Is Kantian Ethics guilty of utopian thinking? First, potentially good and bad uses of utopian ideals are distinguished, then an apparent path is traced from Rousseau’s unworkable political ideal to Kant’s ethical ideal. Three versions of Kant’s Categorical Imperative are examined briefly for the ways that they may raise the suspicion that they manifest or encourage bad utopian thinking. In each case Kantians have available responses to counter the suspicion, but special attention is directed to the version that (...) says “Act on the maxims of a universally law–giving member of a kingdom of ends.” Interpretations vary, but here primary focus is on one contemporary reconstruction and development of this central idea. Several objections suggest that this idea encourages bad utopian thinking are briefly addressed: that we cannot count on everyone to follow ideal rules, that even conscientious people disagree in their moral judgments, and that theories that allow exceptions to familiar moral rules create a “slippery slope” to moral chaos.

In this open access book, Timothy Aylsworth and Clinton Castro draw on the deep well of Kantian ethics to argue that we have moral duties, both to ourselves and to others, to protect our autonomy from the threat posed by the problematic use of technology. The problematic use of technologies like smartphones threatens our autonomy in a variety of ways, and critics have only begun to appreciate the vast scope of this problem. In the last decade, we have (...) seen a flurry of books making “self-help” arguments about how we could live happier, more fulfilling lives if we were less addicted to our phones. But none of these authors see this issue as one involving a moral duty to protect our autonomy. (shrink)

In this essay, I develop the duty to care. I argue that certain needs do require a moral response. Under the duty to care, moral individuals must act so as to bolster and safeguard the agency of those in need. Substantively, the duty to care features five qualities. It endorses a wide variety of forms of care. It does not demand that caretakers feel certain emotions for their charges. It places limits on the extent of self-sacrifice involved in meeting others’’ (...) needs. It is action oriented. Finally, it is nonpaternalistic. I take a unique approach to develop the duty to care, bringing Kantian ethics and feminist care ethics into conversation with one another in order to highlight the exciting contributions that both have to offer this account. I propose that building on the Kantian duty of beneficence, one can articulate a duty that explains why we are obligated to respond to certain needs found in others. Although the Kantian duty of beneficence provides some resources to use in developing this explanation, I also employ a care ethics perspective to offer an important angle of critique through which one can see both moments when Kant’s account fails (which I consider in a series of four objections) and why care ethics must be incorporated into any worthwhile discussion of meeting needs. Thus the duty to care, while drawing upon the duty of beneficence for its foundation, moves beyond it. Demonstrated through the duty to care’s responsiveness to perceptive objections that care ethicists might raise, the duty to care emerges as a distinctive duty in its own right, one sensitive to the moral concerns of agency, need, and care.

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)

Artificial intelligence and robotics is pervasive in daily life and set to expand to new levels potentially replacing human decision-making and action. Self-driving cars, home and healthcare robots, and autonomous weapons are some examples. A distinction appears to be emerging between potentially benevolent civilian uses of the technology (eg unmanned aerial vehicles delivering medicines), and potentially malevolent military uses (eg lethal autonomous weapons killing human com- batants). Machine-mediated human interaction challenges the philosophical basis of human existence and ethical conduct. Aside (...) from technical challenges of ensuring ethical conduct in artificial intelligence and robotics, there are moral questions about the desirability of replacing human functions and the human mind with such technology. How will artificial intelligence and robotics engage in moral reasoning in order to act ethically? Is there a need for a new set of moral rules? What happens to human interaction when it is mediated by technology? Should such technology be used to end human life? Who bears responsibility for wrongdoing or harmful conduct by artificial intelligence and robotics? -/- Whilst Kant may be familiar to international lawyers for setting restraints on the use of force and rules for perpetual peace, his foundational work on ethics provides an inclusive moral philosophy for assessing ethical conduct of individuals and states and, thus, is relevant to discussions on the use and development of artificial intelligence and robotics. His philosophy is inclusive because it incorporates justifications for morals and legitimate responses to immoral conduct, and applies to all human agents irrespective of whether they are wrongdoers, unlawful combatants, or unjust enemies. Humans are at the centre of rational thinking, action, and norm-creation so that the rationale for restraints on methods and means of warfare, for example, is based on preserving human dignity as well as ensuring conditions for perpetual peace among states. Unlike utilitarian arguments which favour use of autonomous weapons on the basis of cost-benefit reasoning or the potential to save lives, Kantian ethics establish non-consequentialist and deontological rules which are good in themselves to follow and not dependent on expediency or achieving a greater public good. -/- Kantian ethics make two distinct contributions to the debate. First, they provide a human-centric ethical framework whereby human exist- ence and capacity are at the centre of a norm-creating moral philosophy guiding our understanding of moral conduct. Second, the ultimate aim of Kantian ethics is practical philosophy that is relevant and applicable to achieving moral conduct. -/- I will seek to address the moral questions outlined above by exploring how core elements of Kantian ethics relate to use of artificial intelli- gence and robotics in the civilian and military spheres. Section 2 sets out and examines core elements of Kantian ethics: the categorical imperative; autonomy of the will; rational beings and rational thinking capacity; and human dignity and humanity as an end in itself. Sections 3-7 consider how these core elements apply to artificial intelligence and robotics with discussion of fully autonomous and human-machine rule-generating approaches; types of moral reasoning; the difference be- tween ‘human will’ and ‘machine will’; and respecting human dignity.

