That holobionts are units of selection squares poorly with the observation that microbes are often recruited from the environment, not passed down vertically from parent to offspring, as required for collective reproduction. The taxonomic makeup of a holobiont’s microbial community may vary over its lifetime and differ from that of conspecifics. In contrast, biochemical functions of the microbiota and contributions to host biology are more conserved, with taxonomically variable but functionally similar microbes recurring across generations and hosts. To save what (...) is of interest in holobiont thinking, we propose casting metabolic and developmental interaction patterns, rather than the taxa responsible for them, as units of selection. Such units need not directly reproduce or form parent-offspring lineages: their prior existence has created the conditions under which taxa with the genes necessary to carry out their steps have evolved in large numbers. These taxa or genes will reconstruct the original interaction patterns when favorable conditions occur. Interaction patterns will vary in ways that affect the likelihood of and circumstances under which such reconstruction occurs. Thus, they vary in fitness, and evolution by natural selection will occur at this level. It is on the persistence, reconstruction, and spread of such interaction patterns that students of holobiosis should concentrate, we suggest. This model also addresses other multi-species collectively beneficial interactions, such as biofilms or biogeochemical cycles maintaining all life. (shrink)

Wayne C. Booth argues for the relocation of ethics to the center of our engagement with literature.

To be a doxastic deontologist is to claim that there is such a thing as an ethics of belief (or of our doxastic attitudes in general). In other words, that we are subject to certain duties with respect to our doxastic attitudes, the non-compliance with which makes us blameworthy and that we should understand doxastic justification in terms of these duties. In this paper, I argue that these duties are our all things considered duties, and not our epistemic or moral (...) duties, for example. I show how this has the surprising result that, if deontologism is a thesis about doxastic justification, it entails that there is no such thing as epistemic or moral justification for a belief that p. I then suggest why this result, though controversial, may have some salutary consequences: primarily that it helps us make some sense of an otherwise puzzling situation regarding doxastic dilemmas. -/- .

A recent development in biology has been the growing acceptance that holobionts, entities comprised of symbiotic microbes and their host organisms, are widespread in nature. There is agreement that holobionts are evolved outcomes, but disagreement on how to characterize the operation of natural selection on them. The aim of this paper is to articulate the contours of the disagreement. I explain how two distinct foundational accounts of the process of natural selection give rise to competing views about evolutionary individuality.

In _The Company We Keep_, Wayne C. Booth argues for the relocation of ethics to the center of our engagement with literature. But the questions he asks are not confined to morality. Returning ethics to its root sense, Booth proposes that the ethical critic will be interested in any effect on the ethos, the total character or quality of tellers and listeners. Ethical criticism will risk talking about the quality of _this_ particular encounter with _this_ particular work. Yet it will (...) give up the old hope for definitive judgments of "good" work and "bad." Rather it will be a conversation about _many_ kinds of personal and social goods that fictions can serve or destroy. While not ignoring the consequences for conduct of engaging with powerful stories, it will attend to that more immediate topic, What happens to us _as we read_? Who am I, _during the hours of reading or listening_? What is the quality of the life I lead in the company of these would-be friends? Through a wide variety of periods and genres and scores of particular works, Booth pursues various metaphors for such engagements: "friendship with books," "the exchange of gifts," "the colonizing of worlds," "the constitution of commonwealths." He concludes with extended explorations of the ethical powers and potential dangers of works by Rabelais, D. H. Lawrence, Jane Austen, and Mark Twain. (shrink)

This paper provides a defence of the thesis that responsible belief is permissible rather than obliged belief. On the Uniqueness Thesis (UT), our evidence is always such that there is a unique doxastic attitude that we are obliged to have given that evidence, whereas the Permissibility Thesis (PT) denies this. After distinguishing several varieties of UT and PT, we argue that the main arguments that have been levied against PT fail. Next, two arguments in favour of PT are provided. Finally, (...) two motivations for PT are put forward by showing that PT is entailed by two views that are quite popular among theorists working on doxastic responsibility. If the arguments in this paper are successful, we not only have good reasons to prefer PT over UT, but also good reasons to think that the gap between the ways in which we are meant to normatively assess belief and action may not be as wide as has been thought.

