I understand that there are two type of moral standards: social and humanistic.
The social moral standards are set up for establishing social stability. This includes laws, religion doctrines and common social customs (based on traditional ideology). The humanistic standard is based on our conscience, which belong to our nature. The former favors more on social needs, latter more on individual rights.
History of ethics seems to involve from strict collective (social) rules that prohibited most individual desires or needs, to be more tolerant on individual rights. Examples such as marriage, patriotism, homosexuality, religious, etc. all demonstrated this route.