In this lesson, I review critical responses to Kant that can be understood as having non-Western, Indian roots. One criticism is articulated by the famous contemporary moral philosopher, Thomas Nagel. While Nagel is not a Buddhist, his criticism of Kant’s ethics is Buddhist in essence. The other response is based on an appreciation of the philosophy of Yoga. Yoga and Kantian thought are both versions of a kind of moral philosophy, which we could call Explanatory Dualism. Moreover, Yoga (...) and Kantian moral philosophies attempt to defend Normative Compatibilism, which is a version of Nonnaturalism. Yet, Kant relies upon the idea of Humanity, which is a naturalistic concept, while the Yogi defers to the nonspecisit, abstraction of the Lord to account for moral standing. (shrink)

It seems, at first glance, that a Kantian ethics approach to moral enhancement would tend towards the position that there could be no place for emotional modulation in any understanding of the endeavour, owing to the typically understood view that Kantian ethics does not allow any role for emotion in morality as a whole. It seems then that any account of moral bioenhancement which places emotion at its centre would therefore be rejected. This article argues, however, (...) that this assumption is incorrect. Given later writings by Kant on the role of sympathy, and taking into account other concerns in Kantian ethics, it may in fact be the case that Kantian ethics would allow for an account of moral bioenhancement through emotional modulation, and that in some cases such an intervention might even be considered to be a duty.

In this book, Allen Wood investigates Kant's conception of ethical theory, using it to develop a viable approach to the rights and moral duties of human beings. By remaining closer to Kant's own view of the aims of ethics, Wood's understanding of Kantian ethics differs from the received 'constructivist' interpretation, especially on such matters as the ground and function of ethical principles, the nature of ethical reasoning and autonomy as the ground of ethics. Wood does not (...) hesitate to criticize and modify Kant's conclusions when they seem inconsistent with his basic principles or fail to make the best use of the resources Kantian principles make available. Of special interest are the book's treatment of such topics as freedom of the will, the state's role in securing economic justice, sexual morality, the justification of punishment, and the prohibition on lying.

This article compares two groundings of ethics: the ethical postulates of Immanuel Kant with the existential thinking of S. Kierkegaard. To achieve this goal, first, it proposes highlighting the fundamental ideas of Kantian ethics; then, secondly, highlighting Kierkegaard’s ethical stance; and finally, contrasting both approaches to identify differences and similarities. Conclusively, we can say that the pure Kantian ethical formality of duty for duty’s sake necessarily dispenses with existential and concrete content; it is an ethics (...) that is grounded in itself, that refers to itself, to the rational nature of the human being and its universality. In contrast, Kierkegaardian ethics is a Christian ethics, it is the ethics of love for one’s neighbour and, above all, for God; it is a relational and existential ethics of the single individual.

