According to moral error theory, morality is something invented, constructed or made; but mistakenly presents itself to us as if it were an independent object of discovery. According to moral constructivism, morality is something invented, constructed or made. In this paper I argue that constructivism is both compatible with, and in certain cases explanatory of, some of the allegedly mistaken commitments to which arguments for moral skepticism appeal. I focus on two particular allegations that are sometimes associated with moral skepticism. (...) The first is the suspicion that in making moral claims we are merely projecting our attitudes onto the world. The second is the suspicion that in arguing for and against moral views we are merely attempting to influence each other to give similar answers to questions that have no determinate answer.

Why did such highly abstract ideas as truth, knowledge, or justice become so important to us? What was the point of coming to think in these terms? This book presents a philosophical method designed to answer such questions: the method of pragmatic genealogy. Pragmatic genealogies are partly fictional, partly historical narratives exploring what might have driven us to develop certain ideas in order to discover what these do for us. The book uncovers an under-appreciated tradition of pragmatic genealogy which cuts (...) across the analytic-continental divide, running from the state-of-nature stories of David Hume and the early genealogies of Friedrich Nietzsche to recent work in analytic philosophy by Edward Craig, Bernard Williams, and Miranda Fricker. However, these genealogies combine fictionalizing and historicizing in ways that even philosophers sympathetic to the use of state-of-nature fictions or real history have found puzzling. To make sense of why both fictionalizing and historicizing are called for, the book offers a systematic account of pragmatic genealogies as dynamic models serving to reverse-engineer the points of ideas in relation not only to near-universal human needs, but also to socio-historically situated needs. This allows the method to offer us explanation without reduction and to help us understand what led our ideas to shed the traces of their practical origins. Far from being normatively inert, moreover, pragmatic genealogy can affect the space of reasons, guiding attempts to improve our conceptual repertoire by helping us determine whether and when our ideas are worth having.

In this paper, I consider some ways in which the Copy Principle and Hume’s nominalism impinge on one another, concluding that the marriage is not a happy one. I argue for the following claims. First, Hume’s argument against indeterminate ideas isn’t cogent even if the Copy Principle is accepted. But this does not vindicate Locke: the imagistic conception of ideas, presupposed by the Copy Principle, will force Locke to accept something like Hume’s view of the way general terms function, the (...) availability of abstract ideas notwithstanding. Second, Hume’s discussion of nominalism provides support for the “old Hume” interpretation, which takes the Copy Principle to be a criterion of meaningfulness, as against the “new Hume” reading, according to which it constrains what we can know. Finally, nominalism forces Hume to adopt a more complicated theory of ideas. (shrink)

In the section of the Treatise titled ‘Of the immateriality of the soul’, Hume adduces an argument to show that nothing can be ‘locally conjoined’ with all of a person’s perceptions. The argument is seldom discussed, and deserves attention, mainly because it can be transformed into an argument against the very existence of a soul. In this paper, I present and closely examine both arguments, Hume’s argument and the one against the existence of the soul. Both, I conclude, are fallacious. (...) In dem Abschnitt des Treatise mit dem Titel ‚Of the immateriality of the soul‘ bringt Hume ein Argument vor, das zeigen soll, dass nichts mit allen Perzeptionen einer Person ‚lokal verknüpft‘ sein kann. Das Argument wird selten diskutiert, verdient aber Aufmerksamkeit, hauptsächlich deshalb, weil es in ein Argument gegen die Existenz der Seele umgewandelt werden kann. In diesem Aufsatz stelle ich beide Argumente – Humes Argument und das gegen die Existenz der Seele – dar und untersuche sie im Detail. Ich gelange zu der Feststellung, dass beide Argumente fehlerhaft sind. (shrink)

The essay revisits the puzzle of the ‘passage’ of time in relation to EPR-type measurements and asks what philosophical consequences can be drawn from them. Some argue that the lack of invariance of temporal order in the measurement of a space-like related EPR pair, under relativistic motion, casts serious doubts on the ‘reality’ of the lapse of time. Others argue thatcertain features of quantum mechanics establisha tensed theory of time – understood here as Possibilism or the growing block universe. The (...) paper analyzes the employment of frame-invariant entropic clocks in a relativistic setting and argues that tenselessness does not imply timelessness. But this conclusion does not support a tensed theory of time, which requires a preferred foliation. It is argued that the only reliable inference from the EPR example and the use of entropic clocks is an inference not just to a Leibnizian order of the succession of events but a frame-invariant order according to some selected clocks.

