The paradox of rule-following that Saul Kripke finds in Wittgenstein’s Philosophical Investigations purports to show that words and thoughts have no content—that there is no intentionality. This paper refutes the paradox with a dilemma. Intentional states are posited in rational explanations, which use propositional attitudes to explain actions and thoughts. Depending on which of the two plausible views of rational explanation is right, either: the paradox is mistaken about the a priori requirements for content; or, a fatal flaw in content (...) ascription alleged by the paradox is not a flaw at all, but a necessary component of the proper method of propositional-attitude ascription. On either lemma, rational explanation defuses the paradox. (shrink)

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)

Derek Jarman’s Wittgenstein (1993) is one of the very few films made about a philosopher’s life. Almost a parody of a late twentieth-century art-house movie, it contains a mimetic performance by Karl Johnson in the title role, plus cameos by Michael Gough (Bertrand Russell) and the ubiquitous Tilda Swinton (Russell’s lover, Ottoline Morrell). There is a green Martian (played by Nabil Shaban) who quizzes the young Ludwig Wittgenstein, and a collection of handsome young men sitting on deckchairs, looking (...) puzzled and gazing adoringly at the Master. The action, such as it is, takes place against a theatrical black background with a few props, and the whole thing lasts a brisk seventy minutes... (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)

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)

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)

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)

Polysemy seems to be a relatively neglected phenomenon within philosophy of language as well as in many quarters in linguistic semantics. Not all variations in a word’s contribution to truth-conditional contents are to be thought as expressions of the phenomenon of polysemy, but it can be argued that many are. Polysemous terms are said to contribute senses or aspects to truth-conditional contents. In this paper, I will make use of the notion of aspect to argue that some apparently wild variations (...) in an utterance’s truth conditions are instead quite systematic. In particular, I will focus on Travis’ much debated green leaves case and explain it in terms of the polysemy of the noun; and in particular, in terms of the as-it-is and the as-it-looks aspects associated with kind words.

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)

Jaegwon Kim has developed an argument that interactionist dualists cannot account for the causal relations between minds and brains. This paper develops a closely related argument that focuses instead on the causal relations between minds and neurons. While there are several promising responses to Kim’s argument, their plausibility relies on a relatively simple understanding of mind–brain relations. Once we shift our focus to neurons, these responses lose their appeal. The problem is that even if mind–brain causal pairing can be explained (...) at no great theoretical cost, the complex interactions non-physical minds would need to have with neurons cannot.

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.

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)

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.

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)

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.

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)

It has recently been alleged that expressivism cannot account for the obvious fact that normative sentences and their negations express inconsistent kinds of attitudes. I explain how the expressivist can respond to this objection. I offer an account of attitudinal inconsistency that takes it to be a combination of descriptive and normative relations. The account I offer to explain these relations relies on a combination of functionalism about normative judgments and expressivism about the norms governing them. It holds that the (...) inconsistency of normative judgments is primitive. One potential problem for this view is that the large number of normative primitives that the expressivist will allegedly need to accept will render the view grossly unparsimonious. In defending this thesis, I suggest that it is a mistake to hold the lack of normative parsimony of expressivism against its core psychological claims. (shrink)

Allan Gibbard () argues that the term ‘meaning’ expresses a normative concept, primarily on the basis of arguments that parallel Moore's famous Open Question Argument. In this paper I argue that Gibbard's evidence for normativity rests on idiosyncrasies of the Open Question Argument, and that when we use related thought experiments designed to bring out unusual semantic intuitions associated with normative terms we fail to find such evidence. These thought experiments, moreover, strongly suggest there are basic requirements for a theory (...) of meaning incompatible with Gibbard's ultimate goal of providing an expressivist account of meaning-related concepts. I conclude by considering a possible way in which meaning could be normative, consistent with the intuitions about disagreement; but this form of normativism about meaning appears incompatible with Gibbard's expressivism.

