According to content-relativist theories of moral language, different speakers use the same moral sentences to say different things. Content-relativism faces a well-known problem of lost disagreement. Recently, numerous content-relativists (including the author) have proposed to solve this problem by appeal to various kinds of non-content-based, or broadly pragmatic, disagreement. This presents content-relativists with a new problem—of found agreement. Which (if any) of these newly identified kinds of conflict is correctly identified as the lost moral disagreement we were looking for? This (...) paper offers a critical comparison of different content-relativist proposals. It divides them into two broad categories, quasi-expressivist theories (QED) and metalinguistic theories (MLD). Objections to each are considered, and QED is tentatively found to be superior.

If there is such a thing as objectively existing prescriptivity, as the moral realist claims, then we can also explain why—and we need not deny that—strong internalism is true. Strong conceptual internalism is true, not because of any belief in any magnetic force thought to be inherent in moral properties themselves, as Mackie argued, but because we do not allow that anyone has ‘accepted’ a normative claim, unless she is prepared to some extent to act on it.

According to the error theory, normative judgements are beliefs that ascribe normative properties, even though such properties do not exist. In this paper, I argue that we cannot believe the error theory, and that this means that there is no reason for us to believe this theory. It may be thought that this is a problem for the error theory, but I argue that it is not. Instead, I argue, our inability to believe the error theory undermines many objections that (...) have been made to this theory. (shrink)

The attempt to vindicate the objectivity of morality tops the list of philosophical obsessions. In this paper I consider the rationality of searching for such a vindication. I argue that the only justification of our efforts lies in our belief in moral objectivity; that this belief can be as well, if not better, explained by wishful thinking and other cognitive biases; that as a research community we have failed to take precautions against such biases; and that as a result we (...) have been making disproportionate, and therefore irrational, efforts to establish moral objectivity.

While the meta‐ethical error theory has been of philosophical interest for some time now, only recently a debate has emerged about the question what is to be done if the error theory turns out to be true. This paper argues for a novel answer to this question, namely revolutionary expressivism: if the error theory is true, we should become expressivists. Additionally, the paper explores certain important but largely ignored methodological issues that arise for reforming definitions generally and with a vengeance (...) in the context of a radical error theory about all practical normative judgements, and suggests how these issues can be resolved.

This paper is about how moral disagreement matters for metaethics. It has four parts. In the first part I argue that moral facts are subject to a certain epistemic accessibility requirement. Namely, moral facts must be accessible to some possible agent. In the second part I show that because this accessibility requirement on moral facts holds, there is a route from facts about the moral disagreements of agents in idealized conditions to conclusions about what moral facts there are. In the (...) third part I build on this route to show that (*) if there is significant moral disagreement in idealized conditions, then our understanding of morality is fatally flawed and we should accept relativism over non-naturalism and quasi-realism. So, if, like many, you think that there would be significant moral disagreement in idealized conditions, you should hold that our understanding of morality is fatally flawed and reject non-naturalism and quasi-realism. In the fourth part of this paper I show that (*) undermines the plausibility of non-naturalism, quasi-realism, and the view that our understanding of morality is not fatally flawed even if we do not have sufficient reason to believe that there would be significant moral disagreement in idealized conditions.

Christopher Cowie has recently argued that companions in guilt arguments against the moral error theory that appeal to epistemic reasons cannot work. I show that such companions in guilt arguments can work if, as we have good reason to believe, moral reasons and epistemic reasons are instances of fundamentally the same relation.

A review of John Skorupski's The Domain of Reasons.

