Sir William Drummond (1770?-1828) enjoyed considerable notoriety in the early nineteenth century as the author of the Academical Questions (1805), a manifesto for immaterialism that is at the same time a creative synthesis of ancient and modern forms of scepticism. In this paper I advance an interpretation of Drummond's work that emphasises his extensive employment and adaptation of Hume's own ‘Academical or Sceptical Philosophy’. I also document the impact of the Academical Questions on the contemporary philosophical scene, including its decisive (...) influence on Shelley's philosophical development. (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)

In this article, a novel interpretation of one of the problems of Hume scholarship is defended: his view of Metaphysical Realism or the belief in an external world (that there are ontologically and causally perception-independent, absolutely external and continued, i.e. Real entities). According to this interpretation, Hume's attitude in the domain of philosophy should be distinguished from his view in the domain of everyday life: Hume the philosopher suspends his judgement on Realism, whereas Hume the common man firmly believes in (...) the existence of Real entities. The defended reading is thus a sceptical and Realist interpretation of Hume. As such, it belongs to the class of what can be called no-single-Hume interpretations (Richard H. Popkin, Robert J. Fogelin, Donald L. M. Baxter), by contrast to single-Hume readings, which include Realist (naturalist, New Humean) and the traditional Reid-Green interpretation (i.e. Hume believes that there are no Real entities). Hume's distinction between the domains of philosophy and everyday life, which is argued to be epistemological, is employed in order to reconcile his scepticism with his naturalism and constructive science of human nature. The article pays special attention to the too much neglected second profound argument against the senses in Part 1, Section 12 of Hume's first Enquiry and the corresponding argument in Section 4, Part 4, Book 1 of the Treatise.

I argue in this paper that, like the Pyrrhonism of Sextus Empiricus, Wittgenstein’s response to negative–dogmatic skepticism in On Certainty turns on the attempt to free us from the demands of traditional philosophy and is therefore not a philosophical position, strictly speaking. Rather, it is a therapeutic metaphilosophy designed to bring into view (i.e., to illumine) the relationship between our everyday epistemic practices and those of philosophy such that we simultaneously come to recognize (a) what I call the pragmatic–transcendental self–standingness (...) of the everyday and (b) its philosophical–rational groundlessness. The Pyrrhonian illumination of the everyday is therapeutic in that it aims to purify our metadoxastic attitudes of dogmatism. (shrink)

Hume’s account of the origin and nature of our ideas of space and time is generally thought to be the least satisfactory part of his empiricist system of philosophy. The main reason is internal in that the account is judged to be inconsistent with Hume’s fundamental principle for the relationship between senses and cognition, the copy principle. This paper defends Hume against the inconsistency objection by offering a new systematic interpretation of Hume on space and time and illuminating more generally (...) the role of the copy principle in his philosophy. Humes Theorie des Wesens und des Ursprungs unserer Vorstellungen von Raum und Zeit wird generell zu den am wenigsten befriedigenden Teilen seiner empiristischen Philosophie gezählt. Der Hauptgrund dafür ist werkimmanent: Die Raum- Zeit-Theorie einerseits und Humes „copy principle“ andererseits – d.h. dasjenige Fundamental-Prinzip, das die Relation zwischen unseren Sinnen und unserem Denken regelt – werden als miteinander inkonsistent erachtet. Dieser Beitrag bietet eine neue, systematische Interpretation der Raum-Zeit-Lehre Humes und eine umfassendere Darstellung der Rolle des „copy principles“ in seiner Philosophie an. Auf diese Weise wird Hume gegen den Vorwurf der Inkonsistenz verteidigt. (shrink)

In Treatise 1.4.2, David Hume seeks to explain how we come to believe in the external existence of bodies. He offers a complicated psychological account, where the imagination operates on the raw data of the senses to produce the ‘vulgar’ belief in the continued existence of the very things we sense. On behalf of philosophers, he presents a perceptual relativity argument that purports to show that the vulgar belief is false. I argue that scholars have failed to appreciate Hume's peculiar (...) formulation of the perceptual relativity argument and its relation to his psychological account of the vulgar belief. On my interpretation, in order to account for all the premises that Hume explicitly offers, the argument is best interpreted as beginning with a reductio that opposes the effects of the senses and the imagination in the vulgar belief. Thus Hume can be interpreted as identifying an ‘antinomy’ in the habits of the vulgar mind that produce belief in bodies. (shrink)

Hume’s views concerning the existence of body or external objects are notoriously difficult and intractable. The paper sheds light on the concept of body in Hume’s Treatise by defending three theses. First, that Hume’s fundamental tenet that the only objects that are present to the mind are perceptions must be understood as methodological, rather than metaphysical or epistemological. Second, that Hume considers legitimate the fundamental assumption of natural philosophy that through experience and observation we know body. Third, that many of (...) the contradictions and difficulties that interpreters attribute to Hume’s concept of body should be attributed instead, as Hume does, to every system of philosophy.

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.

How is it possible for David Hume to be both withering skeptic and constructive theorist? I recommend an answer like the Pyrrhonian answer to the question how it is possible to suspend all judgment yet engage in active daily life. Sextus Empiricus distinguishes two kinds of assent: one suspended across the board and one involved with daily living. The first is an act of will based on appreciation of reasons; the second is a causal effect of appearances. Hume makes the (...) same distinction, only he extends the sort of assent involved in daily life to theoretical matters as well. He is a skeptic both in finding no reason to grant the first sort of assent and in being subject to the second. (shrink)
