It should be clear that Lyell's scientific contemporaries would hardly have agreed with Robert Munro's remark that Antiquity of Man created a full-fledged discipline. Only later historians have judged the work a synthesis; those closer to the discoveries and events saw it as a compilation — perhaps a “capital compilation,”95 but a compilation none the less. Its heterogeneity made it difficult to judge as a unity, and most reviewers, like Forbes, concentrated on the first part of Lyell's trilogy. The (...) chapters on glaciation were admired by Lyell's friends but had relatively little appeal to more general readers. His discussion of the species question hedged far too much to please those who accepted the cogency of Darwin's evidence and arguments. This last section of the book blatantly lacks originality or commitment and certainly has no claim to classical status in anthropology.We are left, then, with the first twelve chapters, for it was this portion that dictated the book's title and that amassed the available evidence favoring the antiquity of the human species. Did it do anything more than marshall the evidence that others had discovered? I think not. Lyell could write with style and verve. Principles of Geology is a remarkably readable book. But Antiquity is the work of a geologist, not of a systematic student of man. Despite its occasional touches of power, it never captures the freshness and immediacy of Lubbock's Pre-historic Times nor the theoretical brilliance of E. B. Tylor's Researches into the Early History of Mankind (1865).96 Antiquity utilizes little of the comparative method whereby Lyell's contemporaries used data from modern “savagery” to elaborate the possible social functions of the prehistoric remains being uncovered. It contains little social theory and has virtually no integrated framework. Even the first twelve chapters do not really hang together. As Hooker, commenting to Darwin on Lubbock's review, sadly wrote: “Lubbock in [the] N[atural] H[istory] Review, had in a note called attention to Lyell's ... ‘doing injustice’ to Prestwich & Falconer. I modified this expression ‘injustice’ in Lubbock's paper (which was friendly and apologetic). I am deeply sorry for it, but what can one do? I do think Lyell's first XII chapters a complete mess.”97 In another letter to Darwin, Hooker described this first portion of Antiquity as “confused and confusing.”98Part of the problem, of course, lay in the subject's novelty for Lyell and for most of his contemporaries. At a deeper level, however, I believe that the book accurately reflects Lyell's uncertainties about Darwin's work and its implications for man.99 Leonard Wilson's edition of Lyell's Scientific Journals provides a unique insight into Lyell's mind during the years just before he began to write Antiquity.100 Preoccupied with the human implications of evolutionary biology, Lyell was not clear how many of those implications were compatible with his deep convictions about the dignity of man's place in the cosmos. With a certain naiveté, Lyell complained in 1873 that many of his readers had failed to see the “natural connections” among the three portions of Antiquity.101 Connections could indeed be drawn between man's antiquity and his evolutionary origins; Lyell's private Scientific Journals movingly demonstrate that he was well aware of this fact. But he never fully made the connections in his published writings. Antiquity of Man is more appropriately seen as the last gasp of the heroic period in British geology than as the opening salvo in a new, post-Darwinian anthropological synthesis. Between the founding of the Geological Society of London in 1807 and the middle of the nineteenth century, geology was recognized as one of the most exciting and innovative scientific fields in Britain.102 Lyell himself had contributed much to that drama, and by the 1860's he was a public figure of venerable proportions. More then any other man he represented a geology that had extended the boundaries of process, time, and life. The fundamental achievements of Lyell and his colleagues had been assimilated into the wider Victorian consciousness, yet the earlier public debates about “genesis and geology” had left untouched in its essentials the concept of Man as a moral, responsible, created being.103Lyell never abandoned this view of his own species, and in 1863 it was a completely responsible creature which, under the weight of empirical evidence, Lyell admitted had lived on earth far longer than had previously been thought. Certainly this more generous allowance for human existence was constitutive to what Burrow calls the evolutionary social theory of midcentury Britain.104 Unlike Lyell, the younger representatives of this anthropology quietly accepted both man's antiquity and his aboriginal animality. Herbert Spencer's Principles of Psychology (1855), as well as the other volumes of his grand Synthetic Philosophy, presented as part of the cosmic process the development of human from prehuman beings.105 Tylor's discussion of what in his Researches (1865) he called the “gesture-language” presupposed the gradual and de novo origin of language in early human populations.106 Lubbock's young and polished mind was untroubled by the human implications of Darwin's work, and he cast his Prehistoric Times into such a perfect mold that it and its companionpiece (On the Origin of Civilization, 1870) went through seven editions each between 1865 and World War I, with their original theoretical structures intact. In a way that Lyell could not grasp, Lubbock was intrigued by questions concerning the origins of moral and religious beliefs and did not flinch at the thought of an amoral, atheistic creature as an ancestor.107 Indeed, as the German naturalist Carl Vogt pointed out in his Lectures on Man, translated into English the year after Antiquity, both Darwin's theories and the primitive flint knives of the Stone Age bore witness to a time beyond that imaginable from the condition of the lowest present-day “savage”:From such a low condition [little better than anthropomorphous apes], compared to which that of the so-called savages of the old and new world is a refined civilisation, has the human species gradually extricated itself, in a bitter struggle for existence, which it was well able to maintain, by being gifted with a larger amount of brain and intelligence than that possessed by the surrounding animal world.108The easy integration of biological and social themes was perhaps the distinguishing hallmark of Victorian anthropology of the 1850's and 1860's. After his fashion, Lyell got both themes into Antiquity, but he carefully separated them with a seven-chapter wall of glacial ice. Lyell's anthropology was not that of a thoroughgoing evolutionist like Lubbock, Tylor, or Spencer. For Lyell prehistoric man was not a product of biological evolution. Rude and superstitious he may have been, but he possessed ritual and a belief in a future state, and thus deserved “the epithet of ‘noble,’ which Dryden gave to what he seems to have pictured to himself as the primitive condition of our race: as Nature first made man/when wild in woods the noble savage ran.”109As a systematic argument, Lyell's book was at best a significant failure. As a popularization, it was a success — largely because of the personal stature of its author and the particular moment of its appearance. It helped establish the fact of man's antiquity with a wider Victorian audience, in itself no mean achievement. But Lyell was unable to exploit the fuller implications of his material in the service of a secular science of man. Ironically, he exploited only his colleagues' discoveries. Though the aging Lyell, with failing eyesight but unfailing mental powers, can still be seen as a man of considerable importance, his Antiquity belongs to the carefully circumscribed world of British geology rather than to the less disciplined world of Victorian anthropology.

