In 1956 Jacques Lacan proposed as interpretation of Edgar Allan Poe's "Purloined Letter" that at once challenged literary theorists and revealed a radically new conception of psychoanalysis. Lacan's far-reaching claims about language and truth provoked a vigorous critique by Jacques Derrida, whose essay in turn has spawned further responses from Barbara Johnson, Jane Gallop, Irene Harvey, Norman Holland, and others. The Purloined Poe brings Poe's story together with these readings to provide, in the words of the editors, "a structured exercuse (...) in the elaboration of textual interpretation. The Purloined Poe reprints the full text of Poe's story, followed by Lacan's "Seminar on 'The Purloined Letter,'" along with extensive commentary by the editors. Marie Bonaparte's and Shoshana Felman's discussions of traditional and contemporary approaches to "psychoanalysing" texts precede Alan Bass's new translation of Derrida's "Purveyor of Truth." The subsequent essays join the Lacan-Derrida debate and offer alternative readings by literary theorists, philosophers, psychologists, and psychoanalysts. The Purloined Poe convenes much of the most important current scholarship on "The Purloined Letter" and presents a rich sampling of poststructuralist discourse. (shrink)

We develop and apply a multi-dimensional account of explanatory depth towards a comparative analysis of inflationary and bouncing paradigms in primordial cosmology. Our analysis builds on earlier work due to Azhar and Loeb (2021) that establishes initial conditions fine-tuning as a dimension of explanatory depth relevant to debates in contemporary cosmology. We propose dynamical fine-tuning and autonomy as two further dimensions of depth in the context of problems with instability and trans-Planckian modes that afflict bouncing and inflationary approaches respectively. In (...) the context of the latter issue, we argue that the recently formulated trans-Planckian censorship conjecture leads to a trade-off for inflationary models between dynamical fine-tuning and autonomy. We conclude with the suggestion that explanatory preference with regard to the different dimensions of depth is best understood in terms of differing attitudes towards heuristics for future model building.

This essay considers what it means to understand natural language and whether a computer running an artificial-intelligence program designed to understand natural language does in fact do so. It is argued that a certain kind of semantics is needed to understand natural language, that this kind of semantics is mere symbol manipulation (i.e., syntax), and that, hence, it is available to AI systems. Recent arguments by Searle and Dretske to the effect that computers cannot understand natural language are discussed, and (...) a prototype natural-language-understanding system is presented as an illustration.

A critical study of John Searle's Minds, Brains and Science (Cambridge, MA: Harvard University Press, 1984).

A standard line in the contemporary philosophical literature has it that physical theories are equivalent only when they agree on their empirical content, where this empirical content is often understood as being encoded in the equations of motion of those theories. In this article, we question whether it is indeed the case that the empirical content of a theory is exhausted by its equations of motion, showing that (for example) considerations of boundary conditions play a key role in the empirical (...) equivalence (or otherwise) of theories. Having argued for this, we show that philosophical claims made by Weatherall (2016) that electromagnetism in the Faraday tensor formalism is equivalent to electromagnetism in the vector potential formalism, and by Knox (2011) that general relativity is equivalent to teleparallel gravity, can both be called into question. We then show that properly considering the role of boundary conditions in theory structure can potentially restore these claims of equivalence and close with some remarks on the pragmatics of adjudications on theory identity.

Canonically, ‘classic’ tests of general relativity (GR) include perihelion precession, the bending of light around stars, and gravitational redshift; ‘modern’ tests have to do with, _inter alia_, relativistic time delay, equivalence principle tests, gravitational lensing, strong field gravity, and gravitational waves. The orthodoxy is that both classic and modern tests of GR afford experimental confirmation of that theory _in particular_. In this article, we question this orthodoxy, by showing there are classes of both relativistic theories (with spatiotemporal geometrical properties different (...) from those of GR) and non-relativistic theories (in which the lightcones of a relativistic spacetime are ‘widened’) which would also pass such tests. Thus, (a) issues of underdetermination in the context of GR loom much larger than one might have thought, and (b) given this, one has to think more carefully about what exactly such tests in fact _are_ testing.

