In this book, I give a topic-based, modular introduction to philosophy. The book has 16 chapters: 7 in theoretical philosophy and 9 in practical philosophy. Each topic is introduced by means of a concrete question; the main positions on this question are then developed and criticized in turn. I try to avoid taking sides; instead, I emphasize that students must think through the issues for themselves.

In this paper I argue that there would be no obligatory maxims if the only standards for assessing maxims were Kant’s universalizability tests. The paper is divided into five sections. In the first, I clarify my thesis: I define my terms and disambiguate my thesis from other related theses for which one might argue. In the second, I confront the view that says that if a maxim passes the universalizability tests, then there is a positive duty to adopt that maxim; (...) I also confront a close relative of this view. In the third, I confront the view that says that if a maxim does not pass the universalizability tests, then there is a positive duty to adopt the contradictory of that maxim. In the fourth, I confront two variations of the view that says that if a maxim does not pass the universalizability tests and an agent is deliberating about the action in the maxim, then the agent has a positive duty to adopt the contrary of that maxim. In the fifth, I confront the view that says that if an agent has adopted a maxim of ends, then the agent has a positive duty to universalize that end. I then wrap up the paper with some concluding remarks. (shrink)

In this paper I intend to raise a problem for so-called Frankfurt examples. I begin by describing the examples and what they are used for. Then I describe the problem.

In this paper I defend the traditional interpretations of Kant’s Formula of a Law of Nature from recent attacks leveled by Faviola Rivera-Castro, James Furner, Ido Geiger, Pauline Kleingeld and Sven Nyholm. After a short introduction, the paper is divided into four main sections. In the first, I set out the basics of the three traditional interpretations, the Logical Contradiction Interpretation, the Practical Contradiction Interpretation and the Teleological Contradiction Interpretation. In the second, I examine the work of Geiger, Kleingeld and (...) Nyholm: these three commentators reject the traditional interpretations entirely, but I argue that this rejection is ill-founded. In the third and fourth, I take a detailed look at Furner’s work, work in which he seeks to revise (rather than reject) the traditional interpretations. I argue that, despite his more modest aims, Furner’s revision is also ill-founded. (shrink)

In this article, I explore an important difference between circumstantial luck on the one side and resultant and constitutive luck on the other. In section 1, I argue that, in circumstantial luck, the object of luck and the object of moral judgment are different even though, in resultant and constitutive luck, they are the same. In section 2, I explain that this difference (1) has the potential to undermine the regress argument for moral luck; (2) makes viable the “selective moral (...) luck” argument strategy (affirming some species of moral luck but denying others); and (3) has implications for the heritability of luck.

The purpose of this paper is to show that, if Kant’s universalization formulations of the Categorical Imperative are our only standards for judging right from wrong and permissible from impermissible, then we have no obligations. I shall do this by examining five different views of how obligations can be derived from the universalization formulations and arguing that each one fails. I shall argue that the first view rests on a misunderstanding of the universalization formulations; the second on a misunderstanding of (...) the concept of an obligation; the third on a misunderstanding of the concept of a maxim; the fourth on a misunderstanding of the limits of action description; and the fifth on a misunderstanding of the universalization formulations again.

Many take Kantian ethics to founder when it comes to our duties to animals. In this paper, I advocate a novel approach to this problem. The paper is divided into three sections. In the first, I canvass various passages from Kant in order to set up the problem. In the second, I introduce a novel approach to this problem. In the third, I defend my approach from various objections. By way of preview: I advocate rejecting the premise that nonhuman animals (...) are nonrational. (shrink)

In this article, I argue that Kant’s Categorical Imperative applies to maxim tokens rather than to maxim types. The article has three main parts. In the first, I explain my thesis. In the second, I argue for it. In the third, I argue, further, that, if my thesis is correct, then tokens of different maxim types can have different deontic statuses for different agents.

In a series of well known publications, Christine Korsgaard argues for the claim that an agent acts morally just in case s/he acts autonomously. Two of Korsgaard's signature arguments for the connection between morality and autonomy are the "argument from spontaneity" and the "regress argument." In this paper, I argue that neither the argument from spontaneity nor the regress argument is able to show that an agent would be acting wrongly even if s/he acts in a paradigmatically heteronomous fashion.

