In the TACITUS project for using commonsense knowledge in the understanding of texts about mechanical devices and their failures, we have been developing various commonsense theories that are needed to mediate between the way we talk about the behavior of such devices and causal models of their operation. Of central importance in this effort is the axiomatization of what might be called commonsense metaphysics. This includes a number of areas that figure in virtually every domain of discourse, such as granularity, (...) scales, time, space, material, physical objects, shape, causality, functionality, and force. Our effort has been to construct core theories of each of these areas, and then to define, or at least characterize, a large number of lexical items in terms provided by the core theories. In this paper we discuss our methodological principles and describe the key ideas in the various domains we are investigating. (shrink)

Adam Smith is the best known among economists for his book, The Wealth of Nations, often viewed as the keystone of modern economic thought. For many he has become associated with a quasi-libertarian laissez-faire philosophy. Others, often heterodox economists and social philosophers, on the contrary, focus on Smith's Theory of Moral Sentiments, and explore his moral theory. There has been a long debate about the relationship or lack thereof between these, his two great works. This work treats these dimensions of (...) Smith's work as elements in a seamless moral philosophical vision, demonstrating the integrated nature of these works and Smith's other writings. This book weaves Smith into a constructive critique of modern economic analysis and builds bridges between that discourse and the other social sciences. (shrink)

Traditionally, organ retrieval from cadavers has taken place only in cases where the declaration of death has occurred using “brain death” criteria. Under these criteria, specific tests are performed to demonstrate directly a lack of brain activity. Recently, as a result of efforts to increase organ procurement, attention has been directed at the use of so-called “non-heart-beating” donors : individuals who are declared dead not as a result of direct measurements of brain function, but rather as a result of the (...) cessation of heart and respiratory functions. Attempts to obtain organs from such individuals have recently resulted in substantial negative publicity. Claims were made that the deaths of patients were being accelerated in order to get organs, and that sometimes organs were being removed from patients who were not yet dead. (shrink)

Most people know precious little about the risks and benefits of participating in a clinical trial--a medical research study involving some innovative treatment for a medical problem. Yet millions of people each year participate anyway. Patients at Risk explains the reality: that our current system intentionally hides much of the information people need to make the right choice about whether to participate. Witness the following scenarios: -Hundreds of patients with colon cancer undergo a new form of keyhole surgery at leading (...) cancer centersnever -Tens of thousands of women at high risk of developing breast cancer are asked to participate in a major research study. They are told about the option of having both breasts surgically removed but not told about the option of taking a standard osteoporosis pill that might cut the risk of getting breast cancer by one-half or more. Patients at Risk written by two nationally prominent experts, is the first book to reveal the secrets that many in the research establishment have fought long and hard to keep from patients. It shows why options not commonly knownincluding getting a new treatment outside of a research studycan often be the best choice. It explains how patients can make good decisions even if there is only limited information about a treatments effect. And it does this through the eye-opening stories of what is happening daily to thousands of people. Day after day, we are learning how little we know about what really works. Headlines regularly announce that a previously unquestioned treatmenthormone replacement therapy, drugs such as Vioxx or Celebrexmay now be much riskier than we thought. The latest book in a surge of recent books criticizing the medical establishment (but the first to look at clinical trials specifically), Patients at Risk helps to empower patients to survive in a world of medical uncertainty, and makes positive recommendations for systemic reform.

In the creation myth of the Timaeus Plato describes God as wishing that all things should be good so far as is possible. Wherefore, finding the whole visible sphere of the world not at rest, but moving in an irregular fashion, out of disorder He brought order, thinking that this was in every way an improvement. To achieve His end He placed intelligence in soul and soul in body, reflecting that nothing unintelligent could ever be better than something intelligent . (...) From this account of creation it would seem that God confronted a chaotic world whose disorderly motions existed in full independence of the principle of soul. Yet, in his doctrinal pronouncements in the Laws and the Pbaedrus on the origin of motion, Plato declares soul to be elder born than bodies and the prime source of all their changes and transformations.

This project focuses on the extent to which disability insurers should be allowed to use genetic information in underwriting and rate-setting, but this subject cannot be completely isolated from the related questions of whether life and health insurers should also have this discretion. Federal and state laws place significant restrictions on insurers’ use of genetic information in health insurance, but regulation of such use in life and disability insurance is considerably more modest. This essay examines the reasons for this disparity (...) and discusses the implications for future proposals to regulate disability insurers’ use of genetic information in underwriting and rate-setting. The thesis is relatively simple: Communitarian values are stronger in health insurance than in life and disability insurance. Accordingly, the public is likely to acquiesce to insurers’ insistence that they be allowed to make distinctions among insureds in disability insurance that would not be tolerated in health insurance.

