Spinoza was one of the most influential figures of the Enlightenment, but his often obscure metaphysics makes it difficult to understand the ultimate message of his philosophy. Although he regarded freedom as the fundamental goal of his ethics and politics, his theory of freedom has not received sustained, comprehensive treatment. Spinoza holds that we attain freedom by governing ourselves according to practical principles, which express many of our deepest moral commitments. Matthew J. Kisner focuses on this theory and (...) presents an alternative picture of the ethical project driving Spinoza's philosophical system. His study of the neglected practical philosophy provides an accessible and concrete picture of what it means to live as Spinoza's ethics envisioned. (shrink)

Thirteen original essays by leading scholars explore aspects of Spinoza's ethical theory and, in doing so, deepen our understanding of it as the richly rewarding core of his system. They resolve interpretive difficulties, advance longstanding debates, and point the direction for future research.

While Spinoza claims that our good is both what increases our essential power and what helps us to satisfy our desires, he admits that people desire things that do not increase their power. This paper addresses this problem by arguing that Spinoza conceives of desires as expressions of our conatus , so that satisfying our desires necessarily increases our power and vice versa. This reading holds, in opposition to recent work, that Spinoza upholds a desire-satisfaction theory of the good, though (...) an unusual one, since our good is only determined by desires arising from our conatus , in other words, active desires.

Spinoza’s remarks on the exemplar or model of human nature, while few and brief, have far-reaching consequences for his ethics. While commentators have offered a variety of interpretations of the model and its implications, there has been near unanimous agreement on one point, that the identity of the model is the free man, described from E4P66S to E4P73. Since the free man is completely self-determining and, thus, perfectly free and rational, this reading indicates that Spinoza’s ethics sets exceptionally high goals, (...) aiming to make us purely active beings. While this conclusion has been embraced in some quarters—particularly by those who see his ethics as aiming to make us like God—it has also been criticized as intolerant of human weakness and vulnerability. Most work on this subject has been concerned to explain what it means for the free man to serve as the model. This is a difficult task, since Spinoza pointedly claims that it is impossible for human beings to become completely self-determining and, thus, free men. Consequently, it is unclear what implications his claims about the free man have for us, ordinary humans. This paper takes a different approach: I will show that reading the free man as the model of human nature, while intuitively appealing, does not stand up to close scrutiny. The argument for this claim has two prongs: the first asserts that there is not sufficient textual evidence to establish that Spinoza intended the free man to serve as the model; the second asserts that this reading is impossible to reconcile with Spinoza’s other philosophical commitments. In particular, Spinoza holds that we pursue the model of human nature, as well as the general ethical goals of attaining our good and perfection, under the guidance of reason. It would be inconsistent with this claim for Spinoza’s ethics to be founded upon attaining a goal that reason reveals as unattainable and, even, confused. In addition to this negative thesis, I will also defend a positive one: the model of human nature should rather be understood as representing the greatest possible perfection of our nature as it is revealed by reason. The free man meanwhile should be understood as working toward a different goal, determining what is good and bad in the emotions. In making this claim, we offer a very different picture of Spinoza’s ethical goals, for reason shows that our nature is conatus, which is a finite mode and, as such, necessarily determined by and passive with respect to other finite modes. Consequently, a model derived from reason will represent the perfection of this nature as passive to some extent. In this way, I provide a picture of Spinoza’s ethics that takes a more sympathetic view of human weakness and vulnerability. (shrink)

