Cognitive Task Analysis (CTA) helps researchers understand how cognitive skills and strategies make it possible for people to act effectively and get things done. CTA can yield information people needemployers faced with personnel issues, market researchers who want to understand the thought processes of consumers, trainers and others who design instructional systems, health care professionals who want to apply lessons learned from errors and accidents, systems analysts developing user specifications, and many other professionals. CTA can show what makes the workplace (...) workand what keeps it from working as well as it might.Working Minds is a true handbook, offering a set of tools for doing CTA: methods for collecting data about cognitive processes and events, analyzing them, and communicating them effectively. It covers both the "why" and the "how" of CTA methods, providing examples, guidance, and stories from the authors' own experiences as CTA practitioners. Because effective use of CTA depends on some conceptual grounding in cognitive theory and researchon knowing what a cognitive perspective can offerthe book also offers an overview of current research on cognition.The book provides detailed guidance for planning and carrying out CTA, with chapters on capturing knowledge and capturing the way people reason. It discusses studying cognition in real-world settings and the challenges of rapidly changing technology. And it describes key issues in applying CTA findings in a variety of fields. Working Minds makes the methodology of CTA accessible and the skills involved attainable. (shrink)

Adam Smith and Friedrich Hayek saw the liberty principle as focal and accorded it strong presumption, but their wisdom invokes how little we can know. In Knowledge and Coordination, Daniel Klein re-examines the elements of economic liberalism. He interprets Hayek's notion of spontaneous order from the aestheticized perspective of a Smithian spectator, real or imagined. Klein addresses issues economists have had surrounding the notion of coordination by distinguishing the concatenate coordination of Hayek, Ronald Coase, and Michael Polanyi from (...) the mutual coordination of Thomas Schelling and game theory. Clarifying the meaning of cooperation, he resolves debates over whether entrepreneurial innovation enhances or upsets coordination, and thus interprets entrepreneurship in terms of discovery or new knowledge. Beyond information, knowledge entails interpretation and judgment, emergent from tacit reaches of the "society of mind," itself embedded in actual society. Rejecting homo economicus in favor of the "deepself," Klein offers a distinctive formulation of knowledge economics, entailing asymmetric interpretation, judgment, entrepreneurship, error, and correction-and kinds of discovery-which all serve the cause of liberty. This richness of knowledge joins agent and analyst, and meaningful theory depends on tacit affinities between the two. Knowledge and Coordination highlights the recurring connections to underlying purposes and sensibilities, of analysts as well as agents. Behind economic talk of market communication and social error and correction lies Klein's Smithian allegory, with the allegorical spectator representing a conception of the social. Knowledge and Coordination instructs us to declare such allegory. Knowledge and Coordination is an authoritative take on how, by confessing the looseness of its judgments and the by-and-large status of its claims, laissez-faire liberalism makes its economic doctrines more robust and its presumption of liberty more viable.

This paper presents the results of optical interferometry experiments in which the phase of photons in one arm of a Mach-Zehnder interferometer is modified by applying a transverse constriction. An equivalent quantum interferometry experiment using neutron de Broglie waves is discussed in which the observed phase shift is in the spirit of the force-free phase shift of the Aharonov-Bohm effects. In the optical experiments the experimental results are in excellent agreement with predictions.

Early versions of satellite and radiosonde datasets suggested that the tropical surface had warmed more than the troposphere, while climate models consistently showed tropospheric amplification of surface warming in response to human-caused increases in greenhouse gases. We revisit such comparisons here using new observational estimates of surface and tropospheric temperature changes. We find that there is no longer a serious discrepancy between modeled and observed trends in the tropics. Our results contradict a recent claim that all simulated temperature trends in (...) the tropical troposphere are inconsistent with observations. This claim was based on the use of older radiosonde and satellite datasets and on two methodological errors: the neglect of observational trend uncertainties introduced by interannual climate variability and application of an inappropriate statistical “consistency test”.This emerging reconciliation of models and observations has two primary explanations. First, because of changes in the treatment of buoy and satellite information, new surface temperature datasets yield slightly reduced tropical warming relative to earlier versions. Second, recently developed satellite and radiosonde datasets now show larger warming of the tropical lower troposphere. In the case of a new satellite dataset from remote sensing systems, enhancedRSS warming is due to an improved procedure of adjusting for inter-satellite biases. When the RSS-derived tropospheric temperature trend is compared with four different observed estimates of surface temperature change, the surface warming is invariably amplified in the tropical troposphere, consistent with model results. Even if we use data from a second satellite dataset with smaller tropospheric warming than in remote sensing systems RSS, observed tropical lapse rates are not significantly different from those in all model simulations.Our results contradict a recent claim that all simulated temperature trends in the tropical troposphere and in tropical lapse rates are inconsistent with observations. This claim was based on the use of older radiosonde and satellite datasets and on two methodological errors: the neglect of observational trend uncertainties introduced by interannual climate variability and application of an inappropriate statistical “consistency test”.

