The paper argues against Peacocke's moderate rationalism in modality. In the first part, I show, by identifying an argumentative gap in its epistemology, that Peacocke's account has not met the Integration Challenge. I then argue that we should modify the account's metaphysics of modal concepts in order to avoid implausible consequences with regards to their possession conditions. This modification generates no extra explanatory gap. Yet, once the minimal modification that avoids those implausible consequences is made, the resulting account cannot support (...) Peacocke's moderate rationalism. (shrink)

This paper elaborates and defends an expressivist account of the claims of mind-independence embedded in ordinary moral thought. In response to objections from Zangwill and Jenkins it is argued that the expressivist 'internal reading' of such claims is compatible with their conceptual status and that the only 'external reading' available doesn't commit expressivisists to any sort of subjectivism. In the process a 'commitment-theoretic' account of the semantics of conditionals and negations is defended.

Social metaphysics is a source of important philosophical and moral insight. Furthermore, much social metaphysics appears to be substantive. However, some have recently argued that standard views of metaphysics cannot accommodate substantive social metaphysics. In this paper I offer a new diagnosis of this problem and defend a new solution, showing that this problem is an illuminating lens through which to examine the nature and boundaries of metaphysics. This case instantiates a broad, common pattern generated by attempts to align distinctions (...) between realism and anti-realism, mind-independence and mind-dependence, and legitimate and non-legitimate inquiry. I show that the best response is to abandon the association between substantive metaphysics and mind-independence, and I sketch a new definition of substantivity, given in terms of explanatory power, that makes room for substantive social metaphysics while also offering an attractive basis for general metaphysics.

Samuel Johnson claimed to have refuted Berkeley by kicking a stone. It is generally thought that Johnson misses the point of Berkeley's immaterialism for a rather obvious reason: Berkeley never denied that the stone feels solid, but only that the stone could exist independently of any mind. I argue that Johnson was on the right track. On my interpretation, Johnson’s idea is that because the stone feels to resist our effort, the stone seems to have causal powers. But if appearances (...) are to be taken at face value, as Berkeley insists, then the stone has causal powers. I argue that such causal powers threaten not only Berkeley’s view that only minds are active, but also, and more fundamentally, his central claim that sensible things depend on perception. (shrink)

I defend a novel view of how social kinds (e.g., money, women, permanent residents) depend on our mental states. In particular, I argue that social kinds depend on our mental states in the following sense: it is essential to them that they exist (partially) because certain mental states exist. This analysis is meant to capture the very general way in which all social kinds depend on our mental states. However, my view is that particular social kinds also depend on our (...) mental states in more specific ways—some of them causal, others metaphysical. I defend a minimal but metaphysically important notion of essence—one that takes as primary that the essential properties of a kind constitute its identity—and argue that this minimal notion of essence is all that is needed to vindicate my claim that social kinds are essentially mind-dependent.

Grounding and explanation are said to be intimately connected. Some even maintain that grounding just is a form of explanation. But grounding and explanation also seem importantly different—on the face of it, the former is ‘worldy’ or ‘objective’ while the latter isn’t. In this paper, we develop and respond to an argument to the effect that there is no way to fruitfully address this tension that retains orthodox views about grounding and explanation but doesn’t undermine a central piece of methodology, (...) namely that explanation is a guide to ground.

The perennial nature of some of philosophy’s deepest problems is a puzzle. Here, one problem, the realism–anti-realism debate, and one type of explanation for its longevity, are examined. It is argued that realism and anti-realism form a dialetheic pair: While they are in fact each other’s logical opposite, nevertheless, both are true (and both false). First, several reasons why one might think such a thing are presented. These reasons are merely the beginning, however. In the following sections, the dialetheic conclusion (...) is directly argued for by showing how realism and anti-realism satisfy Priest’s “inclosure schema”. In the last section and the conclusion, the conscious mind’s role in creating realism and anti-realism is discussed. This role further supports the conclusion that realism and anti-realism form a dialetheic pair. (shrink)

This paper concerns an epistemological objection against mathematical platonism, due to Hartry Field.The argument poses an explanatory challenge – the challenge to explain the reliability of our mathematical beliefs – which the platonist, it’s argued, cannot meet. Is the objection compelling? Philosophers disagree, but they also disagree on (and are sometimes very unclear about) how the objection should be understood. Here I distinguish some options, and highlight some gaps that need to be filled in on the potentially most compelling version (...) of the argument. (shrink)

This book is in honour of Professor Anna-Sofia Maurin on her 50th birthday. It consists of eighteen essays on metaphysical issues written by Swedish and international scholars.

