Plants from a handful of species provide the primary source of food for all people, yet this source is vulnerable to multiple stressors, such as disease, drought, and nutrient deficiency. With rapid population growth and climate uncertainty, the need to produce crops that can tolerate or resist plant stressors is more crucial than ever. Traditional plant breeding methods may not be sufficient to overcome this challenge, and methods such as highOthroughput sequencing and automated scoring of phenotypes can provide significant new (...) insights. Ontologies are essential tools for accessing and analysing the large quantities of data that come with these newer methods. As part of a larger project to develop ontologies that describe plant phenotypes and stresses, we are developing a plant disease extension of the Infectious Disease Ontology (IDOPlant). The IDOPlant is envisioned as a reference ontology designed to cover any plant infectious disease. In addition to novel terms for infectious diseases, IDOPlant includes terms imported from other ontologies that describe plants, pathogens, and vectors, the geographic location and ecology of diseases and hosts, and molecular functions and interactions of hosts and pathogens. To encompass this range of data, we are suggesting inOhouse ontology development complemented with reuse of terms from orthogonal ontologies developed as part of the Open Biomedical Ontologies (OBO) Foundry. The study of plant diseases provides an example of how an ontological framework can be used to model complex biological phenomena such as plant disease, and how plant infectious diseases differ from, and are similar to, infectious diseases in other organism.

The Plant Ontology (PO) (http://www.plantontology.org) (Jaiswal et al., 2005; Avraham et al., 2008) was designed to facilitate cross-database querying and to foster consistent use of plant-specific terminology in annotation. As new data are generated from the ever-expanding list of plant genome projects, the need for a consistent, cross-taxon vocabulary has grown. To meet this need, the PO is being expanded to represent all plants. This is the first ontology designed to encompass anatomical structures as well as growth and developmental stages (...) across such a broad taxonomic range. While other ontologies such as the Gene Ontology (GO) (The Gene Ontology Consortium, 2010) or Cell Type Ontology (CL) (Bard et al., 2005) cover all living organisms, they are confined to structures at the cellular level and below. The diversity of growth forms and life histories within plants presents a challenge, but also provides unique opportunities to study developmental and evolutionary homology across organisms.

The Plant Ontology (PO; http://www.plantontology.org/) is a publicly-available, collaborative effort to develop and maintain a controlled, structured vocabulary (“ontology”) of terms to describe plant anatomy, morphology and the stages of plant development. The goals of the PO are to link (annotate) gene expression and phenotype data to plant structures and stages of plant development, using the data model adopted by the Gene Ontology. From its original design covering only rice, maize and Arabidopsis, the scope of the PO has been expanded (...) to include all green plants. The PO was the first multi-species anatomy ontology developed for the annotation of genes and phenotypes. Also, to our knowledge, it was one of the first biological ontologies that provides translations (via synonyms) in non-English languages such as Japanese and Spanish. There are about 2.2 million annotations linking PO terms to over 110,000 unique data objects representing genes or gene models, proteins, RNAs, germplasm and Quantitative Traits Loci (QTLs) from 22 plant species. In this paper, we focus on the plant anatomical entity branch of the PO, describing the organizing principles, resources available to users, and examples of how the PO is integrated into other plant genomics databases and web portals. We also provide two examples of comparative analyses, demonstrating how the ontology structure and PO-annotated data can be used to discover the patterns of expression of the LEAFY (LFY) and terpene synthase (TPS) gene homologs.

The Planteome project provides a suite of reference and species-specific ontologies for plants and annotations to genes and phenotypes. Ontologies serve as common standards for semantic integration of a large and growing corpus of plant genomics, phenomics and genetics data. The reference ontologies include the Plant Ontology, Plant Trait Ontology, and the Plant Experimental Conditions Ontology developed by the Planteome project, along with the Gene Ontology, Chemical Entities of Biological Interest, Phenotype and Attribute Ontology, and others. The project also provides (...) access to species-specific Crop Ontologies developed by various plant breeding and research communities from around the world. We provide integrated data on plant traits, phenotypes, and gene function and expression from 95 plant taxa, annotated with reference ontology terms. (shrink)