ABSTRACTAdam Smith infused the expression ‘impartial spectator’ with a plexus of related meanings, one of which is a super-being, which bears parallels to monotheistic ideas of God. As for any genuine, identified, human spectator, he can be deemed impartial only presumptively. Such presumptive impartiality as regards the incident does not of itself carry extensive implications about his intelligence, nor about his being aligned with benevolence towards any larger whole. We may posit, however, a being who is impartial and who holds (...) higher levels of intelligence and of benevolence, and then converse over what her sentiments would be about the matter under discussion. It is natural to conceive of a being who is unsurpassable in such qualities, who is morally supreme, and who naturally takes the definite article the without having been definitized by the writer. Signal passages, new to edition 6, suggest that Smith formulates the man within the breast as a representative of the always present and everywhere morally supreme impartial spectator. When Smith speaks of the man within the breast as ‘the supposed impartial spectator’, we interpret ‘supposed’ as sup-pos-ed, not sup-pos’d. (shrink)

Knowledge consists of the triad: information, interpretation, and judgement. Much of modern political economy has miscarried by proceeding as though knowledge were merely “information” that is, as though interpretation were symmetric and final. Economic prosperity depends greatly on new knowledge or “discovery” of profit opportunities that translate into social betterment. These discoveries are often a transcending of the working interpretation, not merely the acquisition of new information. The evolution of interpretations is key to appreciating voluntarism as a maxim for policy. (...) Smith, Hayek, and Kirzner taught that bad public policy is partly the result of not knowing better, not of evil or greed. Economists may justify their efforts and their salaries chiefly by teaching citizens to know better. Such is the economist’s calling.La connaissance consiste en une triade : information, interprétation, et jugement. Une bonne part de l’économie politique moderne a échoué en assimilant la connaissance à l’information, ce qui revenait à dire que l’interprétation était symétrique et ultime. La prospérité économique repose dans une grande mesure sur l’émergence de nouvelles connaissances ou la “découverte” d’occasions de profit porteuses d’améliorations sociales. Souvent ces découvertes transcendent l’interprétation courante et non seulement l’acquisition de nouvelles informations. L’évolution des interprétations est essentielle pour évaluer le volontarisme en tant que maxime pour la politique. Smith, Hayek et Kirzner nous ont enseigné que des politiques publiques inappropriées résultent en partie d’une déficience de connaissances plutôt que de mauvaises intentions ou d’avidité. Les économistes peuvent justifier leurs efforts et leurs salaires essentiellement en apprenant aux citoyens à s’enrichir de connaissances. Telle est la vocation de l’économiste. (shrink)

This study probes whether a prosopagnosic patient can make accurate explicit affective judgements towards faces. Patient MJH was shown photographs of faces of well-liked family members and public figures rated as “evil” by opinion polls. MJH was asked to rate each face on two 7-point scales (Likeability and Pleasantness). Since he is unable to explicitly recognise faces, his ratings were based on his evaluative reaction to the faces presented. In a second phase of the experiment, MJH was told the name (...) of the faces previously presented and asked to rate them using the same scales. MJH's Likeability ratings during the picture-viewing phase of the experiment and the explicit phase were highly correlated. Based on these findings, we propose that thought consists of an explicit declarative and an implicit emotional aspect, which may become dissociated in prosopagnosia. (shrink)

In her re-analysis of the evidence presented in Klein and Nichols (2012) to support their argument that patient R.B. temporarily lost possessory custody of consciously apprehended objects (in this case, objects that normally would be non-inferentially taken as episodic memory), Professor Roache concludes Klein and Nichols's claims are untenable. I argue that Professor Roache is incorrect in her re-interpretation, and that this is due, in part, to lack of sufficient familiarity with psychological theory on memory as well as (...) clinical literature on felt loss of ownership of one’s intentional objects.

