Turing's three philosophical lessons and the philosophy of information

In this article, I outline the three main philosophical lessons that we may learn from Turing's work, and how they lead to a new philosophy of information. After a brief introduction, I discuss his work on the method of levels of abstraction (LoA), and his insistence that questions could be meaningfully asked only by specifying the correct LoA. I then look at his second lesson, about the sort of philosophical questions that seem to be most pressing today. Finally, I focus on the third lesson, concerning the new philosophical anthropology that owes so much to Turing's work. I then show how the lessons are learned by the philosophy of information. In the conclusion, I draw a general synthesis of the points made, in view of the development of the philosophy of information itself as a continuation of Turing's work.

Not Belonging to one’s Self: Affect on Facebook’s Site Governance page

This article makes a contribution to a growing number of works that discuss affect and social media. I use Freudian affect theory to analyse user posts on the public Site Governance Facebook page. Freud’s work may help us to explore the affectivity within the user narratives and I suggest that they are expressions of alienation, dispossession and powerlessness that relate to the users’ relations with Facebook as well as to their internal and wider social relations. The article thus introduces a new angle on studies of negative user experiences that draws on psychoanalysis and critical theory

The role of empathy in psychoanalytic psychotherapy: A historical exploration

Empathy is one of the most consistent outcome predictors in contemporary psychotherapy research. The function of empathy is particularly important for the development of a positive therapeutic relationship: patients report positive therapeutic experiences when they feel understood, safe, and able to disclose personal information to their therapists. Despite its clear significance in the consulting room and psychotherapy research, there is no single, consensual definition of empathy. This can be accounted by the complex and multi-faceted nature of empathy, as well as the ambiguous and conflicting literature surrounding it. This paper provides a historical exploration of empathy and its impact on the therapeutic relationship across the most influential psychoanalytic psychotherapies: classic psychoanalysis, person-centered therapy and self-psychology. By comparing the three clinical schools of thought, the paper identifies significant differences in the function of transference and therapist’s role. Then, drawing on the different clinical uses of empathy, the paper argues that the earlier uses of empathy (most notably through Jaspers’ and Freud’s writings) are limited to its epistemological (intellectual or cognitive) features, whilst person-centered and self-psychology therapies capitalise on its affective qualities. Finally, the paper provides a rationale for further study of the overarching features of empathy in contemporary psychotherapy research

Fit for work? Health, employability and challenges for the UK welfare reform agenda

This article introduces a special issue of Policy Studies entitled “Fit for work? Health, employability and challenges for the UK welfare reform agenda”. Growing from a shared concern over the need to expand the evidence base around the processes that led to large numbers of people claiming disability benefits in the UK, it brings together contributions from leading labour market and social policy researchers providing evidence and commentary on major reforms to Incapacity Benefit (IB) in the UK. This special issue address three key questions: what are the main causes of the long-term rise in the number of people claiming IBs; what will reduce the number of claimants; and what is likely to deliver policy effectively and efficiently? This introduction first explains and examines the challenges to reforms to IB in the UK, and then, in conclusion, highlights the answers to the previous three questions – first, labour market restructuring and marginalisation have driven the rise in numbers claiming IBs. Second, economic regeneration in the Britain’s less prosperous areas coupled with intensive and sustained supply-side support measures will bring numbers down. Third, delivery need to be flexible and tailored to individual needs and needs to be able to access local and expert knowledge in a range of organisations, including Job Centre Plus, the NHS as well as the private and voluntary sectors

Recognising Desire: A psychosocial approach to understanding education policy implementation and effect

It is argued that in order to understand the ways in which teachers experience their work - including the idiosyncratic ways in which they respond to and implement mandated education policy - it is necessary to take account both of sociological and of psychological issues. The paper draws on original research with practising and beginning teachers, and on theories of social and psychic induction, to illustrate the potential benefits of this bipartisan approach for both teachers and researchers. Recognising the significance of (but somewhat arbitrary distinction between) structure and agency in teachers’ practical and ideological positionings, it is suggested that teachers’ responses to local and central policy changes are governed by a mix of pragmatism, social determinism and often hidden desires. It is the often underacknowledged strength of desire that may tip teachers into accepting and implementing policies with which they are not ideologically comfortable