Bio-ontologies are essential tools for accessing and analyzing the rapidly growing pool of plant genomic and phenomic data. Ontologies provide structured vocabularies to support consistent aggregation of data and a semantic framework for automated analyses and reasoning. They are a key component of the Semantic Web. This paper provides background on what bio-ontologies are, why they are relevant to botany, and the principles of ontology development. It includes an overview of ontologies and related resources that are relevant to plant science, (...) with a detailed description of the Plant Ontology (PO). We discuss the challenges of building an ontology that covers all green plants (Viridiplantae). Key results: Ontologies can advance plant science in four keys areas: 1. comparative genetics, genomics, phenomics, and development, 2. taxonomy and systematics, 3. semantic applications and 4. education. Conclusions: Bio-ontologies offer a flexible framework for comparative plant biology, based on common botanical understanding. As genomic and phenomic data become available for more species, we anticipate that the annotation of data with ontology terms will become less centralized, while at the same time, the need for cross-species queries will become more common, causing more researchers in plant science to turn to ontologies.

The Plant Ontology (PO) is a community resource consisting of standardized terms, definitions, and logical relations describing plant structures and development stages, augmented by a large database of annotations from genomic and phenomic studies. This paper describes the structure of the ontology and the design principles we used in constructing PO terms for plant development stages. It also provides details of the methodology and rationale behind our revision and expansion of the PO to cover development stages for all plants, particularly (...) the land plants (bryophytes through angiosperms). As a case study to illustrate the general approach, we examine variation in gene expression across embryo development stages in Arabidopsis and maize, demonstrating how the PO can be used to compare patterns of expression across stages and in developmentally different species. Although many genes appear to be active throughout embryo development, we identified a small set of uniquely expressed genes for each stage of embryo development and also between the two species. Evaluating the different sets of genes expressed during embryo development in Arabidopsis or maize may inform future studies of the divergent developmental pathways observed in monocotyledonous versus dicotyledonous species. The PO and its annotation databasemake plant data for any species more discoverable and accessible through common formats, thus providing support for applications in plant pathology, image analysis, and comparative development and evolution.

Since the time of Hippocrates, madness has typically been viewed through the lens of disease, dysfunction, and defect. In 'Madness', philosopher of science Justin Garson presents a radically different paradigm for conceiving of madness and the forms that it takes. In this paradigm, which he calls madness-as-strategy, madness is neither a disease nor a defect, but a designed feature, like the heart or lungs.

This paper argues for contrastivism about the deontic modals, 'ought', 'must', and 'may'. A simple contrastivist semantics that predicts the desired entailment relations among these modals is offered.

The Oxford Handbook of Chinese Philosophy is a collection of essays on important texts and figures in the history of Chinese thought. The essays cover both well-known texts such as the Analects and the Zhuangzi as well as many of the lesser-known thinkers in the classical and post-classical Chinese tradition. Most of the chapters focus on thinkers or texts in one of three important historical movements: Classical ("pre-Qin") Chinese philosophy, Chinese Buddhism, and the Confucian response to Buddhism ("neo-Confucianism" broadly construed).

This is a short overview of the biological functions debate in philosophy. While it was fairly comprehensive when it was written, my short book ​A Critical Overview of Biological Functions has largely supplanted it as a definitive and up-to-date overview of the debate, both because the book takes into account new developments since then, and because the length of the book allowed me to go into substantially more detail about existing views.

The downsides of monogamy are felt by most people engaged in long-term relationships, including restrictions on self-discovery, limits on friendship, sexual boredom, and a circumscribed understanding of intimacy. Yet, a "happily ever after" monogamy is assumed to be the ideal form of romantic love in many modern societies: a relationship that is morally ideal and will bring the most happiness to its two partners. -/- In Why It’s OK to Not Be Monogamous, Justin L. Clardy deeply questions these assumptions. (...) He rejects the claim that non-monogamy among honest, informed and consenting adults is morally impermissible. He shows instead how polyamorous relationships can actually be exemplars of moral virtue. The book discusses how social and political forces sustain and reward monogamous relationships. The book defines non-monogamy as a privative concept; a negation of monogamy. Looking at its prevalence in the United States, the book explains how common criticisms of non-monogamy come up short. Clardy argues, as some researchers have recently shown―monogamy relies on continually demonizing non-monogamy to sustain its moral status. Finally, the book concludes with a focus on equality, asking what justice for polyamorous individuals might look like. (shrink)

