Jefferson Allen McMahan (/məkˈmɑːn/ mək-MAHN; born August 30, 1954) is an American moral philosopher.
In its first part, McMahan defends a mixed view of personal identity, claiming that individuals are what he calls "embodied minds".
[6] In relation to his contributions in bioethics, McMahan has also written on the subject of animal ethics, where he has argued against the moral relevance of species membership.
[10] He has additionally made a case for intervening in nature to alleviate the suffering of wild animals when doing so would not cause more harm than good.
Against Michael Walzer,[15] he claims that those who fight an unjust war can never meet the requirements of jus in bello.
[17] In the early 1980s, he wrote two books about the political situation at the time: British Nuclear Weapons: For and Against[18] and Reagan and the World: Imperial Policy in the New Cold War.
