A deep blog post is coming on Wednesday. This will have to suffice for now.
CASE 1
A train is barreling down a track towards FIVE unsuspecting people who are unaware of the situation. You see a lever which, if pulled, will switch the train towards another track and kill a single unsuspecting individual, who is lying on the second track (let's say he's sunbathing, who knows).
Your options are: Do nothing OR Pull the level. Death options are: 5 people OR 1 person
The people in this case will die with 100% certainty or live with 100% certainty. For example, no amount of yelling at them will get them to move.
The value of all lives is 100% equivalent. They are all equally wealthy, eloquent, loving, have same amount of children, etc.
You are the only person who can make this decision.
There are no other options - only these two.
All other variables are 100% and absolute, no loopholes.
CASE 2
You are visiting a hospital and enter a room with five ill people who need immediate transplants. They all need different organs, one needs a heart, another a liver, etc, etc. If they receive organs in the immediate term they will survive with 100% certainty. A man enters the hospital to visit his mother, walks by your door, and your x-ray vision shows that he is a perfect match for all five transplants in the room. You notice a butcher knife on a side table which if jabbed into this man's throat would kill him with 100% certainty, allowing for immediate harvesting of his organs, and the saving of five lives.
Your options are: Do nothing OR Use the knife. Death options are: 5 people OR 1 person
The people in this case will die with 100% certainty or live with 100% certainty. Meaning that if you choose to murder this unsuspecting individual his organs will save five lives with 100% certainty. He was also be unable to be saved by the hospital with 100% certainty. If you do nothing he will go about his life with 100% certainty. The five people in your room would then die with 100% certainty.
You know with 100% certainty that no other people will be walking down the corridor. You know with 100% certainty than your own body is not a perfect match for any of the organs.
The value of all lives is 100% equivalent. They are all equally wealthy, eloquent, loving, have same amount of children, etc.
You are the only person who can make this decision.
There are no other options - only these two.
All other variables are 100% and absolute, no loopholes.
-----------------
These cases are perfectly parallel. Being passive leads to five deaths. Becoming active kills one in order to save five. A net gain of 4. All people are 100% equivalent in this model. This means a true net gain of 4.
So, why is it that 95% of people would pull the level in the first case, but be unable to use the butcher knife in the second case.
Thoughts?
