This is an assignment that are teacher gave to us.
Thomson’s Violin
One day, you wake up in hospital. In the nearby bed lies a world famous violinist who is connected to you with various tubes and machines.
To your horror, you discover that you have been kidnapped by the Music Appreciation Society. Aware of the maestro’s impending death, they hooked you up to the violinist.
If you stay in the hospital bed, connected to the violinist, he will be totally cured in nine months. You are unlikely to suffer harm. No one else can save him. Do you have an obligation to stay connected?
I would choose to stay connected to him and save him. It is not my obligation technically but I feel that as a human being it would be the right thing to do. Being in a hospital bed for 9 months would really get on my nerves and I would need to pass the time. I think I would talk to him about music, Christiantity, and other stuff. I don't know if I would except any bribes unless I really needed money. I know at some times I would want him to die so I could get out of the hospital and return to my normal life but I don't think I would ever actually mean it. I would also would want someone to do the same and to try and save me if that situation were to happen to me. So yes I would consider it to be my obligation to stay because of me being a human being.
