This article develops a logical (or semantic) response to scepticism about the existence of an external world. Specifically, it is argued that any doubt about the existence of an external world can be proved to be false, but whatever appears to be doubt about the existence of an external world that _cannot_ be proved to be false is nonsense, insofar as it must rely on the assertion of something that is logically impossible. The article further suggests that both G. E. (...) Moore and Ludwig Wittgenstein worked towards the same solution but left their work unfinished. (shrink)

This introductory chapter presents the reader with various ways of approaching the topic ‘Wittgenstein and the creativity of language’. It is argued that any serious account of the questions arising from this joint consideration of, on the one hand, this great genius of philosophy and, on the other, the varieties of speech, text, action and beauty which go under the heading ‘the creativity of language’ will have to appreciate the potential of both, in terms of breadth as well as depth. (...) First, the chapter points out a way of understanding Wittgenstein’s discussion of rules and rule-following in relation to meaning and normativity which, in virtue of respecting Wittgenstein’s own creativity as a writer, does not fall prey to a widespread source of misunderstanding. Next, Wittgenstein’s uses of language receive some additional attention (i.e. his use of analogies, metaphors, punctuation and other literary and rhetorical devices), before a glimpse is offered of an unravelling of the knot that is Wittgenstein and the creativity of language. The multiple interrelated threads here lead into areas of human concern ranging from the philosophy of language and logic through to ethics, aesthetics and politics. Finally, the chapter offers an overview of the contents of the book from the perspective of its editors. (shrink)

Logic played an important role in Wittgenstein’s work over the entire period of his philosophizing, from both the point of view of the philosopher of logic and that of the logician. Besides logical analysis, there is another kind of logical activity that characterizes Wittgenstein’s philosophical work after a certain point during his experience as a soldier and, later, as an officer in the First World War – if not earlier. This other kind of logical activity has to do with what (...) appears to be the literary form of Wittgenstein’s philosophical prose, and it is likely to be seen as the most modernist feature of his preoccupation with logic.

This essay discusses Wittgenstein's conception of logic, early and late, and some of the types of logical system that he constructed. The essay shows that the common view according to which Wittgenstein had stopped engaging in logic as a philosophical discipline by the time of writing Philosophical Investigations is mistaken. It is argued that, on the contrary, logic continued to figure at the very heart of later Wittgenstein's philosophy; and that Wittgenstein's mature philosophy of logic contains many interesting thoughts that (...) have gone widely unnoticed.

The logical problem of artificial intelligence—the question of whether the notion sometimes referred to as ‘strong’ AI is self-contradictory—is, essentially, the question of whether an artificial form of life is possible. This question has an immediately paradoxical character, which can be made explicit if we recast it (in terms that would ordinarily seem to be implied by it) as the question of whether an unnatural form of nature is possible. The present paper seeks to explain this paradoxical kind of possibility (...) by arguing that machines can share the human form of life and thus acquire human mindedness, which is to say they can be intelligent, conscious, sentient, etc. in precisely the way that a human being typically is.

What is philosophy? How is it possible? This essay constitutes an attempt to contribute to a better understanding of what might be a good answer to either of these questions by reflecting on one particular characteristic of philosophy, specifically as it presents itself in the philosophical practice of Socrates, Plato and Wittgenstein. Throughout this essay, I conduct the systematic discussion of my topic in parallel lines with the historico-methodological comparison of my three main authors. First, I describe a certain neglected (...) aspect of the Socratic method. Then, exploring the flipside of this aspect, I show that despite the fact that both Socrates and Wittgenstein understand their philosophical approaches as being essentially directed at the particular problems and modes of understanding that are unique to single individuals, they nevertheless aspire to philosophical understanding of the more ‘mundane’ kind that is directed at the world. Finally, interpreting parts of Plato’s dialogues Phaedrus and Laches, I further develop my case for seeing the role of mutual understanding in philosophy as fundamentally twofold, being directed both at the individual and what they say (the word), and at things that are ‘external’ to this human relation at any particular moment of philosophical understanding (the world).

This article presents a theory of intuitive skill in terms of three constitutive elements: getting things right intuitively, not getting things wrong intuitively, and sceptical ability. The theory draws on work from a range of psychological approaches to intuition and expertise in various domains, including arts, business, science, and sport. It provides a general framework that will help to further integrate research on these topics, for example building bridges between practical and theoretical domains or between such apparently conflicting methodologies as (...) a heuristics and biases approach on the one hand and one based on naturalistic decision-making on the other. In addition, the theory provides a clearer and more precise account of relevant concepts, which will help to inspire new directions for future research. Intuitive skill is defined as a high level of intuitive ability, that is, the ability to make good use of intuition; specifically, a high level of ability at either getting things right intuitively, not getting things wrong intuitively, or sceptical ability, where the latter is the ability to detect instances of getting things wrong intuitively so as to avoid forming incorrect intuitive judgements, which may itself be partly intuitive.

