This is a major work in moral philosophy, the long-awaited follow-up to Parfit's 1984 classic Reasons and Persons, a landmark of twentieth-century philosophy. Parfit now presents a powerful new treatment of reasons and a critical examination of the most prominent systematic moral theories, leading to his own ground-breaking conclusion.

How many people should there be? Can there be overpopulation: too many people living? I shall present a puzzling argument about these questions, show how this argument can be strengthened, then sketch a possible reply.

It has long been widely agreed that some concepts can be possessed only by those who have undergone a certain type of phenomenal experience. Orthodoxy among contemporary philosophers of mind has it that these phenomenal concepts provide the key to understanding many disputes between physicalists and their opponents, and in particular offer an explanation of Mary’s predicament in the situation exploited by Frank Jackson's knowledge argument. I reject the orthodox view; I deny that there are phenomenal concepts. My arguments exploit (...) the sort of considerations that are typically used to motivate externalism about mental content. Although physicalists often appeal to phenomenal concepts to defend their view against the knowledge argument, I argue that this is a mistake. The knowledge argument depends on phenomenal concepts; if there are no phenomenal concepts, then the knowledge argument fails. (shrink)

When Ingmar and I discuss metaphysics or morality, our views are seldom far apart. Hut on the subjects of this paper, rationality and reasons, we deeply disagree.

ABSTRACT Contemporary relativists often see their view as contributing to a semantic/post-semantic account of linguistic data about disagreement and retraction. I offer an independently motivated metasemantic account of the same data, that also handles a number of cases and empirical results that are problematic for the relativist. The key idea is that the content of assertions and beliefs is determined in part by facts about other times, including times after the assertion is made or the belief is formed. On this (...) temporal externalist view, speaker behaviours such as retraction of previous assertions play a role in making it the case that a past utterance has a given meaning. (shrink)

The idea that experts (especially scientific experts) play a privileged role in determining the meanings of our words and the contents of our concepts has become commonplace since the work of Hilary Putnam, Tyler Burge, and others in the 1970s. But if experts have the power to determine what our words mean, they can do so responsibly or irresponsibly, from good motivations or bad, justly or unjustly, with good or bad effects. This paper distinguishes three families of metasemantic views based (...) on their attitudes towards bad behaviour by meaning-fixing experts, and draws a series of distinctions relevant for the normative evaluation of meaning-determining actions.

The past two decades have been a time of heightened interest in the moral aspects of the practice of medicine. This interest has been reflected in medical education by the establishment of medical humanities programs in both preclinical and clinical education in many medical schools. It has also been reflected in the literature with a dramatic increase in journal articles on medical ethics as well as the development of medical ethics in textbooks. A number of journals have developed that are (...) specifically devoted to medical ethics, including The Journal of Medical Ethics, The Journal of Medicine and Philosophy, The Journal of Medical Humanities, Theoretical Medicine, Cambridge Quarterly of Healthcare Ethics, just to name a few. The literature includes both theoretical foundations and conceptual analyses of particular issues as well as practical advice and general suggestions for how to implement programs in medical humanities.

This book investigates the impact of misinformation and the role of truth in political struggle. It develops a theory of objective truth for political controversy over topics such as racism and gender, based on the insights of intersectionality, the Black feminist theory of interlocking systems of oppression. Truth is defined using the tools of model theory and formal semantics, but the theory also captures how social power dynamics strongly influence the operation of the concept of truth within the social fabric. (...) Systemic ignorance, propagated through false speech and misinformation, sustains oppressive power structures and perpetuates systemic inequity. Truth tends to empower marginalized groups precisely because oppressive systems are maintained through systemic ignorance. If the truth sets people free, then power will work to obscure it. Hence, the rise of misinformation as a political weapon is a strategy of dominant power to undermine the political advancement of marginalized groups. (shrink)

Torin Alter (2013) attempts to rescue phenomenal concepts and the knowledge argument from the critique of Ball 2009 by appealing to conceptual mastery. I show that Alter’s appeal fails, and describe general features of conceptual mastery that suggest that no such appeal could succeed.

Byrne offers a novel interpretation of the idea that the mind is transparent to its possessor, and that one knows one’s own mind by looking out at the world. This paper argues that his attempts to extend this picture of self-knowledge force him to sacrifice the theoretical parsimony he presents as the primary virtue of his account. The paper concludes by discussing two general problems transparency accounts of self-knowledge must address.

