Debunking arguments—also known as etiological arguments, genealogical arguments, access problems, isolation objec- tions, and reliability challenges—arise in philosophical debates about a diverse range of topics, including causation, chance, color, consciousness, epistemic reasons, free will, grounding, laws of nature, logic, mathematics, modality, morality, natural kinds, ordinary objects, religion, and time. What unifies the arguments is the transition from a premise about what does or doesn't explain why we have certain mental states to a negative assessment of their epistemic status. I examine (...) the common, underlying structure of the arguments and the different strategies for motivating and resisting the premises of debunking arguments. (shrink)

A basic way of evaluating metaphysical theories is to ask whether they give satisfying answers to the questions they set out to resolve. I propose an account of “third-order” virtue that tells us what it takes for certain kinds of metaphysical theories to do so. We should think of these theories as recipes. I identify three good-making features of recipes and show that they translate to third-order theoretical virtues. I apply the view to two theories—mereological universalism and plenitudinous platonism—and draw (...) out their third-order virtues and vices. One lesson is that there is an important difference between essentially and non-essentially third-order vicious theories. I also argue that if a theory is essentially third-order vicious, it cannot be assessed for more standard “second-order” theoretical virtues and vices, like parsimony. This motivates the idea that third-order virtues are distinct from second-order ones. Finally, I suggest that the relationship between truth, progress, and third-order virtue is more complex than it seems. (shrink)

A range of current truth-value realist philosophies of mathematics allow one to reduce the Benacerraf Problem to a problem concerning mathematicians' ability to recognize which conceptions of pure mathematical structures are coherent – in a sense which can be cashed out in terms of logical possibility. In this paper I will clarify what it takes to solve this `residual' access problem and then present a framework for solving it.

In this paper, I develop a metasemantics for relaxed moral realism. More precisely, I argue that relaxed realists should be inferentialists about meaning and explain that the role of evaluative moral vocabulary is to organise and structure language exit transitions, much as the role of theoretical vocabulary is to organise and structure language entry transitions.

Several philosophers have recently argued that evolutionary considerations undermine the justification of all objectivist moral beliefs by implying a hypothetical disagreement: had our evolutionary history been different, our moral beliefs would conflict with the moral beliefs of our counterfactual selves. This paper aims at showing that evolutionary considerations do not imply epistemically relevant moral disagreement. In nearby scenarios, evolutionary considerations imply tremendous moral agreement. In remote scenarios, evolutionary considerations do not entail relevant disagreement with our epistemic peers, neither on a (...) narrow nor on a broad conception of peerhood. In conclusion, evolutionary considerations do not reveal epistemically troubling kinds of disagreement. Anti-objectivists need to look elsewhere to fuel their sceptical argument. (shrink)

In response to comments on my book, Being Realistic about Reasons, by Justin Clarke-Doane, David Enoch and Tristram McPherson, and Gideon Rosen, I try to clarify my domain-based view of ontology, my understanding of the epistemology of normative judgments, and my interpretation of the phenomenon of supervenience.

Street formulated a Darwinian Dilemma for realist theories of value. Much criticism of her formulation of the dilemma targets the second horn, posed by the scientifically implausible assumption of a tracking relation between our attitudes and evaluative truth. This paper shows how a recent wave of metaethical realism, most prominently defended by Scanlon, succeeds without a tracking relation and thus avoids the Darwinian Dilemma in Street's formulation. However, Scanlon's approach, which builds on the concept of a reason relation and defends (...) a metaphysically pluralist, domain‐specific conception of truth, runs into another version of the Darwinian Dilemma. The problem is not that Scanlon's realism assumes a tracking relation but that it assumes what I call reason monolithism – the idea that there is one possible expression of the faculty of reason and that this cognitive faculty could not be otherwise, which is scientifically implausible on similar grounds.

This article enriches discussions about the metaphysics of normative facts with conceptual resources from social ontology that metaethics has neglected so far: the resources of Haslanger’s critical realism as social constructionism. By pointing out the viability of understanding reasons as socially constructed facts, the article shows how normative facts can be understood as features of mind-independent reality that are, however, not features of the universe independently of social practices. The move into social ontology allows us to understand normative facts as (...) mind-independent in a more substantial sense than deflationists do, by stressing individual mind-independence, while denying collective mind-independence – the subsistence independently of established human cultures. The new position can fruitfully mediate between realism, error theory and constructivism. Finally, the metaphysical nuances provided by social ontology pave the way for novel approaches to normative change and progress – thereby indicating pathways to normative theorising that many traditional metaethical positions lack.

Moral disagreement is sometimes thought to pose problems for moral realism because it shows that we cannot achieve knowledge of the moral facts the realists posit. In particular, it is "fundamental" moral disagreement—that is, disagreement that is not due to distorting factors such as ignorance of relevant nonmoral facts, bad reasoning skills, or the like—that is supposed to generate skeptical implications. In this paper, we show that this version of the disagreement challenge is flawed as it stands. The reason is (...) that the epistemic assumptions it requires are incompatible with the possibility of fundamental disagreement. However, we also present an alternative reconstruction of the challenge that avoids the problem. The challenge we present crucially invokes the principle that knowledge requires "adherence". While that requirement is usually not discussed in this context, we argue that it provides a promising explanation of why disagreement sometimes leads to skepticism. (shrink)

If you put chimpanzees from different communities together you can expect mayhem - they are not keen on treating each other nicely. There is closely related species of apes, however, whose members have countless encounters with unrelated specimen on a daily basis and yet almost all get through the day in one piece - that species is us, homo sapiens. But what makes us get along, most of the time? Morality as such is, perhaps surprisingly, not a mainstream research topic (...) in social psychology. Most textbooks in the field do not even mention the term morality at all (and focus on 'prosociality' instead). This relative lack of 'coverage' might have to do with the difficulty of operationalising 'morality' in a fitting way (more on this below). However, morality certainly is a social phenomenon and therefore the collection of Fargas, Jussim, and Van Lange is certainly a step in the right direction; it offers an extensive overview of the field and is suggestive of the vast potential of studying morality through the lens of social psychology.

We argue that Reasons Fundamentalism, as defended by T.M. Scanlon, faces two important difficulties—one ontological, the other epistemological—namely theontological proliferation problemand thereliability challenge.We suggest that formal constructivism can avoid these difficulties, and that Scanlon would do well to adopt it. We also show that Scanlon’s three main objections to this view depend either on a misunderstanding of what formal constructivism is or on a question-begging argument in favour of realism.
