Endurantist and perdurantist accounts of persistence

In this paper, I focus on three issues intertwined in current debates between endurantists and perdurantists—(i) the dimension of persisting objects, (ii) whether persisting objects have timeless, or only time-relative, parts, and (iii) whether persisting objects have proper temporal parts. I argue that one standard endurantist position on the first issue is compatible with standard perdurantist positions on parthood and temporal parts. I further argue that different accounts of persistence depend on the claims about objects’ dimensions and not on the auxiliary claims about parthood and temporal parts.     

A Quintet,a Quartet,a Trio,a Duo? The Epistemic Regress Problem,Evidential Support,and Skepticism

In his topical article, Andrew Cling claims that the best extant formulation of the so-called epistemic regress problem rests on five assumptions that are too strong. Cling offers an improved version that rests on a different set of three core epistemic assumptions, each of which he argues for. Despite of owing a great deal to Cling’s ideas, I argue that the epistemic regress problem surfaces from more fundamental assumptions than those offered by Cling. There are ultimately two core assumptions—in fact two contradictory strands within the concept of epistemic support—which jointly create a powerful challenge for our pursuit of paramount epistemic values.

Remembering (Short-Term) Memory: Oscillations of an Epistemic Thing

This paper provides an interpretation of Hans-J?rg Rheinberger’s notions of epistemic things and historical epistemology. I argue that Rheinberger’s approach articulates a unique contribution to current debates about integrated HPS, and I propose some modifications and extensions of this contribution. Drawing on examples from memory research, I show that Rheinberger is right to highlight a particular feature of many objects of empirical research (“epistemic things”)—especially in the contexts of exploratory experimentation—namely our lack of knowledge about them. I argue that this analysis needs to be supplemented with an account of what scientists do know, and in particular, how they are able to attribute rudimentary empirical contours to objects of research. These contours are closely connected to paradigmatic research designs, which in turn are tied to basic methodological rules for the exploration of the purported phenomena. I suggest that we engage with such rules in order to develop our own normative (epistemological) categories, and I tie this proposal to the idea of a methodological naturalism in philosophy of science.     

The epistemological challenge to metanormative realism: how best to understand it,and how to cope with it

Metaethical—or, more generally, metanormative—realism faces a serious epistemological challenge. Realists owe us—very roughly speaking—an account of how it is that we can have epistemic access to the normative truths about which they are realists. This much is, it seems, uncontroversial among metaethicists, myself included. But this is as far as the agreement goes, for it is not clear—nor uncontroversial—how best to understand the challenge, what the best realist way of coping with it is, and how successful this attempt is. In this paper I try, first, to present the challenge in its strongest version, and second, to show how realists—indeed, robust realists—can cope with it. The strongest version of the challenge is, I argue, that of explaining the correlation between our normative beliefs and the independent normative truths. And I suggest an evolutionary explanation (of a pre-established harmony kind) as a way of solving it.     

Human knowledge and the infinite progress of reasoning

The purpose of this paper is to explain how infinitism—the view that reasons are endless and non-repeating—solves the epistemic regress problem and to defend that solution against some objections. The first step is to explain what the epistemic regress problem is and, equally important, what it is not. Second, I will discuss the foundationalist and coherentist responses to the regress problem and offer some reasons for thinking that neither response can solve the problem, no matter how they are tweaked. Then, I want to present the infinitist solution to the problem and defend it against some of the well known objections to it.     

Feyerabend, Pseudo-Dionysius, and the Ineffability of Reality

This paper explores the influence of the fifth-century Christian Neoplatonist Pseudo-Dionysius the Areopagite (Denys) on the twentieth-century philosopher of science Paul Feyerabend. I argue that the later Feyerabend took from Denys a metaphysical claim—the ‘doctrine of ineffability’—intended to support epistemic pluralism. The paper has five parts. Part one introduces Denys and Feyerabend’s common epistemological concern to deny the possibility of human knowledge of ultimate reality. Part two examines Denys’ arguments for the ‘ineffability’ of God as presented in On the Divine Names. Part three then explores how Feyerabend imported Denys’ account of divine ineffability into his own metaphysics to provide a novel argument for epistemic pluralism. Part four explains the significance of an appreciation of Dionyius’ influence for our understanding of Feyerabend. I conclude that Denys was a significant and neglected influence upon the later Feyerabend.     

