Universal Bundle Theory holds that objects are fundamentally identical with bundles of universals. Universals are multiply instantiable properties. One popular objection to UBT concerns the possibility of distinct indiscernibles. There are mainly two replies in the literature, corresponding to two representative UBTs, which I shall call the Identity-View and the Instance-View. Each view faces serious problems. This paper proposes a new version of UBT and argues that it is better than these other two versions.

According to the thesis of powerism, our world is pervaded by causal powers which are metaphysically basic. The aim of this paper is to defend the existence of the self, defined as a substantial entity, and its mental powers. This claim, which may seem a bold one, should not be deemed as inconsistent with scientific evidence. In fact, this approach does not ignore empirical knowledge, but is not bound only to it in order to understand entities, properties, and the relationship (...) between them. Aristotelian powerism may show that the self, as the subject of one’s mental acts, is a substance that has an essential nature. Firstly, we shall analyze the immediate evidence we have in support of the existence of the self as a substantial entity. We will show that the self is a substance because it possesses an essential character, i.e. an individual essence. We will take into account the Aristotelian perspective of substance, trying to show how the presence of a necessary property that makes every subject identical to itself and the phenomenal features of one’s private experience point to the existence of a substantial entity that corresponds to the self. Secondly, we will try to justify the adoption of a metaphysical theory of causation based on powers, analyzing it in comparison with the main competing theories, namely hypotheticalism and nomism. Then, we shall proceed to show the causal properties of the substance in question, namely the mental powers. In fact, thirdly, we will embrace the thesis of powerism by defending the existence of a set of mental powers that should be attributed to the self. We will describe the main features of mental powers and we will show that they are conceivable as the pure intentional acts we perform by directing an intentional state towards an intentional object. In this way we show how a classic problem of philosophy of mind, relevant to science as well, can be addressed in an original way by a metaphysical approach involving powers. (shrink)

Co-Directors: Alexander Pruss & Tim O’Connor Committee: C. Stephen Evan’s, Todd Buras, -/- The current state of consciousness research is at an impasse. Neuroscience faces a variety of recalcitrant problems regarding the neurobiological binding together of states of consciousness. Philosophy faces the combination problem, that of holistically unifying phenomenal consciousness. In response, I argue that these problems all result from a naturalistic assumption that subjects of consciousness are built up out of distinct physical parts. I begin by developing a Husserlian (...) mereology of part-whole relations, which I apply to both an ontology of the holistic unity of the subjects of consciousness and the holistic unity of phenomenal consciousness itself. After a detailed analysis of the ontology and neuroscience of phenomenally unified consciousness, I argue against the three major naturalist views: physicalism, Russellian panpsychism, and emergentism. I develop various arguments demonstrating that these views each fail to account for the possibility of subjects of phenomenally unified consciousness. In the final chapter, I show how these arguments entail that the subject of phenomenal unity must be partless, must be a simple holistic unity. In turn, this provides a defense of substance dualism or at least something near enough. Given the widespread rejection of mind-body dualism, I answer certain neurological objections and conclude by sketching the details of an underexplored neo-Aristotelian form of substance dualism. I conclude that each of us, indeed every subject of phenomenally unified consciousness, is not made up of distinct parts. Not a brain. Not a body. Every embodied subject of phenomenally unified consciousness is a bodily soul. (shrink)
