Moraal ja eetika.

It its first, descriptive usage, morality means a code of conduct which is held to be authoritative in matters of right and wrong. Morals are created by and define society, philosophy, religion, or individual conscience. An example of the descriptive usage could be "common conceptions of morality have changed significantly over time."

It its second, normative and universal sense, morality refers to an ideal code of conduct, one which would be espoused in preference to alternatives by all rational people, under specified conditions. In this "prescriptive" sense of morality as opposed to the above described "descriptive" sort of sense, moral value judgments such as "murder is immoral" are made. To deny 'morality' in this sense is a position known as moral skepticism, in which the existence of objective moral "truths" is rejected.

It its third usage, 'morality' is synonymous with ethics, the systematic philosophical study of the moral domain.

--------------------------------------------

Ethics is the major branch of philosophy, encompassing proper conduct and good living. It is significantly broader than the common conception of ethics as the analyzing of right and wrong. A central aspect of ethics is "the good life", the life worth living or that is simply satisfying, which is held by many philosophers to be more important than moral conduct.
