Consequentialists oppose while absolutists and deontologists rely upon double-effect reasoning (DER) to address hard cases in which good inextricably binds with evil (such as destroying a legitimate military target while concomitantly and foreseeably killing innocents). This book addresses the history, application, and philosophical controversy concerning DER. It traces both the origin of DER in the thought of Aquinas and its development by subsequent ethicists. Considering consequentialist criticisms, proportionalism, and recent revisions of double effect, the book argues at length for the reasonableness of DER, particularly the intended/foreseen distinction. Intent is distinguished from foresight, and this distinction is applied to the classic cases of terror and tactical bombing. Most importantly, the book establishes the ethical relevance of this distinction, grounding its import both in broadly Aristotelian-Thomistic features of action as voluntary, and in a Kantian focus on the victim as an end in himself. The book also considers typically neglected albeit intriguing issues such as DER’s application to allowings and how constitutional legal systems that incorporate exceptionless norms employ a legal analogue to DER.Less

This chapter explores the philosophical tradition of virtue ethics to link the relevant discussion to bioethics, the idea of human flourishing, and the principles of practical reason, justice, and equity. It argues that a dynamic understanding of health, promoting empowerment and capacity building, should present us with a primary bioethical endeavour. This position brings to the foreground important questions as to the ways bioethics should be governed at the international level, whilst capturing the pluralist content of secular bioethics by means of stressing the importance of participation and deliberation when facing relevant regulatory dilemmas.Less

This book traces a complex of issues surrounding moral agency from Kant through Schelling to Kierkegaard. There are two complementary projects. The first is to clarify the contours of German idealism as a philosophical movement by examining the motivations not only of its beginning, but also of its end. In tracing the motivations for the transition to mid-19th century post-idealism to Schelling’s middle and late periods and, ultimately, back to a problem originally presented in Kant, it shows the causes of the demise of that movement to be the same as the causes of its rise. In the process, it presents the most detailed discussion to date of the moral psychology and moral epistemology of Schelling’s work after 1809. The second project — which is simply the first viewed from a different angle — is to trace the sources of Kierkegaard’s theory of agency and his criticism of philosophical ethics to this same complex of issues in Kant and post-Kantian idealism. In the process, it is argued that Schelling’s influence on Kierkegaard was greater than has been thought, and builds a new understanding of Kierkegaard’s project in his pseudonymous works on the basis of this revised picture of their historical background.Less

Moral philosophy has long treated principles as indispensable for understanding its subject matter. However, the underlying assumption that this is the best approach has received almost no defence, and has been attacked by particularists who argue that the traditional link between morality and principles is little more than an unwarranted prejudice. This book meets this particularist challenge head on and defends a distinctive view called ‘generalism as a regulative ideal’. After cataloguing the wide array of views that have gone under the heading ‘particularism’, the reasons why the main particularist arguments fail to establish their conclusions are explained. Generalism as a regulative ideal incorporates what is most insightful in particularism (e.g., the possibility that reasons are context sensitive - ‘holism about reasons’) while rejecting every major particularist doctrine. The book resists the excesses of hyper-generalist views according to which moral thought is constituted by allegiance to a particular principle or set of principles. It argues that in so far as moral knowledge and wisdom are possible, all of morality can and should be codified in a manageable set of principles, even if we are not yet in possession of those principles. Such principles are not objects of mere curiosity, but play an important role in guiding the virtuous agent.Less

This book answers some of the oldest questions in moral philosophy. Claiming that a fundamental issue in normative ethics is what ultimate reasons for action we might have, it argues that the best statements of such reasons will not employ moral concepts. The book investigates and explains the nature of reasons themselves; its account of how we come to know them combines an intuitionist epistemology with elements of Pyrrhonist scepticism. It defends a hedonistic theory of well-being and an account of practical reason according to which we can give some, though not overriding, priority to our own good over that of others. The book develops original lines of argument within a framework of some traditional but currently less popular views.Less

The thesis of this book is that whether or not someone knows a proposition at a given time is in part determined by his or her practical interests, i.e., by how much is at stake for that person at that time. Thus, whether a true belief is knowledge is not merely a matter of supporting beliefs or reliability; in the case of knowledge, practical rationality and theoretical rationality are intertwined. This thesis, called Interest-Relative Invariantism about knowledge, is defended against alternative accounts of the phenomena that motivate it, such as the claim that knowledge attributions are linguistically context-sensitive and the claim that the truth of a knowledge claim is somehow relative to the person making the claim. The strategies available for resolving skepticism to the strategies available for resolving other philosophical paradoxes are compared. For example, contextualist solutions to the sorites paradox and the liar paradox, as well as interest-relative accounts of the sorites paradox are considered. It is shown that the argument for the interest-relative character of epistemic notions is not the result of an application of a general strategy for resolving philosophical quandaries, but arises from the distinctive nature of epistemic properties.Less