Most a posteriori arguments against the existence of God take the following form: (1) If God exists, the world would not be like this (where 'this' picks out some feature of the world like the existence of evil, etc.) (2) But the world is like this . (3) Therefore, God does not exist. Skeptical theists are theists who are skeptical of our ability to make judgments of the sort expressed by premise (1). According to skeptical theism, if there were a (...) God, it is likely that he would have reasons for acting that are beyond our ken, and thus we are not justified in making all-things-considered judgments about what the world would be like if there were a God. In particular, the fact that we don't see a good reason for X does not justify the conclusion that there is no good reason for X. 1 Thus, skeptical theism purports to undercut most a posteriori arguments against the existence of God. What follows is an account of the nature of skeptical theism, an application of skeptical theism to both the argument from evil and the argument from divine hiddenness, and a review of the cases for and against skeptical theism.

Leading researchers in the philosophy of mind present and explore cutting edge research in the exciting new field of experimental philosophy.

Both advocates and critics of experimental philosophy often describe it in narrow terms as being the empirical study of people’s intuitions about philosophical cases. This conception corresponds with a narrow origin story for the field—it grew out of a dissatisfaction with the uncritical use of philosophers’ own intuitions as evidence for philosophical claims. In contrast, a growing number of experimental philosophers have explicitly embraced a broad conception of the sub-discipline, which treats it as simply the use of empirical methods to (...) inform philosophical problems. And this conception has a corresponding broad origin story—the field grew out of a recognition that philosophers often make empirical claims and that empirical claims call for empirical support. In this paper, I argue that the broad conception should be accepted, offering support for the broad origin story. (shrink)

Because anticipated and retrospective regret play important roles in practical deliberation and motivation, better understanding them can illuminate the contours of human agency. However, the possibility of self-ignorance and the fact that we change over time can make regret—especially anticipatory regret—not only a poor predictor of where the agent will be in the future but also an unreliable indicator of where the agent stands. Granting these, this paper examines the way in which prospective and, particularly, retrospective regret can nevertheless yield (...) important insight into the sorts of creatures we are, both generally and individually. The experience of retrospective regret can show a person she values something in a way she did not know or that she is (or was) a different person than she had thought, insights which can factor into forward-looking, or prospective, deliberation. Such instances of revelatory regret reveal something to the agent about herself as agent. I examine two cases of agential self-ignorance. In the first, the experience of regret reveals what the agent values, not only to others but even to the agent himself. In the second, the agent anticipates experiencing regret for an action but does not experience the regret, suggesting that the agent did not value the rejected alternative in the way she thought. Anticipatory regret is forward-looking and can play an important role in practical deliberation. But insofar as anticipatory regret flows from one’s imperfect judgment and prospection about oneself, retrospective regret can be an important corrective in helping the agent understand her own standpoint.

A crucial tenet of virtue-based or expertise-based theorizing about politics is that there are ways to identify and select morally and epistemically excellent people to hold office. This paper considers historical challenges to this task that come from within Greek and Confucian thought and political practice. Because of how difficult it is to assess character in ordinary settings, we argue that it is even more difficult to design institutions that select for virtue at the much wider political scale. Specifically, we (...) argue that the vast majority of proposals that purport to select for virtue are either (a) unlikely to be effective, (b) not implementable at the scale of most current nations, or (c) have already been incorporated into most democratic states. Thus defenders of meritocratic institutions should take more seriously the practical barriers that will almost certainly arise when trying to implement these proposals at scale. Historical proponents of meritocratic values were well aware of concerns about the feasibility of their political ideals, and we should be too. (shrink)

This chapter focuses on attributions of phenomenal consciousness, leaving to the side interesting questions about how people attribute other types of consciousness. While researchers are not in perfect agreement about how the concept of phenomenal consciousness should be understood, the standard line is that a creature is phenomenally conscious just in case it has phenomenally conscious mental states, and that a mental state is phenomenally conscious just in case it has phenomenal qualities. The chapter explores whether lay people employ the (...) concept of phenomenal consciousness. It begins by looking at the evidence for an affirmative answer to this question, focusing on Joshua Knobe and Jesse Prinz's article, Intuitions About Consciousness: Experimental Studies. The chapter explains the evidence for a negative answer to the target question, focusing on Justin Sytsma and Edouard machery's article, Two Conceptions of Subjective Experience. (shrink)