The most basic argument for moral relativism is that different people are (fundamentally) disposed to apply moral terms, such as ‘morally right’ and ‘morally wrong’, and the corresponding concepts, to different (types of) acts. In this paper, I argue that the standard forms of moral relativism fail to account for certain instances of fundamental variation, namely, variation in metaethical intuitions, and I develop a form of relativism—pluralism—that does account for them. I identify two challenges that pluralism faces. To answer the (...) challenges, I first argue that, due to fundamental conceptual variations in ordinary descriptive (nonmoral) discourse, a form of pluralism holds there as well and that this pluralism can answer the corresponding challenges. I then argue that the answers transfer to moral discourse, since the phenomenon of moral variation is structurally identical to that of descriptive variation. (shrink)

Moral error theorists often respond to the epistemic companions in guilt strategy by adopting the Disparity Response: reject the putative parity between moral and epistemic reasons and claim that though the former are irreducibly normative, the latter aren’t. I argue such a response fails. Expanding on Das’ Australas J Philos 95:58–69, work I present a master argument against Disparity Responses: the arguments moral error theorists use to advance their conceptual claim apply in the epistemic domain also. This prohibits the error (...) theorist from adopting epistemic reductionism. I use Jonas Olson’s work as exemplary of moral error theory. I demonstrate that Olson’s argument that the rhetorical authority of moral claims is best explained by the error theorist’s conceptual claim applies equally in the epistemic case. Olson attempts to avoid this by claiming that epistemic claims are reducible to claims about whether our doxastic attitudes live up to their functions. There are two problems with Olson’s argument. Firstly, functional reasons are a species of a common genus – standards reasons – and since Olson’s authority argument against moral reductionism applies to standards reasons, it applies to functional reasons. Secondly, Olson’s claim that we cannot also cast moral reasons as functional is under-supported. I suggest that there is plausible evidence that we can and undermine his arguments against this claim. I do not argue that the epistemic companions in guilt strategy demonstrates the falsity of moral error theory. Rather, I argue that the Disparity Response to the epistemic companions in guilt strategy fails. (shrink)

Evolutionary debunking arguments claim that evolution has influenced our moral faculties in such a way that, if moral realism is true, then we have no positive moral knowledge. I present several popular objections to the standard version of this argument, then give a new EDA that has clear advantages in responding to these objections. Whereas the Standard EDA argues that evolution has selected for many moral beliefs with certain contents, this New EDA claims that evolution has selected for one belief: (...) belief in the claim that categorical reasons exist. If moral realism is true, then this claim is entailed by all positive moral claims, and belief in it is defeated due to evolutionary influence. This entails that if realism is true, then we have no positive moral knowledge. While there may be objections against this New EDA, it is much stronger than the Standard EDA, and one realists ought to worry about. (shrink)

Those whose Way is not the same cannot take counsel together.Confucius, Analects XV, 40Quasi-Realism and Fundamental Disagreement: Egan’s ProblemI believe that it is wrong to open your boiled egg at the big end.

But perhaps that is not the case. Even (...) if we both came to be fully informed about all relevant facts, our disagreement might persist. Perhaps other rational means are available to resolve our disagreement. Perhaps if I became more sensitive, more imaginative, more considerate of others’ needs, I would change my mind.

Perhaps your contrary view would not prove robust in circumstances where you had to endu. (shrink)

I argue against the claim that we should adopt a moral error theory. The intelligibility of our moral practice need offer no questionable metaphysical hostages to fortune. The two most credible policy recommendations that might follow from moral error theory, abolitionism and prescriptive fictionalism, are not very credible.

Evolutionary debunkers claim that evolutionary explanations of moral phenomena lead to sceptical conclusions. The aim of this paper is to show that even if we grant debunkers the speculative claims that evolution provides the best explanation of moral phenomena and that there are no other moral phenomena for which moral facts/properties are indispensable, the sceptical conclusions debunkers seek to establish still do not follow. The problem for debunkers is to link the empirical explanatory claim to the normative conclusion that moral (...) beliefs are unjustified. The paper argues that debunkers face a dilemma, and that neither of the two options available to them supports the sceptical conclusions for which they aim. Consequently, it is claimed, the dialectical force of evolutionary debunking arguments is, at best, exceedingly weak. (shrink)

