Among the results of recent investigation of epistemic intuitions by experimental philosophers is the finding that epistemic intuitions show cultural variability between subjects of Western, East Asian and Indian Sub-continent origins. In this paper I ask whether the finding of this variation is evidence of cross-cultural variation in the folk-epistemological competences that give rise to these intuitions—in particular whether there is evidence of variation in subjects’ explicit or implicit theories of knowledge. I argue that positing cross-cultural variation in subjects’ implicit theories of knowledge is not the only possible explanation of the intuitions, and I suggest other explanations, including the hypothesis that each subject’s implicit theory of knowledge might contain a heterogeneous set of heuristics for ascribing knowledge. Variation in intuitions, then, might be the result of within-subject heterogeneity rather than across-subject heterogeneity.

Might it be that world itself, independently of what we know about it or how we represent it, is metaphysically indeterminate? This article tackles in turn a series of questions: In what sorts of cases might we posit metaphysical indeterminacy? What is it for a given case of indefiniteness to be 'metaphysical'? How does the phenomenon relate to 'ontic vagueness', the existence of 'vague objects', 'de re indeterminacy' and the like? How might the logic work? Are there reasons for postulating this distinctive sort of indefiniteness? Conversely, are there reasons for denying that there is indefiniteness of this sort?

In light of the long-lived, on-going debate surrounding the Aristotelian doctrines of prime matter and the four simple bodies (or 'elements'), the general message of this thesis is surprising: that Aristotle's theory is centred on neither. I argue that Aristotle does in fact have a substantial prime matter, but not the single, featureless, immutable prime matter of tradition.

Incommensurable theories are said to be both incompatible and incomparable. This is paradoxical, because, being incompatible, these theories must have the same subject-matter, yet incomparability implies that their subject-matter is different. This paper's proposed resolution of the paradox makes use of the distinction between internal subject-matter and external subject-matter for languages (frameworks) as outlined by W. Sellars. Incommensurability arises when two languages share the same external subject-matter but differ in internal subject-matter. When they share the same external subject-matter, they can be inconsistent (hence incompatible), and yet incomparable (because they are about distinct internal subject-matter). A substantial part of the paper is devoted to the technical development of the notion of inconsistency as a relationship between languages in contrast to the traditional notion of inconsistency between statements.

Aristotle’s Motivation for Matter Why does Aristotle make matter so central to his account of the natural world, making it a principle of nature and one of the four causes? Although there is considerable interest in how Aristotle conceives of matter, scholars rarely investigate why he thinks of it as fundamental to the natural world. Some simply ask why Aristotle thinks there must be matter (without asking how this fits into his account of the natural world). Other interpreters do not even agree that we should ask this question; they claim that Aristotle does not give reasons for needing matter because matter is an everyday notion we need not motivate. I think that in Physics I Aristotle gives us good reasons – perhaps even compelling ones – for thinking that matter is necessary for any understanding of the natural world. We, as interpreters, can use these reasons to understand <span class='Hi'>what</span> matter is for Aristotle, making progress where scholars have offered many incompatible interpretations. The first chapter of the dissertation presents my basic account of why Aristotle needs matter and <span class='Hi'>what</span> it is. I argue that Aristotle makes matter central to his natural philosophy because it is needed in order to understand change. Specifically, in order for there to be change, there must be something whose very nature is to undergo change. This is <span class='Hi'>what</span> matter is for Aristotle: the thing whose very nature is to undergo change (i.e., the thing whose proper activity is undergoing change). Since matter is picked out by its role in change, the very <span class='Hi'>same</span> thing will be matter and other things, based on <span class='Hi'>what</span> other roles it has. Just as the <span class='Hi'>same</span> <span class='Hi'>person</span> can be a doctor and a builder, so the <span class='Hi'>same</span> <span class='Hi'>person</span> can be a doctor and matter. This chapter also highlights the strength of my account by arguing against a rival interpretation of Aristotle’s motivation for matter, according to which matter is needed so that something persists through change. The second chapter argues for my interpretation through a close reading of Aristotle’s Physics I..
