It is widely alleged that metaphysical possibility is “absolute” possibility Conceivability and possibility, Clarendon, Oxford, 2002, p 16; Stalnaker, in: Stalnaker Ways a world might be: metaphysical and anti-metaphysical essays, Oxford University Press, Oxford, 2003, pp 201–215; Williamson in Can J Philos 46:453–492, 2016). Kripke calls metaphysical necessity “necessity in the highest degree”. Van Inwagen claims that if P is metaphysically possible, then it is possible “tout court. Possible simpliciter. Possible period…. possib without qualification.” And Stalnaker writes, “we can agree (...) with Frank Jackson, David Chalmers, Saul Kripke, David Lewis, and most others who allow themselves to talk about possible worlds at all, that metaphysical necessity is necessity in the widest sense.” What exactly does the thesis that metaphysical possibility is absolute amount to? Is it true? In this article, I argue that, assuming that the thesis is not merely terminological, and lacking in any metaphysical interest, it is an article of faith. I conclude with the suggestion that metaphysical possibility may lack the metaphysical significance that is widely attributed to it. (shrink)

I discuss methodology in epistemology. I argue that settling the facts, even the epistemic facts, fails to settle the questions of intellectual policy at the center of our epistemic lives. An upshot is that the standard methodology of analyzing concepts like knowledge, justification, rationality, and so on is misconceived. More generally, any epistemic method that seeks to issue in intellectual policy by settling the facts, whether by way of abductive theorizing or empirical investigation, no matter how reliable, is inapt. The (...) argument is a radicalization of Moore’s Open Question Argument. I conclude by considering the ramifications of this conclusion for the debate surrounding “Modal Security”, a proposed necessary condition on undermining defeat. (shrink)

In his précis of a recent book, Richard Joyce writes, “My contention…is that…any epistemological benefit-of-the-doubt that might have been extended to moral beliefs…will be neutralized by the availability of an empirically confirmed moral genealogy that nowhere…presupposes their truth.” Such reasoning – falling under the heading “Genealogical Debunking Arguments” – is now commonplace. But how might “the availability of an empirically confirmed moral genealogy that nowhere… presupposes” the truth of our moral beliefs “neutralize” whatever “epistemological benefit-of-the-doubt that might have been extended (...) to” them? In this article, I argue that there appears to be no satisfactory answer to this question. The problem is quite general, applying to all arguments with the structure of Genealogical Debunking Arguments aimed at realism about a domain meeting two conditions. The Benacerraf-Field Challenge for mathematical realism affords an important special case. (shrink)

In his influential book, The Nature of Morality, Gilbert Harman writes: “In explaining the observations that support a physical theory, scientists typically appeal to mathematical principles. On the other hand, one never seems to need to appeal in this way to moral principles.” What is the epistemological relevance of this contrast, if genuine? This chapter argues that ethicists and philosophers of mathematics have misunderstood it. They have confused what the chapter calls the justificatory challenge for realism about an area, D—the (...) challenge to justify our D-beliefs—with the reliability challenge for D-realism—the challenge to explain the reliability of our D-beliefs. Harman’s contrast is relevant to the first, but not, evidently, to the second. One upshot of the discussion is that genealogical debunking arguments are fallacious. Another is that indispensability considerations cannot answer the Benacerraf–Field challenge for mathematical realism. (shrink)

Set-theoretic pluralism is an increasingly influential position in the philosophy of set theory (Balaguer [1998], Linksy and Zalta [1995], Hamkins [2012]). There is considerable room for debate about how best to formulate set-theoretic pluralism, and even about whether the view is coherent. But there is widespread agreement as to what there is to recommend the view (given that it can be formulated coherently). Unlike set-theoretic universalism, set-theoretic pluralism affords an answer to Benacerraf’s epistemological challenge. The purpose of this paper is (...) to determine what Benacerraf’s challenge could be such that this view is warranted. I argue that it could not be any of the challenges with which it has been traditionally identified by its advocates, like of Benacerraf and Field. Not only are none of the challenges easier for the pluralist to meet. None satisfies a key constraint that has been placed on Benacerraf’s challenge. However, I argue that Benacerraf’s challenge could be the challenge to show that our set-theoretic beliefs are safe – i.e., to show that we could not have easily had false ones. Whether the pluralist is, in fact, better positioned to show that our set-theoretic beliefs are safe turns on a broadly empirical conjecture which is outstanding. If this conjecture proves to be false, then it is unclear what the epistemological argument for set-theoretic pluralism is supposed to be. (shrink)