(1997). Considering moral sensitivity in media ethics courses and research: An essay review by Robert F. Potter. Journal of Mass Media Ethics: Vol. 12, No. 1, pp. 51-57. doi: 10.1207/s15327728jmme1201_4.

This book argues that a conscientiously objecting medical professional should receive an exemption only if the grounds of an objector's refusal are reasonable. It defends a detailed, contextual account of public reasonability suited for healthcare, which builds from the overarching concept of Rawlsian public reason. The author analyzes the main competing positions and maintains that these other views fail precisely due to their systematic inattention to the grounding reasons behind a conscientious objection; he argues that any such view is plausible (...) to the extent that it mimics the 'reason-giving requirement' for conscience objections defended in this work. Only reasonable objections can defeat the prior professional obligation to assign primacy to patient well-being, therefore one who refuses a patient's request for a legally available, medically indicated, and safe service must be able to explain the grounds of their objection in terms understandable to other citizens within the public institutional structure of medicine. The book further offers a novel policy proposal to deploy the Reasonability View: establishing conscientious objector status in medicine. It concludes that the Reasonability View is a viable and attractive position in this debate. A New Theory of Conscientious Objection in Medicine: Justification and Reasonability will be of interest to researchers and advanced students working in bioethics, medical ethics, and philosophy of medicine, as well as thinkers interested in the intersections between law, medical humanities, and philosophy.

In Human Happiness and Morality, noted philosopher Robert Almeder provides lucid introductory explanations of the major ethical theories and traditions, as well as a clear and comprehensive discussion of the proposed answers to three basic questions in ethics: What makes a right act right? Why should I be moral? What is human happiness and how can I attain it? He then ventures beyond the basic questions, describing the relationship between morality and happiness; clearly defining human happiness; and raising the (...) question of whether happiness, so defined, is the likely product of a life lived morally. In the final chapter, Almeder details simple Stoic rules for happy living and shows how it is possible to live the good life despite the existence of unhappiness and failure in others. (shrink)

In this paper I defend the Reasonability View: the position that medical professionals seeking a conscientious exemption must state reasons in support of their objection and allow those reasons to be subject to evaluation. Recently, this view has been criticized by Jason Marsh as proposing a standard that is either too difficult to meet or too easy to satisfy. First, I defend the Reasonability View from this proposed dilemma. Then, I develop this view by presenting and explaining some of the (...) central criteria it uses to assess whether a conscientious objection is proper grounds for extending an exemption to a medical practitioner.

