If rapid growth (rap) mutants of Escherichia coli could be obtained, these might prove a valuable contribution to fields as diverse as growth rate control, biotechnology and the regulation of the bacterial cell cycle. To obtain rap mutants, a dnaQ mutator strain was grown for four and a half days continuously in batch culture. At the end of the selection period, there was no significant change in growth rate. This result means that selecting rap mutants may require an alternative strategy (...) and a number of such alternatives are discussed. (shrink)

Top-down feedback does not benefit speech recognition; on the contrary, it can hinder it. No experimental data imply that feedback loops are required for speech recognition. Feedback is accordingly unnecessary and spoken word recognition is modular. To defend this thesis, we analyse lexical involvement in phonemic decision making. TRACE (McClelland & Elman 1986), a model with feedback from the lexicon to prelexical processes, is unable to account for all the available data on phonemic decision making. The modular Race model (Cutler (...) & Norris 1979) is likewise challenged by some recent results, however. We therefore present a new modular model of phonemic decision making, the Merge model. In Merge, information flows from prelexical processes to the lexicon without feedback. Because phonemic decisions are based on the merging of prelexical and lexical information, Merge correctly predicts lexical involvement in phonemic decisions in both words and nonwords. Computer simulations show how Merge is able to account for the data through a process of competition between lexical hypotheses. We discuss the issue of feedback in other areas of language processing and conclude that modular models are particularly well suited to the problems and constraints of speech recognition. Key Words: computational modeling; feedback; lexical processing; modularity; phonemic decisions; reading; speech recognition; word recognition. (shrink)

Although researchers studying human speech recognition (HSR) and automatic speech recognition (ASR) share a common interest in how information processing systems (human or machine) recognize spoken language, there is little communication between the two disciplines. We suggest that this lack of communication follows largely from the fact that research in these related fields has focused on the mechanics of how speech can be recognized. In Marr's (1982) terms, emphasis has been on the algorithmic and implementational levels rather than on the (...) computational level. In this article, we provide a computational-level analysis of the task of speech recognition, which reveals the close parallels between research concerned with HSR and ASR. We illustrate this relation by presenting a new computational model of human spoken-word recognition, built using techniques from the field of ASR that, in contrast to current existing models of HSR, recognizes words from real speech input.

There is a common argument form in the metaphysics of natural laws literature: a theory of natural law is attacked by offering a claim L as a law of scientific field F (physics, chemistry, biology, etc.), and from this law metaphysical implications contrary to the theory are drawn. Quite often however, L would not be regarded as a law by a scientist of F. Roberts' "measurability account of laws" offers a new and interesting way to more reliably identify the laws (...) of a field F and to eliminate the L that are not laws of F from the literature.

The central thesis of our target article is that feedback is never necessary in spoken word recognition. In this response we begin by clarifying some terminological issues that have led to a number of misunderstandings. We provide some new arguments that the feedforward model Merge is indeed more parsimonious than the interactive alternatives, and that it provides a more convincing account of the data than alternative models. Finally, we extend the arguments to deal with new issues raised by the commentators (...) such as infant speech perception and neural architecture. (shrink)

An account is given of Roy Bhaskar's conception of causal necessity in order to provide an objective measure for Williams' criticisms of critical realism. In light of this account, Williams' criticisms are found to fail. The reply finishes with an alternative, critical realist account of the ontological basis of probability.