The jumping off point for this paper is a metaphysical puzzle for this view and for any relational theory of autonomy. Most of the time, our relationships with others are reciprocal in the sense that they involve activity and passivity, acting on others and being acted on by them. Consequently, claiming that our relationships with others are constitutive of our autonomy implies that being passively affected is also constitutive of our autonomy. But this seems problematic, perhaps even contradictory, because autonomy (...) is equivalent to self-determination, which is a kind of activity: how can being passively affected be constitutive of our self-determination and activity? In Spinoza, the difficulty arises in his theory of striving. Spinoza’s view that relationships are constitutive of our freedom and autonomy implies that our relationships—and being passively affected in these relationships—are constitutive of our striving, in which our freedom and autonomy consist. But how can passivity be constitutive of our striving, which is a kind of activity? -/- To resolve the apparent paradox, I look to the Aristotelian notion that the natures of things make them subject or susceptible to undergoing certain kinds of change. For instance, water, because of its nature, is susceptible to boiling, rather than burning. This implies that a passive or exogenous change—for instance, fire causing the water to boil—is brought about partly from the nature and activity of the patient: the water is active in the sense of determining it to boil, rather than burn. This way of thinking implies that changes arise cooperatively from both internal and external sources, which eliminates the apparent contradiction in claiming that change can be both active and passive. The paper shows that Spinoza’s theory of striving shares the gist of this Aristotelian commitment by claiming that our nature is active in determining us to certain effects, even when the effects originate externally. Consequently, like Aristotle, Spinoza does not see passivity and activity as mutually exclusive, which eliminates the apparent paradox. The paper concludes by considering how this more Aristotelian conception of activity is amenable to relational theories of autonomy. (shrink)

While it is often supposed that Spinoza understood a life of virtue as one of pure activity, with as few passions as possible, this paper aims to make explicit how the passions for Spinoza contribute positively to our virtue. This requires, first, explaining how a passion can increase our power, given Spinoza’s view on the passions generally, which, in turn, requires coming to terms with the problem of passive pleasure, that is, the problem of explaining how being passive can cause (...) an increase in our power. In brief, this paper will argue that, for Spinoza, even when we are passive, we are somewhat active or, in Spinoza’s language, “adequate” to varying degrees. The passions represent activity because they exercise our understanding by providing us with intelligence about external bodies and our own bodies, in particular, the degree of our bodies’ perfection. It follows that a passion can be sufficiently adequate to bring about an increase in one’s power; in this sense, they can be virtuous. Moreover, this paper will show that the passions can also be virtuous in a moral sense. The view goes roughly as follows: according to Spinoza, the passions serve as a measure of our perfection. Consequently, they play a necessary role in moral reasoning, by indicating which activities increase or hinder our virtue. On this view, a truly virtuous person would require the passions in order to engage consistently in the sorts of activities which increase her power, in particular, following reason. Since this sort of consistency in behavior is necessary for a virtuous character, the passions can be virtuous in the sense that they are necessary aspects of the sort of character which disposes us to act according to reason. (shrink)

Spinoza’s ethical claims rest on a basic set of concepts that he regards as kinds of activity: striving, power, virtue, freedom, perfection, among others. Steven Nadler articulates a standard way of thinking about the relationship between these activity concepts: “a number of terms in Spinoza are co-extensive and refer to the same ideal human condition. We can set up the following equation for Spinoza: virtue = knowledge = activity = freedom = power = perfection. Necessarily, the more virtuous a person (...) is, the more knowledge he has, the more free, active and powerful he is, and the more he has achieved of human perfection.” This paper counters that Spinoza’s various notions of activity are not coextensive and do not refer to the same thing. In particular, Spinoza employs two basic notions of activity: striving and being an adequate cause. While these notions of activity are closely connected, they are not coextensive because a thing can strive without being an adequate cause of an effect. I defend that Spinoza’s various other activity concepts—virtue, perfection, reason and so forth—are pegged to one of these two basic notions of activity, so that Spinoza’s activity concepts are bifurcated into two categories, which are not coextensive with one another. Indeed, the members of each category may not be coextensive with one another. -/- Because these basic activity concepts play a fundamental role in Spinoza’s philosophical claims, this thesis has far-reaching implications. Most notably, the standard way of thinking mentioned above indicates that Spinoza’s basic ethical concepts, such as freedom and virtue, are coextensive with being an adequate cause. Since an adequate cause is the sole cause of some effect, this reading implies that freedom and virtue amount to being a sole cause and, thus, to being causally independent and self-sufficient. I argue, in contrast, that human freedom and virtue are coextensive with striving, which does not require causal independence. On this reading, human freedom and virtue can include instances of causal dependence, which implies that Spinoza’s ethics takes a more favorable view of human dependence, passivity and cooperation.