The situationist challenge to global character traits claims that on the basis of findings in social psychology, we should only accept at most the existence of local or context-sensitive traits. In this article I explore a neglected area of J. S. Mill's work to outline an account of context-sensitive traits. This account of traits, coupled with a sophisticated consequentialist ethical framework, suggests an interesting view on which persons govern the circumstances of their actions in order to best promote overall well-being.

This is a book about the role that psychological impairment should play in a theory of criminal liability. Criminal guilt in the Anglo-American legal tradition requires both that the defendant committed some proscribed act and did so with intent, knowledge, or recklessness. The second requirement corresponds to the intuitive idea that people should not be punished for something they did not do 'on purpose' or if they 'did not realize what they were doing'. Unlike many works in this area, this (...) book addresses the automatism and insanity defences by examining the types of functional impairment that typical candidates for these defences actually suffer. What emerges is a much wider conceptual framework that allows us to understand the significance of psychological states and processes for the attribution of criminal responsibility in a manner that is logically coherent, morally defensible, and consistent with research in psychopathology.

Defenders of medical professionals’ rights to conscientious objection (CO) regarding emergency contraception (EC) draw an analogy to CO in the military. Such professionals object to EC since it has the possibility of harming zygotic life, yet if we accept this analogy and utilize jurisprudence to frame the associated public policy, those who refuse to dispense EC would not have their objection honored. Legal precedent holds that one must consistently object to all forms of the relevant activity. In the case at (...) hand, then, I argue that these professionals must also oppose morally innocuous practices that may prevent pregnancy after fertilization. These results reveal that such objectors cannot offer a plausible and consistent objection to harming zygotic life. Additionally, there are good reasons to reject the analogy itself. In either case, these findings call into question the case supporting refusals of EC based on scruples. (shrink)

Blind Realism originated in the deeply felt conviction that the widespread acceptance of Gettier-type counterexamples to the classical definition of knowledge rests in a demonstrably erroneous understanding of the nature of human knowledge. In seeking to defend that conviction, Robert F. Almeder offers a fairly detailed and systematic picture of the nature and limits of human factual knowledge.

Robert Dobbin presents a new translation into clear modern English of the first book of Epictetus' Discourses, accompanied by the first ever commentary on the work in English. The Discourses, composed around AD 100, are a key source for ancient Stoicism, one of the most influential schools of thought in Western philosophy.

Recent survey data gathered from British medical students reveal widespread acceptance of conscientious objection in medicine, despite the existence of strict policies in the UK that discourage conscientious refusals by students to aspects of their medical training. This disconnect demonstrates a pressing need to thoughtfully examine policies that allow conscience objections by medical students; as it so happens, the USA is one country that has examples of such policies. After presenting some background on promulgated US conscience protections and reflecting on (...) their significance for conscience objections by medical students, this paper observes that the dominant approach (following the American Medical Association's conscience clause) is to allow exempted students to instead be evaluated on the basis of alternative curricular activities to learn the associated underlying content. This paper then introduces and discusses an example in which male Muslim students who believe it is wrong to touch members of the opposite sex object to performing physical examinations on female subjects in their medical training. This sort of case, it is argued, causes difficulty for a conscience clause that resolves the dilemma by granting reasonable exemptions in the form of participation in alternative curricular activities: there are cases where one must perform the ‘objectionable’ activity itself in order to learn the necessary content and underlying principles.

This book offers an in-depth analysis of the wide range of issues surrounding "passive euthanasia" and "allow-to-die" decisions. The author develops a comprehensive conceptual model that is highly useful for assessing and dealing with real-life situations. He presents an informative historical overview, an evaluation of the clinical settings in which treatment abatement takes place, and an insightful discussion of relevant legal aspects. The result is a clearly articulated ethical analysis that is medically realistic, philosophically sound, and legally viable.