Suppose that someone has a serious illness. The illness will likely lead to significant disabilities, and may even cause death. Existing treatments are unsatisfactory. The patient learns about a clinical trial, in which some allegedly promising new treatment for that illness is being tested.Such seriously ill patients for whom existing treatments are unsatisfactory have sometimes been categorized as medically vulnerable in the literature. Should these patients indeed be considered vulnerable subjects and be provided with special protections? And if the answer (...) is yes, then what are those special protections? This article explores the possible answers to these questions.The federal regulations for the protection of research subjects have several provisions addressing the concept of vulnerability. The three subparts Subparts B, C, and D deal with specific categories of vulnerable subjects, but do relatively little to address broader issues relating to vulnerability that might apply to a category such as the medically vulnerable. The Common Rule is the only section containing general discussions of vulnerability. (shrink)

Only 19 new molecular entities and 3 biologics were approved by the Food and Drug Administration in 2007, the lowest rate in 24 years. This disappointing output occurred despite steady clinical trial and regulatory review times, the FDA maintaining high approval rates, and the pharmaceutical industry consistently reporting increasing revenues. A government report suggests that fewer new drug applications have been submitted to the FDA by the pharmaceutical industry in recent years. These data have rekindled the debate as to the (...) origins of pharmaceutical innovation and the comparative importance of public and private sources in contributing to drug discovery.

When applied in the health sector, AI-based applications raise not only ethical but legal and safety concerns, where algorithms trained on data from majority populations can generate less accurate or reliable results for minorities and other disadvantaged groups.

Artificial intelligence (AI) has attracted an increasing amount of attention, both positive and negative. Its potential applications in healthcare are indeed manifold and revolutionary, and within the realm of medical imaging and radiology (which will be the focus of this paper), significant increases in accuracy and speed, as well as significant savings in cost, stand to be gained through the adoption of this technology. Because of its novelty, a norm of keeping humans “in the loop” wherever AI mechanisms are deployed (...) has become synonymous with good ethical practice in some circles. It has been argued that keeping humans “in the loop” is important for reasons of safety, accountability, and the maintenance of institutional trust. However, as the application of machine learning for the detection of lumbar spinal stenosis (LSS) in this paper’s case study reveals, there are some scenarios where an insistence on keeping humans in the loop (or in other words, the resistance to automation) seems unwarranted and could possibly lead us to miss out on very real and important opportunities in healthcare—particularly in low-resource settings. It is important to acknowledge these opportunity costs of resisting automation in such contexts, where better options may be unavailable. Using an AI model based on convolutional neural networks developed by a team of researchers at NUH/NUS medical school in Singapore for automated detection and classification of the lumbar spinal canal, lateral recess, and neural foraminal narrowing in an MRI scan of the spine to diagnose LSS, we will aim to demonstrate that where certain criteria hold (e.g., the AI is as accurate or better than human experts, risks are low in the event of an error, the gain in wellbeing is significant, and the task being automated is not essentially or importantly human), it is both morally permissible and even desirable to kick the humans out of the loop.

Drug Safety Communications are used by the Food and Drug Administration to inform health care providers, patients, caregivers, and the general public about safety issues related to FDA-approved drugs. To assess patient knowledge of the messaging contained in DSCs related to the sleep aids zolpidem and eszopiclone, we conducted a large, cross-sectional patient survey of 1,982 commercially insured patients selected by stratified random sampling from the Optum Research Database who had filled at least two prescriptions for either zolpidem or eszopiclone (...) between July 1, 2012 and June 30, 2013. Among the 594 respondents, two-thirds reported hearing generally about drug safety information prior to starting a new drug, with the remaining one-third “rarely” or “never” hearing such information. Providers and pharmacists were primary sources of drug safety information. Two-thirds of zolpidem users and half of eszopiclone users reported having heard about the related DSC messages, ability to accurately identify the major factual messages was limited. Respondents reacted to new drug safety information about their sleep aids by reporting that they would want to learn about alternative ways to help them sleep and seek out more information about the safety of their specific sleeping pill. Opportunities may exist for the FDA to work with providers and pharmacies to help ensure the DSC information is more widely received and is more fully understood by those taking the affected medications.

