Epistemological disjunctivism, as defended by, for example, McDowell, Neta and Pritchard, is the view that epistemic justification can be – and in paradigmatic cases of perceptual knowledge actually is – both factive and reflectively accessible. One major problem for this view is the access problem: apparently, epistemological disjunctivism entails that ordinary external world propositions can be known by reflection alone. According to epistemological disjunctivism, seeing that the sun is shining is reflectively accessible and seeing that the sun is shining entails (...) that it is. Assuming closure of reflective knowledge under known entailment it is also reflectively knowable that the sun is shining. Drawing on joint work with Neta, Pritchard replies that disjunctivism is not committed to this absurdity, but only to the possibility of reflective access to empirical reasons. In this article I offer an interpretation of this reply, but also an objection to it: my interpretation is based on applying the source/content distinction to epistemic reasons. My objection is based on arguing that the access problem is a problem for any version of access internalism. Although Pritchard's reply solves the general access problem, it does not solve the access problem that is generated by the specific commitments of epistemological disjunctivism. Due to the transparency of self-knowledge of propositional perception, epistemological disjunctivism cannot meet a central requirement for applying the source/content distinction. (shrink)

Putnam's argument that we are not brains in a VAT has recently seen a resurgence in interest. Although objections to it are legion, an emerging consensus seems to be that even if it successfully refutes one version of the brain in a VAT scenario, lifelong envatment, it is powerless against a different one, recent envatment. Although initially appealing, I argue in this paper that this response-merely replacing lifelong envatment by recent envatment-is a bad response to Putnam's argument. Yet there is (...) a different version of the brain in a VAT scenario, recent memory-altering envatment, that Putnam's argument does not refute and is also sufficiently radical. The crucial issue turns out to be which epistemic sources sceptical scenarios may attack. I argue that there's no convincing reason for exempting memory from the sceptical attack: Sceptical scenarios must target memory to be sufficiently radical and they can do so without violating any constraint on sceptical scenarios. In the end Putnam's argument doesn't fail because of some 'deep' philosophical mistake, but because it overlooks how flexible and adjustable sceptical scenarios are. (shrink)

On a common view of scenario-based sceptical arguments sceptical scenarios are error-possibilities, i.e. their point is to introduce the possibility of having only false beliefs. However, global error is impossible for purely logical/conceptual reasons: Even if one’s beliefs are consistent, the negations of one’s beliefs need not be consistent as well. My paper deals with the question of what the consequences of this result are. Two attempts at repairing scenario-based sceptical arguments within the framework of understanding sceptical scenarios as error-possibilities (...) are found wanting. Instead, what should be given up is the assumption that sceptical scenarios are error-possibilities. What is thought-provoking about the scenario of the brain in a vat is not that none of its empirical beliefs are true, but that all of its empirical beliefs fall short of knowledge at the same time. Hence, sceptical scenarios are not error-possibilities, but ignorance possibilities. If this is so, both the closure argument and the underdetermination argument commit a subtle mistake and should be replaced by slightly different arguments. The principle of excluded ignorance-possibilities turns out to be an epistemological principle that is faithful to scepticism’s tenets without misinterpreting sceptical scenarios as error-possibilities.

The relation of scepticism to infallibilism and fallibilism is a contested issue. In this paper I argue that Cartesian sceptical arguments, i.e. sceptical arguments resting on sceptical scenarios, are neither tied to infallibilism nor collapse into fallibilism. I interpret the distinction between scepticism and fallibilism as a scope distinction. According to fallibilism, each belief could be false, but according to scepticism all beliefs could be false at the same time. However, to put this distinction to work sceptical scenarios have to (...) be understood as ignorance-possibilities, not as error-possibilities. To show that scepticism is not tied to infallibilism I reject the principle of unrestricted relevance according to which any error- or ignorance-possibility whatsoever is relevant. Instead I argue that the sceptic should distinguish between local and global ignorance-possibilities. Global ignorance-possibilities are relevant even though not all ignorance-possibilities are relevant. The result is a refined version of the Cartesian sceptical argument that avoids two traps other versions do not avoid. (shrink)

One of the unconventional features of Wittgenstein’s _Tractatus Logico-Philosophicus_ is its use of an elaborated and detailed numbering system. Recently, Bazzocchi, Hacker und Kuusela have argued that the numbering system means that the _Tractatus_ must be read and interpreted not as a sequentially ordered book, but as a text with a two-dimensional, tree-like structure. Apart from being able to explain how the _Tractatus_ was composed, the tree reading allegedly solves exegetical issues both on the local and the global level. This (...) paper defends the sequential reading against the tree reading. After presenting the challenges generated by the numbering system and the two accounts as attempts to solve them, it is argued that Wittgenstein’s own explanation of the numbering system, anaphoric references within the _Tractatus_ and the exegetical issues mentioned above do not favour the tree reading, but a version of the sequential reading. This reading maintains that the remarks of the _Tractatus_ form a sequential chain: The role of the numbers is to indicate how remarks on different levels are interconnected to form a concise, surveyable and unified whole.