This book shows that ascriptions of beliefs and intentions are normative in that they have normative implications. Since there is no more to believing something and intending something than meeting the conditions for falling under, respectively, the concepts of so believing and of so intending, it follows that there is a normative dimension to the states of believing and intending. The idea is extended to all propositional attitudes via the assumption that attitudes with conceptual content have a normative dimension. The resulting picture is applied to issues about understanding people in terms of rationalizing explanations of what they think or do. An important concern is to explain how the fact that agents’ attitudes rationalize the performance of actions or the formation of beliefs on their part can be relevant to the explanation of what they do or believe. Along the way, there are discussions of normative commitments, differences between reasons for action and reasons for belief, practices conceived as essentially rule-governed activities, simulation theory, and the limits of mentalistic explanation.Less

The literature on theoretical reason has been dominated by epistemological concerns, treatments of practical reason by ethical concerns. This book overcomes the limitations of dealing with each separately. It sets out a comprehensive theory of rationality applicable to both practical and theoretical reason. In both domains, the book explains how experience grounds rationality, delineates the structure of central elements, and attacks the egocentric conception of rationality. It establishes the rationality of altruism and thereby supports major moral principles. The concluding part describes the pluralism and relativity the book's conception of rationality accommodates and, taking the unified account of theoretical and practical rationality in that light, constructs a theory of global rationality — the overall rationality of persons.Less

This book presents a study of Hegel's hugely influential but notoriously difficult Phenomenology of Spirit. Hegel describes the method of this work as a ‘way of despair’, meaning that the reader who undertakes its inquiry must be open to the experience of self-loss through it. Whereas the existential dimension of Hegel's work has often been either ignored or regarded as romantic ornamentation, this book argues that it belongs centrally to Hegel's attempt to fulfil a demanding epistemological ambition. With his Critique of Pure Reason, Kant expressed a new epistemological demand with respect to rational knowledge and presented a new method for meeting this demand. This book reconstructs Hegel's objection to Kant's Critical Philosophy, according to which Kant's way of meeting the epistemological demand of philosophical critique presupposes subjectivism, that is, presupposes the restriction of our knowledge to things as they are merely for us. Whereas Hegel in his early Jena writings rejects Kant's critical project altogether on this basis, he comes to see that the epistemological demand expressed in Kant's project must be met. This book argues that Hegel's method in the Phenomenology of Spirit takes shape as his attempt to meet the epistemological demand of Kantian critique without presupposing subjectivism. The key to Hegel's transformation of Kant's critical procedure, by virtue of which subjectivism is to be avoided, is precisely the existential or self-transformational dimension of Hegel's criticism, the openness of the criticizing subject to being transformed through the epistemological procedure.Less

Hilary of Poitiers (c300–368), who was instrumental in shaping the development of pro-Nicene theology in the West, combined two separate works, a treatise on faith (De Fide) and a treatise against the “Arians” (Adversus Arianos), to create De Trinitate; his chief theological contribution to the 4th-century Trinitarian debates. Scholars have long recognized the presence of these two treatises in Hilary's De Trinitate but have been unable to settle the questions of when and why Hilary did this. This book addresses these questions concerning the structure and chronology of De Trinitate by situating Hilary's treatise in its historical and theological context and offering a close reading of the text. It is argued that De Fide was written in 356 following Hilary's condemnation at the synod of Béziers and prior to receiving a decision on his exile from the Emperor. When Hilary arrived in exile, he wrote a second work, Adversus Arianos. Following the synod of Sirmium in 357 and his collaboration with Basil of Ancyra in early 358, Hilary recast his efforts and began to write De Trinitate. He decided to incorporate his two earlier works, De Fide and Adversus Arianos, into this project. Toward that end, he returned to his earlier works and drastically revised their content by adding new prefaces and new theological and exegetical material to reflect his mature pro-Nicene theology. These revisions and textual alterations have never before been acknowledged in the scholarship on De Trinitate.Less