By the turn of the nineteenth century, Jeremy Bentham was a well‐ known moral and legal reformer. Bentham's moral philosophy is often introduced as an object lesson in the failures of simplistic utilitarianism. This chapter outlines the basic elements of Bentham's political philosophy. It looks at three important and distinctive features of his utilitarian thought: his introduction of four subordinate ends to guide public morality and law, his account of “official aptitude,” and his “assumption of infallibility” argument. The chapter then (...) considers James Mill's own published comments, positive and negative, on Bentham's work. It argues that, despite some rhetorical flourishes, Mill's critical comments are carefully qualified and quite specific, and do not touch large parts of Bentham's utilitarian reform project. The chapter then articulates what Mill in fact carries over from Bentham, revealing the continuing significance of both these great utilitarian thinkers. (shrink)

This essay addresses the complexities of the Roman Catholic position on war by evaluating recent documentary evidence, attending to the contemporary challenges of terrorism and humanitarian interventions. It presents two arguments. First, attending to traditional Catholic resources for assessing war, papal criticism of recent military action, and debates about a recent shift in Catholic just war logic, this essay argues that Catholic teaching on war has undergone a repositioning in a pacifist direction. Second, it contends that recent critiques of this (...) shift in position by scholars such as George Weigel and James Turner Johnson, however, are wrong to categorize this a “functional pacifism.” Though a development from within just war theory and pacifist reasoning, the Church's new stance does not operate as a type of pacifism, allowing too many possibilities for justified armed conflict to be labeled as “functional” pacifism. The essay concludes by examining the traditional Catholic theological commitments that place limits on any movement toward pacifism, precluding even a functionally pacifist position. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Queer Defamiliarisation: Writing, Mattering, Making Strange by Helen PalmerTrevor Norris (bio)Helen Palmer, Queer Defamiliarisation: Writing, Mattering, Making Strange Edinburgh: Edinburgh University Press, 2020, 214 pp. ISBN 978-1-4744-3414-0Helen palmer is senior lecturer in English literature and creative writing at Kingston University in London and the author of Deleuze and Futurism: A Manifesto for Nonsense (2014). Her research examines queer theory, performance, literary modernism, gender, aesthetics, and feminist and (...) Afrofuturist fiction. Queer Defamiliarisation explores these ideas and also includes part of Palmer’s literary creative response to James Joyce. The project here is an inquiry into reading, thinking, writing, and pleasure and considers how language can change us when we experience the relationship between naming and the performance of identity as a material boundary: the places where our bodies, behavior, and language are subject to violence in gendered, sexualized, and racialized forms. Palmer also suggests how our own and others’ experiences of violence might be bound up with an aesthetics of linguistic and formal complexity, and she reimagines the difficulty of naming for violently excluded identities by reviewing a range of complex experimental and avant-garde literary works in which new identities can emerge. Showing us how we might understand the materiality of bodies, sense making, and desire in emancipa-tory ways, Palmer attunes us to a phenomenology of reading in which we [End Page 217] recognize how argument undergoes metamorphosis by always being a hybrid of theory, criticism, cultural history, appropriation, memoir, and experimental form. Palmer’s wide-ranging arguments speak about the porosity and mutual embeddedness of our selves, our language, our bodies and environments, and the queer processes of world creation that act on and emerge from these things. Placing her work with other texts that rethink gender, personhood and ecology through new materialisms is productive, therefore, and readers might find value in looking at Queer Defamiliarisation alongside Donna Haraway’s (2016) Staying with the Trouble, Timothy Morton’s (2019)Humankind, and Rebecca Tamás’s (2020) Strangers inasmuch as they think through the ethics and emergence of relatedness and examine what it means to play, be alongside, care for, and nurture other beings and their worlds. Palmer’s project stays with the kind of “serious and... lively” trouble that allows “unexpected collaborations and combinations, in hot compost piles” (Haraway 2016, 4).The fertile landscape is mapped out in three introductions whose themes are explored in four chapters. Palmer transforms the early-twentieth-century Russian formalist concept of defamiliarization as literary and aesthetic device, the “paradoxical process that... restores sensations to things through a [linguistic] distancing that is also a re-proximation, an approximation, a touching” (9), by reading early- to mid-twentieth-century literary and cultural theorists such as Shklovsky, Brecht, and Jakobson through the ideas of contemporary queer, feminist, and decolonial scholars such as Sara Ahmed, Rosi Braidotti, and Vicki Kirby. She questions how the estrangement of naming operates for those whose bodies are not normatively gendered, racialized, and sexualized in relation to dominant forms of representation and power and explores concerns with and for queer, trans, decolonial, and feminist aesthetics. Throughout, she encourages us to think of the strangeness of language in relation to an ethics and an erotics of radical sympathy with the stranger because it is in the “continuous movement and continual transformation” (13) of naming, and categories of naming, that an emancipatory ethics can be found. This is a timely intervention by Palmer given current anxieties around naming gender and sex, and her argument seeks to move beyond “unhelpful binaries” to acknowledge the “infinite variations and permutations of existence and experience” (14).Palmer productively combines Sara Ahmed’s concept of disorientation from Queer Phenomenology (2006) with the psycholinguistic registers of Jakobson’s “contiguity and displacement” to suggest that queer defamiliarization is a performance of language and naming that “cleaves through and between sameness and difference,” “knocking signifiers loose and ungrounding bodies,” leading to “perceptual shifts and corporeal responses” that can “materially en-gender newness” (Palmer 17). From the start of the section “Spectaxa” (152), Palmer foregrounds the materiality of her text in increasingly modernistic excess to illustrate what we have been reading and... (shrink)

