification. Such attempts to make all aspects of practice transparent and subject to systematic accounting lack sensitivity to the invisible and the silent, to something in the human condition that cannot readily be expressed in an either-or form. Seeking alternatives to such trends, Saito reads Dewey’s idea of progressive education through the lens of Emersonian moral perfectionism (to borrow (...) a term coined by Stanley Cavell). She elucidates a spiritual and aesthetic dimension to Dewey’s notion of growth, one considerably richer than what Dewey alone presents in his typically scientific terminology. (shrink)

It is still perhaps not widely appreciated that in 1905 Einstein used his postulate concerning the ‘constancy’ of the light-speed in the ‘resting’ frame, in conjunction with the principle of relativity, to derive numerical light-speed invariance. Now a ‘weak’ version of the relativity principle (or, alternatively, appeal to the Michelson—Morley experiment) leads from Einstein's light postulate to a condition that we call universal light-speed constancy. which is weaker than light-speed invariance. It follows from earlier independent investigations (Robertson [1949]; Steigler [1952]; (...) Tzanakis and Kyritsis [1984]) that this condition is none the less sufficient to derive the Lorentz transformations up to a scale factor, given the well-known kinematic principle of ‘reciprocity’. In this paper, we follow Robertson and explore the kinematics consistent with universal light-speed constancy without imposing reciprocity, and we recover the Lorentz transformations by further appeal only to the weak relativity principle and spatial isotropy.

Finally, I formulate a simple semantics for the subjunctive conditional that is consistent with both (...) CXM and Tooley's counterexample. (shrink)

Conditional logics were originally developed for the purpose of modeling intuitively correct modes of reasoning involving conditional—especially counterfactual—expressions in natural language. While the debate over the logic of conditionals is as old as propositional logic, it was the development of worlds semantics for modal logic in the past century that catalyzed the rapid maturation of the field. Moreover, like modal logic, conditional logic has subsequently found a wide array of uses, from the traditional (e.g. counterfactuals) to the exotic (e.g. conditional (...) obligation). Despite the close connections between conditional and modal logic, both the technical development and philosophical exploitation of the latter has outstripped that of the former, with the result that noticeable lacunae exist in the literature on conditional logic. My dissertation addresses a number of these underdeveloped frontiers, producing new technical insights and philosophical applications. -/- I contribute to the solution of a problem posed by Priest of finding sound and complete labeled tableaux for systems of conditional logic from Lewis' V-family. To develop these tableaux, I draw on previous work on labeled tableaux for modal and conditional logic; errors and shortcomings in recent work on this problem are identified and corrected. While modal logic has by now been thoroughly studied in non-classical contexts, e.g. intuitionistic and relevant logic, the literature on conditional logic is still overwhelmingly classical. Another contribution of my dissertation is a thorough analysis of intuitionistic conditional logic, in which I utilize both algebraic and worlds semantics, and investigate how several novel embedding results might shed light on the philosophical interpretation of both intuitionistic logic and conditional logic extensions thereof. -/- My dissertation examines deontic and connexive conditional logic as well as the underappreciated history of connexive notions in the analysis of conditional obligation. The possibility of interpreting deontic modal logics in such systems (via embedding results) serves as an important theoretical guide. A philosophically motivated proscription on impossible obligations is shown to correspond to, and justify, certain (weak) connexive theses. Finally, I contribute to the intensifying debate over counterpossibles, counterfactuals with impossible antecedents, and take—in contrast to Lewis and Williamson—a non-vacuous line. Thus, in my view, a counterpossible like "If there had been a counterexample to the law of the excluded middle, Brouwer would not have been vindicated" is false, not (vacuously) true, although it has an impossible antecedent. I exploit impossible (non-normal) worlds—originally developed to model non-normal modal logics—to provide non-vacuous semantics for counterpossibles. I buttress the case for non-vacuous semantics by making recourse to both novel technical results and theoretical considerations. (shrink)

The probabilities a Bayesian agent assigns to a set of events typically change with time, for instance when the agent updates them in the light of new data. In this paper we address the question of how an agent's probabilities at different times are constrained by Dutch-book coherence. We review and attempt to clarify the argument that, although an agent is not forced by coherence to use the usual Bayesian conditioning rule to update his probabilities, coherence does require the agent's (...) probabilities to satisfy van Fraassen's [1984] reflection principle (which entails a related constraint pointed out by Goldstein [1983]). We then exhibit the specialized assumption needed to recover Bayesian conditioning from an analogous reflection-style consideration. Bringing the argument to the context of quantum measurement theory, we show that "quantum decoherence" can be understood in purely personalist terms---quantum decoherence (as supposed in a von Neumann chain) is not a physical process at all, but an application of the reflection principle. From this point of view, the decoherence theory of Zeh, Zurek, and others as a story of quantum measurement has the plot turned exactly backward. (shrink)

In this paper, we propose a unified account of conditionals inspired by Frank Ramsey. Most contemporary philosophers agree that Ramsey’s account applies to indicative conditionals only. We observe against this orthodoxy that his account covers subjunctive conditionals as well—including counterfactuals. In light of this observation, we argue that Ramsey’s account of conditionals resembles Robert Stalnaker’s possible worlds semantics supplemented by a model of belief. The resemblance suggests to reinterpret the notion of conditional degree of belief in order to overcome a (...) tension in Ramsey’s account. The result of the reinterpretation is a tenable account of conditionals that covers indicative and subjunctive as well as qualitative and probabilistic conditionals. (shrink)

The idea of multiple options for action in a specific situation is essential for choice and deliberation. But what exactly is an option for action? A simple and natural approach to this question is via conditional analyses.