This article investigates the relationship between Hume’s causal philosophy and Newton ’s philosophy of nature. I claim that Newton ’s experimentalist methodology in gravity research is an important background for understanding Hume’s conception of causality: Hume sees the relation of cause and effect as not being founded on a priori reasoning, similar to the way that Newton criticized non - empirical hypotheses about the properties of gravity. However, according to Hume’s criteria of causal inference, the law of universal gravitation is (...) not a complete causal law, since it does not include a reference either to contiguity or to temporal priority. It is still argued that because of the empirical success of Newton ’s theory—the law is a statement of an exceptionless repetition—Hume gives his support to it in interpreting gravity force instrumentally as if it bore a causal relation to motion.

On a standard interpretation, Hume argued that reason is not practical, because its operations are limited to “demonstration” and “probability.” But recent critics claim that by limiting reason’s operations to only these two, his argument begs the question. Despite this, a better argument for motivational skepticism can be found in Hume’s text, one that emphasizes reason’s inability to generate motive force against contrary desires or passions. Nothing can oppose an impulse but a contrary impulse, Hume believed, and reason cannot generate (...) an impulse. This better argument is here developed and defended. Two lines of objection to it can be anticipated: that reason actually can generate impulsive force, based on contents of its normative judgments and that reason neither can nor needs to generate an impulse, since the actions of rational agents are not determined by forceful impulses of desire, as Hume supposed. These objections are answered by pointing out their unsatisfying consequences. (shrink)

This paper will make the case that we can find in Kant’s Second Analogy a substantive response to Hume’s argument on induction. This response is substantive insofar as it does not merely consist in independently arguing for the opposite conclusion, but rather, it identifies and exploits a gap in this argument. More specifically, Hume misses the possibility of justifying the uniformity of nature as a synthetic a priori proposition, which Kant looks to establish in the Second Analogy. Note that the (...) focus on the paper is on Kant’s identification of the form that a solution to Hume’s inductive scepticism must take. In making this point, my paper will look to establish two lemmas: Kant identifies synthetic a priori judgments as a means of justifying metaphysical knowledge in a way that circumvents Hume’s dichotomy between matters of fact and relations of ideas; the Second Analogy looks to establish the uniformity of nature of as a synthetic a priori proposition. However, my paper generally abstains from the question of the tenability of Kant’s argument in the Second Analogy. Doing justice to this latter discussion would require more space than I am able to offer here. My paper therefore has a conditional bearing on the philosophical issue of inductive scepticism. If one believes Kant’s Second Analogy to be philosophically cogent, then Kant offers a successful justification of induction against Hume’s scepticism. If not, then at least one can still admire Kant’s identification of the gap in Hume’s argument, which, to a degree, can be exploited independently of Kant’s system. (shrink)

In the literature seeking to explain concepts in terms of their point, talk of ‘the point’ of concepts remains under-theorised. I propose a typology of points which distinguishes practical, evaluative, animating, and inferential points. This allows us to resolve tensions such as that between the ambition of explanations in terms of the points of concepts to be informative and the claim that mastering concepts requires grasping their point; and it allows us to exploit connections between types of points to understand (...) why they come apart, and whether they do so for problematic ideological reasons or for benignly functional reasons.