It is often supposed that, unlike typical axioms of mathematics, the Continuum Hypothesis (CH) is indeterminate. This position is normally defended on the ground that the CH is undecidable in a way that typical axioms are not. Call this kind of undecidability “absolute undecidability”. In this paper, I seek to understand what absolute undecidability could be such that one might hope to establish that (a) CH is absolutely undecidable, (b) typical axioms are not absolutely undecidable, and (c) if a mathematical (...) hypothesis is absolutely undecidable, then it is indeterminate. I shall argue that on no understanding of absolute undecidability could one hope to establish all of (a)–(c). However, I will identify one understanding of absolute undecidability on which one might hope to establish both (a) and (c) to the exclusion of (b). This suggests that a new style of mathematical antirealism deserves attention—one that does not depend on familiar epistemological or ontological concerns. The key idea behind this view is that typical mathematical hypotheses are indeterminate because they are relevantly similar to CH. (shrink)

Holly Smith has done more than anyone to explore and defend the importance of usability for moral theories. In Making Morality Work, she develops a moral theory that is almost universally usable. But not quite. In this article, I argue that no moral theory is universally usable, in the sense that is most immediately relevant to action, even by agents who know all the normative facts. There is no moral theory knowledge of which suffices to settle deliberation about what to (...) do. However, this is unsurprising if the question of what to do is not a question of fact. One upshot of the discussion is that the search for a universally usable moral theory is misconceived. Another is that, contra Smith (341), agents who are radically uncertain need not lack autonomy.

In “Mathematical Truth,” Paul Benacerraf presented an epistemological problem for mathematical realism.

How do axioms, or first principles, in ethics compare to those in mathematics? In this companion piece to G.C. Field's 1931 "On the Role of Definition in Ethics", I argue that there are similarities between the cases. However, these are premised on an assumption which can be questioned, and which highlights the peculiarity of normative inquiry.

Logical monism is the view that there is ‘One True Logic’. This is the default position, against which pluralists react. If there were not ‘One True Logic’, it is hard to see how there could be one true theory of anything. A theory is closed under a logic! But what is logical monism? In this article, I consider semantic, logical, modal, scientific, and metaphysical proposals. I argue that, on no ‘factualist’ analysis (according to which ‘there is One True Logic’ expresses (...) a factual claim, rather than an attitude like approval), does the doctrine have both metaphysical and methodological import. Metaphysically, logics abound. Methodologically, what to infer from what is not settled by the facts, even the normative ones. I conclude that the only interesting sense in which there could be One True Logic is noncognitive. The same may be true of monism about normative areas, like moral, epistemic, and prudential ones, generally. (shrink)

I discuss the structure of genealogical debunking arguments. I argue that they undermine our mathematical beliefs if they undermine our moral beliefs. The contrary appearance stems from a confusion of arithmetic truths with (first-order) logical truths, or from a confusion of reliability with justification. I conclude with a discussion of the cogency of debunking arguments, in light of the above. Their cogency depends on whether information can undermine all of our beliefs of a kind, F, without giving us direct reason (...) to doubt that our F-beliefs are modally secure. (shrink)

I this article, I introduce the notion of pluralism about an area, and use it to argue that the questions at the center of our normative lives are not settled by the facts -- even the normative facts. One upshot of the discussion is that the concepts of realism and objectivity, which are widely identified, are actually in tension. Another is that the concept of objectivity, not realism, should take center stage.

The motivating question of this paper is: ‘How are our beliefs in the theorems of mathematics justified?’ This is distinguished from the question ‘How are our mathematical beliefs reliably true?’ We examine an influential answer, outlined by Russell, championed by Gödel, and developed by those searching for new axioms to settle undecidables, that our mathematical beliefs are justified by ‘intuitions’, as our scientific beliefs are justified by observations. On this view, axioms are analogous to laws of nature. They are postulated (...) to best systematize the data to be explained. We argue that there is a decisive difference between the cases. There is agreement on the data to be systematized in the scientific case that has no analog in the mathematical one. There is virtual consensus over observations, but conspicuous dispute over intuitions. In this respect, mathematics more closely resembles stereotypical philosophy. We conclude by distinguishing two ideas that have long been associated -- realism (the idea that there is an independent reality) and objectivity (the idea that in a disagreement, only one of us can be right). We argue that, while realism is true of mathematics and philosophy, these domains fail to be objective. One upshot of the discussion is that even questions of fundamental physics may fail to be objective in roughly the sense that the question, ‘Is the Parallel Postulate is true?’, understood as one of pure mathematics, fails to be. Another is a kind of pragmatism. Factual questions in mathematics, modality, logic, and evaluative areas go proxy for non-factual practical ones. -/- . (shrink)

