Recent advances in philosophical thinking about consciousness, such as cognitive phenomenology and mereological analysis, provide a framework that facilitates using computational models to explore issues surrounding the nature of consciousness. Here we suggest that, in particular, studying the computational mechanisms of working memory and its cognitive control is highly likely to identify computational correlates of consciousness and thereby lead to a deeper understanding of the nature of consciousness. We describe our recent computational models of human working memory and propose that (...) three computational correlates of consciousness follow from the results of this work: itinerant attractor sequences, top-down gating, and very fast weight changes. Our current investigation is focused on evaluating whether these three correlates are sufficient to create more complex working memory models that encompass compositionality and basic causal inference. We conclude that computational models of working memory are likely to be a fruitful approach to advancing our understanding of consciousness in general and in determining the long-term potential for development of an artificial consciousness specifically.

While substantial progress has been made in the field known as artificial consciousness, at the present time there is no generally accepted phenomenally conscious machine, nor even a clear route to how one might be produced should we decide to try. Here, we take the position that, from our computer science perspective, a major reason for this is a computational explanatory gap: our inability to understand/explain the implementation of high-level cognitive algorithms in terms of neurocomputational processing. We explain how addressing (...) the computational explanatory gap can identify computational correlates of consciousness. We suggest that bridging this gap is not only critical to further progress in the area of machine consciousness, but would also inform the search for neurobiological correlates of consciousness and would, with high probability, contribute to demystifying the “hard problem” of understanding the mind–brain relationship. We compile a listing of previously proposed computational correlates of consciousness and, based on the results of recent computational modeling, suggest that the gating mechanisms associated with top-down cognitive control of working memory should be added to this list. We conclude that developing neurocognitive architectures that contribute to bridging the computational explanatory gap provides a credible and achievable roadmap to understanding the ultimate prospects for a conscious machine, and to a better understanding of the mind–brain problem in general.

Recent computer simulations of evolving neural networks have shown that population-level behavioral asymmetries can arise without social interactions. Although these models are quite limited at present, they support the hypothesis that social pressures can be sufficient but are not necessary for population lateralization to occur, and they provide a framework for further theoretical investigation of this issue.

Previous simulation work on the evolution of communication has not shown how a large signal repertoire could emerge in situated agents. We present an artificial life simulation of agents, situated in a two-dimensional world, that must search for other agents with whom they can trade resources. With strong restrictions on which resources can be traded for others, initially non-communicating agents evolve/learn a signal system that describes the resource they seek and the resource they are willing to offer in return. A (...) large signal repertoire emerges mainly through an evolutionary process. Agents whose production and comprehension abilities rely on a single mechanism fare best, although learning enables agents with separate mechanisms to achieve some measure of success. These results demonstrate that substantial signaling repertoires can evolve in situated multi-agent systems, and suggest that simulated social interactions such as trading may provide a useful context for further computational studies of the evolution of communication.

After reconstructing three arguments for Nietzsche’s descriptive analysis of the self as complex, this article clarifies some of greatness’s psychological conditions. It then offers three arguments for why we should not focus on these internal conditions when seeking to verify or to achieve greatness. First, Nietzsche’s descriptive analysis of the self renders introspection too coarse-grained and error-prone to verify the subtle type of unity required for greatness. Second, Nietzsche associates introspective appraisal of one’s psyche with a moral project that weakens (...) and represses the drives, such that inquiry into whether greatness’s internal conditions are satisfied typically speaks against their realization. Finally, the actions characteristic of Nietzsche’s great individuals prohibit introspective preoccupation with oneself. These arguments suggest that we should attend to outwardly directed accomplishments, rather than psychology, when appraising the greatness of others and seeking to become great ourselves. (shrink)

We are immersed within an odorous sea of chemical currents that we parse into individual odors with complex structures. Odors have been posited as determined by the structural relation between the molecules that compose the chemical compounds and their interactions with the receptor site. But, naturally occurring smells are parsed from gaseous odor plumes. To give a comprehensive account of the nature of odors the chemosciences must account for these large distributed entities as well. We offer a focused review of (...) what is known about the perception of odor plumes for olfactory navigation and tracking, which we then connect to what is known about the role odorants play as properties of the plume in determining odor identity with respect to odor quality. We end by motivating our central claim that more research needs to be conducted on the role that odorants play within the odor plume in determining odor identity. (shrink)