Risk prediction in emergency medicine (EM) holds unique challenges due to issues surrounding urgency, blurry research-practise distinctions, and the high-pressure environment in emergency departments (ED). Artificial intelligence (AI) risk prediction tools have been developed with the aim of streamlining triaging processes and mitigating perennial issues affecting EDs globally, such as overcrowding and delays. The implementation of these tools is complicated by the potential risks associated with over-triage and under-triage, untraceable false positives, as well as the potential for the biases of (...) healthcare professionals toward technology leading to the incorrect usage of such tools. This paper explores risk surrounding these issues in an analysis of a case study involving a machine learning triage tool called the Score for Emergency Risk Prediction (SERP) in Singapore. This tool is used for estimating mortality risk in presentation at the ED. After two successful retrospective studies demonstrating SERP’s strong predictive accuracy, researchers decided that the pre-implementation randomised controlled trial (RCT) would not be feasible due to how the tool interacts with clinical judgement, complicating the blinded arm of the trial. This led them to consider other methods of testing SERP’s real-world capabilities, such as ongoing-evaluation type studies. We discuss the outcomes of a risk–benefit analysis to argue that the proposed implementation strategy is ethically appropriate and aligns with improvement-focused and systemic approaches to implementation, especially the learning health systems framework (LHS) to ensure safety, efficacy, and ongoing learning.

In this essay I enter into a recently published debate between Stephen Schiffer and Jerry Fodor concerning whether adequate sense can be made of the ceteris paribus conditions in special science laws, much of their focus being on the case of putative psychological laws. Schiffer argues that adequate sense cannot be made of ceteris paribus clauses, while Fodor attempts to overcome Schiffer's arguments, in defense of special science laws. More recently, Peter Mott has attempted to show that Fodor's response (...) to Schiffer fails, and furthermore that further study shows that the logical framework in which Schiffer and Fodor address their issue is susceptible to inconsistency.In this essay I argue that adequate sense can be made of ceteris paribus conditions. Against Mott, I argue that recent work in the model theory of non-monotonic logic indicates how his problem involving logical inconsistencies can be overcome. Against Schiffer, I argue that the claims that he makes against ceteris paribus clauses would lead to a fatal skepticism concerning indefinitely many of the claims we make about the world (and indeed that his claims would be destructive of the view of the special sciences that Schiffer himself presents in his paper), and that the semantical considerations from non-monotonic logic that I present provide a suitable framework for dealing with his complaints. Thus I come out on the whole on Fodor's side of this debate, although for my own reasons, as I argue against much of Fodor's own argumentation. (shrink)

In his book Why Not Socialism?, G.A. Cohen described several kinds of inequality that would be acceptable under socialism, yet nonetheless harmful to community. I describe another kind of inequality with this property, deriving from the legitimate transmission of preferences and values from parents to children. In the same book, Cohen proposes that the designing of a socialist allocation mechanism is a key problem for socialist theory. I maintain this is less of a problem than he believes. Finally, some thoughts (...) on the “law of motion of socialist ethos” are offered. (shrink)

In his enormously influentialThe Modularity of Mind, Jerry Fodor (1983) proposed that the mind was divided into input modules and central processes. Much subsequent research focused on the modules and whether processes like speech perception or spatial vision are truly modular. Much less attention has been given to Fodor's writing on the central processes, what would today be called higher‐level cognition. In “Fodor's First Law of the Nonexistence of Cognitive Science,” he argued that central processes are “bad candidates for (...) scientific study” and would resist attempts at empirical analysis. This essay evaluates his argument for this remarkable claim, concluding that although central processes may well be “messier” than input modules, this does not mean that they cannot be studied and understood. The article briefly reviews the scientific progress made in understanding central processes in the 35 years since the book was published, showing that Fodor's prediction is clearly falsified by massive advances in topics like decision making and analogy. The essay concludes that Fodor's Law was not based on a clear argument for why the complexities of central systems could not be studied but was likely based on intuitions and preferences that were common in psychology at the time.

Cognitive science has come down with a nasty cold, so Jerry Fodor has recently lamented, and the afflicting strain is something called concept pragmatism.1 Its chief symptom is the urge to identify the content of a concept with the inferences habitually drawn upon in its use (a ‘definition-in-use’), these serving also as its condition of possession, in knowing how to draw those inferences definitive of the concept.2 The affliction is quite fatal if Fodor is right, but the welfare of (...) the patient is of only indirect concern.