I discuss Benacerraf's epistemological challenge for realism about areas like mathematics, metalogic, and modality, and describe the pluralist response to it. I explain why normative pluralism is peculiarly unsatisfactory, and use this explanation to formulate a radicalization of Moore's Open Question Argument. According to the argument, the facts -- even the normative facts -- fail to settle the practical questions at the center of our normative lives. One lesson is that the concepts of realism and objectivity, which are widely identified, (...) are actually in tension. (shrink)

Addicts are often portrayed as compelled by their addiction and thus as a paradigm of unfree action and mitigated blame. This chapter argues that our best scientific theories of addiction reveal that, psychologically, addicts are not categorically different from non-addicts. There is no pairing of contemporary accounts of addiction and of prominent theories of moral responsibility that can justify our intuitions about the mitigation of addicts but not non-addicts. Two conclusions are advanced. First, we should either treat addicts as we (...) normally treat non-addicts (as fully culpable) or embrace the skeptical conclusion that everyone is less responsible than we thought—perhaps not responsible at all. Second, we should be doubtful that theorizing about responsibility will be advanced by focusing on particular kinds of psychopathologies. (shrink)

In Morality & Mathematics, Justin Clarke-Doane argues that it is hard to imagine being "a realist about, for example, the standard model of particle physics, but not about mathematics." I try to explain how that seems very possible from the perspective of a physicist. What is real is the physical world; mathematics starts from descriptions of the natural world and extrapolates from there, but that extrapolation does not imply any independent reality. -/- Submitted to an Analysis Reviews symposium on (...) Clarke-Doane's Morality & Mathematics. (shrink)

A belief one has is safe if either (i) it could not easily be false or (ii) in any nearby world in which it is false, it is not formed using the method one uses to form one’s actual belief. It seems our mathematical beliefs are safe if mathematical pluralism is true: if, loosely put, almost any consistent mathematical theory is true. It seems, after all, that in any nearby world where one’s mathematical beliefs differ from one’s actual beliefs, one (...) would believe some other true, consistent theory. Focusing on Justin Clarke-Doane’s recent discussion, I argue the thesis that mathematical beliefs are safe given pluralism faces some obstacles. I argue (i) is true of mathematical belief given pluralism only if we deny plausible claims about the interpretation of non-pluralists who many of us could easily be. Unless strong metasemantic theses are true, it is plausible many of us could easily deny or refuse to believe a consistent and true mathematical theory we actually believe. Since philosophical arguments and controversies permeate the methodology of foundational mathematics, I argue we cannot confidently distinguish the methods we use in mathematics between worlds, thus raising doubts about (ii). (shrink)

There are many domains about which we think we are reliable. When there is prima facie reason to believe that there is no satisfying explanation of our reliability about a domain given our background views about the world, this generates a challenge to our reliability about the domain or to our background views. This is what is often called the reliability challenge for the domain. In previous work, I discussed the reliability challenges for logic and for deductive inference. I argued (...) for four main claims: First, there are reliability challenges for logic and for deduction. Second, these reliability challenges cannot be answered merely by providing an explanation of how it is that we have the logical beliefs and employ the deductive rules that we do. Third, we can explain our reliability about logic by appealing to our reliability about deduction. Fourth, there is a good prospect for providing an evolutionary explanation of the reliability of our deductive reasoning. In recent years, a number of arguments have appeared in the literature that can be applied against one or more of these four theses. In this paper, I respond to some of these arguments. In particular, I discuss arguments by Paul Horwich, Jack Woods, Dan Baras, Justin Clarke-Doane, and Hartry Field. (shrink)