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)

The paper explores the influence of greenwash on green trust and discusses the mediation roles of green consumer confusion and green perceived risk. The research object of this study focuses on Taiwanese consumers who have the purchase experience of information and electronics products in Taiwan. This research employs an empirical study by means of the structural equation modeling. The results show that greenwash is negatively related to green trust. Therefore, this study suggests that companies must reduce (...) their greenwash behaviors to enhance their consumers’ green trust. In addition, this study finds out that green consumer confusion and green perceived risk mediate the negative relationship between greenwash and green trust. The results also demonstrate that greenwash is positively associated with green consumer confusion and green perceived risk which would negatively affect green trust. It means that greenwash does not only negatively affect green trust directly but also negatively influence it via green consumer confusion and green perceived risk indirectly. Hence, if companies would like to reduce the negative relationship between greenwash and green trust, they need to decrease their consumers’ green consumer confusion and green perceived risk.

Kaplan (1989) famously claimed that monsters--operators that shift the context--do not exist in English and "could not be added to it". Several recent theorists have pointed out a range of data that seem to refute Kaplan's claim, but others (most explicitly Stalnaker 2014) have offered a principled argument that monsters are impossible. This paper interprets and resolves the dispute. Contra appearances, this is no dry, technical matter: it cuts to the heart of a deep disagreement about the fundamental structure of (...) a semantic theory. We argue that: (i) the interesting notion of a monster is not an operator that shifts some formal parameter, but rather an operator that shifts parameters that play a certain theoretical role; (ii) one cannot determine whether a given semantic theory allows monsters simply by looking at the formal semantics; (iii) theories which forbid shifting the formal "context" parameter are perfectly compatible with the existence of monsters (in the interesting sense). We explain and defend these claims by contrasting two kinds of semantic theory--Kaplan's (1989) and Lewis's (1980). (shrink)

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.

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.

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.

This article develops a view of shape representation both in visual experience and in subpersonal visual processing. The view is that, in both cases, shape is represented in a ‘layered’ manner: an object is represented as having multiple shape properties, and these properties have varying degrees of abstraction. I argue that this view is supported both by the facts about visual phenomenology and by a large collection of evidence in perceptual psychology. Such evidence is provided by studies of shape discriminability, (...) apparent motion, multiple-object tracking, and structure-from-motion. Recent neuroscientific work has also corroborated this psychophysical evidence. Finally, I draw out implications of the layered view for processes of concept acquisition. 1 Introduction2 Metric Properties andShape Properties3 Metric Views4 Against Metric Views of Visual Shape Experience5 The Visual System Uses Abstract Shape Properties6 Against Metric Views of Visual Shape Representation7 Neural Underpinnings of Abstract Shape Perception8 Implications.

When we perceive an object, we perceive the object from a perspective. As a consequence of the perspectival nature of perception, when we perceive, say, a circular coin from different angles, there is a respect in which the coin looks circular throughout, but also a respect in which the coin's appearance changes. More generally, perception of shape and size properties has both a constant aspect—an aspect that remains stable across changes in perspective—and a perspectival aspect—an aspect that changes depending on (...) one's perspective on the object. How should we account for the perspectival aspect of spatial perception? We present a framework within which to discuss the perspectival aspect of perception and put forward three desiderata that any account of the perspectival aspect of perception should satisfy. We discuss views on which the perspectival aspect of perception is analyzed in terms of constitutively mind-dependent appearance properties as well as views on which the perspectival aspect of perception is analyzed in terms of representations of mind-independent perspectival properties.

Over the course of summarizing Volume Three and Does Anything Really Matter?, I argue that Parfit does not give us strong reason to think that Naturalists, Expressivists, and Non-Realist Cognitivists agree.

A "concept" in the sense favoured by Wittgenstein is a paradigm for a transition between parts of a notational system. A concept-determining sentence such as "There is no reddish green" registers the absence of such a transition. This suggests a plausible account of what is perceived in an experiment that was first designed by Crane and Piantanida, who claim to have induced perceptions of reddish green. I shall propose a redescription of the relevant phenomena, invoking only ordinary colour (...) concepts. This redescription is not ruled out by anything the experimenters say. It accounts for certain peculiarities in both their descriptions and their subjects', and suggests that instead of discovering forbidden colours the experimenters introduced a new use of "-ish". Still, there is a point in speaking of "reddish green" in their context, which can be motivated by invoking what Wittgenstein calls a "physiognomy". (shrink)