In this volume Paul Formosa sets out a novel approach to Kantian ethics as an ethics of dignity by focusing on the Formula of Humanity as a normative principle distinct from the Formula of Universal Law. By situating the Kantian conception of dignity within the wider literature on dignity, he develops an important distinction between status dignity, which all rational agents have, and achievement dignity, which all rational agents should aspire to. He then explores constructivist and (...) realist views on the foundation of the dignity of rational agents, before developing a compelling account of who does and does not have status dignity and of what kind of achievement dignity or virtue we, as vulnerable rational agents, can and should strive for. His study will be highly valuable for those interested in Kant's ethical, moral and political philosophies. (shrink)

The emphasis on duly in Kant's ethics is widely held to constitute a defect. Marcia W. Baron develops and assesses the criticism, which she sees as comprising two objections: that duty plays too large a role, leaving no room for the supererogatory, and that Kant places too much value on acting from duty. Clearly written and cogently argued, Kantian Ethics Almost without Apology takes on the most philosophically intriguing objections to Kant's ethics and subjects them to (...) a rigorous yet sympathetic assessment.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Kantian Ethics and Economics: Autonomy, Dignity, and CharacterIvan A. BoldyrevMark D. White. Kantian Ethics and Economics: Autonomy, Dignity, and Character. Stanford, CA: Stanford University Press, 2011. Pp. xi + 270. Cloth, $55.00.This remarkable book provides a new ethical perspective for economics based on Kantian ethics of autonomy and dignity. There are two main messages in it that I find particularly important. First, (...) Mark White derives from Kant the idea of irreducible moral principles that govern the behavior of economic agents independently of welfarist and, more generally, consequentialist concerns. These principles of duty and the “incomparable worth” (21) of human dignity, as well as justice or rights, may not be economically traded off against some other motivations; hence, they simply evade economic reasoning altogether.Second, White endorses a version of libertarian Kantianism that treats people as individuals in essence (“autonomous”) and social in orientation (respecting the rights and the choices of the others). In discussing individualism, White attacks the conventional wisdom of economics and claims that preferences alone do not account for the identity of individuals [End Page 298] in space and time, although their unique characters do. Persons should be given free choice (absent in deterministic rational-choice models) and hence responsibility for their choices that incorporates the social factors in decision-making. However, White never mentions the almost insurmountable difficulties associated with fleshing out the truly individual features of a given person. Although he allows for a person’s identity and character changing over time, he does not recognize that character itself is in many respects a social construction.White criticizes paternalistic economic policies that suggest manipulating choice environments in order to follow the “true” preferences of the individuals. Instead, real consent, as satisfying both relevant preferences and principles (e.g. rights and human dignity), is, in his view, the sole criterion for justifying particular policy measures—not Pareto-efficiency or Kaldor-Hicks compensation. Economists’ obsession with efficiency leading to the misconceived notions such as “efficient level of crime” or “manageable level of terrorism” is also severely criticized.For White, the most popular formalistic version of the categorical imperative is less important than the other two—prohibiting treating other people simply as means and instituting the “Kingdom of Ends.” Formalism is reserved merely for the negative evaluation of actions and providing strict perfect duties that give clear guidance concerning what should not be done. White’s “Kantian-economic” model of decision-making incorporates perfect duties as constraints, and imperfect (positive) duties as preferences. He also stresses that for Kant, duties derived from the imperative depend on empirical knowledge, the context of decision-making, and judgment as a unique personal interpretation of the moral law. He further emphasizes the intersubjective role of Kantian morality: moral law should be universalizable to all rational persons (the “Kingdom of Ends” formula of the imperative), whereas rationality means not just following the patterns of behavior developed in the preference-oriented choice model, but rather acting on one’s beliefs and desires or choosing not to follow them, thus exhibiting genuine autonomy.The new and important contribution to the discussion is an explicit treatment of will as an inner faculty that, together with judgment, constitutes a person’s character or “self,” and helps to overcome the mere inclination to follow duty. Will is the missing link between decision and action and should be “well-trained” for bringing about true morality.The book is clearly written, and the author has upheld the interdisciplinary appeal of the topic, demonstrating an outstanding knowledge of the vast literature on ethics (both Kantian and not) and economics. White’s emphasis on the irreducibility of moral principles is absolutely relevant for current economic and political debates. However, some reservations are in order.There is an ambiguity concerning the status of his analysis. If in its positive aspect White’s recommendations for economists is to accept the Kantian vision of morality, then almost no arguments are given for this, and his modifications of the standard choice model are introduced in an ad hoc manner, just to reconcile it with the Kantian framework. Are an individual’s decisions to act on principles and to overcome mere inclinations really... (shrink)

This volume presents a selection of Robert Stern's work on the theme of Kantian ethics. It begins by focusing on the relation between Kant's account of obligation and his view of autonomy, arguing that this leaves room for Kant to be a realist about value. Stern then considers where this places Kant in relation to the question of moral scepticism, and in relation to the principle of 'ought implies can', and examines this principle in its own right. The (...) papers then move beyond Kant himself to his wider influence and to critics of his work, and the volume concludes with a consideration of a broadly Kantian critique of divine command ethics offered by Stephen Darwall. General themes considered in this volume include value, perfectionism, agency, autonomy, moral motivation, moral scepticism, and obligation, as well as the historical place of Kant's ethics and its influence on thinkers up to the present day.