From David Hume onwards, many philosophers have argued that moral thinking is characterized by a tendency to “project” our own mental states onto the world. This metaphor of projection may be understood as involving two empirical claims: the claim that humans experience morality as a realm of objective facts (the experiential hypothesis), and the claim that this moral experience is immediately caused by affective attitudes (the causal hypothesis). Elsewhere I argued in detail against one form of the experiential hypothesis. My (...) main aim in this paper is to show that, considering recent psychological studies about folk metaethics and the relation between moral judgements and emotions, the causal hypothesis must be considered problematic too. First, the most common argument in favor of the causal hypothesis is based on an implausible premise and a dubious assumption. Second, ordinary people’s moral experience is influenced by a non-affective factor, namely their openness to divergent moral views. And third, projectivism in general and its causal hypothesis in particular might not even hold true for affective moral judgements. This negative assessment of projectivism is significant both for our understanding of moral cognition as an empirical phenomenon and for metaethics. (shrink)

Resumen La filosofía de Hume se ha interpretado tradicionalmente como radicalmente escéptica respecto de la posibilidad de otorgarle justificación epistémica a nuestras creencias inductivas acerca del futuro y lo inobservado.

In Treatise 2.3.4.5 Hume provides an explanation of why ‘we naturally desire what is forbid, and take a pleasure in performing actions, merely because they are unlawful’. Hume's explanation of this phenomenon has barely received any attention so far. But a detailed analysis bears fruit for both Humean scholarship and contemporary moral psychology. After putting the passage in its context, I explain why desiring and taking pleasure in performing certain actions merely because they are unlawful poses a challenge to Hume's (...) theory of evaluation. Then I propose a solution of the challenge which draws on Hume's treatment of malice, and highlights the role played by comparison and the self in these apparently paradoxical passions. Finally, I distinguish three views in contemporary discussions of desiring something under the guise of the bad (negationism, parasitism, at-face-valuism), and I argue that Hume's account stands out as a particularly plausible version of the third view.

This paper considers and argues against old and recent readings of Hume according to which his account of moral judgement is non-cognitivist. In previous discussions of this topic, crucial metaethical distinctions-between sentimentalism and non-cognitivism and between psychological and semantic non-cognitivism-are often blurred. The paper aims to remedy this and argues that making the appropriate metaethical distinctions undermines alleged support for non-cognitivist interpretations of Hume. The paper focuses in particular on Hume's so-called 'motivation argument' and argues that it is a poor (...) basis for non-cognitivist interpretations. While there is textual support for attributing to Hume what may be called 'modally weak' motivational internalism, there is no solid textual support for attributing to him either psychological or semantic non-cognitivism. The paper also challenges briefly some further alleged support for non-cognitivist interpretations. It concludes by offering some positive evidence against such interpretations, namely that Hume appears to hold that there are moral beliefs and moral knowledge. (shrink)

A characteristically Humean pattern of explanation starts by claiming that we have a certain kind of feeling in response to some objects and then takes our having such feelings to provide an explanation of how we come to think of those objects as having some feature that we would not otherwise be able to think of them as having. This core pattern of explanation is what leads Simon Blackburn to dub Hume ‘the first great projectivist.’ This paper critically examines the (...) philosophical and textual basis for interpreting Hume as a causal projectivist. I argue that projectivist interpretations of Hume's account of causation are motivated by two convictions: that beliefs about causation, according to Hume, are not just beliefs about regularity relations and that believing that two events are necessarily connected, according to Hume, is not merely having a belief about something that occurs in one's mind. I suggest that the latter conviction is worth revisiting, both for textual and philosophical reasons. (shrink)

This paper discusses some key connections between Berkeley's reflections on language in the introduction to his Treatise on the Principles of Human Knowledge and the doctrines espoused in the body of that work, in particular his views on vulgar causal discourse and his response to the objection that his metaphysics imputes massive error to ordinary thought. I argue also that there is some mileage in the view that Berkeley's thought might be an early form of non-cognitivism.

This paper discusses the role of Hume’s “Natural History of Religion” (NHR) in his campaign against the rational acceptability of religious belief by discussing and rebutting some objections have been lodged to my previous presentations of my reading of the NHR. In earlier work I argued that the causal account of religious belief offered therein, if accepted as the best account, rationally destabilizes that belief. By this, I mean that acknowledging that the account is the best of the belief provides (...) a reason to suspend the belief unless and until some further epistemic justification is given for that belief. As such, the account leaves those who think that the belief can be given some epistemic justification unmoved, but has a particular force against the fideist who holds that justification is not required. In this paper I show in more detail than in previous work its relevance to a particular form of fideism, and rebut objections to my reading offered by Jennifer Marušic. (shrink)

