DescriptionThis dissertation comprises four stand-alone essays unified by a concern with metaphysical explanation: that is, with explanations which situate non-fundamental phenomena with respect to what is going on more fundamentally. The first essay, ‘Grounded Shadows, Groundless Ghosts’, discusses the prospects for explaining the four-dimensional manifest image in terms of an underlying reality with many more dimensions. I argue that this proposal does not face any special ‘explanatory gap’ concerning scrutability or arbitrariness. The second essay, ‘Two Approaches to Metaphysical Explanation’, clarifies and defends the importance of the distinction between a broadly ‘worldly’ approach to metaphysical explanation, involving the ‘generation’ of facts and other entities, and a broadly ‘representational’ approach, involving the ‘reduction’ of truths and their constituent notions. The third and fourth essays apply this distinction to two cases. ‘Generalism Without Generation’ argues in favour of a representational approach to explaining particular truths about individuals in terms of purely general truths. And ‘Against Grounding Physicalism’ argues in favour of a representational approach to explaining truths about consciousness in terms of broadly physical truths.
