Foundationalism in moral epistemology is a core tenet of ethical intuitionism. According to foundationalism, some moral beliefs can be known without inferential justification; instead, all that is required is a proper understanding of the beliefs in question. In an influential criticism against this view, Walter Sinnott-Armstrong has argued that certain psychological facts undermine the reliability of moral intuitions. He claims that foundationalists would have to show that non-inferentially justified beliefs are not subject to those defeaters, but this would already constitute (...) a form of inference and hence undermine the possibility of noninferential justification. The goal of my paper is to defend foundationalism against Sinnott-Armstrong’s criticism. After presenting his challenge, I first argue that the most promising objection to it fails. This objection makes the case that defeater-defeaters are not part of the justification, but merely preserve the justification which the original claim provides. I object to this argument by distinguishing between weak and robust defeaters; only weak defeaters, I argue, fall outside the scope of justification, and it is an open question whether Sinnott-Armstrong’s defeaters fall into that category. This leads the way to my own criticism of Sinnott-Armstrong’s challenge: foundationalists in moral epistemology are entitled to the use of defeater-defeaters as part of the justification for moral beliefs as long as those defeater-defeaters themselves do not entail moral claims. Therefore, Sinnott-Armstrong’s challenge does not undermine foundationalism. (shrink)

In moral epistemology, the method of reflective equilibrium is often characterized in terms of intuitions or understood as a method for justifying intuitions. An analysis of reflective equilibrium and current theories of moral intuitions reveals that this picture is problematic. Reflective equilibrium cannot be adequately characterized in terms of intuitions. Although the method presupposes that we have initially credible commitments, it does not presuppose that they are intuitions. Nonetheless, intuitions can enter the process of developing a reflective equilibrium and, if (...) the process is successful, be justified. Since the method of reflective equilibrium does not essentially involve intuitions, it does not constitute a form of intuitionism in any substantial sense. It may be classified as intuitionist only in the minimal sense of not reducing justification to a matter of inference relations alone. (shrink)

Walter Sinnott-Armstrong argues that moral disagreement and widespread moral bias pose a serious problem for moral intuitionism. Seneca’s view that we just recognise the good could be criticised using a similar argument. His approach to argumentation offers a way out, one that may serve as a model for a revisionary intuitionism.

In moral psychology, “psychological rationalism” is the view that moral judgments are caused by a process of reasoning. Jonathan Haidt argues against this view by showing that people succumb to “moral dumbfounding”—they cannot adequately provide reasoning for their moral judgment. I argue that this evidence undermines psychological rationalism only if the view is committed to two claims about reasoning: (a) reasoning must meet an adequacy condition, and (b) reasoning must be sufficiently conscious. I argue that plausible variants of psychological rationalism (...) are not committed to these requirements. Thus, the efficacy of the dumbfounding objection is more limited than it might initially seem. (shrink)

Non-naturalist normative realists face an epistemological objection: They must explain how their preferred route of justification ensures a non-accidental connection between justified moral beliefs and the normative truths. One strategy for meeting this challenge begins by pointing out that we are semantically or conceptually competent in our use of the normative terms, and then argues that this competence guarantees the non-accidental truth of some of our first-order normative beliefs. In this paper, I argue against this strategy by illustrating that this (...) competence based strategy undermines the non-naturalist’s ability to capture the robustly normative content of our moral beliefs. (shrink)

Walter Sinnott-Armstrong has argued against moral intuitionism, according to which some of our moral beliefs are justified without needing to be inferred from any other beliefs. He claims that any prima facie justification some non-inferred moral beliefs might have enjoyed is removed because many of our moral beliefs are formed in circumstances where either (1) we are partial, (2) others disagree with us and there is no reason to prefer our moral judgement to theirs, (3) we are emotional in a (...) way that clouds our judgement, (4) the circumstances are conducive to illusion, or (5) the source of our moral beliefs is unreliable or disreputable. I take issue with the elements of Sinnott-Armstrong’s argument that centre on (1) to (3) and (5), concluding that his case against moral intuitionism is unpersuasive. (shrink)

A central metaphilosophical project seeks to evaluate the reliability of the types of evidence that figure in philosophical arguments and, relatedly, the justificatory status of relying on those types of evidence. Traditionally, metaphilosophers have approached this project via an analysis of intuition. This article argues that the category picked out by “intuition” is both too broad and too heterogeneous to serve as the appropriate target for metaphilosophical inquiry. Intuition is a gerrymandered and disjunctive kind, undeserving of the widespread attention it (...) receives in the literature. Instead, metaphilosophers should examine more finely grained mental states. Three promising strategies for parsing intuitions more finely are proposed: by their causal origins, by their context of employment, and by the exoticism of their content. This more narrow focus may significantly alter the dialectic in three prominent metaphilosophical arguments: the argument from calibration, the argument from self-defeat, and the argument from intuitional sensitivity.