David Hume’s and later Ludwig Wittgenstein’s views on concepts are generally presented as standing in stark opposition to each other. In a nutshell, Hume’s theory of concepts is taken to be subjectivistic and atomistic, while Wittgenstein is metonymic with a broadly pragmatistic and holistic doctrine that gained much attention during the second half of the 20th century. In this essay, I shall argue, however, that Hume’s theory of concepts is indeed much more akin to the views of Wittgenstein and his (...) epigones than many, including Wittgenstein himself, probably might have suspected. As I try to show, Hume anticipates many themes central to Wittgenstein’s writings on language and meaning, and actually takes initial steps towards both an anti-subjectivistic and anti-atomistic psychology and epistemology.

Hume regards the ‘absolute’ necessity attending demonstrable propositions as an expression of the limitations of human imagination. When we register our modal commitments in ordinary descriptive language, affirming that there are such-and-such absolute necessities, possibilities, and impossibilities, we are projecting our sense of what the human mind can and cannot conceive. In some ways the account parallels Hume’s famous treatment of the necessity of causes, and in some respects it anticipates recent expressivist theories of absolute modality. I marshal the evidence (...) for this interpretation, show how it can explain a number of otherwise puzzling features of Hume’s modal epistemology and metaphysics, and situate this account of our modal discourse in Hume’s wider programme for a science of human nature. (shrink)

In this paper, I argue that there is a sceptical argument against the senses advanced by Hume that forms a decisive objection to the Metaphysically Realist interpretations of his philosophy – such as the different naturalist and New Humean readings. Hume presents this argument, apparently starting with the primary/secondary qualities distinction, both in A Treatise of Human Nature, Book 1, Part 4, Section 4 (Of the modern philosophy) (1739) and An Enquiry concerning Human Understanding, Section 12 (Of the Academical or (...) Sceptical Philosophy), paragraphs 15 to 16 (1748). The argument concludes with the contradiction between consistent reasoning (causal, in particular) and believing in the existence of Real (distinct and continued) entities. The problem with the Realist readings of Hume is that they attribute both to Hume. So their Hume is a self-reflectively inconsistent philosopher. I show that the various ways to avoid this problem do not work. Accordingly, this paper suggests a non-Realist interpretation of Hume's philosophy: Hume the philosopher suspends his judgment on Metaphysical Realism. As such, his philosophical attitude is neutral on the divide between materialism and idealism. (shrink)

When making moral judgments, people are typically guided by a plurality of moral rules. These rules owe their existence to human emotions but are not simply equivalent to those emotions. And people’s moral judgments ought to be guided by a plurality of emotion-based rules. The view just stated combines three positions on moral judgment: [1] moral sentimentalism, which holds that sentiments play an essential role in moral judgment,1 [2] descriptive moral pluralism, which holds that commonsense moral judgment is guided by (...) a plurality of moral rules2, and [3] prescriptive moral pluralism, which holds that moral judgment ought to be guided by a plurality of moral rules. In what follows, we will argue for all three positions. We will not present a comprehensive case for these positions nor address many of the arguments philosophers have developed against them. What we will try to show is that recent psychological work supports sentimentalist pluralism in both its descriptive and prescriptive forms. (shrink)

How is it that, as fiction readers, we are nonplussed by J. K. Rowling's prescription to imagine Ronan, Bane, and Magorian, three different centaurs of the Forbidden Forrest at Hogwarts? It is usually held in the philosophical literature on fictional discourse that singular imaginings of fictional objects are impossible, given the blatant nonexistence of such objects. In this paper, I have a dual purpose: on the one hand, to show that, without being committed to Meinongeanism, we can explain the phenomenon (...) of singular imaginings of different nonexistents of the same kind; while, at the same time, to attribute this position to Thomas Reid, thus correcting some misunderstandings of his view on imagination.

