For the general context, see Romanticism.

In the philosophy, art, and culture of German-speaking countries, German Romanticism was the dominant movement of the late 18th and early 19th centuries. German Romanticism developed relatively late compared to its English counterpart, coinciding in its early years with the movement known as German Classicism or Weimar Classicism. In contrast to the seriousness of English Romanticism, the German variety is notable for valuing humor and wit as well as beauty.

The early German romantics tried to create a new synthesis of art, philosophy, and science, looking to the Middle Ages as a simpler, more integrated period. As time went on, however, they became increasingly aware of the tenuousness of the unity they were seeking. Later German Romanticism emphasized the tension between the everyday world and the seemingly irrational and supernatural projections of creative genius. Heinrich Heine in particular criticized the tendency of the early romantics to look to the medieval past for a model of unity in art and society.

Bertrand Arthur William Russell, 3rd Earl Russell, OM, FRS (18 May 1872 – 2 February 1970) was a British philosopher, logician, mathematician, historian, and social critic. At various points in his life he considered himself a liberal, a socialist, and a pacifist, but he also admitted that he had never been any of these in any profound sense. He was born in Monmouthshire, into one of the most prominent aristocratic families in Britain.

Russell led the British "revolt against idealism" in the early 20th century. He is considered one of the founders of analytic philosophy along with his predecessor Gottlob Frege and his friend Ludwig Wittgenstein, and is widely held to be one of the 20th century's premier logicians. He co-authored, with A. N. Whitehead, Principia Mathematica, an attempt to ground mathematics on logic. His philosophical essay "On Denoting" has been considered a "paradigm of philosophy." His work has had a considerable influence on logic, mathematics, set theory, linguistics, computer science (see type theory and type system), and philosophy, especially philosophy of language, epistemology, and metaphysics.