Internalist and externalist aspects of justification in scientific inquiry

While epistemic justification is a central concern for both contemporary epistemology and philosophy of science, debates in contemporary epistemology about the nature of epistemic justification have not been discussed extensively by philosophers of science. As a step toward a coherent account of scientific justification that is informed by, and sheds light on, justificatory practices in the sciences, this paper examines one of these debates—the internalist–externalist debate—from the perspective of objective accounts of scientific evidence. In particular, we focus on Deborah Mayo’s error-statistical theory of evidence because it is a paradigmatically objective theory of evidence that is strongly informed by methodological practice. We contend that from the standpoint of such an objective theory of evidence, justification in science has both externalist and internalist characteristics. In reaching this conclusion, however, we find that the terms of the contemporary debate between internalists and externalists have to be redefined to be applicable to scientific contexts.     

The Epistemological Roots of Ecclesiastical Claims to Knowledge

In theoretical matters, ecclesiastical claims to knowledge have lead to various conflicts with science. Claims in orientational matters, sometimes connected to attempts to establish them as a rule for legislation, have often been in conflict with the justified claims of non-believers. In addition they violate the Principle of Autonomy of the individual, which is at the very heart of European identity so decisively shaped by the Enlightenment. The Principle of Autonomy implies that state legislation should not interfere in the life of individual citizens, as long as his or her actions do not violate the rights of others. This paper—using the example of the theory of evolution—rejects ecclesiastical claims to theoretical knowledge as completely unfounded and preposterous. In the case of orientational knowledge—using the example of euthanasia—ecclesiastical claims to (universalizable) knowledge are shown to be unfounded as well. The Church’s position with respect to euthanasia and a range of other bio-ethical topics, such as pre-marital sex, contraception, abortion, indissolubility of marriage, and homosexuality, rests on a very peculiar ethical position. This ethical position is the natural right theory, which—far from being universalizable—is shared by very few people. Among other things, this position presupposes the belief in God as the creator of nature, and the assumption that ethical norms can be derived from this premise. Thus ecclesiastical knowledge claims, cannot be justified in a way which could be reasonably supposed to be universally acceptable. Kant (see the quote) was the first to require this sort of justification. Claims that fail to implement Kant’s stipulations should be eliminated by what I would like to call “Kant’s razor”.     

Relational and Substantival Ontologies, and the Nature and the Role of Primitives in Ontological Theories

Several metaphysical debates have typically been modeled as oppositions between a relationist approach and a substantivalist approach. Such debates include the Bundle Theory and the Substratum Theory about ordinary material objects, the Bundle (Humean) Theory and the Substance (Cartesian) Theory of the Self, and Relationism and Substantivalism about time. In all three debates, the substantivalist side typically insists that in order to provide a good treatment of the subject-matter of the theory (time, Self, material objects), it is necessary to postulate the existence of a certain kind of substance, while the other side, the relationist one, characteristically feels that this is an unnecessary expense and that one can get the job done in an ontologically cheaper way just with inter-related properties or events. In this paper I shall defend the view that there is much less of a disagreement between relational ontologies and substantival ontologies than it is usually thought. I believe that, when carefully examined, the two sides of the debate are not that different from each other, in all three cases of pairs of views mentioned above. As we will see, both the relational side and the substantival side work in the same way, suffer from and answer the same objections, and are structurally extremely similar. It will be an important question—one that I shall discuss in detail, and that is indeed the main point of interest for me in this paper—whether this means that the two sides of the debate are somehow ‘equivalent’ or not, and what ‘equivalent’ could mean.     

