: Those who are morally opposed to abortion generally make several pivotal assumptions. This paper focuses on the assumption that we have full moral status throughout our existence. Coupled with the assumption that we come into existence at conception, the assumption about moral status entails that all human fetuses have full moral status, including a right to life. Is the assumption about moral status correct? In addressing this question, I respond to several arguments advanced, in this journal and other venues, by Alfonso Gómez-Lobo. Gómez-Lobo's reasoning resolves into two basic arguments: (1) an appeal to the practical necessity of early moral protection and (2) an appeal to our kind membership and potentiality. I respond to these in turn before offering further reflections.

If personal identity consists in non-branching psychological continuity, then the sharp breaks in psychological connectedness characteristic of Multiple Personality Disorder implicitly commit psychological continuity theories to a metaphysically extravagant reification of alters. Animalist theories of personal identity avoid the reification of alternate personalities by interpreting multiple personality as a failure to integrate alternative autobiographical memory schemata. In the normal case, autobiographical memory cross-classifies a human life, and in so doing provides access to a variety of interpretative frameworks with their associated clusters of general event memory and episodic memory. Multiples exhibit erratic behavior because they cannot access reliably the intersecting autobiographical memory schemata that permit graceful transitions between social roles, behavioral repertoire and emotional dispositions. Selves, in both normal and certain pathological cases, are best understood as semi-fictional narratives created by human animals to serve their social, emotional and physical needs.

The received view of multiple personality disorder (MPD) presupposes a form of realism, according to which the 'secondary personality' is an independent conscious entity joined to the psyche of the host. The received view of MPD is endorsed by the majority of psychologists, as are the major diagnostic criteria for MPD. Realism of this type, gives rise to a certain problem concerning the personal identity of the secondary personality, namely, who this individual is. It is argued that three broad answers to the Question of Who in the context of MPD have been proposed in the history of psychology and psychiatry: psychological realism (Janet and the Dissociationist School); psychological anti-realism (Freud and the Psychoanalytic School), and neural realism (Wigan, Sperry and Gazzaniga). These views are examined. In addition, the relationship of the Question of Who to the traditional problem of personal identity is examined. It is argued that philosophers such as Locke, Reid and Parfit have either overlooked or presupposed the Question of Who.

This paper outlines a multidimensional conception of Multiple Personality Disorder (MPD) that differs from the 'orthodox' conception in terms of the content of its commitment to the reality of the self. Unlike the orthodox conception it recognizes that selves are fuzzy entities. By appreciating the possibility that selves are fuzzy entities, it is possible to rebut a form of fictionalism about the self which appeals to clinical data from MPD. Realism about self can be preserved in the face of multiple personalities.

Marya Schechtman argues that psychological continuity accounts of personal identity, as represented by Derek Parfit's account, fail to escape the circularity objection. She claims that Parfit's deployment of quasi-memory (and other quasi-psychological) states to escape circularity implicitly commit us to an implausible view of human psychology. Schechtman suggests that what is lacking here is a coherence condition, and that this is something essential in any account of personal identity. In response to this I argue first that circularity may be escaped using quasi-psychological states even with the addition of the coherence condition. Second, I argue that there is something right about the coherence condition, and a major task of this paper is to identify its proper theoretical role. I do so by reflection on integration therapies for people with multiple personality disorder (MPD). The familiar distinction between the moral and the metaphysical concept of the person is developed alongside such reflection. Connecting these two issues I argue that coherence acts as a normative constraint on accounts of personal identity, but that the normative dimension of personhood is not essential to our notion of a person tout court.

Dissociative Identity Disorder (DID) (formerly known as Multiple Personality Disorder) is a condition in which a person appears to possess more than one personality, and sometimes very many. Some recent criminal cases involving defendants with DID have resulted in "not guilty" verdicts, though the defense is not always successful in this regard. Walter Sinnott-Armstrong and Stephen Behnke have argued that we should excuse DID sufferers from responsibility, only if at the time of the act the person was insane (typically delusional); otherwise the presumption should be that persons with DID are indeed responsible for their actions. We find their interpretation of DID and of the way in which the requirements for criminal insanity relate to this condition worrying and likely to result in injustice to DID sufferers. Our thesis is that persons with DID cannot be responsible for their actions if the usual features of the condition are present. A person with DID is a single person in the grip of a very serious mental disorder. By focusing on the features of DID which have, as we argue, the effect of deluding the patient, we try to show that such a person is unable to fulfill the ordinary conditions of responsible agency (namely, autonomy and self-control).

The condition known as Multiple Personality Disorder (MPD) or Dissociative Identity Disorder (DID) is metaphysically strange. Can there really be several distinct persons operating in a single body? Our view is that DID sufferers are single persons with a severe mental disorder. In this paper we compare the phenomenology of dissociation between personality states in DID with certain delusional disorders. We argue both that the burden of proof must lie with those who defend the metaphysically extravagant Multiple Persons view and that there is little theoretical motivation to yield to that view in light of the fact that the core symptoms of DID bear remarkable similarity to the symptoms of these other disorders where no such extravagance is ever seriously entertained.

One of the central problems of personal identity is to determine what we are essentially . In response to this problem, Lynne Rudder Baker espouses a psychological criterion, that is, she claims that persons are essentially psychological. Baker’s theory purports to bypass the problems of other psychological theories such as Dissociative Identity Disorder and the problem of individuating persons synchronically. I argue that the theory’s treatment of Dissociative Identity Disorder leads to untenable results, is invalid, and consequently fails to individuate persons.

In this paper we argue that dissociative identity disorder (DID) is best interpreted as a causal model of a (possible) post-traumatic psychological process, as a mechanical model of an abnormal psychological condition. From this perspective we examine and criticize the evidential status of DID, and we demonstrate that there is really no good reason to believe that anyone has ever suffered from DID so understood. This is so because the proponents of DID violate basic methodological principles of good causal modeling. When every ounce of your concentration is fixed upon blasting a winged pig out of the sky, you do not question its species' ontological status. James Morrow, City of Truth (1990).