In this paper, I propose that those who reject higher-order theories of consciousness should not rule out the possibility of having conscious experiences that they cannot introspect. I begin by offering four arguments that such non-introspectible conscious experiences are possible. Next, I offer two arguments for thinking that we actually have such experiences. According to the first argument, it is unlikely that evolution would have furnished us with a faculty of introspection that worked flawlessly. According to the second argument, there (...) are many plausible potential sources of non-introspectible experiences. Given that all of these sources are at least somewhat plausible, it is fairly probable that we have some kind or other. Finally, I consider whether we might be justified in believing that we can introspect all of our conscious experiences if in fact we can. I show that current approaches to justifying belief in epiphenomenal qualia do not carry over. The upshot of these arguments is that we should be less certain that we really know what it feels like to be us. There may be much more to our experiences than we are aware of. (shrink)

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)

This paper argues that, with certain provisos, predicting one's future actions is incompatible with rationally deliberating about whether to perform those actions. It follows that fully rational omniscient agents are impossible, since an omniscient being could never rationally deliberate about what to do . Consequently, theories that explain practical reasons in terms of the choices of a perfectly rational omniscient agent must fail. The paper considers several ways of defending the possibility of an omniscient agent, and concludes that while some (...) of these may work, they are inconsistent with the aim of explaining practical normativity by appeal to such an agent.

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).

As Hume remarks, the view that aesthetic evaluations are ‘subjective’ is part of common sense—one certainly meets it often enough in conversation. As philosophers, we can distinguish the one sense of the claim (‘aesthetic evaluations are mind- dependent’) from another (‘aesthetic evaluations are relative’). A plausible reading of the former claim (‘some of the grounds of some aesthetic evaluations are response- dependent’) is true. This paper concerns the latter claim. It is not unknown, or even unexpected, to find people who (...) believe that aesthetic evaluations are culturally relative, or even agent-relative. A cultural relativist would hold that there is no way to adjudicate an apparent disagreement between, say, a Japanese critic who finds Wright of Derby clunky and unsubtle, and a British critic who finds Utamaro’s flower pictures overly pretty and sentimental.

This essay ties together some main strands of the author’s research spanning the last quarter-century. Because of its broad scope and space limitations, he prescinds from detailed arguments and instead intuitively motivates the general points which are supported more fully in other publications to which he provides references. After an initial delineation of several distinct notions of meaning, the author considers such a notion deriving from the evolutionary biology of communication that he terms ‘organic meaning’, and places it in the (...) context of evolutionary game theory. That provides a framework for a special type of organic meaning found in the phenomenon of expression, of which the author here offers an updated characterization while highlighting its wide philosophical interest. Expression in turn generalizes to a paradigmatic form of human communication—conversation—and section 4 provides a taxonomy of conversation-types while arguing that attention to such types helps to sharpen predictions of what speakers say rather than conversationally implicate. We close with a view of fictional discourse on which authors of fictional works are engaged in conversation with their readers, and can provide them with knowledge in spite of the fictional character of their conversation. Such knowledge includes knowledge of how an emotion feels and is thus a route to empathy. (shrink)

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.

Many claims about conceptual matters are often represented as, or inferred from, claims about the meaning, reference, or mastery, of words. But sometimes this has led to treating conceptual analysis as though it were nothing but linguistic analysis. We canvass the most promising justifications for moving from linguistic premises to substantive conclusions. We show that these justifications fail and argue against current practice (in metaethics and elsewhere), which confuses an investigation of a word’s meaning, reference, or competence conditions with an (...) analysis of some concept or property associated with that word.

ABSTRACT. Associationist psychologists of the late 19th-century premised their research on a fundamentally Humean picture of the mind. So the very idea of mental science was called into question when T. H. Green, a founder of British idealism, wrote an influential attack on Hume’s Treatise. I first analyze Green’s interpretation and criticism of Hume, situating his reading with respect to more recent Hume scholarship. I focus on Green’s argument that Hume cannot consistently admit real ideas of spatial (...) relations. I then argue that William James’s early work on spatial perception attempted to vindicate the new science of mind by showing how to avoid the problems Green had exposed in Hume’s empiricism. James’s solution involved rejecting a basic Humean assumption—that perceptual experience is fundamentally composed of so-called minima sensibilia, or psychological atoms. The claim that there are no psychological atoms is interesting because James supported it with experimental data rather than (as commentators typically suppose) with introspective description or a priori argument. James claimed to be the real descendant of British empiricism on grounds that his anti-atomistic model of perception fortified what Green had perhaps most wanted to demolish—the prospect of using empirical, scientific methods in the study of mind.