Metaethical Internalism: Another Neglected Distinction

‘Internalism’ is used in metaethics for a cluster of claims which bear a family resemblance. They tend to link, in some distinctive way—typically modal, mereological, or causal—different parts of the normative realm, or the normative and the psychological. The thesis of this paper is that much metaethical mischief has resulted from philosophers’ neglect of the distinction between two different features of such claims. The first is the modality of the entire claim. The second is the relation between the items specified in the claim. In part one I explain this distinction and the problems neglecting it may cause. In part two I show that it has been neglected, and has caused those problems, at least with respect to one version of internalism. That is judgment internalism, which claims that moral beliefs are necessarily related to pro- or con-attitudes; e.g., that if you believe you ought to x you must have some motivation to x. The considerations standardly adduced in favor of judgment internalism support only a version which lacks the metaethical implications typically attributed to it, at least so far as anyone has shown. Proponents and opponents of judgment internalism fail to realize this because of their neglect of the modality/relation distinction. I illustrate by considering discussions of judgment internalism by Russ Shafer-Landau, Simon Blackburn, James Dreier, David Brink, and others.

The Epistemic Norm of Blame

In this paper I argue that it is inappropriate for us to blame others if it is not reasonable for us to believe that they are morally responsible for their actions. The argument for this claim relies on two controversial claims: first, that assertion is governed by the epistemic norm of reasonable belief, and second, that the epistemic norm of implicatures is relevantly similar to the norm of assertion. I defend these claims, and I conclude by briefly suggesting how this putative norm of blame can serve as the basis for general norms of interpersonal generosity.     

The unity of hallucinations

My primary aim in this article is to provide a philosophical account of the unity of hallucinations, which can capture both perceptual hallucinations (which are subjectively indistinguishable from perceptions) and non-perceptual hallucinations (all others). Besides, I also mean to clarify further the division of labour and the nature of the collaboration between philosophy and the cognitive sciences. Assuming that the epistemic conception of hallucinations put forward by M. G. F. Martin and others is largely on the right track, I will focus on two main tasks: (a) to provide a satisfactory phenomenology of the subjective character of perceptions and perceptual hallucinations and (b) to redress the philosophers’ neglect of non-perceptual hallucinations. More specifically, I intend to apply one of the central tenets of the epistemic conception—that hallucinations can and should be positively characterised in terms of their phenomenological connections to perceptions—to non-perceptual hallucinations as well. That is, I will try to show that we can positively specify the class of non-perceptual hallucinations by reference to the distinctive ways in which we first-personally experience them and perceptions in consciousness. The task of saying more about their underlying third-personal nature may then be left to the cognitive sciences.     

Bonjour, Externalism and The Regress Problem*

In this paper I assess the two central ingredients of Laurence BonJour’s position on empirical knowledge that have survived the transition from his earlier coherentist views to his current endorsement of the doctrine of the given: his construal of the problem of the epistemic regress and his rejection of an internalist solution to the problem. The bulk of the paper is devoted to a critical assessment of BonJour’s arguments against externalism. I argue that they fail to put real pressure on externalism, as they rely on a highly questionable conception of epistemic rationality and responsibility. Then, more briefly, I take issue with BonJour’s endorsement of the irrelevance thesis—the claim that even if externalism were true it would not offer a satisfactory solution to the epistemic regress problem. I contend that he is not entitled to subscribe this thesis unless he is prepared to abandon his construal of the problem. *I have presented some of this material at UCL, Trinity College Dublin and the 10th Italo-Spanish meeting of Analytic Philosophy, held in Pamplona. I am grateful to these audiences.     

Stance,feeling and phenomenology

This paper addresses Bas van Fraassen’s claim that empiricism is a ‘stance’. I begin by distinguishing two different kinds of stance: an explicit epistemic policy and an implicit way of ‘finding oneself in a world’. At least some of van Fraassen’s claims, I suggest, refer to the latter. In explicating his ordinarily implicit ‘empirical stance’, he assumes the stance of the phenomenologist, describing the structure of his commitment to empiricism without committing to it in the process. This latter stance does not incorporate the attitude that van Fraassen takes to be characteristic of empiricism. Thus its possibility serves to illustrate that empiricism as an all-encompassing philosophical orientation is untenable. I conclude by discussing the part played by feelings in philosophical stances and propose that they contribute to philosophical conviction, commitment and critique.     

A dilemma for internalism?

