RT Journal Article SR Electronic T1 Of souls, selves, and cerebrums: a reply to Himma JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 56 OP 60 DO 10.1136/jme.2004.006650 VO 31 IS 1 A1 F J Beckwith YR 2005 UL http://jme.bmj.com/content/31/1/56.abstract AB Ken Himma argues that a human being becomes a moral person at the commencement of brain activity. In response to Himma, the author offers (1) brief comments on Himma’s project, (2) an alternative account of the human person that maintains that a human being is a human person by nature as long as it exists, and (3) a counterexample to Himma’s position that shows it cannot account for the wrongness of the purposeful creation of anencephalic-like children. The author concludes with replies to two challenges to his position.