I argue that, at least on the assumption that if there are epistemic facts they are irreducible, the evolutionary debunking maneuver is prima facie self-debunking because it seems to debunk a certain class of facts, namely, epistemic facts that prima facie it needs to rely on in order to launch its debunking arguments. I then appeal to two recent reconstructions of the evolutionary debunking maneuver (Kahane (2011), Griffiths and Wilkins (2015)) and find them wanting. Along the way I set aside (...) two ways (one envisaged, the other by Sterpetti (2015)) to avoid the self-debunking problem that I find unpromising. I conclude that the evolutionary debunking maneuver needs to clarify the meta-epistemological commitments upon which it is supposed to operate. (shrink)

According to moral error theory, moral discourse is error-ridden. Establishing error theory requires establishing two claims. These are that moral discourse carries a non-negotiable commitment to there being a moral reality and that there is no such reality. This paper concerns the first and so-called non-negotiable commitment claim. It starts by identifying the two existing argumentative strategies for settling that claim. The standard strategy is to argue for a relation of conceptual entailment between the moral statements that comprise moral discourse (...) and the statement that there is a moral reality. The non-standard strategy is to argue for a presupposition relation instead. Error theorists have so far failed to consider a third strategy, which uses a general entailment relation that doesn’t require intricate relations between concepts. The paper argues that both entailment claims struggle to meet a new explanatory challenge and that since the presupposition option doesn’t we have prima facie reason to prefer it over the entailment options. The paper then argues that suitably amending the entailment claims enables them to meet this challenge. With all three options back on the table the paper closes by arguing that error theorists should consider developing the currently unrecognised, non-conceptual entailment claim. (shrink)

In his paper ?The Error in the Error Theory?[this journal, 2008], Stephen Finlay attempts to show that the moral error theorist has not only failed to prove his case, but that the error theory is in fact false. This paper rebuts Finlay's arguments, criticizes his positive theory, and clarifies the error-theoretic position.

Moral abolitionists recommend that we get rid of moral discourse and moral judgement. At first glance this seems repugnant, but abolitionists think that we have overestimated the practical value of our moral framework and that eliminating it would be in our interests. I argue that abolitionism has a surprising amount going for it. Traditionally, abolitionism has been treated as an option available to moral error theorists. Error theorists say that moral discourse and judgement are committed to the existence of moral (...) properties, and that no such properties exist. After error theory is established, abolitionism is one potential way to proceed. However, many error theorists suggest that we retain moral discourse as a sort of fiction. I evaluate some attractions of both fictionalism and abolitionism, arguing that abolitionism is a plausible position. No one doubts that error theorists can be abolitionists. However, what has gone largely undiscussed is that it is open to others to be abolitionists as well. I argue that moral realists of a metaphysically robust sort can and perhaps should be abolitionists. ‘Realist abolitionism’ makes for a surprisingly neat theoretical package, and I conclude that it represents an interesting new option in the theoretical landscape.

Moral obligation and permissibility are usually thought to be interdefinable. Following the pattern of the duality definitions of necessity and possibility, we have that something’s being permissible could be defined as its not being obligatory to not do it. And that something’s being obligatory could be defined as its not being permissible to not do it. In this paper, I argue that neither direction of this alleged interdefinability works. Roughly, the problem is that a claim that some act is obligatory (...) or permissible entails that there is a moral law, whereas a negative claim that some act is not obligatory or not permissible does not. Nevertheless, one direction of the interdefinability can potentially be salvaged. I argue that, if we do not require the conceptual possibility of moral dilemmas, then there is a way to plausibly define obligation in terms of permissibility. I conclude that permissibility is the only feasible deontic primitive. (shrink)

