David Simon Oderberg (born 1963) is an Australian philosopher of metaphysics and ethics based in Britain since 1987.
[3] Oderberg applies his classical viewpoint to some controversial ethical issues: abortion, euthanasia, animal rights, capital punishment and the just war theory.
[5] He aims to refute views like those of Peter Singer, who suggests that we deny that it is always wrong to intentionally kill innocent human beings.
On the subject of euthanasia, he argues that it too is immoral, because, like abortion, it involves the intentional killing of an innocent human being.
Furthermore, he believes the current scientific definition of brain death is unsatisfactory both on metaphysical grounds and from an ethical point of view.
