This document discusses the origins and meanings of ethics. It defines ethics as the study of human morality and motivation. There are two main approaches to ethics - the atheistic approach which sees man as only matter, and the theistic approach which sees man as having a spiritual dimension and being accountable to God. Ethics provides principles to guide human acts and serves as a foundation for law and society. While ethics and religion both aim to improve people and society, ethics relies on reason while religion is based on faith. Professional codes of ethics also guide conduct where laws are silent. Overall, ethics and morality are seen as vital for individuals, organizations and society.