ELSEWHERE WE HAVE ARGUED that Peirce's later thought manifests a commitment to the thesis that there is a world of physical objects whose existence and properties are neither logically nor causally dependent upon the noetic act of any number of finite minds. 1 In other words, we have argued that Peirce's later thought satisfies the definition of metaphysical realism as classically defined. 2 There are, however, a number of texts which might be cited to support the claim that, for Peirce, (...) the existence and properties of physical objects are causally, and therefore logically, dependent upon the noetic act of the sum of finite minds identified as the community of scientific inquirers. If this latter claim can be substantiated it would seem to follow that either (a) Peirce was fundamentally inconsistent in simultaneously espousing two mutually exclusive doctrines or (b) in his later writings Peirce was not a metaphysical realist at all and that the doctrine on externality can be subsumed into a metaphysical idealism in which the notion of 'external object' does not imply causal or logical independence of the noetic act but rather the experience of duality or otherness. In other words, if the claim that the later Peirce was a metaphysical idealist can be supported, then Peirce was either hopelessly inconsistent or merely trying to account for realistic distinctions within an idealistic framework such as to...

This article argues that practitioners have a professional ethical obligation to dispense emergency contraception, even given conscientious objection to this treatment. This recent controversy affects all medical professionals, including physicians as well as pharmacists. This article begins by analyzing the option of referring the patient to another willing provider. Objecting professionals may conscientiously refuse because they consider emergency contraception to be equivalent to abortion or because they believe contraception itself is immoral. This article critically evaluates these reasons and concludes that (...) they do not successfully support conscientious objection in this context. Contrary to the views of other thinkers, it is not possible to easily strike a respectful balance between the interests of objecting providers and patients in this case. As medical professionals, providers have an ethical duty to inform women of this option and provide emergency contraception when this treatment is requested. (shrink)

Ancell and Sinnott-Armstrong argue that medical providers possess wide freedoms to determine the scope of their practice, and therefore, prohibiting almost any conscientious objections is a bad idea. They maintain that we could create an acceptable system on the whole which even grants accommodations to discriminatory refusals by healthcare professionals. Their argument is premised upon applying a free market mechanism to conscientious objections in medicine, yet I argue their Market View possesses a number of absurd and troubling implications. Furthermore, I (...) demonstrate that the fundamental logic of their main argument is flawed. Thinkers who wish to address the issues raised in this debate in general or by discriminatory conscience objections in particular should avoid the Market View and instead envisage theories that assess the reasons underlying conscientious refusals in medicine.

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 113 phers); nevertheless, I feel that the book would have been more effective pedagogically had they devoted more attention to them than they have. As a specific recommendation, I would suggest several short introductions at strategic places in the text devoted to a brief resum~ of the historical setting in which the philosophers to be discussed found themselves. Once again I should emphasize that, despite the criticisms (...) I have made, I think the book to be an excellent piece of work, which should prove quite successful as an undergraduate text in the history of philosophy. OLIVER JOHNSON University of California, Riverside Plato's Theory of Knowledge. By Norman Gulley. (London: Methuen & Co. Ltd.; New York: Barnes & Noble Inc. Pp. viii ~ 203.) Mr. Gulley gives an account of the development of Plato's theory of knowledge. The impetus to this development he finds in an inconsistency that underlies the attempt to combine an a priori method of analysis with a theory of knowledge based on the doctrines of recollection and the archetype-copy relation of Forms and sensibles. Only in the last chapter, "Mathematical Knowledge," does he suggest a theory of the relation of a priori to empirical knowledge which he thinks might have satisfied Plato. The major part of the work, the first three chapters, concerns the conflicts and readjustments occasioned by the underlying inconsistency. I shall discuss these chapters in terms of a few central points. In chapter I, GuUey attempts to get at the basis of the theoretical difficulties. He points out that Plato first considers philosophic method as independent of the theory of Forms and the theory of recollection (pp. 40 f). In the Meno it is a method of analysis, which is a forerunner of the Phaedo's method of hypothesis, of which the dialectical method is a further development. It is an a priori method. But the theories, which are first hypotheses examined by the method (Phaedo), become later "presuppositions for the effective practice of the method," as, for example, in the Republic. In "recollection" there is an intimate connection between Forms and sensiblcs, but in knowledge there is complete separation. This is what Gulley considers to be the source of the major difficulties. Since I do not find these difficulties, I shall concentrate on their exposition. Gulley notes in the Phaedo two meanings of "giving an account": (1) in terms of a method of propositional analysis; (2) in terms of participation of sensibles in Forms. His explanation of the first offers no difficulties, but of the second there are serious problems. His explication of the second is as follows: To "give an account" is "to explain one's possession of a Form by showing that it is necessarily implied by that judgment of the 'deficiency' of sensible characters which arises as soon as they are recognized" (p. 40). His argument for this interpretation is as follows: "... if to know a Form brings with it the ability 'to give an account', and if to know a Form is to be reminded of it by the sensibles which resemble it (74 b-c), the 'giving of an account' must be explicable within the conception of 'knowledge' implied in the use of the term in 74 b-c" (p. 46). He assumes that Plato is at least consistent. Now in 74 b-c Simmias agrees with Socrates that we have knowledge of equality "in and by itself" and that such things as equal logs and stones "lead us to conceive" of it. Only "recollection," not the preexistent knowledge of Forms is in question here. Since it is assumed that knowledge implies the ability to give an account of what is known, then this instance of knowledge, which occurs in conjunction with perception, implies a similar ability. But one cannot infer from this that the discussion of equality as Plato has discussed it, which is a discussion of it as an example of recollection, is the same thing as the giving an account of equality itself, much less that it is "the only type of account possible" within the theory of Forms. That it is the only possible type is in fact contradicted by the assumption of pre... (shrink)