Persons who commit crimes involving sexual abuse of children exploit their victims in several ways. Sex offenders use their power and authority over vulnerable children to whom they have easy access. Teachers, coaches, clergy, family members and childcare workers have been exposed as sex offenders. The Pennsylvania State University football coach, Jerry Sandusky, is now in prison for his many crimes. The widespread cover up of sexual abuse by Catholic priests in the USA and other countries is a horrendous (...) scandal. It is not surprising that law enforcement, mental health professionals, victims and their families are outraged. It is no surprise that radical interventions such as chemical or surgical castration are a response to the public pressure to protect children from molestation.I agree with Professor John McMillan's thoughtful discussion and nuanced analysis of surgical castration.1i He concludes that surgical castration of sex offenders is ethically permissible if these conditions are met: Castration should be requested by the sex offender. Informed consent from a competent sex offender is required. Consent to castration must not be coerced via threats or inducements.He also says that “castration might be useful for the reconfiguring of a life that has gone badly awry.”To supplement his discussion I will describe a state law in Texas2 that permits voluntary surgical castration for repeat child molesters while they are incarcerated as ….

In (1990), Jerry Fodor has defended a naturalized conception of meaning for Mentalese expressions which relies on the notion of asymmetric dependence. According to this conception, any naturalized theory of meaning must be able to account for the fact that meaning is robust, namely that any token of a certain Mentalese expression “x” retains the expression’s meaning, X, for any Y (≠ X) which happens to cause it. Now, this robustness of “x”‘s meaning can precisely be explained in terms (...) of the subsistence of an asymmetric dependence of any nomic connection between Ys and “x”‘s tokens on another nomic connection between Xs and “x”‘s tokens. According to Fodor, then, this relation between nomic connections can account in perfectly naturalistic terms for “x” meaning X, by providing a sufficient condition for such a meaning. In what follows, however, I will try to show, first, that the subsistence of asymmetric dependencies of the kind envisaged by Fodor is not enough for assigning meaning to a certain expression. Indeed, there are dependencies of this kind which are meaning-irrelevant. Secondly, I will claim that asymmetric dependence relations are not able even to support for the robustness of meaning. For there are cases in which according to the structure of these relations we would have to conclude that meaning is altered although robustness would require to have it unchanged. (shrink)

Seinfeld (1989–1998) and it’s co-creator’s Curb Your Enthusiasm (2000–present), are each considered groundbreaking television. Critics regard their humor and intellectual comedy as Twain-like and creative. While both shows have been criticized for their character’s indifference and apolitical attitude, the programs resonate with those in society who more subtly consider law and politics. This project argues that Seinfeld and Curb present a unique theory of justice. These two shows constitute a common and current image of what is just in society. While (...) critics have argued that Seinfeld and Curb are not shows about nothing, I argue that these comedians offer us a legal philosophy. For those who view these characters as merely “self-absorbed, superficial, and immature,” I posit that they represent the obscure area between what John Locke termed “the state of nature” and what legal scholars call “legal culture.” I propose that these sitcoms demonstrate a way of speaking about law that provides a constitutive theory of law and justice.

Jerry Fodor has long championed the view, recently dubbed “scientific intentional realism” (Loewer and Ray, 1991, p. xiv), that “a scientifically adequate psychology will contain laws that quantify over intentional phenomena in intentional terms.” On such a view our belief/desire psychology will be “vindicated” through empirical investigation; that is, it will be shown to denote the explanatory (or causally salient) states or events in the production of thought and behavior. That intentional properties, states, or events have causal efficacy---are not (...) mere epiphenomena---is necessary for any such vindication. This paper investigates whether intentional properties can if fact ground or sustain the causal relations empirical psychology aims to reveal. I conclude that intentional properties are not amenable to such an explanatory role, and that, therefore, a different vindication of intentional description is required of the realist. (shrink)

Jerry Fodor has defended the claim that psychological theories should appeal to narrow rather than wide intentional properties. One of his arguments relies upon the cross contexts test, a test that purports to determine whether two events have the same causally relevant properties. Critics have charged that this test is too weak, since it counts certain genuinely explanatory relational properties in science as being causally irrelevant. Further, it has been claimed, the test is insensitive to the fact that special (...) scientific laws allow for exceptions which do not undermine those laws. This paper refines the cross contexts test to meet these objections while still allowing it to play its role in Fodor. (shrink)

In the current dialogue of “science and religion,” it is widely assumed that the thoughts of Darwinists and that of atheists overlap. However, Jerry Fodor, a full-fledged atheist, recently announced a war against Darwinism with his atheistic campaign. Prima facie, this “civil war” might offer a chance for theists: If Fodor is right, Darwinistic atheism will lose the cover of Darwinism and become less tenable. This paper provides a more pessimistic evaluation of the situation by explaining the following: Fodor’s (...) criticism of adaptationism (as the backbone of Darwinism), viz., his refutation of any counterfactual-supporting laws on the macro-evolutionary level, implies that a law-maker is dispensable on this level. This will either encourage skepticism against the omniscience (at least that concerning the future of macro-evolution) of the Creator, or render the notion of God less appealing. (shrink)

Jerry Fodor has argued that the multiple realizability argument, as discussed in his original “Special Sciences” article, “refutes psychophysical reductionism once and for all.” I argue that his argument in “Special Sciences” does no such thing. Furthermore, if one endorses the physicalism that most supporters of the “Special Sciences” view endorse, special science laws must be reducible, in principle. The compatibility of MR with reduction, however, need not threaten the autonomy of the special sciences.