We argue that Wittgenstein’s philosophical perspective on Gödel’s most famous theorem is even more radical than has commonly been assumed. Wittgenstein shows in detail that there is no way that the Gödelian construct of a string of signs could be assigned a useful function within (ordinary) mathematics. — The focus is on Appendix III to Part I of Remarks on the Foundations of Mathematics. The present reading highlights the exceptional importance of this particular set of remarks and, more specifically, emphasises (...) its refined composition and rigorous internal structure. (shrink)

A review of Sebastian Sunday Grève´s and Jakub Mácha´s Wittgenstein and the Creativity of Language.

What is creativity? It is clearly something we know by seeing it manifested in a multitude of different ways and contexts. It could perhaps stand as an emblematic example of the limitations of a general explanative account. In this anthology the editors have orchestrated an exceptionally inspiring collection of essays that explore the vast examples of creative language used in Wittgenstein's philosophical practice and the creative potentiality of language overall. The anthology consists of eleven essays divided into introduction, overture, and (...) three parts containing three essays each. The collection offers a wide scope, ranging from styles of writing and aesthetic forms of expression to ethical reflections and... (shrink)

This volume of new essays presents groundbreaking interpretations of some of the most central themes of Wittgenstein's philosophy. A distinguished group of contributors demonstrates how Wittgenstein's thought can fruitfully be applied to contemporary debates in epistemology, metaphilosophy and philosophy of language. The volume combines historical and systematic approaches to Wittgensteinian methods and perspectives, with essays providing detailed analysis that will be accessible to students as well as specialists. The result is a rich and illuminating picture of a key figure in (...) twentieth-century philosophy and his continuing importance to philosophical study. (shrink)

'Everyone knows what attention is’ according to William James. Much work on attention in psychology and neuroscience cites this famous phrase only to quickly dismiss it. But James is right about this: ‘attention’ was not introduced into psychology and neuroscience as a theoretical concept. I argue that we should therefore study attention with broadly the same methodology that David Marr has applied to the study of perception. By focusing more on Marr's Computational Level of analysis, we arrive at a unified (...) answer to the question of what attention is, what role it plays in the mind, and why organisms like us have that capacity. I propose a methodology for studying attention at Marr's Computational Level that optimizes in a three-dimensional space: it should capture core aspects of our first-person experience of attention, be explanatorily powerful in psychology and neuroscience, and fertile in an interdisciplinary context. I show how this methodology leads to what I call the priority structure account of attention. Attention is what organizes current information to make it more useful for the organism. We can identify it by four features. Attention, in this way, helps a cognitive system to integrate its informational state with its current motivational state. I describe how this account improves on alternatives and shows why attention is a useful concept in many disciplines and for connecting them. -/- This article is categorized under: Philosophy > Psychological Capacities Psychology > Attention Philosophy > Foundations of Cognitive Science.

Exploring Rhees's analogy between everyday conversation and literature, the paper suggests a conception of form that encourages us to see literary works as contributions to conversation in virtue of their concern. How we might read for the concern of a literary work is exemplified by readings of Ibsen's Ghosts and The Wild Duck. These readings suggest that Rhees's analogy not only throws light on the communicative powers of literature: viewing everyday talk in the light of works of literature also gives (...) us a better grasp of what goes on in conversation.

The normative force of evidence can seem puzzling. It seems that having conclusive evidence for a proposition does not, by itself, make it true that one ought to believe the proposition. But spelling out the condition that evidence must meet in order to provide us with genuine normative reasons for belief seems to lead us into a dilemma: the condition either fails to explain the normative significance of epistemic reasons or it renders the content of epistemic norms practical. The first (...) aim of this paper is to spell out this challenge for the normativity of evidence. I argue that the challenge rests on a plausible assumption about the conceptual connection between normative reasons and blameworthiness. The second aim of the paper is to show how we can meet the challenge by spelling out a concept of epistemic blameworthiness. Drawing on recent accounts of doxastic responsibility and epistemic blame, I suggest that the normativity of evidence is revealed in our practice of suspending epistemic trust in response to impaired epistemic relationships. Recognizing suspension of trust as a form of epistemic blame allows us to make sense of a purely epistemic kind of normativity the existence of which has recently been called into doubt by certain versions of pragmatism and instrumentalism.

