 World view, the world view or world view is the fundamental cognitive orientation of an individual or society encompassing the whole of the individuals or society's knowledge and point of view. The world view can include natural philosophy, fundamental, existential, and normative postulates, or themes, values, emotions, and affix. The term is a calc of the German word Weltanschauung, composed of Welt-world-an-anschauung-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. World view remains the confused and confusing concept in English, used very differently by linguists and sociologists. It is for this reason that James W. Underhill suggests five sub-categories, world perceiving, world conceiving, cultural mindset, personal world, and perspective. World views are often taken to operate at a conscious level, directly accessible to articulation and discussion, as opposed to existing at a deeper, pre-conscious level, such as the idea of ground-engrave-tall psychology and media analysis. However, core worldview beliefs are often deeply rooted, and so are only rarely reflected on by individuals, and are brought to the surface only in moments of crises of faith.