Elizabeth Anderson claims that states of affairs are merely extrinsically valuable, since we value them only in virtue of the intrinsically valuable persons in those states of affairs. Since it considers states of affairs to be the sole bearers of intrinsic value, Anderson argues that consequentialism is incoherent because it attempts to globally maximize extrinsic value. I respond to this objection by distinguishing between two forms of consequentialist teleology and arguing that Anderson''s claim is either harmless or her argument for (...) the claim is uncompelling. On the first conception of teleology, consequentialists need not hold that states of affairs are the sole bearers of intrinsic value, which allows them to deflect this criticism. On the second account of teleology, even assuming that states of affairs are the sole bearers of intrinsic value, Anderson''s argument does not necessarily defeat such views. (shrink)

This landmark volume brings together the work of the world's leading researchers in sublimated perception. This compilation marks a fundamental shift in the current study of subliminal effects: No longer in question is the notion that perception without awareness occurs. Now, the emphasis is on elucidating the parameters of subliminal effects and understanding the conditions under which stimuli perceived without awareness significantly influence affect, cognition, and behavior. PERCEPTION WITHOUT AWARENESS firmly establishes subliminal perception within the mainstream of psychological science. Well (...) represented here are the two main research branches that have emerged: One directly investigates the nature of subliminal effects; the other uses subliminal techniques as tools for investigating psychological phenomena such as hypnosis, dreaming, repression, social judgment and inference, psychopathology, and symptom formation. Broadly grouped into three main sections, the contributed chapters explore * The cognitive perspective--including implicit memory and implicit perception, the measurement of unconscious perceptual processes, and methods for revealing unconscious processes * The clinical perspective--exploring the cognitive and dynamic aspects of subliminal perception, memory, and consciousness; direct recovery of subliminal stimuli; and validation of subliminal psychodynamic activation * The social perspective--discussing subliminal mere-exposure effects, affect and social perception, and the role of subliminality in social psychology Timely and thought-provoking, PERCEPTION WITHOUT AWARENESS is sure to be of enormous interest to all psychoanalytic clinicians and scholars, as well as cognitive, clinical, and social psychologists whose work touches upon issues relating to psychopathology, perception, cognition, and memory.

Adolescents who are critically, chronically, and terminally ill traditionally have been given little voice in their health care treatment. But over the last three decades attitudes have begun to shift. The legal and medical professions as well as parents and children's advocates have started to recognize that cognitively normal adolescents have decisionmaking capacity and believe these patients ought to have the opportunity to participate in even the toughest of health treatment decisions. Advance directives, if used with sensitivity and care, could (...) prove a valuable means of giving these older pediatric patients a say in their care. (shrink)

Things strike me in a variety ways. F and F# sound slightly different, ripe and unripe tomatoes neither look nor taste nor smell the same, and silk feels smoother than corduroy. In each case, I distinguish an experience of something on the basis of what it is like to be its subject. That is to say, in philosophical parlance, if not quite the vernacular, its “quale,” leads me to categorize it and, thus, respond appropriately to its stimulus. The function of (...) a quale being established, we must define it along with its subject and, as Sartre maintained, their relation. How should we understand the subject and predicate terms and the copula in sentences such as ‘He is listening to Chopin’ or ‘She is seeing the sights of Paris’? Elaborating upon adverbialism, I shall argue that the subject of experiencing is a hylomorphic compound that is temporarily identical to the 'accidental compound' that it forms along with a qualified passion. I begin by explicating the adverbialist’s treatment of qualitative consciousness and defending it against the charge of circularity. (shrink)