Learning the psychological origins of our moral judgments can lead us to lose confidence in them. In this paper I explain why. I consider two explanations drawn from existing literature—regarding epistemic unreliability and automaticity—and argue that neither is fully adequate. I then propose a new explanation, according to which psychological research reveals the extent to which we are disturbingly disunified as moral agents.

Recent empirical work appears to suggest that the moral intuitions of professional philosophers are just as vulnerable to distorting psychological factors as are those of ordinary people. This paper assesses these recent tests of the ‘expertise defense’ of philosophical intuition. I argue that the use of familiar cases and principles constitutes a methodological problem. Since these items are familiar to philosophers, but not ordinary people, the two subject groups do not confront identical cognitive tasks. Reflection on this point shows that (...) these findings do not threaten philosophical expertise—though we can draw lessons for more effective empirical tests. (shrink)

Reflective equilibrium has been criticized for various reasons ever since the publication of Rawls’ A Theory of Justice. Recent empirical research into moral decision-making poses new challenges to RE because it questions the reliability of moral intuitions. This research might discredit moral intuitionism in general and RE in particular insofar as it ascribes epistemic value to moral intuitions. These findings suggest, for instance, that moral intuitions vary with cultural background, gender or framing. If it could be shown that all or (...) certain kinds of moral intuitions are unreliable, this would diminish the plausibility of the claim that they provide good reasons to believe in the truth of their content, especially given the growing evidence that professional philosophers are just as biased and susceptible to distorting factors as lay people. In this paper I critically discuss three recent defenses of RE against this unreliable intuitions objection. Two of these defenses argue that the UIO misses its target, because RE does not depend on intuitions, or because the relevant considered judgments in RE are not intuitions. The third defense grants that RE depends on intuitions and that some Rawlsian considered judgments are intuitions. But it argues that the notion of considered judgments can be revised, and that wide reflective equilibrium has the means to adopt the criticism because it can use information about unreliable intuitions and exclude those from further consideration. I argue that the first two defenses do not succeed. The third defense is the most promising one. However, I argue that this defense also fails. In this defense, RE is not a distinctive moral epistemic theory: different versions of RE would be conceivable, all of which are deeply problematic. I conclude with a discussion of the broader philosophical implications of the UIO, specifically whether or not accepting the UIO would warrant skepticism regarding moral knowledge. (shrink)

Those who I call meta-skeptics in my paper argue that one should suspend judgment about every philosophical question. Most often they use the argument from disagreement to show that the suspension of our philosophical beliefs is our epistemic obligation. In the present paper I argue against the main motivation for this view and show that since even the meta-skeptics’ stance is a contested philosophical one, their argument cannot succeed without refuting itself. Various meta-skeptics proposed counterobjections to this self-refutation objection. I (...) consider here Jason Brennan’s quite simple and Bryan Frances’s more sophisticated counter-objections. Their proposals are even more interesting because they differ from the typical points of meta-skeptics: Brennan argues for outsider skepticism, that is non-philosophers should suspend judgment about philosophical issues, and Frances relies on the notion of epistemic superior instead of epistemic peer. I consider their points in two ways: whether their counter-objections can help regular meta-skepticism and whether their skepticism can stand on its own. In my replies to these proposals I show why both are problematic in each of these two ways. Brennan says that widespread disagreement is a sign of philosophy’s unreliability. Yet, he can only address the charge that his point is a philosophical one and not the objection that there can be disagreement about it. And since there is good reason to think that even his position is subject to disagreement, it is self-undermining. Furthermore, Brennan does not give any reason why any first-order philosophical theory must lack the virtues that his argument displays. Frances argues that even if the argument from disagreement is self-refuting and meta-skeptics have to suspend judgment about it, they might still remain skeptics after all. In my reply I show how Frances’s defense of his position still relies on principles that could be the objects of further arguments from disagreement. (shrink)