Spinoza's Ethics is one of the most significant texts of the early modern period, important to history, philosophy, Jewish studies and religious studies. It had a major influence on Enlightenment thinkers and the development of the modern world. In Ethics, Spinoza addresses the most fundamental perennial philosophical questions concerning the nature of God, human beings and a good life. His startling answers synthesize the longstanding traditions of ancient Greek and Jewish philosophy with the developments of the emerging scientific revolution. The (...) resulting philosophical system casts out the willing, personal God of Abrahamic religions and takes up the challenge of reconceiving the natural world and human beings in an entirely secular way. This volume offers a new translation based on a new critical edition, reflecting the state of the art in Spinoza scholarship, and also includes an introduction, chronology and glossary to help make this notoriously difficult text accessible.

This paper is concerned with Descartes’s view on the passions’ moral value, that is, their value with respect to achieving the ethical ends of virtue and happiness. In this regard, there is no question that the passions possess a kind of conative value because of their power to move or incline us in ways that contribute to ethical ends. This paper’s question is whether the passions also contribute to ethical ends in a cognitive sense by informing us of the moral (...) value of things, in other words, telling us whether things are good or bad with respect to the ends of virtue and happiness. The answer to this question is less clear for two reasons. Firstly, in order for the passions to inform us in this way they would have to be the sort of mental state that purports to tell us the way things are, in other words, that contain some sort of presentation or assessment of things. To borrow language from present day philosophy of mind, they would have to be contentful mental states. But this way of thinking about the passions is opposed by a long tradition, running from Descartes’s contemporaries to today, that regards Cartesian passions as purely conative or appetitive movements, along the lines of Thomistic passions. Secondly, even if the passions are contentful, it is not clear whether their contents accurately report the value of things with respect to ethical goals. Descartes frequently warns that the passions provide unreliable ethical guidance because they report on good and evil with respect to more bodily and animalistic aims: bodily health, self-preservation and the continuation of the species In taking up this question, I am guided by the work of Cambridge Platonist, Henry More. More offered a positive assessment of Descartes’s theory of the passions, which served as the basis for More’s ethical theory in the Enchiridion Ethicum. More’s astute reading of Descartes is useful to my investigation both because he reads the Cartesian passions as contentful mental states and because he uses this reading to explain their accuracy and reliability with respect to virtue. Following More's interpretation, I argue that Descartes recognizes a category of passions—including, most notably, the passion of generosity and the passions following from it—that are more ethically reliable and that serve roughly the same ethical functions as the affections of More's boniform faculty.

This paper is concerned with Spinoza’s treatment of a problem in early modern moral philosophy: the potential conflict between the pursuit of happiness and virtue. The problem is that people are thought to attain happiness by pursuing their self-interest, whereas virtue requires them to act with benevolence, for the benefit of others. Given the inevitability that people will have different and often competing interests, how can they be both virtuous and happy and, where the two are in conflict, which should (...) they prefer? While there were an array of treatments of the problem, most agreed on the general strategy of arguing that people’s true interests—as revealed through reason—are not in competition; rather, they coincide, such that promoting the interests of others promotes people’s own interests and vice versa. Such a response aims to show that people’s happiness is best served by being virtuous and their virtue is best served by making themselves happy.Spinoza agreed with the general outline of this solution, equating virtue with power, thereby defining virtuous behavior as the pursuit of one’s own interests. Since, for Spinoza, happiness arises from increasing one’s power, happiness and virtue are necessarily connected. Furthermore, he does not equate virtue and happiness at the expense of benevolence. This point may be overlooked since Spinoza’s single comment in the Ethics on benevolentia is denigrating: he defines benevolence as a desire arising from pity and “in a man who lives under the guidance of reason, pity in itself is useless and bad” . 1 However, we should distinguish Spinoza’s benevolentia, a kind of piteous desire, from a common notion of benevolence as acting to the benefit of others, which he defends.

