This paper demonstrates something that Kant notoriously claimed to be possible, but which Kant scholars today widely believe to be impossible: unification of all three formulations of the Categorical Imperative. Part 1 of this paper tells a broad-brush story of how I understand Kant’s theory of practical reason and morality, showing how the three formulations of the Categorical Imperative appear to be unified. Part 2 then provides clear textual support for each premise in the argument for my interpretation.

This paper investigates the moral permissibility of torture. After briefly considering some empirical evidence, it discusses the conflict between deontological and consequentialist approaches to torture. It is argued that, even if we are to take rights seriously, torture should at least be allowed if some conditions are satisfied. Finally, the paper discusses what those conditions should be and what sorts of torture are morally permissible.

A central theme of the volume is whether impartiality and partiality are really opposed dimensions or if they can be harmoniously reconciled in one picture of ...

In this article I try to elucidate the concept of human dignity by taking a closer look at the features of a paradigmatic torture situation. After identifying the salient aspects of torture, I discuss various accounts for the moral wrongness of such acts and argue that what makes torture a violation of human dignity is the perverted moral relationship between torturer and victim. This idea is subsequently being substantiated and defended against important objections. In the final part of the chapter (...) I give a (qualified) defense of the methodology employed in the previous sections. (shrink)

Winner of the 1975 National Book Award, this brilliant and widely acclaimed book is a powerful philosophical challenge to the most widely held political and social positions of our age--liberal, socialist, and conservative.

That the successful development of fully autonomous artificial moral agents (AMAs) is imminent is becoming the received view within artificial intelligence research and robotics. The discipline of Machines Ethics, whose mandate is to create such ethical robots, is consequently gaining momentum. Although it is often asked whether a given moral framework can be implemented into machines, it is never asked whether it should be. This paper articulates a pressing challenge for Machine Ethics: To identify an ethical framework that is both (...) implementable into machines and whose tenets permit the creation of such AMAs in the first place. Without consistency between ethics and engineering, the resulting AMAs would not be genuine ethical robots, and hence the discipline of Machine Ethics would be a failure in this regard. Here this challenge is articulated through a critical analysis of the development of Kantian AMAs, as one of the leading contenders for being the ethic that can be implemented into machines. In the end, however, the development of Kantian artificial moral machines is found to be anti-Kantian. The upshot of all this is that machine ethicists need to look elsewhere for an ethic to implement into their machines. (shrink)

The humanity formulation of Kant's Categorical Imperative demands that we treat humanity as an end in itself. Because this principle resonates with currently influential ideals of human rights and dignity, contemporary readers often find it compelling, even if the rest of Kant's moral philosophy leaves them cold. Moreover, some prominent specialists in Kant's ethics have recently turned to the humanity formulation as the most theoretically central and promising principle of Kant's ethics. Nevertheless, it has received less attention than many other (...) aspects of Kant's ethics. Richard Dean offers the most sustained and systematic examination of the humanity formulation to date. He presents an original analysis of what it means to treat humanity as an end in itself, and examines the implications both for Kant scholarship and for practical guidance on specific moral issues.

In this classic text, Kant sets out to articulate and defend the Categorical Imperative - the fundamental principle that underlies moral reasoning - and to lay the foundation for a comprehensive account of justice and human virtues. This new edition and translation of Kant's work is designed especially for students. An extensive and comprehensive introduction explains the central concepts of Groundwork and looks at Kant's main lines of argument. Detailed notes aim to clarify Kant's thoughts and to correct some common (...) misunderstandings of his doctrines. (shrink)

The Metaphysics of Morals is Kant's major work in applied moral philosophy in which he deals with the basic principles of rights and of virtues. It comprises two parts: the 'Doctrine of Right', which deals with the rights which people have or can acquire, and the 'Doctrine of Virtue', which deals with the virtues they ought to acquire. Mary Gregor's translation, revised for publication in the Cambridge Texts in the History of Philosophy series, is the only complete translation of the (...) whole text, and includes extensive annotation on Kant's difficult and sometimes unfamiliar vocabulary. A new introduction by Roger Sullivan sets the work in its historical and philosophical context. This volume will be of wide interest to students of ethics and of legal and political philosophy.