On the moment limit of quantum observables, with an application to the balanced homodyne detection

We consider the moment operators of the observable (i.e. a semispectral measure or POM) associated with the balanced homodyne detection statistics, with paying attention to the correct domains of these unbounded operators. We show that the high amplitude limit, when performed on the moment operators, actually determines uniquely the entire statistics of a rotated quadrature amplitude of the signal field, thereby verifying the usual assumption that the homodyne detection achieves a measurement of that observable. We also consider, in a general setting, the possibility of constructing a measurement of a single quantum observable from a sequence of observables by taking the limit on the level of moment operators of these observables. In this context, we show that under some natural conditions (each of which is satisfied by the homodyne detector example), the existence of the moment limits ensures that the underlying probability measures converge weakly to the probability measure of the limiting observable. The moment approach naturally requires that the observables be determined by their moment operator sequences (which does not automatically happen), and it turns out, in particular, that this is the case for the balanced homodyne detector.Comment: 22 pages, no figure

Quantization and noiseless measurements

In accordance with the fact that quantum measurements are described in terms of positive operator measures (POMs), we consider certain aspects of a quantization scheme in which a classical variable $f:\R^2\to \R$ is associated with a unique positive operator measure (POM) $E^f$, which is not necessarily projection valued. The motivation for such a scheme comes from the well-known fact that due to the noise in a quantum measurement, the resulting outcome distribution is given by a POM and cannot, in general, be described in terms of a traditional observable, a selfadjoint operator. Accordingly, we notice that the noiseless measurements are the ones which are determined by a selfadjoint operator. The POM $E^f$ in our quantization is defined through its moment operators, which are required to be of the form $\Gamma(f^k)$, $k\in \N$, with $\Gamma$ a fixed map from classical variables to Hilbert space operators. In particular, we consider the quantization of classical \emph{questions}, that is, functions $f:\R^2\to\R$ taking only values 0 and 1. We compare two concrete realizations of the map $\Gamma$ in view of their ability to produce noiseless measurements: one being the Weyl map, and the other defined by using phase space probability distributions.Comment: 15 pages, submitted to Journal of Physics

Introduction : narcissism, melancholia and the subject of community.

Sigmund Freud’s twin papers, ‘On Narcissism: An Introduction’ (1914) and ‘Mourning and Melancholia’ (1917 [1915]), take as their formative concern the difficulty of setting apart the ‘inner’ and the ‘outer’ worlds, and of preserving a stable image of a boundaried self. Whilst it is true that the term narcissism especially has come to be deployed in ways that seem foreign to the complexities of Freud’s 1914 paper (by its reduction to a personality disorder or its use as a broad-brush cultural diagnosis), we suggest in this introductory chapter that neither narcissism nor melancholia can be thought about today without expressing some debt to Freudian metapsychology. However, whereas Freud was most evidently concerned to describe the structure of ego-formation, subsequent commentators have preferred to emphasize the cultural and normative dimensions of these terms. Accordingly, we consider the respective discursive histories of narcissism and melancholia and find that although they have been put to work in very different ways they remain grounded by a shared concern with mechanisms of relation and identification. Indeed, this shared concern is the basis upon which they’ve been most productively reanimated in recent years: the rise of melancholia as a critical aid to the study of cultural displacement and dispossession, and the determined redemption of narcissism from its pejorative characterization as fundamentally anti-social. We argue that what is most noteworthy in this post-Freudian literature is the increasing relevance of metapsychology to social and political theory. The language of psychoanalysis, extrapolated from the clinic, permits a detailed examination of the boundaries which construct and challenge the terms of social solidarity. Specifically, this takes place though careful reading of the complex practices of (dis)identification at the heart of ego-formation (at both individual and group levels), and the associated mechanisms of defence, for example: introjection, incorporation, projective-identification, and splitting. By recognising the complexity of how communities get made, and connecting this with recent literature on counter publics and the commons, we demonstrate that Freud’s frameworks of narcissism and melancholia remain essential for any contemporary understanding of political association