This paper argues that Shaftesbury differs from other moral sentimentalists (Hutcheson, Hume, Smith) because he conceives of the moral sentiments as partial and first-personal, rather than impartial and spectatorial. This difference is grounded in Shaftesbury’s distinctive notion that moral self-governance consists in the self-examination of soliloquy. Breaking with his Stoic influences, Shaftesbury holds that the moral sentiments play the role of directing and guiding soliloquy. Because soliloquy is first-personal reflection that is directed to achieving happiness, claiming that the moral sentiments (...) direct soliloquy leads Shaftesbury to conceive of the moral sentiments as arising from the internal perspective of an agent focused on her own happiness. This provides Shaftesbury with a stronger framework for understanding moral sentiments, for it avoids the difficulty of explaining why the sentiments of others or those arising from an imagined spectator’s perspective are motivating or authoritative for us.

How are we to understand Descartes' view on the power and scope of reason? According to a common view, Descartes traffics in what I call 'theocentric rationalism.' Theocentric rationalism holds that human reason resembles divine reason, according to which God created the world. A hallmark of this view is the notion that knowledge should be analyzed and evaluated according to the standards of cognition achievable by God. ;My dissertation argues that Descartes resisted treating human reason as resembling divine reason. This (...) is supported by Descartes' theological voluntarism which denies that God is bound by the standards of human reason. Rather, Descartes conceived of reason as a natural power. He argued that reason is a power of mental substances, as much a part of the natural world as powers belonging to their counterpart, bodily substances. This conception of reason led Descartes to a view which I call "naturalistic rationalism." It holds that human knowledge is subject to the constraints and limitations imposed by our natural faculties human knowledge should be analyzed and evaluated according to the standards of cognition achievable by humans, given these limitations. According to my interpretation, Descartes did not seek to justify human reason by recourse to independent standards, such as divine reason. ;My case for this interpretation takes the form of a narrative tracing the development of Descartes' views on reason. Descartes' theory of reason emerged from his first systematic project, the method. Because Descartes held that method must employ the cognitive faculties properly, this early work, particularly the unpublished Regulae ad Directionem Ingenii , provides extensive discussions of reason, its proper function and its limits. I argue that Descartes' mature metaphysical work continued to uphold the central claims of his early theory of reason, in particular, the view that reason is a natural power, subject to natural constraints. ;This reading draws attention to the often neglected philosophical influence of Descartes' close friend, Marin Mersenne. Furthermore, my reading demonstrates the continuity of Descartes' early and later work. Most importantly, my reading allows us to better appreciate the significant differences between Descartes' rationalism and other rationalists. (shrink)

While Spinoza’s political philosophy is often described as liberal, it is not always clear what this label means or whether it is warranted. Calling Spinoza ‘liberal’ implies that he belongs to a historical tradition of political philosophers, who formulated and defended claims, which later became identified as central to political liberalism. Consequently, clarifying how Spinoza is a liberal requires specifying precisely which liberal views he articulated and defended. This paper, first, examines the various ways that commentators have interpreted Spinoza as (...) defending liberal commitments. This examination shows that most commentators describe Spinoza as liberal on the grounds that his politics defends the value of individual political freedom, specifically of speech and thought. The paper, second, considers whether he upholds a claim that is important to contemporary liberalism, what is sometimes called the fundamental liberal principle. The paper concludes that Spinoza does not, which suggests that he does not sit as easily in the liberal tradition as some scholars have suggested. (shrink)

Spinoza’s bold, spirited defense of toleration is an animating theme of the Theological-Political Treatise (TTP) and an important reason for the significant historical impact of the text. But Spinoza’s arguments for toleration can be challenging to discern. True to its title, the TTP offers two main arguments for toleration, one political, the other theological. This paper argues that Spinoza’s theological argument for toleration is closely connected to a distinct and often overlooked argument from pluralism. This paper examines Spinoza’s argument from (...) pluralism and defends that it is more attractive to similar arguments for toleration offered by Bodin and Bayle. It is more attractive than Bodin’s pluralism argument because Spinoza’s allows that religious beliefs and doctrines of faith have a rational justification, which makes possible a more optimistic picture of the prospects for religious disputation. Spinoza’s pluralism argument is also more attractive than Bayle’s argument because Spinoza’s does not regard religious beliefs as justified by sincerity, which means that he does not need to recognize any problematic rights of erroneous conscience, nor is he forced to accept as justified sincere beliefs in persecution or obviously immoral or irreligious beliefs.