John Searle once said: "The Chinese room shows what we knew all along: syntax by itself is not sufficient for semantics. (Does anyone actually deny this point, I mean straight out? Is anyone actually willing to say, straight out, that they think that syntax, in the sense of formal symbols, is really the same as semantic content, in the sense of meanings, thought contents, understanding, etc.?)." I say: "Yes". Stuart C. Shapiro has said: "Does that make any sense? Yes: Everything (...) makes sense. The question is: What sense does it make?" This essay explores what sense it makes to say that syntax by itself is sufficient for semantics. (shrink)

This essay continues my investigation of `syntactic semantics': the theory that, pace Searle's Chinese-Room Argument, syntax does suffice for semantics (in particular, for the semantics needed for a computational cognitive theory of natural-language understanding). Here, I argue that syntactic semantics (which is internal and first-person) is what has been called a conceptual-role semantics: The meaning of any expression is the role that it plays in the complete system of expressions. Such a `narrow', conceptual-role semantics is the appropriate sort of semantics (...) to account (from an `internal', or first-person perspective) for how a cognitive agent understands language. Some have argued for the primacy of external, or `wide', semantics, while others have argued for a two-factor analysis. But, although two factors can be specified–-one internal and first-person, the other only specifiable in an external, third-person way–-only the internal, first-person one is needed for understanding how someone understands. A truth-conditional semantics can still be provided, but only from a third-person perspective. (shrink)

I advocate a theory of syntactic semantics as a way of understanding how computers can think (and how the Chinese-Room-Argument objection to the Turing Test can be overcome): (1) Semantics, considered as the study of relations between symbols and meanings, can be turned into syntax – a study of relations among symbols (including meanings) – and hence syntax (i.e., symbol manipulation) can suffice for the semantical enterprise (contra Searle). (2) Semantics, considered as the process of understanding one domain (by modeling (...) it) in terms of another, can be viewed recursively: The base case of semantic understanding –understanding a domain in terms of itself – is syntactic understanding. (3) An internal (or narrow ), first-person point of view makes an external (or wide ), third-person point of view otiose for purposes of understanding cognition. (shrink)

This paper argues that we ought to conceive of the Dark Energy problem—the question of how to account for observational data, naturally interpreted as accelerated expansion of the universe—as a crisis of underdetermined pursuit-worthiness. Not only are the various approaches to the Dark Energy problem evidentially underdetermined; at present, no compelling reasons single out any of them as more likely to be true than the other. More vexingly for working scientists, none of the approaches stands out as uncontroversially preferable over (...) its rivals in terms of its rationally warranted promise, i.e. the reasons to further work on, explore, and develop it. We demonstrate this claim by applying a Peircean economic model of pursuit-worthiness in terms of a cognitive cost/benefit estimate—with the instantiation of theory virtues as key indicators of cognitive gains—to the four main Dark Energy proposals (the cosmological constant approach, modified gravity, quintessence, and inhomogeneous cosmologies). According to our analysis, these approaches do not admit of an unambiguous, or uncontroversial, ranking with respect to which ansatz deserves distinguished attention and research efforts. The overall methodological counsel that our analysis underwrites recommends a pragmatic double research strategy forward: to encourage and foster theory pluralism and the search for tests—with the goal of enhancing the testability of the \(\Lambda \) CDM model and “testing it to destruction".

While differing widely in other respects, both neo-Humean and neo-Kantian approaches to normativity embrace an internalist thesis linking reasons for acting to potential motivation. This thesis pushes in different directions depending on the underlying view of the powers of practical reason, but either way it sets the stage for an attack on realist attempts to ground reasons directly in facts about value. How can reasons that are not somehow grounded in motivational features of the agent nonetheless count as reasons for (...) that particular agent, having genuine normative force for her? Won't any realist, externalist view threaten to alienate the individual from the reasons that obtain for her, particularly if she fails (even after rational deliberation) to care about the values that are supposed to ground them? I argue that such objections can successfully be answered, and that externalist views of reasons need not be plagued with normative alienation. Focusing largely on a recent debate between Williams and McDowell over the nature of normative reasons, I show that a value-based externalist theory, when properly conceived, can account for the normative relevance of reasons to the particular agents for whom they obtain. Moreover, Williams's own sophisticated neo-Humeanism turns out to be vulnerable to parallel charges of normative alienation, which it cannot escape without compromising the very psychologistic orientation that has been its chief attraction. Realist externalism about reasons turns out to be a more viable and attractive alternative to both neo-Humeanism and neo-Kantianism than many currently take it to be. (shrink)

