German idealism in the context of "Third Realm (Frege)"

Georg Wilhelm Friedrich Hegel (27 August 1770 – 14 November 1831) was a German philosopher and a major figure in the tradition of German idealism. His influence on Western philosophy extends across a wide range of topics—from metaphysical issues in epistemology and ontology, to political philosophy, to the philosophy of art and religion.

Hegel was born in Stuttgart. His life spanned the transitional period between the Enlightenment and the Romantic movement. His thought was shaped by the French Revolution and the Napoleonic wars, events which he interpreted from a philosophical perspective. His academic career culminated in his appointment to the chair of philosophy at the University of Berlin, where he remained a prominent intellectual figure until his death.

German philosophy, meaning philosophy in the German language or philosophy by German people, in its diversity, is fundamental for both the analytic and continental traditions. It covers figures such as Gottfried Wilhelm Leibniz, Immanuel Kant, Georg Wilhelm Friedrich Hegel, Karl Marx, Friedrich Nietzsche, Martin Heidegger, Ludwig Wittgenstein, the Vienna Circle, and the Frankfurt School, who now count among the most famous and studied philosophers of all time. They are central to major philosophical movements such as rationalism, German idealism, Romanticism, dialectical materialism, existentialism, phenomenology, hermeneutics, logical positivism, and critical theory. The Danish philosopher Søren Kierkegaard is often also included in surveys of German philosophy due to his extensive engagement with German thinkers.

Arthur Schopenhauer (/ˈʃoʊpənhaʊər/ SHOH-pən-how-ər; German: [ˈaʁtuːɐ̯ ˈʃoːpn̩haʊɐ] ; 22 February 1788 – 21 September 1860) was a German philosopher. He is known for his 1818 work The World as Will and Representation (expanded in 1844), which characterizes the phenomenal world as the manifestation of a blind and irrational noumenal will. Building on the transcendental idealism of Immanuel Kant, Schopenhauer developed an atheistic metaphysical and ethical system that rejected the contemporaneous ideas of German idealism.

Schopenhauer was among the first philosophers in the Western tradition to share and affirm significant tenets of Indian philosophy, such as asceticism, denial of the self, and the notion of the world-as-appearance. His work has been described as an exemplary manifestation of philosophical pessimism. Though his work failed to garner substantial attention during his lifetime, he had a posthumous impact across various disciplines, including philosophy, literature, and science. His writing on aesthetics, morality and psychology has influenced many thinkers and artists.

Walter Bendix Schönflies Benjamin (/ˈbɛnjəmɪn/ BEN-yə-min; German: [ˈvaltɐ ˈbɛnjamiːn] ; 15 July 1892 – 26 September 1940) was a German-Jewish philosopher, cultural critic, media theorist, and essayist. An eclectic thinker who combined elements of German idealism, Jewish mysticism, Western Marxism, and post-Kantianism, he made contributions to the philosophy of history, metaphysics, historical materialism, criticism, aesthetics and had an oblique but overwhelmingly influential impact on the resurrection of the Kabbalah by virtue of his life-long epistolary relationship with Gershom Scholem.

In popular culture and left journalism he often appears as an exemplar whose experience is representative of the tragedy of German-Jewish intellectuals under the Third Reich.

The history of philosophy is the systematic study of the development of philosophical thought. It focuses on philosophy as rational inquiry based on argumentation, but some theorists also include myth, religious traditions, and proverbial lore.

Western philosophy originated with an inquiry into the fundamental nature of the cosmos in Ancient Greece. Subsequent philosophical developments covered a wide range of topics including the nature of reality and the mind, how people should act, and how to arrive at knowledge. The medieval period was focused more on theology. The Renaissance period saw a renewed interest in Ancient Greek philosophy and the emergence of humanism. The modern period was characterized by an increased focus on how philosophical and scientific knowledge is created. Its new ideas were used during the Enlightenment period to challenge traditional authorities. Influential developments in the 19th and 20th centuries included German idealism, pragmatism, positivism, formal logic, linguistic analysis, phenomenology, existentialism, and postmodernism.

Proclus Lycius (/ˈprɒkləs laɪˈsiːəs/; 8 February 412 – 17 April 485), called Proclus the Successor (Ancient Greek: Πρόκλος ὁ Διάδοχος, Próklos ho Diádokhos), was a Greek Neoplatonist philosopher, one of the last major classical philosophers of late antiquity. He set forth one of the most elaborate and fully developed systems of Neoplatonism and, through later interpreters and translators, exerted an influence on Byzantine philosophy, early Islamic philosophy, scholastic philosophy, and German idealism, especially G. W. F. Hegel, who called Proclus's Platonic Theology "the true turning point or transition from ancient to modern times, from ancient philosophy to Christianity."

Continental philosophy is a group of Western philosophies first prominent in 20th-century continental Europe that derive from a broadly Kantian tradition of focusing on the individual and society. Continental philosophy includes German idealism, phenomenology, philosophical pessimism, existentialism (and its antecedents, such as the thought of Kierkegaard and Nietzsche), hermeneutics, structuralism, post-structuralism, deconstruction, French feminism, psychoanalytic theory, posthumanism, speculative realism, and the critical theory of the Frankfurt School as well as some Freudian, Hegelian, and Western Marxist views.

There is no academic consensus on the definition of continental philosophy. Prior to the twentieth century, the term "continental" was used broadly to refer to philosophy from continental Europe. A slightly narrower use of the term originated among English-speaking philosophers since the second half of the 20th century, who use it as a convenient catch-all term to refer to a range of thinkers and traditions outside the movement known as analytic philosophy. The term continental philosophy may mark merely a family resemblance across disparate philosophical views; a similar argument has been made for analytic philosophy.