There has been recent work on acedia and its relationship to depression, but the results are a mixed bag. In this essay, I engage some recent scholarship comparing acedia with depression, endeavouring to clarify the concept of acedia using literature from theology, philosophy, psychiatry, and even a 16th-century treatise on witchcraft. Along the way, I will show the following key theses. First, the concept of acedia is not identical to the concept of depression. Acedia is not merely a primitive psychological (...) predecessor to depression, but it marks off significantly different ways of being, not least because of one’s spiritual relation to God. As Lucrèce Luciani-Zidane (2009: 13) has said, “acedia is entangled in the heart (or life) of Christian dogma.” Second, however, it is still possible that an instance of acedia can coincide with an instance of depression, if one’s condition, or state, is such that each term can be correctly and truthfully applied. By the conclusion of this piece, I begin to explore what practical implications this view has for practitioners and laypersons. (shrink)

The purpose of this paper is to present and discuss a puzzle involving accommodation. The puzzle is based on three assumptions. The first assumption is that accommodation takes place after an utterance. The second assumption is that accommodation can make a difference to the truth-value of an utterance even if the utterance is not about the future. The third assumption is that something that takes place after an utterance cannot make a difference to the truth-value of the utterance unless the (...) utterance is about the future. Since these assumptions are jointly inconsistent, one of them must be false. The question is which one we ought to reject. The majority of the discussion is devoted to discussing each of the options, and the tentative conclusion is that the most plausible strategy is to reject the third thesis. That amounts to saying that something that takes place after an utterance can make a difference to the truth-value of the utterance even if the utterance is not about the future. (shrink)

Millians about proper names typically claim that it is knowable apriori that Hesperus is Phosphorus. We argue that they should claim instead that it is knowable only aposteriori that Hesperus is Hesperus, since the Kripke-Putnam epistemic arguments against descriptivism are special cases of Quinean arguments that nothing is knowable apriori, and Millians have no resources to resist the more general Quinean arguments.

It is widely believed that Twin-Earth-style thought experiments show that the contents of a person's thoughts fail to supervene on her intrinsic properties. Several recent philosophers have made the further claim that Twin-Earth-style thought experiments produce metaphysically necessary conditions for the possession of certain concepts. I argue that the latter view is false, and produce counterexamples to several proposed conditions. My thesis is of particular interest because it undermines some attempts to show that externalism is incompatible with privileged access.

As highly intelligent autonomous robots are gradually introduced into the home and workplace, ensuring public safety becomes extremely important. Given that such machines will learn from interactions with their environment, standard safety engineering methodologies may not be applicable. Instead, we need to ensure that the machines themselves know right from wrong; we need moral mechanisms. Morality, however, has traditionally been considered a defining characteristic, indeed the sole realm of human beings; that which separates us from animals. But if only humans (...) can be moral, can we build safe robots? If computationalism—roughly the thesis that cognition, including human cognition, is fundamentally computational—is correct, then morality cannot be restricted to human beings (since equivalent cognitive systems can be implemented in any medium). On the other hand, perhaps there is something special about our biological makeup that gives rise to morality, and so computationalism is effectively falsified. This paper examines these issues by looking at the nature of morals and the influence of biology. It concludes that moral behaviour is concerned solely with social well-being, independent of the nature of the individual agents that comprise the group. While our biological makeup is the root of our concept of morals and clearly affects human moral reasoning, there is no basis for believing that it will restrict the development of artificial moral agents. The consequences of such sophisticated artificial mechanisms living alongside natural human ones are also explored. (shrink)

In this article we examined the ways in which strategic ambiguity in the use of keywords served an enabling function within a discourse marked by conflict and ideological divisions. Our analysis focused on the intertextual relationships between five documents intended by the government to guide the development of biotechnology in New Zealand. Through our analysis we identified ‘sustainability’ as a keyword and three major roles for the deployment of the discourse strategy of strategic ambiguity in the use of this keyword. (...) First, strategic ambiguity lent an internal and intertextual coherence to the texts. Second, it allowed multiple perspectives and objectives to co-exist. Third, strategic ambiguity facilitated the participation of discourse actors who subscribed to ideologies that were more or less incommensurable. (shrink)

This article argues for a social proviso concerning capital endowments that is analogous to Locke's original proviso on access to productive natural capital.

In this essay, I muse upon aporia’s value as a pedagogical technique in the philosophy classroom using as a guide examples of aporia that are found in Plato’s Socratic dialogues. The word aporia, translated as “without passage” or “without a way,” is used metaphorically to describe the unsettling state of confusion many find themselves in after engaging in philosophical discourse. Following a brief introduction in which I situate aporia as a pedagogy amicable to experiential learning, I examine various ways in (...) which aporia appears in certain Platonic dialogues, which enables us to draw out some paradigmatic features of aporia. I then discuss how I apply aporia as a pedagogical technique in the contemporary philosophy classroom, taking up three specific concerns in detail: aporetic discomfort, right use, and potential misuse.

