Since the mid-1970s, scholars have recognized that the skeptical interpretation of Hume's central argument about induction is problematic. The science of human nature presupposes that inductive inference is justified and there are endorsements of induction throughout "Treatise" Book I. The recent suggestion that I.iii.6 is confined to the psychology of inductive inference cannot account for the epistemic flavor of its claims that neither a genuine demonstration nor a non-question-begging inductive argument can establish the uniformity principle. For Hume, that inductive inference (...) is justified is part of the data to be explained. Bad argument is therefore excluded as the cause of inductive inference; and there is no good argument to cause it. Does this reinstate the problem of induction, undermining Hume's own assumption that induction is justified? It does so only if justification must derive from "reason", from the availability of a cogent argument. Hume rejects this internalist thesis; induction's favorable epistemic status derives from features of custom, the mechanism that generates inductive beliefs. Hume is attracted to this externalist posture because it provides a direct explanation of the epistemic achievements of children and non-human animals — creatures that must rely on custom unsupplemented by argument.

Recent work on Mary Shepherd has largely focused on her metaphysics, especially as a response to Berkeley and Hume. However, relatively little attention has thus far been paid to the epistemological aspects of Shepherd’s program. What little attention Shepherd’s epistemology has received has tended to cast her as providing an unsatisfactory response to the skeptical challenge issued by Hume. For example, Walter Ott and Jeremy Fantl have each suggested that Shepherd cannot avoid Hume’s inductive skepticism even if she is granted (...) her metaphysics. In this paper, I examine Shepherd’s epistemology and argue that her response to Hume is more successful than the current literature suggests. In particular, I argue that, if Shepherd is granted her metaphysics, she can answer Hume’s demand for a rational justification of ordinary inductive inferences via a deductively justified uniformity principle and an appeal to parsimony.

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.

This paper supports the contention that the general rules introduced by Hume in the Treatise on Human Nature (THN 1.3.15) are a selection mechanism for inductive inferences, which rejects two sources of inefficiency : (i) from emotional origin, which would reduce the uneasiness coming from a possible failure in the uniformity of nature ; (ii) from cognitive origin, which would tolerate the possible overflow of the imagination on judgment. A growing consensus in recent decades, which distinguishes between two kinds of (...) rules — extensive and corrective — is at the basis of this device. Whereas the extensive rules allow us to go beyond a singular experience and derive a wider range of inferences, the corrective rules, whose command opposes the philosopher to the vulgar, control and rectify the effects of extensive rules alone, so as to eliminate emotional and cognitive inefficiencies, and to make inferences that, borrowing the expression to Peirce, we will designate as abductive.

A common criticism of Hume’s famous anti-induction argument is that it is vitiated because it fails to foreclose the possibility of an authentically probabilistic justification of induction. I argue that this claim is false, and that on the contrary, the probability calculus itself, in the form of an elementary consequence that I call Hume’s Theorem, fully endorses Hume’s argument. Various objections, including the often-made claim that Hume is defeated by de Finetti’s exchangeability results, are considered and rejected.

This paper explores early Australasian philosophy in some detail. Two approaches have dominated Western philosophy in Australia: idealism and materialism. Idealism was prevalent between the 1880s and the 1930s, but dissipated thereafter. Idealism in Australia often reflected Kantian themes, but it also reflected the revival of interest in Hegel through the work of ‘absolute idealists’ such as T. H. Green, F. H. Bradley, and Henry Jones. A number of the early New Zealand philosophers were also educated in the idealist tradition (...) and were influential in their communities, but produced relatively little. In Australia, materialism gained prominence through the work of John Anderson, who arrived in Australia in 1927, and continues to be influential. John Anderson had been a student of Henry Jones, who might therefore be said to have influenced both main strands of Australian philosophical thought. (shrink)

David Hume has traditionally been regarded as a skeptic, perhaps the most formidable in the history of Western philosophy. Since the publication of Norman Kemp Smith's Philosophy of David Hume in 1941, however, there has been an increasing tendency to downplay the skeptical dimension of Hume's philosophy, in some cases to the point of denying that Hume is a serious skeptic, or even a skeptic at all. Much of the motivation for a nonskeptical reading of Hume comes from recognition of (...) his endorsement of empirical science and his own project of founding a "science of man." Recent scholarship has, in my opinion correctly, recognized Hume as a constructive rather than a purely destructive thinker. Yet this recognition has, in my opinion incorrectly, gone hand in hand with a tendency to overlook or deny the skeptical side of Hume's thought. In this work, I address the issue of Hume's skepticism. I believe that though the issue of Hume's skepticism is more complicated than is suggested by some of those who interpret him as a skeptic, nevertheless the traditional view is more true to Hume's texts than is a nonskeptical interpretation. I argue, on the basis of a reading of the Treatise of Human Nature and Enquiry Concerning Human Understanding, that Hume is a serious theoretical skeptic with regard to much of our alleged knowledge. In saying that Hume is a serious theoretical skeptic I mean that Hume's skeptical pronouncements are in general sincere, not ironic, Hume's skepticism extends to a large part of our alleged knowledge, and Hume's skepticism is a result of his substantive philosophical views. In saying that Hume is a serious theoretical skeptic I mean that though Hume doesn't prescribe eschewal of beliefs that are not rationally justified, he thinks that much of our alleged knowledge essentially involves beliefs that cannot be rationally justified and that hence much of our alleged knowledge is not knowledge at all.
