This dissertation makes progress on the mind-body problem by examining certain key features of epistemic defeasibility, introspection, peer disagreement, and philosophical methodology. In the standard thought experiments, dualism strikes many of us as true. And absent defeaters, we should believe what strikes us as true. In the first three chapters, I discuss a variety of proposed defeaters—undercutters, rebutters, and peer disagreement—for the seeming truth of dualism, arguing that not one is successful. In the fourth chapter, I develop and defend a novel argument from the indefeasibility of certain introspective beliefs for the conclusion that persons are not complex objects like brains or bodies. This argument reveals the non-mechanistic nature of introspection. / text

Improvements in technology and the Internet have seen a rapid rise in the use of technology in various sectors such as medicine, the courts and banking. The conveyancing sector is also experiencing a similar revolution, with technology touted as able to improve the effectiveness of the land registration process. In some jurisdictions, such as New Zealand and Canada, the paper-based land registration system has been replaced with one in which creation, preparation, and lodgement of land title instruments are managed in a wholly electronic environment. In Australia, proposals for an electronic registration system are under way. The research question addressed by this thesis is what would be the impact on fraud of automating the registration process. This is pertinent because of the adverse impact of fraud on the underlying principles of the Torrens system, particularly security of title. This thesis first charts the importance of security of title, examining how security of title is achieved within the Torrens system and the effects that fraud has on this. Case examples are used to analyse perpetration of fraud under the paper registration system. Analysis of functional electronic registration systems in comparison with the paper-based registration system is then undertaken to reveal what changes might be made to conveyancing practices were an electronic registration system implemented. Whether, and if so, how, these changes might impact upon paper based frauds and whether they might open up new opportunities for fraud in an electronic registration system forms the next step in the analysis. The final step is to use these findings to propose measures that might be used to minimise fraud opportunities in an electronic registration system, so that as far as possible the Torrens system might be kept free from fraud, and the philosophical objectives of the system, as initially envisaged by Sir Robert Torrens, might be met.