Contrastivism about ‘ought’ holds that ‘ought’ claims are relativized, at least implicitly, to sets of mutually exclusive but not necessarily jointly exhaustive alternatives. This kind of theory can solve puzzles that face other linguistic theories of ‘ought’, via the rejection or severe restriction of principles that let us make inferences between ‘ought’ claims. By rejecting or restricting these principles, however, the contrastivist takes on a burden of recapturing acceptable inferences that these principles let us make. This paper investigates the extent (...) to which a contrastivist can do this. (shrink)

In this chapter, I consider two hypotheses that have informed recent work in experimental philosophy of mind. The first is a positive hypothesis put forward by Fiala, Arico, and Nichols : Categorization of an entity as an agent through fast, automatic, and domain-specific processing produces a disposition to ascribe a wide range of mental states to that entity. The second is a negative hypothesis put forward by Sytsma and Machery: The existence of phenomenally conscious mental states is not obvious from (...) first-person experience with states like seeing red and feeling pain. I argue that these hypotheses are not necessary at odds. Despite this, empirical results reported by Sytsma and Machery raise concerns for FAN's hypothesis, while results reported by FAN in response raise concerns for our hypothesis. I address these concerns in this essay, presenting the results of four new studies that support our negative hypothesis against FAN's challenge. (shrink)

Contemporary metaphysics is dominated by the view that every object belongs to a kind permanently in the sense that it cannot cease to belong to that kind without thereby ceasing to exist. For example, some philosophers think that a person is destroyed if they cease to be a person, a statue is destroyed if it ceases to be a statue, and so on. I believe that this standard view is false. Being a person, or a statue, or etc., is like (...) being a child: just as I did not cease to exist when I ceased to be a child, so people and statues need not cease to exist when they cease to be people and statues. Borrowing a term from Daniel Korman (who uses it in a similar but perhaps not identical way), I call this view phasalism because it entails that the kind-properties which ordinary objects instantiate are phase sortal properties, i.e., kind-properties that an object can instantiate for a temporary phase of its career. This dissertation is a partial defense of phasalism. I develop a phasalist metaphysics in detail, highlighting its virtues and rebutting objections along the way. After some stage-setting (Chapter 1), I defend a phasalist criterion of identity over time for ordinary objects (Chapter 2), as well as a phasalist account of the role that sortal properties play in the identity over time of ordinary objects (Chapter 3). Then I defend a phasalist-friendly approach to the identity over time of lumps, hunks, pieces, etc. of matter (Chapter 4). The material in these chapters amounts to a phasalist solution to certain material coincidence puzzles, such as the puzzle of the statue and the piece of clay. I go on to show that familiar puzzles about undetached parts (Chapter 5) and fission (Chapter 6) can be solved within the confines of my phasalist metaphysics as well. (shrink)

Beliefs have genealogies. Can tracing a belief’s genealogy illuminate the epistemic quality of the belief? This paper sets out a general epistemology of genealogies. As it turns out, genealogies for beliefs come in two sorts: those that trace a belief to some mental event that doubles as evidence for the belief and those that do not. The former have the potential to undercut the belief, rebut the belief, or—importantly—both. The latter have the potential to reinforce the belief or rebut the (...) belief but—importantly—not undercut it. The ultimate conclusion is that there is a role for genealogies in the epistemic appraisal of our beliefs, but this role will be circumscribed by the availability of clear and compelling genealogies.

In this paper I argue that when thinking about justice, political philosophers should pay more attention to social norms, not just the usual subjects of basic principles, rights, laws, and policies. I identify two widely-endorsed ideas about political philosophy that interfere with recognizing the importance of social norms—ideas I dub ‘compulsoriness’ and ‘institutionalism’—and argue for their rejection. I do this largely by focusing on questions about who can and should be an agent of justice. I argue that careful reflection on (...) these questions supports a kind of pluralism that reveals the importance of social norms, three types of which I discuss. (shrink)

This work analyses Marx's philosophy of nature and shows how it is the basis for his practical philosophy. Previous analysis of Marx's philosophy of nature has considered humans as only natural beings and social beings. But, Marx analyzed humans' relationship to the natural world and to themselves as natural, social, and material. This material feature of human action can server as a basis for social critique and as the foundation for a practical analysis. The first chapter of this book analyzes (...) Marx's philosophy of nature from his early to late works and argues that humans are natural begins that use nature to develop new capacities. This consideration is central in Marx's critiques of Hegel and Feuerbach. The second chapter discusses Marx's material critique of social forms and discusses why the distinction between material action and social action is a key component of Marx critique of capitalism. This chapter also discusses industrial history, ideology, wages, justice, and valorization. The third and final chapter builds on Marx's materialist analysis to develop a standard of practical action that takes human's material activity as its basis. This chapter also discusses classical historical materialist claims, liberal ethical theories, and a practical philosophic consideration of socialism. (shrink)