The fourteen papers in this collection offer a variety of original contributions to the epistemology of modality. In seeking to explain how we might account for our knowledge of possibility and necessity, they raise some novel questions, develop some unfamiliar theoretical perspectives, and make some intriguing proposals. Collectively, they advance our understanding of the field. In Part I of this Introduction, I give some general background about the contemporary literature in the area, by sketching a timeline of the main tendencies (...) of the past twenty-five years or so, up to the present debates. Next, I focus on four features that largely characterize the latest literature, and the papers in the present collection in particular: (i) an endorsement of the importance of essentialism; (ii) a shift to a “metaphysics-first” approach to modal epistemology; (iii) a focus on metaphysical modality as opposed to other kinds of modality; and (iv) a preference for non-uniform modal epistemology. In Part II, I present the individual papers in the volume. These are organized around the following four chapters, based on their topic: (A) Skepticism & Deflationism; (B) Essentialism; (C) Non-Essentialist Accounts; (D) Applications. -/- LIST OF CONTRIBUTORS: Francesco Berto; Stephen Biggs & Jessica Wilson; Justin Clark-Doane; Philip Goff; Bob Hale; Frank Jackson; Mark Jago; Boris Kment; Antonella Mallozzi; Graham Priest; Gabriel Rabin; Amie Thomasson; Anand Vaidya & Michael Wallner; Jennifer Wang. -/- The volume is dedicated to the memory of Bob Hale. -/- .

According to principles of modal security, evidence undermines a belief only when it calls into question certain purportedly important modal connections between one’s beliefs and the truth (e.g., safety or sensitivity). Justin Clarke-Doane and Dan Baras have advanced such principles with the aim of blocking evolutionary moral debunking arguments. We examine a variety of different principles of modal security, showing that some of these are too strong, failing to accommodate clear cases of undermining, while others are too weak, failing (...) to do their advertised work of blocking evolutionary moral debunking arguments. If there is a security principle that slips between the horns of this dilemma—one that is both viable and debunker-blocking—it remains to be formulated. (shrink)

Modalists think that knowledge requires forming your belief in a “modally stable” way: using a method that wouldn't easily go wrong, or using a method that wouldn't have given you this belief had it been false. Recent Modalist projects from Justin Clarke-Doane and Dan Baras defend a principle they call “Modal Security,” roughly: if evidence undermines your belief, then it must give you a reason to doubt the safety or sensitivity of your belief. Another recent Modalist project from Carlotta (...) Pavese and Bob Beddor defends “Modal Virtue Epistemology”: knowledge is a belief that is maximally modally robust across “normal” worlds. We'll offer new objections to these recent Modalist projects. We will then argue for a rival view, Explanationism: knowing something is believing it because it's true. We will show how Explanationism offers a better account of undermining defeaters than Modalism, and a better account of knowledge. (shrink)

Justin Barrett and Kelly James Clark have suggested that cognitive science of religion supports the existence of a god-faculty akin to sensus divinitatis. They propose that God may have given rise to the god-faculty via guided evolution. This suggestion raises two theological worries. First, our natural cognition seems to favor false god-beliefs over true ones. Second, it also makes us prone to tribalism. If God hates idolatry and moral evil, why would he give rise to mind with such (...) biases? A Plantingian response would point to the noetic effects of sin. Such a response, however, would have to assume that God is restoring the minds of believers. This paper considers empirical reasons to doubt that such a process is taking place. (shrink)

In his recent critical notice of The Bounds of Cognition in this journal, Justin Fisher advances a set of concerns that favor the hypothesis that, under certain circumstances, cognitive processes span the brain, body, and world. One is that it is too much to require that representations in cognitive process must have non-derived content. A second is that it is possible that extended objects bear non-derived content. A third is that extended cognition might advocate the extension of certain general (...) categories of cognition. A fourth is that Bounds misapplies Andy Clark and David Chalmers’ so-called “parity principle.” The purpose of this rejoinder is to show how Fisher’s concerns can be, or have already been, addressed.

It is widely acknowledged that the new emerging discipline cognitive science of religion has a bearing on how to think about the epistemic status of religious beliefs. Both defenders and opponents of the rationality of religious belief have used cognitive theories of religion to argue for their point. This paper will look at the defender-side of the debate. I will discuss an often used argument in favor of the trustworthiness of religious beliefs, stating that cognitive science of religion shows that (...) religious beliefs are natural and natural beliefs ought to be trusted in the absence of counterevidence. This argument received its most influential defense from Justin Barrett in a number of papers, some in collaboration with Kelly James Clark. I will discuss their version of the argument and argue that it fails because the natural beliefs discovered by cognitive scientists of religion are not the religious beliefs of the major world religions. A survey of the evidence from cognitive science of religion will show that cognitive science does show that other beliefs come natural and that these can thus be deemed trustworthy in the absence of counterevidence. These beliefs are teleological beliefs, afterlife beliefs and animistic theistic beliefs. (shrink)

Symposium on Nietzsche's Constructivism (Routledge, 2018), replies to Adler, Cabrera, Doyle, Migotti, Sinhababu, Pedersen.

