While thrusting the importance of knowledge, Bertrand Russell highlights one special utility of it, i.e., knowledge promotes a widely contemplative habit of mind; and such knowledge, he terms ‘useless’. For Russell, the habit of contemplation is the capacity of rationalized enquiry which enables individuals to consider all questions in a tentative and impartial manner, frees them from dogmas and encourages the expression of a wide diversity of views. Besides ‘useless’ knowledge, Russell admits the importance of ‘useful’ knowledge too, but his (...) appreciation for the intrinsic value of ‘useless’ knowledge more than the extrinsic value of ‘useful’ one brings to light the significance of knowing, i.e., to know is to know something for its own sake. Pursuit of such knowledge is possible only in case of ‘useless’ knowledge; and not in case of ‘useful’ one. Highlighting contemplative habit of mind as the greatest advantage of ‘useless’ knowledge, Russell says that such habit, in order to get accelerated, has to be guided by education; but education without freedom cannot perform the job. To be free, according to Russell, means, to be free from the forces of tradition; and also from the tyranny of one’s own passions. Freedom is thus seen to be the cardinal force in fostering contemplative habit, and is closely found to have been associated with ‘useless’ knowledge. In the present paper, by highlighting the nature of contemplative habit of mind, I have argued that ‘useless’ knowledge has to be appreciated more than ‘useful’ knowledge. Moreover, I have shown why freedom in education has to be considered a necessity for accelerating habit of contemplation. (shrink)

Sometimes we remember past objects or events in a vivid, experiential way. The present paper addresses some fundamental questions about the metaphysics of such experiential or ‘recollective’ memories. More specifically, it develops the ‘Relational Account’ of recollective memory, which consists of the following three claims. A subject who recollectively remembers a past object or event stands in an experiential relation to the relevant past object or event. The R‐remembered object or event itself is a part of the R‐memory; that is, (...) the subject's present R‐memory is partly constituted by the relevant past object or event. When a subject R‐remembers a past object, the past object is a constitutive part of the conscious experience itself; that is, the object is immediately available to the subject in conscious experience. In developing the Relational Account, the present paper hopes to make a substantial contribution to any attempt to account for the nature of recollective memory. Furthermore, in order to explain how a subject could understand the beliefs that she forms about the past on the basis of an R‐memory, and how a subject could, on the basis of an R‐memory, gain any knowledge about the past, we arguably also need to rely on the Relational Account of recollective memory. Thus, the Relational Account will also play an important role in an attempt to account for various other ways in which a subject might be related to the past in general, and to her own past in particular. Standing in such relations to the past is, in turn, a central feature of our human existence. Ultimately, therefore, the Relational Account of recollective memory should also play a crucial role in furthering our understanding of ourselves, and of our own existence in time. (shrink)

This article returns to the question of the foundations of Western culture. Many have trod this path before, notably Nietzsche. At issue is a theory of culture, and the classical Greek preoccupation with how humans can make sense of their lives, find direction and some sort of vindication — for that is what culture is, and does. Travelling Greece today, what surprises is the vitality of the ancient sites. Alive with their own cast of timeless enchantment, it is as if (...) they haven't changed over the millennia. Has this miraculous, enduring vitality something to do with the fact that the Western tree that Greece seeded continues to flourish? Or, is this just romantic illusion, a way to redeem the prosaic orders of modern everyday life; or, a fantasy aesthetico-religious culture to populate the disenchanted ruins of the Christian churchyard?

I set out two theses. The first is Lynn Robertson’s: (a) spatial awareness is a cause of object perception. A natural counterpoint is: (b) spatial awareness is a cause of your ability to make accurate verbal reports about a perceived object. Zenon Pylyshyn has criticized both. I argue that nonetheless, the burden of the evidence supports both (a) and (b). Finally, I argue conscious visual perception of an object has a different causal role to both: (i) non-conscious perception of the (...) object, and (ii) experience, e.g. hallucination, that may be subjectively indiscriminable from, but is not, perception of the object.