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 search for and establish the supreme principle of morality, the categorical imperative. Kant argues that every human being is an end in himself or herself, never to be used as a means by others, and that moral obligation is an expression of the (...) human capacity for autonomy or self-government. This edition presents the acclaimed translation of the text by Mary Gregor, together with an introduction by Christine M. Korsgaard that examines and explains Kant's argument. (shrink)

"The moral principle stating that it is a duty to tell the truth would make any society impossible if that principle were taken singly and unconditionally. We have proof of this in the very direct consequences which a German philosopher has drawn from this principle. This philosopher goes as far as to assert that it would be a crime to tell a lie to a murderer who asked whether our friend who is being pursued by the murderer had taken refuge (...) in our house.".

In a dynamic world, mechanisms allowing prediction of future situations can provide a selective advantage. We suggest that memory systems differ in the degree of flexibility they offer for anticipatory behavior and put forward a corresponding taxonomy of prospection. The adaptive advantage of any memory system can only lie in what it contributes for future survival. The most flexible is episodic memory, which we suggest is part of a more general faculty of mental time travel that allows us not only (...) to go back in time, but also to foresee, plan, and shape virtually any specific future event. We review comparative studies and find that, in spite of increased research in the area, there is as yet no convincing evidence for mental time travel in nonhuman animals. We submit that mental time travel is not an encapsulated cognitive system, but instead comprises several subsidiary mechanisms. A theater metaphor serves as an analogy for the kind of mechanisms required for effective mental time travel. We propose that future research should consider these mechanisms in addition to direct evidence of future-directed action. We maintain that the emergence of mental time travel in evolution was a crucial step towards our current success. (shrink)

Following the September 2001 terrorist attacks on the United States, much support for torture interrogation of terrorists has emerged in the public forum, largely based on the “ticking bomb” scenario. Although deontological and virtue ethics provide incisive arguments against torture, they do not speak directly to scientists and government officials responsible for national security in a utilitarian framework. Drawing from criminology, organizational theory, social psychology, the historical record, and my interviews with military professionals, I assess the potential of an official (...) U.S. program of torture interrogation from a practical perspective. The central element of program design is a sound causal model relating input to output. I explore three principal models of how torture interrogation leads to truth: the animal instinct model, the cognitive failure model, and the data processing model. These models show why torture interrogation fails overall as a counterterrorist tactic. They also expose the processes that lead from a precision torture interrogation program to breakdowns in key institutions—health care, biomedical research, police, judiciary, and military. The breakdowns evolve from institutional dynamics that are independent of the original moral rationale. The counterargument, of course, is that in a society destroyed by terrorism there will be nothing to repair. That is why the actual causal mechanism of torture interrogation in curtailing terrorism must be elucidated by utilitarians rather than presumed. (shrink)

Immanuel Kant (1724–1804) argued that moral requirements are based on a standard of rationality he dubbed the “Categorical Imperative” (CI). Immorality thus involves a violation of the CI and is thereby irrational. Other philosophers, such as Locke and Hobbes, had also argued that moral requirements are based on standards of rationality. However, these standards were either desirebased instrumental principles of rationality or based on sui generis rational intuitions. Kant agreed with many of his predecessors that an analysis of practical reason (...) will reveal only the requirement that rational agents must conform to instrumental principles. Yet he argued that conformity to the CI (a non-instrumental principle) and hence to moral requirements themselves, can nevertheless be shown to be essential to rational agency. This argument was based on his striking doctrine that a rational will must be regarded as autonomous, or free in the sense of being the author of the law that binds it. The fundamental principle of morality — the CI — is none other than the law of an autonomous will. Thus, at the heart of Kant's moral philosophy is a conception of reason whose reach in practical affairs goes well beyond that of a Humean ‘slave’ to the passions. Moreover, it is the presence of this self-governing reason in each person that Kant thought offered decisive grounds for viewing each as possessed of equal worth and deserving of equal respect.