This essay responds to James Turner Johnson's critiques of my argument in “‘Never Again War’: Recent Shifts in the Roman Catholic Just War Tradition and the Question of ‘Functional Pacifism.’” . It attends specifically to three of Johnson's objections and offers accounts of the meaning and use of the term “functional pacifism,” an understanding of classic just war thought as a tradition, and the concepts of peace and authority within just war and pacifist thought. It argues that my analysis (...) of the Catholic Church's movement toward pacifism but ultimate theological inability to embrace a functional pacifism still stands in spite of Johnson's critiques. In addition, it suggests that Johnson offers a thin pacifistic conception of peace and promotes a restricted notion of ecclesial authority and democratic government. (shrink)

In addition to noting significant differences of interpretation between me and Kristopher Norris on understanding classic just war thought and judging its importance, this Comment flags errors of fact and faulty logic in the Norris essay.

The printed proceedings of the 1960 meeting of the American Catholic Philosophical Association open with two personal testaments: the Presidential Address of Father R. F. Lechner on the professional task of the philosopher to contemplate truth personally, fully and in communication with his fellows and, in reply to his citation for the Aquinas Medal, the address of Dr. Rudolf Allers upon ‘Co-operation and Communication’ in intellectual culture. Next Professor Wilfrid Sellars presents a critical paper, ‘Being and Being Known’ evaluating the (...) ‘over-simplified’ isomorphism of the Thomistic theory of knowing faculty and object in contrast with the ‘radically mistaken’ theories of Descartes and Anglo-Saxon realism. The three other papers concentrate upon current applications of analytic method to philosophical problems. Fr. Ernan McMullin offers a general evaluation of the methods of reductive and linguistic analysts, comparing their insights with their limitations. Fr. Robert Miller analyses in critical detail the theoretical and practical attitudes of the ‘informalist’ group of linguistic analysis to metaphysics, while Fr. W. Norris Clarke more particularly examines their attitude to natural theology. (shrink)

