時代精神

Also known as zeit-geist; spirit of the age

In 18th- and 19th-century German philosophy, a Zeitgeist (; ; capitalized in German) is a way of referring to the intellectual, cultural, ethical and political climate of a given epoch in world history. It is often described as an invisible agent, force, or daemon that seems to dominate the characteristics of a particular period. The term is usually associated with Georg W. F. Hegel, contrasting with Hegel's use of Volksgeist ("national spirit") and Weltgeist ("world-spirit"), although the word itself predates Hegel and was popularized by Johann Gottfried Herder and Johann Wolfgang von Goethe.
