Expressivists about normative thought and discourse traditionally deny that there are nondeflationary normative propositions. However, it has recently been suggested that expressivists might avoid a number of problems by providing a theory of normative propositions compatible with expressivism. This paper explores the prospects for developing an expressivist theory of propositions within the framework of cognitive act theories of propositions. First, I argue that the only extant expressivist theory of cognitive propositions—Michael Ridge's ‘ecumenical expressivist’ theory—fails to explain identity conditions for normative (...) propositions. Second, I argue that this failure motivates a general constraint—the ‘unity requirement’—that any expressivist theory of propositions must provide a unified nonrepresentational explanation of that in virtue of which propositional attitudes have the content that they have. Third, I argue that conceptual role accounts of content provide a promising framework in which to develop an expressivist theory of cognitive propositions. (shrink)

“Brain death,” the determination of human death by showing the irreversible loss of all clinical functions of the brain, has become a worldwide practice. A biophilosophical account of brain death requires four sequential tasks: agreeing on the paradigm of death, a set of preconditions that frame the discussion; determining the definition of death by making explicit the consensual concept of death; determining the criterion of death that proves the definition has been fulfilled by being both necessary and sufficient for death; (...) and determining the tests of death for physicians to employ at the patient's bedside to demonstrate that the criterion of death has been fulfilled. The best definition of death is “the cessation of functioning of the organism as a whole.” The whole-brain criterion is the only criterion that is both necessary and sufficient for death. Brain death tests are used only in the unusual case in which a patient's ventilation is being supported. Brain death critics have identified weaknesses in its formulation. But despite its shortcomings, the whole-brain death formulation comprises a concept and public policy that make intuitive and practical sense and that has been well accepted by many societies.

In this interview, James L. McClelland responds to questions regarding connectionist models of cognition, a theory inspired by information processing in the brain. McClelland explains the distinction between symbolic and non-symbolic processing for a better understanding of mental processes. He argues that connectionist models can perform the computations which we know the brain can perform. In addition, he responds to several general questions on the perspectives of computational models of cognition.

The study of human intelligence was once dominated by symbolic approaches, but over the last 30 years an alternative approach has arisen. Symbols and processes that operate on them are often seen today as approximate characterizations of the emergent consequences of sub- or nonsymbolic processes, and a wide range of constructs in cognitive science can be understood as emergents. These include representational constructs (units, structures, rules), architectural constructs (central executive, declarative memory), and developmental processes and outcomes (stages, sensitive periods, neurocognitive (...) modules, developmental disorders). The greatest achievements of human cognition may be largely emergent phenomena. It remains a challenge for the future to learn more about how these greatest achievements arise and to emulate them in artificial systems. (shrink)

The Fairness Doctrine violated a Constitutional provision for a free press and it failed to guarantee public access to publicly owned broadcast airwaves, as was its intent. The regulation was eliminated in 1987, restoring 1 important free press element to America's broadcast newsrooms. However, public access since deregulation has further deteriorated, while other standards of ethical journalism appear to have been abandoned for higher profits. These factors have renewed the call for re-regulation. This article presents an alternative model in the (...) spirit of the Fairness Doctrine, ethical broadcast journalism, capitalism, and the preservation of the First Amendment. (shrink)

Scepticism about ought simpliciter is the view that there is no such thing as what one ought simpliciter to do. Instead, practical deliberation is governed by a plurality of normative standpoints, each authoritative from their own perspective but none authoritative simpliciter. This paper aims to resist such scepticism. After setting out the challenge in general terms, I argue that scepticism can be resisted by rejecting a key assumption in the sceptic’s argument. This is the assumption that standpoint-relative ought judgments bring (...) with them a commitment to act in accordance with those judgments. Instead, I propose an alternative account of our normative concepts according to which only ought simpliciter judgments commit one to acting in accordance with those judgments. In addition to answering the sceptical challenge, the proposal offers an independently motivated account of what makes a concept normatively authoritative. (shrink)