In this article, I discuss whether intuitive moral judgements have epistemic value. Are they mere expressions of irrational feelings that should be disregarded or should they be taken seriously? In section 2, I discuss the view of some social psychologists that moral intuitions are, like other social intuitions, under certain conditions more reliable than conscious deliberative judgements. In sections 3 and 4, I examine whether intuitive moral judgements can be said not to need inferential justification. I outline a concept of (...) moral intuition as a seeming whose seemingness resides in special, phenomenological features such as a felt veridicality, appropriateness, familiarity, or confidence, and whose justificatory force is influenced by the reliability of the belief-producing procedures and by a subject's competence in applying moral concepts. I argue that subjects can come to realise that the beliefs expressed in their intuitive judgements evoke a sense of non-inferential credibility. In section 5, I first discuss the contribution of moral expertise to the non-inferential credibility of a person's intuitions. Subsequently, I discuss whether Walter Sinnott-Armstrong is right in saying that we can never claim non-inferential justification for our intuitions because they are subject to all kinds of distorting influences.

In this article, I propose, defend, and apply a principle for applied ethics. According to this principle, we should exercise moral caution, at least when we can. More formally, the principle claims that if you should believe or suspend judgment that doing an action is a serious moral wrong, while knowing that not doing that action is not morally wrong, then you should not do that action. After motivating this principle, I argue that it has significant application in applied ethics. (...) The application to applied ethics comes by way of the epistemic significance of disagreement. Though such a principle has perhaps a number of applications in applied ethics, my focus here is limited to the question of whether it is morally permissible to eat animals for pleasure. (shrink)

Evolutionary Debunking Arguments purport to show that our moral beliefs do not amount to knowledge because these beliefs are “debunked” by the fact that our moral beliefs are, in some way, the product of evolutionary forces. But there is a substantial gap in this argument between its main evolutionary premise and the skeptical conclusion. What is it, exactly, about the evolutionary origins of moral beliefs that would create problems for realist views in metaethics? I argue that evolutionary debunking arguments are (...) best understood as offering up defeaters for our moral beliefs. Moreover, the defeater in question is a paradigmatic instance of undercutting defeat. If anything is an undercutting defeater, then learning about the evolutionary origins of our moral beliefs is a defeater for those beliefs. (shrink)

What kinds of mental states can be based on epistemic reasons? The standard answer is only beliefs. I argue that perceptual states can also be based on reasons, as the result of crossmodal interactions. A perceptual state from one modality can provide a reason on which an experience in another modality is based. My argument identifies key markers of the basing relation and locates them in the crossmodal Marimba Illusion (Schutz & Kubovy 2009). The subject’s auditory experience of musical tone (...) duration is based on the reason provided by her visual representation of the length of the musician’s gesture and other stored perceptual principles.

In this article, various objections will be discussed that have been put forward against ethical relativism, but which haven’t been considered seriously enough on the part of relativists and have been overrated on the part of their opponents. The objections will be concentrated into three arguments: the action-theoretic, the epistemological and the truth-theoretic argument. The article will discuss whether they can be rebutted by proponents of the two main types of relativism: indexical relativism and truth-relativism. The conclusion will be as (...) follows: one version of indexical relativism, the analytical version, gets into serious troubles by the action-theoretic argument, while its revisionary version will remain unaffected, the epistemological argument fails with respect to indexical relativism and stands on shaky ground as regards truth-relativism, the truth-theoretic argument puts considerable pressure on truth-relativism.

The argument from faultless disagreement against moral realism is based on the alleged possibility of cognitively faultless moral disagreement, CFD. This possibility contradicts the pre-theoretic intuition that moral truth is knowable, in principle, the so-called epistemic constraint on moral truth, EC. In this paper, I discuss the realist’s two options to cope with this argument. First of all, I point out the realist’s strategies to explain the possibility of cognitively faultless error, which is implied by CFD. Then I discuss one (...) promising option to respond to the argument from faultless disagreement: accepting both CFD and EC but blocking the ensuing contradiction by invoking an equivocation as regards the notion of knowability. After pointing out the drawbacks of this solution I discuss the other promising option: rejecting CFD by drawing on an agnostic stance on the part of cognitively blameless thinkers as regards moral propositions they cannot agree on. Yet this option faces the problem that EC has to be denied. In concluding the paper, I outline the prospects of an attractive objectivist shape of moral antirealism, which is also affected by the argument from faultless disagreement. (shrink)

The present paper offers an analogical support for the use of rational intuition, namely, if we regard sense perception as a mental faculty that (in general) delivers justified beliefs, then we should treat intuition in the same manner. I will argue that both the cognitive marks of intuition and the role it traditionally plays in epistemology are strongly analogous to that of perception, and barring specific arguments to the contrary, we should treat rational intuition as a source of prima facie (...) justified beliefs. There are two main arguments against the intuition-perception analogy that I will consider and find lacking. First is that while we do use perceptions as evidence to believe certain propositions, in fact no one ever does use intuition evidentially. The second argument, stemming from experimental philosophy, grants that philosophers do use intuitions evidentially, but this practice is fatally unlike that of perception, in that perception yields warranted beliefs and intuition does not.

