Ethical evaluation of deep brain stimulation as a treatment for Parkinson’s disease is complicated by results that can be described as involving changes in the patient’s identity. The risk of becoming another person following surgery is alarming for patients, caregivers and clinicians alike. It is one of the most urgent conceptual and ethical problems facing deep brain stimulation in Parkinson’s disease at this time. In our paper we take issue with this problem on two accounts. First, we elucidate what is (...) meant by “becoming another person” from a conceptual point of view. After critically discussing two broad approaches we concentrate on the notion of “individual identity” which centers on the idea of “core attitudes”. Subsequently we discuss several approaches to determine what distinguishes core attitudes from those that are more peripheral. We argue for a “foundational-function model” highlighting the importance of specific dependency relations between these attitudes. Our second aim is to comment on the possibility to empirically measure changes in individual identity and argue that many of the instruments now commonly used in selecting and monitoring DBS-patients are inappropriate for this purpose. Future research in this area is advised combining a conceptual and an empirical approach as a basis of sound ethical appraisal. (shrink)

Jens Timmermann provides a detailed philosophical, developmental and historical analysis of Immanuel Kant's 1797 essay 'On a Supposed Right to Lie from Love of Humanity', in which Kant argues that it is criminally wrong to lie to protect a friend from being murdered.

Even the most sympathetic readers of Kant's moral philosophy usually disagree with him about some aspect of his theory, or some particular moral judgement. His unqualified condemnation of lying in the essay ‘On a supposed right to lie from philanthropy’ is a classical case in question, as is his strong endorsement of retributive justice and the death penalty. A third prominent source of discontent are Kant's repeated verdicts on the moral status of non-human animals, or rather the lack thereof. For, (...) despite the fact that his practical recommendations in this field are sensible and even progressive, he repeatedly insists that there are no direct duties to animals, that the well-being of animals is morally indifferent, in particular that we ought to treat animals decently solely for the sake of humanity. As a result, the foundations of his advice seem morally inadequate, even offensive. (shrink)

In 1993, Richard Hare argued that, contrary to received opinion, Kant could have been a utilitarian. In this article, I argue that Hare was wrong. Kant's theory would not have been utilitarian or consequentialist even if his practical recommendations coincided with utilitarian commands: Kant's theory of value is essentially anti-utilitarian; there is no place for rational contradiction as the source of moral imperatives in utilitarianism; Kant would reject the move to separate levels of moral thinking: first-order moral judgement makes use (...) of the principle of morality; and, relatedly, he would resist the common utilitarian distinction between actions and their motives because any correct description of an action must refer to motivation. The article concludes with the thought that any consequentialist theory based on pre-given ends (teleology) lacks the philosophical resources to distinguish between willing something as a means and as an end, leaving means only, and destroying transparency.

This paper explores the possibility of moral conflict in Kant’s ethics. An analysis of the only explicit discussion of the topic in his published writings confirms that there is no room for genuine moral dilemmas. Conflict is limited to nonconclusive ‘grounds’ of obligation. They arise only in the sphere of ethical duty and, though defeasible, ought to be construed as the result of valid arguments an agent correctly judges to apply in the situation at hand. While it is difficult to (...) determine in theory what makes some of them stronger than others, these ‘grounds’ can account for practical residue in conflict cases and for a plausible form of agent regret. The principle that ‘ought implies can’ survives intact. (shrink)

The Groundwork of the Metaphysics of Morals is Kant's central contribution to moral philosophy, and has inspired controversy ever since it was first published in 1785. Kant champions the insights of 'common human understanding' against what he sees as the dangerous perversions of ethical theory. Morality is revealed to be a matter of human autonomy: Kant locates the source of the 'categorical imperative' within each and every human will. However, he also portrays everyday morality in a way that many readers (...) find difficult to accept. The Groundwork is a short book, but its argument is dense, intricate and at times treacherous. This commentary explains Kant's arguments paragraph by paragraph, and also contains an introduction, a synopsis of the argument, six short interpretative essays on key topics of the Groundwork, and a glossary of key terms. It will be an indispensable tool for anyone wishing to study the Groundwork in detail. (shrink)