In the “Appendix” to the Treatise, Hume claims that he has discovered a “very considerable” mistake in his earlier discussion of the self. Hume's expression of the problem is notoriously opaque, leading to a vast scholarly debate as to exactly what problem he identified in his earlier account of the self. I propose a new solution to this interpretive puzzle. I argue that a tension generated by Hume's conceptual skepticism about real “principles of union” and his account of fictions of (...) the imagination is the defect identified in the “Appendix.”. (shrink)

Hume’s claim that we project necessity onto objects we take to be causally related has been influential in contemporary discussions of modality, inspiring deflationary accounts of our modal commitments. Hume is commonly understood as holding that modal projection explains our judging that an effect must follow its cause. This misunderstands the role of projection in Hume’s discussions of causation and causal judgement. Projection is a diagnosis of a distinctively philosophical confusion: the commitment to mind-independent necessary connections. In arguing for this, (...) I provide an account of the psychological process that, in Hume’s view, underlies projection. This account resolves problems with Hume’s projectivism identified by his commentators. (shrink)

Traditionally one main emphasis of the quantum mechanical measurement theory is on the question how the pure state of the compound system 'measured system + measuring apparatus' is transformed into the 'mixture' of all possible results of that measurement, weighted with their probability: the so-called “disappearance of the interference terms”. It is argued in this note that in reality there is no such transformation, so that there is no need to account for such a transformation theoretically. _German_ Gewöhnlich liegt ein (...) Hauptgewicht der quantenmechanischen Messtheorie auf der Frage des Übergangs vom,reinen Fall' des Gesamtsystems,gemessenes System + Messgerät' in das,Gemenge' aus allen möglichen Messergebnissen, gewichtet mit ihren Wahrscheinlichkeiten: Das sog.,,Verschwinden der Interferenzterme“.

This essay examines the manner in which Hume challenges the cognitivist and realist intuitions informing our ordinary experience of value by identifying values with mind-dependent feelings and by separating facts from values. However, through a process of interpretive rehearsal of Hume’s arguments in the first two parts of the paper we find that they come under increasing internal strain, which points, contrary to his initial argument about the irreducibly phenomenal aspects of value experience, to the motivational role of reason and (...) to the identification of values, not with mind-dependent feelings, but with dispositional properties of objects. The third and final part of the paper will offer a systematic reconstruction of his arguments with a view to suggesting one possible – descriptivist – alternative to Hume’s initial challenges, which can serve to satisfy the emerging cognitivist and realist needs of his arguments.

I outline Hume’s views about conceivability evidence. Then I critically scrutinise two threats to conceivability-based modal epistemology. Both arise from Hume’s criticism of claims to knowing necessary causal relationships: Firstly, a sceptical stance towards causal necessity may carry over to necessity claims in general. Secondly, since – according to a sceptical realist reading – Hume grants the eventuality of causal powers grounded in essential features of objects, conceivability-based claims to comprehensive metaphysical possibilities seem endangered. I argue that although normal conceivability-based (...) claims are defeasible, they are prima facie vindicated. Humes Ansichten über Vorstellbarkeit als Indikator für Möglichkeit werden zusammengefasst. Dann werden zwei Schwierigkeiten für eine auf Vorstellbarkeit basierende modale Erkenntnistheorie aufgeworfen. Beide entstehen aus Humes Kritik an Ansprüchen aufWissen notwendiger kausaler Beziehungen. Erstens könnte sich eine skeptische Haltung gegenüber kausaler Notwendigkeit auf Ansprüche, notwendige Zusammenhänge zu kennen, im allgemeinen auswirken. Zweitens gesteht Hume gemäß einem skeptischen Realismus die Eventualität kausaler Kräfte zu, die in wesentlichen Eigenschaften der Dinge gründen. Dies scheint unvereinbar mit der auf Vorstellbarkeit gestützten Behauptung umfassender metaphysischer Möglichkeiten. Dagegen soll gezeigt werden, dass auf Vorstellbarkeit gestützte modale Wissensansprüche zwar widerlegbar, aber prima facie gerechtfertigt sind. (shrink)

Hume was a cognitive scientist of religion avant la lettre. His Natural History of Religion (1757 [2007]) locates the origins of religion in human nature. This paper explores similarities between some of his ideas and the cognitive science of religion, the multidisciplinary study of the psychological origins of religious beliefs. It also considers Hume’s distinction between two questions about religion: its foundation in reason (the domain of natural theology and philosophy of religion) and its origin in human nature (the domain (...) of cognitive science of religion).

