My essay addresses the situationist critique of virtue ethics. I defend a rarity of virtue response to this critique, but blunt its tip by developing an account of degrees of virtue. On this account, full virtue will indeed be a statistical rarity, but lesser degrees of virtue more common. I argue for this degreed conception of virtue both on historical and systematic grounds: historically, I show that Aristotle and especially Aquinas thought of virtue as being the sort of property that (...) admits of degrees; and systematically, I draw from recent work in metaphysics on dispositions that challenges a simple counterfactual account of dispositions, and allows for gradable dispositions.

Thomas Aquinas’s thought on how human natural inclinations relate to the cognition of basic human goods has been and continues to be highly disputed. Pointing out the weaknesses of both old and new natural law interpretations, I offer an interpretation that is highly sensitive to Aquinas’s language in key texts on this issue and in addition draws upon texts where Aquinas explicates the relationship between inclination and selective attention. I argue that the natural inclinations primarily play a directive role in (...) drawing an agent’s attention to naturally apprehend basic human goods. This directive role is both externalist and reliabilist—the agent need not be aware of the inclinations and cognitive features that reliably direct her attention. Following a principle he inherits from Aristotle, I claim that for Aquinas, as human beings are by nature, so do the basic human goods seem to them. (shrink)

In this paper, I tackle Aquinas’s notion of ‘natural inclinations’, specifically as it occurs in his seminal elaboration of the natural law in Summa Theologiae I-II. Question 94. Article 2. Maintaining that it constitutes a departure from Aristotle’s terminology, and is hence puzzling, I go on to investigate a raft of modern, mainly Anglophone, interpretations of the concept. Beginning with Jacques Maritain, I move through the broadly chronological sequence of John Finnis, Jean Porter, Steven Jensen, Justin Matchulat and (...) Stephen Brock. In each case, I argue that – despite these scholars’ philosophical ingenuity and textual facility – there are crucial problems with their respective approaches and construals. I end the paper by outlining my own construal of ‘natural inclinations’, which, even if not bolstered by heavy textual scholarship, is at least coherent and, moreover, avoids the philosophical pitfalls of the above interpretations.

Moral grandstanding is a pervasive feature of public discourse. Many of us can likely recognize that we have engaged in grandstanding at one time or another. While there is nothing new about the phenomenon of grandstanding, we think that it has not received the philosophical attention it deserves. In this essay, we provide an account of moral grandstanding as the use of public discourse for moral self-promotion. We then show that our account, with support from some standard theses of social (...) psychology, explains the characteristic ways that grandstanding is manifested in public moral discourse. We conclude by arguing that there are good reasons to think that moral grandstanding is typically morally bad and should be avoided. (shrink)

It is widely agreed that the intelligibility of modal metaphysics has been vindicated. Quine's arguments to the contrary supposedly confused analyticity with metaphysical necessity, and rigid with non-rigid designators.2 But even if modal metaphysics is intelligible, it could be misconceived. It could be that metaphysical necessity is not absolute necessity – the strictest real notion of necessity – and that no proposition of traditional metaphysical interest is necessary in every real sense. If there were nothing otherwise “uniquely metaphysically significant” about (...) metaphysical necessity, then paradigmatic metaphysical necessities would be necessary in one sense of “necessary”, not necessary in another, and that would be it. The question of whether they were necessary simpliciter would be like the question of whether the Parallel Postulate is true simpliciter – understood as a pure mathematical conjecture, rather than as a hypothesis about physical spacetime. In a sense, the latter question has no objective answer. In this article, I argue that paradigmatic questions of modal metaphysics are like the Parallel Postulate question. I then discuss the deflationary ramifications of this argument. I conclude with an alternative conception of the space of possibility. According to this conception, there is no objective boundary between possibility and impossibility. Along the way, I sketch an analogy between modal metaphysics and set theory. (shrink)

Recent work in cognitive science of religion (CSR) is beginning to converge on a very interesting thesis—that, given the ordinary features of human minds operating in typical human environments, we are naturally disposed to believe in the existence of gods, among other religious ideas (e.g., seeAtran [2002], Barrett [2004; 2012], Bering [2011], Boyer [2001], Guthrie [1993], McCauley [2011], Pyysiäinen [2004; 2009]). In this paper, we explore whether such a discovery ultimately helps or hurts the atheist position—whether, for example, it lends (...) credence to atheism by explaining away religious belief or whether it actually strengthens some already powerful arguments against atheism in the relevant philosophical literature.We argue that the recent discoveries of CSR hurt, not help, the atheist position—that CSR, if anything, should not give atheists epistemic assurance.

