The problem of how the brain produces consciousness, subjectivity and "something it is like to be" remains one of the greatest challenges to a complete science of the natural world. While various scientists and philosophers approach the problem from their own unique perspectives and in the terms of their own respective fields, Biophysics of Consciousness: A Foundational Approach attempts a consilience across disparate disciplines to explain how it is possible that an objective brain produces subjective experience. This volume unites the (...) cr me de la cr me of physicists, neuroscientists, and psychiatrists in the attempt to understand consciousness through a foundational approach encompassing ontological, evolutionary, neurobiological, and Freudian interpretations with the focus on conscious phenomena occurring in the brain. By integrating the perspectives of these diverse disciplines with the latest research and theories on the biophysics of the brain, the book tries to explain how what John Searle calls a "conscious field" can be an adaptive and causal element in the natural world.

In this paper we investigate a number of analytical solutions to the polynomial class of nonlinear Klein-Gordon equations in multidimensional spacetime. This is done in the context of classical φ4 and φ6 field theory, the former with and without the inclusion of an external force field conjugate to φ. Both massive (m≠0) and massless (m=0) cases are considered, as well as tachyonic solutions allowed (v>c). We first present a complete set of translationally invariant solutions for the φ4 model and demonstrate (...) the role of external force fields in altering the form of these solutions. Next, spherically symmetric solutions are discussed in both φ4 and φ6 cases since they provide the most realistic models of elementary particles. (shrink)

If the physical mind is located in quantized space of the brain then how does the physical mind become the self? This remains an unresolved problem. It can be restated as how mental representations or mental states get their informational contents, and of doing so in terms of the natural functions brain states have? We call these natural brain functions not teleosemantic functions, but rather teleological functions. This is because teleosemantics portrays mental representations which must have informational contents that track (...) “operational explanations of cognitive capacities” while teleological functions do not as they are hidden in quantized space, suggesting that mind is physical. Specifically teleonomic capacities have been built into us by natural selection, which naturally leads to a teleogical notion of function. Our claim is that teleofunctionality as unification of mental states has natural functions that carry intrinsic dispositions that may be broadly defined as ‘subjectivity’ or intrinsic information content of mental states. Mental states have intrinsic dispositions to change their functions, producing correspondences to the world that includes further layers of subtlety hidden in quantized space. How does intrinsic information self-replicate content in cases of mental misrepresentation? The putative special virtue of teleosemantics and its ability to give a theory of error through ‘uncertainty’ is discussed based on a teleological functionalist epistemology. (shrink)

Much of the progress in the fields constituting cognitive science has been based upon the use of explicit information processing models, almost exclusively patterned after conventional serial computers. An extension of these ideas to massively parallel, connectionist models appears to offer a number of advantages. After a preliminary discussion, this paper introduces a general connectionist model and considers how it might be used in cognitive science. Among the issues addressed are: stability and noise‐sensitivity, distributed decision‐making, time and sequence problems, and (...) the representation of complex concepts. (shrink)

Some philosophers hold that philosophy is what you do to a problem until it’s clear enough to solve it by doing science. Others hold that if a philosophical problem succumbs to empirical methods, that shows it wasn’t really philosophical to begin with. Either way, the facts seem clear enough: questions first mooted by philosophers are sometimes coopted by people who do experiments. This seems to be happening now to the question: “what are propositional attitudes?” and cognitive psychology is the science (...) of note. (shrink)

I aim to show how and why some definitions can be benignly circular. According to Lloyd Humberstone, a definition that is analytically circular need not be inferentially circular and so might serve to illuminate the application-conditions for a concept. I begin by tidying up some problems with Humberstone's account. I then show that circular definitions of a kind commonly thought to be benign have inferentially circular truth-conditions and so are malign by Humberstone's test. But his test is too demanding. The (...) inferences we actually use to establish the applicability of, e.g., colour concepts are designed to establish warranted assertability and not truth. Understood thus, dispositional analyses are not inferentially circular. (shrink)

In this paper we attempt to sharpen and to provide an answer to the question of when human beings first become conscious. Since it is relatively uncontentious that a capacity for raw sensation precedes and underpins all more sophisticated mental capacities, our question is tantamount to asking when human beings first have experiences with sensational content. Two interconnected features of our argument are crucial. First, we argue that experiences with sensational content are supervenient on facts about electrical activity in the (...) cerebral cortex which can be ascertained through EEG readings. Second, we isolate from other notions of a‘functioning brain’that which is required to underpin the view that a cortex is functioning in a way which could give rise to rudimentary conscious experiences. We investigate the development in the human fetus of the anatomical and chemical pathways which underpin cortical activity and the growth and maturation of the electrical circuitry specifically associated with sensational content in adult experience. We conclude that a fetus becomes conscious at about 30 to 35 weeks after conception; an answer based on a careful analysis of EEG readings at various stages of cortical development. Finally, we survey the possible ethical ramifications of our answer. (shrink)