I consider the role of cognitive modeling in cognitive science. Modeling, and the computers that enable it, are central to the field, but the role of modeling is often misunderstood. Models are not intended to capture fully the processes they attempt to elucidate. Rather, they are explorations of ideas about the nature of cognitive processes. In these explorations, simplification is essential—through simplification, the implications of the central ideas become more transparent. This is not to say that simplification has no downsides; (...) it does, and these are discussed. I then consider several contemporary frameworks for cognitive modeling, stressing the idea that each framework is useful in its own particular ways. Increases in computer power (by a factor of about 4 million) since 1958 have enabled new modeling paradigms to emerge, but these also depend on new ways of thinking. Will new paradigms emerge again with the next 1,000‐fold increase? (shrink)

This paper contends that, even though Husserl demonstrated that consciousness intends objects in the world rather than mental representations, he ultimately failed to provide a convincing account of how the ego constitutes itself and other egos. By reconfiguring consciousness as an operation rather than as a container, Husserl opened consciousness to the world and thereby overcame previous solipsistic frameworks. But despite his attention to the “things themselves,” his fidelity to another maxim—that all sense-bestowing activity be traced back to the operations (...) of the ego—prohibited him from fulfilling his goal of describing otherness accurately. This paper examines the tension between Husserl’s desire to describe phenomena and his mandate to constitute phenomena, to show that both cannot be accomplished simultaneously. If phenomenology is to come to terms with the challenge of otherness and describe self and other adequately, the demand that self and other be constituted within the ego must be relinquished.

Different developmental anomalies produce contrasting deficits in a single, integrated system. In a network that inflects regular and exception verbs correctly, a disproportionate deficit with exceptions occurs if connections are deleted, whereas a disproportionate deficit with regulars occurs when an auditory deficit impairs perception of the regular inflection. In general, contrasting deficits do not license the inference of underlying modularity.

Psychiatric Medicine has been accused justly of making its diagnoses on the patient's report of symptoms and the physician's subjective observations of the patient. The main problem has been the lack of reliable data compounded by the stigma of a mental diagnosis. More recently, third-party pressures have become an added threat to objectivity. New knowledge of brain function, especially neurotransmitters, and more specific and effective medication have made the need for accurate diagnoses more acute. Psychiatry has responded by frequent and (...) often controversial changes in its diagnostic criteria. Much of the controversy stems from a lack of accurate measurements to validate the diagnoses, thereby allowing for differences of opinion of a highly subjective nature. The problem is complicated by the chronic, but irrational, belief that there is a separation between mental and somatic illness.