I argue that God lacks the standing to blame or punish people for their sin if theological determinism is true, and that this is so even if sinners deserve both blame and punishment for sins God determines them to commit (and thus even if theological determinism is compatible with human free will and moral responsibility). I then respond to two recent objections to this conclusion, one by John Ross Churchill, the other by Patrick Todd. I conclude by noting several implications (...) of the position here defended.

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.

In this paper, I take up one of Wang Yangming’s most audacious philosophical claims, which is that an achievement that is entirely concerned with correcting one’s own inner states, called “establishing sincerity” (licheng 立誠) can help one to fully grasp (jin 盡) all ethically pertinent matters, including those that would seem to require some ability to know or track facts about the wider world (e.g., facts about people very different from ourselves, facts about the needs of plants and animals). Wang (...) makes a claim to this effect in some of his letters and recorded discussions. -/- I begin with a brief, historical reconstruction of what Wang means by “establishing sincerity” and then turn to two sets of controversies regarding his audacious claim. The first has to do with how we should understand the proposal that establishing sincerity helps or positions a person to fully grasp all ethically significant concerns. On the interpretation of Chen Lai 陳來, Wang doesn’t think that establishing sincerity is sufficient by itself to have this grasp, only that it lays a necessary psychological foundation for all attempts to do so, so that it leaves much more work to do. I largely agree with Chen’s reading but find it isn’t strong enough to capture what’s most important and controversial about Wang’s view. On my stronger reading, Wang doesn’t just think that establishing sincerity provides a necessary foundation for a complete grasp, he also thinks that it describes the most difficult and demanding step or part of the process – the other steps come much more naturally and easily. The second set of controversies has to do with whether we can preserve Wang’s core account of virtuous moral agency without his strong ethical nativism, according to which we have an inherent capacity and disposition to track what is ethically important or salient about people and things very much unlike ourselves. I consider some arguments and interpretations of Wang’s thought that might allow us to bypass his nativist presuppositions, and conclude that they do not succeed. Even if we cannot accept his ethical nativism, however, there is a range of important ethical norms for which Wang’s prescriptions are powerful and prudent. The result of this study, I hope, will be an account of Wang’s thought which better positions us to see what parts are (and are not) worth bringing to ongoing debates about the nature of ethics, moral knowledge, and moral virtue.

Philosophers who study the problem of biological function often begin their deliberations by reflecting on the functions of parts of animals, or the behavior of animals. Applying theories of biological function to unconventional or borderline cases can help us to better evaluate and refine those theories. This is the case when we consider whether parts of transposable elements —bits of “selfish” DNA that move about within a host genome—have functions of their own, that is, whether the parts of TEs have (...) the function of helping the TE move about within the genome. Here I argue that whether or not the parts of TEs have functions depends crucially on whether collections of TEs form “populations,” by which I mean, here, a group of individuals of the same type that impact one another’s chances of persistence or multiplication, by impacting one another’s access to a shared resource. I think there is suggestive, but not conclusive, evidence that some TEs have functions of their own. Considering the problem of TE functionality, then, has value both for philosophy and for biology.

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.

In this paper, I maintain—contrary to those commentators who regard him as a principled republican—that at the core of Spinoza’s political theory is an instrumental, rather than an intrinsic, defense of democratic procedures. Specifically, Spinoza embraces democratic decision procedures primarily because they tend to result in better decisions, defined relative to a procedure-independent standard of correctness or goodness. In contemporary terms, Spinoza embraces an epistemic defense of democracy. I examine Spinoza’s defense of collective governance, showing not only how it differs (...) from other accounts of his time but also how it might contribute to current debates about the epistemic standing of popular governing bodies. In the opening section I defend the thesis that has been contested in recent years that Spinoza was, in fact, a consistent democrat. The second section focuses on procedural (i.e., intrinsic) defenses of democracy, paying particular attention to the republican version of proceduralism that was prominent in Spinoza’s time. And in the final section I present my case for reading Spinoza as an epistemic democrat, comparing his epistemic defense with contemporary versions. What we find are not only striking anticipations of contemporary arguments, but also largely neglected lines of argumentation that reveal both the potential epistemic advantages and disadvantages of democracy.