What is the role of sceptical scenarios—dreams, evil demons, brains in a vat—in scep- tical arguments? According to the error view, sceptical scenarios illustrate the possibil- ity of massive falsity in one’s beliefs, whereas according to the ignorance view, they illustrate the possibility of massive ignorance not necessarily due to falsity. In this paper, the ignorance view is defended by surveying the arguments in favour of it and by replying to two pressing objections against it. According to the first objection, (...) the ignorance view illicitly introduces the kk-principle into sceptical arguments. In reply I argue that kk is not less plausible than its main rival, the closure principle. According to the second objection, relying on veridical ignorance-possibilities contradicts the transparency of belief. In reply I introduce a version of transparency that is consistent with the ignorance view. (shrink)

The negation thesis concerning ignorance ("Nichtwissen") states that someone is ignorant about p if and only if she is does not know that p, or briefly, that ignorance is the negation of knowledge. We argue that there are no compelling arguments against the negation thesis. Even though, depending on the context of the conversation, the focus of an ascription of ignorance will be on one of the conditions for knowledge, all four types of ignorance are possible: ignorance due to falsity, (...) ignorance due to lack of belief, ignorance due to lack of justification, and ignorance due to epistemic luck. Then we discuss the relevance of the distinction between known unknowns and unknown unknowns, and the surprising idea that every strong belief may be identified with an unknown unknown. A desire not to know can be present for a variety of reasons. It may be either symmetrical (not wanting to know whether p) or asymmetrical (not wanting to know that p if p should be true). We argue for the thesis that the desire not to know usually amounts to a desire to preserve the epistemic status quo. The potential applications of these distinctions to the alleged right not to know particularly in medical contexts are largely left open in this paper. (shrink)

In Knowledge and its Limits (2000) Williamson defends not only the negative claim that knowledge cannot be analysed, but also the positive claim that knowledge is the most general factive mental state. In this paper two objections to the positive claim are presented: First, knowledge is not more general than e. g. seeing. After discussing several alleged examples of seeing without knowing a new example is offered. Although both seeing and knowing are incompatible with luck, they are incompatible with different (...) kinds of luck. Secondly, factive mental states that are more general than knowledge are conceivable. Williamson's characterisation of knowledge as being the most general factive mental state is not substantial enough to pick out exactly one state. The idea that there is such a thing as a maximal factive mental state cannot be sustained merely on the assumption that knowledge is unanalysable. (shrink)

Although the underrepresentation of women in academic philosophy is well-known and hard to overlook, philosophers started to pay more attention to the actual data on and potential explanations of the underrepresentation of women in philosophy only in the last decade and predominately in anglophone countries. The data I present in this paper deal with introductory logic courses at German universities (gender of textbook authors, gender of logic course instructors, student grades by gender at one university). Two results are particularly noteworthy: (...) For one, logic teaching in Germany is currently predominantly male and even more male than philosophy teaching as a whole. For another, there is no evidence for any differences between grades of female and male students. The student grade data, however, illustrate how statistical phenomena like Simpson's paradox can explain how male students can appear to achieve better grades than female students even if there is no underlying difference: When correcting for students’ major (philosophy vs. STEM), logic grades of male and female students are remarkably similar. Although the scope of the data presented here is limited, they allow to add further details to an emerging map of the profession. I close with some suggestions for avoiding stereotyping logic as “male”. (shrink)

Transmission arguments against closure of knowledge base the case against closure on the premise that a necessary condition for knowledge is not closed. Warfield argues that this kind of argument is fallacious whereas Brueckner, Murphy and Yan try to rescue it. According to them, the transmission argument is no longer fallacious once an implicit assumption is made explicit. I defend Warfield’s objection by arguing that the various proposals for the unstated assumption either do not avoid the fallacy or turn the (...) central premise of the transmission argument, namely that a necessary condition is not closed, into a redundant and superfluous premise. I conclude that Warfield’s advice is still to be heeded: Arguments against closure must not rely essentially on the premise that a necessary condition for knowledge is not closed. (shrink)