The world is an untidy place, and the sciences—all of them—reflect this. One source of this untidiness is the relationship between levels of organization. Reducing macrolevels to microlevels—explaining the former in terms of the latter—has met with successes but has never been the whole story. In the biological sciences, there has been much attention lately to the shortcomings of reductionism on the grounds that (i) it changes the subject rather than explaining, (ii) it leads to a myopically molecular view of (...) the biological world, and (iii) the behavior or behaviors of complex systems are often very poorly predicted based solely on their microproperties. It is just for these reasons that biologists of many stripes have called for a move away from reductionism and toward a new kind of biology for the 21st century. But what shape might this new biology take? (shrink)

Moral luck is a puzzling aspect of our psychology: Why do we punish outcomes that were not intended (i.e. accidents)? Prevailing psychological accounts of moral luck characterize it as an accident or error, stemming either from a re‐evaluation of the agent's mental state or from negative affect aroused by the bad outcome itself. While these models have strong evidence in their favor, neither can account for the unique influence of accidental outcomes on punishment judgments, compared with other categories of moral (...) judgment. Why might punishment be particularly sensitive to moral luck? We suggest that such sensitivity is easily understood from the broader perspective of punishment's ultimate adaptive goal: Changing others’ behavior by exploiting their capacity to learn. This pedagogical perspective accounts for the exceptional influence of outcomes on punitive sentiments and makes predictions for additional moderators of punishment. We review evidence supporting the pedagogical hypothesis of punishment and discuss fruitful directions for future research. (shrink)

Tourism literature has shown there is a disagreement amongst academics conducting tourism research as to whether tourism is an academic community, academic study, and/or academic discipline. These three terms are used loosely and change in meaning depending upon the author, source, context, and discipline of the author(s). The following paper identifies tourism’s current position in academia using these three ideas of academic acceptance as tools to guide the discussion. Also guiding the discussion are ideas from tourism scholars and Kuhn’s ideas (...) of what constitutes a discipline. The discussion leads to a debate about “truths” in tourism research. Recommendations regarding the advancement of tourism in academia via theory construction in the academic field of tourism are presented. (shrink)

A philosphical exploration of perception explores Wittgenstein's work on visual meaning and his analysis of the concept of "seeing.".

This book addresses a longstanding controversy concerning whether Frankfurt cases—thought experiments of a sort devised by Harry Frankfurt—are counterexamples to the principle of alternative possibilities (roughly, the principle that a person is morally responsible for what he did only if he could have avoided doing it). Frankfurt and many others contend that they are, but here it is argued that, far from being counterexamples to the principle, Frankfurt cases actually provide further confirmation of it, a conclusion that has important implications (...) for our understanding of free will and moral responsibility.

In his Enarrationes in Genesin, Martin Luther finds stories of suffering he can ‘hardly read with dry eyes’. Recent scholars attribute profound ethical value to Luther's tears, especially those shed over the suffering of female characters. This article reconsiders the ethical salience of Luther's tears as a demonstration of interpretive empathy by examining his reading of Hagar and its modern reception history. By comparing Luther's reading of the enslaved Hagar to his reading of her master Abraham, it is argued that (...) gender, power and inequality shape the very conditions in which terms like ‘empathy’, ‘charity’ and ‘suspicion’ appear and this, in turn, invites a reconsideration of the ethical responsibilities we incur as we read texts of terror in light of their role in enduring histories of violence.

The most efficient known method for solving certain computational problems is to construct an iterated map whose fixed points are by design the problem's solution. Although the origins of this idea go back at least to Newton, the clearest expression of its logical basis is an example due to Mermin.

This chapter examines the convention concerning the theories of generation and form in the field of natural philosophy in Great Britain during the seventeenth century. It explains that natural philosophers treated the questions of biological generation interchangeably with those coming from chemistry, mineralogy, and meteorology, and considers Antoine Goudin's argument that there are both efficient and final causes at work in the earth's production of rocks that resemble animals or parts of animals. The chapter also suggests that the ‘chymists’ were (...) consistently presented as a challenging third party, alongside Aristotelianism and traditional atomism, in the effort to account for the composition of natural bodies.