After the events of 9/11, the concept of torture has emerged as one that is both pertinent and provoking. National polls have shown that some Americans support torture in some situations, though the majority still stand opposed. Torture has not received a tremendous amount of discussion in the philosophical literature, though I suspect that the leftward slant of academia would, for the most part, ensure limited support for torture. In this paper, I would like to first discuss why torture is (...) an important issue and then advance an argument that supports torture in limited cases. (shrink)

Traditionally, the manufacturer/operator of a machine is held (morally and legally) responsible for the consequences of its operation. Autonomous, learning machines, based on neural networks, genetic algorithms and agent architectures, create a new situation, where the manufacturer/operator of the machine is in principle not capable of predicting the future machine behaviour any more, and thus cannot be held morally responsible or liable for it. The society must decide between not using this kind of machine any more (which is not a (...) realistic option), or facing a responsibility gap, which cannot be bridged by traditional concepts of responsibility ascription.

What psychological and philosophical significance should we attach to recent efforts at computer simulations of human cognitive capacities? In answering this question, I find it useful to distinguish what I will call "strong" AI from "weak" or "cautious" AI. According to weak AI, the principal value of the computer in the study of the mind is that it gives us a very powerful tool. For example, it enables us to formulate and test hypotheses in a more rigorous and precise fashion. (...) But according to strong AI, the computer is not merely a tool in the study of the mind; rather, the appropriately programmed computer really is a mind, in the sense that computers given the right programs can be literally said to.

This article considers the issue of opacity as a problem for socially consequential mechanisms of classification and ranking, such as spam filters, credit card fraud detection, search engines, news trends, market segmentation and advertising, insurance or loan qualification, and credit scoring. These mechanisms of classification all frequently rely on computational algorithms, and in many cases on machine learning algorithms to do this work. In this article, I draw a distinction between three forms of opacity: opacity as intentional corporate or state (...) secrecy, opacity as technical illiteracy, and an opacity that arises from the characteristics of machine learning algorithms and the scale required to apply them usefully. The analysis in this article gets inside the algorithms themselves. I cite existing literatures in computer science, known industry practices, and do some testing and manipulation of code as a form of lightweight code audit. I argue that recognizing the distinct forms of opacity that may be coming into play in a given application is a key to determining which of a variety of technical and non-technical solutions could help to prevent harm.

Chapter 1 of this book argued that moral philosophy should be based on seven principles of theory selection adapted from the sciences. Chapter 2 argued that these principles support basing normative moral philosophy on a particular problem of diachronic instrumental rationality: the ‘problem of possible future selves.’ Chapter 3 argued that a new moral principle, the Categorical-Instrumental Imperative, is the rational solution to this problem. Chapter 4 argued that the Categorical-Instrumental Imperative has three equivalent formulations akin to but superior to (...) Kant’s formulations of the Categorical Imperative. Chapter 5 argued that my principle’s three formulations make it rational to adopt a Moral Original Position to derive moral principles. The present chapter derives Four Principles of Fairness from the Moral Original Position--principles of coercion minimization, mutual assistance, fair negotiation, and virtue—and unifies them into a single principle of rightness: Rightness as Fairness. Finally, this chapter argues that Rightness as Fairness entails a novel approach to applied ethics called ‘principled fair negotiation’, illustrating how the theory provides a plausible new framework for addressing applied cases including lying, suicide, trolleys, torture, distribution of scarce resources, poverty, and the ethical treatment of animals.

In information societies, operations, decisions and choices previously left to humans are increasingly delegated to algorithms, which may advise, if not decide, about how data should be interpreted and what actions should be taken as a result. More and more often, algorithms mediate social processes, business transactions, governmental decisions, and how we perceive, understand, and interact among ourselves and with the environment. Gaps between the design and operation of algorithms and our understanding of their ethical implications can have severe consequences (...) affecting individuals as well as groups and whole societies. This paper makes three contributions to clarify the ethical importance of algorithmic mediation. It provides a prescriptive map to organise the debate. It reviews the current discussion of ethical aspects of algorithms. And it assesses the available literature in order to identify areas requiring further work to develop the ethics of algorithms.