In the Ethics, Spinoza famously wrote, “we do not seek or desire anything, because we judge it to be good; on the contrary, we judge a thing to be good because we endeavor it, will it, seek it and desire it.” This passage is widely recognized as asserting some of Spinoza's most important claims about the good, but the precise meaning of the passage is unclear, as interpreters have offered a wide variety of interpretations, often without noting (or even noticing) (...) their disagreements. The central interpretive question is what the key passage has to say about the relationship between desires and judgments of the good. At stake in this question is not just how we understand Spinoza's theory of the good—and by extension, much of his ethical theory – but also how we understand the reception of the scholastic Aristotelian notion that desiring something involves perceiving or thinking it to be good, the “guise of the good thesis”. This paper offers an interpretation of the passage that emphasizes differences between Spinoza and a Hobbesian view of judging the good. Rather, I show – perhaps surprisingly – that Spinoza is closer to the scholastic-Aristotelian tradition. (shrink)

Schmaltz’s excellent book tells a story unfamiliar to most English speaking historians of philosophy. The historical aspect of the story centers on Louis XIV’s 1671 decree opposing anti-Aristotelianism. The decree spoke to the growing popularity of Descartes’s philosophy during the twenty years after his death. Schmaltz examines two figures central to the dissemination and reinterpretation of Descartes’ philosophy at this time: Robert Desgabets and Pierre-Sylvain Regis. The Benedictine Desgabets played an important role in defending Descartes’s controversial views on the eucharist, (...) arguably the catalyst for the 1671 decree. His disciple, Regis, elaborated and propagated Desgabets’s brand of Cartesianism in the face of the political firestorm generated by the decree. (shrink)

In the introductory chapter to this collection, the editors point out that, until recently, most Anglophone Spinoza scholarship has been focused on the metaphysics and epistemology of the Ethics. But according to Kisner and Youpa, Spinoza thought that metaphysics and epistemology were significant chiefly because they are required for understanding the more important part of his project—the ethical doctrine developed in the last three parts of the work. Ethica was so-titled because it is a book about ethics.In recent years, (...) the scholarly community has begun to shift its attention to bring itself more in line with Spinoza's intentions—to focus more directly on his ethical views.

In this essay, I evaluate four central metaethical readings of Spinoza’s moral philosophy in the literature: unqualified anti-realism, qualified anti-realism, qualified realism, and unqualified realism. More specifically, I discuss the metaethical readings of Charles Jarrett (unqualified anti-realism), Matthew Kisner (qualified anti-realism), Jon Miller (qualified realism), and Andrew Youpa (unqualified realism), each of which captures core aspects of this debate. My conclusions are that (1) Spinoza is neither an unqualified anti-realist nor an unqualified realist and (2) Spinoza’s ethical framework (...) represents a qualified synthesis of realist (naturalistic) and anti-realist (affective) features.

Experiences of Depression is a philosophical exploration of what it is like to be depressed. In this important new book, Matthew Ratcliffe develops a detailed account of depression experiences by drawing on work in phenomenology, philosophy of mind and psychology, and several other disciplines.

This chapter describes the attributionist approach to moral responsibility. Works by Pamela Hieronymi, T.M. Scanlon, Angela Smith, and Matthew Talbert are taken to representative of this approach. On the interpretation given here, attributionism is committed to the following: assessments of moral responsibility are, and ought to be, centrally concerned with the morally significant features of an agent’s orientation toward others that are attributable to her, and an agent is eligible for moral praise or blame solely on the basis of (...) these attributions. Attributionism is presented as rejecting the claim that agents are morally responsible only for what is under their voluntary control, as well as the claim that agents are responsible for wrongdoing only if they could have responded to the moral considerations that spoke against your behavior. These supposed conditions on moral responsibility are rejected for the same reason: agents may reveal features of their selves, in a way that is sufficient for moral responsibility, even in cases in which these conditions are not met.

