We would like to thank Dolega and Dewhurst for a thought-provoking and informed deconstruction of our article, which we take as applause from valued members of our audience. In brief, we fully concur with the theatre-free formulation offered by Dolega and Dewhurst and take the opportunity to explain why we used the Cartesian theatre metaphor. We do this by drawing an analogy between consciousness and evolution. This analogy is used to emphasize the circular causality inherent in the free energy principle. (...) We conclude with a comment on the special forms of active inference that may be associated with selfawareness and how they may be especially informed by dream states. (shrink)

Cognitive science is experiencing a pragmatic turn away from the traditional representation-centered framework toward a view that focuses on understanding cognition as "enactive." This enactive view holds that cognition does not produce models of the world but rather subserves action as it is grounded in sensorimotor skills. In this volume, experts from cognitive science, neuroscience, psychology, robotics, and philosophy of mind assess the foundations and implications of a novel action-oriented view of cognition. Their contributions and supporting experimental evidence show that (...) an enactive approach to cognitive science enables strong conceptual advances, and the chapters explore key concepts for this new model of cognition. The contributors discuss the implications of an enactive approach for cognitive development; action-oriented models of cognitive processing; action-oriented understandings of consciousness and experience; and the accompanying paradigm shifts in the fields of philosophy, brain science, robotics, and psychology.

This paper presents a version of neurophenomenology based on generative modelling techniques developed in computational neuroscience and biology. Our approach can be described as _computational phenomenology_ because it applies methods originally developed in computational modelling to provide a formal model of the descriptions of lived experience in the phenomenological tradition of philosophy (e.g., the work of Edmund Husserl, Maurice Merleau-Ponty, etc.). The first section presents a brief review of the overall project to naturalize phenomenology. The second section presents and evaluates (...) philosophical objections to that project and situates our version of computational phenomenology with respect to these projects. The third section reviews the generative modelling framework. The final section presents our approach in detail. We conclude by discussing how our approach differs from previous attempts to use generative modelling to help understand consciousness. In summary, we describe a version of computational phenomenology which uses generative modelling to construct a computational model of the inferential or interpretive processes that best explain this or that kind of lived experience.

This study aimed to investigate whether a range of tasks that have been generally classed as requiring insight form an empirically separable group of tasks distinct from tasks generally classed as non-insight. In this study, 24 insight tasks, 10 non-insight tasks, and tests of individual differences in cognitive abilities and working memory were administered to 60 participants. Cluster analysis of the problem-solving tasks indicated that the presumed insight problems did tend to cluster with other presumed insight problems, and similarly the (...) presumed non-insight problems tended to cluster with other presumed non-insight tasks. Performance on presumed insight problems was particularly linked to measures of ideational flexibility with a different pattern of results for the non-insight tasks. Spatial insight problems were linked to spatial flexibility and verbal insight tasks were linked to vocabulary scores. The results are discussed in relation to recent developments of dual process theories of thinking. (shrink)

In recent years there has been an upsurge of research aimed at removing the mystery from insight and creative problem solving. The present special issue reflects this expanding field. Overall the papers gathered here converge on a nuanced view of insight and creative thinking as arising from multiple processes that can yield surprising solutions through a mixture of “special” Type 1 processes and “routine” Type 2 processes.

Two firm points in the chronology of Antiphon's speeches are VI περ το χορευτο in 419/81 and the Defence in 411/02. Speech V περ τσ 'Hρδου is now generally dated between these two; only the vaguest attempts have been made to date I κατ τσ μητρυασ; there is no general agreement on either the date or the authorship of the Tetralogies. The main purpose of this paper is to adduce linguistic as well as external evidence for the dating of V (...) in the neighbourhood of 414 and to show grounds for dating I between VI and V. Its secondary purpose is to apply some of the results gained in this inquiry to the fragments and the Tetralogies. (shrink)

Viewing the brain as an organ of approximate Bayesian inference can help us understand how it represents the self. We suggest that inferred representations of the self have a normative function: to predict and optimise the likely outcomes of social interactions. Technically, we cast this predict-and-optimise as maximising the chance of favourable outcomes through active inference. Here the utility of outcomes can be conceptualised as prior beliefs about final states. Actions based on interpersonal representations can therefore be understood as minimising (...) surprise – under the prior belief that one will end up in states with high utility. Interpersonal representations thus serve to render interactions more predictable, while the affective valence of interpersonal inference renders self-perception evaluative. Distortions of self-representation contribute to major psychiatric disorders such as depression, personality disorder and paranoia. The approach we review may therefore operationalise the study of interpersonal representations in pathological states. (shrink)

The integrated information theory is a promising theory of consciousness. However, there are several problems with IIT's axioms and postulates. Moreover, IIT entails that some twodimensional grids of identical logic gates have more consciousness than humans. Many have found this prediction to be implausible, and as will be argued here, this prediction also exacerbates the so-called 'hard problem of consciousness'. Recently, it has been argued that if we treat the phenomenological aspects of consciousness as an illusion, we can avoid the (...) hard problem altogether by replacing it with the more tractable illusion problem: the problem of explaining how introspection systematically misrepresents experiences as having phenomenology. IIT is intended to be a theory of the phenomenological aspects of consciousness. However, it is possible to reformulate the axioms and postulates of IIT consistently with illusionism. Here it is argued that the resulting theory -- illusionist integrated information theory -- removes several problems for IIT including the hard problem and the logic gate problem, and also enables meaningful progress for illusionists on solving the illusion problem.

