Ian Stoner has recently argued that we ought not to colonize Mars because doing so would flout our pro tanto obligation not to violate the principle of scientific conservation, and there is no countervailing considerations that render our violation of the principle permissible. While I remain agnostic on, my primary goal in this article is to challenge : there are countervailing considerations that render our violation of the principle permissible. As such, Stoner has failed to establish that we ought not (...) to colonize Mars. I close with some thoughts on what it would take to show that we do have an obligation to colonize Mars and related issues concerning the relationship between the way we discount our preferences over time and projects with long time horizons, like space colonization.

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.

Mark Schroeder has argued that all reasonable forms of inconsistency of attitude consist of having the same attitude type towards a pair of inconsistent contents (A-type inconsistency). We suggest that he is mistaken in this, offering a number of intuitive examples of pairs of distinct attitudes types with consistent contents which are intuitively inconsistent (B-type inconsistency). We further argue that, despite the virtues of Schroeder's elegant A-type expressivist semantics, B-type inconsistency is in many ways the more natural choice in developing (...) an expressivist account of moral discourse. We close by showing how to adapt ordinary formality-based accounts of logicality to define a B-type account of logical inconsistency and distinguish it from both semantic and pragmatic inconsistency. In sum, we provide a roadmap of how to develop a successful B-type expressivism. (shrink)

Modern aesthetics is divided into two branches – the Anglo-American and the Continental. A major cause of this division is their divergent views about the place of history in aesthetics, the first tending to minimize historical considerations, while the second readily embraces them. This article explores the place of history in André Malraux's theory of art and argues that his thinking quickly resolves this long-standing disagreement. (This text is a translation of the published French version.).

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)

Pitt :735–741, 2017) has argued that reductive representationalism entails an absurdity akin to the “paramechanical hypothesis” Ryle attributed to Descartes. This paper focuses on one version of reductive representationalism: the property-complex theory. We contend that at least insofar as the property-complex theory goes, Pitt is wrong. The result is not just a response to Pitt, but also a clarification of the aims and structure of the property-complex theory.

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.

Is there one univocal or generic notion of ground? Monists answer yes, while pluralists answer no. Pluralists argue that monism cannot meet plausible constraints on an adequate theory of ground. My aim in this paper is to articulate a monist theory of ground that can satisfy the pluralist constraints in a way that leaves the pluralists with no reasons not to endorse the monist picture of ground. I do this by adopting a tripartite conception of ground and then showing that (...) it has the resources to vindicate monism while satisfying the pluralist constraints on a theory of ground.

That Descartes’ God is not a deceiver is amongst the canonical claims of early modern philosophy. The significance of this (purported) fact to the coherence of Descartes’ system is likewise canonical, infused in how we teach and think about the _Meditations_. Though prevalent, both ends of this narrative are suspect. We argue that Descartes’ color eliminativism, when coupled with his analysis of the cognitive structure of our sensory systems, entails that God is a deceiver. It’s doubtful that Descartes recognized this, (...) given his insistence that God is not a deceiver, and the role this plays in his system. But this is a concession Descartes can grant if we are careful about the kind of deception at play—a kind Descartes _does_ recognize, albeit not without some ambiguity. On our story, Descartes’ metaphysics and epistemology are not driven by concerns about deception _per se_, but by concerns about God’s _benevolence_. (shrink)

There are many different oughts. There is a moral ought, a prudential ought, an epistemic ought, the legal ought, the ought of etiquette, and so on. These oughts can prescribe incompatible actions. What I morally ought to do may be different from what I self-interestedly ought to do. Philosophers have claimed that these conflicts are resolved by an authoritative ought, or by facts about what one ought to do simpliciter or all-things-considered. However, the only coherent notion of an ought simpliciter (...) has preposterous first-order normative commitments. It is more reasonable to reject the ought simpliciter in favor of the form of normative pluralism advocated in (Tiffany 2007). (shrink)

Are there cases in which agents ought to give up on satisfying an obligation, so that they can avoid a temptation which will lead them to freely commit an even more significant wrong? Actualists say yes. Possibilists say no. Both positions have absurd consequences. This paper argues that common-sense morality is committed to an inconsistent triad of principles. This inconsistency becomes acute when we consider the cases that motivate the possibilism–actualism debate. Thus, the absurd consequences of both solutions are unsurprising: (...) any proposed solution will have consequences incompatible with common moral practice. Arguments for denying one of the principles are considered and rejected. The paper then suggests that the inconsistent moral commitments originate in an inconsistent picture of human agency. Revisionary pictures of human agency are considered. It is argued that a quasi-Platonic picture of agency, similar to that advocated by Gary Watson 1977, is the most promising. (shrink)