This opinionated survey article discusses a relativist view in metaethics that we can call Appraiser-standard Relativism. According to this view, the truth value of moral judgments varies depending on the moral standard of the appraiser – that is, someone who makes or assesses the judgments. On this view, when two persons judge that, say, lying is always morally wrong; one of the judgments might be true and the other false. The paper presents various forms of this view, contrasts it against (...) other forms of moral relativism, and shortly describes the main arguments for it. It considers the two most pressing objections – from disagreement and from counterintuitivity – and discusses how different forms of Appraiser-standard Relativism are affected by, or can be seen as responses to, these objections. Lastly, it discusses whether Appraiser-standard Relativism rules out moral realism, the view that there are objective moral truths. (shrink)

In his response to my paper ?The Error in the Error Theory? criticizing his and J. L. Mackie's moral error theory, Richard Joyce finds my treatment of his position inaccurate and my interpretation of morality implausible. In this reply I clarify my objection, showing that it retains its force against their error theory, and I clarify my interpretation of morality, showing that Joyce's objections miss their mark.

Moral contextualism is the view that claims like ‘A ought to X’ are implicitly relative to some (contextually variable) standard. This leads to a problem: what are fundamental moral claims like ‘You ought to maximize happiness’ relative to? If this claim is relative to a utilitarian standard, then its truth conditions are trivial: ‘Relative to utilitarianism, you ought to maximize happiness’. But it certainly doesn’t seem trivial that you ought to maximize happiness (utilitarianism is a highly controversial position). Some people (...) believe this problem is a reason to prefer a realist or error theoretic semantics of morals. I argue two things: first, that plausible versions of all these theories are afflicted by the problem equally, and second, that any solution available to the realist and error theorist is also available to the contextualist. So the problem of triviality does not favour noncontextualist views of moral language. (shrink)

Jonas Olson defends a moral error theory in (2014). I will first argue that Olson is not justified in believing the error theory as opposed to moral nonnaturalism in his own opinion. I will then argue that Olson is not justified in believing the error theory as opposed to moral contextualism either (although the latter is not a matter of his own opinion).

According to epistemic instrumentalism, epistemic normativity arises from and depends on facts about our ends. On that view, a consideration C is an epistemic reason for a subject S to Φ only if Φ-ing would promote an end that S has. However, according to the Too Few Epistemic Reasons objection, this cannot be correct since there are cases in which, intuitively, C is an epistemic reason for S to Φ even though Φ-ing would not promote any of S’s ends. After (...) clarifying both EI and the Too Few Epistemic Reasons objection, I examine three major instrumentalist replies and argue that none of them is satisfactory. I end by briefly sketching a fourth possible response, which is, I suggest, more promising than the other three. (shrink)

I first argue that there are many true claims of the form: Φ-ing would be morally required, if anything is. I then explain why the following conditional-type is true: If φ-ing would be morally required, if anything is, then anything is actually morally required. These results allow us to construct valid proofs for the existence of some substantive moral facts—proofs that some particular acts really are morally required. Most importantly, none of my argumentation presupposes any substantive moral claim; I use (...) only plausible claims that most moral skeptics and error theorists can and do accept. The final section diagnoses why my arguments work. Here, I offer an explanation for the supervenience of the moral on the non-moral that may help those worried that the strategy is a sophisticated trick. I conclude by considering two objections. In replying to these objections, I explain why the strategy may allow us to demonstrate more than “obvious” moral truths, and why it may also address a stronger version of error theory, according to which, moral truths are not possible.

Expressivism is a blossoming meta-semantic framework sometimes relying on what Carter and Chrisman call “the core expressivist maneuver.” That is, instead of asking about the nature of a certain kind of value, we should be asking about the nature of the value judgment in question. According to expressivists, this question substitution opens theoretical space for the elegant, economical, and explanatorily powerful expressivist treatment of the relevant domain. I argue, however, that experimental work in cognitive psychology can shed light on how (...) the core expressivist maneuver operates at the cognitive level and that this: raises worries about the aptness of the expressivist question substitution and supports an evolutionary debunking argument against expressivism. Since evolutionary debunking arguments are usually run in favor of expressivism, this creates an obvious puzzle for expressivists. I wrap up by briefly responding to the objection that the debunking argument against expressivism overgeneralizes and, therefore, should be rejected. (shrink)