This chapter presents a thorough analysis of Neurath’s physicalist syntacticism. It explores connections between syntacticism and other elements of Neurath’s philosophy such as the unity of science and the sociological imperative of empiricism. It also defends the intelligibility of syntacticism. Finally, the case is made that Neurath’s fear of semantics was warranted: logical empiricism was undermined to a large extent by the widespread acceptance of semantics.

In opposing Stephen Douglas’s alleged popular right to choose a slave constitution, Abraham Lincoln developed a rudimentary conception of the normative presuppositions of democratic rights that prefigures the theory of popular sovereignty articulated by Jürgen Habermas. While Lincoln was influenced by a civic republican conception of natural rights, and referred to personal autonomy in arguing that some political choices violate the grounds of collective self-governance rights, both Lincoln—as read by Jaffa—and Habermas conceive human rights not as trans-political principles but as (...) linking moral norms with the rule of law (or coordination through political power in general). The comparison shows that Habermas’s approach to the co-originality of civil liberties and democratic rights implies that legitimate secession, revolution, and primary constituent authority must be oriented toward creation of a just legal order. This enriched linkage approach explains why the right to democracy, like the right to basic liberty, is inalienable. (shrink)

This paper develops and critiques the two-dimensionalist account of mental content developed by David Chalmers. I first explain Chalmers's account and show that it resists some popular criticisms. I then argue that the main interest of two-dimensionalism lies in its accounts of cognitive significance and of the connection between conceivability and possibility. These accounts hinge on the claim that some thoughts have a primary intension that is necessarily true. In this respect, they are Carnapian, and subject to broadly Quinean attack. (...) The remainder of the paper advances such an attack. I argue that there are possible thinkers who are willing to revise their beliefs in response to expert testimony, and that such thinkers will have no thoughts with necessary primary intensions. I even suggest that many actual humans may well be such thinkers. I go on to argue that these possible thinkers show that the two-dimensionalist accounts fail. (shrink)

Critical notice of Derk Pereboom's "Consciousness and the Prospects of Physicalism". Discusses Pereboom's idea that conscious states might be misrepresented in introspection, and his idea that instantiations of mental properties are composed of instantiations of physical properties.

I have argued that like Harry Frankfurt, Augustine implicitly distinguishes between first-order desires and higher-order volitions; yet unlike Frankfurt, Augustineheld that the liberty to form different possible volitional identifications is essential to responsibility for our character. Like Frankfurt, Augustine recognizes that we can sometimes be responsible for the desires on which we act without being able to do or desire otherwise; but for Augustine, this is true only because such responsibility for inevitable desires and actions traces (at least in part) (...) to responsibility for our volitional identifications, which in turn has leeway-libertarianconditions. However, David Hunt has interpreted Augustine’s account of divine foreknowledge as implying a type of source-incompatibilism that does not require alternative possible actions or intentions. Moreover, while Eleonore Stump’s account of Augustine on sanctification supports my interpretation, Augustine’s position on predestination in his latest writings may be incompatible with liberty of the higher-order will. I will argue against Hunt’s interpretation but admit that the leeway-libertarian has to reject the ‘no autonomy’ model in some of Augustine’s late writings. (shrink)

Victor Tadros, in this chapter, draws attention to significant overlap in our practices of providing treatment to irresponsible wrongdoers, on the one hand, and our practices of holding the responsible to account, on the other. Alternately, how little space there is between treatment and holding accountable. This should be surprising. Much of Strawson’s argument presupposes that we have implicit familiarity with the difference, and with how significant it is. We become angry with the responsible; whereas we take a more detached (...) perspective to children, the seriously impaired, or mentally ill, whom we regard as objects of treatment or management. These are supposed to represent two fundamentally distinct forms of engagement. If Tadros is right, this sense of a massive gulf in how it is appropriate to treat the responsible versus the exempt is an illusion. The actual difference is subtle. (shrink)

I criticize a case made by George Bowles for a certain theory pertaining to the evaluation of arguments on which the (degree of) attributed favourable relevance of an argument's premises to its conclusion is relevant to its evaluation, but nevertheless argue that such favourable relevance is indeed relevant to an argument's evaluation.