In the last few years, off-line simulation has become an increasingly important alternative to standard explanations in cognitive science. The contemporary debate began with Gordon (1986) and Goldman's (1989) off-line simulation account of our capacity to predict behavior. On their view, in predicting people's behavior we take our own decision making system `off line' and supply it with the `pretend' beliefs and desires of the person whose behavior we are trying to predict; we then let the decision maker reach a (...) decision on the basis of these pretend inputs. Figure 1 offers a `boxological' version of the off-line simulation theory of behavior prediction.(1). (shrink)

This volume offers the first English language collection of academic essays on the post-Holocaust thought of Jean Améry, a Jewish-Austrian-Belgian essayist, journalist and literary author. Comprehensive in scope and multi-disciplinary in orientation, contributors explore central aspects of Améry's philosophical and ethical position, including dignity, responsibility, resentment, and forgiveness.

In their critique of Klein (2014a), Trafimow and Earp present two theses. First, they argue that, contra Klein, a well-specified theory is not a necessary condition for successful replication. Second, they contend that even when there is a well-specified theory, replication depends more on auxiliary assumptions than on theory proper. I take issue with both claims, arguing that (a) their first thesis confuses a material conditional (what I said) with a modal claim (Trafimow and Earp’s misreading of what (...) I said), and (b) their second thesis has the unfortunate consequence of refuting their first thesis. (shrink)

Episodic memory often is conceptualized as a uniquely human system of long-term memory that makes available knowledge accompanied by the temporal and spatial context in which that knowledge was acquired. Retrieval from episodic memory entails a form of first–person subjectivity called autonoetic consciousness that provides a sense that a recollection was something that took place in the experiencer’s personal past. In this paper I expand on this definition of episodic memory. Specifically, I suggest that (a) the core features assumed unique (...) to episodic memory are shared by semantic memory, (b) episodic memory cannot be fully understood unless one appreciates that episodic recollection requires the coordinated function of a number of distinct, yet interacting, “enabling” systems. Although these systems – ownership, self, subjective temporality, and agency – are not traditionally viewed as memorial in nature, each is necessary for episodic recollection and jointly they may be sufficient, and (c) the type of subjective awareness provided by episodic recollection (autonoetic) is relational rather than intrinsic – i.e., it can be lost in certain patient populations, thus rendering episodic memory content indistinguishable from the content of semantic long-term memory.

A 4-space formulation of Dirac's equation gives results formally identical to those of the usual Klein paradox. However, some extra physical detail can be inferred, and this suggests that the most extreme case involves pair production within the potential barrier.

OVERVIEWWe ambitiously reexamine Smith’s moral theory in relation to Hume’s. We regard Smith's developments as glorious and important. We also see them as quite fully agreeable to Hume, as enhancement, not departure. But Smith represents matters otherwise! Why would Smith overstate disagreement with his best friend?One aspect of Smith’s enhancement, an aspect he makes very conspicuous, is that between moral approval and beneficialness there is another phase, namely, the moral judge's sense of propriety. With that phase now finding formulation, Smith, (...) if only implicitly, generates a spiral of beneficialness and propriety, a spiral shown in Figure 7 in the present paper. We consider Figure 7, illustrating the spiral, to be the most important arrival point in the present paper; it highlights the non-foundationalism of Smith's ethics. But to arrive at the spiral, we must engage in extensive exegesis.In Part IV of The Theory of Moral Sentiments, Smith presents a foil against which he develops his own theory, a foil supposedly representing Hume. According to the foil, moral approval derives from ‘utility.’ But, in multiple ways, the foil is misleading. We provide an interpretation of Hume, notably his four-factor account of moral approval, before examining Smith's representation of Hume.One twist is that Smith used the words utility and useful differently than Hume did – Smith quietly stretched them to include species of agreeableness, thereby obscuring the importance of agreeableness in Hume’s theory.Another, more significant problem is that Smith allows the impression that in Hume moral approval derives quite determinately from beneficialness. In fact Hume conveys the interpretive and sentimental spaciousness of the operations that generate moral approval; here, Hume even speaks repeatedly of ‘proper sentiments’, thus almost using the term propriety himself.But the propriety phase in Smith opens up to a key facet of Smith’s development on Hume: He poeticizes a locus of sympathy not emphasized in Hume – namely, that between the moral judge and her own man within the breast; that locus enters the theory in addition to the sympathies emphasized in Hume, not in lieu of them. We distinguish lateral sympathy, which is important in Hume’s thought, and vertical sympathy, which is especially characteristic of Smith’s more inner-directed and allegorical thought. Smith embraces Hume’s lateral sympathy and enhances moral theory by adding formulations that elaborate vertical sympathy.Next, we come to something of a twist in the whole matter: We show that – as Smith well knew all along! – propriety is a species of agreeableness! Smith’s propriety phase represents another dimension within which such agreeableness lives: Smith’s vertical dimension thus gives rise to a spiral representing the diachronic development of the judge herself. It is a spiral of beneficialness and propriety: Each propriety phase in the next loop of the spiral engenders a species of agreeableness now as a part of beneficialness.Smith's developments on Hume, then, involve the following three facets: formulation of the propriety phase; the poetic elaboration of vertical sympathy; the diachronic spiral of propriety and beneficialness.The three facets come together, especially in Ed. 6 of The Theory of Moral Sentiments. The whole development goes beyond Hume, but, really, is agreeable to Hume – though Smith himself portrays his developments as disagreeing with features of Hume's moral theory.We speculate that Smith was more or less aware of all that that we say, including the absense of any really substantive disagreement. Why, in that case, would Smith have proceeded as he did? We address that question at the end of the piece. Our speculations suggest a method in the madness. (shrink)