Is Kant’s ethical theory too demanding? Do its commands ask too much of us, either by calling for self-sacrifice on particular occasions, or by pervading our lives to the extent that there is no room for permissible action? In this article, I argue that Kant’s ethics is very demanding, but not excessively so. The notion of ‘latitude’ does not help. But we need to bear in mind that moral laws are self-imposed and cannot be externally enforced; that ‘right action’ is (...) not a category of Kantian ethics – there is a more and a less, and lack of perfection does not entail vice; and that only practice makes perfect, i.e. how much virtue can realistically be expected can vary from agent to agent. The principle that ‘ought’ is limited by ‘can’ is firmly entrenched in Kant’s ethical thought. (shrink)

There seems to be a strong sentiment in pre-philosophical moral thought that actions can be morally valuable without at the same time being morally required. Yet Kant, who takes great pride in developing an ethical system firmly grounded in common moral thought, makes no provision for any such extraordinary acts of virtue. Rather, he supports a classification of actions as either obligatory, permissible or prohibited, which in the eyes of his critics makes it totally inadequate to the facts of morality. (...) The related idea of uncommonly grand and noble deeds is frequently dismissed by Kant as high-.own emotional nonsense. Such considerations give rise to the fear that actions intuitively classed as morally commendable but not required must be re-classified as commands of duty by Kant, making his ethical theory as unbearably demanding as direct utilitarianism. The paper divides into three sections: (1) an examination of the nature of moral goodness from a meta-ethical angle that introduces some passages from Kant's writings presenting strong theoretical evidence against the case for supererogatory action; (2) a critique of Thomas Hill's suggestion that within the category of wide duty we can accommodate some of the main features of actions classified as supererogatory in other ethical systems; concluding that, contra Hill, there are no actions of wide duty that can be so characterized in any significant sense; and (3) a final discussion of the problem of how demanding the requirements of Kantian ethical theory really are.

Published in 1785, Immanuel Kant's Groundwork of the Metaphysics of Morals ranks alongside Plato's Republic and Aristotle's Nicomachean Ethics as one of the most profound and influential works in moral philosophy ever written. In Kant's own words, its aim is to identify and corroborate the supreme principle of morality, the categorical imperative. He argues that human beings are ends in themselves, never to be used by anyone merely as a means, and that universal and unconditional obligations must be understood as (...) an expression of the human capacity for autonomy and self-governance. As such, they are laws of freedom. This volume contains Mary Gregor's acclaimed translation of the text into English, revised by Jens Timmermann, and an accessible, updated introduction by Christine Korsgaard. (shrink)

Das Buch behandelt Kants Versuch, innerhalb seiner Ethik Sittengesetz, Naturgesetz und Freiheit im moralischen Handeln in Einklang zu bringen. Im ersten Teil stehen die Begriffe der Freiheit und des Willens bei Kant im Mittelpunkt. Der zweite Teil untersucht detailliert die Kernpunkte der kantischen Ethik: den (letztlich gescheiterten) Versuch, Freiheit und Naturkausalit t auszus hnen, und die Theorie des Handelns nach Moralgesetzen, deren Wahl den freien Willen als eigentliches Moment ausmacht. Am Ende steht die Einsicht in ein hoch entwickeltes, differenziertes gedankliches (...) System, das unserer Alltagsauffassung von moralischer Verantwortung erstaunlich nahe kommt. (shrink)

Kant’s concept of conscience has been largely neglected by scholars and contemporary moral philosophers alike, as has his concept of “indirect” duty. Admittedly, neither of them is foundational within his ethical theory, but a correct account of both in their own right and in combination can shed some new light on Kant’s moral philosophy as a whole. In this paper, I first examine a key passage in which Kant systematically discusses the role of conscience, then give a systematic account of (...) “indirect” duties and the function of hypothetical imperatives in the course of their generation. I then turn to the possibility of moral error and the part “indirect” duty can play in its prevention. In conclusion, I try to show how clarifying the concept of “indirect” duty can help us to shed light on the nature of Kantian ethics as a whole. (shrink)

What happens when human beings fail to do as reason bids? This book is an attempt to address this age-old question within Kant’s mature practical philosophy, i.e. the practical philosophy that emerged with the watershed discovery of autonomy in the mid-1780s. As always, Kant is good for a surprise. There is, it is argued, not one answer but two: he advocates Socratic intellectualism in the realm of prudence whilst defending an anti-intellectualist or volitional account of immoral action. This ‘hybrid’ theory (...) of practical failure is more than a philosophical curiosity. There are ramifications for Kant’s theory of practical reason as a whole. In particular, the hybrid account emphasizes the divide between pure and empirical practical rationality to the extent that the latter, while containing practically relevant propositions, no longer counts as a branch of practical reason at all. Hypothetical and categorical imperatives exemplify two entirely distinct kinds of normativity. In fact, the dichotomy between pure and empirical determining grounds of the will goes hand in hand with many other dualisms and dichotomies that, whether we like them or not, continue to define Kant’s mature ethical thought. (shrink)