Reformed epistemology and cognitive science have remarkably converged on belief in God. Reformed epistemology holds that belief in God is basic—that is, belief in God is a natural, non-inferential belief that is immediately produced by a cognitive faculty. Cognitive science of religion also holds that belief in gods is (often) non-reflectively and instinctively produced—that is, non-inferentially and automatically produced by a cognitive faculty or system. But there are differences. In this paper, we will show some remarkable points of convergence, and (...) a few points of divergence, between Reformed epistemology and the cognitive science of religion. (shrink)

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 four experiments presented support Boyer's theory that counterintuitive concepts have transmission advantages that account for the commonness and ease of communicating many non-natural cultural concepts. In Experiment 1, 48 American college students recalled expectation-violating items from culturally unfamiliar folk stories better than more mundane items in the stories. In Experiment 2, 52 American college students in a modified serial reproduction task transmitted expectation-violating items in a written narrative more successfully than bizarre or common items. In Experiments 3 and 4, (...) these findings were replicated with orally presented and transmitted stimuli, and found to persist even after three months. To sum, concepts with single expectation-violating features were more successfully transmitted than concepts that were entirely congruent with category-level expectations, even if they were highly unusual or bizarre. This transmission advantage for counterintuitive concepts may explain, in part, why such concepts are so prevalent across cultures and so readily spread. (shrink)

We identify a novel ‘cultural red king effect’ that, in many cases, results in stable arrangements which are to the detriment of minority groups. In particular, we show inequalities disadvantaging minority groups can naturally arise under an adaptive process when minority and majority members must routinely determine how to divide resources amongst themselves. We contend that these results show how inequalities disadvantaging minorities can likely arise by dint of their relative size and need not be a result of either explicit (...) nor implicit prejudices, nor due to intrinsic differences between minority and majority members.

In this paper we use an experimental approach to investigate how linguistic conventions can emerge in a society without explicit agreement. As a starting point we consider the signaling game introduced by Lewis. We find that in experimental settings, small groups can quickly develop conventions of signal meaning in these games. We also investigate versions of the game where the theoretical literature indicates that meaning will be less likely to arise—when there are more than two states for actors to transfer (...) meaning about and when some states are more likely than others. In these cases, we find that actors are less likely to arrive at strategies where signals have clear conventional meaning. We conclude with a proposal for extending the use of the methodology of experimental economics in experimental philosophy. (shrink)

The revival of virtue ethics over the last thirty‐five years has produced a bewildering diversity of theories, which on the face of it seem united only by their opposition to various features of more familiar Kantian and Utilitarian ethical theories. In this paper I present a systematic account of the main positive features of virtue ethics, by articulating the common ground shared by its different varieties. I do so not to offer a fresh defence of virtue ethics, but rather to (...) provide a conceptual map that locates its main claims and arguments in relation to those of rival theories, and identifies its distinctive contribution to contemporary ethics. I set out six specific claims which are made by all forms of virtue ethics, and I explain how these claims distinguish the theory from recent character‐based forms of Kantian ethics and Utilitarianism. I then use this framework to briefly survey two main strands of virtue ethics which have been developed in the literature.1. (shrink)

This essay* takes two notions of autonomy and two notions of explanation and argues that colours occur in explanations that fall under all of them. The claim that colours can be used to explain anything at all may seem to some people an outrage. But their pessimism is unjustified and the orthodox dispositional view which may seem to support it, I shall argue, itself has difficulties. In broad terms, Section 2 shows that there exist good straight scientific laws of colour, (...) constituting what one might call a phenomenal science. Section 3 offers a larger view of what we are doing when we attribute colours to things, a view which makes it a case of holistic explanation, similar in many ways to psychological explanation. Section 2 emphasizes the model of scientific explanation, and Section 3 the holistic model found in rational explanation; but it will emerge that colour explanation in different ways fits both models, as it also does the two principal notions of autonomy that the first section identifies.

