Morality
The concept of Morality comes from the Latin word moralitas, which means "manner, character, or suitable conduct." Morality refers to the process of distinguishing between intentions, choices, and behaviours that are seen as proper (right) and those that are regarded as improper (wrong). It is possible for a person's morality to originate from a code of behaviour that is associated with a specific philosophy, religion, or culture. Alternatively, a person's morality may originate from a standard that they feel should be applicable to all societies and cultures. It's possible that "goodness" and "rightness" are particular synonyms for the concept of "morality."
Meta-ethics is the study of abstract issues such as moral ontology and moral epistemology. Normative ethics, on the other hand, is the study of more concrete systems of moral decision-making such as deontological ethics and consequentialism. Both of these branches of study fall under the umbrella of moral philosophy. The dictum that "one should treat others as one would want other people to treat oneself" is an example of a normative ethical theory. "One should treat others as one would like other people to treat oneself."
Amorality can be defined in a variety of ways, but generally it refers to a lack of awareness of, indifference towards, or disbelief in any particular set of moral standards or principles. Immorality, on the other hand, is the active opposition to morality (that is, opposition to that which is good or right).
