In 'On the nature of truth and falsehood' Russell offers both a multiple relation theory of judgment and a correspondence theory of truth. It has been a prevailing understanding of the Tractatus that Wittgenstein rejects Russell’s multiple relation idea but endorses the correspondence theory. Ramsey took the opposite view. In his 'Facts and Propositions', Ramsey endorses Russell’s multiple relation idea, rejects the correspondence theory, and then asserts that these moves are both due to Wittgenstein. This chapter will argue that Ramsey’s (...) ascriptions are both correct. The extent of the agreement between Ramsey and Wittgenstein will be argued, moreover, to count definitively against standard understandings of Ramsey as a redundancy theorist of truth. Wittgenstein is no correspondence theorist and Ramsey is no redundancy theorist; rather, both philosophers offer identity theories of truth. (shrink)

Gottlob Frege (1848–1925) was unquestionably one of the most important philosophers of all time. He trained as a mathematician, and his work in philosophy started as an attempt to provide an explanation of the truths of arithmetic, but in the course of this attempt he not only founded modern logic but also had to address fundamental questions in the philosophy of language and philosophical logic. Frege is generally seen (along with Russell and Wittgenstein) as one of the fathers of the (...) analytic method, which dominated philosophy in English-speaking countries for most of the twentieth century. His work is studied today not just for its historical importance but also because many of his ideas are still seen as relevant to current debates in the philosophies of logic, language, mathematics and the mind. The Cambridge Companion to Frege provides a route into this lively area of research. (shrink)

The paper is concerned with the idea that the world is the totality of facts, not of things – with what is involved in thinking of the world in that way, and why one might do so. It approaches this issue through a comparison between Wittgenstein’s Tractatus and the identity theory of truth proposed by Hornsby and McDowell.The paper’s positive conclusion is that there is a genuine affinity between these two. A negative contention is that the modern identity theory is (...) vulnerable to a complaint of idealism that the Tractatus can deflect. (shrink)

[A. W. Moore] There are criteria of ineffability whereby, even if the concept of ineffability can never serve to modify truth, it can sometimes serve to modify other things, specifically understanding. This allows for a reappraisal of the dispute between those who adopt a traditional reading of Wittgenstein's Tractatus and those who adopt the new reading recently championed by Diamond, Conant, and others. By maintaining that what the nonsense in the Tractatus is supposed to convey is ineffable understanding, rather than (...) ineffable truth, we can do considerable justice to each of these readings. We can also do considerable justice to the Tractatus. /// [Peter Sullivan] Moore proposes to cut between 'traditional' and 'new' approaches to the Tractatus, suggesting that Wittgenstein's intention is to convey, through the knowing use of nonsense, ineffable understanding. I argue, first, that there is indeed room for a proposal of Moore's general kind. Secondly, though, I question whether Moore's actual proposal is not more in tune with Wittgenstein's later thought than with the attitude of the Tractatus. (shrink)

A way of reading the Tractatus has been proposed which, according to its advocates, is importantly novel and essentially distinct from anything to be found in the work of such previously influential students of the book as Anscombe, Stenius, Hacker or Pears. The point of difference is differently described, but the currently most used description seems to be Goldfarb’s term ‘resolution’ – hence one speaks of ‘the resolute reading’. I’ll shortly ask what resolution is. For now, it is enough that (...) it aims to give full weight to the penultimate section of the Tractatus in which Wittgenstein declares his propositions to be nonsense, where giving full weight to that declaration involves not hearing it as allowing that those ‘nonsensical’ propositions might have another kind of ‘sense’. In that same section Wittgenstein explains that these nonsense propositions, while devoid of meaning, have a use: to make the kind of use of them that their author intends – and so to understand him – requires recognizing that they are nonsense; and through that recognition one ‘surmounts’ these propositions, and is led ‘to see the world aright’. So there is a point to all this nonsense. What point? (shrink)

These new studies of Wittgenstein's Tractatus represent a significant step beyond recent polemical debate.

Crispin Wright and Bob Hale have defended the strategy of defining the natural numbers contextually against the objection which led Frege himself to reject it, namely the so-called ‘Julius Caesar problem’. To do this they have formulated principles (called sortal inclusion principles) designed to ensure that numbers are distinct from any objects, such as persons, a proper grasp of which could not be afforded by the contextual definition. We discuss whether either Hale or Wright has provided independent motivation for a (...) defensible version of the sortal inclusion principle and whether they have succeeded in showing that numbers are just what the contextual definition says they are.

