|Morals: morals refers to a more or less coded set of rules, action maxims, duties and prohibitions within a society or group. Most of these rules are unconsciously internalized among the members of the society or group. Their justification and the possible assessment of actions are reflected in ethics and meta ethics. See also values, norms, rights, ethics.|