Together, these entail that for every true proposition p, there exists some thing which could not exist and p be false.

It is a truism that humans are social animals. Thus, it is no surprise that we understand the world, each other, and ourselves in terms of social kinds such as money and marriage, war and women, capitalists and cartels, races, recessions, and refugees. Social kinds condition our expectations, inform our preferences, and guide our behavior. Despite the prevalence and importance of social kinds, philosophy has historically devoted relatively little attention to them. With few exceptions, philosophers have given pride of place (...) to the kinds studied by the natural sciences, especially physics. However, philosophical interest in social kinds is growing in recent years. I critically examine answers to a cluster of related questions concerning the metaphysics of social kinds. Are social kinds natural kinds? Do social kinds have essences? Are social kinds mind dependent? Are social kinds real? (shrink)

State of the art paper on the topic realism/anti-realism. The first part of the paper elucidates the notions of existence and independence of the metaphysical characterization of the realism/anti-realism dispute. The second part of the paper presents a critical taxonomy of the most important positions and doctrines in the contemporary literature on the domains of science and mathematics: scientific realism, scientific anti-realism, constructive empiricism, structural realism, mathematical Platonism, mathematical indispensability, mathematical empiricism, intuitionism, mathematical fictionalism and second philosophy.

It is often claimed that there is an explanatory divide between an expressivist account of normative discourse and a realist conception of normativity: more precisely, that expressivism and realism offer conflicting explanations of (i) the metaphysical structure of the normative realm, (ii) the connection between normative judgment and motivation, (iii) our normative beliefs and any convergence thereof, or (iv) the content of normative thoughts and claims. In this paper I argue that there need be no such explanatory conflict. Given a (...) minimalist approach to the relevant metaphysical and semantic notions, expressivism is compatible with any explanation that would be acceptable as a general criterion for realism.

This paper outlines a new metasemantic theory of moral reason statements, focused on explaining how the reasons thus stated can be inescapable. The motivation for the theory is in part that it can explain this and other phenomena concerning moral reasons. The account also suggests a general recipe for explanations of conceptual features of moral reason statements. (Published with Open Access.).

Despite the efforts of meta-ethical expressivists to rebut such worries, one objection raised over and over again against expressivism is that, if the theory is true, matters of morality must be mind-dependent in some objectionable way. This paper develops an argument which not only shows that this is and cannot be the case, but also – and perhaps more importantly – offers a diagnosis why philosophers are nevertheless so often led to think otherwise.

A central feature of ordinary moral thought is that moral judgment is mind-independent in the following sense: judging something to be morally wrong does not thereby make it morally wrong. To deny this would be to accept a form of subjectivism. Neil Sinclair (2008) makes a novel attempt to show how expressivism is simultaneously committed to (1) an understanding of moral judgments as expressions of attitudes and (2) the rejection of subjectivism. In this paper, I discuss Sinclair’s defense of anti-subjectivist (...) moral mind-independence on behalf of the expressivist, and I argue that the account does not fully succeed. An examination of why it does not is instructive, and it reveals a fundamental dilemma for the expressivist. I offer a suggestion for how the expressivist might respond to the dilemma and so uphold Sinclair’s defense. (shrink)

This paper presents a challenge to the coherence of social constructivism about science. It introduces an objection according to which social constructivism appeals to the authority of science regarding the nature of reality and so cannot coherently deny that authority. The challenge is how to avoid this incoherence.