Jessy Giroux | : J’aborde dans cet article un problème que je nomme le « spectre épistocratique ». Le problème se présente ainsi : s’il existe des vérités politiques, c’est-à-dire des positions politiques qui soient véritablement bonnes, ne devrait-on pas faire de l’atteinte de ces vérités politiques l’objectif central de notre système politique, ce qui pourrait nous conduire à limiter le pouvoir populaire afin de laisser les individus « éclairés » prendre toutes les décisions politiques ? J’explore différentes stratégies possibles (...) afin de défendre la démocratie contre l’attrait d’une telle épistocratie, et je conclus que la meilleure stratégie consiste à souligner qu’une démocratie délibérative bien organisée démontre un potentiel épistémique supérieur à tout autre système politique.

I explore various possible strategies in order to defend democracy against the appeal of such an epistrocratic system, and I conclude that the best available strategy is one that emphasizes that a well-organized deliberative democracy possesses an epistemic potential that is superior to that of any other political system. I conclude by showing how this fact can inform our understanding of the phenomenon of political dissent. (shrink)

In this paper I lay out, argue for, and defend ethical Mooreanism. In essence, the view says that some moral propositions are Moorean propositions and thus are epistemically superior to the conjunctions of the premises of skeptical arguments to the contrary. In Sect. 1 I explain Mooreanism and then ethical Mooreanism. In Sect. 2 I argue for ethical Mooreanism by noting a number of important epistemic parities that hold between certain moral truths and standard Moorean facts. In Sect. 3 I (...) defend ethical Mooreanism against the objection that moral propositions are too epistemically dissimilar to standard Moorean facts to count as Moorean truths. (shrink)

In recent work, Bengson, Cuneo, and Shafer‐Landau (2020) develop a new social version of moral intuitionism that promises to explain why our moral intuitions are trustworthy. In this paper, we raise several worries for their account and present some general challenges for the broader class of views we call Social Moral Intuitionism. We close by reflecting on Bengson, Cuneo, and Shafer‐Landau's comparison between what they call the “perceptual practice” and the “moral intuition practice”, which we take to raise some difficult (...) normative and meta‐normative questions for theorists of all stripes.

Philosophy and Phenomenological Research, EarlyView.

For many of the moral beliefs we hold, we know that other people hold moral beliefs that contradict them. If you think that moral beliefs can be correct or incorrect, what difference should your awareness of others’ disagreement make to your conviction that you, and not those who think otherwise, have the correct belief? Are there circumstances in which an awareness of others’ disagreement should lead you to suspend a moral belief? If so, what are they, and why? This paper (...) argues that three principles, taken together, give us a good answer to these questions; that they license a form of provisional moral self-trust; and that they reveal an interestingly distinctive form of pragmatic encroachment in relation to the epistemic standards governing moral belief.

In recent years there has been a resurgence of interest in Ethical Intuitionism, whose core claim is that normal ethical agents can and do have non-inferentially justified first-order ethical beliefs. Although this is the standard formulation, there are two senses in which it is importantly incomplete. Firstly, ethical intuitionism claims that there are non-inferentially justified ethical beliefs, but there is a worrying lack of consensus in the ethical literature as to what non-inferentially justified belief is. Secondly, it has been overlooked (...) that there are plausibly different types of non-inferential justification, and that accounting for the existence of a specific sort of non-inferential justification is crucial for any adequate ethical intuitionist epistemology. In this context, it is the purpose of this paper to provide an account of non- inferentially justified belief which is superior to extant accounts, and, to give a refined statement of the core claim of ethical intuitionism which focuses on the type of non- inferential justification vital for a plausible intuitionist epistemology. Finally, it will be shown that the clarifications made in this paper make it far from obvious that two intuitionist accounts, which have received much recent attention, make good on intuitionism’s core claim.