This work draws an analogical defence of strong emotionism—the metaethical claim that moral properties and concepts consist in the propensity of actions to elicit emotional responses from divergent emotional perspectives. I offer a theory that is in line with that of Prinz. I build an analogy between moral properties and what I call emotion-dispositional properties. These properties are picked out by predicates such as ‘annoying’, ‘frightening’ or ‘deplorable’ and appear to be uncontroversial and frequent cases of attribution error—the attributing of (...) subjective emotional states as mind-independent properties. I present a linguistic analysis supporting the claim that moral properties and their related concepts are reducible to a subset of emotion-dispositional properties and concepts. This is grounded in the observation that utterances featuring moral predicates function linguistically and conceptually in analogous ways to emotion-dispositional predicates. It follows from this view that asserted moral utterances are truth-apt relative to ethical communities, but that speakers misconceive the extensions of predicates. I show how the framework of Cognitive Linguistics allows us to explain this error. Further analysis of moral and non-moral utterances exposes the deeper conceptual schemas structuring language through cognitive construal processes. An understanding of these processes, coupled with an emotionist elucidation of moral properties and concepts, makes the attribution error an expected upshot of the emotionist thesis, rather than an uncomfortable consequence.

What is it to blame someone, and when are would-be blamers in a position to do so? What function does blame serve in our lives, and is it a valuable way of relating to one another? The essays in this volume explore answers to these and related questions.

Collaboration is increasingly popular across academia. Collaborative work raises certain ethical questions, however. How will the fruits of collaboration be divided? How will the work for the collaborative project be split? In this paper, we consider the following question in particular. Are there ways in which these divisions systematically disadvantage certain groups? -/- We use evolutionary game theoretic models to address this question. First, we discuss results from O'Connor and Bruner (unpublished). In this paper, we show that underrepresented groups in (...) academia can be disadvantaged in such situations by dint of their small numbers. Second, we present novel results exploring how the hierarchical structure of academia can lead to bargaining disadvantage. We investigate models where one actor has a higher baseline of academic success, less to lose if collaboration goes south, or greater rewards for non-collaborative work. We show that in these situations, the less powerful partner is disadvantaged in bargaining over collaboration. (shrink)

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)

Social contract theorists often take the ideal contract to be the agreement or bargain individuals would make in some privileged choice situation. Recently, experimental philosophers have explored this kind of decision-making in the lab. One rather robust finding is that the exact circumstances of choice significantly affect the kinds of social arrangements experimental subjects unanimously endorse. Yet prior work has largely ignored the question of which of the many competing descriptions of the original position subjects find most compelling. This paper (...) aims to address this gap, exploring how attractive experimental subjects find various characterizations of these circumstances of choice. We find evidence suggesting that no one choice situation can fulfill the role that social contract theorists have hoped it would play. We also find that, contrary to what some prominent social contract theorists have expected, there is no robust relationship between an individual’s ranking of distributive principles and their ranking of various descriptions of the original position. In conclusion, we discuss the broader implications of these results for political philosophy. (shrink)

Lawson and McCauley have argued that non-cultural regularities in how actions are conceptualized inform and constrain participants' understandings of religious rituals. This theory of ritual competence generates three predictions: 1) People with little or no knowledge of any given ritual system will have intuitions about the potential effectiveness of a ritual given minimal information about the structure of the ritual. 2) The representation of superhuman agency in the action structure will be considered the most important factor contributing to effectiveness. 3) (...) Having an appropriate intentional agent initiate the action will be considered relatively more important than any specific action to be performed. These three predictions were tested in two experiments with 128 North American Protestant college students who rated the probability of various fictitious rituals to be effective in bringing about a specified consequence. Results support Lawson and McCauley's predictions and suggest that expectations regarding ordinary social actions apply to religious rituals. (shrink)