Although “theory” has been the prevalent unit of analysis in the meta-study of science throughout most of the twentieth century, the concept remains elusive. I further explore the leitmotiv of several authors in this issue: that we should deal with theorizing (rather than theory) in biology as a cognitive activity that is to be investigated naturalistically. I first contrast how philosophers and biologists have tended to think about theory in the last century or so, and consider recent calls to upgrade (...) the role of theory in the life sciences against the background of the recent “data deluge” in molecular biology, systems biology, etc. I then review thinking about theory in biology in relation to physical theory as a positive or negative exemplar. I conclude by discussing various aspects of a positive program for “naturalizing theorizing.”. (shrink)

The work of Henri Bergson has gone almost completely unnoticed in philosophy of sport literature. This in no way indicates the level of relevance his programme may carry for the subject. Many of the entrenched debates that have historically helped to shape the field are mirrored by Bergson's own concerns regarding perception and skill acquisition. As such, a thorough study of how the Bergsonian programme might approach the topic of athletic action is in no wise an idle pursuit? in fact, (...) very much the opposite. My intention in this paper is twofold: first, to indicate the natural commerce that exists between Bergson's philosophy and the philosophy of sport; second, and perhaps more ambitiously, to demonstrate that his approach to perception and action not only anticipates, but in some cases may help to edify, certain unresolved issues within the field. The paper develops in three parts. In part I, I provide a brief summary of Bergson's theory of perception as it is developed in Matter and Memory. Parts II and III will apply that theory to two of the central aspects of human motor activity: in part II, I investigate what it is to be in possession of skilled motor behaviour? to make that behaviour?automatic?, as it were; in part III, the controversial subject of what it is to acquire and modify skilled motor behaviour will be examined.

The arrow paradox is an argument purported to show that objects do not really move. The two main metaphysics of motion, the At–At theory of motion and velocity primitivism, solve the paradox differently. It is argued that neither solution is completely satisfactory. In particular it is contended that there are no decisive arguments in favor of the claim that velocity as it is constructed in the At–At theory is a truly instantaneous property, which is a crucial assumption to solve the (...) paradox. If so the At–At theory faces the threat that most of our physical theories turn out to be non-Markovian. Finally it is considered whether all those threats and paradoxes are dispelled if only a new metaphysics of persistence is taken into account, namely four-dimensionalism. (shrink)

Robert Aumann argues that common knowledge of rationality implies backward induction in finite games of perfect information. I have argued that it does not. A literature now exists in which various formal arguments are offered in support of both positions. This paper argues that Aumann's claim can be justified if knowledge is suitably reinterpreted.

The ArgumentEinstein's concept of causality as analyzed in this paper is a thick concept comprised of: (a) regularity; (b) locality; (c) symmetry considerations leading to conservation laws; (d) mutuality of causal interaction. The main theses are: 1. Since (b)–(d) are not elements of Hume's concept of causality, Einstein's concept, the concept embedded in the theory of relativity, is manifestly non–Humean. 2. On a Humean conception, Newtonian mechanics is a paradigmatically causal theory. Einstein, however, regarded this theory as causally deficient, for (...) it fails to comply with both (b) and (d). Special relativity was (partly) motivated by the wish to correct the first of these failures; general relativity the second. 3. Ironically, general relativity, based on the thick concept of causality, opens the way for a conventionalist understanding of that concept. 4. With regard to human freedom, Einstein professed to be a Spinozist. However, he suggested a version of soft determinism, not found in Spinoza. (shrink)

Neutral monism is a position in metaphysics defended by Mach, James, and Russell in the early twentieth century. It holds that minds and physical objects are essentially two different orderings of the same underlying neutral elements of nature. This paper sets out some of the central concepts, theses and the historical background of ideas that inform this doctrine of elements. The discussion begins with the classic neutral monism of Mach, James, and Russell in the first part of the paper, then (...) considers recent neo-Russellian versions in the second half. The chances for a revival of neutral monism are probably slight; its key ideas and starting points lie far from those in contemporary philosophy of mind. A better route might be through the philosophy of science and a deeper understanding of causation. (shrink)

