The U.S. federal regulations require investigators conducting nonbeneficial research to obtain the assent of children who are capable of providing it. Unfortunately, there has been no analysis of which children are capable of assent or even what abilities ground the capacity to give assent. Why should investigators be required to obtain the positive agreement of some children, but not others, before enrolling them in research that does not offer a compensating potential for direct benefit? We argue that the scope of (...) children's research decision making should be based on the principles of respect for autonomy and nonmaleficence. These principles imply that the threshold for assent should be fixed at 14 years of age, and a dissent requirement should be adopted for all children in the context of nonbeneficial research.

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

Philosophical discussions of personal identity depend upon thought experiments which describe psychological vicissitudes and question whether the original person survives in the person resulting from the described change. These cases are meant to determine the types of psychological change compatible with personal continuation. Two main accounts of identity try to capture this distinction; psychological continuity theories and narrative theories. I argue that neither fully succeeds since both overlook the importance of a relationship I call “empathic access.” I define empathic access (...) and discuss its role in a complete account of personal identity.

It is often said that people are ‘not themselves’ when they are in situations which rob them of their self‐control. Strangely, these are also circumstances in which people are often said to be most fully themselves. This paper investigates the pictures of the self behind these two truisms, and the relation between them. Harry Frankfurt’s work represents the first truism, and standard objections to his work the second. Each of these approaches is found to capture one independent and widely employed (...) picture of the self. The connection each draws between being oneself and flourishing, however, suggests a point of contact between them. This point of contact is used to develop a third view of being oneself which integrates the insights of the other two. (shrink)

Drawing heavily on recent empirical research to update R.M. Hare's two-level utilitarianism and expand Hare's treatment of "intuitive level rules," Gary Varner considers in detail the theory's application to animals while arguing that Hare should have recognized a hierarchy of persons, near-persons, & the merely sentient.

When philosophers address personal identity, they usually explore numerical identity: what are the criteria for a person's continuing existence? When non-philosophers address personal identity, they often have in mind narrative identity: Which characteristics of a particular person are salient to her self-conception? This book develops accounts of both senses of identity, arguing that both are normatively important, and is unique in its exploration of a range of issues in bioethics through the lens of identity. Defending a biological view of our (...) numerical identity and a framework for understanding narrative identity, DeGrazia investigates various issues for which considerations of identity prove critical: the definition of death; the authority of advance directives in cases of severe dementia; the use of enhancement technologies; prenatal genetic interventions; and certain types of reproductive choices. He demonstrates the power of personal identity theory to illuminate issues in bioethics as they bring philosophical theory to life. (shrink)
