^Landis, Judson R. (编). Current Perspectives on Social Problems Third. Belmont, California: Wadsworth Publishing Co. 1973: 2. ISBN 0-534-00289-7. Culture is the "social heritage" of society. It includes the complex set of learned and shared beliefs, customs, skills, habits, traditions, and knowledge common to the members of society. Within a culture, there may be subcultures made up of specific groups that are somewhat separate from the rest of society because of distinct traits, beliefs, or interests.
