Recent accounts on the global workspace theory suggest that consciousness involves transient formations of functional connections in thalamo-cortico-cortical networks. The level of connectivity in these networks is argued to determine the state of consciousness. Emotions are suggested to play a role in shaping consciousness, but their involvement in the global workspace theory remains elusive. In the present study, the role of emotion in the neural workspace theory of consciousness was scrutinized by investigating, whether unconscious and conscious display of emotional compared (...) to neutral facial expressions would differentially modulate EEG coherence. EEG coherence was measured by means of computing an average EEG coherence value between the frontal, parietal, and midline scalp sites. Objective awareness checks evidenced that conscious identification of the masked facial expressions was precluded. Analyses revealed reductions in EEG coherence in the lower frequency range for the masked as compared to unmasked neutral facial expressions. Crucially, a decline in EEG coherence was not observed for the emotional facial expressions. In other words, the level of EEG coherence did apparently vary as a function of awareness, but not when emotion was involved. The current finding suggests that EEG coherence is modulated by unconscious emotional processes, which extends common views on the global workspace architecture of consciousness. (shrink)

Behrendt & Young (B&Y) propose an explanation for schizophrenia in terms of a cortical default in the interaction between consciousness and cognition. However, schizophrenia more likely involves miscommunication between subcortical and cortical affective circuits in the brain, a default in the interaction between consciousness and emotion. The typical “affective” nature of hallucinations in schizophrenia provides compelling evidence for subcortical involvement.

Lewis proposes a solution for bridging the gap between cognitive-psychological and neurobiological theories of emotion in terms of dynamic systems modeling. However, an important brain network is absent in his account: the neuroendocrine system. In this commentary, the dynamic features of the cross-talk between the hypothalamic-pituitary-adrenal (HPA) and gonadal (HPG) axes are discussed within a triple-balance model of emotion.

Transcranial magnetic stimulation (TMS) is a method capable of transiently modulating neural excitability. Depending on the stimulation parameters information processing in the brain can be either enhanced or disrupted. This way the contribution of different brain areas involved in mental processes can be studied, allowing a functional decomposition of cognitive behavior both in the temporal and spatial domain, hence providing a functional resolution of brain/mind processes. The aim of the present paper is to argue that TMS with its ability to (...) draw causal inferences on function and its neural representations is a valuable neurophysiological tool for investigating the causal basis of neuronal functions and can provide substantive insight into the modern interdisciplinary and (anti)reductionist neurophilosophical debates concerning the relationships between brain functions and mental abilities. Thus, TMS can serve as a heuristic method for resolving causal issues in an arena where only correlative tools have traditionally been available. (shrink)

Seeking to unlock the secrets of consciousness, neuroscientists have been studying neural correlates of sensory awareness, such as meaningless randomly moving dots. But in the natural world of species' survival, “raw feelings” mediate conscious adaptive responses. Merker connects the brainstem with vigilance, orientating, and emotional consciousness. However, depending on the brain's phylogenetic level, raw feeling takes particular forms. (Published Online May 1 2007).

Mazur & Booth's (1998) target article concerns basal and reciprocal relations between testosterone and dominance, and has its roots in Mazur's (1985; 1994) model of primate dominance-submissiveness interactions. Threats are exchanged in these interactions and a psychological stress-manipulation mechanism is suggested to operate, making sure that face-to-face dominance contests are usually resolved without aggression. In this commentary, a recent line of evidence from human research on the relation between testosterone, cortisol, and vigilant (dominant) and avoidant (submissive) responses to threatening “angry” (...) faces is discussed. Findings, to a certain extent, converge with Mazur & Booth's theorizing. However, the strongest relations have been found in subliminal exposure conditions, suggesting that biological instead of psychological mechanisms are involved. (shrink)

Austin takes on the problem of other minds, of how to respond to the question ‘how do you know?’, if this question is raised with regard to the thoughts, feelings, sensations, minds of other creatures. This problem has traditionally been understood as the problem of justifying our belief in the existence of other minds. Austin argues that believing in other persons, in authority and testimony, is an essential part of the act of communicating, and as such is an irreducible part (...) of our experience. While we can state certain advantages of communicative performances, there is no justification for our doing them as such. (shrink)

