From late 1684 through mid-1685, Isaac Newton turned to developing and refining the conceptual foundations presupposed by his emerging physics. Analysis of his manuscripts from this period reveals that Newton’s understanding of the relativity of acceleration led him to seek a spatiotemporally invariant quantity of matter. He found two such quantities and then designed an experiment to discover their relationship. Interpreting the experiment, however, required distinguishing a new notion of force. Others have recognized the conceptual distinction between inertial and gravitational (...) mass. I show here that Newton clearly saw this distinction and that he provisionally established their equivalence. (shrink)

Richard Miller presents a bold new program for international justice. He argues for new standards of responsible conduct by governments, firms, and individuals in developed countries, to govern trade, investment, environmental policy, and the use of force. He offers an urgently needed strategy for moving humanity toward genuine global co-operation.

Hegel is an immensely important yet difficult philosopher. His Philosophy of Mind is one of the main pillars of his thought. Michael Inwood, highly respected for his previous work on Hegel, presents this central work to the modern reader in an accurate new translation supported by a philosophically sophisticated editorial introduction and elucidating scholarly commentary.

Andrews et al. attempt to clarify the standards for determining whether traits are adaptations. The authors argue that tests of adaptationist hypotheses best proceed by assessing the consistency of the traits with the proposed standards. Critical tests of such standards must assess inconsistency – hypotheses must be falsifiable. To fully understand trait evolution, we must consider both adaptive and nonadaptive hypotheses.

In an influential series of papers, Cleland (2001, 2002, 2011) argued that historical natural scientists employ a distinctive methodology—which exploits Lewis (1979)s asymmetry of over determination—that is capable of putting knowledge of the deep past on an epistemic par with experimental knowledge. Currie (2018) clarified the nature of the asymmetry claim and used it to argue for a more restricted form of optimism toward the historical sciences. This optimism is licensed by the evidential redundancy that the asymmetry of over determination (...) guarantees.In this chapter I show that the argument for the asymmetry of over determination is circular and the thesis is false. Over determination toward the past is smuggled in from the start by ruling out of consideration so-called backtracking counterfactuals. By banning backtracking counterfactuals, consideration is restricted to possible worlds in which the over determination thesis holds. But in the actual world, the present is compatible with many different histories. (shrink)

Ordinary equational logic is a connective-free fragment of first-order logic which is concerned with total functions under the relation of ordinary equality. In [AN] (see also [AN1]) and in [Cr] it has been extended in two equivalent ways into a near-equational system of logic for partial functions. The extension given in [Cr] deals with partial functions under two relationships: a relationship of existence-dependent existence and one of existence-dependent Kleene equality. For the language that involves both relationships a set of rules (...) was given that is complete. Those rules in the set that involve only existence-dependent existence turned out to be complete for the sublanguage that involves this relationship only. In the present paper we give a set of rules that is complete for the other sublanguage, namely the language of partial functions under existence-dependent Kleene equality.This language lacks a certain, often needed, power of expressing existence and fails, in particular, to be an extension of the language that underlies ordinary equational logic. That it possesses a fairly simple complete set of rules is therefore perhaps more of theoretical than of practical interest. The present paper is thus intended to serve as a supplement to [Cr] and, less directly, to [AN]. The subject is further rounded out, and some contrast is provided, by [Rob]. The systems of logic treated there are based on the weaker language in which partial functions are considered under the more basic relation of Kleene equality. (shrink)

In this article I will identify the position from which I write and the methodology I will employ, and then I will ask: ”Is the Foucauldian conception of disciplinary power still at work in contemporary forms of imprisonment?” I will answer this question in the affirmative and report the results of a case study of the operational philosophy of a contemporary prison in Melbourne Australia while highlighting some key comparative points from Discipline and Punish . How prisoners resist and subvert (...) disciplinary power by turning an inclusive grouping within the prison into a site from which they highly differentiate Self from Other will be touched upon. I will conclude by finding that homo criminalis has in fact become a definite object in the field of knowledge and he is emerging as a product from the machine for altering minds. (shrink)

This essay examines several recent philosophical attempts to define ‘disease’. Two prominent ones are considered in detail, an objective approach by Christopher Boorse and a normative approach by Caroline Whitbeck. Both are found to be inadequate for a variety of reasons, though Whitbeck's is superior because of her careful preliminary distinctions and because of its normative approach which is more nearly in accord with medical and lay usage. The paper concludes with a discussion of the nature of such efforts at (...) definition and suggests that their limitations are due both to the nature of our language and concepts in general, and to the nature of medicine in particular. It is the practical and changing character of medicine and its language that frustrates the efforts of philosophers to formulate such definitions.