In his brief treatment of memory, Hume characterizes memory using two kinds of criteria: ideas’ phenomenal character and their correspondence to the past experiences from which they derived. These criteria have seemed so perplexing to interpreters, both individually and jointly, that Hume’s account of memory is commonly considered one of the weakest parts of his philosophical system. This paper defends Hume’s criteria by showing that they achieve two theoretical aims: a scientific classification of ideas and a definition of ‘memory.’ In (...) particular, I argue that Hume’s definition of ‘memory’ is cogent in light of Putnamian considerations about definitions.

This essay gives a new interpretation of Hume's second thoughts about minds in the Appendix, based on a new interpretation of his view of composition. In Book 1 of the Treatise, Hume argued that, as far as we can conceive it, a mind is a whole composed by all its perceptions. But—this essay argues—he also held that several perceptions form a whole only if the mind to which they belong supplies a “connexion” among them. In order to do so, it (...) must contain a further perception or perceptions. But when the perceptions in question are all of those belonging to a given mind—as in the section “Of personal identity” and the Appendix—there cannot be a further perception in that mind, and so those perceptions do not form a whole. Hence, Hume's views were inconsistent. This essay argues that, unlike most others, this interpretation explains his retreat to skepticism in the Appendix. (shrink)

The past two decades have seen an explosion of literature on Hume's views about mental representation and intentionality. This essay gives a roadmap of this literature, while arguing for two main interpretive claims. First, Hume aims to naturalize all forms of mental representation and intentionality, that is, to explain them in terms of properties and relations that are found throughout the natural world (not just in minds) and that are not, individually, peculiar to representational or intentional things. Second, Hume holds (...) that the passions are not representational but do have intentionality extrinsically. (shrink)

Hsueh M. Qu has recently argued that Hume's famed "Separability Principle" from the Treatise entangles him in a contradiction. Qu offers a modified principle as a solution but also argues that the mature Hume would not have needed to avail himself of it, given that Hume's arguments in the first Enquiry do not depend on this principle in any form. To the contrary, I show that arguments in the first Enquiry depend on this principle, but I agree with Qu that (...) Qu's solution to Hume's quandary frees him of the contradiction. Next, I compare Qu's solution to Hume's original position. By analyzing the divergent forms of Hume's "Dictum" that follow from them, I show that Qu's solution and Hume's original position have significantly different consequences in a range of domains, including Hume's modality. Generally, Qu's solution fits better with Hume's other commitments—even though Hume often fails to recognize it—thereby increasing its plausibility. (shrink)

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.

Hume is known for his claim that our idea of causation is nothing beyond constant conjunction, and that our idea of necessary connection is nothing beyond a felt determination of the mind. In short, Hume endorses a "thin" conception of causation and necessary connection. In recent years, however, a sizeable number of philosophers have come to view Hume as someone who believes in the existence of thick causal connections - that is, causal connections that allow one to infer a priori (...) the effect from the cause, and vice versa. Hume doesn't wish to deny such connections, said philosopher's claim, he only seeks to demonstrate that we can't know anything about the nature of the thick causal connections that make up the natural world. In this dissertation, I defend the old or traditional interpretation of Hume on causation. I draw attention to the important but neglected role of clear and distinct perception in Hume's thought, arguing that for Hume our impressions are clear and distinct perceptions, whereas our ideas are faint and obscure. Accordingly, Hume's copy principle - the thesis that our ideas are copies of our impressions - is Hume's way of rendering our naturally obscure and confused ideas distinct. One need only discern the impression from which said ideas are copied. In this way, I show that Hume's opinion concerning our idea of thick causation is that it's an obscure and confused idea, and that the only clear and distinct idea we can have of causation is thin causation. Furthermore, since meaning for Hume is a matter of a word's being associated with an idea, Hume thinks that an expression such as "thick causation" is meaningless or confused. In one sense, then, Hume is a positivist, and as such doesn't believe in thick causal connections. (shrink)