In men, high levels of endogenous testosterone (T) seem to encourage behavior intended to dominate other people. Sometimes dominant behavior is aggressive, its apparent intent being to inflict harm on another person, but often dominance is expressed nonaggressively. Sometimes dominant behavior takes the form of antisocial behavior, including rebellion against authority and law breaking. Measurement of T at a single point in time, presumably indicative of a man's basal T level, predicts many of these dominant or antisocial behaviors. T not (...) only affects behavior but also responds to it. The act of competing for dominant status affects male T levels in two ways. First, T rises in the face of a challenge, as if it were an anticipatory response to impending competition. Second, after the competition, T rises in winners and declines in losers. Thus, there is a reciprocity between T and dominance behavior, each affecting the other. We contrast a reciprocal model, in which T level is variable, acting as both a cause and effect of behavior, with a basal model, in which T level is assumed to be a persistent trait that influences behavior. An unusual data set on Air Force veterans, in which data were collected four times over a decade, enables us to compare the basal and reciprocal models as explanations for the relationship between T and divorce. We discuss sociological implications of these models. (shrink)

What, according to proponents of doxastic deontologism, is responsible belief? In this paper, we examine two proposals. Firstly, that responsible belief is blameless belief (a position we call DDB) and, secondly, that responsible belief is praiseworthy belief (a position we call DDP). We consider whether recent arguments in favor of DDP, mostly those recently offered by Brian Weatherson, stand up to scrutiny and argue that they do not. Given other considerations in favor of DDP, we conclude that the deontologist should (...) maintain that doxastic responsibility is a concept about freedom from appropriate blame. (shrink)

According to the doxastic compatibilist, compatibilist criteria with respect to the freedom of action rule-in our having free beliefs. In Booth (Philosophical Papers 38:1–12, 2009), I challenged the doxastic compatibilist to either come up with an account of how doxastic attitudes can be intentional in the face of it very much seeming to many of us that they cannot. Or else, in rejecting that doxastic attitudes need to be voluntary in order to be free, to come up with a principled (...) account of how her criteria of doxastic freedom are criteria of freedom. In two recent papers, Steup (Synthese 188:145–163, 2012; Dialectica 65(4):559–576, 2011) takes up the first disjunct of the challenge by proposing that even though beliefs cannot be practically intentional, they can be epistemically intentional. McHugh (McHugh forthcoming) instead takes up the second disjunct by proposing that the freedom of belief be modelled not on the freedom of action but on the freedom of intention. I argue that both Steup’s and McHugh’s strategies are problematic. (shrink)

After a number of decades of research into the dynamics of rational belief, the belief revision theory community remains split on the appropriate handling of sequences of changes in view, the issue of so-called iterated revision. It has long been suggested that the matter is at least partly settled by facts pertaining to the results of various single revisions of one’s initial state of belief. Recent work has pushed this thesis further, offering various strong principles that ultimately result in a (...) wholesale reduction of iterated to one-shot revision. The present paper offers grounds to hold that these principles should be significantly weakened and that the reductionist thesis should ultimately be rejected. Furthermore, the considerations provided suggest a close connection between the logic of iterated belief change and the logic of evidential relevance. (shrink)

Orthodox semantics for natural language modals give rise to two puzzles for their interactions with disjunction: Ross’s puzzle and the puzzle of free choice permission. It is widely assumed that each puzzle can be explained in terms of the licensing of ‘Diversity’ inferences: from the truth of a possibility or necessity modal with an embedded disjunction, hearers infer that each disjunct is compatible with the relevant set of worlds. I argue that Diversity inferences are too weak to explain the full (...) range of data. Instead, I argue, modals with embedded disjunctions license ‘Independence’ inferences: from the truth of a modal with an embedded disjunction, hearers infer that each disjunct is an independent alternative among the relevant set of worlds. I then develop a bilateral inquisitive semantics for modals that predicts the validity of these Independence inferences. My account vindicates common intuitions about both Ross’s puzzle and the puzzle of free choice permission, and explains the full range of data. (shrink)

When should I change my mind? What can I believe and what must I doubt? In this new "philosophy of good reasons" Wayne C. Booth exposes five dogmas of modernism that have too often inhibited efforts to answer these questions.