The classical Feferman–Vaught Theorem for First Order Logic explains how to compute the truth value of a first order sentence in a generalized product of first order structures by reducing this computation to the computation of truth values of other first order sentences in the factors and evaluation of a monadic second order sentence in the index structure. This technique was later extended by Läuchli, Shelah and Gurevich to monadic second order logic. The technique has wide applications in decidability and (...) definability theory. Here we give a unified presentation, including some new results, of how to use the Feferman–Vaught Theorem, and some new variations thereof, algorithmically in the case of Monadic Second Order Logic MSOL . We then extend the technique to graph polynomials where the range of the summation of the monomials is definable in MSOL . Here the Feferman–Vaught Theorem for these polynomials generalizes well known splitting theorems for graph polynomials. Again, these can be used algorithmically. Finally, we discuss extensions of MSOL for which the Feferman–Vaught Theorem holds as well. (shrink)

We investigate the expressive power of second-order logic over finite structures, when two limitations are imposed. Let SAA ) be the set of second-order formulas such that the arity of the relation variables is bounded by k and the number of alternations of second-order quantification is bounded by n . We show that this imposes a proper hierarchy on second-order logic, i.e. for every k , n there are problems not definable in AA but definable in AA for some c (...) 1 , d 1 . The method to show this is to introduce the set AUTOSAT of formulas in F which satisfy themselves. We study the complexity of this set for various fragments of second-order loeic. For first-order logic FOL with unbounded alternation of quantifiers AUTOSAT is PSpace complete. For first-order logic FOL n with alternation of quantifiers bounded by n , AUTOSAT is definable in AA . AUTOSAT) is definable in AA for some c 1 , d 1. (shrink)

Disrupting Journalism Ethics sets out to disrupt and change how we think about journalism and its ethics. The book contends that long-established ways of thinking, which have come down to us from the history of journalism, need radical conceptual reform, with alternate conceptions of the role of journalism and fresh principles to evaluate practice. Through a series of disruptions, the book undermines the traditional principles of journalistic neutrality and "just the facts" reporting. It proposes an alternate philosophy of journalism as (...) engagement for democracy. The aim is a journalism ethic better suited to an age of digital and global media. As a philosophical pragmatist, Stephen J. A. Ward critiques traditional conceptions of accuracy, neutrality, detachment and patriotism, evaluating their capacity to respond to ethical dilemmas for journalists in the 21st century. The book proposes a holistic mindset for doing journalism ethics, a theory of journalism as advocacy for egalitarian democracy, and a global redefinition of basic journalistic norms. The book concludes by outlining the shape of a future journalism ethics, employing these alternative notions. Disrupting Journalism Ethics is an important intervention into the role of journalism today. It asks: what new role journalists should play in today's digital media world? And what new mind-set, new aims, and new standards ought jounalists to embrace? The book aims to persuade--and provoke--ethicists, journalists, students, and members of the public to disrupt and invent. (shrink)

The use of the temporal augment in narrative we have found to be purely scansional. Scansional, too, is the use of the syllabic, though this has a grammatical restriction which is of some interest; indeed, next to the maintenance of type öρovδΕ, it is the most vital fact for the whole question. The unaugmented aorist is not felt as an inflection which has been docked of its first syllable; quite the reverse, the augmented tense is treated as a compound. For (...) example, é normally stands second in its clause; and so, if the syllabic augment was still consciously regarded as what it really is—viz. an adverb in composition—we should expect to see a great unwillingness to place Be after a tense thus augmented. Our expectation is fully borne out by the text; in the whole narrative of the Iliad there are only sixteen sure examples of é standing after the syllabically augmented aorist. (shrink)

Chapter 47 contains a sentence which has been the subject of a good deal of controversy and is manifestly corrupt. In the codex it reads as follows: κα τοᾁτων πνω μαιμᾃτατον θνος Bακτριανν π βασιλα οσαν διον τπον κα 'Aλξανδρος ρμηθες π τν μερν τοᾁτων ρι τοȗ Γγγον διλθε κτλ. Attempts have been made to connect this sentence with the rulers of the Kushan dynasty. It has even been suggested that οσαν represents Kονσαν : the suggestion naturally won no acceptance, (...) but one may point out that in any case it failed to attack the real difficulty, which lies in the words διον τπον On that essential point, the views of recent editors have both varied and combined.

κάτοπτρον, which is in all the manuscripts, was emended by Canter to κάτοπτον, and this emendation, or Headlam's κατόπτην, has been received by subsequent editors. Those who read κάτοπτον have been in the habit of taking the word to mean here ‘looking down upon’, and in support of this interpretation they sometimes adduce a scholium in M, κατόψιον. This does seem to prove that the scholar, whose note is copied in our scholium, found κάτοπτον in his text. Presumably he took (...) Σαρωνικο πορθμο κάτοπτον to signify ‘descried from the Saronic gulf’, having very possibly in his mind the phrase in Euripides, Hippolytus 30, where the temple of Cypris is said to be κατόψιον γς τσδε, visible from Troezen. At least we ought not without proof to lay to his account what appears to be the solecism of regarding κάτοπτον as if it meant ‘looking down upon’. Headlam's κατόπτην has at least an active force, but I cannot find that it means ‘one who looks down upon’, if that is the sense desired; it is a ‘spy’ or an ‘inspector’. And, at the end of all discussion, when one asks what in fact is this peak or headland that ‘looks down upon the Saronic crossing’, then commentators take refuge in silence or tend to contradict one another. An emendation that nobody can be sure he understands can hardly be regarded as satisfactory. It may be feared that what has happened is this. In order to get rid of κάτοπτρον, which appeared to them devoid of meaning, editors have introduced into the text a word which does not mean what they want it to mean, and which, if it had that meaning, would still present us with a picture which no man can recognize.
