If 'ought' statements are indexed to the agent's own ends, then 'We ought to bomb London' (Nazi) and 'Nobody ever ought to bomb anything' (pacifist) would not contradict one another
When two statements directly oppose each other in a way that makes them both cannot be true at the same time—like saying 'it is raining' and 'it is not raining.'
Indexed to(as used in ethics)
Connected or adjusted according to something else; in this case, obligations that change based on how much risk someone is creating.
Nazi(as used in the example statement)
A member of the German fascist party that controlled Germany during World War II and committed horrific atrocities; used here as an example of a group with extreme moral views.
Pacifist(as used in the example statement)
Someone who believes violence and war are wrong and refuses to use force to solve problems.
But, as Russell plainly believes, there is a subject of debate between them, which means that relativistic readings of “good” and “bad” must (at least sometimes) be wrong. A similar problem afflicts his own subsequent analyses of “ought” and “right”. Since their “oughts” are indexed to different ends, it seems that when the Nazi says “We ought to bomb London” and the pacifist says “Nobody ever ought to bomb anything” they are not contradicting one another, though it is as clear as daylight that