Mary Anne Warren provides a well‐known defense of the liberal position in the abortion debate, yet her argument is subject to the objection that it implies that infanticide is morally permissible. In a postscript to her original article, Warren argues that her position does not commit her to the moral acceptability of infanticide. I argue that the reasoning Warren presents in her postscript on infanticide undermines her original main argument in support of the liberal view: she cannot use this argument (...) to both defend the liberal view on abortion and establish that infanticide is morally wrong.

As an introduction to explicating the concept of basic knowledge, I shall examine Aristotle's argument for the existence of basic knowledge and urge two basic points. The first point is that Aristotle's argument, properly viewed, establishes the existence of a kind of knowledge, basic or non-demonstrative knowledge, the definition of which does not require the specification of, and hence the satisfaction of,anyevidence condition. This point has been urged by philosophers like Peirce and Austin but it needs further argumentation because most (...) analytic epistemologists still insist thatallknowledge, whether basic or non-basic, requires the satisfaction of some evidence condition. Secondly, to urge that the basic propositions whose existence is established by Aristotle's argument could be privileged but not known, for the reason that there is no evidence condition for them, would be to adopt a position that either entails wholesale skepticism or undermines the basic distinction between knowledge and belief.

No-arbitrage is the fundamental principle of economic rationality which unifies normative decision theory, game theory, and market theory. In economic environments where money is available as a medium of measurement and exchange, no-arbitrage is synonymous with subjective expected utility maximization in personal decisions, competitive equilibria in capital markets and exchange economies, and correlated equilibria in noncooperative games. The arbitrage principle directly characterizes rationality at the market level; the appearance of deliberate optimization by individual agents is a consequence of their adaptation (...) to the market. Concepts of equilibrium behavior in games and markets can thus be reconciled with the ideas that individual rationality is bounded, that agents use evolutionarily-shaped decision rules rather than numerical optimization algorithms, and that personal probabilities and utilities are inseparable and to some extent indeterminate. Risk-neutral probability distributions, interpretable as products of probabilities and marginal utilities, play a central role as observable quantities in economic systems. (shrink)

De Finetti's treatise on the theory of probability begins with the provocative statement PROBABILITY DOES NOT EXIST, meaning that probability does not exist in an objective sense. Rather, probability exists only subjectively within the minds of individuals. De Finetti defined subjective probabilities in terms of the rates at which individuals are willing to bet money on events, even though, in principle, such betting rates could depend on state-dependent marginal utility for money as well as on beliefs. Most later authors, from (...) Savage onward, have attempted to disentangle beliefs from values by introducing hypothetical bets whose payoffs are abstract consequences that are assumed to have state-independent utility. In this paper, I argue that de Finetti was right all along: PROBABILITY, considered as a numerical measure of pure belief uncontaminated by attitudes toward money, does not exist. Rather, what exist are de Finetti's `previsions', or betting rates for money, otherwise known in the literature as `risk neutral probabilities'. But the fact that previsions are not measures of pure belief turns out not to be problematic for statistical inference, decision analysis, or economic modeling. (shrink)

Much of traditional AI exemplifies the explicit representation paradigm, and during the late 1980''s a heated debate arose between the classical and connectionist camps as to whether beliefs and rules receive an explicit or implicit representation in human cognition. In a recent paper, Kirsh (1990) questions the coherence of the fundamental distinction underlying this debate. He argues that our basic intuitions concerning explicit and implicit representations are not only confused but inconsistent. Ultimately, Kirsh proposes a new formulation of the distinction, (...) based upon the criterion ofconstant time processing.The present paper examines Kirsh''s claims. It is argued that Kirsh fails to demonstrate that our usage of explicit and implicit is seriously confused or inconsistent. Furthermore, it is argued that Kirsh''s new formulation of the explicit-implicit distinction is excessively stringent, in that it banishes virtually all sentences of natural language from the realm of explicit representation. By contrast, the present paper proposes definitions for explicit and implicit which preserve most of our strong intuitions concerning straightforward uses of these terms. It is also argued that the distinction delineated here sustains the meaningfulness of the abovementioned debate between classicists and connectionists. (shrink)