Purpose – This paper aims to explore similarities and differences between robots, invasive biological species, and genetically modified organisms. These comparisons are designed to better understand the potential effects of robots on human society. Design/methodology/approach – This paper applies established ideas in one discipline – biology – to issues that are less well understood, but actively being studied in another discipline – science and technology studies. Findings – Robots entering human society in large numbers share many of the characteristics of (...) an invasive species entering a new ecosystem. The authors also find that robots have several characteristics that are similar to a genetically modified organism. Taken together, these similarities suggest that society should be cautious about the introduction of large numbers of robots in a short period of time. Originality/value – The approach taken here to assess robots in society by these analogies to ecological processes is, to the authors' knowledge, novel. Applying ideas from a better-known area to a less well-known area is routine in philosophy, but these particular analogies have not yet been carefully articulated in the literature. (shrink)

In their important paper “Autonomous Agents”, Floridi and Sanders use “levels of abstraction” to argue that computers are or may soon be moral agents. In this paper we use the same levels of abstraction to illuminate differences between human moral agents and computers. In their paper, Floridi and Sanders contributed definitions of autonomy, moral accountability and responsibility, but they have not explored deeply some essential questions that need to be answered by computer scientists who design artificial agents. One such question (...) is, “Can an artificial agent that changes its own programming become so autonomous that the original designer is no longer responsible for the behavior of the artificial agent?” To explore this question, we distinguish between LoA1 (the user view) and LoA2 (the designer view) by exploring the concepts of unmodifiable, modifiable and fully modifiable tables that control artificial agents. We demonstrate that an agent with an unmodifiable table, when viewed at LoA2, distinguishes an artificial agent from a human one. This distinction supports our first counter-claim to Floridi and Sanders, namely, that such an agent is not a moral agent, and the designer bears full responsibility for its behavior. We also demonstrate that even if there is an artificial agent with a fully modifiable table capable of learning* and intentionality* that meets the conditions set by Floridi and Sanders for ascribing moral agency to an artificial agent, the designer retains strong moral responsibility.

As a way to make medical decisions, Evidence-Based Medicine (EBM) has failed. EBM's failure arises from not being founded on real-world decision-making. EBM aspires to a scientific standard for the best way to treat a disease and determine its cause, but it fails to recognise that the scientific method is inapplicable to medical and other real-world decision-making. EBM also wrongly assumes that evidence can be marshaled and applied according to an hierarchy that is determined in an argument by authority to (...) the method by which it has been obtained. If EBM had valid theoretical, practical or empirical foundations, there would be no hierarchy of evidence. In all real-world decision-making, evidence stands or falls on its inherent reliability. This has to be and can only be assessed on a case-by-case basis applying understanding and wisdom against the background of all available facts—the "factual matrix." EBM's failure is structural and was inevitable from its inception. EBM confuses the inherent reliability and probative value of evidence with the means by which it is obtained. -/- EBM is therefore an ad hoc construct and is not a valid basis for medical decision-making. This is further demonstrated by its exclusion of relevant scientific and probative real-world decision-making evidence and processes. It draws upon a narrow evidence base that is itself inherently unreliable. It fails to take adequate account of the nature of causation, the full range of evidence relevant to its determination, and differing approaches to determining cause and effect in real-world decision-making. EBM also makes a muddled attempt to emulate the scientific method and it does not acknowledge the role of experience, understanding and wisdom in making medical decisions. (shrink)

A general obligation to make aggregate research results available to participants has been widely supported in the bioethics literature. However, dementia research presents several challenges to this perspective, particularly because of the fear associated with developing dementia. The authors argue that considerations of respect for persons, beneficence, and justice fail to justify an obligation to make aggregate research results available to participants in dementia research. Nevertheless, there are positive reasons in favor of making aggregate research results available; when the decision (...) is made to do so, it is critical that a clear strategy for communicating results is developed, including what support will be provided to participants receiving aggregate research results.

Medicine, like law, is a pragmatic, probabilistic activity. Both require that decisions be made on the basis of available evidence, within a limited time. In contrast to law, medicine, particularly evidence-based medicine as it is currently practiced, aspires to a scientific standard of proof, one that is more certain than the standards of proof courts apply in civil and criminal proceedings. But medicine, as Dr. William Osler put it, is an "art of probabilities," or at best, a "science of uncertainty." (...) One can better practice medicine by using other evidentiary standards in addition to the "scientific." To employ only the scientific standard of proof is inappropriate, if not impossible; furthermore, as this review will show, its application in medicine is fraught with bias. Evidence is information. It supports or undermines a proposition, whether a hypothesis in science, a diagnosis in medicine, or a fact or point in question in a legal investigation. In medicine, physicians marshal evidence to make decisions on how to best prevent, diagnose, and treat disease, and improve health. In law, courts decide the facts and render justice. Judges and juries assess evidence to establish liability, to settle custody and medical issues, and to determine a defendant's guilt or innocence. (shrink)

This article reports four subliminal perception experiments using the relationship between confidence and accuracy to assess awareness. Subjects discriminated among stimuli and indicated their confidence in each discrimination response. Subjects were classified as being aware of the stimuli if their confidence judgments predicted accuracy and as being unaware if they did not. In the first experiment, confidence predicted accuracy even at stimulus durations so brief that subjects claimed to be performing at chance. This finding indicates that subjects's claims that they (...) are ''just guessing'' should not be accepted as sufficient evidence that they are completely unaware of the stimuli. Experiments 2-4 tested directly for subliminal perception by comparing the minimum exposure duration needed for better than chance discrimination performance against the minimum needed for confidence to predict accuracy. The latter durations were slightly but significantly longer, suggesting that under certain circumstances people can make perceptual discriminations even though the information that was used to make those discriminations is not consciously available.
