Are you satisfied with Kants definition of personhood and moral community?What criteria should we use to determine whether another being (say, an alien from another planet) is rational or has self-consciousness? Using Kants definition of personhood, discuss whether it would be morally permissible: a) to use human embryos in stem cell research, b) to breed children in order to use their organs as spare parts, or c) euthanize elderly people with dementia who are no longer rational. Discuss also how Kant would respond to utilitarian Peter Singers support of these policies.