Professor Cohen, 'Jerry' to very many, has been Chichele Professor of Social and Political Theory, All Souls College, Oxford.

The main topic of Jerry Fodor’s The Elm and the Expert,1, and the title of the first chapter, is “If Psychological processes are computational, how can psychological laws be intentional?” I focus on the first and second chapters; The first is devoted to setting up the question, the second to answering it.

With the aim of giving a naturalistic foundation to the notion of mental representation, Fred Dretske (1981;1988) has put forward and developed the idea that the relation between a representation and its intentional content is grounded on an informational relation. In this explanatory model, mental representations are conceived of as states of organisms which a learning process has selected to play a functional role: a necessary condition for fulfilling this role is that the organism or some proper part of it (...) (presumably situated in the brain) is a natural indicator of the occurrence of a determinate type of event in the environment of the organism (or in the organism but outside of the proper part serving as the indicator). A state of the organism is a natural indicator of a type of event if and only if it carries information about the occurrence of that type of event. Jerry Fodor (1987) has devised and followed another strategy which consists in considering the relation between a mental representation and its intentional object as a relation of lawful, or nomic, dependence. A representational state of an organism has an objective content in virtue of the existence of a relation of nomic dependence between this state - presumably a property of the brain of the organism - and some objective property in the world. This dependence also creates a regular correlation between the occurrences of representational states of a certain type and the states of affairs whose type is their representational content. Both approaches encounter indeterminacy problems: for each, there exist situations in which the explanatory model chosen - information flow or nomic dependence - does not succeed in selecting, purely on the basis of the constraints characteristic of that model, one out of several potential contents for a given representational state. In such cases, that state is related to more than one type of events in accordance with the informational or nomic constraints imposed by those theories. In what follows, I examine an attempt by Pierre Jacob (1997) to solve two problems of indeterminacy threatening the informational theory of mental representation. According to Jacob, one of these problems can be solved with the help of the distinction between the source which is the target of the information and the channel over which the information is transmitted, whereas the solution to the other problem requires the introduction of the concept of function. I shall begin with a consideration of the distinction, with respect to a situation of information transmission, between the source and the channel. I argue that both the source and the channel, and thus the information transmitted, depend not only on the external situation which characterises the source, the channel and the receiving organism, but also on the previous knowledge and the informational needs of the receiver. I then try to show that this relativity of information undermines the solution Jacob proposes to one of the problems of indeterminacy of representational content. Finally, I examine the possibility considered by Dretske and Jacob to solve this 'problem of the reference class' due to the mentioned relativity of information, by grounding the flow of information on lawful dependence instead of statistical dependence. I shall propose two arguments showing first that these two groundings are not equivalent and second that nomic dependence is inappropriate as a grounding for information flow. I conclude by suggesting that the problem of the reference class can be solved within the framework of the informational approach, on the condition of enriching it with functional considerations.

A major obstacle to formulating a broad-content intentional psychology is the occurrence of ''Frege cases'' - cases in which a person apparently believes or desires Fa but not Fb and acts accordingly, even though "a" and "b" have the same broad content. Frege cases seem to demand narrow-content distinctions to explain actions by the contents of beliefs and desires. Jerry Fodor ( The elm and the expert: Mentalese and its semantics , Cambridge, MA: MIT Press, 1994) argues that an (...) explanatorily adequate broad-content psychology is nonetheless possible because Frege cases rarely occur in intentional-explanatory contexts, and they are not systematically linked to intentional laws in a way that demands intentional explanation. Thus, he claims, behaviors associated with Frege cases can be considered ceteris-paribus exceptions to broad-content intentional laws without significantly decreasing the explanatory power of intentional psychology. I argue that Frege cases are plentiful and systematically linked to intentional laws in a way that requires intentional explanation, specifically in the explanation of why certain actions are not performed. Consequently, Frege-case behaviors cannot be construed as ceteris-paribus exceptions to intentional laws without significantly eroding the explanatory power of intentional psychology and reducing the rationality of the agent. Fodor thus fails to save broad-content psychology from the prima facie objections against it based on Frege cases. (shrink)