This book argues that moral philosophy should be based on seven scientific principles of theory selection. It then argues that a new moral theory—Rightness as Fairness—satisfies those principles more successfully than existing theories. Chapter 1 explicates the seven principles of theory-selection, arguing that moral philosophy must conform to them to be truth-apt. Chapter 2 argues those principles jointly support founding moral philosophy in known facts of empirical moral psychology: specifically, our capacities for mental time-travel and modal imagination. Chapter 2 then (...) shows that these capacities present human decisionmakers with a problem of diachronic rationality that includes but generalizes beyond, L.A. Paul’s problem of transformative experience: a problem that I call “the problem of possible future selves.” Chapter 3 then argues that a new principle of rationality—the Categorical-Instrumental Imperative—is the only rational solution to this problem, as it requires our present and future selves to forge and uphold a recursive, bi-directional contract with each another given mutual recognition of the problem. Chapter 4 then shows that the Categorical-Instrumental Imperative has three identical formulations analogous but superior to Immanuel Kant’s various formulations of his ‘categorical imperative.’ Chapter 5 shows that these unified formulas jointly entail a particular test of moral principles: a Moral Original Position similar to John Rawls’ famous ‘original position’, but which avoids a variety of problems with Rawls' model. Chapter 6 then shows that the Moral Original Position generates Four Principles of Fairness, which can then be combined into a single principle of moral rightness: Rightness as Fairness. This new conception of rightness is shown to reconcile four dominant moral frameworks (deontology, consequentialism, virtue ethics, and contractualism), as well as entail a new method of moral decisionmaking for applied ethics: a method of “principled fair negotiation” according to which applied ethical issues cannot be wholly resolved through principled debate, but must instead be resolved by actual negotiation and compromise. This method is then argued to generate novel, nuanced analyses of a variety of applied moral issues, including trolley cases, torture, and the ethical treatment of nonhuman animals. Chapter 7 then shows that Rightness as Fairness reconciles three leading political frameworks—libertarianism, egalitarianism, and communitarianism—showing how all three embody legitimate moral ideals that can, and should, be fairly negotiated against each other to settle the scope, and nature, of domestic, international, and global justice on an ongoing, iterated basis. Finally, Chapter 8 argues that Rightness as Fairness satisfies all seven of the principles of theory-selected defended in Chapter 1 more successfully than rival theories. (shrink)

Torture used to be incompatible with American values. Our Bill of Rights forbids cruel and unusual punishment, and that has come to include all forms of corporal punishment except prison and death by methods purported to be painless. Americans and our government have historically condemned states that torture; we have granted asylum or refuge to those who fear it. The Senate ratified the Convention Against Torture, Congress enacted antitorture legislation, and judicial opinions spoke of "the dastardly and totally inhuman act (...) of torture.” Then came September 11.

A detailed, clear, and comprehensive overview of the current philosophical debate on. The question of when, and under what circumstances, the practice of torture might be justified has received a great deal of attention in the last decade in both academia and in the popular media. Many of these discussions are, however, one-sided with other perspectives either ignored or quickly dismissed with minimal argument. In On the Ethics of Torture, Uwe Steinhoff provides a complete account of the philosophical debate surrounding (...) this highly contentious subject. Steinhoff’s position is that torture is sometimes, under certain narrowly circumscribed conditions, justified, basing his argument on the right to self-defense. His position differs from that of other authors who, using other philosophical justifications, would permit torture under a wider set of conditions. After having given the reader a thorough account of the main arguments for permitting torture under certain circumstances, Steinhoff explains and addresses the many objections that have been raised to employing torture under any circumstances. This is an indispensible work for anyone interested in one of the most controversial subjects of our times. (shrink)

According to the standard reading of Kant's formula of universal law (FUL), positive duties can be derived from FUL. In this article, I argue that the standard reading does not work. In the first section, I articulate FUL and what I mean by a positive duty. In the second section, I set out an intuitive version of the standard reading of FUL and argue that it does not work. In the third section, I set out a more rigorous version of (...) the standard reading of FUL and argue that even this more rigorous version does not work. (shrink)

Kant offers the following argument for the formula of humanity (FH): Each rational agent necessarily conceives of her own rational nature as an end in itself and does so on the same grounds as every other rational agent, so all rational agents must conceive of one another's rational nature as an end in itself. As it stands, the argument appears to be question-begging and fallacious. Drawing on resources from the formula of universal law (FUL) and Kant's claims about the primacy (...) of duties to oneself, I propose a contractualist reconstruction of this puzzling line of reasoning.