The following inquiry pursues two interlinked aims. The first is to understand Wittgenstein's idea of non-foundational certainty in the context of a reading of On Certainty that emphasizes its Pyrrhonian elements. The second is to read Wittgenstein's remarks on idealism/radical skepticism in On Certainty in parallel with the discussion of rule-following in Philosophical Investigations in order to demonstrate an underlying similarity of philosophical concerns and methods. I argue that for the later Wittgenstein, what is held certain in a given context (...) of inquiry or action is a locally transcendental condition of the inquiry or action in question. In On Certainty, Wittgenstein's analysis of the difference between knowledge and certainty forms the basis of his critique of both Moore's "Proof" and radical skepticism. This critique takes the shape of rejection of a presupposition shared by both parties, and utilizes what I identify as a Pyrrhonian-style argument against opposed dogmatic views. Wittgenstein's method in this text involves describing epistemic language-games. I demonstrate that this is consistent with the rejection of epistemological theorizing, arguing that a Wittgensteinian "picture" is not a theory, but an impressionistic description that accomplishes two things: (i) throwing into relief problems with dogmatic theories and their presuppositions, and (ii) describing the provenance of linguistic and epistemic practices in terms of norms grounded in convention. Convention, in turn, is not arbitrary, but grounded in the biological and social natures of human beings--in what Wittgenstein calls forms of life. Thus there is a kind of naturalism in the work of the later Wittgenstein. It is a naturalism that comes neatly dovetailed with Pyrrhonism--a combination of strategies traceable to Hume's work in the Treatise. I read Hume as someone who develops the Pyrrhonian method to include philosophy done "in a careless manner," and argue that Wittgenstein adopts a similar method in his later works. Finally, I explain the deference to convention in the work of both Hume and Wittgenstein by reference to a passage in Sextus' Outlines, on which I provide a gloss in the final chapter of this work.

The Title Principle is seen by a number of commentators as crucial to Hume’s resolution of skeptical doubts in THN 1.4.7, thus providing an answer to Kemp Smith’s (1941) famous worry regarding the tension between Hume’s skepticism and his naturalism. However, I will argue that in the Enquiry, Hume rejects both the Title Principle and the role of the passions in his epistemology. Those who think that neither the Title Principle nor the passions play a significant role in THN 1.4.7 (...) will likely take this as grist for their mills. But for those who endorse such interpretations, my argument presents an interpretive burden to provide some explanation as to why Hume might have become dissatisfied with this epistemic framework, abandoning it in his later work. Having raised this interpretive burden, my paper also seeks to bear it by providing such an explanation. (shrink)

The subject of this essay-based dissertation is Hume’s natural philosophy. The dissertation consists of four separate essays and an introduction. These essays do not only treat Hume’s views on the topic of natural philosophy, but his views are placed into a broader context of history of philosophy and science, physics in particular. The introductory section outlines the historical context, shows how the individual essays are connected, expounds what kind of research methodology has been used, and encapsulates the research contributions of (...) the essays. The first essay treats Newton’s experimentalist methodology in gravity research and its relation to Hume’s causal philosophy. It is argued that Hume does not see the relation of cause and effect as being founded on a priori reasoning, similar to the way in which Newton criticized non-empirical hypotheses about the causal properties of gravity. Contrary to Hume’s rules of causation, the universal law does not include a reference either to contiguity or succession, but Hume accepts it in interpreting the force and the law of gravity instrumentally. The second article considers Newtonian and non-Newtonian elements in Hume more broadly. He is sympathetic to many prominently Newtonian themes in natural philosophy, such as experimentalism, critique of hypotheses, inductive proof, and the critique of Leibnizian principles of sufficient reason and intelligibility. However, Hume is not a Newtonian philosopher in many respects: his conceptions regarding space and time, the vacuum, the specifics of causation, the status of mechanism, and the reality of forces differ markedly from Newton’s related conceptions. The third article focuses on Hume’s Fork and the proper epistemic status of propositions of mixed mathematics. It is shown that the epistemic status of propositions of mixed mathematics, such as those concerning laws of nature, is that of matters of fact. The reason for this is that the propositions of mixed mathematics are dependent on the Uniformity Principle. The fourth article analyzes Einstein’s acknowledgement of Hume regarding special relativity. The views of the scientist and the philosopher are juxtaposed, and it is argued that there are two common points to be found in their writings, namely an empiricist theory of ideas and concepts and a relationist ontology regarding space and time.