Wittgenstein presents in the Tractatus a variable purporting to capture the general form of proposition. One understanding of what Wittgenstein is doing there, an understanding in line with the ‘new’ reading of his work championed by Diamond, Conant and others, sees it as a deflationary or even an implosive move—a move by which a concept sometimes put by philosophers to distinctively metaphysical use is replaced, in a perspicuous notation, by an innocent device of generalization, thereby dispersing the clouds of philosophy (...) that formerly surrounded the concept. By asking how Wittgenstein supposed his variable to work, and what work he imagined it was fit for, the paper questions the adequacy of that understanding. (shrink)

Wittgenstein, in the Tractatus, conceives the world as ‘the totality of facts’. Type-stratification threatens that conception : the totality of facts is an obvious example of an illegitimate totality. Wittgenstein’s notion of truthoperation evidently has some role to play in avoiding that threat, allowing propositions, and so facts, to constitute a single type. The paper seeks to explain that role in a way that integrates the ‘philosophical’ and ‘technical’ pressures on the notion of an operation.

SELF-INJURY IS A COMPLEX phenomenon that is encountered on a regular basis by health care professionals in mental health care. In this article, I use the concept of epistemic injustice to examine this complex phenomenon and argue that this helps us to understand developments in the way we think about and support people who self-injure. Individuals with lived experience have important knowledge about the nature of self-injury and particularly how it relates to them. If the credibility of this knowledge is (...) denied, for example through accusations of emotional instability, manipulation and attention seeking, then we may cause epistemic and non-epistemic harms. The former by denying the capacity for knowledge, by not... (shrink)

Kant's introduction of a distinctive form of philosophical investigation and proof, known as transcendental, inaugurated a new philosophical tradition. Transcendental Philosophy and Naturalism assesses the present state and contemporary relevance of this tradition. The contributors aim to understand the theoretical structures involved in transcendental explanation, and to assess the contemporary relevance of the transcendental orientation, in particular with respect to contemporary philosophical naturalism. These issues are approached from both naturalistic and transcendental perspectives.

0. My aims in this paper are largely expository: I am more interested in presenting the picture theory than deciding its truth. Even so, I hope that the arguments by which I develop the theory will do something to support it, since I believe that what I will present as Wittgenstein's view is indeed the truth. This is not an admission of insanity, though some things that have been thought intrinsic to the picture theory are things it would be insane (...) to believe. So clearly the view I will present, when compared to the most embracing interpretations, is a partial and selective one. It would be another kind of madness, one I am just as eagre to disown, to suppose that my own favoured selection is the only possible one. That is pretty well the last remark in this paper about other commentators. I trust my reticence entitles me to be presumed catholic until proven nonconformist. (shrink)

This paper demonstrates that the human visual system, the primary sensory conduit for primates, processes ambient energy in a way that obligatorily constructs the objects that we ineluctably perceive. And since our perceptual apparatus processes information only in terms of objects (along with the properties and movements of objects), we are limited in our ability to comprehend ‘what is’ when we move beyond our ordinary world of midsize objects—as, for example, when we address the micro microworld of quantum physics.

Functionalist theories of mind sometimes have viewed consciousness as emerging simply from the computational activity of extremely complex information-processing systems. Empirical evidence suggests strongly, however, that experiences without content ("pure consciousness" events, or "core mystical experience") and devoid of subjectivity (no sense of agency or ownership) do happen. The occurrence of such consciousness, lacking all informational content, counts against any theory that equates consciousness with the mere "flow of information," no matter how intricate.

But logic as it stands, e.g. in Principia Mathematica, can quite well be applied to our ordinary propositions; e.g. from ‘All men are mortal’ and ‘Socrates is a man’ there follows according to this logic ‘Socrates is mortal’, which is obviously correct, even though I equally obviously do not know what structure is possessed by the thing Socrates or the property of mortality. Here they just function as simple objects.