The present study investigated the role of thought suppression in incubation, using a delayed incubation paradigm. A total of 301 participants were tested over five conditions, viz., continuous work control, incubation with a mental rotations interpolated task, focussed suppression, unfocussed suppression and a conscious expression condition. Checks were made for intermittent work during the incubation condition. The target task was alternative uses for a brick. In the incubation and suppression conditions, participants worked for 4 minutes, then had a break during (...) which suppression or the mental rotations interpolated task was carried out for 3 minutes before conscious work was resumed for a further 4 minutes on the alternative uses task. Results indicated that both incubation with an interpolated distractor task and incubation with suppression were effective in enhancing performance relative to controls. The intermittent work hypothesis (that effects of an incubation period are simply due to illicit con.. (shrink)

This paper reports a study of planning processes in the five-disc Tower of London (TOL) task in 20 younger and 20 older adult participants. A concurrent direct ''think-aloud'' method was used to obtain data on planning processes prior to moving discs in the TOL. A check was made of the effects of verbalising by comparing performance data from the experimental groups with data from control groups who did not verbalise during planning or moving. Verbalising slowed down planning and moving but (...) did not appear to distort the participants' approaches to the task. Older and younger participants did not differ in average moves taken to solve the tasks. However, older participants' planning was less complete and more error-prone than that of younger participants. The planning processes were characterised as showing a means-ends ''goal selection'' strategy. In this strategy participants (1) identify a single active goal disc at the start, (2) select moves and move sequences to enable the placing of the current goal disc in its target position, and (3) continue in this way until all discs are in their target positions. Age differences were found in the planning stage, during which there was no stimulus support and hence a substantial working memory load. During the move phase there was stimulus support and hence little loading of working memory. Age differences in moves required were not found in the move phase. As older participants tend to have depleted working memory capacity the present results suggest that working memory is heavily loaded in TOL planning but less so in the move phase of TOL. (shrink)

In ‘The nature of moral judgments and the extent of the moral domain’, Fraser criticises findings by Kelly et al. that speak against the moral/conventional distinction, arguing that the experiment was confounded. First, we note that the results of that experiment held up when confounds were removed . Second, and more importantly, we argue that attempts to prove the existence of a M/C distinction are systematically confounded. In contrast to Fraser, we refer to data that support our view. We highlight (...) the implications for the moral/conventional theory. (shrink)

This historical survey of Greek literature from 700 BC to 550 AD concentrates on the principal authors and quotes many passages from their work in translation, to allow the reader to form his own impression of its quality, including Homer, Plato, Aristophanes, and Euripides. Attention is drawn both to the elements in Greek literature and attitudes to life which are unfamiliar to us, and to the elements which appeal most powerfully to succeeding generations. Although it is recognized that this appeal (...) lies above all in the most creative and inventive period, an account is given of the eight hundred years which followed, which saw the impact of earlier inspirations. Poetry, tragedy, comedy, history, science, philosophy, and oratory are all examined through the available literature. This new edition has been revised to take account of recent scholarship, such as the influence of oriental traditions of Greek literature, and includes several new translations and a thoroughly updated bibliography.