The lesson is familiar. Kripke’s arguments in favor of a posteriori necessary truths annul the idea that conceivability is a guide to metaphysical possibility because determining that which is a priori is a separate issue from determining that which is necessary. Modal rationalists do not completely agree with this conclusion. Following recent work on two-dimensional semantics, David Chalmers suggests that two distinct semantic values can be assigned to a statement, depending on whether we consider possible worlds as counterfactual or counteractual. (...) The idea is that counterfactual possibilities yield familiar Kripkean intuitions, but that counteractuals fulfill the desired link between a priori conceivability and metaphysical possibility. In this paper, I discuss a problem for modalrationalism that arises through the use of material conditionals, or conditionals in the indicative mood. I then turn to Chalmers’ response, and suggest reasons why it is inadequate. I turn to another response from Chalmers, and suggest that, whilst it solves the fi rst issue, it is incapable of grounding modal rationalism. In conclusion I will suggest a way in which a tempered version of modal rationalism can be salvaged. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 35.2 (2002) 138-152 [Access article in PDF] Respecting the Rupture: Not Solving the Problem of Unity in Plato's Phaedrus James L. Kastely Plato's Phaedrus is a particularly instructive example of the double nature and status of rhetoric, for it embodies a tension at the heart of rhetoric. The first half of the dialogue presents three examples of rhetorical practice, while the second develops a theoretical (...) justification of rhetoric as an art. Thus, the dialogue would seem to offer a productive negotiation of the practice/theory tension. What makes the dialogue interesting, however, is the fact that this negotiation does not occur. The dialogue does not bring theory and practice into a harmonious relation, for there is a troubling discontinuity between its two halves, and rhetorical practice feels fractured. The exploration of eros that had occupied the first half of the dialogue is abandoned before the beginning of the second half, and then, following a logic that is at best associational, Socrates and Phaedrus explore the standards that should govern the practice of rhetoric. The infelicity of this transition raises a question: why did Plato structure the Phaedrus in such a way that it emphasized the dissonance between the two halves of the dialogue? To pose the question this way, however, is to go in a direction different from many of the best contemporary interpretations of the dialogue, which either argue that the dialogue is unified (Griswold 164) or suggest that the dissonance between its two halves reflects a shift in Plato's approach to philosophy (Kahn 373; Nehamas 352). In contrast, I will argue that the rupture in the dialogue is thematically purposive, for it points to an inescapable schism within rhetoric that makes rhetoric philosophically interesting.Socrates' second speech, his palinode to Eros, is a rhetorical tour de force that closes the first half of the dialogue. The importance of the palinode, however, is not limited to its role as an exemplary rhetorical performance, [End Page 138] for it also plays a crucial role in resolving the problem of erotic madness that organizes the intellectual drama of the first half. It would seem reasonable to expect that such an important and powerful moment in the dialogue would, at the very least, play a significant role in the philosophical discussion that composes the dialogue's second half. But that doesn't happen. While Socrates does refer to the palinode in his theoretical discussion of rhetoric, he makes little use of it, and, more important, he is silent on the subject of eros. Both the dramatic organization of the second half of the dialogue and its theoretical discussion cooperate to turn the rhetorical triumph of the palinode into a problem. Why has eros been abandoned as a philosophic topic, and what does this abandoning imply about the erotically grounded rhetoric that Socrates practiced and defended?To make matters worse, Socrates himself dismisses the palinode as a serious effort. He characterizes the speech as little more than a pleasant game, one that is not without value only because "these two certain forms (of gathering and dividing) were stated by chance" (265c). Far from viewing the palinode as possessing philosophical significance, Socrates appears to value it principally for its being a so-so example of a work of rhetoric that has been shaped by dialectic. While it is hard not to take Socrates' dismissal of the seriousness of the speech as partially disingenuous (just prior to his dismissal, he refers to the palinode as serious and reverent [265b]), he also does seem to mean what he says. Whether he is being straightforward or ironic does not finally matter because in either case the problem that occupies him and Phaedrus in the first half has disappeared from the dialogue. And that creates a problem: for if the philosophic issues of the first half of the dialogue drop out, then the dialogue is not coherent.This incoherence is especially troubling given Socrates' explicit endorsement of coherence as an important rhetorical value. In fact, when he begins his... (shrink)

The overall purpose of this paper is to clarify the physical meaning and epistemological status of the term 'measurement' as used in quantum theory. After a review of the essential logical structure of quantum physics, Part I presents interpretive discussions contrasting the quantal concepts observable and ensemble with their classical ancestors along the lines of Margenau's latency theory. Against this background various popular ideas concerning the nature of quantum measurement are critically surveyed. The analysis reveals that, in addition to internal (...) mathematical difficulties, all the so-called quantum theories of measurement are grounded in unjustifiable, classical presuppositions.

Organ donation after the circulatory determination of death requires the permanent cessation of circulation while organ donation after the brain determination of death requires the irreversible cessation of brain functions. The unified brain-based determination of death connects the brain and circulatory death criteria for circulatory death determination in organ donation as follows: permanent cessation of systemic circulation causes permanent cessation of brain circulation which causes permanent cessation of brain perfusion which causes permanent cessation of brain function. The relevant circulation that (...) must cease in circulatory death determination is that to the brain. Eliminating brain circulation from the donor ECMO organ perfusion circuit in thoracoabdominal NRP protocols satisfies the unified brain-based determination of death but only if the complete cessation of brain circulation can be proved. Despite its medical and physiologic rationale, the unified brain-based determination of death remains inconsistent with the Uniform Determination of Death Act. (shrink)