What role, if any, does dialectic play in Aristotle’s epistemology in the Topics? In this paper I argue that it does play a role, but a role that is independent of endoxa. In the first section, I sketch the case for thinking that dialectic plays a distinctively epistemological role—not just a methodological role, or a merely instrumental role in getting episteme. In the second section, I consider three ways it could play that role, on two of which endoxa play at (...) least a co-starring role. But in the third section, I argue that endoxa don’t play that co-starring role, by arguing for a deflationary account of what endoxa are. For that reason, the third view emerges as the most plausible; but the third view is, I’ll suggest, Platonic. (shrink)

Moral intuitionism, which claims that some moral seemings are justification-conferring, has become an increasingly popular account in moral epistemology. Defenses of the position have largely focused on the standard account, according to which the justification-conferring power of a moral seeming is determined by its phenomenal credentials alone. Unfortunately, the standard account is a less plausible version of moral intuitionism because it does not take etiology seriously. In this paper, I provide an outline and defense of a non-standard account of moral (...) intuitionism that I dub the “Prudent Conscience View.” According to this view, phenomenal credentials only partially determine the justification-conferring power of a moral seeming, for a seeming’s justification-conferring power is also determined by its etiology. In brief, a moral seeming is justification-conferring to the degree that the conscience that gave rise to it is functioning properly, and a person's conscience functions properly to the degree that the person is prudent. (shrink)

According to moral intuitionism, at least some moral seeming states are justification-conferring. The primary defense of this view currently comes from advocates of the standard account, who take the justification-conferring power of a moral seeming to be determined by its phenomenological credentials alone. However, the standard account is vulnerable to a problem. In brief, the standard account implies that moral knowledge is seriously undermined by those commonplace moral disagreements in which both agents have equally good phenomenological credentials supporting their disputed (...) moral beliefs. However, it is implausible to think that commonplace disagreement seriously undermines moral knowledge, and thus it is implausible to think that the standard account of moral intuitionism is true.

Empirical research indicates that feelings of disgust actually affect our moral beliefs and moral motivations. The question is, should they? Daniel Kelly argues that they should not. More particularly, he argues for what we may call the irrelevancy thesis and the anti-moralization thesis. According to the irrelevancy thesis, feelings of disgust should be given no weight when judging the moral character of an action (or norm, practice, outcome, or ideal). According to the anti-moralization thesis, feelings of disgust should not be (...) allowed a role in, or harnessed in the service of, moral motivation. In this paper, I will argue against both theses, staking out a moderate position according to which feelings of disgust can (but needn’t always) play a proper role in aid of moral belief formation and moral motivation.

Here I examine the major theories of ethical intuitions, focusing on the epistemic status of this class of intuitions. We cover self-evidence theory, seeming-state theory, and some of the recent contributions from experimental philosophy.

Non-descriptivists in metaethics should say more about intuitions. For one popular theory has it that case-based intuitions are in the business of correctly categorizing or classifying merely by bringing to bear a semantic or conceptual competence. If so, then the fact that all normative predicates have case-based intuitions involving them shows that they too are in the business of categorizing or classifying things. This favors a descriptivist position in metaethics—normative predicates have descriptive content—and disfavors a purely non-descriptivist position, like pure (...) expressivism. However, we can say more. We can distinguish two different sorts of intuitional state, A-grade intuitions and B-grade intuitions, based on a cluster of properties that are distinctive of each. While a hypothesis about categorization best explains the cluster of properties enjoyed by A-grade intuitions, it does not best explain the cluster of properties enjoyed by B-grade intuitions. Indeed, a non-categorizational, attitude-expressive hypothesis about the relevant meanings best explains B-grade intuitions. And intuitions involving thin normative predicates are B-grade. So intuition theory supports non-descriptivism, not descriptivism, about thin normative predicates. (shrink)

Having no recourse to ways of knowing about the natural world, ethical non-naturalists are in need of an epistemology that might apply to a normative breed of facts or properties, and intuitionism seems well suited to fill that bill. Here I argue that the metaphysical inspiration for ethical intuitionism undermines that very epistemology, for this pair of views generates what I call the defeater from cosmic coincidence. Unfortunately, we face not a happy union, but a difficult choice: either ethical intuitionism (...) or ethical non-naturalism, but not both. (shrink)