In this paper I discuss two claims; the first is the claim that state-given reasons for belief are of a radically different kind to object-given reasons for belief. The second is that, where this last claim is true, epistemic reasons are object-given reasons for belief (EOG). I argue that EOG has two implausible consequences: (i) that suspension of judgement can never be epistemically justified, and (ii) that the reason that epistemically justifies a belief that p can never be the reason (...) for which one believes that p.

Much of the force behind doxastic involuntarism comes from our pre-theoretical judgement that any effort to form a belief simply by intending to form it must remain unsuccessful. However, despite this, ordinary language use of locutions like “chose to believe” are common. In this article, we present new experimental data that shows that the prevalence of ordinary language talk of “chosen beliefs” is no obstacle to doxastic involuntarism in a standard sense (pace Turri et al. 2018). While we employ the (...) methods of experimental philosophy, our argument also concerns the fundamental question as to what those methods can achieve: as is typical of philosophical debates, the debate over doxastic voluntarism involves a refined theoretical concept, specifically a refined concept of voluntary belief. In such debates, we cannot determine our pre-theoretical position by conducting surveys on those who may not yet own the requisite theoretical concepts. (shrink)

We report an experiment investigating the “special-process” theory of insight problem solving, which claims that insight arises from non-conscious, non-reportable processes that enable problem re-structuring. We predicted that reducing opportunities for speech-based processing during insight problem solving should permit special processes to function more effectively and gain conscious awareness, thereby facilitating insight. We distracted speech-based processing by using either articulatory suppression or irrelevant speech, with findings for these conditions supporting the predicted insight facilitation effect relative to silent working or thinking (...) aloud. The latter condition was included to investigate the currently contested effect of “verbal overshadowing” on insight, whereby thinking aloud is claimed to hinder the operation of special, non-reportable processes. Whilst verbal overshadowing was not evident in final solution rates, there was nevertheless support for verbal overshadowing up to and beyond.. (shrink)

Among mycologists, questions persist about what entities should be treated as the fundamental units of fungal populations. This article articulates a coherent view about populations of heterokaryotic fungi and the individuals that comprise them. Using Godfrey-Smith’s minimal concept of a Darwinian population, I argue that entities at two levels of the biological hierarchy satisfy the minimal concept in heterokaryotic fungi: mycelia and nuclei. I provide a preliminary answer to the question of how to understand the relation between these two populations. (...)

Eukaryogenesis is widely viewed as an improbable evolutionary transition uniquely affecting the evolution of life on this planet. However, scientific and popular rhetoric extolling this event as a singularity lacks rigorous evidential and statistical support. Here, we question several of the usual claims about the specialness of eukaryogenesis, focusing on both eukaryogenesis as a process and its outcome, the eukaryotic cell. We argue in favor of four ideas. First, the criteria by which we judge eukaryogenesis to have required a genuinely (...) unlikely series of events 2 billion years in the making are being eroded by discoveries that fill in the gaps of the prokaryote:eukaryote “discontinuity.” Second, eukaryogenesis confronts evolutionary theory in ways not different from other evolutionary transitions in individuality; parallel systems can be found at several hierarchical levels. Third, identifying which of several complex cellular features confer on eukaryotes a putative richer evolutionary potential remains an area of speculation: various keys to success have been proposed and rejected over the five-decade history of research in this area. Fourth, and perhaps most importantly, it is difficult and may be impossible to eliminate eukaryocentric bias from the measures by which eukaryotes as a whole are judged to have achieved greater success than prokaryotes as a whole. Overall, we question whether premises of existing theories about the uniqueness of eukaryogenesis and the greater evolutionary potential of eukaryotes have been objectively formulated and whether, despite widespread acceptance that eukaryogenesis was “special,” any such notion has more than rhetorical value.

The debate between “Normativists” and “Teleologists” about the normativity of belief has been taken to hinge on the question of which of the two views best explains why it is that we cannot believe at will. Of course, this presupposes that there is an explanation to be had. Here, I argue that this supposition is unwarranted, that Doxastic Involuntarism is merely contingently true. I argue that this is made apparent when we consider that suspended judgement must be involuntary if belief (...) is, that suspended judgment is not a belief, and that the aim or norm of suspended judgement cannot be constitutive if suspended judgement is not a belief.

