Weltschmerz
Weltschmerz (from the German, meaning world-pain or world-weariness, pronounced[ˈvɛltʃmɛɐ̯ts]) is a term coined by the German author Jean Paul and denotes the kind of feeling experienced by someone who believes that physical reality can never satisfy the demands of the mind. This kind of world view was widespread among several romantic authors such as Lord Byron, Giacomo Leopardi, François-René de Chateaubriand, Alfred de Musset, Nikolaus Lenau, Hermann Hesse, and Heinrich Heine. It is also used to denote the feeling of anxiety caused by the ills of the world.