This a research study about logic. Logic is both part of and has roles in many disciplines, including inter alia, mathematics, computing, and philosophy. The topic covered here — the mathematical theory of reductive logic and proof-search — draws upon the techniques and cultures of all three disciplines, but is mainly about mathematics and computation. Since its earliest presentations, mathematical logic has been formulated as a formalization of deductive reasoning: given a collection of hypotheses, a conclusion is derived. However, the advent of computational logic has emphasized the significance of reductive reasoning: given a putative conclusion, what are sufficient premises? Whilst deductive systems typically have a well-developed semantics of proofs, reductive systems are typically well-understood only operationally. Typically, a deductive system can be read as a corresponding reductive system. The process of calculating a proof of a given putative conclusion, for which non-deterministic choices between premises must be resolved, is called proof-search and is an essential enabling technology throughout the computational sciences. This study suggests that the reductive view of logic is as fundamental as the deductive view, and discusses some of the problems that must be addressed in order to provide a semantics of proof-searches of comparable value to the corresponding semantics of proofs. Just as the semantics of proofs is intimately related to the model theory of the underlying logic, so too should be the semantics of reductions and of proof-search. The study discusses how to solve the problem of providing a semantics for proof-searches in intuitionistic logic, which adequately models both not only the logical but also via an embedding of intuitionistic reductive logic into classical reductive logic, the operational aspects, i.e., control of proof-search, of the reductive system. It concludes with a naturally motivated example of our semantics of proof-search: a class of games.Less

Jürgen Habermas seeks to defend the Enlightenment and with it an “emphatical”, “uncurtailed” conception of reason against the post-modern critique of reason on the one hand, and against so-called scientism (which would include critical rationalism and the greater part of analytical philosophy) on the other. His objection to the former is that it is self-contradictory and politically defeatist; his objection to the latter is that, thanks to a standard of rationality derived from the natural sciences or from Weber's concept of purposive rationality, it leaves normative questions to irrational decisions. Wishing to offer an alternative, Habermas tries to develop a theory of communicative action that can clarify the normative foundations of a critical theory of society as well as provide a fruitful theoretical framework for empirical social research. This study is a comprehensive and detailed analysis and a sustained critique of Habermas' philosophical system starting with his pragmatist turn in the seventies. It clearly and precisely depicts its long path from an analysis of speech acts to a discourse theory of law and the democratic constitutional state via the theory of communicative action, discourse ethics, and the attempts to apply the approach to, and support it with, empirical theories.Less

Long claimed to be the ‘dominant conception of practical reason’, the Humean theory that reasons for action are instrumental, or explained by desires, is the basis for a range of worries about the objective prescriptivity of morality. As a result, it has come under intense attack over the last quarter century. A wide variety of arguments have been advanced which purport to show that it is false, or surprisingly, even that it is incoherent. This book explores the viability of this central Humean thesis about reasons in the face of this critical onslaught. Its thesis is that the purportedly general objections to the Humean theory actually turn on substantive assumptions that are non-essential to the theory, and in fact are better rejected on independent grounds. In the course of advancing this argument, the book develops and defends a version of the Humean theory that withstands these objections. If this is right, then the commitments of the Humean theory have been widely and deeply misunderstood. Along the way, the book raises and addresses questions about the fundamental structure of reasons, the nature of normative explanations, the aims of and challenges facing reductive views in metaethics, the weight of reasons, the nature of desire, moral epistemology, and most importantly, the relationship between agent-relational and agent-neutral reasons for action.Less

This book offers the first sustained jurisprudential inquiry into Islamic natural law theory. It introduces readers to competing theories of Islamic natural law theory based on close readings of Islamic legal sources from as early as the ninth and tenth centuries C.E. In popular debates about Islamic law, modern Muslims perpetuate an image of Islamic law as legislated by God, to whom the devout are bound to obey. Reason alone cannot obligate obedience; at most it can confirm or corroborate what is established by source texts endowed with divine authority. This book shows, however, that premodern Sunni Muslim jurists were not so resolute. They asked whether and how reason alone can be the basis for asserting the good and the bad, and thereby obligations and prohibitions of the Shari'a. They theorized about the authority of reason amidst competing theologies of God. For these jurists, nature became the link between the divine will and human reason. Nature is the product of God's creative power. Nature is created by God and reflects his goodness; consequently nature is fused with both fact and value. As a divinely created good, nature can be investigated to reach both empirical and normative conclusions about the good to be pursued. By recasting the Islamic legal tradition in terms of legal philosophy, the book sheds substantial light on an uncharted tradition of natural law theory and offers critical insights into contemporary global debates about Islamic law and reform.Less