For epistemic subjects like us, updating our credences incurs epistemic costs. Expending our limited processing power and working memory to properly update our credences by some information can come at the cost of not responding to other available information. It is thus desirable to flesh out and compare alternative ways of taking information into account in light of cognitive shortcomings like our own. This paper is a preliminary attempt to do so. I argue that it is better, in a range (...) of circumstances and from the point of view of expected credal accuracy, for epistemic subjects like us not to update on available information that bears on propositions for which substantial evidence has been gathered than it is to update on information as it presents itself. In order to clarify the argument, and enable comparisons between information-response policies more generally, I develop a queue-theoretic model of learning for subjects with cognitive limitations. The model characterizes how policies for responding to information interact with a subject’s limitations to yield confidences. Finally, I discuss implications of the discussion for work on confidence, outright belief, and the relationship between those two states. The comparison of information-response policies helps to explain how some of the “biases” revealed by psychological research might be cognitively valuable, clarify views that take outright belief to be a kind of epistemic plan that resists reconsideration, and assuage certain “demandingness” worries for the hypothesis that we are credal reasoners.

It is not uncommon to find assumptions being made about folk psychology in the discussions of phenomenal consciousness in philosophy of mind. In this article I consider one example, focusing on what Dan Dennett says about the 'folk theory of consciousness'. I show that he holds that the folk believe that qualities like colours that we are acquainted with in ordinary perception are phenomenal qualities. Nonetheless, the shape of the folk theory is an empirical matter and in the absence of (...) empirical investigation there is ample room for doubt. Fortunately, experimental evidence on the topic is now being produced by experimental philosophers and psychologists. This article contributes to this growing literature, presenting the results of six new studies on the folk view of colours and pains. I argue that the results indicate against Dennett's theory of the folk theory of consciousness. (shrink)

I examine how particular social arrangements and incentive structures encourage the honest reporting of experimental results and minimize fraudulent scientific work. In particular I investigate how epistemic communities can achieve this goal by promoting members to police the community.

I find that this system of peer policing can in many cases ensure (...) high levels of honesty. (shrink)

The present study sought to determine whether Barrett's counterintuitiveness coding and quantifying scheme could be applied to cultural materials with sufficient intercoder reliability, provide evidence concerning just how counterintuitive is too counterintuitive for a concept to be a recurrent cultural idea, and test whether counterintuitive intentional agent concepts are more common in folktales than other classes of counterintuitive concepts. Seventy-three folktales from around the world were sampled from larger collections. Using Barrett's CI-Scheme, two independent coders identified 116 counterintuitive objects and (...) scored them for degree of counterintuitiveness with very high inter-rater concordance. Of folktales, 79% had one or two counterintuitive objects. Of the counterintuitive objects 93% had a counterintuitiveness score of only one. Of counterintuitive objects, 98% were agents. Results suggest the CI-Scheme may have utility for analyzing cultural materials, that the cognitive optimum for cultural transmission falls around one counterintuitive feature, and that counterintuitive agents are more common than other types of counterintuitive objects in folktales.

Public health ethicists face two difficult questions. First, what makes something a matter of public health? While protecting citizens from outbreaks of communicable diseases is clearly a matter of public health, is the same true of policies that aim to reduce obesity, gun violence or political corruption? Second, what should the scope of the government’s authority be in promoting public health? May government enact public health policies some citizens reasonably object to or policies that are paternalistic? Recently, some theorists have (...) attempted to address these questions by arguing that something is a matter of public health if and only if it involves a health-related public good, such as clean water or herd immunity. Relatedly, they have argued that appeals to the promotion of public health should only be used to justify the provision of health-related public goods. This public goods conception of public health (PGC) is meant to enjoy advantages over its rivals in three respects: it provides a better definition of public health than rival views, it respects moral disagreement, and it avoids licensing objectionably paternalistic public health policies. We argue, however, that the PGC does just as poorly, or worse, than its rivals in all three respects. (shrink)

The world’s leading environmental advisory institutions look to ecological theory and research as an objective guide for policy and resource management decision-making. In addition to various theoretical merits of doing so, it is therefore crucially important to clear up confusions about ecology’s conceptual foundations and to make plain the basic workings of inferential methods used in the science. Through discussion of key moments in the genesis of the theoretical branch of ecology, this essay elucidates a general heuristic role of teleological (...) metaphor in ecological research and defuses certain enduring confusions and misguided criticisms of current work in ecology.