I address an intuition commonly endorsed by metaphysicians, that there must be a fundamental layer of reality, i.e., that chains of ontological dependence must terminate: there cannot be turtles all the way down. I discuss applications of this intuition with reference to Bradley’s regress, composition, realism about the mental and the cosmological argument. I discuss some arguments for the intui- tion, but argue that they are unconvincing. I conclude by making some suggestions for how the intuition should be argued for, (...) and discussing the ramifications of giving the justification I think best. (shrink)

Quasi-realists have proposed an “internal” reading of the mind-independence claim embedded in our moral discourse, according to which the claim to mind-independence itself is a moral claim. I argue against such a quasi-realist “internal” reading. My objection is that quasi-realists cannot plausibly explain why the majority of us, either implicitly or explicitly, take moral mind-independence to be a metaethical notion. Quasi-realists either must attribute a quite obvious mistake to most metaethical theorists without explaining why they cannot recognize it, or give (...) us an intolerably ad hoc explanation about why ordinary moral speakers fail to understand their own words. Without properly addressing this problem, we have good reason to reject the quasi-realist account of moral mind-independence. (shrink)

This paper investigates the nature of scientific realism. I begin by considering the anomalous fact that Bas van Fraassen’s account of scientific realism is strikingly similar to Arthur Fine’s account of scientific non-realism. To resolve this puzzle, I demonstrate how the two theorists understand the nature of truth and its connection to ontology, and how that informs their conception of the realism debate. I then argue that the debate is much better captured by the theory of truthmaking, and not by (...) any particular theory of truth. To be a scientific realist is to adopt a realism-relevant account of what makes true the scientific theories one accepts. The truthmaking approach restores realism’s metaphysical core—distancing itself from linguistic conceptions of the debate—and thereby offers a better characterization of what is at stake in the question of scientific realism.

Quasi-realists aim to account for many of the trappings of metanormative realism within an expressivist framework. Chief among these is the realist way of responding to the Euthyphro dilemma: quasi-realists want to join realists in being able to say, "It’s not the case that kicking dogs is wrong because we disapprove of it. Rather, we disapprove of kicking dogs because it’s wrong." However, the standard quasi-realist way of explaining what we are up to when we assert the first of these (...) two sentences rests on a mistaken identification of metaphysical dependence (or grounding) with counterfactual covariation. This chapter proposes a better way for expressivists to understand such sentences, on which they serve to express complex states of mind in which an attitude bears a relation of psychological dependence (or basing) to another state of mind. It is argued that this proposal is a natural, versatile, and fruitful approach for expressivists to take that helps them secure the first half of the Euthyphro contrast—but at the cost of making it difficult to see how expressivists can make sense of that contrast’s second half.

I shall defend the view that the experience of resistance gives us a direct phenomenal access to the mind-independence of perceptual objects. In the first part, I address an objection against the very possibility of experiencing mind-independence. The possibility of an experience of mind-independence being secured, I argue in the second part that the experience of resistance is the kind of experience by which we access mind-independence.

This paper formulates a general epistemological argument against what I call non-causal realism, generalizing domain specific arguments by Benacerraf, Field, and others. First I lay out the background to the argument, making a number of distinctions that are sometimes missed in discussions of epistemological arguments against realism. Then I define the target of the argument—non-causal realism—and argue that any non-causal realist theory, no matter the subject matter, cannot be given a reasonable epistemology and so should be rejected. Finally I discuss (...) and respond to several possible responses to the argument. In addition to clearing up and avoiding numerous misunderstandings of arguments of this kind that are quite common in the literature, this paper aims to present and endorse a rigorous and fully general epistemological argument against realism.

I distinguish Local Constructivism (humans play a constitutive role in constructing some of the objects we have epistemic access to) from Global Constructivism (humans play a constitutive role in constructing all of the objects we have epistemic access to). I explicate and clarify Local Constructivism and show how the metaphysical concerns which motivate endorsing Local Constructivism about some objects (e.g. social objects, modal objects) differ from the epistemic and semantic concerns which motive endorsing Global Constructivism. I, then, examine the criticisms (...) Realists typically present against Constructivism. I argue that, although these criticisms undermine Global Constructivism, Local Constructivism is immune to them. If one has anti-Realist inclinations, but wishes to avoid the morass anti-Realism usually falls into (aka: anti-Realist Boogeyman), one should endorse Local, rather than Global, Constructivism.