In Real Hallucinations, Matthew Ratcliffe offers a philosophical examination of the structure of human experience, its vulnerability to disruption, and how it is shaped by relations with other people. He focuses on the seemingly simple question of how we manage to distinguish among our experiences of perceiving, remembering, imagining, and thinking. To answer this question, he first develops a detailed analysis of auditory verbal hallucinations (usually defined as hearing a voice in the absence of a speaker) and thought insertion (...) (somehow experiencing one's own thoughts as someone else's). He shows how thought insertion and many of those experiences labeled as "hallucinations" consist of disturbances in a person's senseof being in one type of intentional state rather than another. Ratcliffe goes on to argue that such experiences occur against a backdrop of less pronounced but wider-ranging alterations in the structure of intentionality. In so doing, he considers forms of experience associated with trauma, schizophrenia, and profound grief. The overall position arrived at is that experience has an essentially temporal structure, involving patterns of anticipation and fulfillment that are specific to types of intentional states and serve to distinguish them phenomenologically. Disturbances of this structure can lead to various kinds of anomalous experience. Importantly, anticipation-fulfillment patterns are sustained, regulated, and disrupted by interpersonal experience and interaction. It follows that the integrity of human experience, including the most basic sense of self, is inseparable from how we relate to other people and to the social world as a whole. (shrink)

The view that it is better for life to be created free of disability is pervasive in both common sense and philosophy. We cast doubt on this view by focusing on an influential line of thinking that manifests it. That thinking begins with a widely-discussed principle, Procreative Beneficence, and draws conclusions about parental choice and disability. After reconstructing two versions of this argument, we critique the first by exploring the relationship between different understandings of well-being and disability, and the second (...) by more briefly focusing on the idea of a significant reason. By placing these results against the broader historical and ongoing contexts in which the lives of those with disabilities have been deemed of inferior quality, we conclude with a call for greater humility about disability and well-being in thought and practice.

Why do war crimes occur? Are perpetrators of war crimes always blameworthy? In an original and challenging thesis, this book argues that war crimes are often explained by perpetrators' beliefs, goals, and values, and in these cases perpetrators may be blameworthy even if they sincerely believed that they were doing the right thing.

Most people would agree that a small child, or a cognitively impaired adult, is less responsible for their actions, good or bad, than an unimpaired adult. But how do we explain that difference, and how far can anyone be praised or blamed for what they have done? In this fascinating introduction, Matthew Talbert explores some of the key questions shaping current debates about moral responsibility, including: What is free will, and is it required for moral responsibility? Are we responsible (...) for the unforeseen consequences of our actions? Is it fair to blame people for doing what they believe is right? And are psychopaths open to blame? As Talbert argues, we are morally responsible for our actions when they are related to us in particular ways: when our actions express our true selves, for example, or when we exercise certain kinds of control over them. It is because we bear these relationships to our actions that we are open to praise and blame. _Moral Responsibility_ will be an important resource for students and researchers in ethics, moral psychology, and philosophy of agency and of great interest to all those wishing to understand an important aspect of our moral practices.

What do mathematicians mean when they use terms such as ‘deep’, ‘elegant’, and ‘beautiful’? By applying empirical methods developed by social psychologists, we demonstrate that mathematicians' appraisals of proofs vary on four dimensions: aesthetics, intricacy, utility, and precision. We pay particular attention to mathematical beauty and show that, contrary to the classical view, beauty and simplicity are almost entirely unrelated in mathematics.