On the meta-level, ‘A Plea for Excuses’, sometimes regarded as the manifesto of ordinary language philosophy, illustrates Austin’s method of approaching philosophical issues, by patiently analysing the subtleties of ordinary language, by example. On the object level, the key distinction with regard to human actions that appear to be worthy of blame, Austin holds to be between a justification, which denies that the performed action was wrong, and an excuse, which instead denies that the agent was responsible for performing it. (...) Austin gives careful attention to particular cases of exculpatory speech, including precise word order and varying emphasis, etymological studies, and the special function of adverbial qualifying phrases, and shows how legal precedents and abnormal psychology may also be helpful in understanding why some efforts to excuse fail. In the final analysis, excuses are properly seen as setting limits to the ascription of moral responsibility, by stating explicitly how they differ from the more usual cases. (shrink)

Criticises G. E. Moore’s highly influential proposal that ascriptions of agent ability implying freedom of choice or action, what the agent could do, are analyzable as conditional statements regarding what the agent would do under certain circumstances. Austin objects against Moore that some uses of ‘if’ are non-conditional and goes on to examine the uses of these non-conditional cases. Moore’s proposal also lies at the heart of some compatibilist theories of free will and determinism. Austin argues determinism to be a (...) pseudo-problem, so long as it remains a notion that is not itself clear cut. (shrink)

Austin attacks the view that language is referential, based on the simplistic division of utterances into the ‘descriptive’ and ‘evaluative’, using his notion of performative utterances. Such utterances, in the appropriate circumstances, are neither descriptive nor evaluative, but count as actions, i.e., create the situation rather than describing or reporting on it. In saying ‘I promise to go’ one is making a promise, not stating that one is making it. A performative promise is not, and does not involve, the statement (...) that one is promising. It is an act of a distinctive sort, the very sort named by the performative verb. And, according to Austin, making explicit what one is doing is not describing what one is doing or stating that one is doing it. (shrink)

Deals with the question of whether there is a use of ‘is true’ that is the primary or generic name for that which at bottom we are always saying ‘is true’. Austin discusses the views that truth is primarily a property of beliefs and of true statements. He goes on to argue that the word ‘true’ denotes the validity of an intended correspondence between a representation and what it represents, and dismantles confusions about the meaning of the words that underlie (...) such a view, such as ‘fact that’ and ‘corresponds’.

Austin discusses the existence, origin, and resemblance of concepts, primarily by discussing the meaning of ‘concept’ and ‘universal’. He argues that, although sometimes it may not be harmful to talk about concepts, we neither understand the meaning of ‘concept’, nor the meaning of ‘acquiring and possessing concepts’, nor a view of concept resemblance as non-sensuous acquaintance or awareness, challenging philosophers who couch their theories in such terms to illuminating them first.

‘Agathon and Eudaimonia in the Ethics of Aristotle’ is a response to an article on the meaning of Agathon in the Ethics of Aristotle, published by H. A. Pritchard in 1935. In this paper, Pritchard argued that Aristotle regarded Agathon to mean ‘conducive to our happiness’ and, consequently, that he maintained that every deliberate action stems, ultimately, from the desire to become happy. Austin finds fault with this view: first, Agathon in Aristotle does not have a single meaning, and a (...) fortiori not the one Pritchard suggested; secondly, if one had to summarise the meaning of ‘being agathon’ in one phrase, then ‘being desired’ cannot fulfil this function, for there are other objects of desire besides τό άγαθόν.

Addresses Bedford’s attack on appeals to introspection in the identification of emotions, which lead him to raise the question of how to draw the line between genuine and pretended anger. Austin demonstrates, through a close examination of the speech acts of ‘pretending’ and ‘really being’, that none of the supposed conditional relations between these two notions actually holds. The essay further introduces Austin’s distinction between ‘pretending to do’ and ‘pretending to be’ and emphasises the complex and diverse forms speech acts (...) involving ‘pretending’ can take. (shrink)

Concerned with the question of whether descriptions of identity, i.e. describing X as Y, amount to the same as statements of identity, i.e. stating that X equals Y. Austin characteristically tackles this question by investigating into the nature of a number of relevant speech acts, such as ‘calling’, ‘describing’, and ‘stating’. He concludes negatively that none of the speech acts discussed can be safely used in philosophy in a general way. However, the construction of models of speech situations reveals their (...) underlying complexity: such models are plainly too complicated to accommodate the standard subject-predicate or class-membership models that a straightforward answer to the question raised in this paper would depend on. (shrink)

Picks up on a previous discussion of responsibility, freedom, and excuses, in which Austin argues that, in order to discover whether someone acted freely, we must discover whether certain excuses relevant to the situation at hand are acceptable. The notion of freedom, according to this view, is intractably linked to the notion of responsibility. Chapter 12 refines the previous discussion, by illuminating the differences between the notions of purpose, intention, and deliberation in a variety of speech acts.

