Ethics
I'm sure mostly everyone has heard of trolly problems
It states that a trolly is moving towards 5 people but you can pull a lever and kill one person, save 5
mostly people would pull the lever
but it's because it feels like a math problem not anything real
for example should someone be forced to donate all their organs to save five people?
emotivism explains ethics as emotional responses so that is why when a problem is more real the answer sometimes change from when its less realistic
my example and trolly problem have the similar fandamental mechanism save five person for one