This thesis investigates Hume’s philosophy of external existence in relation to, and within the context of, his philosophy of scepticism. In his two main works on metaphysics – A Treatise of Human Nature (1739–40) and the first Enquiry (first ed. 1748) – Hume encounters a predicament pertaining to the unreflective, ‘vulgar’ attribution of external existence to mental perceptions and the ‘philosophical’ distinction between perceptions and objects. I argue that we should understand this predicament as follows: the vulgar opinion is our (...) natural and default belief for Hume, but causal reasoning reveals it to be false, and the philosophical alternative is a confabulation that we cannot permanently believe and is devoid of justification. Hume uses the fact that we cannot have a satisfactory account of belief in external existence as a sceptical consideration to motivate his wider philosophical scepticism. Hume’s response to his predicament about external existence is found in the context of his confrontation with other sceptical worries (Treatise 1.4.7 and Enquiry 12), in which Hume also reflects generally on the nature and implications of scepticism. I argue that we should characterise Hume’s position as residually sceptical. This means that, while Hume accepts the unanswerability of some sceptical problems, he denies that it is possible to eradicate all belief as a result (and denies that it is practically useful to even try) and instead uses sceptical problems as a motivation to adopt a moderately sceptical position. While we inevitably return to entertaining the vulgar belief, there is no solution to the sceptical predicament; Hume does not endorse the vulgar belief, or the philosophical system, or indeed any alternative system of the external world that might extinguish the predicament. Sceptical doubt, for Hume, does not derail intellectual pursuits, but rather modifies our attitudes in those very pursuits. (shrink)

In this paper, I argue that Hume has an insight into the heart of most of “new philosophy” when he claims that according to it, proper sensibles are not Real properties of material substance and Real bodies. I call this tenet “the Proper Sensibles Principle” (PSP). In the second part of the paper, I defend the interpretation - mainly against Don Garrett’s doubts - that the PSP is a rational tenet in Hume’s view and he thus endorses it. Its rationality (...) means that the PSP has a firm foundation in inductive-causal reasoning. (shrink)

The aim of this work is to demarcate, develop, and defend the commitments and consequences of metaethical minimalism. Very roughly, this is the position that a commitment to objective moral truths does not require any accompanying ontological commitments. While there are few, if any, who call themselves “metaethical minimalists”, I endeavor to uncover existing articulations of metaethical minimalism which have been presented under different names, attempting to identify the common ground between them. As I interpret the position, all metaethical minimalists (...) are committed to the same positive pair of claims (what I call the Objectivity Thesis): “a) Moral truths are strongly mind-independent; b) there are moral truths.” Taken by itself, however, this pair of claims is not sufficient for differentiating their view from the moral realist’s. Consequently, the minimalist must also articulate that which they are denying about the non-minimalist approach, or what I call the “negative ontological thesis”. I offer my own version of this negative thesis and argue for its dialectical advantages. -/- In Chapters 3 and 4, I focus my attention on attacks on the viability of metaethical minimalism in the form of two “challenges” that aim to problematize a commitment to objective moral truths absent any accompanying ontological commitment. The big-picture takeaway from these chapters is that minimalism can defend itself by playing to the dialectical advantage I find for it in Chapter 2 as well as by being creative about minimalist constructions/reworkings of plausible principles/lines of reasoning that seem to contradict it. -/- The temptation to embrace quietism is strong among minimalists, but in Chapters 5, 6, and 7 I aim to show that there is a positive alternative available for the minimalist interested in developing a full picture of their position. Chapter 5 is aimed at providing an adequate understanding of the distinction between the objects of purely normative thoughts and objects of thoughts about reality. Building on this are Chapters 6 and 7, which argue in favor of an account of the relationship between emotion and evaluative knowledge that is consistent with metaethical minimalism. (shrink)
