You say morals, I say ethics. The Conversation
According to this understanding, “ethics” leans towards decisions based upon individual character, and the more subjective understanding of right and wrong by individuals – whereas “morals” emphasises the widely-shared communal or societal norms about right and wrong. Put another way, ethics is a more individual assessment of values as relatively good or bad, while morality is a more intersubjective community assessment of what is good, right or just for all.
On ethics and morality. New Advent
A distinction must be made between ethics and morals, or morality. Every people, even the most uncivilized and uncultured, has its own morality or sum of prescriptions which govern its moral conduct. Nature had so provided that each man establishes for himself a code of moral concepts and principles which are applicable to the details of practical life, without the necessity of awaiting the conclusions of science. Ethics is the scientific or philosophical treatment of morality.