Benjamin Libet compared the perceived time of direct brain stimulation to the perceived time of skin stimulation. His results are among the most controversial experiments at the interface between psychology and philosophy. The new element that I bring to this discussion is a reanalysis of Libet's raw data. Libet's original data were difficult to interpret because of the manner in which they were presented in tables. Plotting the data as psychometric functions shows that the observers have great uncertainty about the (...) relative timing of events, as seen the shallow psychometric slopes. A second indication of uncertainty comes from Libet's use of three response categories, A first; B first; and A and B simultaneous. The large number of “perceptually simultaneous” responses provides a further measure of the difficulty of the judgment. There are thus a very broad range of stimulus delays in which the subject is unable to make an accurate ordering response. These points provide evidence that there is no compelling reason to invent exotic or ad hoc mechanisms to account for Libet's data since the uncertainty window is large enough to allow simple mechanism such as memory shifts. Libet argued that his data provide evidence for a backward referral in time. I argue that even though Libet's own data are weak, there are good arguments for a backward referral mechanism to help the subject make sense out of the tangled chaos of asynchronous information associated with experienced events.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Pragmatism's Evolution: Organism and Environment in American Philosophy by Trevor PearceAlexander KleinTrevor Pearce. Pragmatism's Evolution: Organism and Environment in American Philosophy. Chicago: The University of Chicago Press, 2020. Pp. 384. Paperback, $35.00.Pragmatist pioneers were young lions in the days of Darwin. Evolutionary-biological thinking infused this philosophical movement from the start. And yet the last time a major monograph appeared on classic pragmatism and evolutionary biology—Philip Wiener's Evolution and (...) the Founders of Pragmatism (New York: Harper Torchbooks, 1949)—the author could personally thank Ralph Barton Perry, William James's junior colleague and eventual biographer. John Dewey himself wrote the foreword.Almost seventy-five years later, we have Trevor Pearce's painstakingly researched Pragmatism's Evolution. The author has graduate training in both biology and philosophy and is a former student of William Wimsatt and Robert Richards's (343). The book offers an intricate portrait of how debates about evolutionary biology informed the thinking of a loose-knit group of pragmatists between the years 1860 and 1910. While a remarkable variety of figures are discussed, ten pragmatists command the most attention: Chauncey Wright, C. S. Peirce, Francis Ellingwood Abbot, John Fiske, William James, Josiah Royce, John Dewey, Jane Addams, G. H. Mead, and W. E. B. Du Bois (18). Call them "the American Ten."Without downplaying Darwin, an overarching theme is the special significance of Herbert Spencer. Despite many specific disagreements with him (see e.g. 74, 207–8, 253–54, 281), the American Ten all accepted something more fundamental from Spencer: an intellectual framework that explains mind and morality in terms of functional relationships between organism and environment.After an introduction outlining what Pearce identifies as four chronological "cohorts" of pragmatists (more on this concept below), he examines the 1860s and 1870s reception of Darwin (chapter 1) and Spencer (chapter 2), showing how senior pragmatists like Wright, Peirce, and James defended evolution during this period. In chapter 2, we meet the Metaphysical Club's arch Spencerian, John Fiske, and we get a reading of James's critique of Spencer's psychology and sociology. Chapter 3 gives a highly detailed, reference-work-like portrait of the second cohort's training in evolutionary biology during the 1880s—chiefly Royce, Dewey, Addams, Mead, and Du Bois. In chapter 4, we learn that in the 1880s and 1890s, idealists like Edward Caird, Samuel Alexander, David George Ritchie, and Josiah Royce all co-opted ideas from evolutionary biology, which they apparently thought compatible with Hegelian dialectics. Chapter 5 shows that central planks of Peirce's metaphysics and Dewey's ethics are responsive to an 1890s dispute over the causes of the biological variation upon which selection acts (the so-called "factors" debate). The final two chapters show how pragmatist ethics (chapter 6) and epistemology (chapter 7) were infused with substantive ideas about evolution and about scientific experiment more generally.The depth and use of historical scholarship on offer here are both remarkable. On depth, Pearce draws from nineteen special collections and archives housed at institutions from California to Manchester, UK. The reference list (published on Pearce's website) runs [End Page 160] to 118 pages and was apparently too long for inclusion in the book. Archival research and lengthy bibliographies are to be expected in today's history of philosophy. But the sheer range of sources Pearce draws from is, by any measure, impressive.The use to which he puts those sources is provocative. Close reading, and in particular argument reconstruction, is usually the stock in trade for historians of philosophy. Pearce takes a different approach (7), seeking interpretive insight through a kind of philosophical network analysis. The nodes are mainly philosophers, scientists, and social critics. Unlike digital network analyses, Pearce connects his nodes by hand, via a great multiplicity of social, educational, and intellectual relations. We learn who studied evolution where, with whom, and when; what specific texts were assigned in classes taken, in classes taught; who attacked whom, who sided with whom; and so on.The resulting networks are rich, though they can be difficult to track due to their complexity. At its best, the book uses networks to produce genuine insights that... (shrink)