‘Unfair to Facts’ is a follow-up on Ch. 5, addressing objections Peter Strawson raised against Austin’s view of truth as a description of the conditions that must be satisfied if we are to say of a statement that it is true. Austin addresses the objection that his description of these conditions is due to a misunderstanding about the use of ‘fact’, arguing, against Strawson, that facts are not pseudo-entities and that the notion of ‘fitting the facts’ is not a useless (...) notion.

‘The Meaning of a Word’ is a polemic against the view that philosophy can be done by way of pinning down the meaning of words used in philosophising. Its argument is threefold: the first part argues that ‘the meaning of a word’ is, in general, if not always, a dangerous nonsensephrase, in the sense that there is no simple and handy appendage of a word called ‘the meaning of “x”’. The second part applies this conclusion to problems that rely on (...) the assumption that phrases like ‘the meaning of a word’ or ‘part of the meaning of the word’ are not completely undefined, proposing that we are using a working-model for philosophical problems which fails to fit the facts that we really wish to talk about. The third part addresses the problem of universals, which, according to Austin, boils down to the question of why we call different things, say two chairs in your living room, by the same name, that is, ‘chair’. Austin examines the phrase ‘having the same meaning’ in order to reveal the different reasons we have for calling different things by the same name. (shrink)

A reconstruction based on previously unpublished notes, of Austin’s views of the Line and Cave allegories in Plato’s Republic. In these drafts, Austin discusses the prominent issues that arise in the context of Plato’s Line allegory, e.g. the questions of division and continuity, and shows how the different stages in the Cave allegory correspond to individual sections of the Line.

A Dirac-like equation for a massive field obeying the classical Proca equations of motion (PMO) is proposed in close analogy with Majorana’s construct for Maxwell electrodynamics. Its underlying algebraic structure is examined and a plausible physical interpretation is discussed. The behavior of the PMO equations in the presence of an external electromagnetic field is also investigated in the low energy limit, via unitary transformations similar to the Foldy-Wouthuysen canonical transformation for a Dirac fermion.

A cross-sectional study to ascertain what the Singapore population would regard as material risk in the anaesthesia consent-taking process and identify demographic factors that predict patient preferences in medical decision-making to tailor a more patient-centered informed consent. A survey was performed involving patients 21 years old and above who attended the pre-operative evaluation clinic over a 1-month period in Singapore General Hospital. Questionnaires were administered to assess patients’ perception of material risks, by trained interviewers. Patients’ demographics were obtained. Mann–Whitney U (...) test and Kruskal-Wallis one-way analysis of variance was used. Statistical significance was taken at p < 0.05. Four hundred fourteen patients were eligible of which 26 refused to participate and 24 were excluded due to language barrier. 364 patients were recruited. A higher level of education, being employed and younger age group are factors identified in patients who wanted greater participation in medical decisions. Gender, marital status, type of surgery, and previous surgical history did not affect their level of participation. The complications most patients knew about were Nausea, Drowsiness and Surgical Wound Pain. Patients ranked Heart Attack, Death and Stroke as the most significant risks that they wanted to be informed about in greater detail. Most patients wanted to make a joint decision with the anaesthetist, instead of letting the doctor decide or deciding for themselves. Discussion with the anaesthetist is the preferred medium of communication compared to reading a pamphlet or watching a video. Age and educational level can influence medical decision-making. Despite the digital age, most patients still prefer a clinic consult instead of audio-visual multimedia for pre-operative anaesthetic counselling. The local population appears to place greater importance on rare but serious complications compared to common complications. This illustrates the need to contextualize information provided during informed consent to strengthen the doctor-patient relationship. (shrink)

It is always possible to construct a real function f, given random quantities X and Y with continuous distribution functions F and G, respectively, in such a way that f(X) and f(Y), also random quantities, have both the same distribution function, say H. This result of De Finetti introduces an alternative way to somehow describe the `opinion' of a group of experts about a continuous random quantity by the construction of Fields of coincidence of opinions (FCO). A Field of coincidence (...) of opinions is a finite union of intervals where the opinions of the experts coincide with respect to that quantity of interest. We speculate on (dis)advantages of Fields of Opinion compared to usual `probability' measures of a group and on their relation with a continuous version of the well-known Allais' paradox. (shrink)