Paul Sagar's invigorating book is a reconsideration of Adam Smith in the sense that it challenges much that is received wisdom in current scholarship. First and foremost, it rejects the idea that Smith was preeminently a moral philosopher concerned with the threat to civic virtue posed by commercial society, and yet intent on giving commercial society a moral vindication nevertheless. Sagar—rightly, in my view—wants us to recognize Smith as having been a political thinker. Too much work on Smith still assumes (...) that there is not much to say about his political thought because he regarded all but the most minimal government as an obstacle to the proper functioning of markets. Smith is supposed to be a "classical... Read More. (shrink)

This summary account of Hume’s life and works challenges the usual way of telling the story of Hume’s career. It is generally believed that what Hume most wanted to be was a philosopher and that Hume turned to politics and history because that desire was frustrated, principally by the reputation for atheism he had acquired as a result of his writings on religion. The author argues that, from the beginning, Hume was as interested in politics as he was in philosophy; (...) that a career as an independent man of letters, and not as a professional philosopher, was what he most wanted; and that that career was a success, with the History of England its triumphant culmination. Hume’s religious skepticism was no obstacle to his living the life that he most wanted to live, the life of a sophisticated and widely respected citizen of the European republic of letters. (shrink)

What big questions and large‐scale narratives give coherence to the history of science? From the late 1970s onward, the field has been transformed through a stress on practice and fresh perspectives from gender studies, the sociology of knowledge, and work on a greatly expanded range of practitioners and cultures. Yet these developments, although long overdue and clearly beneficial, have been accompanied by fragmentation and loss of direction. This essay suggests that the narrative frameworks used by historians of science need to (...) come to terms with diversity by understanding science as a form of communication. The centrality of processes of movement, translation, and transmission is already emerging in studies of topics ranging from ethnographic encounters to the history of reading. Not only does this approach offer opportunities for crossing boundaries of nation, period, and discipline that are all too easily taken for granted; it also has the potential for creating a more effective dialogue with other historians and the wider public.

Despite Plato's various warnings not to do so, his dialogues have been studied as systematic philosophy since antiquity. In this innovative and controversial reassessment, James Arieti argues that they should be read primarily as works of drama rather than philosophical discourse. Analyses of 18 of the 28 dialogues allow the reader to see them as integrated dramas, with all the ambiguities and uncertainties that literary works contain. As in plays generally, the arguments of particular characters cannot be seen as (...) the opinions of the author, whose views emerge only from examining each work as a whole. This literary reading shows how much of the debate about Plato's meaning has been misplaced. Instead of demonstrating that an argument is fallacious or valid, we need to ask why Plato has the particular character make the argument. Interpreting Plato achieves what no other work on Plato has attempted: to see the philosophical arguments as serving a dramatic purpose. (shrink)

Abstract:This paper is an analysis of Plato's use of the embassy to Achilles in Homer's Iliad book 9 as a literary template for Crito's mission to persuade Socrates to escape from prison in Athens. Plato's purpose is to elevate the nature of a hero by contrasting the impulsive, impetuous, mercurial temper of Achilles with the steady, thoughtful, deliberative, calmly rational argument of Socrates. Plato shows, in a volley fired at the poet, how the philosopher is more meaningfully heroic than the (...) warrior, for where the warrior aims selfishly at securing his own honor, the philosopher aims at political virtue.

Since its introduction in 1987, Benjamin Freedman’s principle of clinical equipoise has enjoyed widespread uptake in bioethics discourse. Recent years, however, have witnessed a growing consensus that the principle is fundamentally flawed. One of the most vocal critics has undoubtedly been Franklin Miller. In a 2008 paper, Steven Joffe and Miller build on this critical work, offering a new conception of clinical research ethics based on science, taking what they call a “scientific orientation” toward the ethics of clinical research. Though (...) there is much to recommend Joffe and Miller’s scientifically oriented conception of clinical research ethics, I believe that both the critical and constructive projects suffer from the same basic mistake: inattention to context. The internal norms of science cannot be fully specified, let alone satisfied, independently of contextual (external) factors that only come into view when we are attentive to the particular context of that form of inquiry.

(1) Substituting (as Solms does) forebrain for brainstem in the search for a dream “controller” is counterproductive, since a distributed system need have no single controller. (2) Evidence against episodic memory consolidation does not show that REM sleep has no role in other types of memory, contra Vertes & Eastman. (3) A generalization of Revonsuo's “threat simulation” model in reverse is more plausible and is empirically testable. [Hobson et al.; Solms; Revonsuo; Vertes & Eastman].

