Wilhelm Dilthey in the context of "Humboldt University of Berlin"

Historicity is the historical actuality of persons and events, meaning the quality of being part of history instead of being a historical myth, legend, or fiction. The historicity of a claim about the past is its factual status. Historicity denotes historical actuality, authenticity, factuality and focuses on the true value of knowledge claims about the past.

Some theoreticians characterize historicity as a dimension of all natural phenomena that take place in space and time. Other scholars characterize it as an attribute reserved to certain human occurrences, in agreement with the practice of historiography. Herbert Marcuse explained historicity as that which "defines history and thus distinguishes it from 'nature' or the 'economy'" and "signifies the meaning we intend when we say of something that is 'historical'." The Blackwell Dictionary of Western Philosophy defines historicity as "denoting the feature of our human situation by which we are located in specific concrete temporal and historical circumstances". For Wilhelm Dilthey, historicity identifies human beings as unique and concrete historical beings.

Lebensphilosophie (German: [ˈleːbm̩s.filozoˌfiː]; meaning "philosophy of life") was a dominant philosophical movement of German-speaking countries in the late 19th and early 20th centuries, which had developed out of German Romanticism. Lebensphilosophie emphasised the meaning, value and purpose of life as the foremost focus of philosophy.

Its central theme was that an understanding of life can only be apprehended by life itself, and from within itself. Drawing on the critiques of epistemology offered by Schopenhauer and Nietzsche, notable ideas of the movement have been seen as precursors to both Husserlian phenomenology and Heideggerian existential phenomenology.

Geistesgeschichte (from German Geist, "spirit" or "mind" [here connoting the metaphysical realm, in contradistinction to the material], and Geschichte, "history") is a concept in the history of ideas denoting the branch of study concerned with the undercurrents of cultural manifestations, within the history of a people, that are peculiar to a specific timeframe.

The term is largely untranslatable, sometimes translated as "intellectual history" or "history of ideas", and sometimes used synonymously with Problemgeschichte. The branch of study it denotes is often seen as having been inspired by the type of work done by Wilhelm Dilthey and his followers.

Johann Peter Heuschkel (4 January 1773 – 5 December 1853) was a German oboist, organist, music teacher and composer.

Heuschkel was born in Harras (Eisfeld) near Eisfeld. From 1792 he was oboist and later also organist in Hildburghausen. He is best remembered for being the teacher of Carl Maria von Weber (1796). He also taught music to the children of Duke Frederic. In 1818 he became court music teacher at Biebrich, where in later years he taught his grandson Wilhelm Dilthey. As a composer, Heuschkel wrote mostly wind music, oboe concertos, piano sonatas, and songs. He died, aged 80, in Biebrich.