In The Sickness unto Death, Kierkegaard describes selfhood as an achievement, specifically claiming that the self’s task ‘is to become itself’ (SUD, 29/SKS 11, 143). But how can one can become who or what one already is, and what sort of achievement is it? This chapter draws on the work of Christine Korsgaard, another philosopher who sees selfhood as an achievement, using her notion of practical identity to explore Kierkegaard’s accounts of the structure of the self and of selfhood as (...) achievement. Kierkegaard’s treatment of selfhood—as aspirational and, if undertaken well, appropriately grounded in one’s facticity (i.e. the concrete facts of one’s situation)—suggests how consciously endorsed identities can guide (or fail to guide) our agency. Having a practical identity involves striving to inhabit adopted roles by aligning our actions with relevant normative demands, but also sometimes embracing and consciously adopting identities already tacitly guiding our engagement with the world. This framework also suggests several ways we can be alienated from desires, actions, or, more generally, our selves. Putting Kierkegaard in conversation with contemporary agency theory, this chapter has two guiding lines of inquiry. First, what does it mean to achieve selfhood and how can the notion of practical identity illuminate or be illuminated by this question? Second, how can this analysis clarify the experience of not being oneself, whether resulting from self-deception, self-ignorance, or the potentially frustrating gap between who one is and who one wants to be?

I develop a reduction of grounding to essence. My approach is to think about the relation between grounding and essence on the model of a certain conceptof existential dependence. I extend this concept of existential dependence in a coupleof ways and argue that these extensions provide a reduction of grounding to essenceif we use sorted variables that range over facts and take it that for a fact to obtain is forit to exist. I then use the account to resolve various (...) issues surrounding the concept of grounding and its connection with essence; apply the account to paradigm cases andto the impure logic of grounding; and respond to objections.

This paper focuses on the concept of collective essence: that some truths are essential to many items taken together. For example, that it is essential to conjunction and negation that they are truth-functionally complete. The concept of collective essence is one of the main innovations of recent work on the theory of essence. In a sense, this innovation is natural, since we make all sorts of plural predications. It stands to reason that there should be a distinction between essential and (...) accidental plural predications if there is a distinction among singular predications. In this paper I defend the view that the concept of collective essence is governed by the principle of Monotonicity: that something is essential to some items only if it is essential to any items to which they belong.

In "Mathematical Truth", Paul Benacerraf articulated an epistemological problem for mathematical realism. His formulation of the problem relied on a causal theory of knowledge which is now widely rejected. But it is generally agreed that Benacerraf was onto a genuine problem for mathematical realism nevertheless. Hartry Field describes it as the problem of explaining the reliability of our mathematical beliefs, realistically construed. In this paper, I argue that the Benacerraf Problem cannot be made out. There simply is no intelligible problem (...) that satisfies all of the constraints which have been placed on the Benacerraf Problem. The point generalizes to all arguments with the structure of the Benacerraf Problem aimed at realism about a domain meeting certain conditions. Such arguments include so-called "Evolutionary Debunking Arguments" aimed at moral realism. I conclude with some suggestions about the relationship between the Benacerraf Problem and the Gettier Problem. (shrink)

It is commonly suggested that evolutionary considerations generate an epistemological challenge for moral realism. At first approximation, the challenge for the moral realist is to explain our having many true moral beliefs, given that those beliefs are the products of evolutionary forces that would be indifferent to the moral truth. An important question surrounding this challenge is the extent to which it generalizes. In particular, it is of interest whether the Evolutionary Challenge for moral realism is equally a challenge for (...) mathematical realism. It is widely thought not to be. In this paper, I argue that the Evolutionary Challenge for moral realism is equally a challenge for mathematical realism. Along the way, I substantially clarify the Evolutionary Challenge, discuss its relation to more familiar epistemological challenges, and broach the problem of moral disagreement. The paper should be of interest to ethicists because it places pressure on anyone who rejects moral realism on the basis of the Evolutionary Challenge to reject mathematical realism as well. And the paper should be of interest to philosophers of mathematics because it presents a new epistemological challenge for mathematical realism that bears, I argue, no simple relation to Paul Benacerraf's familiar challenge.
