This short yet wide-ranging book is a rewarding read; philosophers interested in current debates on the notions of personhood and personal identity and in the practical--that is, social, legal, and political--ramifications of these notions will find this book compelling and thought-provoking. The style is engaging and the abundance of real-life examples makes the discussion interesting. . . . it is an original, timely, and engaging contribution to the debate on personhood and personal identity. I am confident that it can be usefully used in undergraduate and early graduate courses; I hope also that it may be read by a broader public and successfully demonstrate that philosophy as a discipline and a practice is indeed relevant to our lives.