According to the positive duties objection, it is not possible to derive positive duties from Kant’s Formula of Universal Law (FUL). However, in his recent “Deriving Positive Duties from Kant’s Formula of Universal Law”, Guus Duindam tries to answer this objection. More specifically, Duindam tries to show how both a duty of benevolence and a duty of self-perfection can be derived from the FUL. I critically examine Duindam’s arguments. I maintain that Duindam’s argument for the positive duty of benevolence is (...) ambiguous and that this ambiguity exposes him to a fatal dilemma: on one horn, Duindam faces the same objection that he concedes to be effective against other attempts to answer the positive duties objection; on the other horn, the procedure he recommends cannot be based on the FUL (because it does not evaluate actions on the basis of their corresponding maxims). In addition, I maintain that Duindam’s benevolence argument rests on a procedure that is, in general, intractable and, in this particular case, foredoomed (because it can be shown that there are no positive duties of the kind he tries to derive). From there, I turn to Duindam’s argument for the positive duty of self-perfection. I explain that Duindam’s derivation of the duty of self-perfection, even if successful, does not answer the positive duties objection. This is because Duindam never appeals to the FUL in his derivation of the duty of self-perfection (the derivation is based, rather, on instrumental reasoning from the second-order end to accomplish our first-order ends). I elaborate on this by comparing and contrasting Duindam’s argument with Oliver Sensen’s interpretation of how to apply the FUL in the latter’s recent “Universal Law and Poverty Relief”. (shrink)

In this paper I discuss Kant’s theory of conscience. In particular, I explicate the following two claims that Kant makes in the Metaphysics of Morals: (1) an erring conscience is an absurdity and (2) if an agent has acted according to his/her conscience, then s/he has done all that can be required of him/her. I argue that (1) is a very specific claim that does not bear on the problem of moral knowledge. I argue that (2) rests on a strongly (...) internalist line of argument. (shrink)

In this article, I confront Jessica Flanigan’s recent attempt to show not merely that women have a right to commit prenatal injury, but also that women who act on this right are praiseworthy and should not be criticized for this injury. I show that Flanigan’s arguments do not work, and I establish presumptive grounds against any such right—namely, prenatal injury, by definition, involves intentional or negligent harm and, as such, may be subsumed under a wider class of actions that are (...) presumptively wrong. (shrink)

According to Kant, if an agent acts according to his/her conscience, then s/he has done all that s/he ought as far as morality is concerned. But Kant thinks that agents can be mistaken in their subjective determinations of their duties. That is, Kant thinks it is possible for an agent to believe that some action X is right even though it is an objective truth that X is not right; according to Kant, agents do not have infallible knowledge of right (...) and wrong. In this paper, I explore this doctrine in order to determine whether it is defensible. In particular, I confront the blameworthiness of acting contrary to fallible knowledge and the blamelessness of acting according to fallible judgment. (shrink)

In Bencivenga’s “Consequences in Kantian Ethics,” he offers a version of Kant’s ethics according to which the most rational approach to living one’s life is “to always imagine what might follow from one’s moves and to choose moves accordingly” (284), but according to which agents always nevertheless must be modest in their judgments about what they ought to do because the actual consequences of their actions might not turn out as they imagined. In this way, he tries to foreground the (...) role of consequences in Kant's ethics. In this paper, I argue against Bencivenga and, in particular, against the idea that according to Kant, to determine whether an agent’s action is good we must wait for its consequences to unfold in time.

Traditional accounts of the emergence of professional biology have privileged not only metropolis over province, but research over teaching and laboratory over museum. This paper seeks to supplement earlier studies of the ‘transformation of biology’ in the late nineteenth century by exploring in detail the developments within three biology departments in Northern English civic colleges. By outlining changes in the teaching practices, research topics and the accommodation of the departments, the authors demonstrate both locally contingent factors in their development and (...) continuities with existing traditions in natural history. The appointment of Arthur Milnes Marshall in preference to Louis Miall to the new zoology chair in Manchester in 1879 casts light on contemporary views of the laboratory and museum as ‘equal though different’. The transformation in biology, in Northern England at least, was shaped more by such local institutional changes than by a phoenix-like rise of the laboratory from the ashes of the museum—more by the rhetorical construction of a professional academic community than any dramatic shift in sites. In this period the biology laboratory supplemented, rather than eclipsed, the museum, and the dichotomy between the ‘naturalist’ and the ‘experimentalist’ was far from clear-cut. (shrink)

My goals in this paper are twofold: to outline the refashioning of amateur and professional roles in life science in late Victorian Yorkshire, and to provide a revised historiography of the relationship between amateurs and professionals in this era. Some historical treatments of this relationship assume that amateurs were demoralized by the advances of laboratory science, and so ceased to contribute and were left behind by the autonomous "new biology." Despite this view, I show that many amateurs played a vital (...) part in the construction of a professional academic community in urban Yorkshire, and then continued to collaborate with the laboratory-based biologists. The key to any analysis of the relationship between amateurs and professionals is the great variety of amateur identities and practices in Victorian Yorkshire. The amateur-professional rift fallacy arose because laboratory biologists fashioned an identity in conscious opposition to a particular type of amateur: an ideal that belied an array of cooperative relationships. As naturalists refashioned their roles and identities in light of the changes within academe and without, debates about the practice and place of life science took place as often among amateurs as between professionals and amateurs.

