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 Weltanschauung, composed of Welt ('world') and Anschauung ('view' or 'outlook'). 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.