Mark Schroeder’s expressivist program has made substantial progress in providing a compositional semantics for normative terms. This paper argues that it risks achieving this semantic progress at the cost of abandoning a key theoretical motivation for embracing expressivism in the first place. The problem can be summarized as a dilemma. Either Schroeder must allow that there are cases in which agents are in disagreement with one another, or can make valid inferences, but that these disagreements or inferences are not expressible (...) in natural language; or his version of expressivism must abandon one of the key theoretical advantages expressivist theories seemed to possess over cognitivism, the ability to provide a very straightforward explanation of the action- and attitude-guiding role of normative judgments.

Early discussions of ?climate justice? have been dominated by economists rather than political philosophers. More recently, analytical liberal political philosophers have joined the debate. However, the philosophical discussion of climate justice remains in its early stages. This paper considers one promising approach based on human rights, which has been advocated recently by several theorists, including Simon Caney, Henry Shue and Tim Hayward. A basic argument supporting the claim that anthropogenic climate change violates human rights is presented. Four objections to this (...) argument are examined: the ?future persons? objection; the ?risk? objection; the ?collective causation? objection; and the ?demandingness? objection. This critical examination leads to a more detailed specification and defence of the claim that anthropogenic climate change violates human rights. (shrink)

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)

Thomas Reid (1710–96) is increasingly being seen as a highly significant philosopher and a central figure in the Scottish Enlightenment. This new edition of Reid's classic philosophical text in the philosophy of mind at long last gives scholars a complete, critically edited text of the Inquiry. The critical text is based on the fourth life-time edition (1785). A selection of related documents showing the development of Reid's thought, textual notes, bibliographical details of previous editions and a full introduction by the (...) editor makes this an important contribution to the study of this increasingly respected philosopher. -/- Key Features - Complete, critically edited text of the Inquiry accompanied by a judicious selection of manuscript evidence relating to its composition - Comprehensive Introduction providing an historical and philosophical account of the formation of the Inquiry - Detailed textual notes which include bibliographical details and allusions, translations, references to secondary literature and selected passages from Reid's manuscripts.

Ambivalence is most naturally characterized as a case of conflicting desires. In most cases, an agent’s intrinsic desires conflict contingently: there is some possible world in which both desires would be satisfied. This paper argues, though, that there are cases in which intrinsic desires necessarily conflict—i.e., the desires are not jointly satisfiable in any possible world. Desiring a challenge for its own sake is a paradigm case of such a desire. Ambivalence of this sort in an agent’s desires creates special (...) problems for the project of reducing all facts about an agent’s desires to facts about his or her preferences over options. If this reductive project fails, there is reason to suspect that the Decision Theory cannot give us a complete theory of Humean rationality. (shrink)

John Smith (1618-1652), long known for the elegance of his prose and the breadth of his erudition, has been underappreciated as a philosophical theologian. This book redresses this by showing how the spiritual senses became an essential tool for responding to early modern developments in philosophy, science, and religion for Smith. Through a close reading of the Select Discourses (1660) it is shown how Smith’s theories of theological knowledge, method, and prophecy as well as his prescriptive account of Christian piety (...) rely on his spiritual aesthetics. Smith offers a coherent system with intellectual intuition informing natural theology and revelation supplemented by spiritual perception via the imagination too. The central uniting feature of Smith’s philosophical theology is thus ‘spiritual sensation’ broadly construed. The book closes with proposals for research on Smith’s influence on the accounts of the spiritual senses developed by significant later figures including Jonathan Edwards (1703-1758) and John Wesley (1703-1791).

Mengzi states that our human nature consists of our ability to feel compassion, disdain, respect, and (dis-)approval: all human beings have them. But he also states that we lose these four emotional capacities if we don’t reflect on or attend to them. There is an apparent contradiction in saying that all humans have them, but some have lost them. This essay offers a close reading of Mengzi’s phrase “to lose it” that helps explain away this appearance of contradiction. In doing (...) so, Mengzi is interpreted to be offering an ethics of attention about how we should attend to ourselves and others selectively to have a functional social life. (shrink)