Watershed planning has typically been approached as a technical problem in which water quality and quantity as influenced by the hydrology, topography, soil composition, and land use of a watershed are the significant variables. However, it is the human uses of land and water as resources that stimulate governments to seek planning. For the past decade or more, many efforts have been made to create democratic planning processes, which, it is hoped, will be viewed as legitimate by those the plans (...) regulate. This article uses a case study of the Cache River watershed in southernmost Illinois to analyze the complicated historical and political economic context of a specific watershed planning process that occurred from 1993 through 1995. This article assesses the claims made about the democratic, grass-roots, deliberative nature of the planning process and casts doubt on the legitimacy of its outcomes. It also proposes an alternative form of governance that would be both democratic and capable of generating outcomes viewed as legitimate by most affected parties. (shrink)

Die grundlegenden Thesen der Neurowissenschaften zu Erkenntnis und Wahrheit werden vorgestellt und im nächsten Schritt von der Antike bis in die Moderne zurückverfolgt. Dabei erweist sich die skeptische Schule des Pyrrhon von Elis, vermittelt durch Sextus Empiricus, bis heute als ideengeschichtlich äußerst wirkmächtige Kraft. Viele der (auch bezüglich der Konstitution moderner Naturwissenschaften) einflussreichsten Philosophen führten ihr Erbe weiter, übernahmen damit jedoch auch höchst problematische Ansichten, welche im Zuge der Ausarbeitung der historischen Zusammenhänge kritisch kommentiert werden.

Tim Crane addresses the ancient question of how it is possible to think about what does not exist. He argues that the representation of the non-existent is a pervasive feature of our thought about the world, and that to understand thought's representational power ('intentionality') we need to understand the representation of the non-existent.

Elements of Mind provides a unique introduction to the main problems and debates in contemporary philosophy of mind. Author Tim Crane opposes those currently popular conceptions of the mind that divide mental phenomena into two very different kinds (the intentional and the qualitative) and proposes instead a challenging and unified theory of all the phenomena of mind. In light of this theory, Crane engages students with the central problems of the philosophy of mind--the mind-body problem, the problem of intentionality (or (...) mental representation), the problem of consciousness, and the problem of perception--and attempts to find solutions to these problems. A fresh and engaging exploration of the main issues in the philosophy of mind, Elements of Mind is easily accessible to students with no background in the subject. (shrink)

Abstract The only biologically respectable notion of human nature is an extremely permissive one that names the reliable dispositions of the human species as a whole. This conception offers no ethical guidance in debates over enhancement, and indeed it has the result that alterations to human nature have been commonplace in the history of our species. Aristotelian conceptions of species natures, which are currently fashionable in meta-ethics and applied ethics, have no basis in biological fact. Moreover, because our folk psychology (...) finds this misleading Aristotelian conception highly tempting, we are in fact better off if we refrain from mentioning human nature altogether in debates over enhancement.

The purpose of this paper is to present the results of a natural experiment involving academic cheating by university students. We explore the relationship of moral judgment to actual behavior, as well as the relationship between the honesty of students self-reports and the extent of cheating. We were able to determine the extent to which students actually cheated on the take-home portion of an accounting exam. The take-home problem was not assigned with the intent of inducing cheating among students. However, (...) the high rate of observed cheating prompted the instructor to return to class and ask the students to provide information on their motivation. The students' responses are the data analyzed in this natural experiment. We found that in a simple regression the relationship between moral judgment scores and cheating behavior was insignificant. However, when we tested whether including Utilizer scores affected the relationship of cheating and moral judgment we found that Utilizer affected the relationship significantly. Finally, we found that moral judgment and honesty were not related, but higher levels of cheating behavior related to less honesty. (shrink)

The ability to focus on relevant information is central to human cognition. It is therefore hardly unsurprising that the notion of relevance appears across a range of different dis- ciplines. As well as its central role in relevance-theoretic pragmatics, for example, rele- vance is also a core concept in the affective sciences, where there is consensus that for a particular object or event to elicit an emotional state, that object or event needs to be relevant to the person in whom (...) that state is elicited. Despite this, although some affective scientists have carefully considered what emotional relevance might mean, surprisingly little research has been dedicated to providing a definition. Since, by contrast, the relevance-theoretic notion of relevance is carefully defined, our primary aim is to compare relevance as it exists in affective science and in relevance theory, A further aim is to redress what we perceive to be an imbalance: Affective scientists have made great strides in understanding the processes of emotion elicitation/responses etc., but despite the fact that among humans the communication of information about emotional states is ubiquitous, pragmatists have tended to ignore it. We conclude, therefore, that affective science and relevance theory have much to learn from each other. (shrink)