I outline a theory of moral motivation which is compatible with the metaphysical claims of strong emotionism—a sentimentalist account of morality first outlined by Jesse Prinz and supported by myself which construes moral concepts and properties as a subset of emotion-dispositional properties. Given these claims, it follows that sincere moral judgements are necessarily motivating in virtue of their emotional constitution. I defend an indefeasible version of judgement motivational internalism which takes into consideration both positively and negatively valenced affective states and (...) how they promote both approach and avoidance motivation, respectively. On this view, in making sincere moral judgements agents are antecedently motivated by standing Desires to avoid or approach the stimuli picked out by their judgements. I also defend internalism against the objections from defeating circumstances and amoralists. As regards the former, I claim that the tendency of philosophers to frame the motivation debate in terms of positive moral judgements makes the argument from defeating circumstances appear more plausible than it is; as regards the latter, I claim the amoralist argument only has force if it is empirically well supported and that psychological data has hitherto been unconvincing.

More and more businesses are aligning their activities with the principles of sustainable development. Therefore they need to adapt their ways of measuring corporate performance. However, it includes issues which may be outside the direct control of the organisation, that are difficult to characterise and often are based on value judgements rather than hard data. The difficulty in measuring performance is further complicated by the fact that many corporations have a complex organisational structure, with different business streams, functions and projects.

This paper has used two case studies to explore how the appropriate use of indicators can be a powerful tool in addressing the sustainability of businesses both at a corporate wide level and at a project level.

In recent years methodological debates in the social sciences have increasingly focused on issues relating to epistemology. Realism and Sociology makes an original contribution to the debate, charting a middle ground between postmodernism and positivism.

Christian Protestants typically affirm both the essential moral perfection of heaven and the sufficiency of saving faith. Yet these two commitments generatean apparently self-destructive dilemma—one I call the dilemma of sanctification. The prima facie puzzle can be resolved in at least three ways. In this paper, I articulate the dilemma of sanctification in some detail and offer an argument against a widely-held Protestant solution I call provisionism. This constitutes indirect support for the solution I find most promising, namely, a doctrine (...) of purgatory. I close by sketching a model of purgatory consistent with Protestant soteriology.

Recently, philosophers have drawn on tools from game theory to explore behavior in Hobbes’ state of nature. I take a similar approach and argue the Lockean state of nature is best conceived of as a conflictual coordination game. I also discuss Nozick’s famous claim regarding the emergence of the state and argue the path to the minimal state is blocked by a hitherto unnoticed free-rider problem. Finally, I argue that on my representation of the Lockean state of nature both widespread (...) conflict and lasting peace are possible. This, I contend, is in line with one popular interpretation of Locke. (shrink)

Iris Murdoch was a notable philosopher before she was a notable novelist and her work was brave, brilliant, and independent. She made her name first for her challenges to Gilbert Ryle and behaviourism, and later for her book on Sartre, but she had the greatest impact with her work in moral philosophy—and especially her book The Sovereignty of Good. She turned expectantly from British linguistic philosophy to continental existentialism, but was dissatisfied there too; she devised a philosophy and a style (...) of philosophy that were distinctively her own. Murdoch aimed to draw out the implications, for metaphysics and the conception of the world, of rejecting the standard dichotomy of language into the 'descriptive' and the 'emotive'. She aimed, in Wittgensteinian spirit, to describe the phenomena of moral thinking more accurately than the 'linguistic behaviourists' like R. M. Hare. This 'empiricist' task could be acheived, Murdoch thought, only with help from the idealist tradition of Kant, Hegel, and Bradley. And she combined with this a moral psychology, or theory of motivation, that went back to Plato, but was influenced by Freud and Simone Weil. Murdoch's impact can be seen in the moral philosophy of John McDowell and, in different ways, in Richard Rorty and Charles Taylor, as well as in the recent movements under the headings of moral realism, particularism, moral perception, and virtue theory. This volume brings together essays by critics and admirers of Murdoch's work, and includes a longer Introduction on Murdoch's career, reception, and achievement. It also contains a previously unpublished chapter from the book on Heidegger that Murdoch had been working on shortly before her death, and a Memoir by her husband John Bayley. It gives not only an introduction to Murdoch's important philosophical life and work, but also a picture of British philosophy in one of its heydays and at an important moment of transition.Readership: Students and scholars of philosophy and literature.