Hybridization by introgression (“hybridization”) is a complex topic in conservation. Many conservation decision-makers are concerned about hybridization by introgression because it may threaten species persistence or local phenotypes, among other potential long-term problems. While attitudes have changed towards hybridization as a conservation threat, there are still concerns about hybridization as a problem, particularly if the hybridization was anthropogenically mediated. I propose that these concerns are overblown and that it is misguided to focus on whether hybridization is unintentionally human-mediated. I argue (...) that practitioners should still consider the effects of hybridization on conservation, but the reasons should concern the long-term environmental consequences, such as ecological function and social and cultural that hybridization has, rather than whether humans “caused” the hybrid. I propose a series of steps to think differently about these cases. (shrink)

Experiences, by definition, have phenomenal character. But many experiences have a specific type of phenomenal character: presentational character. While both visual experience and conscious thought make us aware of their objects, only in visual experience do objects seem present before the mind and available for direct access. I argue that Higher-Order Thought (HOT) theories of consciousness have a particularly steep hill to climb in accommodating presentational character.

A number of philosophers have offered quasi-perceptual theories of desire, according to which to desire something is roughly to “see” it as having value or providing reasons. These are offered as alternatives to the more traditional Humean Theory of Motivation, which denies that desires have a representational aspect. This paper examines the various considerations offered by advocates to motivate quasi-perceptualism. It argues that Humeanism is in fact able to explain the same data that the quasi-perceptualist can explain, and in one (...) case the Humean explanation is superior. Quasi-perceptual accounts of desire, the paper concludes, are for the most part unmotivated. (shrink)

I examine two explanatory models of choking: the representationalist model and the anti-representationalist model. The representationalist model is based largely on Anderson's ACT model of procedural knowledge and is developed by Masters, Beilock and Carr. The antirepresentationalist model is based on dynamical models of cognition and embodied action and is developed by Dreyfus who employs an antirepresentational view of know-how. I identify the models' similarities and differences. I then suggest that Dreyfus is wrong to believe representational activity requires reflection and (...) attention. I also argue that the representationalist model of choking is preferable, since some embodied actions require appeals to representations, something not available to Dreyfus's anti-representational model.

I defend the thesis that most or all perceptual experiences are infused with imaginative contributions. While the idea is not new, it has few supporters. I begin by developing a framework for the underlying debate. Central to that framework is the claim that a perceptual experience is infused with imagination if and only if there are self-generated contributions to that experience that have ampliative effect on its phenomenal and directed elements. Self-generated ingredients to experience are produced by the subject as (...) opposed to being received from the world. Some form of stored content is an obvious starting point. Ampliative effects are aspects of perceptual experience that outstrip the content the senses get from the world. This conceptual framework is applied to three case studies: object-sameness and object-kind recognition (section 2), memory colour (section 3), and perceptual constancy and amodal completion (section 4). If the three cases and my overall analysis are accepted (a substantive if), then we have a forceful inductive argument for perception being infused with imagination. (shrink)

Appealing to imagination for modal justification is very common. But not everyone thinks that all imaginings provide modal justification. Recently, Gregory and Kung :620–663, 2010) have independently argued that, whereas imaginings with sensory imageries can justify modal beliefs, those without sensory imageries don’t because of such imaginings’ extreme liberty. In this essay, I defend the general modal epistemological relevance of imagining. I argue, first, that when the objections that target the liberal nature of non-sensory imaginings are adequately developed, those objections (...) also threaten the sensory imaginings. So, if we think that non-sensory imaginings are too liberal for modal justification, we should say the same about sensory imaginings. I’ll finish my defense by showing that, when it comes to deciding between saying that all imaginings are prima facie justificatory and saying that no imaginings are justificatory, there is an independent reason for accepting the former.

This paper discusses varieties of normative phenomena, ranging from morality, to epistemic justification, to the rules of chess. It canvases a number of distinctions among these different normative phenomena. The most significant distinction is between formal and authoritative normativity. The prior is the normativity exhibited by any standard one can meet or fail to meet. The latter is the sort of normativity associated with phenomena like the "all-things-considered" ought. The paper ends with a brief discussion of reasons for skepticism about (...) authoritative normativity. (shrink)

Many authors have proposed that grounding is closely related to metaphysical laws. However, we argue that no existing theory of metaphysical laws is sufficiently general. In this paper we develop a general theory of grounding laws, proposing that they are generative relations between pluralities of propositions and propositions. We develop the account in an essentialist language; this allows us to state precisely the sense in which grounding might be reduced to laws. We then put the theory to use in showing (...) how moral laws can play a role in grounding particular moral facts, in defending monism about ground, and in showing in what sense there is no gap between the grounds and the grounded. Finally, we make a novel proposal about what grounds facts about ground. (shrink)

Joseph Raz and Sergio Tenenbaum argue that the Guise of the Good thesis explains both the possibility of practical reason and its unity with theoretical reason, something Humean psychological theories may be unable to do. This paper will argue, however, that Raz and Tenenbaum face a dilemma: either the version of the Guise of the Good they offer is too strong to allow for weakness of will, or it will lose its theoretical advantage in preserving the unity of reason.