In this essay I consider what grounds Spinoza’s defense of the freedom to philosophize, considering why Spinoza doesn’t think that we should attempt to snuff out irrationality and dissolution with the law’s iron fist. In the first section I show that Spinoza eschews skeptical, pluralistic, and rights-based arguments for toleration. I then delineate the prudential, anticlerical roots of Spinoza’s defense, before turning in the final section to consider just how far and when toleration contributes to the guiding norms of governance: (...) peace and empowerment. Once we see how the defense of toleration is anchored in these norms, we form a clearer picture of Spinoza as a liberal perfectionist for whom the bounds of political toleration depends on pragmatic and circumstance-specific assessments of what conduces to the flourishing of the state. This will help to illuminate what is distinctive—and, perhaps, distinctively commendable—about Spinoza’s form of liberalism. (shrink)

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)

Mainstream teleosemantics is the view that mental representation should be understood in terms of biological functions, which, in turn, should be understood in terms of selection processes. One of the traditional criticisms of teleosemantics is the problem of novel contents: how can teleosemantics explain our ability to represent properties that are evolutionarily novel? In response, some have argued that by generalizing the notion of a selection process to include phenomena such as operant conditioning, and the neural selection that underlies it, (...) we can resolve this problem. Here, we do four things: we develop this suggestion in a rigorous way through a simple example, we draw on recent neurobiological research to support its empirical plausibility, we defend the move from a host of objections in the literature, and we sketch how the picture can be extended to help us think about more complex “conceptual” representations and not just perceptual ones.

The problem of plant individuality is something which has vexed botanists throughout the ages, with fashion swinging back and forth from treating plants as communities of individuals (Darwin 1800 ; Braun and Stone 1853 ; Münch 1938 ) to treating them as organisms in their own right, and although the latter view has dominated mainstream thought most recently (Harper 1977 ; Cook 1985 ; Ariew and Lewontin 2004 ), a lively debate conducted mostly in Scandinavian journals proves that the issues (...) are far from being resolved (Tuomi and Vuorisalo 1989b ; Fagerström 1992 ; Pan and Price 2001 ). In this paper I settle the matter once and for all, by showing which elements of each side are correct. (shrink)

This chapter develops the idea that the germ-soma split and the suppression of individual fitness differences within the corporate entity are not always essential steps in the evolution of corporate individuals. It illustrates some consequences for multilevel selection theory. It presents evidence that genetic heterogeneity may not always be a barrier to successful functioning as a higher-level individual. This chapter shows that levels-of-selection theorists are wrong to assume that the central problem in transitions is always that of minimizing within-group competition. (...) Evidence of intralevel conflict does not qualify as evidence against the existence of a higher level of selection. (shrink)

I present and defend the generalized selected effects theory (GSE) of function. According to GSE, the function of a trait consists in the activity that contributed to its bearer’s differential reproduction, or differential retention, within a population. Unlike the traditional selected effects (SE) theory, it does not require that the functional trait helped its bearer reproduce; differential retention is enough. Although the core theory has been presented previously, I go significantly beyond those presentations by providing a new argument for GSE (...) and defending it from a recent objection. I also sketch its implications for teleosemantics and philosophy of medicine. (shrink)

In this journal, Schulte develops a novel solution to the problem of distal content: by virtue of what is a mental representation about a distal object rather than a more proximal cause of that representation? Schulte maintains that in order for a representation to have a distal content, it must be produced by a constancy mechanism, along with two other conditions. I raise three objections to his solution. First, a core component of Schulte's solution is just a restrictive version of (...) Dretske's solution, but Schulte gives no argument for his restriction. Second, his proposed solution to a disjunction problem is ad hoc. Finally, his ‘far-out’ version of the distality problem is not a version of the distality problem at all. I conclude that Dretske's solution is preferable to Schulte's. (shrink)