Despite much discussion over the existence of moral facts, metaethicists have largely ignored the related question of their possibility. This paper addresses the issue from the moral error theorist’s perspective, and shows how the arguments that error theorists have produced against the existence of moral facts at this world, if sound, also show that moral facts are impossible, at least at worlds non-morally identical to our own and, on some versions of the error theory, at any world. So error theorists’ (...) arguments warrant a stronger conclusion than has previously been noticed. This may appear to make them vulnerable to counterarguments that take the possibility of moral facts as a premise. However, I show that any such arguments would be question-begging. (shrink)

The error theory is a metaethical theory that maintains that normative judgments are beliefs that ascribe normative properties, and that these properties do not exist. In a recent paper, Bart Streumer argues that it is impossible to fully believe the error theory. Surprisingly, he claims that this is not a problem for the error theorist: even if we can’t fully believe the error theory, the good news is that we can still come close to believing the error theory. In this (...) paper I show that Streumer’s arguments fail. First, I lay out Streumer’s argument for why we can’t believe the error theory. Then, I argue against the unbelievability of the error theory. Finally, I show that Streumer’s positive proposal that we can come close to believing the error theory is actually undermined by his own argument for why we can’t believe the error theory. (shrink)

Promotion is the relation between an act and a desire that obtains when the act advances or serves the desire. Under what conditions does an act promote a desire? Probabilistic accounts of promotion, the most prominent accounts, analyze promotion in terms of an increase in the probability of the desire’s satisfaction. In this paper, we clarify the promotion relation and explain why probabilistic accounts are attractive. Then we identify two questions probabilistic accounts must answer: the Baseline Question and the Interpretation (...) Question. We discuss and reject the three answers to the Baseline Question found in the literature, and explain the challenge future attempts at answering this question will face. Proponents of probabilistic accounts have not adequately addressed the Interpretation Question. We survey three answers to this question, finding each unsatisfactory. We conclude that no satisfactory probabilistic account has yet been offered, and that there are significant hurdles to providing one in the future. (shrink)

One version of moral error theory maintains that the central problem with morality is an ontological commitment to irreducible normativity. This paper argues that this version of error theory ultimately depends on an appeal to Ockham’s Razor, and that Ockham’s Razor should not be applied to irreducible normativity. This is because the appeal to Ockham’s Razor always contains an intractable element of epistemic circularity; and if this circularity is not vicious, we can construct a sound argument for the existence of (...) irreducibly normative truths that contains a similar kind of epistemic circularity. This argument is a version of Pascal’s Wager which I call “Parfit’s Wager,” because it is based on a passage from Derek Parfit’s On What Matters. It states that, if we believe that there are some irreducibly normative truths, we are more likely to be believing what we ought to believe compared to not believing that there are such truths, and that this indicates that we ought rationally to believe that there are such truths, justifying the ontological commitment to irreducible normativity in the process.

Jonas Olson presents a critical survey of moral error theory, the view that there are no moral facts and so all moral claims are false. Part I explores the historical context of the debate; Part II assesses J. L. Mackie's famous arguments; Part III defends error theory against challenges and considers its implications for our moral thinking.

Speech and thought about what the law is commonly function in practical ways, to guide or assess behavior. These functions have often been seen as problematic for legal positivism in the tradition of H.L.A. Hart. One recent response is to advance an expressivist analysis of legal statements (Toh), which faces its own, familiar problems. This paper advances a rival, positivist-friendly account of legal statements which we call “quasi-expressivist”, explicitly modeled after Finlay’s metaethical theory of moral statements. This consists in a (...) descriptivist, “rule-relational” semantics combined with a pragmatic account of the expressive and practical functions of legal discourse. We argue that this approach is at least as well-equipped as expressivism to explain the motivational and prescriptive features of “internal” legal statements, as well as a fundamental kind of legal disagreement, while being better positioned to account for various “external” uses of the same language. We develop this theory in a Hartian framework, and in the final part of the paper argue (particularly against Toh’s expressivist interpretation) that Hart’s own views in The Concept of Law are best reconstructed along such quasi-expressivist lines.