The late Jacob Klein’s important book is, remarkably, a lucid presentation of esoteric argument. Dealing with the famed Platonic triad, Theaetetus, Sophist, and Statesman, Klein settles the dispute about the missing dialogue, "The Philosopher," by first denying that it is missing and second showing that it is unnecessary. He argues, in short, that the triad is a dyad. That argument is reinforced by the distinction Klein strongly implies between the Socratic Theaetetus and the Eleatic Sophist and Statesman. (...) "We can now understand why the conversations of the ‘trilogy’ occur in two, not three, days and why the Sophist, the Statesman, and the Philosopher are dealt with in two, not three, dialogues".

Multifunctionality poses significant challenges for human brain mapping. Cathy Price and Karl Friston argue that brain regions perform many functions in one sense and a single function in another. Thus, neuroscientists must revise their “cognitive ontologies” to obtain systematic mappings. Colin Klein draws a different lesson from these findings: neuroscientists should abandon systematic mappings for context-sensitive ones. I claim that neither account succeeds as a general treatment of multifunctionality. I argue that brain areas, like genes or organs, are multifunctional (...) in different ways. I call this the “functional heterogeneity hypothesis.” I contend that different multifunctional parts require different mapping strategies. (shrink)

A simple random walk model has been shown by Gaveauet al. to give rise to the Klein-Gordon equation under analytic continuation. This absolutely most probable path implies that the components of the Dirac wave function have a common phase; the influence of spin on the motion is neglected. There is a nonclassical path of relative maximum likelihood which satisfies the constraint that the probability density coincide with the quantum mechanical definition. In three space dimensions, and in the presence of (...) electromagnetic interaction, the Lagrangian for this optimal, nonclassical path coincides with the Lagrangian of the Dirac particle. The nonrelativistic, or diffusion, limit is shown to be a formal consequence of Einstein's dynamical equilibrium condition; the continuity equation reduces to the same diffusion equation derived from Schrödinger's equation. The relativistic, massless limit, which would describe a neutrino, is comparable (in the sense of analytic continuation) to a nonviscous liquid whose molecules possess internal degrees of freedom.

This paper presents a new Symmetrical Interpretation (SI) of relativistic quantum mechanics which postulates: quantum mechanics is a theory about complete experiments, not particles; a complete experiment is maximally described by a complex transition amplitude density; and this transition amplitude density never collapses. This SI is compared to the Copenhagen Interpretation (CI) for the analysis of Einstein’s bubble experiment. This SI makes several experimentally testable predictions that differ from the CI, solves one part of the measurement problem, resolves some inconsistencies (...) of the CI, and gives intuitive explanations of some previously mysterious quantum effects.