The present article is an attempt to clarify the Kantian conception of duties to the self and to defend them against common objections. Kant’s thesis that all duty rests on duties to the self is shown to follow from the autonomy of the human will; and the allegation that they are impossible because the agent could always release himself from such a duty turns out to be question-begging. There is no attempt to prove that there are such duties, but they (...) are revealed to be an indispensable part of morality. Traditional attributes of moral commands, such as ‘categoricity’ or ‘overridingness’ make no sense in a one-sidedly other-regarding or social conception of morality. (shrink)

Pauline Kleingeld’s “Contradiction and Kant’s Formula of Universal Law”, published in this journal in 2017, presents a powerful challenge to what has become the standard reconstruction of the categorical imperative. In this response to Kleingeld, I argue that she is right to emphasise the ‘simultaneity requirement’ - that we must be able to will a proposed maxim and ‘simulataneously’, ‘also’ or ‘at the same time’ the maxim in its universalised form - but I deny that this removes the categorical imperative (...) test from the world of universalisation because the agent must be understood as part of that world. There are two distinct types of conflict: a contradiction that results from non-universalisability and Kleingeld’s ‘volitional’ conflict, located within the will of the immoral agent. The standard ‘practical’ reconstruction of the categorical imperative remains largely intact. (shrink)

Building on the results of the Groundwork and the Critique of Practical Reason, Kant finally published his system of moral philosophy in two volumes in 1797. By then, he had been planning to write a Metaphysics of Morals for three decades; but only the title remained unchanged while the basic principles of his theoretical and practical philosophy changed dramatically. While for many years academic moral philosophy focused mainly on Kant’s earlier ethical treatises, there has recently been much interest in this (...) later and perhaps more mature work on moral philosophy, particularly the ethical part of the Metaphysics of Morals, the “Metaphysical Principles of the Doctrine of Virtue” or “Tugendlehre”. The present volume responds to these demands. Following a series of research workshops, 18 scholars from Germany, Italy, Britain and the United States provide a seamless commentary on the “Doctrine of Virtue”, discussing topics such as suicide, truthfulness, moral perfection, beneficence, gratitude, sympathy, respect and friendship as well as Kant’s moral psychology, philosophy of action and theory of moral education. This book will be an invaluable resource for moral philosophers and Kant scholars alike. (shrink)

The Critique of Practical Reason is the second of Kant's three Critiques, and his second work in moral theory after the Groundwork of the Metaphysics of Morals. Its systematic account of the authority of moral principles grounded in human autonomy unfolds Kant's considered views on morality and provides the keystone to his philosophical system. The essays in this volume shed light on the principal arguments of the second Critique and explore their relation to Kant's critical philosophy as a whole. They (...) examine the genesis of the Critique, Kant's approach to the authority of the moral law given as a 'fact of reason', the metaphysics of free agency, the account of respect for morality as the moral motive, and questions raised by the 'primacy of practical reason' and the idea of the 'postulates'. Engaging and critical, this volume will be invaluable to advanced students and scholars of Kant and to moral theorists alike. (shrink)

Section I of Kant's Groundwork of the Metaphysics of Morals is meant to lead us from our everyday conception of morality to the supreme principle of all moral action, officially christened the ‘categorical imperative’ some twenty Academy pages further into the treatise. It is quite striking that in this first section Kant dispenses with the notorious technical language that pervades not just other parts of the Groundwork but also most of the remaining philosophical writings of the critical period. The mere (...) fact that Groundwork I is comparatively accessible does not, of course, make it straightforward or uncontroversial. Kant's readers are faced with, amongst other things, four unconvincing paragraphs on the natural purpose of practical reason (G IV 394–6), a crucial change of topic from good volition to acting from duty (G IV 397), an unstated ‘first proposition’ about moral value that has baffled generations of interpreters (presumably G IV 397–9), and a contentious shift from an allegedly unproblematic principle of practical universalizability to a substantive moral command (G IV 402).