What is it that we are doing when we make ethical claims and judgments, such as the claim that we morally ought to assist refugees? This dissertation introduces and defends a novel theory of ethical thought and discourse. I begin by identifying the surface features of ethical thought and discourse to be explained, including the realist and cognitivist (i.e. belief-like) appearance of ethical judgments, and the apparent close connection between making a sincere ethical judgment and being motivated to act on (...) it. I examine prominent attempts to explain these features, with a focus on recent ‘hybrid’ theories combining elements of expressivism and cognitivism. Despite their initial promise, I argue that extant hybrid theories are nevertheless committed to problematic semantic, metasemantic, or pragmatic assumptions. I then discuss what I take to be the strongest existing option, ethical neo-expressivism (Bar-On and Chrisman, 2009; Bar-On, Chrisman, and Sias, 2014), and develop it into an explicitly hybrid theory proposing that ethical judgments incorporate both motivationally-charged affective states and moral beliefs. I then supplement this account with a theory of the proper function (following Millikan, 1984) of ethical claims and judgments, arguing that they function simultaneously to track the morally salient features of social situations, and to coordinate our behavior around these features. Finally, I defend one of the cognitivist commitments of the theory – namely, that objective moral knowledge is possible – by applying recent work on the epistemology of fundamental or ‘core’ intellectual commitments (Lynch, 2012; Pritchard, 2016) to the moral realm.

Secondo la teoria dell’errore tutte le proposizioni morali sono false poiché non si riferiscono ad alcun referente nel mondo. Se tale metaetica fosse corretta, dovremmo abbandonare il pensiero morale o continuare come nulla fosse? Come vivremmo se nelle nostre scelte non tenessimo conto di alcuna considerazione morale? L’abolizionismo morale argomenta che le nostre vite risulterebbero essere migliori, e perciò tenta di persuaderci a eliminare le pratiche morali. Questo contributo presenta un’introduzione critica al progetto abolizionista, indagandone le ragioni e mettendone in (...) luce le difficoltà. L’abolizionismo morale verrà collocato all’interno di una più ampia cornice metaetica e quindi confrontato con il finzionalismo e il conservazionismo morale. Infine, verrà esaminata la distinzione tra abolizionismo morale assertivo e non-assertivo. (shrink)

The central question for this dissertation is, how do we do moral philosophy well from within a broadly naturalist framework? Its main goal is to lay the groundwork for a methodological approach to moral philosophy that integrates traditional, intuition-driven approaches to ethics with empirical approaches that employ empirical data from biology and cognitive science. Specifically, it explores what restrictions are placed on our moral theorizing by findings in evolutionary biology, psychology, neuroscience, and other fields, and how we can integrate this (...) data while still offering a fully normative account of ethics. To that end, the dissertation explores the methodological assumptions behind both traditional and more empirical or experimental approaches to ethics, to find where these assumptions cannot be properly supported and need to be re-examined. Chapter 1 explores the science-based objections that have been raised to traditional approaches, with a particular focus on questions concerning the reliability of moral intuitions. Chapter 2 examines three fundamental assumptions supporting the empirical approach to moral philosophy, and how those assumptions ultimately do not fit with how we ought to understand the project of ethics. In chapter 3, I discuss the fact/value distinction, and the restrictions that are placed on our moral theorizing by our commitment to this distinction. Chapter 4 offers a defense of ‘companions in guilt’ arguments, and uses these arguments to draw an analogy between moral philosophy and epistemology that will be used to help defend moral philosophy against empirical debunking arguments. Chapter 5 explores the ways in which epistemologists’ methods of incorporating empirical data into their research while maintaining the normativity of their accounts can be adapted to allow moral philosophers to do the same, and brings together the various methodological concerns addressed up to this point to lay out a methodological approach I call empirically-informed moral philosophy.