Godfrey-Smith ( 2001 ) has distinguished three types of adaptationism. This article builds on his analysis, and revises it in places, by distinguishing seven varieties of adaptationism. This taxonomy allows us to clarify what is at stake in debates over adaptationism, and it also helps to cement the importance of Gould and Lewontin’s ‘Spandrels’ essay. Some adaptationists have suggested that their essay does not offer any coherent alternative to the adaptationist programme: it consists only in an exhortation to test adaptationist (...) hypotheses more thoroughly than was usual in the 1970s. Here it is argued that the ‘Spandrels’ paper points towards a genuinely non-adaptationist methodology implicit in much evolutionary developmental biology. This conclusion helps to expose the links between older debates over adaptationism and more recent questions about the property of evolvability. (shrink)

Historically, interjections have been treated in two different ways: as part of language, or as non-words signifying feelings or states of mind. In this paper, I assess the relative strengths and weaknesses of two contemporary approaches that reflect the historical dichotomy, and suggest a new analysis which preserves the insights of both. Interjections have a natural and a coded element, and are better analysed as falling at various points along a continuum between ‘showing’ and ‘saying’. These two notions are characterised (...) in theoretical terms, and some implications of the proposed approach are considered. (shrink)

Grice (1957) drew a distinction between natural(N) and non–natural(NN) meaning, and showed how the latter might be characterised in terms of intentions and the recognition of intentions. Focussing on the role of natural signs and natural behaviours in communication, this paper makes two main points. First, verbal communication often involves a mixture of natural and non–natural meaning and there is a continuum of cases between showing and meaningNN. This suggests that pragmatics is best seen as a theory of intentional verbal (...) communication rather than a theory of meaningNN. Second, some natural behaviours have a signalling function: they are, in effect, natural codes. Such behaviours do not fit easily into Grice's distinction between natural and non–natural meaning, which suggests it is not exhaustive. (shrink)

This paper studies the relationship between labelled and nested calculi for propositional intuitionistic logic, first-order intuitionistic logic with non-constant domains and first-order intuitionistic logic with constant domains. It is shown that Fitting’s nested calculi naturally arise from their corresponding labelled calculi—for each of the aforementioned logics—via the elimination of structural rules in labelled derivations. The translational correspondence between the two types of systems is leveraged to show that the nested calculi inherit proof-theoretic properties from their associated labelled calculi, such as (...) completeness, invertibility of rules and cut admissibility. Since labelled calculi are easily obtained via a logic’s semantics, the method presented in this paper can be seen as one whereby refined versions of labelled calculi (containing nested calculi as fragments) with favourable properties are derived directly from a logic’s semantics.

Elliott Sober and his defenders think of selection, drift, mutation, and migration as distinct evolutionary forces. This paper exposes an ambiguity in Sober's account of the force of selection: sometimes he appears to equate the force of selection with variation in fitness, sometimes with ‘selection for properties’. Sober's own account of fitness as a property analogous to life-expectancy shows how the two conceptions come apart. Cases where there is selection against variance in offspring number also show that selection and drift (...) cannot be distinguished in the way Sober hopes for. These issues have significance beyond the parochial matter of the coherence of Sober's system. There is no good principled answer to the question of which features of a population should count among the contributors to fitness. This means there is no non-arbitrary account of the nature of selection. (shrink)

We provide a direct method for proving Craig interpolation for a range of modal and intuitionistic logics, including those containing a "converse" modality. We demonstrate this method for classical tense logic, its extensions with path axioms, and for bi-intuitionistic logic. These logics do not have straightforward formalisations in the traditional Gentzen-style sequent calculus, but have all been shown to have cut-free nested sequent calculi. The proof of the interpolation theorem uses these calculi and is purely syntactic, without resorting to embeddings, (...) semantic arguments, or interpreted connectives external to the underlying logical language. A novel feature of our proof includes an orthogonality condition for defining duality between interpolants. (shrink)