In his Groundwork of the Metaphysics of Morals, Immanuel Kant portrays the supreme moral principle as an unconditional imperative that applies to all of us because we freely choose to impose upon ourselves a law of pure practical reason. Morality is revealed to be a matter of autonomy. Today, this approach to ethical theory is as perplexing, controversial and inspiring as it was in 1785, when the Groundwork was first published. The essays in this volume, by international Kant scholars and (...) moral philosophers, discuss Kant's philosophical development and his rejection of earlier moral theories, the role of happiness and inclination in the Groundwork, Kant's moral metaphysics and theory of value, and his attempt to justify the categorical imperative as a principle of freedom.

In this paper, I explore two closely related ethical principles, ‘Ought implies Can’ and the Kantian ‘Du kannst, denn du sollst’ . The former principle is mainly used to diffuse moral dilemmas and other problem cases. Possibility is a necessary condition of obligation. Recent criticism notwithstanding, the principle is shown to be defensible and useful in the case of genuine, action-guiding oughts. The latter principle makes use of the former, but it in addition presupposes the validity of a moral command (...) and on that basis concludes that the agent must be able to act accordingly. ‘Du kannst, denn du sollst’ has its roots in Kantian ethics: the firm consciousness of moral necessity serves as the ratio cognoscendi of human freedom. The principle is mainly directed against metaphysical scepticism turning on the validity of natural determinism. It is doubtful whether many non-Kantians would be willing to support it in its original metaphysical incarnation. (shrink)

The way we use terminology matters. There are words, ordinary and philosophical, that we should do without because they are ill-defined, ambiguous or confused. If we use them we will at best be saying little. At worst, they will make us ask the wrong questions and leave the right ones unasked. In this paper, I argue that ‘deontology’ is such a word. It is defined negatively as non-teleological or non-consequentialist, and therefore does not designate a distinct class of moral theories, (...) let alone a single one. Moreover, the question whether Kantian ethics is ‘deontological’ is likely to obscure what is distinctive and interesting about it. The word ‘deontology’ should be banished from the classroom. It may be best to abandon it altogether. (shrink)

Published in 1785, the Groundwork of the Metaphysics of Morals is one of the most powerful texts in the history of ethical thought. In this book, Immanuel Kant formulates and justifies a supreme principle of morality that issues universal and unconditional moral commands. These commands receive their normative force from the fact that rational agents autonomously impose the moral law upon themselves. As such, they are laws of freedom. This volume contains the first facing-page German-English edition of Kant's Groundwork. It (...) presents an authentic edition of the German text and a carefully revised version of Mary Gregor's acclaimed English translation, as well as editorial notes and a full bilingual index. It will be the edition of choice for any student or scholar who is not content with reading this central contribution to modern moral philosophy through the veil of English translation. (shrink)

What is the proper task of Kantian ethical theory? This paper seeks to answer this question with reference to Kant's reply to Christian Garve in Section I of his 1793 essay on Theory and Practice . Kant reasserts the distinctness and natural authority of our consciousness of the moral law. Every mature human being is a moral professional—even philosophers like Garve, if only they forget about their ill-conceived ethical systems and listen to the voice of pure practical reason. Normative theory, (...) Kant argues, cannot be refuted with reference to alleged experience. It is the proper task of the moral philosopher to emphasize this fact. The paper also discusses Kant's attempts to clarify his moral psychology, philosophy of value and conception of the highest good in the course of replying to Garve's challenge. Key Words: Christian Garve • ethical theory and practice • Immanuel Kant • moral psychology • theory of value. (shrink)

The ‘unity of reason’ is mentioned at several points in Kant's writings, but it is never systematically discussed or explained in any detail. Occasionally, this ‘unity’ seems something that we can take for granted. At other times, it appears to be a thesis that has just been implicitly established. However, for the most part it is presented as an extremely ambitious, all-encompassing research project that Kant feels he has to postpone until some indefinite time in the future. This chapter tries (...) to disentangle these different ‘unities’ of reason, arguing that Kant was primarily concerned with the unity of the final philosophical system that reason as a unitary faculty seeks to produce, whereas the unity of reason in the sense of a unitary faculty of reason is taken for granted. The chapter focuses on some philosophically important features of Kant's critical theory of reason, reasoning and reasons in the two spheres. (shrink)