On the analogy of the colloquial register in some modern languages, where narrative and argument may be punctuated by oaths and exclamations in order to maintain a high affective level and compel the hearer's attention, it is reasonable to postulate that Attic conversation also was punctuated by oaths, that this ingredient in comic language was drawn from life, and that the comparative frequency of ║ M M Δ in comedy is sufficiently explained thereby. There are obvious affinities between some passages (...) of comedy, relaxed conversation in Plato and Xenophon, and the forceful, man-to-man tone which Demosthenes sometimes adopts to such good effect . Compare, for instance, Ar. V. 133 f. στιν δ' νομα ⋮ τ μν γέροντι ⋮ Φιλοκλέων / να μ Δία, τ δ' υε κτλ., where the oath is a response to imagined incredulity, and X. Smp. 4.27 ατν δ σέ, η, γ εδον να μ τν πόλλω, τε κτλ. . It is also important that the commonest oaths fit, in most of their forms, the end of an iambic trimeter: μ τν Δία, ν Δία,ν τούς θεούς, μ τος θεούς. Add that in Aristophanic dialogue over half the iambic trimeters end with major pause, and half the remainder with minor pause, and we can see why Δ / established itself early as a distinctive comic pattern. Out of 105 examples of M M Δ cited from comedy in Section II above, 59 have the oath at verse-end. In the case of πάνυ, which was almost exclusively Attic and — to judge from its great rarity in tragedy — felt by Athenian poets to be prosaic, we lack evidence on its functions in the colloquial register; it may or may not have served as affective punctuation. In prose, we have to reckon with the fact that π Mπ and Mπ π constituted a genuine stylistic choice as far back as the evidence will take us, since the two earliest instances in prose are [X.] Ath. 2.3 πάνυ δι χρείαν and ibid. 3.5 πολλ τι πάνυ. The oath, as treated by the comic poets on the basis of colloquial usage, is bound to have served as a model for πάνυ, exerting an influence which pulled πάνυ to the end of the verse, but there was also a powerful metrical constraint. As a dibrach ending in a vowel which could not be elided or enter into crasis, πάνυ was especially appropriate for verse-end. That in itself was enough both to establish Mπ π as the dominant pattern in comedy and to promote Mπ … π. Out of the total of 104 examples of Mπ π in comedy, 93 have πάνυ at verse-end, which makes Mπ π / one of the hallmarks of comic style. Mπ … π does not occur in prose in association with any other feature identified as colloquial, but it should be noted that Aiskhines and Demosthenes are much fonder of Mπ π than other prose authors. In some cases one can see that the order Mπ π avoids a succession of short syllables or hiatus or both , but there are other cases in which it has the opposite effect . The possibility of comic influence on oratorical language cannot be dismissed out of hand. It is also possible that someone will find positive determinants which will explain all the cases of Mπ π in prose. σόδρα, which, like πάνυ, is peculiarly Attic, is metrically more tractable than πάνυ, since it can be elided; even so, out of the 80 comic examples of Mσ σ no less than 58 have σόδρα at verse-end, and of those 58 there are 22 at major pause, 8 at presumed major pause and 9 at minor pause. The comic treatment of σόδρα is thus comparable with the treatment of πάνυ, and Timokles 222.4 τηρεν…σόδρα is in fact the closest analogy we have to Ar. Pl. 234 f. χθομαι…πάνυ. δέ and γάρ are a different matter, and in some significant respects different from each other. Postponement of δέ is especially prominent in Aeschylus and then abundant in fourth-century comedy. It is much less common in Euripides , rare in Sophocles and Aristophanes , and virtually limited in prose to the categories which I labelled –. There is as yet no evidence to associate postponement of δέ with colloquial language; on the contrary, it seems to have begun as a feature of poetic language and to have been taken up and exploited by fourth-century comedy. If, in addition to being Aeschylean, it was colloquial in the fourth century, what happened to it afterwards? Except for such an isolated and inexplicable case as Diod. xx85.1 — in a military narrative — it is not a feature of the Koine at literary, documentary or subliterate level. Postponement of γάρ was no doubt encouraged by postponement of δέ, but it is not itself notably poetic ). One can see how it could possibly have developed in the spoken language of the fourth century, extending the function of γάρ as an explanatory particle in a way which makes it comparable with the English ‘you see’ in ‘He didn't dare pick it up. He hurt his back last year, you see’. For an extension of this kind we may compare the current extension of the English genitive affix in ‘Then the girl whose place she was taking's mother turned up’ and ‘The man that Christopher liked's Introduction is much better’. Moreover, postponed γάρ appears in a segment of conversation constructed in indirect speech by Theophrastus in Char. 8.9 τ πργμα βοσθαι γάρ . Again we must ask: what happened to it afterwards? A couple of cases in Theophrastus' botanical works could be a reflex of the influence of comedy on literary language at Athens. The influence was plainly short-lived, since it did not affect the Koine. It is not hard to see why serious poetry in the fifth century and earlier should have experimented occasionally with the postponement of δέ and γάρ: treatment of M M q as a valid alternative to M q M is metrically very convenient. No poet, however, could afford to use common words in a bizarre, un-Greek way merely to save himself time and trouble in constructing a verse. Linguistic innovation is normally analogical, proceeding by extension from a starting-point already there, and the most obvious starting-point for postponement of δέ and γάρ is constituted by my class . This consideration provides comic postponement with a pedigree, but does not deny it individuality. The remarkable scale and frequency with which comedy exploited a phenomenon which tragedy used with restraint and prose hardly at all gives comic postponement the right to be regarded as a quite distinctive artificial feature of comedy.

On the analogy of the colloquial register in some modern languages, where narrative and argument may be punctuated by oaths and exclamations (sometimes obscene or blasphemous) in order to maintain a high affective level and compel the hearer's attention, it is reasonable to postulate that Attic conversation also was punctuated by oaths, that this ingredient in comic language was drawn from life, and that the comparative frequency of ║ (|)M M(M) Δ in comedy is sufficiently explained thereby.
