A comprehensive world view or worldview is the fundamental cognitive orientation of an individual or society encompassing the entirety of the individual or society's knowledge and point of view. A world view can include natural philosophy; fundamental, existential, and normative postulates; or themes, values, emotions, and ethics. The term is a calque of the German word [ˈvɛlt.ʔanˌʃaʊ.ʊŋ], composed of ('world') and ('view' or 'outlook'). The German word is also used in English.
It is a concept fundamental to German philosophy and 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.
The founder of the idea that language and worldview are inextricable is the Prussian philologist, Wilhelm von Humboldt (1767–1835). Humboldt argued that language was part of the creative adventure of mankind. Culture, language and linguistic communities developed simultaneously, he argued, and could not do so without one another. In stark contrast to linguistic determinism, which invites us to consider language as a constraint, a framework or a prison house, Humboldt maintained that speech is inherently and implicitly creative. Human beings take their place in speech and continue to modify language and thought by their creative exchanges. Worldview remains a confused and confusing concept in English, used very differently by linguists and sociologists. It is for this reason that Underhill suggests five subcategories: world-perceiving, world-conceiving, cultural mindset, personal world, and perspective (see Underhill 2009, 2011 & 2012).
Edward Sapir also gives an account of the relationship between thinking and speaking in English.
