Geist (German pronunciation: [ˈɡaɪst]) is a German noun with a degree of importance in German philosophy. Its semantic field corresponds to English ghost, spirit, mind, intellect. Some English translators resort to using "spirit/mind" or "spirit (mind)" to help convey the meaning of the term.
Geist is also a central concept in Georg Wilhelm Friedrich Hegel's 1807 The Phenomenology of Spirit (Phänomenologie des Geistes). Notable compounds, all associated with Hegel's view of world history of the late 18th century, include Weltgeist "world-spirit", Volksgeist "national spirit" and Zeitgeist "spirit of the age".
