Descartes’s First Meditation employs a series of arguments designed to generate the worry that the senses might not provide sufficient evidence to justify one’staking as certain one’s beliefs about the way the world is. As the meditator considers what principle describes the conditions under which it is possible to attain certain knowledge, one after another doubt-generating device is ushered in, until at last he finds himself like someone caught in a whirlpool, able neither to stand firm nor to swim out. In this paper, I examine one of those devices, namely, what is often referred to as the Madness Argument. In particular, I want to discuss its relation to the Dream Argument and its function in the Meditations as a whole. My position stands in contrast to the interpretations of Anthony Kenny, Margaret Wilson, Michael Williams, and, more recently, Janet Broughton and Catherine Wilson.

In my essay I look at the specifics of the dispute between the Scottish metaphysician Andrew Baxter and the mathematician Colin MacLaurin in an attempt to identify the source or sources of their contradictory, yet in both cases Newtonian, positions regarding occasionalism. After some general introductory remarks about each thinker, I examine the metaphysical implications that Baxter sees as following from Newton's concept of vis inertiæ. Following this, I look at MacLaurin's commitment to the role of sense experience in natural philosophy. Finally, I discuss the different passages from Newton's Opticks on which the two thinkers focus.

The answer which Joseph Almog gives to the question which serves as the title of his recent book What Am I? (subtitled: Descartes and the Mind-Body Problem) is based upon his interpretation of (1) and objection to Descartes' argument for the distinction of the mind and the body raised by Antoine Arnauld, as well as Descartes' response to it, and (2) Descartes' letters of 9 February 1645 to Denis Mesland. I will argue that both of these interpretations are incorrect, and as such do not support the conclusions which Almog claims to draw from them. The answer, then to the question of what I am which Almog provides is, I believe, not one Descartes would have held, nor one which his writings support. (Published Online October 13 2005).

Hans Hahn, mathematician, philosopher and co-founder of the Vienna Circle, attempted to reconcile the validity and applicability of both logic and mathematics with a strict empiricism. This article begins with a review of this attempt, focusing on his view of the relation of language to logic and his answer to the question of why we need logic. I then turn to some recent work by Stephen Yablo in an attempt to show that Yablo's fictionalism, and in particular his use of metaphor, can shed light on Hahn's philosophy of logic

The barn/barn façade thought experiment is familiar to most epistemologists. It is intended to present a counterexample to certain causal theories of knowledge; in it, a father driving through the countryside with his son says, ‘That's a barn’ while pointing to a barn. Unbeknownst to the father, however, a film crew is working in the area, and it has constructed several barn façades. While the father did correctly point to a barn when he made his assertion, he could have just as easily pointed to a barn façade, and so, many hold, he does not know that the structure at which he is pointing is in fact a barn. If this is so, then it follows that true beliefs formed from reliable causal processes may still not qualify as knowledge.

This article begins by examining James Beattie's conception of speculative ethics, which he regards as the study of the foundation and nature of virtue. This leads to a discussion of the moral sense, or conscience, which Beattie claims is part of the nature of every rational being and which is designed to lead us to a virtuous life. Given this, I ask why Beattie thought himself warranted, or even needed, to dispense practical ethical advice. Answering this involves looking at Beattie's views on the importance of proper education, as well as the role played by his acceptance of providential naturalism. Beattie's answer is not only consistent with his ‘lecturing others’ as to their practical duties, his understanding of the relation between the speculative and the practical also allows him to respond to what contemporary ethicists call the Application Problem. A comparison with Reid's ethical thought will help bring out this latter point.