Internalism about epistemic justification (henceforth, ‘internalism’) says that a belief B is epistemically justified for S only if S is aware of some good-making feature of B, some feature that makes for B’s having positive epistemic status: e.g., evidence for B. Externalists with respect to epistemic justification (‘externalists’) deny this awareness requirement. Michael Bergmann has recently put this dilemma against internalism: awareness admits of a strong and a weak construal; given the strong construal, internalism is subject to debilitating regress troubles; given the weak construal, internalism is unmotivated; either way, internalism is in serious trouble. I argue for two claims in this article. First, Bergmann’s dilemma argument is unmotivated: he’s given no good reason for accepting one of its crucial premises. And second, Bergmann’s dilemma argument is unsound: the crucial premise in question is false.     

New surprises for the Ramsey Test

In contemporary discussions of the Ramsey Test for conditionals, it is commonly held that (i) supposing the antecedent of a conditional is adopting a potential state of full belief, and (ii) Modus Ponens is a valid rule of inference. I argue on the basis of Thomason Conditionals (such as ‘If Sally is deceiving, I do not believe it’) and Moore’s Paradox that both claims are wrong. I then develop a double-indexed Update Semantics for conditionals which takes these two results into account while doing justice to the key intuitions underlying the Ramsey Test. The semantics is extended to cover some further phenomena, including the recent observation that epistemic modal operators give rise to something very like, but also very unlike, Moore’s Paradox.     

The Invincible Summer: On Albert Camus’ Philosophical Neoclassicism

What follows is a work of critical reconstruction of Camus' thought. It aims to answer to the wish Camus expressed in his later notebooks, that he at least be read closely. Specifically, I hope to do three things. In Part I, we will show how Camus' famous philosophy of the absurd represents a systematic scepticism whose closest philosophical predecessor is Descartes' method of doubt, and whose consequence, as in Descartes, is the discovery of a single, orienting certainty, on the basis of which Camus would proceed to pass beyond the 'nihilism' that conservative critics continued to level against him (MS 34). Part II will unfold the central tenets of Camus' mature thought of rebellion, and show how Camus' central political claims follow from his para-Cartesian claim to have found an irreducible or 'invincible' basis for a post-metaphysical ethics, consistent with the most thoroughgoing epistemic scepticism. Part III then undertakes to show that the neoclassical rhetoric and positioning Camus claimed for his postwar thought—as a thought of moderation or mesure, and a renewed Greek or Mediterranean naturalism—is more than a stylistic pretension. It represents, so I argue, a singular amalgam of modern and philosophical classical motifs which makes Camus' voice nearly unique in twentieth century ideas, and all the more worth reconsidering today. So let us proceed.     

Advice for fallibilists: put knowledge to work

We begin by asking what fallibilism about knowledge is, distinguishing several conceptions of fallibilism and giving reason to accept what we call strong epistemic fallibilism, the view that one can know that something is the case even if there remains an epistemic chance, for one, that it is not the case. The task of the paper, then, concerns how best to defend this sort of fallibilism from the objection that it is “mad,” that it licenses absurd claims such as “I know that p but there’s a chance that not p” and “p but it there’s a chance that not p.” We argue that the best defense of fallibilism against this objection—a “pragmatist” defense—makes the following claims. First, while knowledge that p is compatible with an epistemic chance that not-p, it is compatible only with an insignificant such chance. Second, the insignificance of the chance that not-p is plausibly understood in terms of the irrelevance of that chance to p’s serving as a ‘justifier’, for action as well as belief. In other words, if you know that p, then any chance for you that not p doesn’t stand in the way of p’s being properly put to work as a basis for action and belief.

Similarity, alignment, and conceptual combination: Comment on Estes and Glucksberg

In their paper “Interactive Property Attribution in Concept Combination,” Estes and Glucksberg (2000) suggest an alternative to the alignment view of property interpretation— one based on salience and relevance of features. I suggest that alignment as well as feature salience and relevance are crucial to property interpretation. In making their claims, Estes and Glucksberg also assume that similarity has inverse effects on two important ways of interpreting combinations (i.e., property and relation interpretations). I show that this assumption does not generally hold and provide an alternative explanation for their results (one based on the plausibility of relation interpretations).     

How to prove that some acts are wrong (without using substantive moral premises)

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.