In _Aims: A Brief Metaphysics for Today_, James W. Felt turns his attention to combining elements of Thomas Aquinas's metaphysics, especially its deep ontology, with Alfred North Whitehead's process philosophy to arrive at a new possibility for metaphysics. In his distinctive style, Felt conciselypulls together the strands of epistemology, ontology, and teleology, synthesizing these elements into his own “process-enriched Thomism.” _Aims_ does not simply discuss the strengths and weaknesses of each philosopher’s position, but blends the two into a cohesive (...) argument based on principles derived from immediate experience. Felt arrives at what he calls a “Whiteheadian-type solution,” appealing to his original concept of the “essential aim” as necessary for understanding our existence in a coherent yet unique world. This concise, finely crafted discussion provides a thoroughly teleological, value-centered approach to metaphysics. _Aims_, an experiment in constructive metaphysics, is a thorough and insightful project in modern philosophy. It will appeal to philosophers and students of philosophy interested in enriching their knowledge of contemporary conceptions of metaphysics. “James Felt's _Aims: A Brief Metaphysics for Today _is an excellent book. It is engagingly written with exemplary clarity, compactness of expression, and admirable thoughtfulness. It is a work in constructive metaphysics that offers a marvelous introduction to the beginner, as well as being engaging to the advanced student. While _Aims_ shows the main influences of Aquinas and Whitehead, with Bergson and Merleau-Ponty also important, more importantly it gives expression to the singular appropriation of some of the basic metaphysical issues by James Felt himself. It develops a view of relational realism, with lucid expositions of themes such as the nature of primary being, the act of existing, freedom, participation and God, and the nature of self-knowledge. It distills the author's long reflection on these issues and communicates his considered insights with measured lucidity.” —_William Desmond, Katholieke Universiteit Leuven, Belgium _ “There is a welcome freshness and easy-access approach in this creative presentation of the central philosophical discipline, metaphysics. It starts firmly anchored in our human experience, then moves easily into deeper waters of a proposed Aquinas-Whitehead synthesis.” —_W. Norris Clarke, S.J., Fordham University_ “With modifications to both Aquinas and Whitehead and their complementary interplay, and in contrast to the priority usually given to effective or originating causality, the author argues for the interactive pre-eminence of teleology and existence in the promotion and enhancement of cosmic and interpersonal value. In so doing he seeks to restore to the transcendental Good its appropriate place and role.” —_Kenneth Schmitz, University of Toronto_. (shrink)

Norris et al.'s claim that feedback is unnecessary is compromised by (1) a questionable application of Occam's razor, given strong evidence for feedback in perception; (2) an idealization of the speech recognition problem that simplifies those aspects of the input that create conditions where feedback is useful; (3) Norris et al.'s use of decision nodes that incorporate feedback to model some important empirical results; and (4) problematic linking hypotheses between crucial simulations and behavioral data.

This journey culminates in a justification of philosophy as a genuine form of knowing and thus a natural prelude to metaphysics. Though Felt (...) manages to avoid technical language, the development of his argument is a genuine exercise in philosophic thinking. The outcome is a contemporary expression of a position similar to that of Thomas Aquinas, significantly enriched by insights from Bergson, Whitehead, and phenomenology. (shrink)

ABSTRACTLove is the basis for a moral psychology of forgiveness. I argue for an account of love based on Roy Bhaskar's conception of its five circles, and of the ethical nature of human beings as concrete universals/singulars. Linking this to work of ‘The Forgiveness Project’, I argue that forgiveness can be understood metaphysically in terms of its relation to love of self, of the other, of the relation of self and other, of self, other and the wider community, and of (...) self and other in their ontological depth as unique individuals. Forgiveness involves both a ‘giving to’ and a ‘giving up’, and this can lead to a profound sense of identity between a victim and a perpetrator. Forgiveness is different for each person; it may draw upon a public/legal setting as a proxy for universal judgement; and it confronts social-structural and political elements which may block its development.

In this detailed study, Christopher Norris defends the kinds of arguments advanced by the early realist, Hilary Putnam. Norris makes a point of placing Putnam's work in a wider philosophical context, and relating it to various current debates in epistemology and philosophy of science. Much like Putnam, Norris is willing to take full account of opposed viewpoints while maintaining a vigorously argued commitment to the values of debate and enquiry.