We suggest a rigorous theory of how objective single-case transition probabilities fit into our world. The theory combines indeterminism and relativity in the “branching space–times” pattern, and relies on the existing theory of causae causantes (originating causes). Its fundamental suggestion is that (at least in simple cases) the probabilities of all transitions can be computed from the basic probabilities attributed individually to their originating causes. The theory explains when and how one can reasonably infer from the probabilities of one “chance (...) set-up” to the probabilities of another such set-up that is located far away. (shrink)

Discussions about the meaning of the word “ought” are pulled in two apparently competing directions. First, in ethical theory this word is used in the paradigmatic statement of ethical principles and conclusions about what some agent is obligated to do. This leads some ethical theorists to claim that the word “ought” describes a real relation, roughly, of being obligated to (realism) or expresses some non-cognitive attitude toward agents acting in certain ways (expressivism). Second, in theoretical linguistics this word is classified (...) as a modal auxiliary verb alongside words like “might,” “may,” “can,” “must,” etc. This leads some theoretical linguists to claim that the word “ought” is a weak necessity modal, which can be modeled with universal quantification over a restricted set of possible worlds. This chapter seeks some resolution of this tension by showing how versions of realism and expressivism can be modified in light of the best semantics of “ought” as a weak necessity modal. In addition, the chapter explains how this semantics might point to a third view—inferentialism—that accounts for the meaning of “ought” not in terms of what relation it describes, nor in terms of what attitude it expresses, but rather in terms of its inferential role.

In _Camus, Philosophe: To Return to our Beginnings_ Matthew Sharpe reads Camus as a _philosophe_ in the classical and enlightenment lineages, arguing that his defense of _mesure_ singles him out amidst 20th century French thought and makes him of renewed relevance today.

Mathematical explanations are poorly understood. Although mathematicians seem to regularly suggest that some proofs are explanatory whereas others are not, none of the philosophical accounts of what such claims mean has become widely accepted. In this paper we explore Wilkenfeld’s suggestion that explanations are those sorts of things that generate understanding. By considering a basic model of human cognitive architecture, we suggest that existing accounts of mathematical explanation are all derivable consequences of Wilkenfeld’s ‘functional explanation’ proposal. We therefore argue that (...) the explanatory criteria offered by earlier accounts can all be thought of as features that make it more likely that a mathematical proof will generate understanding. On the functional account, features such as characterising properties, unification, and salience correlate with explanatoriness, but they do not define explanatoriness. (shrink)

We investigated whether mathematicians typically agree about the qualities of mathematical proofs. Between-mathematician consensus in proof appraisals is an implicit assumption of many arguments made by philosophers of mathematics, but to our knowledge the issue has not previously been empirically investigated. We asked a group of mathematicians to assess a specific proof on four dimensions, using the framework identified by Inglis and Aberdein (2015). We found widespread disagreement between our participants about the aesthetics, intricacy, precision and utility of the proof, (...) suggesting that a priori assumptions about the consistency of mathematical proof appraisals are unreasonable.

In this chapter, we consider the plausibility and consequences of the use of the term “honest errors” to describe the accidental killings of civilians resulting from the US military’s drone campaigns in Iraq, Syria, Afghanistan, and elsewhere. We argue that the narrative of “honest errors” unjustifiably excuses those involved in these killings from moral culpability, and reinforces long-standing, pernicious assumptions about the moral superiority of the US military and the inevitability of civilian deaths in combat. Furthermore, we maintain that, given (...) the knowledge-distorting practices within the US military’s organizational structure, few if any civilian deaths from drone strikes meet the criteria of a genuinely morally excusing “honest mistake”. Instead, these accidental killings often reflect objectionable attitudes of relative disregard for the safety of civilians. These attitudes are, we argue, sufficient to warrant the attribution of blame and moral responsibility, both with respect to certain individual actions and with respect to the US military as an institution. In light of this, we propose incorporating a Principle of the Moral Equality of Non-combatants into military assessments of what counts as “acceptable risk” to civilians. This would go some way, we argue, to redressing the ongoing injustice inflicted on the victims of civilian killings by the failure of the US military and US political leadership to take moral responsibility for unjustified civilian deaths.

