Arthur Schopenhauer was a German philosopher. He is known for his 1818 work The World as Will and Representation, which characterizes the phenomenal world as the manifestation of a blind and irrational noumenal will. Building on the transcendental idealism of Immanuel Kant (1724–1804), Schopenhauer developed an atheistic metaphysical and ethical system that rejected the contemporaneous ideas of German idealism.

Johann Wolfgang von Goethe was a German polymath and writer, who is widely regarded as the greatest and most influential writer in the German language. His work has had a profound and wide-ranging influence on Western literary, political, and philosophical thought from the late 18th century to the present day. Goethe was a German poet, playwright, novelist, scientist, statesman, theatre director, and critic. His works include plays, poetry and aesthetic criticism, as well as treatises on botany, anatomy, and color.