Moral error theorists argue that moral thought and discourse are systematically in error, and that nothing is, or can ever be, morally permissible, required or forbidden. I begin by discussing how error theorists arrive at this conclusion. I then argue that if we accept a moral error theory, we cannot escape a pressing problem – what should we do next, metaethically speaking? I call this problem the ‘what now?’ problem, or WNP for short. I discuss the attempts others have made (...) to respond to the WNP, and in each case I show that the responses fail to be satisfying. I then propose a new response to the WNP, which I call revolutionary relativism. I define revolutionary relativism, explain why it is preferable to the existing responses to the WNP, and defend it against the most problematic objections I anticipate that opponents might raise. I conclude that revolutionary relativism succeeds where previous WNP responses fail, and that if we accept a moral error theory, we should become revolutionary relativists. (shrink)

Moral error theorists often claim to be strongly anti‑metaphysical in their moral scepticism and atheistic naturalists. This paper argues that pre‑ cisely this becomes a problem for them, when their metaethical and ontologi‑ cal commitments clash. I first outline how the known arguments against error theory face a problematic, yet rarely considered trade‑off : either they are very strong, then they are also very demanding in their assumptions or they are less demanding in their assumptions but rather weak in their (...) conclusions. In re‑ sponse to this challenge I then develop a new argument against error theory that exploits an overlooked inconsistency in the error theorists’ standard line of argumentation. I conclude that the implications of this inconsistency are less of a problem for fictionalist error theorists, but will render any eliminativism based on error theory circular. (shrink)

This thesis focuses on the evolution of human social norm psychology. More precisely, I want to show how the emergence of our distinctive capacity to follow social norms and make social normative judgments is connected to the lineage explanation of our capacity to form shared intentions, and how such capacity is related to a diverse cluster of prototypical moral judgments. I argue that in explaining the evolution of this form of normative cognition we also require an understanding of the developmental (...) trajectory of this capacity. For this purpose, the thesis is organized as follow. In the first chapter, I make some methodological remarks and provide the general overview and plan for the dissertation. In the second chapter, I explain what my explanatory target is and why it matters. On the view I am defending, shared intentional psychology gives rise to a special form of psychology that enables us to engage in social normative thinking. These norms are represented as shared intentional states. Moral psychology, in contrast, is more diverse. For moral judgments define a quite heterogeneous class of mental states—although some moral judgments may involve the representation and execution of norms, certainly not all of them do. I show that although much of our distinctive social norm psychology can be explained within the framework of shared intentionality, moral judgments cannot be unified in the same way. In the third chapter, I provide the baseline of social-cognitive capacities that serve as starting point for my lineage explanation. I argue that hominin social cognition was for a very long period of our evolutionary history essentially a matter of low-level cognitive and motivational processes. On this picture, bottom-up affective processes regulated the social lives of early hominins without requiring any special top-down mechanism of normative thinking such as a capacity for understanding and representing social norms. In the fourth chapter, I argue that human-like social norm psychology evolved as a result of the selective pressures that gave rise to shared intentionality, especially the demands that came from collective hunting. Yet collective hunting was not the whole story of the evolution of shared intentionality, for our capacity to form shared intentional mental states emerged from the interplay between the selective pressures that led to cooperative breeding in humans as well as organized, goal-oriented, collective hunting. Thus, I propose an evo-devo account of shared intentionality and its normative dimension since I argue that explaining the evolution of this particular form of normative thinking crucially depends on information about the developmental trajectory of this capacity. Finally, in the fifth chapter, I focus on how social norms are acquired and how the way we learn them gives rise to some prototypical cluster of moral judgments. Thus, this chapter returns to some of themes and arguments of the first chapter by explaining how the distinction between moral judgments and nonmoral judgments can be culturally transmitted. (shrink)