This thesis introduces the "method of structural refinement", which serves as a means of transforming the relational semantics of a modal and/or constructive logic into an 'economical' proof system by connecting two proof-theoretic paradigms: labelled and nested sequent calculi. The formalism of labelled sequents has been successful in that cut-free calculi in possession of desirable proof-theoretic properties can be automatically generated for large classes of logics. Despite these qualities, labelled systems make use of a complicated syntax that explicitly incorporates the (...) semantics of the associated logic, and such systems typically violate the subformula property to a high degree. By contrast, nested sequent calculi employ a simpler syntax and adhere to a strict reading of the subformula property, making such systems useful in the design of automated reasoning algorithms. However, the downside of the nested sequent paradigm is that a general theory concerning the automated construction of such calculi (as in the labelled setting) is essentially absent, meaning that the construction of nested systems and the confirmation of their properties is usually done on a case-by-case basis. The refinement method connects both paradigms in a fruitful way, by transforming labelled systems into nested (or, refined labelled) systems with the properties of the former preserved throughout the transformation process. To demonstrate the method of refinement and some of its applications, we consider grammar logics, first-order intuitionistic logics, and deontic STIT logics. The introduced refined labelled calculi will be used to provide the first proof-search algorithms for deontic STIT logics. Furthermore, we employ our refined labelled calculi for grammar logics to show that every logic in the class possesses the effective Lyndon interpolation property. (shrink)

Deirdre Wilson provides a reflective overview of a volume devoted to the historic application of relevance-theoretic ideas to literary studies. She maintains a view argued elsewhere that the putative non-propositional nature of literary effects are an illusion, a view which dates to Sperber and Wilson : “If you look at [non-propositional] affective effects through the microscope of relevance theory, you see a wide array of minute cognitive [i.e., propositional] effects.” This paper suggests an alternative, that modern-day humans have two apparently (...) different modes of expressing and interpreting information: one of these is a system in which propositional, cognitive effects dominate; the other involves direct, non-propositional effects. The paper concludes by describing two ways such affects might be assimilated into relevance theory. The first, to accept that humans are much more than merely cognitive organisms; the second, to rethink quite radically what we mean by cognition. (shrink)

This work provides proof-search algorithms and automated counter-model extraction for a class of STIT logics. With this, we answer an open problem concerning syntactic decision procedures and cut-free calculi for STIT logics. A new class of cut-free complete labelled sequent calculi G3LdmL^m_n, for multi-agent STIT with at most n-many choices, is introduced. We refine the calculi G3LdmL^m_n through the use of propagation rules and demonstrate the admissibility of their structural rules, resulting in auxiliary calculi Ldm^m_nL. In the single-agent case, we (...) show that the refined calculi Ldm^m_nL derive theorems within a restricted class of (forestlike) sequents, allowing us to provide proof-search algorithms that decide single-agent STIT logics. We prove that the proof-search algorithms are correct and terminate. (shrink)

ArgumentThe article takes as its starting point the relationship of academic economists and the wider society. First, various bodies of literature that deal empirically with this matter are discussed: epistemologically, they range from a bold structuralism via a form of symbolic interactionism to a form of radical constructivism. A Bourdieusian approach is recommended to complement these perspectives with a comprehensive perspective that is sensible to the cultural differences between social groups. Starting from the established notions of field, capital and habitus, (...) the article then attempts to go the initial steps towards formulating a theory of the specificity of academic economics, taking Germany as its example. For that it uses and compares in-depth interviews of recognized and non-recognized German economics students. It shows the thorough interweaving of specific normative and positive dispositions into a conviction of objectivity and disinterestedness. This exploratory empirical induction furthers follow-up questions, the empirical answering of which may help to gain a more complete understanding of the actions and thoughts of economists in their specific contexts.

An apparently quite specific question that was addressed by both Confucius and Socrates has attracted much attention in Sino-Hellenistic comparative philosophy. Their respective responses to the question of how a son should respond if his father commits a crime are found in Confucius' Analects 13:18 and in Plato's Euthyphro. This essay assesses three comparative analyses of these responses with particular reference to their underlying assertions of commonality, that is, the assumptions or presuppositions of commonality that serve to justify the comparative (...) exercise in the first instance. The authors suggest that two of the analyses assert commonality between their two responses from a Confucian standpoint, while the third constructs commonality from a Socratic standpoint. The authors argue that the response of Confucius focuses specifically on the issue of xiao in the concrete situation presented to him, whereas Socrates uses the issue to investigate the different question known as the "Euthyphro dilemma." Some brief conclusions are drawn regarding comparative philosophical analysis in general and about comparing the responses of Confucius and Socrates in these passages in particular. (shrink)

The pressure of oversight and scrutiny in the business-to-business purchasing process has the potential to cause psychological distress in purchasing professionals, giving rise to apprehensions about being ethically inappropriate.