Samuel Kerstein’s recent (2013) How To Treat Persons is an ambitious attempt to develop a new, broadly Kantian account of what it is to treat others as mere means and what it means to act in accordance with others’ dignity. His project is explicitly nonfoundationalist: his interpretation stands or falls on its ability to accommodate our pretheoretic intuitions, and he does an admirable job of handling carefully a range of well fleshed out and sometimes subtle examples. In what follows, (...) I shall give a quick summary of the chapters and then say two good things about the book and one critical thing. (shrink)

This survey outlines a history of museums written through biographies of objects in their collections. First, the mechanics of the movement of things and the accompanying shifts in status are considered, from manufacture or growth through collecting and exchange to the museum. Objects gathered meanings through associations with people they encountered on their way to the collection, thus linking the history of museums to broader scientific and civic cultures. Next, the essay addresses the use of items once they joined a (...) collection, whether classificatory, analytical, or in display. By thus embedding the study of scientific practice in material culture, this approach contributes to constructivist histories of science. The final section addresses the role of objects in the experience of the visitors, emphasizing how fruitful the history of museum objects can be in the study of the public engagement with science.

The prospect of using cell-based interventions to treat neurological conditions raises several important ethical and policy questions. In this target article, we focus on issues related to the unique constellation of traits that characterize CBIs targeted at the central nervous system. In particular, there is at least a theoretical prospect that these cells will alter the recipients' cognition, mood, and behavior—brain functions that are central to our concept of the self. The potential for such changes, although perhaps remote, is cause (...) for concern and careful ethical analysis. Both to enable better informed consent in the future and as an end in itself, we argue that early human trials of CBIs for neurological conditions must monitor subjects for changes in cognition, mood, and behavior; further, we recommend concrete steps for that monitoring. Such steps will help better characterize the potential risks and benefits of CBIs as they are tested and potentially used for treatment. (shrink)

We are printing, by kind permission of the Law Commission, two sections of the report of the Law Commission on injuries to unborn children. This report was the result of a request to the Law Commission by the Lord Chancellor at the time (Lord Hailsham of Saint Marylebone) to advise on `what the nature and extent of civil liability for antenatal injury should be'. The Law Commission followed its usual practice in such circumstances of consulting various bodies and obtaining expert (...) advice on the subject and then embodying the results in a working paper (Working Paper No. 47 - injuries to unborn children) published on 19 January 1973, which preceded their report (Cmnd 5709). Meanwhile a Royal Commission is considering much wider issues of civil liability for injury (including antenatal injury) but the terms of reference for the Law Commission were much narrower and confined to the position of children injured before birth. In the section relating to the present law the report makes it clear that it is probable that liability under the common law already exists. The Scottish Law Commission has also issued a report (Cmnd 5371). They were given different terms of reference and came to somewhat different conclusions. We are printing from this long report the paragraphs discussing the medical background and the summary of recommendations. As will be evident on reading the paragraphs on the medical background to injuries to the unborn child, events are moving very rapidly, particularly in the study of congenital defects and the effects of drugs but the problems of proof present great difficulty. Other causes of injury to the unborn child are better known to the general public: for example, those following the illness, infection and disease of the mother during pregnancy, injury caused in attempted termination of pregnancy and the risks resulting from the mother's condition. The summary of the recommendations sets out very clearly the legal position of the unborn child, as the Law Commission sees it, arising from injury before birth, the final conclusion being that `legislation is desirable'. These extracts from the report, apart from their intrinsic interest, lead on to the paper by Mr Kennedy and Dr Edwards in which they set out their criticisms of it, and provide quick references to the original document.

Knowledge of eukaryotic life cycles and associated genome dynamics stems largely from research on animals, plants, and a small number of “model” (i.e., easily cultivable) lineages. This skewed sampling results in an underappreciation of the variability among the many microeukaryotic lineages, which represent the bulk of eukaryotic biodiversity. The range of complex nuclear transformations that exists within lineages of microbial eukaryotes challenges the textbook understanding of genome and nuclear cycles. Here, we look in‐depth at Foraminifera, an ancient (∼600 million‐year‐old) lineage (...) widely studied as proxies in paleoceanography and environmental biomonitoring. We demonstrate that Foraminifera challenge the “rules” of life cycles developed largely from studies of plants and animals. To this end, we synthesize data on foraminiferal life cycles, focusing on extensive endoreplication within individuals (i.e., single cells), the unusual nuclear process calledZerfall, and the separation of germline and somatic function into distinct nuclei (i.e., heterokaryosis). These processes highlight complexities within lineages and expand our understanding of the dynamics of eukaryotic genomes. (shrink)

