Ethics comes from the Greek ethos which means customs and aims to study the moral and human action. His study traces the origins of moral philosophy in classical Greece and its historical development has been mixed. It''s good to keep in mind the differences between ethics and morality thus: Ethics, is the way each person interprets the moral norm, that is, the way that meets a standard that is prepared by the outside world, so that a person is ethical if it complies with the rules or moral standards imposed by society. Moral: It is a set of rules to be established from our ancestors which refers to things that they are "good" or "bad" and which have spread from generation to generation. The difference is that the person living in any community has a set of moral rules which it says must be met now, ethics involves the thought of each person, that is, even though people know which are moral standards for some reason decides whether or not to carry them out ...
For example: A man of 25 years college graduate is sitting on a bus at a glance where all places are occupied now, get on the bus an old lady, then, knows that the moral standards indicate that should give the wing seat lady but: a) is unethical and decides to carry out the moral standard and give the seat to the lady. b) The Lord has no ethics that does not meet the moral standards that were created by our ancestors and not give the seat to the lady. Should distinguish, however, between the ethical and moral: even in common parlance often taken as synonyms, the preferred use of the term to designate all moral values, norms and customs of an individual or human group. We reserve the word ethics, however, to allude to attempt rational (ie, philosophical) to base morality understood as a phenomenon of morality or ethos ("character, way of being '').
In other words, ethics is a theming of the ethos, is to question the assumptions on which moral action is based, is achieved with this criticism that these precepts are more suitable to a particular social project. An ethical doctrine develops and verifies claims or judgments. This sentence ethics, moral judgments or policy statement is a statement containing words such as ''bad'', ''good'', ''right'', ''wrong'', ''required'', ''enabled'', etc, relating to an action or decision. When using ethical judgments are moral values to people, situations, things or actions. Thus, moral judgments are being established where, for example, says: "That politician is corrupt," "That man is unpresentable", "Your presence is welcome", etc.. These statements are the words ''corrupt'', ''unpresentable'' and ''commendable'' that involve assessments of morality. Ethics examines the moral and determines what is good and from this point of view, how to act. That is, theory or science of human behavior.
