High culture encompasses the cultural objects of aesthetic value, which a society collectively esteem as exemplary art. It may also include intellectual works considered to be of supreme philosophical, historical, or literary value, as well as the education which cultivates such aesthetic and intellectual pursuits. In popular usage, the term high culture identifies the culture of an upper class (an aristocracy) or of a status class (the intelligentsia); and also identifies a society’s common repository of broad-range knowledge and tradition (e.g. folk culture) that transcends the social-class system of the society. Sociologically, the term high culture is contrasted with the term low culture, the forms of popular culture characteristic of the less-educated social classes, such as the barbarians, the Philistines, and hoi polloi (the masses).