Law, Economics, and Morality examines the possibility of combining economic methodology and deontological morality through explicit and direct incorporation of moral constraints into economic models. Economic analysis of law is a powerful analytical methodology. However, as a purely consequentialist approach, which determines the desirability of acts and rules solely by assessing the goodness of their outcomes, standard cost-benefit analysis is normatively objectionable. Moderate deontology prioritizes such values as autonomy, basic liberties, truth-telling, and promise-keeping over the promotion of good outcomes. It (...) holds that there are constraints on promoting the good. Such constraints may be overridden only if enough good is at stake. While moderate deontology conforms to prevailing moral intuitions and legal doctrines, it is arguably lacking in methodological rigor and precision. Eyal Zamir and Barak Medina argue that the normative flaws of economic analysis can be rectified without relinquishing its methodological advantages and that moral constraints can be formalized so as to make their analysis more rigorous. They discuss various substantive and methodological choices involved in modeling deontological constraints. Zamir and Medina propose to determine the permissibility of any act or rule infringing a deontological constraint by means of mathematical threshold functions. Law, Economics, and Morality presents the general structure of threshold functions, analyzes their elements and addresses possible objections to this proposal. It then illustrates the implementation of constrained CBA in several legal fields, including contract law, freedom of speech, antidiscrimination law, the fight against terrorism, and legal paternalism.

It is sometimes argued that virtue ethics is incapable of 'telling us what to do'. I explore what this could mean, and come to the conclusion that virtue ethics does enable this, in the only sense in which it is something which we would reasonably want in an ethical theory.

The implementation of moral decision making abilities in artificial intelligence (AI) is a natural and necessary extension to the social mechanisms of autonomous software agents and robots. Engineers exploring design strategies for systems sensitive to moral considerations in their choices and actions will need to determine what role ethical theory should play in defining control architectures for such systems. The architectures for morally intelligent agents fall within two broad approaches: the top-down imposition of ethical theories, and the bottom-up building of (...) systems that aim at goals or standards which may or may not be specified in explicitly theoretical terms. In this paper we wish to provide some direction for continued research by outlining the value and limitations inherent in each of these approaches. (shrink)

This paper is concerned with the normative content of Kant's formula of humanity (FH). More specifically, does FH, as some seem to think, imply the specific and rigid prescriptions in 'standard' deontological theories? To this latter question, I argue, the answer is 'no'. I propose reading FH largely through the formula of autonomy and the formula of the kingdom of ends, where I understand FA to describe the nature of the capacity of humanity-a capacity for self-governance. The latter, I suggest, (...) is akin to the capacity for planning and intentional action described in Michael Bratman's work. A significant part of what FH requires, I then propose, is that we exercise these capacities for planning in such a way that we accommodate and coordinate with the (permissible) plans and intentions of others. Kant himself, as do many commentators, emphasizes the idea that our human capacities give us a distinctive kind of value. On my interpretation, by contrast, what is fundamentally important is not the value of the capacities but rather what they make possible: distinctive ways of mistreating (using) persons, but also a distinctive kind of morally desirable relationship.

This paper is a summary and evaluation of work presented at the AAAI 2005 Fall Symposium on Machine Ethics that brought together participants from the fields of Computer Science and Philosophy to the end of clarifying the nature of this newly emerging field and discussing different approaches one could take towards realizing the ultimate goal of creating an ethical machine.

Kant's Formula of Universal Law is shown to be an inadequate condition for morality because it uses the wrong scope for a universal qualifier, ranging only over the behavior of a set of agents in a world. If it instead ranges over the behavior of all possible agents, then we arrive at the stronger condition that a maxim is morally acceptable just if we can will, not just that all agents follow it simultaneously, but that any agent in any situation (...) may follow it--including, notably, in situations where some other agents are not following it. This stronger formulation avoids some of the counter-examples which Kant's formula is subject to. -/- Author's later note: the argument of this article is improved upon and essentially superseded by his later works on this topic (2012, 2013).
