A worldview or a world-view or Weltanschauung is the fundamental cognitive orientation of an individual or society encompassing the whole of the individual's or society's knowledge, culture, and point of view. A worldview can include natural philosophy; fundamental, existential, and normative postulates; or themes, values, emotions, and ethics.
The term worldview is a calque of the German word Weltanschauung ˈvɛltʔanˌʃaʊ.ʊŋ, composed of Welt ('world') and Anschauung ('perception' or 'view'). The German word is also used in English. It is a concept fundamental to German philosophy, especially epistemology and refers to a wide world perception. Additionally, it refers to the framework of ideas and beliefs forming a global description through which an individual, group or culture watches and interprets the world and interacts with it as a social reality.
Within cognitive philosophy and the cognitive sciences is the German concept of Weltanschauung. This expression is used to refer to the "wide worldview" or "wide world perception" of a people, family, or person. The Weltanschauung of a people originates from the unique world experience of a people, which they experience over several millennia. The language of a people reflects the Weltanschauung of that people in the form of its syntactic structures and untranslatable connotations and its denotations.
The term Weltanschauung is often wrongly attributed to Wilhelm von Humboldt, the founder of German ethnolinguistics. However, Humboldt's key concept was Weltansicht. Weltansicht was used by Humboldt to refer to the overarching conceptual and sensorial apprehension of reality shared by a linguistic community (Nation). On the other hand, Weltanschauung, first used by Immanuel Kant and later popularized by Hegel, was always used in German and later in English to refer more to philosophies, ideologies and cultural or religious perspectives, than to linguistic communities and their mode of apprehending reality.