For Malraux, modernity in art is not only about modern art; it is also about the birth of what he aptly terms “the first universal world of art.” This event was a consequence of the process of metamorphosis which is central to Malraux’s account of the relationship between art and time. The article explains this event, noting also that modern aesthetics has not provided an explanation. (This is the English version of the final which will be in French.).

Normative discourse frequently involves explanation. For example, we tell children that hitting is wrong because it hurts people. In a recent paper, Selim Berker argues that to account for this kind of explanation, expressivists need an account of normative grounding. Against this, I argue that expressivists should eschew grounding and stick to a more pragmatic picture of explanation, one that focuses on how we use explanatory speech acts to communicate information. I propose that the standard form of a normative explanation (...) is a generalizing explanation, one which shows a particular moral injunction to follow from a more general injunction. I use Marc Lange’s account of unifying explanations in mathematics as a model for the canonical form of a normative explanation, but also to establish that logical entailment can be explanatory, so long as premises entailing the conclusion answer appropriately to our interests. An additional upshot of the resulting view is that it paves the way for a purely metaphysical solution to the problem of creeping minimalism. Quasireal properties are those that, unlike real properties, stand outside of the metaphysical hierarchy of grounding relations. (shrink)

In earlier work, I predicted that we would probably not be able to determine the colors of the dinosaurs. I lost this epistemic bet against science in dramatic fashion when scientists discovered that it is possible to draw inferences about dinosaur coloration based on the microstructure of fossil feathers (Vinther et al., 2008). This paper is an exercise in philosophical error analysis. I examine this episode with two questions in mind. First, does this case lend any support to epistemic optimism (...) about historical science? Second, under what conditions is it rational to make predictions about what questions scientists will or will not be able answer? In reply to the first question, I argue that the recent work on the colors of the dinosaurs matters less to the debate about the epistemology of historical science than it might seem. In reply to the second question, I argue that it is difficult to specify a policy that would rule out the failed bet without also being too conservative. (shrink)

We offer an account of the metaphysics of persons rooted in Latter-day saint scripture that vindicates the essentiality of origins. We then give theological support for the claim that prospects for the success of God’s soul making project are bound up in God creating particular persons. We observe that these persons would not have existed were it not for the occurrence of a variety of evils (of even the worst kinds), and we conclude that Latter-day saint theology has the resources (...) to endorse a strong soul-making non-identity theodicy. We then introduce two complications for this account rooted in the problem of horrendous evils. First, horrendous evils threaten to undermine our confidence that God is good to each created person within the context of their life. And second, horrendous evils raise concerns about the value of persons whose existence depends on the occurrence of those evils. We may wonder whether those whose existence depends on the occurrence of horrendous evils are valuable enough to motivate God’s allowance of those evils. We show that by attending to important structural features of a post-mortem, pre-eschatological state called the spirit world, Latter-day Saints can ameliorate these concerns about horrendous evils .

Mental content normativists hold that the mind’s conceptual contents are essentially normative. Many hold the view because they think that facts of the form “subject S possesses concept c” imply that S is enjoined by rules concerning the application of c in theoretical judgments. Some opponents independently raise an intuitive objection: even if there are such rules, S’s possession of the concept is not the source of the enjoinment. Hence, these rules do not support mental content normativism. Call this the (...) “Source Objection.” This paper refutes the Source Objection, outlining a key strand of the relationship between judgments and their contents in the process. Theoretical judgment and mental conceptual content are equally the source of enjoinment; norms for judging with contents do not derive from one at the expense of the other. (shrink)

Can novels, plays and poetry tell us something important and true about who we are, about others, and about life generally? The question seems to be of interest not only to writers on literary theory and aesthetics, but to people generally. This paper considers the issues involved.

Attitudinal embeddings, such as ‘I hope that murder is wrong’ or ‘she is glad that eating meat is not wrong’ are a less substantial problem for expressivists than is standardly thought. If expressivists are entitled to talk of normative beliefs, they can explain what it is to for an attitude to be semantically related to a normative content in terms of being functionally related to a belief with a normative content.

