Can we understand what makes someone the same person without understanding what it is to be a person? Prereflectively we might not think so, but philosophers often accord these questions separate treatments, with personal-identity theorists claiming the first question and free-will theorists the second. Yet much of what is of interest to a person—the possibility of survival over time, compensation for past hardships, concern for future projects, or moral responsibility—is not obviously intelligible from the perspective of either question alone. Marya (...) Schechtman encourages us to adopt a more unified perspective. (shrink)

What does it mean to say that this person at this time is 'the same' as that person at an earlier time? If the brain is damaged or the memory lost, how far does a person's identity continue? In this book two eminent philosophers develop very different approaches to the problem.

Marya Schechtman takes issue with analytic philosophy's emphasis on the first sort of question to the exclusion of the second.

Fregoli delusion is the mistaken belief that some person currently present in the deluded person's environment is a familiar person in disguise. The stranger is believed to be psychologically identical to this known person even though the deluded person perceives the physical appearance of the stranger as being different from the known person's typical appearance. To gain a deeper understanding of this contradictory error in the normal system for tracking and identifying known persons, we conducted a detailed survey of all (...) the Fregoli cases reported in the literature since the seminal Courbon and Fail paper. Our preliminary reading of these cases revealed a notable lack of definitional clarity. So, we first formulated a classification scheme of different person misidentification delusions so as to identify those cases that qualified as instances of Fregoli according to the above characterization: the mistaken belief that a known person is present in the environment in a different guise to his or her typical appearance. We identified 38 clear cases of this type and set out to answer a series of questions motivated by current hypotheses about the origin of the Fregoli delusion. We asked whether the patients misidentified particular strangers, made reference to the misidentified known persons using wigs or plastic surgery , misidentified many different strangers or only one, showed other symptoms , and made inferences about the motives of the known persons in disguise. We conclude by discussing the implications of our findings for current hypotheses concerning the origin of the Fregoli delusion. (shrink)

J. T. Ismael's monograph is an ambitious contribution to metaphysics and the philosophy of language and mind. She tackles a philosophical question whose origin goes back to Descartes: What am I? The self is not a mere thing among things--but if so, what is it, and what is its relationship to the world? Ismael is an original and creative thinker who tries to understand our problematic concepts about the self and how they are related to our use of language in (...) particular. (shrink)

What justifies our holding a person morally responsible for some past action? Why am I justified in having a special prudential concern for some future persons and not others? Why do many of us think that maximizing the good within a single life is perfectly acceptable, but maximizing the good across lives is wrong? In these and other normative questions, it looks like any answer we come up with will have to make an essential reference to personal identity. So, for (...) instance, it seems we are justified in holding X responsible for some past action only if X is identical to the person who performed that action. Further, it seems I am justified in my special concern for some future person only if he will be me. Finally, many of us think that while maximization within a life affects only one person, a metaphysical unity, maximization across lives affects many different, metaphysically distinct, persons, and so the latter is wrong insofar as it ignores this fundamental separateness of persons.

Personal identity deals with questions about ourselves qua people (or persons). Many of these questions are familiar ones that occur to everyone at some time: What am I? When did I begin? What will happen to me when I die? Discussions of personal identity go right back to the origins of Western philosophy, and most major figures have had something to say about it. (There is also a rich literature on personal identity in Eastern philosophy, which I am not competent (...) to discuss. Collins 1982 is a good source.). (shrink)
