I do not think that ethics can be quantified. This is because each person has their own limits. In order to make an ethical decision, someone has to simply follow their gut. Gut feelings will differ from person to person, which means that there is no set line that divides “okay” and “not okay”. I think people could use reason and language to figure out a general ballpark of what is unacceptable, but the actual limit will differ for every person. So, it is somewhat difficult to come up with a specific example pertaining to this…. I guess we could discuss abortion. It’s pretty much agreed that you can’t kill the baby once it’s born, but every person has a different opinion of when a fetus is considered a baby. Some people believe that it is from conception, others say from 3 months. It will be impossible for every person to simply agree on when a fetus is a person. Also, with this issue, I think that a slight majority of people believe that rape victims should be able to abort a pregnancy, but then again we encounter those who disagree. Those people will never be convinced to agree, even through the use of reason, because their gut is against it.
It’s extremely difficult to discuss ethics, because the person reading this could completely disagree with me and consider me as wrong. There is no right answer. GRRRR.