This is a study of the key features of the moral psychology and metaethics of three important medieval Jewish philosophers, Saadia Gaon, Bahya ibn Pakuda, and Moses Maimonides. They are selected because of the depth and subtlety of their thought and because of their relevance to central, enduring issues in moral philosophy. The book examines their views of freedom of the will, the virtues, the rationality of moral requirements, and the relation between rational justification and revelation. Their appropriations of Neoplatonic and Aristotelian thought are explicated, showing how their theistic commitments make crucial differences to moral psychology and moral epistemology. All three thinkers developed rationalistic philosophies and sought to show how Judaism does not include doctrines in conflict with reason. Maimonides receives the fullest attention, given that he articulated the most systematic and influential accounts of the main issues. While explicating the main claims and arguments of these thinkers, the book also shows the respects in which their thought remains relevant to several important issues and debates in moral philosophy. These thinkers' views of ‘the reasons of the commandments’ (in Torah) include resources for a sophisticated moral epistemology of tradition. The points of contact and contrast between medieval Jewish moral thought and the practical wisdom approach to moral theory and also natural law approaches are examined in detail.Less

The cognitive and neural sciences have been on the brink of a paradigm shift for over a decade. This book is intended to help galvanize the forces of dynamical systems theory, cognitive and computational neuroscience, connectionism, and ecological psychology that are needed to complete this paradigm shift. The book lays bare the fact that comprehending a spoken sentence, understanding a visual scene, or just thinking about the day's events involves the serial coalescing of different neuronal activation patterns, i.e., a state-space trajectory that flirts with a series of point attractors. As a result, the brain cannot help but spend most of its time instantiating patterns of activity that are in between identifiable mental states rather than in them. The chapters are arranged to present a systematic overview of how perception, cognition, and action are partially overlapping segments of one continuous mental flow, rather than three distinct mental systems. The early chapters provide experiential demonstrations of the gray areas in mental activity that happen in between discretely labeled mental events, as well as geometric visualizations of attractors in state space that make the dynamical-systems framework seem less mathematically abstract. The middle chapters present scores of behavioral and neurophysiological studies that portray the continuous temporal dynamics inherent in categorization, language comprehension, visual perception, as well as attention, action, and reasoning. The final chapters conclude with discussions of what the mind itself must look like if its activity is continuous in time and its contents are distributed in state space.Less

A growing number of political philosophers favour a view called liberal perfectionism. According to this view, liberal political morality is characterized by a commitment to helping individuals lead autonomous lives and making other valuable choices. This book rejects this widely held view and offers an alternative account of liberal political morality. It argues that the liberal state should not be engaged in determining what constitutes a valuable or worthwhile life nor try to make sure that individuals live up to this ideal. Instead, it should remain neutral on the issue of the good life, and restrict itself to establishing the fair terms within which individuals can pursue their own beliefs about what gives value to their lives. The book thus defends a position known as political liberalism. The first part of the book subjects the liberal perfectionist position to critical scrutiny, advancing three major objections which raise serious doubts about the liberal perfectionist position with regard to autonomy, paternalism, and political legitimacy. The second part of the book presents and defends a distinctive version of political liberalism. In particular, it clarifies and develops political liberalism's central thesis: that political principles, in order to be legitimate, must be publicly justifiable to reasonable people. Drawing on the work of John Rawls, the author offers his own interpretation of this idea, and rebuts some of the main objections that have been pressed against it. In doing so, he provides novel arguments regarding the nature of an overlapping consensus, the structure of political justification, the idea of public reason, and the status of unreasonable persons.Less

Understanding human beings and their distinctive rational and volitional capacities is one of the central tasks of philosophy. The task requires a clear account of such things as reasons, desires, emotions, and motives, and of how they combine to produce and explain human behaviour. Kinds of Reasons offers a fresh and incisive treatment of these issues, focusing in particular on reasons as they feature in contexts of agency. The account offered builds on some important recent work in the area; but it takes its main inspiration from the tradition that receives its seminal contemporary expression in the writings of G. E. M. Anscombe, a tradition that runs counter to the broadly Humean orthodoxy that has dominated the theory of action for the past forty years. The book offers an alternative to the Humean view that our reason for acting are mental states: it explains and develops a distinctive version of the view that our reasons for acting are facts, and defends it against difficulties that have been thought to be insurmountable. In addition, it proposes an account of the relation between reasons and desires, and of the role these play in practical reasoning and in the explanation of action.Less

The conclusion briefly draws together the main conclusions of the book and places them against the background of the questions that dominated action theory for decades after the publication of Davidson's paper ‘Actions, Reasons, and Causes’, namely, whether reasons are causes and whether reason explanations are causal explanations. It is suggested that the questions have often been debated in terms which are muddled due to the lack of nuance in understanding reasons. It is suggested that it would, therefore, be interesting to reassess the questions Davidson put on the table with a clearer grasp of what our reasons for acting are, and a clearer picture of the reasons that explain action and the variety of forms that explanations of action take.Less