Realism and anti-realism about a domain of thought are metaphysical theses that involve the natures of the truthmakers in that domain and the truthmaking relation that is operant in the domain. Truthmaker theory is not exclusive territory for realists: anti-realist views are also best understood in terms of how they understand truthmakers and truthmaking. In particular, I explore the possibility of projectivist truthmaking, and show how it makes sense of quasi-realism. In addition to critically examining some extant accounts of the (...) relationship between realism and truthmaking, I offer an account that best captures the nature of the various realism debates.

In everyday speech we seem to refer to such things as abstract objects, moral properties, or propositional attitudes that have been the target of metaphysical and/or epistemological objections. Many philosophers, while endorsing scepticism about some of these entities, have not wished to charge ordinary speakers with fundamental error, or recommend that the discourse be revised or eliminated. To this end a number of non-revisionary antirealist strategies have been employed, including expressivism, reductionism and hermeneutic fictionalism. But each of these theories faces (...) forceful objections. In particular, we argue, proponents of these strategies face a dilemma: either concedes that their theory is revisionary, or adopt an implausible account of speaker-meaning whereby the content of certain types of utterance is opaque to their speakers. In this paper we introduce a new type of antirealist strategy, which is thoroughly non-revisionary, and leaves speaker-meaning transparent to speakers. We draw on work on pragmatics in the philosophy of language to develop a theory we call ‘pragmatic antirealism’. The pragmatic antirealist holds that while the sentences of the discourses in question have metaphysically contentious truth conditions, ordinary utterances of them are pragmatically modified in context in such a way that speakers do not incur commitment to those truth conditions. After setting out the theory, we show how it might be developed for both mathematical and ethical discourse, before responding to some likely objections. (shrink)

When it comes to the metaethical task of explaining and making sense of what it is that we are doing while doing ethics, the subject of moral objectivity occupies an important and special place within that task. Thus, it is often agreed that being able to explain and justify the objective features of common moral practice is one of if not the most important task for any metaethical theory to undertake. In this dissertation, I tackle the issue of ethical objectivity (...) on behalf of metaethical constructivism. To be more precise, my aim is to make plausible, strengthen, and defend the constructivist original contribution to contemporary metaethics by developing a novel constructivist account on the objectivity of ethics. While the account that I develop herein presents a novel and independent approach to the subject of moral objectivity on behalf of constructivism, it also places itself between the two other positions within the constructivist camp that openly strive to secure ethical objectivity – namely Kantianism on the one hand, and the more recently developed Humean objectivist view on the other. It is for the latter reason that I call my own view the hybrid view. (shrink)

This paper introduces a modal epistemology that centers on inference to the best explanation (i.e. abduction). In introducing this abduction-centered modal epistemology, the paper has two main goals. First, it seeks to provide reasons for pursuing an abduction-centered modal epistemology by showing that this epistemology aids a popular stance on the mind-body problem and allows an appealing approach to modality. Second, the paper seeks to show that an abduction-centered modal epistemology can work by showing that abduction can establish claims about (...) necessity/possibility (i.e. modal claims)—where ‘necessity’ and ‘possibility’ denote metaphysical necessity and possibility, ways things may or may not have been given how they actually are.

The goal of the research programme I describe in this article is a realist epistemology for arithmetic which respects arithmetic's special epistemic status (the status usually described as a prioricity) yet accommodates naturalistic concerns by remaining fundamentally empiricist. I argue that the central claims which would allow us to develop such an epistemology are (i) that arithmetical truths are known through an examination of our arithmetical concepts; (ii) that (at least our basic) arithmetical concepts are accurate mental representations of elements (...) of the arithmetical structure of the independent world; (iii) that (ii) obtains in virtue of the normal functioning of our sensory apparatus. The first of these claims protects arithmetic's special epistemic status relative, for example, to the laws of physics, the second preserves the independence of arithmetical truth, and the third ensures that we remain empiricists.

Metaethical constructivists have proposed many arguments against mind-independence moral realism. In this paper I resume the constructivist critique against realism on the grounds of considerations stemming from moral phenomenology. My claim is that constructivism, in contrast to moral mind-independence theories such as moral realism or quasi-realism, fares better in accounting for the phenomenology of moral practice and discourse. Given the importance of phenomenological investigation for metaethical theorizing as such, my argument shows that there is good reason to prefer constructivism over (...) any kind of theory that endorses the mind-independence of morality.