Several studies have identified entrepreneurship as a key factor in wealth creations in addition to associating certain personality characteristics to its growth. The question is to what extent have these wealth creations performed ethically. The present study is set to explore the cognitive orientation and demographic factors that are associated with unethical business. Two hundred and fifty-six owner–managers in the age range of 24 to 68 years participated in the survey study. Male participants accounted for 63.3 per cent, while female (...) participants were 36.7 per cent. The results indicate that risk taking and gender factors were consistently and statistically significant predictors of unethical business across the three groups in this study. The group situation appears to have effect on the individual contribution to unethical business. Implications are drawn from the results, and priorities are established for future research. (shrink)

It is often argued that there are no practical reasons for belief because we could not believe for such reasons. A recent reply by pragmatists is that we can often believe for practical reasons because we can often cause our beliefs for practical reasons. This paper reveals the limits of this recently popular strategy for defending pragmatism, and thereby reshapes the dialectical options for pragmatism. I argue that the strategy presupposes that reasons for being in non-intentional states are not reducible (...) to reasons to act. Pragmatists who want to preserve a motivational constraint on reasons therefore have exactly two options: either arguing that there are irreducible reasons for being in non-intentional states ; or arguing that we can believe directly for practical reasons. I argue that the prospects for the former option are dim because irreducible reasons to be in states are hard to square with the motivational constraint on reasons. Returning to the more traditional route of arguing for pragmatism by defending a version of doxastic voluntarism therefore seems to be the more promising way for pragmatists to go. (shrink)

The neutrosophic automorphisms of a neutrosophic groups G (I) , denoted by Aut(G (I)) is a neu-trosophic group under the usual mapping composition. It is a permutation of G (I) which is also a neutrosophic homomorphism. Moreover, suppose that X1 = X(G (I)) is the neutrosophic group of inner neutrosophic auto-morphisms of a neutrosophic group G (I) and Xn the neutrosophic group of inner neutrosophic automorphisms of Xn-1. In this paper, we show that if any neutrosophic group of the sequence (...) G (I), X1, X2, … is the identity, then G (I) is nilpotent. (shrink)

According to the principle that ‘ought’ implies ‘can’, it is never the case that you ought to do something you cannot do. While many accept this principle in some form, it also has its share of critics, and thus it seems desirable if an argument can be offered in its support. The aim of this paper is to examine a particular way in which the principle has been defended, namely, by appeal to considerations of fairness. In a nutshell, the idea (...) (due to David Copp) is that moral requirements we cannot comply with would be unfair, and there cannot be unfair moral requirements. I discuss several ways of spelling out the argument, and argue that all are unsatisfactory for a variety of reasons. (shrink)

Many of our attitudes are non-culpable: there was nothing that we should have done to avoid holding them. I argue that we can still be blameworthy for non-culpable attitudes: they can impair our relationships in ways that make our full practice of apology and forgiveness intelligible. My argument poses a new challenge to indirect voluntarists, who attempt to reduce all responsibility for attitudes to responsibility for prior actions and omissions. Rationalists, who instead explain attitudinal responsibility by appeal to reasons-responsiveness, can (...) make sense of blameworthiness for non-culpable attitudes. In response, voluntarists could propose a revision of our actual practices. This would lead us into a quite different debate. (shrink)

According to ordinary language philosophy (OLP), philosophical problems can be solved by investigating ordinary language, often because the problems stem from its misuse. According to ideal language philosophy (ILP), on the other hand, philosophical problems exist because ordinary language is flawed and has to be improved or replaced by constructed languages that do not exhibit these flaws. OLP and ILP together make up linguistic philosophy, the view that philosophical problems are problems of language. Linguistic philosophy is opposed to what may (...) be called, for lack of a better word, ‘traditional philosophy’ (TP), the view that philosophical problems can be solved by discovering non-linguistic facts. In the following, OLP, ILP, and TP are taken to be methodologies, that is, frameworks in which to interpret and evaluate different philosophical methods (i.e., argumentative strategies). The two linguistic methodologies are discussed separately with TP as a foil, and then used to interpret the status of different philosophical methods. While each of the methods discussed here finds a plausible interpretation in each methodology, there are other arguments for and against linguistic philosophy in general, and for and against ILP and OLP in particular. As none of these arguments is decisive, I conclude with a superficial moral about peaceful co-existence. (shrink)