An inductively derived conceptual framework is presented for ethical purchasing dissonance that explores its potential antecedents and consequences; illustrative propositions are presented, and managerial implications are (...) discussed.

Supporters of political realism and republicanism as well as students of political feasibility and non-ideal theory progressively focus on the dimension of power in the political relation. Yet we lack the theoretical framework to represent these features of power. In this essay, I take a first step towards designing the necessary conceptual tools for such a framework by analyzing the relations between the concepts of power and normativity that define the political relation. Adopting a ‘methodological cynicism’, I analyse the reasons (...) that motivate cynics who are only interested in power to obey a norm against force or violence and to seek legitimacy. This allows us to characterize external or mediate relations between power and normativity (such as the relation underlying political theory’s ambition of offering normative guidance for power) and identify internal and immediate relations between power and normativity.

argues that when reproduction is sexual, natural selection can explain why individual organisms possess the traits they do. In stating his argument Matthen makes use of a conception of individual organisms as receptacles for collections of genes—a conception that cannot do the work Matthen requires of it. Either these receptacles are abstract objects, such as bare possibilities for organisms, or they are concrete. The first reading is too weak, since it allows selection to explain individual traits in both sexual and (...) asexual contexts. The only concrete entities we might think of as receptacles for collections of genes are male or female gametes. It is true that in the sexual context selection explains why an individual gamete combines with a second gamete of one type rather than another; however, this is not to say that selection explains why an individual organism has the traits it does.

What, if anything, is wrong with typological thinking? The question is important, for some evolutionary developmental biologists appear to espouse a form of typology. I isolate four allegations that have been brought against it. They include the claim that typological thinking is mystical; the claim that typological thinking is at odds with the fact of evolution; the claim that typological thinking is committed to an objectionable metaphysical view, which Elliott Sober calls the ‘natural state model’; and finally the view (endorsed (...) by Ron Amundson and Günter Wagner) that typological thinking—and specifically evolutionary developmental biology’s typological thinking—is committed to a peculiar form of causation that does not fit neatly into the causal models endorsed by population genetics. I argue that, properly understood, the typological thinking of evolutionary developmental biology does not run into any of these problems. *Received April 2008; revised August 2009. †To contact the author, please write to: Department of History and Philosophy of Science, University of Cambridge, Free School Lane, CB2 3RH Cambridge, United Kingdom; e‐mail: [email protected].

The four tenets of the Strong Program are compatible with a scientific realism founded on an externalist epistemology. Such an epistemology allows that appropriate norms of rationality may differ from time to time, and from community to community, and thereby enables the realist to embrace strong forms of the ‘symmetry principle’. It also suggests a fruitful collaborative research program in externalist social epistemology. Some of what the Edinburgh School says about truth can also be accepted. But the realist should reject (...) the School's argument for the claim that there is no distinction between being rational and being locally accepted as rational, which seems to rest on a kind of epistemological internalism.

In a recent paper, Aidan Lyon and Mark Colyvan have proposed an explanation of the structure of the bee's honeycomb based on the mathematical Honeycomb Conjecture. This explanation has instantly become one of the standard examples in the philosophical debate on mathematical explanations of physical phenomena. In this critical note, I argue that the explanation is not scientifically adequate. The reason for this is that the explanation fails to do justice to the essentially three-dimensional structure of the bee's honeycomb.

Michael and has argued that species have intrinsic essences. This paper rebuts Devitt’s arguments, but in so doing it shores up the anti-essentialist consensus in two ways that have more general interest. First, species membership can be explanatory even when species have no essences; that is, Tamsin’s membership of the tiger species can explain her stripyness, without this committing us to any further claim about essential properties of tigers. Second, even the views of species that appear most congenial to essentialism—namely (...) phenetic and genotypic cluster accounts—do not entail strong forms of intrinsic essentialism. (shrink)

The UK-based deliberations that led up to the legalisation of two new ‘mitochondrial donation’ techniques in 2015, and which continued after that time as regulatory details were determined, featured a division of advisory labour that is common when decisions are made about new technologies. An expert panel was convened by the Human Fertilisation and Embryology Authority, charged with assessing the scientific and technical aspects of these techniques. Meanwhile, the Nuffield Council on Bioethics addressed the ethical issues. While this division of (...) labour was undertaken in the name of thoroughness, I argue here that it can have the unintended consequence that hybrid questions that simultaneously involve ethical and technical aspects—especially questions about where to set evidential thresholds for the acceptance of new technology—do not receive enough attention.