I argue that George Nakhnikian's analysis of the logic of cogito propositions (roughly, Descartes's 'cogito' and 'sum') is incomplete. The incompleteness is rectified by showing that disjunctions of cogito propositions with contingent, non-cogito propositions satisfy conditions of incorrigibility, self-certifyingness, and pragmatic consistency; hence, they belong to the class of propositions with whose help a complete characterization of cogito propositions is made possible.

Hauser argues that his pocket calculator (Cal) has certain arithmetical abilities: it seems Cal calculates. That calculating is thinking seems equally untendentious. Yet these two claims together provide premises for a seemingly valid syllogism whose conclusion - Cal thinks - most would deny. He considers several ways to avoid this conclusion, and finds them mostly wanting. Either we ourselves can't be said to think or calculate if our calculation-like performances are judged by the standards proposed to rule out Cal; or (...) the standards- e.g., autonomy and self-consciousness- make it impossible to verify whether anything or anyone (save oneself) meets them. While appeals to the intentionality of thought or the unity of minds provide more credible lines of resistance, available accounts of intentionality and mental unity are insufficiently clear and warranted to provide very substantial arguments against Cal's title to be called a thinking thing. Indeed, considerations favoring granting that title are more formidable than is generally appreciated. Rapaport's comments suggest that, on a strong view of thinking, mere calculating is not thinking (and pocket calculators don't think), but on a weak, but unexciting, sense of thinking, pocket calculators do think. He closes with some observations on the implications of this conclusion. (shrink)

This article presents findings from a series of research studies designed to identify classroom teaching practices that can enhance moral reasoning of undergraduate students in business foundational courses. The research, conducted over five semesters at a Midwestern university, resulted in the development of teaching methods and materials that can, when properly sequenced and integrated into undergraduate business courses, increase levels of student moral reasoning as measured by the revised version of the Defining Issues Test (DIT-2). Findings in this research demonstrate (...) that faculty members who are not specialists in business ethics can effect positive increases in student moral reasoning in non-ethics business courses. However, significant time and effort must be invested in case-based moral decision making, and grade incentives for students to engage the use of an ethical decision-making framework are required.

Increasingly, medical students are required to face up to ethical issues in their training and practice. At the same time, there is growing interest in philosophy courses in the ethical issues raised by medical practice. This textbook, designed primarily for students of medicine, develops the issues to a philosophical level complex enough to be satisfying to students of philosophy as well as MA students on applied ethics courses. The author advocates an approach to medical ethics which breaks out of the (...) straitjacket of the narrow choice between utilitarian or deontological theory, and contains a valuable discussion of practical wisdom. It maintains a balance between case studies and philosophical arguments - which are developed in a historical context, and will be of interest at all levels of the medical profession. (shrink)

We believe that clinical ethics consultants (CECs) should offer advice, options, and recommendations to attending physicians and their teams. In their article in this issue of The Journal of Clinical Ethics, however, Kornfeld and Prager give CECs a somewhat different role. The CEC they describe may at times be more aptly understood as a medical interventionist who appropriates the roles of the attending physician and the medical team than as a traditional CEC. In these remarks, we distinguish the role of (...) the CEC from that of the physician, in contrast to some of these authors’ recommendations, which confuse the two roles. (shrink)

We argued in our joint article that the facilitated consensus model of clinical ethics consultation is incomplete because it does not address the problem of what we have called “unsettled cases.” Sabrina Derrington and April Dworetz, Mark Aulisio, and Al Jonsen have each usefully challenged our claims and conclusions. In this brief article we respond to some of their arguments.