This book explores how the Hebraic and classical traditions forming our Western heritage combined from about 300 BCE to 300 CE. James Arieti investigates the principal causes of the merger in the common model of God that developed in the Greek philosophical schools, along with its ethical implications, and the shared portrayal in biblical, rabbinic, and postclassical literature of the compassionate warm character that we recognize as a mentsh.

Competing perspectives on the nature of emotion are illustrated with latent and emergent variable models. Latent variable models draw from classical test theory, assuming that the measured indicators of emotion covary by virtue of some common executive, organizing neural circuit or network in the brain. By contrast, emergent variable models draw from a theory-driven, operational definition tradition, positing that emotions do not cause, but rather are caused by, the measured indicators of emotion, assuming no executive neural circuit or network, and (...) requiring no covariation among indicators. I suggest that the emergent variable model may be more compatible with the extant literature on the nature of emotion, especially in the age of affective neuroscience. (shrink)

Despite their crucial role in the translation of pre-clinical research into new clinical applications, phase 1 trials involving patients continue to prompt ethical debate. At the heart of the controversy is the question of whether risks of administering experimental drugs are therapeutically justified. We suggest that prior attempts to address this question have been muddled, in part because it cannot be answered adequately without first attending to the way labor is divided in managing risk in clinical trials. In what follows, (...) we approach the question of therapeutic justification for phase 1 trials from the viewpoint of five different stakeholders: the drug regulatory authority, the IRB, the clinical investigator, the referring physician, and the patient. Our analysis shows that the question of therapeutic justification actually raises multiple questions corresponding to the roles and responsibilities of the different stakeholders involved. By attending to these contextual differences, we provide more coherent guidance for the ethical negotiation of risk in phase 1 trials involving patients. We close by discussing the implications of our argument for various perennial controversies in phase 1 trial practice. (shrink)

In this paper we explain our pretense account of truth-talk and apply it in a diagnosis and treatment of the Liar Paradox. We begin by assuming that some form of deflationism is the correct approach to the topic of truth. We then briefly motivate the idea that all T-deflationists should endorse a fictionalist view of truth-talk, and, after distinguishing pretense-involving fictionalism (PIF) from error- theoretic fictionalism (ETF), explain the merits of the former over the latter. After presenting the basic framework (...) of our PIF account of truth-talk, we demonstrate a few advantages it offers over T-deflationist accounts that do not explicitly acknowledge pretense at work in the discourse. In turning to the Liar Paradox, we explain how the quasi-anaphoric functioning that our account attributes to truth-talk provides a diagnosis of the Liar Paradox (and other instances of semantic pathology) as having no content—in the sense of not specifying any of what we call M-conditions. At the same time, however, we vindicate the intuition that we can understand liar sentences, thereby avoiding one standard objection to “meaningless strategy” responses to the Liar Paradox. With this diagnosis in place, we then, by way of treatment, introduce a new predicate, ‘semantically defective’, and show how the explanation we give for its application allows for a consistent, yet revenge-immune, (dis)solution of the Liar Paradox, and semantic pathology generally.

Discourses on the First Book of Herodotus is an important work for historians, classicists, and philosophers. (shrink)

Papers presented at a conference held at the James A. Baker III Institute for Public Policy at Rice University, in Apr. 2006.

In this book, Bradley Armour-Garb and James A. Woodbridge distinguish various species of fictionalism, locating and defending their own version of philosophical fictionalism. Addressing semantic and philosophical puzzles that arise from ordinary language, they consider such issues as the problem of non-being, plural identity claims, mental-attitude ascriptions, meaning attributions, and truth-talk. They consider 'deflationism about truth', explaining why deflationists should be fictionalists, and show how their philosophical fictionalist account of truth-talk underwrites a dissolution of the Liar Paradox and its (...) kin. They further explore the semantic notions of reference and predicate-satisfaction, showing how philosophical fictionalism can also resolve puzzles that these notions appear to present. Their critical examination of fictionalist approaches in philosophy, together with the development and application of their own brand of philosophical fictionalism, will be of great interest to scholars and upper-level students of philosophy of language, metaphysics, philosophical logic, philosophy of mind, epistemology, and linguistics.