The author examines whether Kantian ethics would condone the use of pharmaceutical drugs to enhance one’s moods and cognitive abilities. If key assumptions concerning safety and efficacy, non-addictiveness, non-coercion, and accessibility are not met, Kantian ethics would consider mood and cognitive enhancement to be impermissible. But what if these assumptions are granted? The arguments for the permissibility of neuroenhancement are stronger than those against it. After giving a general account of Kantian ethical principles, the author (...) argues that, when these assumptions are granted, Kantian ethics no longer justifies the prohibition of neuroenhancement, and responds to two objections.

This study argues for three main theses: (1) Immanuel Kant’s ethics is a social ethics; (2) the basic premises of his social ethics point to a socialist ethics; and (3) this socialist ethics constitutes a suitable platform for criticizing and improving Karl Marx’s view of morality. -/- Some crucial aspects of Kant’s social ethics are that we must promote the “realm of ends” as a moral society of co-legislators who assist each other in the (...) pursuit of their individual ends, which requires in turn that we seek the realization of the republican state and peace between the nations. Thus, hope for progress, as supported by the enthusiasm engendered among the spectators of the French Revolution, becomes pivotal to Kant’s ethics as well as other moral feelings such as moral indignation and solidarity with the victims of oppression. -/- Kant views the moral society in the final instance as an “inner” unification of good wills. In a decisive elaboration of Kant, the neo-Kantian Hermann Cohen argues that all our social institutions, and notably economic enterprises, must instantiate the “realm of ends,” leading him to support cooperative socialism in Wilhelmine Germany. In his own words, Kant “is the true and real originator of German socialism” (1896). -/- There are important evaluative similarities between Kantian socialist ethics and Marx, such as a condemnation of capitalism as a system of servitude and an understanding of the ideal society as a cooperative society, but only Marx contends that the ideal society does not set a moral task and that there is a dialectic operative in human history that inevitably leads to communist society. This dogmatic Hegelian understanding of history must be replaced by Kantian regulative understanding of progress in support of revolutionary praxis as moral praxis. -/- We need a “Kantianization” of Marx, as Cohen and other neo-Kantian socialists also proclaimed in the three decades leading up to World War I. This study concludes with “A Historical Note on Kantian Ethical Socialism,” addressing, among others, Cohen, Karl Vorländer, Eduard Bernstein, and Kurt Eisner and the Munich Revolution of 1918. Their voices were largely silenced by the rise of fascism, and this study hopes to show that their voices still need to be heard. -/- Awarded the 1985 Johnsonian Prize in Philosophy. (shrink)

Heidegger’s Being and Time has been accused of espousing empty decisionism and relativism. I argue, first, that in fact Being and Time’s stress on the situated character of human judgment is supplemented by a very Kantian account of being human that defi nes appropriate behavior towards all entities possessing a certain character. Its analysis of conscience and guilt attempts to uncover the existential basis for the distinction Kant draws between the phenomenal and the noumenal aspects of the self. Building (...) on this analysis, I claim, Being and Time reaffirms the second version of Kant’s categorical imperative, which states that humanity should never be treated merely as a means, but always also as an end in itself. In the second part of the paper, however, I argue that this proximity to Kant is part of the problem with Being and Time, that some of this work’s shortcomings and dangers in relation to ethics rest precisely in its very Kantian view of what makes an entity worthy of moral concern, and what is owed to others in virtue of their being such worthy entities. As a consequence of this view, not only are all nonhuman animals excluded from moral concern, but, strangely, the intrinsic value of human well-being is itself threatened. (shrink)

Ethicists who have been influenced by Kant's critical moral philosophy are called ‘Kantian’. The term can also be extended to ethicists who grappled with and rejected Kant or the Kantian spirit. This chapter first discusses the core of Kant's ethics, those important theorems that provide a criterion for determining the extent to which a given ethics is indeed ‘Kantian’. It then considers the views of several Kantians, including Friedrich Schiller, Karl Leonhard Reinhold, Johann Gottlieb Fichte, (...) Friedrich Wilhelm Joseph Schelling, Georg Wilhelm Friedrich Hegel, Arthur Schopenhauer, and Friedrich Nietzsche. (shrink)

Kant's deontological ethical theory is explained in terms that introductory students can understand.