Following the liberation of Poland 1945, the childrens organization of the Jewish-Socialdemocratic "Bund" SKIF formed itself anew and remained in existence until the communists' ban of social democratic organizations. Starting with the first post-war conference of the International of social democratic children and youth education in October 1945 until the mid-sixties the SKIF played a recognizable role within these international structures of the "Falcons" movement. In the late forties the SKIF simultaneously existed in Paris, where a successor organization is still (...) active, and in Brussels. During the seventies and eighties a "SKIF-ist" holiday colony existed in New York and from 1950 until this day further groups exist in Melbourne. Since 1945 the SKIF has existed primarily as an organization of survivors and their children. Later it managed to develop a new function and to offer an educational model for the following generations of Jewish children, which lies beyond religion and Zionism. (shrink)

What is attention? How does attention shape consciousness? In an approach that engages with foundational topics in the philosophy of mind, the theory of action, psychology, and the neurosciences this book provides a unified and comprehensive answer to both questions. Sebastian Watzl shows that attention is a central structural feature of the mind. The first half of the book provides an account of the nature of attention. Attention is prioritizing, it consists in regulating priority structures. Attention is not another (...) element of the mind, but constituted by structures that organize, integrate, and coordinate the parts of our mind. Attention thus integrates the perceptual and intellectual, the cognitive and motivational, and the epistemic and practical. The second half of the book concerns the relationship between attention and consciousness. Watzl argues that attentional structure shapes consciousness into what is central and what is peripheral. The center-periphery structure of consciousness cannot be reduced to the structure of how the world appears to the subject. What it is like for us thus goes beyond the way the world appears to us. On this basis, a new view of consciousness is offered. In each conscious experience we actively take a stance on the world we appear to encounter. It is in this sense that our conscious experience is our subjective perspective. (shrink)

Conceptual engineering is the enterprise of evaluating and improving our representational devices. But how should we conduct this enterprise? One increasingly popular answer to this question proposes that conceptual engineering should proceed in terms of the functions of our representational devices. In this paper, we argue that the best way of understanding this suggestion is in terms of normative functions, where normative functions of concepts are, roughly, things that they allow us to do that matter normatively (for example, things in (...) virtue of which we have normative reasons to have these concepts). Not only does this introduce a novel view about functions to the literature. This proposal also fits more naturally than the alternatives with conceptual engineering as a normative enterprise, and it allows functions to play all of the explanatory roles assigned to them in the conceptual engineering literature. Our discussion of the explanatory advantages of normative functions also advances the understanding of the ways in which concepts can be authoritative, what this means for conceptual engineering, and highlights the importance of political philosophy for thinking about conceptual engineering in practice. Furthermore, the paper explicates what kind of role considerations about function can and should actually play in conceptual engineering. (shrink)

Representations are not only used in our folk-psychological explanations of behaviour, but are also fruitfully postulated, for example, in cognitive science. The mainstream view in cognitive science maintains that our mind is a representational system. This popular view requires an understanding of the nature of the entities they are postulating. Teleosemantic theories face this challenge, unpacking the normativity in the relation of representation by appealing to the teleological function of the representing state. It has been argued that, if intentionality is (...) to be explained in teleological terms, then the function of a state cannot depend on its phylogenetical history, given the metaphysical possibility of a duplicate of an intentional being that lacks an evolutionary history. In this paper, I present a method to produce, according to our current knowledge in genetic engineering, human-like individuals who are not the product of natural selection in the required sense. This variation will be used to shed light on the main replies that have been offered in the literature to the Swampman thought experiment. I argue that these replies are not satisfactory: representations should better not depend on natural selection. I conclude that a non-etiological notion of function is to be preferred for characterizing the relation of representation. (shrink)

The three ancient philosophical introductions translated in this volume flesh out our picture of what it would have been like to sit in a first-year Philosophy course in ancient Alexandria. Ammonius (AD 445-517/26) set up a new teaching programme in Alexandria with up to six introductions to the philosophy curriculum, which made it far more accessible, and encouraged its spread from Greek to other cultures. This volume's three introductory texts include one by his student Olympiodorus and one each by Olympiodorus' (...) students Elias and David. Elias' Introductions to Philosophy starts with six definitions of Philosophy, to which David adds replies to the sceptical question whether there is such a thing as Philosophy. Olympiodorus' text translated here is an Introduction to Logic, which is just one of the three introductions he wrote himself. (shrink)