Through the lenses of cognitive science of religion, successful god concepts must possess a number of features. God concepts must be counterintuitive, an intentional agent, possessing strategic information, able to act in the human world in detectable ways and capable of motivating behaviors that reinforce belief.

Nevertheless, Santa concepts approximate a successful god concept (...) more closely than other widespread cultural characters such as Mickey Mouse and the Tooth Fairy, in part explaining Santa's relative cultural prominence.

Three distinct reasons that Plato calls the rational part of the soul “divine” are analyzed: its metaphysical kinship with the Forms, its epistemological ability to know the Forms, and its ethical capacity to live by them. Supposing these three divine aspects of the rational part are unified in the life of each person, they naturally suggest a process of divinization or “becoming like god” according to which a person, by living more virtuously, which requires increasingly better knowledge of the Forms, (...) gradually becomes united with them. This process of divinization is in fact found throughout the middle and late dialogues, including the Phaedo, Republic, Symposium, Phaedrus, Timaeus, and the Laws. This synoptic view of the Platonic idea of divinization provides a standard according to which misplaced emphasis, flaws, and tension created by other interpretations are criticized and corrected.

Vanderschraaf’s discussion of the egalitarian solution invokes three arguments typically given to support the Nash bargaining solution.

Philosophers and social scientists have recently turned to game theory and agent-based models to better understand social contract formation. The stag hunt game is an idealization of social contract formation. Using the stag hunt game, we attempt to determine what, if any, barrier diversity is to the formation of an efficient social contract. We uncover a deep connection between tolerance, diversity, and the social contract. We investigate a simple model in which individuals possess salient traits and behave cooperatively when the (...) difference between their trait and the trait of their counterpart is less than their ‘tolerance level’. If traits are fixed and correspond to permanent or semipermanent features of the individual, such as religion or race, social contract formation is a remote possibility. If traits are malleable, social contract formation is possible but comes at the steep cost of diversity and tolerance, that is, individuals are unwilling to cooperate with those much different from themselves. Yet homogeneity and intolerance are not a long-term feature of the population. Over time mutations allow for increasingly tolerant agents to prosper, thereby ushering in trait diversity. In the end, all reap the benefits of cooperation. (shrink)

In sketching a preliminary scientific theory of religion, Atran & Norenzayan (A&N) generally agree with cognitive scientists of religion in the factors that coalesce to form religion.

Recently, philosophers have investigated the emergence and evolution of the social contract. Yet extant work is limited as it focuses on the use of simple behavioral norms in rather rigid strategic settings. Drawing on axiomatic bargaining theory, we explore the dynamics of more sophisticated norms capable of guiding behavior in a wide range of scenarios. Overall, our investigation suggests the utilitarian bargaining solution has a privileged status as it has certain stability properties other social arrangements lack.

Inclusive fitness has been under intense scrutiny in recent years, with many critics claiming the framework leads to incorrect predictions. We consider one particularly influential heuristic for estimating inclusive fitness in the context of the very case that motivated reliance on it to begin with: the Sir Philip Sidney signalling game played with relatives. Using a neighbour-modulated fitness model, we show when and why this heuristic is problematic. We argue that reliance on the heuristic rests on a misunderstanding of what (...) it means for two organisms to be related and perpetuates a mischaracterization of the role of the ‘relatedness’ parameter in inclusive fitness. _1_ Introduction _2_ Heuristic Inclusive Fitness _3_ The Sir Philip Sidney Game _4_ Model _5_ Results _6_ Conclusion Appendix.

The categorial concepts of substance (thing) and substance (stuff) are described, and the conceptual relationships between things and their constitutive stuff delineated. The relationship between substance concepts, expressed by other count-nouns, and natural kind concepts is examined. Artefacts and their parts are argued to be substances, whereas parts of organisms are not. The confusions of seventeenth- and eighteenth-century philosophers who invoked the concept of substance are adumbrated.