Kantian Ethics aims to develop a defensible theory of ethics on the basis of Kantian principles. Its primary focus is Kantian ethics, not Kant scholarship or interpretation. The book fulfills a promise of Wood’s earlier book, Kant’s Ethical Thought , by developing a Kantian conception of virtue and theory of moral duties in greater detail, and it goes beyond Wood’s previous work on Kant’s ethics in offering extended treatments of substantive moral issues, (...) such as social justice, sexual morality, punishment, lying, consequentialism, personhood, and the status of non-rational animals.Acknowledging that his reading of Kant is now even further from traditional interpretations than it previously was, Wood contends that it is nevertheless “closer to the truth” . He aims to correct what he takes to be some serious misinterpretations of Kant’s views and, in setting the record straight, to provide for us “a better understanding of Kant’s own thoughts” . Some familiar points that Wood rejects are the ideas that Kant’s moral psychology involves a sharp dualism between nature and freedom, and that he was unconcerned with the empirical nature of human beings and human history, regarding such issues as entirely irrelevant to morality.

This book introduces the moral philosophy of Immanuel Kant—in particular, the concepts of autonomy, dignity, and character—to economic theory, explaining the importance of integrating these two streams of intellectual thought. Mainstream economics is rooted in classical utilitarianism, recommending that decision makers choose the options that are expected to generate the largest net benefits. For individuals, the standard economic model fails to incorporate the role of principles in decision-making, and also denies the possibility of true choice, which can be independent of (...) preferences and principles altogether. For policymakers, standard decision-making frameworks recommend tradeoffs that are beneficial in terms of material goods or wealth, but may be morally questionable from a more person-centered perspective. Integrating Kantian ethics affects economics in three important ways. This integration allows for a more complete understanding of human choice, incorporating not just preferences and constraints, but also principles and strength of will or character. It demonstrates the broader impact of welfare economics, which generates policies that affect not only persons' well-being, but also their dignity and autonomy. Finally, it reconciles the traditional, individualist stance in economic models of choice with the social responsibility emphasized by many systems of philosophical ethics and heterodox schools of economics.

This essay questions whether recent attempts to reconcile Kantian ethics and intimate attachments can be successful. Defenders have argued that Kantian commitments would leave enough room to pursue the sorts of intimate attachments that provide so much of the meaning and structures of most lives. However, close attention to the letter and spirit of Kant's ethics suggests that imperfect duties would demand far more of conscientious Kantians than defenders have acknowledged. The duties to prevent injustice and (...) alleviate suffering should occupy enough of a good Kantian's life in most cases to strain more intimate commitments. (shrink)

The broad range of the managements of the natural resources in Tanzania has resulted into the creation of complex organizations and systems which has led to the exploitation of the workers depending on these resources for livelihood. These are various groups of actors such as insurgents’ groups, minority groups, and corrupt democratically elected leaders. Obviously, these leads to internal mistrust and commotion within a state rendered in calmness and contrary to peaceful coexistence. As a researcher the bottom line of these (...) constrains needs holistic education and realization to combat the eminent crisis at hand. Each person has a role to play for the peaceful living in a society with great goals and opportunities. The dignity and integrity of each person is a very important and at stake. My research analysis indicates how Kantian ethics will tackle the above mentioned constrains for the peaceful coexistence in the society. For Kant, every human being has a right and obligation for every moral action. In any democratic society where laws and statutes are adhered to the issues of natural resources must be accounted for with the aim of common good. Using Immanuel Kant’s dictum on categorical imperative, these transformations in the management of the natural resources in Tanzania can be effectively be achieved. (shrink)

We articulate and defend the most central claims of contemporary Kantian moral theory. We also explain some of the most important internal disagreements in the field, contrasting two approaches to Kantian ethics: Kantian Constructivism and Kantian Realism.

