Main Difference
The main difference between Ethics and Etiquette is that the Ethics is a branch of philosophy that involves systematizing, defending, and recommending concepts of right and wrong conduct and Etiquette is a customary code of polite behaviour
Ethics
Ethics or moral philosophy is a branch of philosophy that involves systematizing, defending, and recommending concepts of right and wrong conduct. The field of ethics, along with aesthetics, concern matters of value, and thus comprise the branch of philosophy called axiology.Ethics seeks to resolve questions of human morality by defining concepts such as good and evil, right and wrong, virtue and vice, justice and crime. As a field of intellectual inquiry, moral philosophy also is related to the fields of moral psychology, descriptive ethics, and value theory.
Three major areas of study within ethics recognized today are:
Meta-ethics, concerning the theoretical meaning and reference of moral propositions, and how their truth values (if any) can be determined
Normative ethics, concerning the practical means of determining a moral course of action
Applied ethics, concerning what a person is obligated (or permitted) to do in a specific situation or a particular domain of action
Etiquette
Etiquette ( or , French: [e.ti.kɛt]) is a code of behavior that delineates expectations for social behavior according to contemporary conventional norms within a society, social class, or group.
The French word étiquette, literally signifying a tag or label, was used in a modern sense in English around 1750. Etiquette is behaviour that assists survival and has changed and evolved over the years.