In this paper I consider whether there can be such things as epistemic reasons for action. I consider three arguments to the contrary and argue that none are successful, being either somewhat question-begging or too strong by ruling out what most epistemologists think is a necessary feature of epistemic justification, namely the epistemic basing relation. I end by suggesting a "non-cognitivist" model of epistemic reasons that makes room for there being epistemic reasons for action and suggest that this model may (...) support moral realism. (shrink)

Matthias Steup (Steup 2008) has recently argued that our doxastic attitudes are free by (i) drawing an analogy with compatibilism about freedom of action and (ii) denying that it is a necessary condition for believing at will that S's having an intention to believe that p can cause S to believe that p . In this paper, however, I argue that the strategies espoused in (i) and (ii) are incompatible.

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

Proponents of semiotic arguments against the commodification of certain goods face the following challenge: formulate your argument such that it does not appeal to immoral consequences, nor is really an argument showing that we ought to reform the meaning we give to commodification. I here attempt to meet this challenge via appeal to the notion of what I call proto-on-a-par value. Under this construal, the semiotic argument yields that the commodification of certain goods necessarily signals value choice, where value choice (...) ought not to be signaled. (shrink)

Most approaches to iterated belief revision are accompanied by some motivation for the use of the proposed revision operator (or family of operators), and typically encode enough information in the epistemic state of an agent for uniquely determining one-step revision. But in those approaches describing a family of operators there is usually little indication of how to proceed uniquely after the first revision step. In this paper we contribute towards addressing that deficiency by providing a formal framework which goes beyond (...) the first revision step in two ways. First, the framework is obtained by enriching the epistemic state of an agent starting from the following intuitive idea: we associate to each world x two abstract objects x⁺ and x⁻, and we assume that, in addition to preferences over the set of worlds, we are given preferences over this set of objects as well. The latter can be considered as meta-information encoded in the epistemic state which enables us to go beyond the first revision step of the revision operator being applied, and to obtain a unique set of preferences over worlds. We then extend this framework to consider, not only the revision of preferences over worlds, but also the revision of this extended structure itself. We look at some desirable properties for revising the structure and prove the consistency of these properties by giving a concrete operator satisfying all of them. Perhaps more importantly, we show that this framework has strong connections with two other types of constructions in related areas. Firstly, it can be seen as a special case of preference aggregation which opens up the possibility of extending the frame-work presented here into a full-fledged framework for preference aggregation and social choice theory. Secondly, it is related to existing work on the use of interval orderings in a number of different contexts. (shrink)

Richard Foley has suggested that the search for a good theory of epistemic justification and the analysis of knowledge should be conceived of as two distinct projects. However, he has not offered much support for this claim, beyond highlighting certain salutary consequences it might have. In this paper, I offer some further support for Foley’s claim by offering an argument and a way to conceive the claim in a way that makes it as plausible as its denial, and thus levelling (...) the playing field. The burden of proof then lies with those who seek to deny Foley’s radical suggestion. (shrink)

I argue that the claim that epistemic ought is incommensurable is self-defeating. My argument, however, depends on the truth of the premise that there can be not only epistemic reasons for belief, but also non-epistemic reasons for belief. So I also provide some support for that claim.

I introduce a new version of Moral Error Theory, which I call Type-B Moral Error Theory. According to a Type-B theorist there are no facts of the kind required for there to be morality in stricto sensu, but there can be irreducible ‘normative’ properties which she deems, strictly speaking, to be morally irrelevant. She accepts that there are instrumental all things considered oughts, and categorical pro tanto oughts, but denies that there are categorical all things considered oughts on pain of (...) requiring ‘queer’ facts to obtain. I detail the most central motivation of this version of the theory against its more traditional rival, according to which there are no irreducible normative properties at all. The motivation is that it, unlike its rival, can successfully be defended against the notorious charge of self-defeat. (shrink)