How (Not) to Be Secular is what Jamie Smith calls "your hitchhiker's guide to the present" -- it is both a reading guide to Charles Taylor's monumental work A Secular Age and philosophical guidance on how we might learn to live in our times. Taylor's landmark book A Secular Age (2007) provides a monumental, incisive analysis of what it means to live in the post-Christian present -- a pluralist world of competing beliefs and growing unbelief. Jamie Smith's book is a (...) compact field guide to Taylor's insightful study of the secular, making that very significant but daunting work accessible to a wide array of readers. Even more, though, Smith's How (Not) to Be Secular is a practical philosophical guidebook, a kind of how-to manual on how to live in our secular age. It ultimately offers us an adventure in self-understanding and maps out a way to get our bearings in today's secular culture, no matter who "we" are -- whether believers or skeptics, devout or doubting, self-assured or puzzled and confused. This is a book for any thinking person to chew on. (shrink)

: In the Aristotelian tradition, politics is a matter of public deliberation over questions of justice and injustice. The Bush administration's response to the terrorist attacks of September 11, 2001, has been uniformly hostile to this notion, and it has instead promoted a jingoistic politics of self‐assertion by an America largely identified with the executive branch of its government. This is doubly disturbing, as the executive branch has sought to free itself from international law, multinational commitments, and domestic judicial regulation, (...) even as it has sought to validate itself by demonizing its enemies. This essay draws out the disturbing echoes here of Carl Schmitt's work of the 1920s, in particular of Schmitt's conception of the sovereign as the ungrounded ground of the law and the political as the site of mortal conflict between friend and enemy. The essay argues that Schmitt's position in the twenties, for all of its evident problems, is superior to that of Bush, Wolfowitz, and Ashcroft in at least two senses: Schmitt condemns the idea of waging war for profit and recognizes that such wars will often be disguised as moral crusades waged against the “inhuman”; and he acknowledges that claiming to fight a war for humanity denies one's enemies their humanity, leaving them open to torture and even extermination.

Taking his cue from Wallace Steven's claim that poetry now replaces religion as “life's redemption” and Heidegger's insistence that “the distinction between ‘theoretical’ and ‘poetical’ cannot be applied to philosophical texts”, Richard Rorty celebrated the poetic potential of philosophy. In this prologue, Christopher Norris pays Rorty the compliment of taking his views on the nature and importance of poetry seriously enough to offer an engaging commentary on Rorty's work in poetic form.

Hubert Dreyfus has argued that cases of absorbed bodily coping show that there is no room for self-awareness in flow experiences of experts. In this paper, I argue against Dreyfus’ maxim of vanishing self-awareness by suggesting that awareness of agency is present in expert bodily action. First, I discuss the phenomenon of absorbed bodily coping by discussing flow experiences involved in expert bodily action: merging into the flow; immersion in the flow; emergence out of flow. I argue against the claim (...) that flow experience does not involve an awareness of agency for each of these features, while conceding that fluent agency does not involve self-awareness in the thetic sense. I challenge the assumption that the awareness of fluent agency must be understood in terms of a thetic awareness of agency. Instead, I develop an Anscombean account of the awareness of fluent agency in terms of the phenomenal character of knowing one’s aims. I respond to the challenge that if an Anscombean account of the awareness of agency is to succeed, then agents must be able to answer Anscombean questions. I consider the objection that awareness of agency is not a form of self-awareness by outlining an account of self-awareness as self-synthesis that is distinct from self-perception and self-ascription, but which makes room for self-awareness in expert bodily action.

Do Quine and Carnap distort the social nature of inquiry by privileging individual epistemic subjects? This objection is at the heart of Donald Davidson’s claim that Quine fails to grasp the significance of the concept of truth. In Carnap’s case, the objection may be detected in Charles Morris’s call to ground scientific philosophy in semiotics, the science of signs, rather than syntax, the formal investigation of languages. Drawing out the challenge from Morris’s proposal requires examining a neglected influence on this (...) neglected philosopher: his advisor George Herbert Mead’s social theory of mind. I argue that Morris and Davidson can both be understood as demanding that scientific philosophers socialize their conception of objectivity. (shrink)