此研究的目的是論述在悲劇發生時哲學具作為慰藉手段的作用。西方哲學的羅馬希臘化時期，跨越了不同的哲學流派，蓬勃發展了一種被稱為“慰藉”（consolatione）的特殊哲學著作的文體。因此，哲學家和哲學 思想家撰寫了幾部名為“De consolatione”（On Consolation）的哲學著作，一直持續到中世紀，如波埃修斯（Boethius）的通俗著作“De Consolatione Philosophia”（On the Consolation of Philosophy）。在羅馬希臘化時期哲學家現存的著作中，塞內卡的著作可以說是最多且篇幅相當長，是寫給他所認識遭受悲劇的人的。因此，本文試圖在塞內卡的著作中探索這種特殊的哲學體裁—論慰藉。本文要探究 他如何使用這種哲學體裁來幫助遭受悲劇的人，特別是遭受親人的死亡，而獲得心靈的平靜與安寧。其目的是利用塞內卡關於“De Consolatione”的著作來反思世界各地許多遭受Covid-19 疫情帶來悲劇的人。即是證明和探索哲學思考在悲劇時的作用。這表明，哲學或哲學家不是悲劇時的無助旁觀者，而是與人類境遇具有生存相關性的活動。更具體一點，此論文的目的就是回答下面這個問題：哲學可以對超過四百 萬因爲疫情而直接死亡的人（不包括那些間接死亡的人）其遭受苦死的家人和朋友說些什麼？今天哲學家如何為因 Covid-19 疫情而遭受悲劇的人們帶來慰藉？此論文認為，哲學家塞內卡（Seneca）可以教今天的哲學家如何運用哲學作為處理當今悲劇的手段。因此，本文架構如下： 1. 塞內卡哲學的簡要闡述。 2. 論述慰藉之哲學文體。 3. 塞內卡《慰藉》著作的哲學論述。 4. 塞內卡思想對 Covid-19 疫情的反思。 5. 結論。.

When speakers utter conflicting moral sentences, it seems clear that they disagree. It has often been suggested that the fact that the speakers disagree gives us evidence for a claim about the semantics of the sentences they are uttering. Specifically, it has been suggested that the existence of the disagreement gives us reason to infer that there must be an incompatibility between the contents of these sentences. This inference then plays a key role in a now-standard argument against certain theories (...) in moral semantics. In this paper, we introduce new evidence that bears on this debate. We show that there are moral conflict cases in which people are inclined to say both that the two speakers disagree and that it is not the case at least one of them must be saying something incorrect. We then explore how we might understand such disagreements. As a proof of concept, we sketch an account of the concept of disagreement and an independently motivated theory of moral semantics which, together, explain the possibility of such cases. (shrink)

This article presents a distinct sense of ‘mechanism’, which I call the functional sense of mechanism. According to this sense, mechanisms serve functions, and this fact places substantive restrictions on the kinds of system activities ‘for which’ there can be a mechanism. On this view, there are no mechanisms for pathology; pathologies result from disrupting mechanisms for functions. Second, on this sense, natural selection is probably not a mechanism for evolution because it does not serve a function. After distinguishing this (...) sense fromsimilar explications of ‘mechanism’, I argue that it is ubiquitous in biology and has valuable epistemic benefits. (shrink)

I distinguish two forms of pluralism about biological functions, between-discipline pluralism and within-discipline pluralism. Between-discipline pluralism holds that different theories of function are appropriate for different subdisciplines of biology and psychology. I provide reasons for rejecting this view. Instead, I recommend within-discipline pluralism, which emphasizes the plurality of function concepts at play within any given subdiscipline of biology and psychology.

There is a certain metaphor that has enjoyed tremendous longevity in the evolution of ageing literature. According to this metaphor, nature has a certain goal or purpose, the perpetuation of the species, or, alternatively, the reproductive success of the individual. In relation to this goal, the individual organism has a function, job, or task, namely, to breed and, in some species, to raise its brood to maturity. On this picture, those who cannot, or can no longer, reproduce are somehow invisible (...) to, or even dispensable to, the evolutionary process. Here, I argue that the metaphor should be discarded, not on the grounds that it is a metaphor, but on the grounds that this particular metaphor distorts our understanding of the evolution of ageing. One reason the metaphor is problematic is that it frames senescence and death as nature’s verdict on the value of older individuals. Instead, we should explore a different metaphor: the lengthy post-reproductive period in humans and some other animals is not an accident of culture, but designed by nature for the purpose of supporting and guiding younger generations. On this alternate picture, different stages of life have their own evolutionary rationales, their distinctive design features, their special mandates. (shrink)

Fictionalism plays a significant role in philosophy today, with defenses spanning mathematics, morality, ordinary objects, truth, modality, and more.1 Fictionalism in the philosophy of science is also gaining attention, due in particular to the revival of Hans Vaihinger’s work from the early twentieth century and to heightened interest in idealization in scientific practice.2 Vaihinger maintains that there is a ubiquity of fictions in science and, among other things, argues that Nietzsche supports the position. Yet, while contemporary commentators have focused on (...) fictionalism in Nietzsche’s moral philosophy, his view of fictions in science has remained largely unexamined.3 In this article, I begin...