Judith Jarvis Thomson famously argued that abortion is permissible even if we accept that a fetus qualifies as a person and possesses a right to life. The current paper presents two arguments that undermine Thomson’s position. First, the paper sketches a contractarian argument that explores Thomson’s violinist thought experiment from behind a veil of ignorance, which suggests that if we had an equal likelihood of being an unwanted fetus and a pregnant woman, it would be rational for us to oppose (...) abortion. Second, the paper discusses the hypothetical self-aborting fetus, a thought experiment that reverses the dependence relationship between a woman and a fetus. It is argued that in this scenario, where fetuses have agency of their own, Thomson’s position would counterintuitively prohibit a woman from temporarily curtailing the freedom of her fetus even to save her own life.

One’s account of the meaning of ethical sentences should fit – roughly, as part to whole – with one’s account of the meaning of sentences in general. When we ask, though, where one widely discussed account of the meaning of ethical sentences fits with more general accounts of meaning, the answer is frustratingly unclear. The account I have in mind is the sort of metaethical expressivism inspired by Ayer, Stevenson, and Hare, and defended and worked out in more detail recently (...) by Blackburn, Gibbard, and others. So, my first aim (§1) in this paper is to pose this question about expressivism’s commitments in the theory of meaning and to characterize the answer I think is most natural, given the place expressivist accounts attempt to occupy metaethics. This involves appeal to an ideationalist account of meaning. Unfortunately for the expressivist, however, this answer generates a problem; it’s my second aim (§2) to articulate this problem. Then, my third aim (§3) is to argue that this problem doesn’t extend to the sort of account of the meaning of ethical claims that I favor, which is like expressivism in rejecting a representationalist order of semantic explanation but unlike expressivism in basing an alternative order of semantic explanation on inferential role rather than expressive function.

Lewisian theism is the view that both traditional theism and Lewis’s modal realism are true. On Lewisian theism, God must exist in worlds in one of the following ways: God can be said to have a counterpart in each world; God can be said to exist in each world in the way that a universal can be said to exist in worlds, i.e. through transworld identity; God can be said to be a scattered individual, with a part of God existing (...) in each world; and, God can be said to exist in each world, through His existing from the standpoint of each world. In the literature, – have been rejected as viable options. I grant that and are not viable. However, I believe that and have been too hastily rejected. Herein, I develop ways to respond to objections to and, and conclude that is a viable option for Lewisian theists. (shrink)

One of the central debates within contemporary Anglo-American political philosophy concerns how to formulate an egalitarian theory of distributive justice which gives coherent expression to egalitarian convictions and withstands the most powerful anti-egalitarian objections. This book brings together many of the key contributions to that debate by some of the world’s leading political philosophers: Richard Arneson, G.A. Cohen, Ronald Dworkin, Thomas Nagel, Derek Parfit, John Rawls, T.M. Scanlon, and Larry Temkin.

Does artificial intelligence (AI) pose existential risks to humanity? Some critics feel this question is getting too much attention, and want to push it aside in favour of conversations about the immediate risks of AI. These critics now include the journal Nature, where a recent editorial urges us to 'stop talking about tomorrow's AI doomsday when AI poses risks today.' We argue that this is a serious failure of judgement, on Nature's part. In science, as in everyday life, we expect (...) influential actors to consider the consequences of error. As the world's leading scientific journal, Nature is certainly an influential actor, especially so in the absence of robust global regulation of AI. Yet it has manifestly failed to consider the cost of error in this case. (shrink)

This paper explains three ways to develop a conceptual role view of meaning in metaethics. First, it suggests that there’s a way to combine inspiration from noncognitivism with a particular form of the conceptual role view to form a noncognitivist view with distinctive advantages over other noncognitivist views. Second, it suggests that there’s also a way to combine a strong commitment to cognitivism with a different form of the conceptual role view to form a version of cognitivism with distinctive advantages (...) over other cognitivist views. Finally, it suggests that there's another way to think of the conceptual role view in metaethics is as opening up the space for a third way, beyond cognitivism and noncognitivism. (shrink)