Others do, but the analyses can be modified or interpreted in a suitable way so as to deal with (...) them. One central difficulty, however, remains and can only partially be resolved. Still, all things considered, the prospects of conditional analyses of options for action are quite good; they should not be lightly dismissed. (shrink)

At the center of the literature on conditionals lies the division between indicative and subjunctive conditionals, and Ernest Adams’ famous minimal pair: If Oswald didn’t shoot Kennedy, someone else did. If Oswald hadn’t shot Kennedy, someone else would have. While a lot of attention is paid to figuring out what these different kinds of conditionals mean, significantly less attention has been paid to the question of why their grammatical differences give rise to their semantic differences. In this paper, I articulate (...) and defend an answer to this question that illuminates and unifies the meanings of both kinds of conditionals. The basic idea is that epistemic and metaphysical possibilities differ with respect to their interaction with time, such that there can be present epistemic possibilities with different pasts, while present metaphysical possibilities share the same past. The interpretation of conditionals is subject to a pragmatic constraint that rules out interpretations in which their consequents are directly settled by information used to build their domains. The past + future morphology on subjunctives, but not indicatives, is what allows them to receive a metaphysical interpretation in light of this pragmatic constraint. The resulting theory predicts several surprising features of indicatives and subjunctives, which I argue are correct. (shrink)

This paper reviews the psychological investigation of reasoning with conditionals, putting an emphasis on recent work. In the first part, a few methodological remarks are presented.

Arguments and conditionals are powerful means language provides us to reason about possibilities and to reach conclusions from premises. These two kinds of constructions exhibit several affinities—e.g., they both come in different varieties depending on the mood; they share some of the same connectives (i.e., ‘then’); they allow for similar patterns of modal subordination. In the light of these affinities, it is not surprising that prominent theories of conditionals—old and new suppositionalisms as well as dynamic theories of conditionals—as well as (...) certain reductive theories of arguments tend to semantically assimilate conditionals and arguments. In this paper, I shall marshall some linguistic evidence as well as some theoretical considerations for thinking that, despite these similarities, arguments and conditionals should be given a different semantics and I shall lay out a framework that can capture at least some of their affinities while accounting for their outstanding differences.

Much work in the philosophy of action in the last few decades has focused on the elucidation and justification of a series of purported norms of practical rationality that concern the presence or absence of intention in light of belief, and that demand a kind of structural coherence in the psychology of an agent. Examples of such norms include: Intention Detachment, which proscribes intending to do something in case some condition obtains, believing that such condition obtains, and not intending to (...) do that thing; Intention-Belief Consistency, which proscribes intending to do what you believe you will not do; Intention Consistency, which proscribes intending each of two ends you believe to be inconsistent; and Means-End Coherence, which proscribes intending an end and not intending the means you believe to be implied by your end. In this paper, I present a series of examples that show that these requirements are not genuine requirements of rationality. The reason for this is simple: these requirements concern the presence or absence of intention in light of all-out belief. Rational agents like us, however, do not, and in fact should not, always form or revise their intentions in light of what they all-out believe. When such agents do not form or revise their intentions in light of what they all-out believe, they need not be irrational if they do not conform to these requirements. (shrink)

This article analyses the work of the twentieth-century late modernist Samuel Beckett, in light of the turn-of-the-century anti-rationalist Henri Bergson and the eighteenth-century neoclassicist Samuel Johnson. What unites these three very different thinkers is a concern over habitual, automatic and involuntary behavior, which in all three cases has a distinctly neurological dimension. Beckett’s writing explores the Bergsonian notion, informed by medicine and experimental psychology, of the limitations of agency, of “the deep-seated recalcitrance of matter,” and of the human as always (...) already inflicted by the mechanical, a fact that is poignantly highlighted by the case of Samuel Johnson. Through his encounter with Johnson, Beckett registers a paradigm shift in the understanding of subjectivity. Whereas Bergson aims, throughout his career, to contest the mechanical, habitual and automatic that threaten to encrust themselves upon the living, in Beckett’s often uncannily Johnsonian writing, the habitual and the automatic become progressively more central, until in the late works, habit and mechanical behavior constitute a tenuous, fraught and primitive ontology, the residues of an agential self.

Our understanding of subjunctive conditionals has been greatly enhanced through the use of possible world semantics and, more precisely, by the idea that they involve variably strict quantification over possible worlds. I propose to extend this treatment to ceteris paribus conditionals – that is, conditionals that incorporate a ceteris paribus or ‘other things being equal’ clause. Although such conditionals are commonly invoked in scientific theorising, they traditionally arouse suspicion and apprehensiveness amongst philosophers. By treating ceteris paribus conditionals as a species (...) of variably strict conditional I hope to shed new light upon their content and their logic. (shrink)
