This is the definition of objective morality.
A proposition is objective if its truth value is independent of the person uttering it. A fact is objective in the same way. For morality to be objective, moral propositions such as "Killing is bad","Stealing is bad", etc... need to be true independently of the person who is stating them.
Science can prove moral objective facts just as they do in court with showing how the weapon used fits the wound and the wound killed the person. The persons DNA and finger prints are on the weapon. These are facts no human can challenge. All we have to do is show that the persons wellbeing was ffectedby the moral act and science can prove what affects peoples wellbeing such as assault breaks bones, abuse leaves bruises and both traumatize people.
So why would you trust a surgeon to cut you open and perhaps work on your heart. Why do we trust traveling in areoplanes if science did not discover how arodynamics works. How does scientists land a satelite on Mars in the exact spot if they did not understand how gravity works. These are all scientific facts that allow scientists to do things according to maths and calculations that stand regardless of a persons personal opinion.
Science itself is not making any comments about morality. It is a tool we can use to show that a moral view a person has will caused damage to another person beyond their opinion. So if a persons moral view is that there is nothing wrong with driving a car fast, we can show through scientific tests with cars on speed and time/distance for breaking that speed makes it more risky and likely you are going to have a crash. In fact years of statistics show it is a fact and when we reduce speed it is one proven way to reduce deaths by car accidents. So that disproves the person who says speed is not a bad thing.
No all you have done is adjusted the way heat affects the water. The scientific fact is not that there are different ways to heat water. The scientific fact is we can only heat water to the boiling point by heat. So if someone says we can boil water by ice or by staring at it it can be scientifically proven as a fact that only heat can boil water and this will objectively prove the person as wrong because it is not anyones personal opinion that heat boils water it is an independent fact outside human views that comes from science which discovered and verified that only heat boils water. We can argue about how that heat can boil water such as by fire, cook top or microwave but the fact remains we need heat. If we lower boiling points we still need heat to bring it to the new temperature.
The scientific measurement and in the case of rape it will be a medical practictioner and a psychologist ill do an examination and tests and will determine what damage is done. Just like a mechanic does tests to see what is wrong with your car. From that we will know what is wrong. Rape will cause damage as it is an act of force which means against a persons will. They will try to fight and the attacker will do damage. It is often the psychological damage that can last years ie women is scared to go out at night, to have relationships, loses confidences, may turn to drugs, self abuse etc ect. This is determined by a psychological evaluation which will stand up in court or for insurance claims.
People with expert know how that have studied at UNi for years like doctors, geneticists, psychologists, psychiatrists, biologists and neorologists.
I think I have already stated that I am not forcing anyone to do or believe anything. It is just a fact that gets put out there in the universe like that water needs heat to boil. people can takee it or leave it. peeople can choose to still believe that ice boils water. In fact objective moraly does not work if it is forced on people as part of having objective morality is conscience and free will. The right to choose right or wrong and to live with your conscience.
That cannot be the case as most societies are continually telling us what we can and can't do as far as the law. They are saying to everyone regardless of their personal views that certain things are wrong and if you do them you will be punished.
The ironic thing about subjective morality is we end up with more laws, rules and regulations than an objective system becuase we have to protect just about every view. Such as anti descriminations laws, equal rights, council by laws, political legislations, and an ever increasing legal system that gets more and more complicated.
The funny thing is you are objecting to my view that there is objective morality when you support subjective morality that should allow and accept different views no matter what they are even if you disagree, even if they are horrible to you. It is almost as though you want me to give up my position and take on yours which totally against subjective morality.
I believe it is objective from what have said, not becuase it is my view but becuase I respect things like science which can inform people of certain verifiable facts. You have every right to have your thesis and hold you views. At the end of the day we may disagree but that is OK too.
