This book provides an essential, comprehensive discussion on thought experiments and how they have featured throughout the history of the personal identity debate in analytic philosophy. Although many philosophical arguments employ thought experiments as a valuable methodological tool, there is a lack of focused discussion on the significant role these experiments play in the personal identity debate specifically. This book covers a range of central theories and examines how thought experiments have been featured throughout each.The author discusses and responds to pivotal works on personal identity such as John Locke’s Essay Concerning Human Understanding, Derek Parfit’s Reasons and Persons, as well as more recent arguments in the discussion. The book also explores how thought experiments are used for related debates in other philosophical traditions. Thought Experiments and Personal Identity will be of interest to scholars and advanced students working in contemporary philosophy of mind and metaphysics, as well as those with an interest in philosophical methodology.