Deliberation often begins with the question ‘What do I want to do?’ rather than the question of what one ought to do. This paper takes that question at face value, as a question about which of one’s desires is strongest, which sometimes guides action. The paper aims to explain which properties of a desire make that desire strong, in the sense of ‘strength’ relevant to this deliberative question. Both motivational force and phenomenological intensity seem relevant to a desire’s strength; however, (...) accounting for the strength of a desire in these terms opens up significant indeterminacy about what we want. The paper argues that this indeterminacy is often resolved simply by posing the question ‘What do I want to do?’ to oneself: there is reason to believe that one’s answer will play a verdictive role, partially determining what the agent most wants. Self-reflective beliefs can play a self-fulfilling role, and surprisingly this seems to follow from basic platitudes about the belief-desire model. (shrink)

A conference paper examining the relationship between art and what is loosely termed the “real world”.

Venomous snakebite is a neglected tropical disease and disease of poverty, affecting hundreds of thousands of people annually. The only effective medical intervention for snakebite is antivenom, produced primarily using captive venomous snakes as a source of venom. This paper analyzes snakes’ welfare at venom labs within this global health context. I recommend significant changes to improve the welfare of captive snakes, particularly in light of recent ethological research and attention on snakes. These recommendations are broadly consequentialist, aiming to improve (...) the lives of the snakes and ensure that people have increased access to affordable antivenom. (shrink)

The goal of this project is to encourage biologists to exclude any mention of 'copying errors' from the latest definition of the theory of evolution. Instead, it should be accepted that evolutionary change is facilitated by an evolved system of variety-maintenance and variety-generation which in turn leads to novel structures and complexity.

I argue that standard explanationist solutions to the problem of creeping minimalism are largely on the right track, but they fail to correctly specify the kind of explanation that is relevant to distinguishing realism from quasirealism. Quasirealism should not be distinguished from realism in terms of the explanations it gives of why a normative judgment—a normative sentence or attitude—has the semantic content that it has. Rather, it should be distinguished in terms of the explanations it offers of what the semantic (...) content of a normative judgment is. (shrink)

This chapter defends a view of semantics on which developing a semantic theory closely resembles developing a scale of measurement. The view helps explain how semantics has made so much progress despite deep disagreements about the target of semantic theorizing (e.g., between those who maintain that semantics is characterizing something psychological, and those who maintain that it is characterizing something social), how appeals to set-theoretic abstracta make sense despite Benacerraf-style worries and despite the fact that set-theoretic entities fit badly with (...) standard (e.g., causal) metasemantic views, and why the threat of radical context sensitivity does not undermine the semantic project.

By creating certain marks on paper, or by making certain sounds-breathing past a moving tongue-or by articulation of hands and bodies, language users can give expression to their mental lives. With language we command, assert, query, emote, insult, and inspire. Language has meaning. This fact can be quite mystifying, yet a science of linguistic meaning-semantics-has emerged at the intersection of a variety of disciplines: philosophy, linguistics, computer science, and psychology. Semantics is the study of meaning. But what exactly is "meaning"? (...) What is the exact target of semantic theory? Much of the early work in natural language semantics was accompanied by extensive reflection on the aims of semantic theory, and the form a theory must take to meet those aims. But this meta-theoretical reflection has not kept pace with recent theoretical innovations. This volume re-addresses these questions concerning the foundations of natural language semantics in light of the current state-of-the-art in semantic theorising. (shrink)

Non-cognitivists are known to face a problem in extending their account of straightforward predicative moral judgments to logically complex moral judgments. This paper presents a related problem concerning how non-cognitivists might extend their accounts of moral judgments to other kinds of moral attitudes, such as moral hopes and moral intuitions. Non-cognitivists must solve three separate challenges: they must explain the natures of these other attitudes, they must explain why they count as moral attitudes, and they must explain why the moral (...) attitudes are systematically correlated with ordinary propositional attitudes. After presenting the problem, this paper examines several contemporary theories with some initial promise for solving it, and argues that they are insufficient. (shrink)

Derek Hough's simple thesis is that neo-Darwinism is incorrect and that there is a much better version of the theory of evolution; one which Darwin himself would have actually believed.

In this paper, I argue that forgiveness is a morally appropriate response only when it is grounded in the wrongdoer’s demonstration of genuine remorse, their offer of a sincere apology, and, where appropriate, acts of recompense and behavioral change. I then respond to John Kleinig’s suggestion (in his paper “Forgiveness and Unconditionality”) that when an apology is not forthcoming, there are at least three additional grounds that, when motivated by virtues such as love and compassion, could nevertheless render “unconditional forgiveness” (...) a morally laudable option. I argue that such grounds could indeed constitute or result in laudable responses to wrongdoing, but only if they are not conceived of or described in terms of forgiveness. (shrink)

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)