Harm minimisation has been proposed as a means of supporting people who self-injure. When adopting this approach, rather than trying to stop self-injury immediately the person is allowed to injure safely whilst developing more appropriate ways of dealing with distress. The approach is controversial as the health care professional actively allows harm to occur. This paper will consider a specific objection to harm minimisation. That is, it is a misguided collaboration between the health care professional and the person who self-injures (...) that is morally and clinically questionable. The objection has two components. The first component is moral in nature and asserts that the health care professional is complicit in any harm that occurs and as a result they can be held morally responsible and subject to moral blame. The second component is clinical in nature and suggests that harm minimisation involves the health care professional in colluding in the perpetuation of self-injury. This element of the objection i... (shrink)

This paper provides a response to Hanna Pickard and Stephen Pearce’s paper ‘Balancing costs and benefits: a clinical perspective does not support a harm minimisation approach for self-injury outside of community settings.’ This paper responded to my article ‘Should healthcare professionals sometimes allow harm? The case of self-injury.’ There is much in the paper that I would agree with, but I feel it is important to respond to a number of the criticisms of my paper in order to clarify my (...) position and to facilitate ongoing debate in relation to this important issue.

We correct a misunderstanding by Hale and Wright of an objection we raised earlier to their abstractionist programme for rehabilitating logicism in the foundations of mathematics.

At the age of 20, and fresh from his undergraduate studies in mathematics, Ramsey set about writing what would be his first substantial publication, his 1923 Critical Notice of Wittgenstein’s Tractatus. It is hard for modern students of that book, who negotiate its obscurities with generations of previous commentary to serve as guides, to appreciate the task Ramsey confronted; and, to the extent that one can appreciate it, it is hard not to feel intimidated by the brilliance of his success. (...) His Critical Notice made Ramsey the first of Wittgenstein’s interpreters.1 In my view it makes him, still, the best. I want to illustrate that here by considering what light his remarks cast on a single passage of the book, in which Wittgenstein advances what might be called his theory of judgement. (shrink)

The aim of this article is to motivate and outline a dialogical perspective on agency that accommodates centrifugal and centripetal tendencies in current cultural theories of agency. To complement approaches that assume a high degree of integration and clarity, we emphasise the diversity of agency as it is experienced in the open-ended dialogical relationship with a particular other. While these former approaches to agency provide us with the means to examine the influence of social processes such as division of labour (...) and reproduction of community, they tend to underplay the importance of agency as it is embodied and experienced in the lives of particular people. To reflect on this aspect of agency, we will draw extensively on Bakhtin's work, which crosses boundaries between philosophy, psychology and literary criticism, and which is concerned to understand what is personal in activity. In terms of agency, his work draws our attention to the sense of responsibility and potentiality that imbues our dialogues with particular others, the aesthetics and ethics involved in dialoguing with the other, and the sense of dilemmatic choice and intonation that is involved in our dialogue with the other.

Self‐evidently the standard work on the topic its whole title defines, Sir Michael Dummett’s Frege: Philosophy of Mathematics (FPM) is also the most profound and creative discussion in recent decades of the problems confronting the branch of philosophy mentioned after the colon. Chapters 14‐18 and 23‐24 of this book constitute a continuous and challenging diagnosis of these problems.1 They culminate in the proposal that these problems present an impasse that can be escaped only by adopting a constructivist understanding of mathematical (...) generality. Dummett’s case for that conclusion is no less complexly over‐layered than the problems themselves. By contrast my aims in this discussion of his case are limited in various ways, and three of these should be mentioned straightaway. In the first place, I will aim to consider a case that, if sound, would warrant a constructivist understanding of generality in mathematics generally (and so I will not be considering lines of argument specific to set theory, or to those parts of mathematics plausibly dependent on notions intrinsic to set theory). Secondly, I aim to consider a case which, while general in its application within mathematics, is not more general than that (and so would not warrant a broader anti‐realism). Reasons for these first two limitations are discussed in section 1. A third limitation is that I will aim only to understand Dummett’s case, and not to assess it. Perhaps some will think this third limitation calls for explanation or excuse. I think it needs no excuse and that the explanation is obvious. When we are dealing with fundamentally important work by a great philosopher, understanding is often ambition enough. In Michael Dummett’s work, that is what we are dealing with. (shrink)

In a recent book, Robert Trueman develops a version of the identity theory of truth, the theory that true propositions are not in some kind of correspondence with, but are rather identical with, facts. He claims that this theory ‘collapses the gap between mind and world’. Whether it does so will obviously depend on how the theory is to be understood, which in turn depends on the argumentative route to it. Trueman’s route is clear, rigorous, and free of extravagant assumptions. (...) Perhaps because of those merits it seems obvious that it falls short of the claim he makes for it. But there are difficult questions about the nature of the shortfall and about what in the character of Trueman’s philosophical approach prevents him from appreciating it. The paper explores those questions through a comparison with Moore’s ‘original’ identity theory and the Idealist philosophy he directed it against. (shrink)