There are some Marxist moral philosophers who think that a distinctive and defensible ethic can be unearthed from Marx's writings. The task of unearthing it must, of course, be kept distinct from the task or elaborating and defending it. Professor Aronovitch undertakes both tasks in his paper, but he does not always succeed in keeping them apart. As a result, I believe, damage is done to the exegetical side of his project.The question of whether there is a Marxian ethic is (...) a problem both of textual interpretation and of moral philosophy. Consider, for instance, the claim that Marx has an ethic whose centrepiece is a principle of selfrealization. It is an exegetical problem to provide evidence that a principle of self-realization is to be found in Marx and to explain how he understands it. (shrink)

Drawing upon insights from virtue ethics, this essay develops a concept of collective identity specifically suited to deliberative democracy: a virtues-centered theory of deliberative justice. Viewing democratic legitimacy as a political phenomenon, we must account for more than the formal rules that must be satisfied according to deontological theories of deliberative democracy. I argue that common approaches to deliberative democracy are unable to account for the motivations of deliberation, or ensure that citizens have the cognitive skills to deliberate well. Next, (...) I engage with critics of deliberative democracy who have moved toward broader and more humanistic concepts of deliberation but have stopped short of conceiving of justice as a virtue and, in their own way, neglected questions of collective identity. I reconstruct justice as a virtue from a deliberative perspective, combining virtue ethics’ emphasis on habituation with a weaker sense of collective identity that allows for value pluralism and disagreement, consistent with deliberative democracy. That is, deliberative democracy requires a shared and habituated civic culture of mutual understanding of differences. Finally, drawing from discourse on race in contemporary American politics, I conclude with brief illustrations of the need for a collective identity based on mutual understanding. Although deliberative democracy does not require a thick or intense sense of social solidarity, it does need citizens to share habits, inclinations, and capacities to engage in communication across their differences.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Free Will’s Value: Criminal Justice, Pride, and Love by John LemosJohn DavenportLEMOS, John. Free Will’s Value: Criminal Justice, Pride, and Love. New York: Routledge, 2023. 284 pp. Cloth, $160.00It is a pleasure to read John Lemos’s latest work on moral free will, understood as the control needed for us to be morally responsible in “the just deserts sense.” Lemos is a clear writer who carefully lays out the (...) positions that he reviews and critiques. This book would be wonderful as a main text in a graduate seminar: The first six chapters critically address most of the main theories and moves in this wide field during the last twenty to twenty-five years, providing a very helpful overview while setting up Lemos’s own position. He advances an “indeterministic weightings” version of leeway-libertarianism about moral freedom that builds on both Robert Kane’s event-causal account and Robert Nozick’s older account of fixing the weight of practical considerations in the moment of choice. Lemos’s new account significantly refines the position that he defended against hard incompatiblism in his 2018 book. [End Page 721]Free Will’s Value also discusses responsibility in applied contexts, such as criminal justice and loving relationships. There are two chapters arguing that hard incompatibilists cannot save the “just deserts” aspect of criminal punishment or explain all the wrongness of taking the liberty of innocent persons mistakenly convicted. Their “public health quarantine” account of criminal justice will be utilitarian, and thus have a hard time justifying the beyond-reasonable-doubt standard for conviction. And, building on the critiques of compatibilism that he develops partly from Derk Pereboom and Bruce Waller, Lemos includes three chapters arguing that “axiological/pragmatist reasons” provide more evidence for libertarian free will than psychological evidence alone can.The final chapter in particular offers a novel argument that valuable sorts of interhuman loves need to involve self- or character-forming initiatives that are not primarily determined by factors beyond our control. The intrinsic value of some types of love, such as deep friendships—including romantic friendships—involve their being autonomous (my term), which in turn requires a kind of leeway-control. This involves arguing that “our will, effort, or a decision to love” is important to values achieved in sustaining loving relationships.Lemos’s own theory contends that Kane’s account of “self-forming actions” (SFAs) and “willings” (SFWs) in terms of dual “tryings” (or decisions) to do A or B in a fraught situation suffers from the “phenomenological problem” stated by Laura Ekstrom and Marc Balaguer, namely, that we do not normally experience fraught choices as involving such opposed tryings. This is even more evident, I believe, if we consider choices involving three or more salient options. Lemos is not convinced by Kane’s reply that the dual or multiple simultaneous efforts are usually unconscious, because he thinks responsibility for unconscious mental processes will (normally) trace to patterns of conscious choices made earlier in life. In fact, unconscious efforts, Lemos says, cannot meet even “plausible minimal compatibilist standards of responsibility” for elements of agency.I’m not convinced by this last claim, because it seems that an unconscious choice, C, could be responsive to (or counterfactually guided by) reasons relevant to C that the agent has considered in the past. Perhaps the problem is that “trying” is normally associated with attempting to act on an intention, but Kane uses it to describe the more elusive processes of agency involved in forming an intention via decision in the face of competing relevant options, which thereby incorporates motives into the intention. This sheds light on the further problem that it appears irrational to try to do multiple incompatible things at once. Pace Lemos, I think that Kane is right that “will-settling” is a special context in which it is not irrational for a single person’s agency to be engaged along dual pathways. Even if we do not call this “trying,” the agent’s interactions with the salient options are not like those of a detached spectator; they are volitional as well as evaluative.