In this paper, I introduce a new challenge to moral realism: the skeptical argument from moral underdetermination. The challenge arises as a consequence of two recent projects in normative ethics. Both Parfit and a group called consequentializers have independently claimed that the main traditions of normative theories can agree on the set of correct particular deontic verdicts. Nonetheless, as Dietrich and List :421–479, 2017) and myself :191–221, 2018; Australas J Philos 97:511–527, 2019; Ethical Theory Moral Pract 24:999–1018, 2021a) have argued, (...) the traditions still disagree about why these are the correct verdicts. This means that we can understand the situation in terms of an idea from the philosophy of science, the underdetermination of theory by the evidence. Yet underdetermination figures in one of the most important skeptical challenges to scientific realism. I show how an analogous skeptical argument can be construed for the moral realm. I propose a standard form for that argument. I then defend it against three possible objections, arguing that it is at least as plausible as, if not more plausible than, its counterpart in the philosophy of science. (shrink)

In this thesis, I will explore the epistemological evolutionary debunking arguments in meta-ethics. I will defend these arguments by accomplishing two tasks: I will offer the best way to understand the EDA and I will also respond to two strongest objections to the EDA. Firstly, in Part I of this thesis, I will offer my account of how the EDA should be best formulated. I will start from how evolution has significantly influenced our moral beliefs. I will then explain why, (...) due to their evolutionary origin, our moral beliefs are not tracking the moral truth reliably. Furthermore, I will argue that the fact that our moral beliefs are not tracking the moral truth also provides an undercutting and a higher-order defeater for those beliefs. As a result, I will conclude that the epistemic status of our moral beliefs is undermined because of these two kinds of defeaters. Secondly, in Part II of this thesis, I will turn my attention to the two strongest objections to the EDA – the Conceptual Truth Objection and the Third Factor Objection. I will first offer two responses to the Conceptual Truth Objection and, based on these two responses, I will argue that the Conceptual Truth Objection fails as a challenge to the EDA. I will then also argue that there currently doesn’t exist an acceptable version of the Third Factor Objection and it is also unlikely that such a version could be constructed in the future. I will finally conclude that both objections are problematic and they are thus unable to give us reason to doubt the EDA. (shrink)

In this dissertation I discuss the epistemology of ethical intuitionism, in particular the claim that mature moral agents possess self-evident moral knowledge. Traditional intuitionists such as W.D. Ross have claimed that by reflection, we can acquire knowledge of our basic moral duties such as the duty of veracity or benevolence. Recent defenders of intuitionism such as Robert Audi have further developed this theory and argued that adequate understanding can be sufficient for moral knowledge. I criticize this view and argue that (...) such accounts fail to make a convincing case for a foundationalist moral epistemology. Instead, I propose to separate the question of how we acquire moral knowledge from an account that justifies moral beliefs. In response to the first issue, I draw an analogy between our moral intuitions and chosmkian linguistics; in both areas, I argue, human beings possess a universal, unconscious and (partly) inaccessible system of rules that explains how we come to learn language and to make moral judgments. In regards to the justificatory issue, I address recent evolutionary debunking arguments designed to undermine the claim that our moral judgments track stance-independent truths. I try to show that this conclusion only follows under the assumption of an instrumentalist interpretation of moral reasoning which the intuitionist is not forced to accept. (shrink)

I argue for three central theses: ‘intuition’ is ambiguous, in material object metaphysics ‘intuition’ refers to pre-theoretical beliefs, and these pre-theoretical beliefs are generated by an innate physical reasoning system. I begin by outlining the relevant background discussions on the nature of intuitions and their role in philosophy to motivate the need for a more careful investigation of the meaning of ‘intuition’ and the role of intuitions in specific sub-disciplines of philosophy. In chapters one and two I argue that ‘intuition’ (...) is ambiguous between an inflationary and deflationary sense. In the inflationary sense, ‘intuition’ refers to a priori intellectual seemings with a special phenomenology, conceptual etiology, and modal content. In the deflationary sense, ‘intuition’ refers to beliefs or inclinations to believe. In chapter three I specifically examine the use of intuitions in material object metaphysics and conclude that in this sub-community ‘intuition’ is used in the deflationary sense to refer to pre-theoretical beliefs. Drawing from research on infant cognition, in the final chapter I argue that intuitions regarding material object metaphysics are those judgments that arise from an innate physical reasoning system. Based on this empirical observation, I argue that metaphysicians ought to give preference to abstract intuitions over intuitions regarding concrete cases because these abstract intuitions reflect the innate structure of our physical reasoning mechanisms.