Although Machiavelli was never a military commander, he was throughout much of his life deeply concerned with the conduct of martial affairs; in short, a Renaissance Herman Kahn. This book is an essay on the technique of war: how on army is organized, who make the best soldiers, field manœuvers and battle formations, logistics, internal stability and control of military units, techniques of siege; these are considered both historically with reference to the ancients, as well as the present—the contemporary (...) applications of these techniques in the author's own time. The editor has provided a long critical and historical introduction—amounting to a small monograph in itself—which helps to place Machiavelli's ideas in the tradition of military-political theorists of Western Europe.—P.

Nanomedicine is yielding new and improved treatments and diagnostics for a range of diseases and disorders. Nanomedicine applications incorporate materials and components with nanoscale dimensions where novel physiochemical properties emerge as a result of size-dependent phenomena and high surface-to-mass ratio. Nanotherapeutics and in vivo nanodiagnostics are a subset of nanomedicine products that enter the human body. These include drugs, biological products, implantable medical devices, and combination products that are designed to function in the body in ways unachievable at larger scales. (...) Nanotherapeutics andin vivonanodiagnostics incorporate materials that are engineered at the nanoscale to express novel properties that are medicinally useful. These nanomedicine applications can also contain nanomaterials that are biologically active, producing interactions that depend on biological triggers. Examples include nanoscale formulations of insoluble drugs to improve bioavailability and pharmacokinetics, drugs encapsulated in hollow nanoparticles with the ability to target and cross cellular and tissue membranes and to release their payload at a specific time or location, imaging agents that demonstrate novel optical properties to aid in locating micrometastases, and antimicrobial and drug-eluting components or coatings of implantable medical devices such as stents.

This article argues the philosophical concerns and foundational challenges raised by a for-profit model of education. The for-profit model is governed by a business paradigm, without reference to the context in which it is found. The authors explore primary ethical questions and challenges presented by this model. As such, they present potential solutions to the growing problem in higher education as a corporate entity. The authors introduce a potential model for analysis of the issues and suggest an interventional technique with (...) concrete directions for change. Universities are on the threshold of a transformation which can no longer be isolated from wider society. This environment awakened the critical task of blending corporate success with educational integrity. (shrink)

Recent progress in artificial intelligence has renewed interest in building systems that learn and think like people. Many advances have come from using deep neural networks trained end-to-end in tasks such as object recognition, video games, and board games, achieving performance that equals or even beats that of humans in some respects. Despite their biological inspiration and performance achievements, these systems differ from human intelligence in crucial ways. We review progress in cognitive science suggesting that truly human-like learning and thinking (...) machines will have to reach beyond current engineering trends in both what they learn and how they learn it. Specifically, we argue that these machines should build causal models of the world that support explanation and understanding, rather than merely solving pattern recognition problems; ground learning in intuitive theories of physics and psychology to support and enrich the knowledge that is learned; and harness compositionality and learning-to-learn to rapidly acquire and generalize knowledge to new tasks and situations. We suggest concrete challenges and promising routes toward these goals that can combine the strengths of recent neural network advances with more structured cognitive models. (shrink)

How do teachers learn about what learners already know? How do learners aid teachers by providing them with information about their background knowledge and what they find confusing? We formalize this collaborative reasoning process using a hierarchical Bayesian model of pedagogy. We then evaluate this model in two online behavioral experiments (N = 312 adults). In Experiment 1, we show that teachers select examples that account for learners' background knowledge, and adjust their examples based on learners' feedback. In Experiment 2, (...) we show that learners strategically provide more feedback when teachers' examples deviate from their background knowledge. These findings provide a foundation for extending computational accounts of pedagogy to richer interactive settings. (shrink)

We were encouraged by the broad enthusiasm for building machines that learn and think in more human-like ways. Many commentators saw our set of key ingredients as helpful, but there was disagreement regarding the origin and structure of those ingredients. Our response covers three main dimensions of this disagreement: nature versus nurture, coherent theories versus theory fragments, and symbolic versus sub-symbolic representations. These dimensions align with classic debates in artificial intelligence and cognitive science, although, rather than embracing these debates, we (...) emphasize ways of moving beyond them. Several commentators saw our set of key ingredients as incomplete and offered a wide range of additions. We agree that these additional ingredients are important in the long run and discuss prospects for incorporating them. Finally, we consider some of the ethical questions raised regarding the research program as a whole. (shrink)