This book is an introduction to Islamic Philosophy, beginning with its Medieval inception, right through to its more contemporary incarnations. Using the language and conceptual apparatus of contemporary Anglo-American ‘Analytic’ philosophy, this book represents a novel and creative attempt to rejuvenate Islamic Philosophy for a modern audience. It adopts a ‘rational reconstructive’ approach to the history of philosophy by affording maximum hermeneutical priority to the strongest possible interpretation of a philosopher’s arguments while also paying attention to the historical context in (...) which they worked. The central canonical figures of Medieval Islamic Philosophy – al-Kindi, al-Farabi, Avicenna, al-Ghazali, Averroes – are presented chronologically along with an introduction to the central themes of Islamic theology and the Greek philosophical tradition they inherited. The book then briefly introduces what the author collectively refers to as the ‘Pre-Modern’ figures including Suhrawardi, Mulla Sadra, and Ibn Taymiyyah, and presents all of these thinkers, along with their Medieval predecessors, as forerunners to the more modern incarnation of Islamic Philosophy: Political Islam.

The field of iterated belief change has focused mainly on revision, with the other main operator of AGM belief change theory, i.e. contraction, receiving relatively little attention. In this paper we extend the Harper Identity from single-step change to define iterated contraction in terms of iterated revision. Specifically, just as the Harper Identity provides a recipe for defining the belief set resulting from contracting A in terms of (i) the initial belief set and (ii) the belief set resulting from revision (...) by ¬A, we look at ways to define the plausibility ordering over worlds resulting from contracting A in terms of (iii) the initial plausibility ordering, and (iv) the plausibility ordering resulting from revision by ¬A. After noting that the most straightforward such extension leads to a trivialisation of the space of permissible orderings, we provide a family of operators for combining plausibility orderings that avoid such a result. These operators are characterised in our domain of interest by a pair of intuitively compelling properties, which turn out to enable the derivation of a number of iterated contraction postulates from postulates for iterated revision. We finish by observing that a salient member of this family allows for the derivation of counterparts for contraction of some well known iterated revision operators, as well as for defining new iterated contraction operators.

This article aims to make a contribution to the conceptualization of mainstreaming gender equality promoted by the European Union. It starts by exploring the historical periodization of equal opportunities delivery strategies and challenging the compartmentalization of these developments. It suggests that equality policies can better be conceptualized in terms of a `three-legged equality stool', which recognizes the interconnectiveness of three perspectives — the equal treatment perspective, the women's perspective and the gender perspective. The article argues that the gender perspective has (...) been closely associated with strategies for mainstreaming gender equality, but that this association is misleading. As a result mainstreaming has remained a `fuzzy' concept, which in turn has led to many different styles and forms of practical implementation in European member states. (shrink)

The ethical practices of credit rating agencies, particularly following the 2008 financial crisis, have been subject to extensive analysis by economists, ethicists, and policymakers. We raise a novel issue facing CRAs that has to do with a problem concerning the transmission of epistemic status of ratings from CRAs to the beneficiaries of the ratings, and use it to provide a new challenge for regulators. Building on recent work in philosophy, we argue that since CRAs have different stakes than the beneficiaries (...) of the ratings in the ratings being accurate, what counts as knowledge concerning credit risk for a CRA may not count as knowledge for the beneficiary. Further, as it stands, many institutional investors are bound by law to make some of their investment decisions dependent on the ratings of officially recognized CRAs. We argue that the observation that the epistemic status of ratings does not transmit from CRAs to beneficiaries makes salient a new challenge for those who think current regulation regarding the CRAs is prudentially justified, namely, to show that the harm caused by acting on a rating that does not have epistemic status for beneficiaries is compensated by the benefit from them acting on a CRA rating that does have epistemic status for the CRA. Unlike most other commentators, therefore, we offer a defeasible reason to drop references to CRAs in prudential regulation of the financial industry. (shrink)

To contribute more effectively to conservation reform, environmental ethics needs a motivational turn, referenced to the best scientific information about motivation. I address the pivotal questions What actually motivates people to conserve nature? and What ought to motivate people to conserve nature? by proposing a framework for understanding motivations and developing motivationally relevant criteria for environmental ethics. The need for an adequate philosophy of psychology for moral philosophy, identified by Elizabeth Anscombe 50 years ago, remains. Only from a psychologically informed (...) motivational framework for morality can ethicists understand and address the widespread rhetoric behaviors gap plaguing conservation. (shrink)