Two eight-century Jaina contemporaries, a Śvetāmbara philosopher Siddhasena Mahāmati and a Digambara Akalaṅka Bhaṭṭa revolutionised Jaina epistemology, by radically transforming basic epistemological concepts, which had been based on canonical tradition. The paper presents a brief historical outline of the developments of basic epistemological concepts in Jaina philolosophy such as the cognitive criterion and logical faculties as well as their fourteen typological models which serve as the backdrop of important innovations in epistemology introduced by Siddhasena, Pātrasvāmin and Akalaṅka. An important contribution (...) of these Jaina thinkers was to economize Indian logic and the rules of inference, first, by devising only one kind of logical reason called ‘inexplicability otherwise’, based on the single inseparable connection of the proving property with the inferable property, and, second, by limiting the necessary number of the members of the proof formula merely to two. These two innovations were related to the thinkers’ intention to devise a logic which would not primarily be based on empirical verification but its structural patterns would be valid irrespective of external observation. Further, the paper focuses on the nature of the epistemological shifts which Siddhasena and Akalaṅka introduced independently of each other and on the question how Siddhasena’s and Akalaṅka’s ideas were partly anchored in Buddhist concepts of the pramāṇa school of Diṅnāga and Dharmakīrti. With the Buddhist background, Siddhasena sought to define the criteria essential to distinguish true from false cognitions and to provide a novel classification of the pramāṇas. He can further be accredited with formulating the first Jaina descriptive definition of the cognitive criterion. The final section of the paper explains how Akalaṅka applies novel epistemological ideas, first, to construct realistic ontology and objectivity of both the external world and the cognising subject, and, secondly, to combat fundamental Buddhist concepts such as idealism and momentariness.

The article is concerned with the practicalist attempt to "solve" the problem of induction. The point of departure is the concept of counter-induction introduced by Max Black and his refutation of practicalism. If we are not to beg the question whether induction yields knowledge of the future, Max Black asserts, there is a symmetry between induction and counter-induction as methods. The main point of the article is to show that this assertion is false, at least when induction and counter-induction are (...) compared as regards their relations to hypothetico-deductive method. As regards these relations, there is a striking asymmetry. The author tries to establish the following conclusion: A theory can agree with all future data and yet be false because it does not agree with all past data. If we are not to be in a position where our theories are necessarily falsified either by past or future data, we must use induction rather than counter-induction. (shrink)

The classical response to Zeno’s paradoxes goes like this: ‘Motion cannot properly be defined within an instant. Only over a period’ (Vlastos.) I show that this ob-jection is exactly what it takes for Zeno to be right. If motion cannot be defined at an instant, even though the object is always moving at that instant, motion cannot be defined at all, for any longer period of time identical in content to that instant. The nonclassical response introduces discontinuity, to evade the (...) paradox of infinite proximity of any point of a distance with any ‘next’. But it introduces the wrong sort of discontinuity because, rather than assuming the discontinuity of motion, as Quantum Theory does, it assumes the discontinuity of space. Due then to the resulting spacetime disorder, though all else is certainly lost, the Tortoise now turns up at least as fast as Achilles and hence not even this much is rescued. Zeno rejects motion because he shows that a moving object must be where it is not. Hence motion, if to occur, must violate the Law of Contradiction (LNC). Applying the concept of quantum discontinuity, I produce an alternative. If an object is to move discontinuously between two boundary points, A and B, what actually obtains is, rather, that it is nowhere at all in-between A and B. And cannot therefore be at two places in-between A and B. And cannot therefore be where it is not. Thus, LNC is conserved. However, in these conditions, the Law of the Excluded Middle (LEM) fails. To mitigate the undesirability of this effect, I show that LEM fails because LNC holds. Thus, the resulting nonbivalent logic, which is also appropriate for quantized transitions of all kinds, will always turn up nonbivalent, because consistent. And this is not too bad, considering.

My purpose here is purely historical. It is not an attempt to resolve the question as to whether Russell did or did not countenance nonclassical logics, and if so, which nonclassical logics, and still less to demonstrate whether he himself contributed, in any manner, to the development of nonclassical logic. Rather, I want merely to explore and insofar as possible document, whether, and to what extent, if any, Russell interacted with the various, either the various candidates or their, ideas that (...) Dejnožka and others have proposed as potentially influential in Russell’s intellectual reactions to nonclassical logic or to the philosophical concepts that might contribute to his reactions to nonclassical logics.

In his Problems of Philosophy, Bertrand Russell distinguished knowledge by acquaintance and knowledge of truths. This paper argues for a new interpretation of the relationship between these two species of knowledge. I argue that knowledge by acquaintance of an object neither suffices for knowledge that one is acquainted with the object, nor puts a subject in a position to know that she is acquainted with the object. These conclusions emerge from a thorough examination of the central role played by attention (...) in Russell's theory of knowledge. Attention bridges the gap between knowledge by acquaintance and our capacity to form judgements about the objects of acquaintance. (shrink)

The dream of a community of philosophers engaged in inquiry with shared standards of evidence and justification has long been with us. It has led some thinkers puzzled by our mathematical experience to look to mathematics for adjudication between competing views. I am skeptical of this approach and consider Skolem's philosophical uses of the Löwenheim-Skolem Theorem to exemplify it. I argue that these uses invariably beg the questions at issue. I say ?uses?, because I claim further that Skolem shifted his (...) position on the philosophical significance of the theorem as a result of a shift in his background beliefs. The nature of this shift and possible explanations for it are investigated. Ironically, Skolem's own case provides a historical example of the philosophical flexibility of his theorem. Our suspicion ought always to be aroused when a proof proves more than its means allow it. Something of this sort might be called ?a puffed-up proof?.

