2. The Plank of Carneades
There are two shipwrecked sailors, A and B, treading water in the middle
of the ocean. They both see a plank that can only support one of them
and both of them swim towards it. Sailor A gets to the plank first.
Sailor B, who is going to drown, pushes A off and away from the plank
and, thus, ultimately, causes A to drown. Sailor B gets on the plank and
is later saved by a rescue team.
Can Sailor B can be tried for murder?