Are spheres multiply realizable? A venerable tradition implies that they are. Putnam’s discussion of the peg and holes (in [Putnam, 1975]) is often taken to show that all volumetric shape properties are multiply realizable . The argument runs: (a) physics is the science of the “ultimate constituents” (Putnam’s phrase) of matter, and so (b) physics can only track the behavior of each of the simple constituents of a particular system, but (c) tediously tracking individual particles doesn’t make for a very (...) good explanation, so (d) there must be an explanation outside of physics that does talk about shape, and that we should prefer because it abstracts away from the micro-level details of particular spheres.

In a 1994 ANALYSIS article Peter Klein and Ted Warfield show that an epistemically more coherent set of beliefs often has a smaller unconditional probability of joint truth than some of its less coherent subsets. They conclude that epistemic justification, as understood in one version of a coherence theory of justification, is not truth conducive. After getting clear about what truth conduciveness requires, I show that their argument does not tell against BonJour's coherence theory.

This volume "contains eight articles dealing with the intellectual and institutional developments in physics from the mid-1840’s to the mid-1920’s. The primary focus is on the quantum and relativity theories and Einstein’s contributions to these theories. The secondary focus is on thermodynamics and its kinetic theory basis in the nineteenth century." Slightly more than one third of the book is devoted to various aspects of Einstein’s work: M. J. Klein analyzes his difference with Bohr in 1923-1925; R. McCormmach traces (...) the problem area which he extracted from Lorentz’ electron theory in about the first decade of this century; and S. Goldberg considers the British response to his special theory of relativity in 1905-1911. In the editor’s foreword, McCormmach illustrates from the current investigation of Einstein a general thesis about "the limitations of contemporary writing in the history of science." Thus, this anthology may well become a standard secondary source for Einstein scholarship. A fourth of the book has to do with thermodynamics: Y. Elkana follows Helmholtz’ formulation of its first law ; E. E. Daub looks at the evolution of concepts essential to its second law ; and E. W. Garber delineates Clausius’ contribution to its underpinnings. Just two articles are unrelated to these two foci: P. Forman, in the longest paper in the volume, considers Lande’s search for a theory of the anomalous Zooman effect in 1919-1921; and R. Sviedrys, in an exchange with A. Thackray, examines the rise of physical science at Cambridge University during the Victorian era. (shrink)

Requiring covariance of Maxwell's equations without a priori imposing charge invariance allows for both spin-1 and spin-1/2 transformations of the complete Maxwell field and current. The spin-1/2 case yields new transformation rules, with new invariants, for all traditional Maxwell field and source quantities. The accompanying spin-1/2 representations of the Lorentz group employ the Minkowski metric, and consequently the primary spin-1/2 Maxwell invariants are also spin-1 invariants; for example, Φ2−A2, E2−B2+2iE⋅B−2. The associated Maxwell Lagrangian density is also the same for both (...) spin-1 and spin-1/2 fields. However, in the spin-1/2 case, standard field and source quantities are complex and both charge and gauge invariance are lost. Requiring the potentials to satisfy the Klein–Gordon equation equates the Maxwell and field-potential equations with two Dirac equations of the Klein–Gordon mass, and thus one complex Klein–Gordon Maxwell field describes either two real vector fields or two Dirac fields, all of the same mass.

How questions are understudied in philosophy and linguistics. They can be answered in very different ways, some of which are poorly understood. Jaworski identifies several types: ‘manner’, ‘method, means or mechanism’, ‘cognitive resolution’, and develops a logic designed to enable us to distinguish among them. Some key questions remain open, however, in particular, whether these distinctions derive from an ambiguity in how, from differences in the logical structure of the question or from contextual underspecification. Arguing from two classes of responses, (...) adverbs and by gerunds, I give the answer that the logical structure of the question is indeed relevant: loosely, manners are adjuncts but methods are arguments.

The merit of Plato’s Laws remains largely untapped by those seeking genuinely collaborative models of the doctor–patient tie as alternatives to paternalism and autonomy. A persistent difficulty confronting proposed alternatives has been surpassing the notion of pronounced intellectual and values asymmetry favoring the doctor. Having discussed two prominent proposals, both of which evince marked paternalism, I argue that reflection on Plato yields four criteria that a genuinely collaborative model must meet and suggest how the Laws addresses them. In the process, (...) the Laws’ doctor–patient tie is shown to be far more nuanced than interpreters have previously observed. Although Plato’s account will not solve our own quandaries, it illustrates how one might retain asymmetry of a kind without capitulating to familiar oppositional modalities. Through this account, I hope to show that the Laws merits fuller inclusion in contemporary discussions than it has heretofore received. (shrink)
