Define happiness and harm.
For me, something along the lines of being pleased with something, and wanting it to continue, versus being unpleased and wanting it to stop. For anyone else, it is up to them to define it.
and provide an algorithm to calculate its net amount.
1) Observe how happy or harmed a person is.
2) Add the value you come up with to the running total.
3) Repeat with another person.
Prove that defined happiness exists at all.
I define happiness to be the condition of being happy. People say they are happy. Thus, happiness exists.
Prove that such a calculation is always possible
I don't think it is always possible -- many times one can't get at much data, many times people are not forthcoming about their happiness, many times it doesn't even matter because like I said people are not supercomputers.
What is the point of this question?
and always leads to a unique result.
All events in the universe are unique. The results of all decisions are events. Thus all results are unique.
What is the point of this question?
Provide the time scale for running the calculation.
When my fiancee asks me to get her a glass of water, less than a second.
When a government decides whether or not to fund a mission to space, probably on the order of months or years.
What is the point of this question?
Provide contact details of the authority from where I can get the latest calculation results.
Whoever is making the calculation.
What is the point of this question?
Please explain to him concretely (1) how to detect and measure whose 'happiness' and 'harm' and (2) how to calculate an estimated net sum and (3) how to estimate the error of this calculation. Also specify the maximum error allowed. Prove the result is always possible and unique. Prove that humans can normally perform this calculation, and specify the required education (mathematics?).
Specify how a valid calculation result then points to one particular action in any given concrete situation and how he shall act if his result is invalid because it exceeds the maximum error allowed.
Consider a person trying to recognize a face. Or, a person trying to walk home in a city. Or, a person writing a poem. Or, a person doing anything people do.
Please explain to them concretely (1) how to detect and measure the utility of each feature that may contribute to the overall utility of any decision during the act (2) how to calculate a mathematical representation of the sum of those utilities and (3) how to estimate the error of this calculation. Also specify the maximum error allowed. Prove the result is always possible and unique. Prove that humans can normally perform this calculation, and specify the required education (mathematics?).
Specify how a valid calculation result then points to one particular action in any given concrete situation and how he shall act if his result is invalid because it exceeds the maximum error allowed.
Provide concrete samples of calculating the morally best action for different situations.
My fiancee is sick and wants some water. For her to get up and get it would be painful and tiring. For me to get it is trivial. The reward she will give me in love and companionship, and the reward I get from knowing I helped someone I care about, outweighs the trivial pain and energy of my walk to the refrigerator. I decide to get her water. Note that the template of this decision is most likely hard coded into my neural system by now and I will probably automatically help my fiancee without thinking.
Do you claim that there is an absolute moral rule for helping your fiancee get water?
A man is injured on the road. If I do not help him, his condition may worsen. If I do help him, I will be late to work. The reward I am likely to get in gratuity from him, and the reward I get from knowing that I helped someone, outweighs the harm caused by me being late to work since my job can wait. I decide to help the man. Note that the template of this decision is most likely hard coded into my neural system by now and I will probably automatically help injured people on the road without thinking.
Do you claim that there is an absolute moral rule for helping injured people on the road?
Many Americans are loosing jobs to foreign workers. If I prevent jobs from going to foreign workers, some people will be helped and some will be harmed. If I allow jobs to go to foreign workers, some people will be helped and some will be harmed. I decide that I can't make this decision in a split second and should research the issue until I feel I know enough to make a correct decision. At that point, I will probably have many meetings with many different people who will advise me. After that, I will reach a decision I feel maximizes happiness. If there are others like me, we will combine our decisions in a way we feel maximizes happiness given the constraint of democracy.
Do you claim that there is an absolute moral rule for international economics?