The ethics of care has always had an opposing theoretical model in Kant’s ethics. While Kant’s ethics seems to draw an image of the moral agent as independent, autonomous, and rational, the ethics of care insists on a characterisation of the person as vulnerable, interdependent, and relational, for whom the affective dimension plays a crucial role. On the contrary, my thesis is that the two theoretical proposals are not incompatible. I will provide three arguments for this (...) thesis. First, I will analyse the possibility of interpreting the Kantian agent as a vulnerable, emotional and, at the same time, autonomous subject. Second, I will show how, for Kant, relations have normatively relevant weight within the agent’s deliberation. Finally, I intend to argue that Kant does not lose the particular in favour of techniques of abstraction and generalisation, but keeps it within the agent’s maxim and preserves it in the process of moral deliberation.

The ethics of care, adopted in much of the nursing literature, is usually framed in opposition to the Kantian ethics of principle. Irrespective of whether the ethics of care is grounded in gender, as with Gilligan and Noddings, or inscribed on Heidegger's ontology, as with Benner, Kant remains the philosophical adversary, honouring reason rather than emotion, universality rather than context, and individual autonomy rather than interdependence. During the past decade, however, a great deal of Kantian (...) scholarship – including feminist scholarship – has rendered this series of oppositions questionable, challenging the view that an ethics of care and Kant's moral law are irreconcilable. This paper therefore re‐examines Kant's writings, drawing on recent scholarship, and argues both that they provide the care ethicists with everything they require, and that they offer something beyond an ethics of care, something that repairs the deficits in philosophies of caring. It concludes by suggesting that a Kantian ethics of care has significant implications for the construction of nursing knowledge. (shrink)

Kantian Ethics: Value, Agency, and Obligation. By Robert Stern.

Historically, studies in Kant’s ethics have tended to prioritize his formal work in moral philosophy. This has begun to change with a welcome new emphasis on his later practical works, but commentators still tend to approach this material in the shadow of the Groundwork with the same limited set of concerns and problems in mind. Practical Kantian Ethics reverses the usual order of interpretation, beginning with his applied moral philosophy, without preconceptions about his view, and using this (...) later work to offer a radically new account. -/- The “inner freedom” model it proposes connects and explains diverse threads in Kant’s moral theory informing obscure aspects of the Groundwork but also, and just as importantly, offering a radically different and comprehensive vision of Kantian moral life. This new account transcends the narrow rational asceticism often associated with Kant’s view, embedding morality in our humanity, recognizing the vital role of emotion in moral life, and prioritizing framing moral commitments and questions of character over obedience to formal rules. In doing so, it makes community and collective and individual judgment essential in giving content to ideals of practical respect, creating important space for moral disagreement and growth. The net result is a nuanced account focused on the integration of diverse norms and the lived experience of morality, capable of guiding ordinary moral judgement and informing deliberation in hard cases where different grounds of obligation conflict. -/- .

Legal systems divide the world into persons and property, treating animals as property. Some animal rights advocates have proposed treating animals as persons. Another option is to introduce a third normative category. This raises questions about how normative categories are established. In this article I argue that Kant established normative categories by determining what the presuppositions of rational practice are. According to Kant, rational choice presupposes that rational beings are ends in themselves and the rational use of the earth’s resources (...) presupposes that human beings have rights. I argue that rational choice also presupposes that any being for whom things can be good or bad must be regarded as an end in itself, and that the use of the world’s resources presupposes that any being who depends on those resources has rights. Although the other animals do not engage in rational practice, our own rational practice requires us to give them standing. (shrink)

Perfect ethical duties have usually puzzled commentators on Kant's ethics because they do not fit neatly within his taxonomy of duties. Ethical duties require the adoption of maxims of ends: the happiness of others and one's own perfection are Kant's two main categories. These duties, he claims, are of wide obligation because they do not specify what in particular one ought to do, when, and how much. They leave ‘a latitude for free choice’ as he puts it. Perfect duties, (...) however, such as the duties of respect, to avoid suicide, lying, and servility, do not appear to require the adoption of ends but only the performance or omission of specific types of actions. The puzzle is how these duties can be ethical, and therefore wide. Faced with this difficulty, Mary Gregor denies that perfect ethical duties are wide. She claims that they are an ‘anomaly’ and that they do not belong to ethics proper but to moral philosophy in general. She argues that these duties are derived from the categorical imperative, instead of, as Kant himself appears to have thought, the first principle of virtue. Taking a very different approach, Onora O'Neill finds the perfect/imperfect distinction of little importance and suggests doing without it altogether. Most other interpreters also assume that ‘wide’ is opposed to ‘perfect’ so that a wide perfect duty is a conceptual impossibility. (shrink)