We offer a reading of Anselm's Ontological Argument inspired by Wittgenstein which focuses on the fact that the “argument” occurs in a prayer addressed to God, making it a strange argument since as a prayer it seems to presuppose its conclusion. We reconstruct the argument as expressive. Within the religious perspective, the issues are to be focused on the right object not to present an argument for the existence of God. While this sort of reading lets us understand much about (...) the argument, it also opens new avenues of criticism, one of which is the problem of worship. (shrink)

Property dualism is enjoying a slight resurgence in popularity, these days; substance dualism, not so much. But it is not as easy as one might think to be a property dualist and a substance materialist. The reasons for being a property dualist support the idea that some phenomenal properties (or qualia) are as fundamental as the most basic physical properties; but what material objects could be the bearers of the qualia? If even some qualia require an adverbial construal (if they (...) are modifications of the thing that is conscious because of them, not properties of something else to which the subject of consciousness is related), then the property dualist can be driven to speculative forms of materialism none of which, at this point, looks more likely to be true than the more modest versions of emergent dualism defended by contemporary substance dualists.

Les vrais systèmes physiques, par contre, ne requièrent aucune interprétation pour lew existence comme systèmes physiques opérationnels.Contrairement à Searle, je soutiens qu'iln'y a (...) pas de démarcation nette entre notre application des formalismes mathématiques standard à des phénomènes physiques comme les oscillations, et notre application des formalismes computationnels aux divers phénomènes physiques qui sont, effectivement ou potentiellement, bien décrits et expliqués pas ces formalismes.

In Pragmatism, James promised his readers a theory of truth. However, many of his readers (even those sympathetic with other parts of James’s work) have concluded that James’s “theory” was little more than a tangle of mistakes. In this chapter, I offer an interpretation and defence of James’s theory of truth. I emphasize James’s truth pluralism.

This volume examines the limitations of mathematical logic and proposes a new approach to logic intended to overcome them. To this end, the book compares mathematical logic with earlier views of logic, both in the ancient and in the modern age, including those of Plato, Aristotle, Bacon, Descartes, Leibniz, and Kant. From the comparison it is apparent that a basic limitation of mathematical logic is that it narrows down the scope of logic confining it to the study of deduction, without (...) providing tools for discovering anything new. As a result, mathematical logic has had little impact on scientific practice. Therefore, this volume proposes a view of logic according to which logic is intended, first of all, to provide rules of discovery, that is, non-deductive rules for finding hypotheses to solve problems. This is essential if logic is to play any relevant role in mathematics, science and even philosophy. To comply with this view of logic, this volume formulates several rules of discovery, such as induction, analogy, generalization, specialization, metaphor, metonymy, definition, and diagrams. A logic based on such rules is basically a logic of discovery, and involves a new view of the relation of logic to evolution, language, reason, method and knowledge, particularly mathematical knowledge. It also involves a new view of the relation of philosophy to knowledge. This book puts forward such new views, trying to open again many doors that the founding fathers of mathematical logic had closed historically. (shrink)

The paper has two parts: First, I describe a relatively popular thesis in the philosophy of propositional attitudes, worthy of the name ‘taking tense seriously’; and I distinguish it from a family of views in the metaphysics of time, namely, the A-theories (or what are sometimes called ‘tensed theories of time’). Once the distinction is in focus, a skeptical worry arises. Some A-theorists maintain that the difference between past, present, and future, is to be drawn in terms of what exists: (...) growing-block theorists eschew ontological commitment to future entities; presentists, to future and past entities. Others think of themselves as A-theorists but exclude no past or future things from their ontology. The metaphysical skeptic suspects that their attempt to articulate an ‘eternalist’ version of the A-theory collapses into merely ‘taking tense seriously’– a thesis that does not imply the A-theory. The second half of the paper is the search for a stable eternalist A-theory. It includes discussion of temporary intrinsics, temporal parts, and truth. (shrink)