Now in a third edition, Introduction to Philosophy: Classical and Contemporary Readings is a highly acclaimed, topically organized collection that covers five major areas of philosophy--theory of knowledge, philosophy of religion, philosophy of mind, freedom and determinism, and moral philosophy. Editor Louis P. Pojman enhances the text's topical organization by arranging the selections into a pro/con format to help students better understand opposing arguments. He also includes accessible introductions to each chapter, subsection, and individual reading, a unique feature for an (...) anthology of this depth. While the book focuses on a compelling sampling of classical material--including selections from Plato, Aristotle, Descartes, Locke, Berkeley, Hume, and Kant--it also incorporates some of philosophy's best twentieth-century and contemporary work, featuring articles by Bertrand Russell, Richard Taylor, John Searle, Thomas Nagel, and others. This third edition contains an expanded glossary, more extensive section introductions, and twelve new selections: Karl Popper: "Epistemology without a Knowing Subject" Richard Rorty: "Dismantling Truth: Solidarity Versus Objectivity" Daniel Dennett: "Postmodernism and Truth" Bruce Russell: "The Problem of Evil: Too Much Suffering" David Chalmers: "Against Materialism: Can Consciousness Be Reductively Explained?"

In 1979, neuroscientists Libet, Wright, Feinstein and Pearl introduced the “delay-and-antedating” hypothesis/paradox based on the results of an on-going series of experiments dating back to 1964 that measured the neural adequacy [brain wave activity] of “conscious sensory experience”. What is fascinating about the results of this experiment is the implication, especially when considered in the light of Merleau-Ponty’s notions of “intentionality” and the “pre-reflective life of human motility”, that the body, and hence not solely the mind, is a thinking thing. (...) The experiments and conclusions of Libet et al. have attracted considerable academic attention and have been used in the development of psychological theories on automotivism and the adaptive unconscious. Moreover, they have engendered a series of important considerations in respect of the question of free will. This paper outlines the connections between the findings of Libet et al. and Merleau-Ponty’s ontology as presented in the Phenomenology of Perception. It is not our intention to argue that the former amounts to new wine in old bottles, but rather to show counterfactually that Merleau-Ponty’s ontology provides a theoretical framework which explains the experimental data obtained by Libet et al., and provides further speculative confirmation of the work stemming from neuro-physical research and emerging theories on the adaptive unconscious.

Metaphysicians go on busily doing metaphysical thinking all over the world, and apparently with a modicum of self-assurance that they are not talking nonsense or pursuing an illusory will-of-the-wisp. Yet other philosophers of empirical, analytical, phenomenological, or other turns of mind seem to have more and more difficulty in understanding just how metaphysicians give meaning and positive content to the vast abstract concepts by which they seek to describe and explain the entire spectrum of reality extending far beyond present or (...) perhaps even possible human experience. Since there is no way of gaining direct insight into dimensions of reality beyond human experience, and since in order to be applied to the whole range of reality these concepts must abstract from purely human experience, it is hard for them to see—and it is a serious problem in itself—how these all-embracing terms can be anything more than empty, formal, verbal symbols or conceptual constructions, with no positive existential content describing reality itself across its whole spectrum. Even the metaphysician himself, though when left alone he may have a sure sense of how to do metaphysical thinking fruitfully, when questioned to explain and justify what he is doing, and is convinced is worth doing, can feel embarrassed and struck dumb as to how to articulate and justify the principles behind the procedures he is following.

Daniel Dennett once invited us to consider super-Martians who were highly advanced scientifically yet lacked all intentional concepts. They spoke the language of austere physics and were capable of perceiving and describing the world at the micro-level. If such beings could accurately report happenings in their environment, make predictions, and generally live out their lives wholly within the scientific image, what would they be missing, Dennett wondered, by virtue of lacking intentional concepts? Dennett’s answer was that they would miss out (...) on various higher level patterns describable by way of mentalistic and semantic vocabulary. (shrink)
