There is often a difference between what 'simple moral arithmetic' says and
what people are actually prepared to do.
Take the classic example of the runaway train heading down a track towards
a large group of people.
In scenario one, there is a set of points which will divert the train onto a different
track with only one person on it instead of many. You have a switch which will
divert the train onto the other track, saving the many and sacrificing the one.
In scenario two, you can stop the train by pushing a person off a bridge onto the
tracks in front of the train which will cause it to stop and save the many while sacrificing
the one.
According to simple moral accounting the two scenarios are functionally identical in that
you can make choice to act and kill the one [who would otherwise live] to save the
many.
However people overwhelmingly opt to flip the switch in scenario one, but refuse to
throw the person off the bridge in scenario two.
This is often put down to people not being able to be rational and correctly reason things
through... But an alternative suggestion which I believe has merit is that there is a
fundamental difference between the two scenarios from the perspective of the person
being asked the question. Flicking a switch and throwing a person off a bridge are entirely
different acts on an emotional level.
It's easy to do moral calculus and decide that the greater good, in lives saved is served by
an act... It's another altogether to actually do it.
In Isaac Asimov's I Robot series, a character discusses the fact that a 3 laws robot would kill
a rampaging murderer if that was the only way to save other people from being killed.
But that the conflict in the robots mind that would result would cause it to cease to function
after it had saved the people in danger.
It might be the optimum choice from a simple 'probable numbers saved' perspective to kill the
baby... But it might very well destroy the person that did it.