It is well known that people from other disciplines have made significant contributions to philosophy and have influenced philosophers. It is also true (though perhaps not often realized, since philosophers are not on the receiving end, so to speak) that philosophers have made significant contributions to other disciplines and have influenced researchers in these other disciplines, sometimes more so than they have influenced philosophy itself. But what is perhaps not as well known as it ought to be is that researchers (...) in other disciplines, writing in those other disciplines' journals and conference proceedings, are doing philosophically sophisticated work, work that we in philosophy ignore at our peril. Work in cognitive science and artificial intelligence (AI) often overlaps such paradigmatic philosophical specialties as logic, the philosophy of mind, the philosophy of language, and the philosophy of action. This special issue offers a sampling of research in cognitive science and AI that is philosophically relevant and philosophically sophisticated. (shrink)

The role of time in episodic memory and mental time travel is considered in light of findings on humans' temporal memory and anticipation. Time is not integral or uniform in memory for the past or anticipation of the future. The commonalities of episodic memory and anticipation require further study.

A complex of transformations, carried into effect with varying tempos since the beginning of the era of industrial revolutions, has disrupted a certain number of human societies: societies which the ethnologists often call “modern” in opposing them to those labeled “traditional.”.

According to Scheck, Newfeld, and Dwyer (2000), there have been innumerable individuals wrongly convicted of a crime and sentenced to life imprisonment or to death based upon faulty evidence. The historical development of DNA evidence as a tool in the investigative process during the past 25 years is explained/analyzed, and the role of eyewitness evidence in the wrongful conviction of innocent individuals. This paper culminates in the Anthony Capozzi case study where eyewitness testimony wrongfully imprisoned a man before the advent (...) of DNA technology and which ultimately freed him years after the crime. The methodology used is the examination of journal articles, books, and newspaper articles on the phenomenon of wrongful convictions. (shrink)

A systematic approach to the development of an applied scientific research program to meet a developing country's future technological needs is briefly described. The essential features common to all applied science programs are discussed, and approaches to the special problems of a developing country suggested.

ABSTRACT There is a fierce debate about nonsmokers-only hiring policies, also referred to as no-nicotine hiring policies and “tobacco free” hiring policies. The favorable outcomes of no-nicotine hiring policies include reduced health costs, improved worker productivity, enhanced organizational image, and symbolic messaging. The unfavorable consequences of such policies include violating personal liberty, risking a “slippery slope” to other health-compromising behaviors, exacerbating socio-economic disparities, and discriminating against smokers. No-nicotine hiring policies have not been adequately evaluated and a new approach is warranted. (...) The new conditional employment policy for smokers is described with stipulations for the probationary period. Autonomy and fairness are frequently cited as ethical principles to analyze no-nicotine hiring policies. An analysis of ethical principles is presented for no-nicotine hiring policies and the new conditional employment policy. The ethical principle of fairness is rooted in the effectiveness of any policy. Therefore, an evaluation plan is described for the conditional employment policy to assess effectiveness and efficiency. The proposed policy provides a powerful incentive to overcome smoking addictions, preserve the ethical principles of autonomy and fairness, as well as bridge the divide between personal liberty and personal responsibility.

This reexamination of documents purporting to show that Henry of Ghent served on a commission of 16 theologians that compiled the 219 articles condemned in 1277 produces a different picture. It shows that Henry did not serve on a special commission appointed by bishop Tempier but was present at a meeting of all masters, who condemned the articles. It also shows that Tempier did not bypass masters in the faculty of theology, but had them vote on the articles.

Locus equations fail to provide adequate abstraction to capture the English phoneme /g/. They also cannot characterize final consonants or their relation to pre-vocalic consonants. However, locus equations are approximately abstract enough to define the upper limit on phonological distinctions for place of articulation. Hence, locus equations seem to mediate phonetic and phonological perceptual abilities.

Biologists recognize Pavlovian conditioning as a mechanism by which individuals can adaptively modify their social and nonsocial behavior quickly to relevant features of the natural environment. This commentary supports Domjan et al.'s point that psychologists could gain important insights by broadening the range of species and behaviors they study and by continuing to adopt a functional perspective to investigate Pavlovian conditioning and other forms of learning.
