In the conclusion to the first book of the Treatise, Hume's skeptical reflections have plunged him into melancholy. He then proceeds through a complex series of stages, resulting in renewed interest in philosophy. Interpreters have struggled to explain the connection between the stages. I argue that Hume's repeated invocation of the four humors of ancient and medieval medicine explains the succession, and sheds a new light on the significance of skepticism. The humoral context not only reveals that Hume conceives of (...) skepticism primarily as a temperament, not a philosophical view or system. It also resolves a puzzle about how Hume can view skepticism as both an illness and a cure. The skeptical temperament can, depending on its degree of predominance, either contribute to or upset the balance of temperaments required for proper mental functioning. (shrink)

In A Treatise of Human Nature, David Hume presents an argument according to which all knowledge reduces to probability, and all probability reduces to nothing. Many have criticized this argument, while others find nothing wrong with it. In this paper we explain that the argument is invalid as it stands, but for different reasons than have been hitherto acknowledged. Once the argument is repaired, it becomes clear that there is indeed something that reduces to nothing, but it is something other (...) than what, according to many, Hume had in mind. Thus two views emerge of what exactly it is that reduces. We surmise that Hume failed to distinguish the two, because he lacked the formal means to differentiate between a rendering of his argument that is in accordance with the probability calculus, and one that is not.

in the treatise, hume claims to identify many “fictions of the imagination” among both “vulgar” and philosophical beliefs. To name just a few, these include the fiction of one aggregate composed of many parts,1 the fiction of a material object’s identity through change, and the fiction of a human mind’s identity through change and interruption in its existence. Hume claims that these fictions and others like them are somehow defective: in his words, they are “improper,” “inexact,” or not “strict”. I (...) will argue that this claim conflicts with other commitments.. (shrink)

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)

A standard interpretation of Hume’s naturalism is that it paved the way for a scientistic and ‘disenchanted’ conception of the world. My aim in this paper is to show that this is a restrictive reading of Hume, and it obscures a different and profitable interpretation of what Humean naturalism amounts to. The standard interpretation implies that Hume’s ‘science of human nature’ was a reductive investigation into our psychology. But, as Hume explains, the subject matter of this science is not restricted (...) to introspectively accessible mental content and incorporates our social nature and interpersonal experience. Illuminating the science of human nature has implications for how we understand what Hume means by ‘experience’ and thus how we understand the context of his epistemological investigations. I examine these in turn and argue overall that Hume’s naturalism and his science of man do not simply anticipate a disenchanted conception of the world. (shrink)

John Rawls shows a deep influence of David Hume’s thought, mainly at his Theory of Justice, though also at the rest of his works. This influence is well-known in the field of political philosophy, much less in the field of moral philosophy. Rawls reads Hume’s thought with a sceptic and naturalistic key, attributing him what he calls a “nature fideism”. Besides this, attributes to Hume an ethical and political position linked with the classical utilitarianism. Nevertheless, his skeptical epistemology will move (...) away, paradoxically, to Hume from the utilitarian positions. Hume’s ethics and politics will finish, according to Rawls, showing a purely descriptive character and a lack of normative purposes. Hume does not have in the strict sense a theory of practical reason. This article examines and puts in question this interpretation of Hume proposed by John Rawls. The philosophy of Hume is not aporetically skeptical, articulates the moral roles of reason and the passions; and finally, is not only connected with utilitarianism; his defense of the role of utility frees to his theory of some of the main contradictions of classical utilitarianism. Besides this, the theory of the “judicious spectator” can be considered a form of a theory of practical rationality. (shrink)

Cet article montre qu'il est faux de considérer le scepticisme mitigé que présente Hume dans la section 12 de l' Enquête sur l'entendement humain comme un scepticisme modéré. Afin d'établir ce point, l'argument principal est qu'il existe un rapport de causalité par lequel l'affect que laissent derrière eux les doutes pyrrhoniens est en grande partie responsable de la production du scepticisme mitigé. Cet affect n'est pas la mélancolie paralysante dont parle le Traité de la nature humaine , mais ce qui (...) motive le sceptique à être prudent parce qu'il est sensible à la fragilité des facultés qu'il a radicalement éprouvée dans l'exercice des doutes outrés. Le scepticisme mitigé n'est pas un oubli, mais, au contraire, une mémoire du scepticisme excessif. (shrink)

Hume’s account of contrariety in Book I of the Treatise poses several interpretive puzzles. I consider each in turn and offer a novel interpretation of contrariety based on Hume’s discussion of the passions. That Book II and Book I form a complete chain of reasoning suggests that the way in which passions are related is analogous to the way in which ideas are related in the understanding. I argue that Hume identifies three species of empirical contrariety in Book II: contraries, (...) oppositions, and contradictions. All three species help clarify Hume’s remarks concerning contrariety in Book I. I further identify a second genus I call logical contrariety by drawing on Hume’s discussion of fictitious duration and distance. (shrink)

This is a reply to Donald Ainslie's discussion of Terence Penelhum's work on Hume, Locke and the nature of consciousness; although agree on many points about the differences between Locke and Hume, I take issue with Ainslie's views about the epistemic status Hume accords to introspective acts.
