Martin, Brandon John Emile2024-12-102024-12-102024https://hdl.handle.net/10566/19782Non-reductionist theories of personal identity have become less popular than they once were. However, they are quick to discuss the implications of their theories on real problems, such as abortion, head transplants and other practical concerns. As I will go on to argue, I think they are too quick. I aim to show that non-reductionist theories cannot offer adequate guidance on our practical concerns, or if they do, they are severely limited in the kinds of guidance they can provide since their theories are compromised at either the metaphysical or logical level. Instead, I suggest that these theories focus on strengthening their positions before we can take their guidance seriously.enPersonal identityNon-reductionist theoriesReductionist theoriesPractical guidanceMetaphysicsThesis