Kantian ethics is both very much alive and very much under attack in recent moral philosophy, and so I propose to review some of the discussion, though I must say in advance that my review will have to be incomplete and oversimplified in various ways.

No understanding of morality has more zealous or influential defenders among academic philosophers than Kant’s. Yet as Michael Rosen demonstrates in The Shadow of God, there is a sense in which Kant’s critics take his conception of freedom more seriously nowadays than his defenders. As a result, contemporary versions of “Kantian ethics” often end up challenging what Rosen calls “the ethics of Kant,” not just the claims of rival moral theories. Rosen supports this surprising conclusion with some (...) powerful arguments, showing that we cannot make sense of Kantian moral philosophy or its extraordinary impact on modern philosophy while detaching it from Kant’s conception of transcendental freedom. But Rosen overstates the continuity between Kant and the Idealist philosophers that he inspired. Thinkers like Schiller, Schelling, and Hegel took Kant’s concept of transcendental freedom far more seriously than defenders of Kantian ethics do today. But precisely because they did so, they felt compelled to address a whole new set of problems, which could be solved only by radically transforming the conception of freedom that they received from Kant.

Few challenges facing Kantian ethics are more famous and formidable than the so-called "case of the inquiring murderer." It appears in some form today in most introductory ethics texts, but it is not a new objection. Even Kant himself was compelled to respond to it, though by most accounts his response was embarrassingly unpersuasive. A more satisfactory reply can be offered to this old objection, however. It will be shown here that Kantian ethics permits lying (...) to inquirers asking wrong questions, and that, therefore, it can be right to lie to a murderer inquiring whether his intended victim is hiding in your house. We begin by reviewing a now popular and plausible-sounding defense of the right to lie. Finding it unsuccessful, we turn next to scrutinize the type of question asked. The case of the inquiring murderer cannot be presented without supposing that the murderer's inquiry is unevadable. As we shall then see, in Kantian ethics it is usually wrong to ask such questions.

Wild animals probably have net negative lives. Christine Korsgaard rejects the view that we might engineer paradise by redesigning nature and animals so that they have the best possible existences. She believes the genetic changes required would not be identity-preserving, thereby causing animals to cease to exist. I argue, first, that paradise engineering is permissible. Many harms are caused by non-sentient natural entities and processes. Moreover, sentient animals can survive modifications compatible with their psychological persistence over time. Second, we are (...) required to re-engineer nature in order to satisfy animals' right to the resources necessary for a reasonable life. (shrink)

Heidegger’s Being and Time has been accused of espousing empty decisionism and relativism.

In the second part of the paper, however, I argue that this proximity to Kant is part of the problem with Being and Time, that some of this work’s shortcomings and dangers in relation to ethics rest precisely in its very Kantian view of what makes an entity worthy of moral concern, and what is owed to others in virtue of their being such worthy entities. As a consequence of this view, not only are all nonhuman animals excluded from moral concern, but, strangely, the intrinsic value of human well-being is itself threatened. (shrink)

Are the houyhnhnms, the rational horses Gulliver meets in the fourth chapter of Jonathan Swift’s Gulliver’s Travels (1726), meant as role models for man? I think there are reasons to doubt this view. To illustrate this claim, I’ll compare Swift’s portrayal of the houyhnhnms with Immanuel Kant’s Groundwork to the Metaphysics of Morals (1785). There, Kant explicates that man is no ‘purely rational being’ but a ‘sensual rational being’. We’ll see that this characterization has tremendous consequences for the justification of (...) Kant’s moral principle. Similarly, Swift designates man as an animal rationis capax, i.e. an animal which is only capable of reasoning, but not wholly governed by it. Violations of moral norms are hence very likely to occur. Concluding, I shall argue that the houyhnhnms are no role-models because their morality runs counter to human nature. Instead, they serve to show that man adheres to an illusion. (shrink)