In this paper I briefly set out Susan Moller Okin’s liberal feminist position and then rehearse a number of criticisms of Okin which together suggest that dismantling the gender system and adopting the principle of androgyny would not be compatible with liberalism. This incompatibility appears to vindicate an extreme feminist critique of liberalism. I argue that nevertheless a liberal feminism is possible. The liberal feminist ought to adopt the principle of parity, that is, guaranteed equal representation of both sexes in (...) parliament, rather than the requirement of androgyny. Parity follows from a conception of procedural justice, for it provides a mechanism which guarantees that the interests of both sexes are fairly represented in the legislature. Parity may also go some way to alleviating the tensions which exist between feminism and multiculturalism. (shrink)

Despite numerous and increasing attempts to define what life is, there is no consensus on necessary and sufficient conditions for life. Accordingly, some scholars have questioned the value of definitions of life and encouraged scientists and philosophers alike to discard the project. As an alternative to this pessimistic conclusion, we argue that critically rethinking the nature and uses of definitions can provide new insights into the epistemic roles of definitions of life for different research practices. This paper examines the possible (...) contributions of definitions of life in scientific domains where such definitions are used most (e.g., Synthetic Biology, Origins of Life, Alife, and Astrobiology). Rather than as classificatory tools for demarcation of natural kinds, we highlight the pragmatic utility of what we call operational definitions that serve as theoretical and epistemic tools in scientific practice. In particular, we examine contexts where definitions integrate criteria for life into theoretical models that involve or enable observable operations. We show how these definitions of life play important roles in influencing research agendas and evaluating results, and we argue that to discard the project of defining life is neither sufficiently motivated, nor possible without dismissing important theoretical and practical research.

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.

Given the ascribed antinaturalist theory of judgment, Green’s Nietzsche cannot stop with the error theory. “Kant and Spir argue that the only way an objectively valid judgment about an object is possible is if the qualities attributed to the object are unconditionally united in the mind, that is, united in an atemporal and necessary manner”. Thoughts, and the subjects that have them, must be timeless. There must also be a “necessary connection between thought and its object”. Reality, on the (...) other hand, isn’t timeless: there is change, or becoming—this is Nietzsche’s naturalism. Thus, the connection between thoughts and reality fails, there is no timeless subject to have thoughts, and so: “We do not think”. It follows that there are no thoughts to be false—no error theory—and naturalism itself “cannot be thought”. Green calls this Nietzsche’s “noncognitivism” and concludes that the contradictions between Nietzsche’s naturalism, error theory, and noncognitivism mean that he “did not have one considered epistemological position” —a rather mild way of putting it.

How is the burden of proof to be distributed among individuals who are involved in resolving a particular issue? Under what conditions should the burden of proof be distributed unevenly? We distinguish attitudinal from dialectical burdens and argue that these questions should be answered differently, depending on which is in play. One has an attitudinal burden with respect to some proposition when one is required to possess sufficient evidence for it. One has a dialectical burden with respect to some proposition (...) when one is required to provide supporting arguments for it as part of a deliberative process. We show that the attitudinal burden with respect to certain propositions is unevenly distributed in some deliberative contexts, but in all of these contexts, establishing the degree of support for the proposition is merely a means to some other deliberative end, such as action guidance, or persuasion. By contrast, uneven distributions of the dialectical burden regularly further the aims of deliberation, even in contexts where the quest for truth is the sole deliberative aim, rather than merely a means to some different deliberative end. We argue that our distinction between these two burdens resolves puzzles about unevenness that have been raised in the literature. (shrink)

Recently many methods for reducing the risk of human extinction have been suggested, including building refuges underground and in space. Here we will discuss the perspective of using military nuclear submarines or their derivatives to ensure the survival of a small portion of humanity who will be able to rebuild human civilization after a large catastrophe. We will show that it is a very cost-effective way to build refuges, and viable solutions exist for various budgets and timeframes. Nuclear submarines are (...) surface independent, and could provide energy, oxygen, fresh water and perhaps even food for their inhabitants for years. They are able to withstand close nuclear explosions and radiation. They are able to maintain isolation from biological attacks and most known weapons. They already exist and need only small adaptation to be used as refuges. But building refuges is only “Plan B” of existential risk preparation; it is better to eliminate such risks than try to survive them. (shrink)