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)

Theories of function are conventionally divided up into historical and ahistorical ones. Proponents of ahistorical theories often cite the ahistoricity of their accounts as a major virtue. Here, I argue that none of the mainstream “ahistorical” accounts are actually ahistorical. All of them embed, implicitly or explicitly, an appeal to history. In Boorse’s goal-contribution account, history is latent in the idea of statistical-typicality. In the propensity theory, history is implicit in the idea of a species’ natural habitat. In the causal (...) role theory, history is required for making sense of dysfunction. I elaborate some consequences for the functions debate. (shrink)

One problem for Molinism that critics of the view have pressed, and which Molinists have so far done little to address, is that even if there are true counterfactuals of freedom, it is puzzling how God could possibly know them. I defuse this worry by sketching a plausible model of the mechanics of middle knowledge which draws on William Alston’s direct acquaintance account of divine knowledge.

A standard problem with the objectivity of social scientific theory in particular is that it is either self-referential, in which case it seems to undermine itself as ideology, or self-excepting, which seem pragmatically self-refuting. Using the example of Marx and his theory of ideology, I show how self-referential theories that include themselves in their scope of explanation can be objective. Ideology may be roughly defined as belief distorted by class interest. I show how Marx thought that natural science was informed (...) by class interest but not therefore necessarily ideology. Capitalists have an interest in understanding the natural world (to a point) so that they can manipulate it for profit. Their survival in the marketplace often depends on their competitive success in doing so. The fact that their interventions into nature, driven by class interest, often succeed, is evidence of the reliability and truth of their natural scientific theories. -/- With social science, capitalists have a partial interest in understanding the world, so that they may maintain their class power, ideological hegemony, and a reasonably stable and self-reproducing economy. Some bourgeois social science, Marx thinks, is therefore vindicated the same way that natural science is, because of, not despite, its success in promoting the class interests that cause it. But the capitalist class, Marx thinks, also has an interest in obfuscating the truth about the social world. It would undermine the stability of capitalism, for example, for the bourgeoisie to adopt what Marx thinks to be the correct social theory, Marxism, and proclaim to the world that capitalism is exploitative and unstable. Capitalism creates a a need for ideological social theories that, driven by class interest, represent capitalism as just, natural, inevitable, and unalterable. If Marxism is correct, while these theories may further capitalist interests, they will not withstand the test of time as capitalist exploitation and instability engenders countersystemic political action. -/- How, then can we know, according to Marx, that Marxism is correct, as applied to itself? In part it is whether it succeeds in further the class interests that cause it. If workers adopt bourgeois theories and Marxism is right, they will find themselves frustrated in pursuit of goals that they have, such as improving their well-being, and if Marxism is wrong, then those theories will help them further their own goals. Similarly with Marxism: if it is right, then workers who adopt it should in the long run have more success in furthering their own goals, and if not, then not. But it is question begging to say that our confidence in the reliability of Marxism is enhanced by its successful promotion of goals that capitalists do not have but (according to Marxism) workers do. To avoid this problem it is necessary to compare the relative success of each sort of theory in promoting the interests and needs that the respective classes have independently of the theory, as well as by the usual criteria of scientific theory choice. -/- Thus the Soviet variant of Marxism was fairly decisively refuted by its failure to generate the support of its own designated constituency necessary to grow and survive. Whether the same is true of other varieties of Marxism or of capitalist social theory, it is, as Zhou En Lai said when asked whether the French Revolution had succeeded, too soon to tell, at least in any definitive way. However, and this is the point of the paper, an objective test of Marxism is possible even though Marxism says that all theory is informed by class interest. The question is whether the interests are in discovering or obfuscating the truth. The point is not limited to Marx, but applies to any self-referential social scientific theory that includes itself in its scope. -/- Keywords: ideology, self-referential theory, self-reference, reliabilism, objectivity, Marx, Marxism, sociology of science, class interest, classes, capitalism, bourgeoisie, workers, working class, social theory of knowledge, confirmation of scientific theory.
