German philosophy

They are central to major philosophical movements such as rationalism, German idealism, Romanticism, dialectical materialism, existentialism, phenomenology, hermeneutics, logical positivism, and critical theory.

The monads are "substantial forms of being" with the following properties: they are eternal, indecomposable, individual, subject to their own laws, un-interacting, and each reflecting the entire universe in a pre-established harmony (a historically important example of panpsychism).

His main achievement was a complete oeuvre on almost every scholarly subject of his time, displayed and unfolded according to his demonstrative-deductive, mathematical method, which perhaps represents the peak of Enlightenment rationality in Germany.

[10] He was invited by the Prussian king Friedrich Wilhelm IV to the post of professor at the University of Berlin with the aim of combating the then-popular ideas of the left-liberal Young Hegelians.

Hegel reveals this stage of development of the "absolute idea" in his work Philosophy of Spirit from the Encyclopedia of the Philosophical Sciences and in his lectures at the University of Berlin, many of which cover material not found in his published writings.

Schelling's aesthetics, understanding the world as an artistic creation, has adopted a universal character and served as the basis for the teachings of the Romantic school.

"[13] It is argued that Friedrich Schlegel's subjectivism and his glorification of the superior intellect as property of a select elite influenced Schelling's doctrine of intellectual intuition, which György Lukács called "the first manifestation of irrationalism".

"[17][18] In the opinion of György Lukács, Friedrich Nietzsche's importance as an irrationalist philosopher lay in that, while his early influences are to be found in Romanticism, he founded a modern irrationalism antithetical to that of the Romantics[19] Even in his post-Schopenhauerian period, however, Nietzsche paid some tributes to Romanticism, for example borrowing the title of his book The Gay Science (Die fröhliche Wissenschaft, 1882–87) from Friedrich Schlegel's 1799 novel Lucinde.

[20][21] Lukács also emphasized that the emergence of organicism in philosophy received its impetus from Romanticism: This view, that only 'organic growth', that is to say change through small and gradual reforms with the consent of the ruling class, was regarded as 'a natural principle', whereas every revolutionary upheaval received the dismissive tag of 'contrary to nature' gained a particularly extensive form in the course of the development of reactionary German romanticism (Savigny, the historical law school, etc.).

The antithesis of 'organic growth' and 'mechanical fabrication' was now elaborated: it constituted a defence of 'naturally grown' feudal privileges against the praxis of the French Revolution and the bourgeois ideologies underlying it, which were repudiated as mechanical, highbrow and abstract.

[22]Wilhelm Dilthey, founder (along with Nietzsche, Simmel, and Klages) of the intuitionist and irrationalist school of Lebensphilosophie in Germany, is credited with leading the Romantic revival in hermeneutics of the early 20th century.

They considered the representatives of art to be the happiest people, and in their works, along with knights chained in armor, poets, painters and musicians usually appear.

Schopenhauer argued that at the heart of the world and man lies the “will to life,” which leads them to suffering and boredom, and happiness can be experienced only by those who free themselves from its oppressive domination.

Hegel was hugely influential throughout the nineteenth century; by its end, according to Bertrand Russell, "the leading academic philosophers, both in America and Britain, were largely Hegelian".

And here the master’s claim was viewed as paradox, at best; the Prussian regime indeed provided extensive civil and social services, good universities, high employment and some industrialization, but it was ranked as rather backward politically compared with the more liberal constitutional monarchies of France and Britain.

[28] The Young Hegelians drew on Hegel's idea that the purpose and promise of history was the total negation of everything conducive to restricting freedom and reason; and they proceeded to mount radical critiques, first of religion and then of the Prussian political system.

Friedrich Engels, also a Young Hegelian originally, was a friend and associate of Marx, together with whom he developed the theory of scientific socialism (communism) and the doctrines of dialectical and historical materialism.

His major works include The Holy Family (together with Marx, 1844) criticizing the Young Hegelians,[29] The Condition of the Working Class in England (1845), a study of the deprived conditions of the working class in Manchester and Salford based on Engels's personal observations,[30] The Peasant War in Germany (1850), an account of the early 16th-century uprising known as the German Peasants' War with a comparison with the recent revolutionary uprisings of 1848–1849 across Europe,[31] Anti-Dühring (1878) criticizing the philosophy of Eugen Dühring, Socialism: Utopian and Scientific (1880) studying the utopian socialists Charles Fourier and Robert Owen and their differences with Engels' version of socialism,[32] Dialectics of Nature (1883) applying Marxist ideas, particularly those of dialectical materialism, to science,[33] and The Origin of the Family, Private Property and the State (1884) arguing that the family is an ever-changing institution that has been shaped by capitalism.

Joseph Dietzgen was a German leatherworker and social democrat, who independently developed a number of questions of philosophy and came to conclusions very close to the dialectical materialism of Marx and Engels.

In Russia he wrote a large philosophical treatise, The Essence of the Mental Labor of Man, a review of the first volume of Capital by Karl Marx.

In 1869 Dietzgen returned to Germany, and then moved again to America, where he wrote his philosophical works Excursions of a Socialist in the Field of the Theory of Knowledge and Acquisition of Philosophy.

The most notable “academic socialists” in Germany were Bruno Hildebrand, who was openly against Marx and Engels, Gustav von Schmoller, Adolph Wagner, Lujo Brentano, Johann Plenge, Hans Delbrück, Ferdinand Toennies and Werner Sombart.

In an age of upcoming revolutions and exciting new discoveries in science, the resigned and a-progressive nature of the typical pessimist was seen as detriment to social development.

To respond to this growing criticism, a group of philosophers greatly influenced by Schopenhauer such as Julius Bahnsen (1830–81), Karl Robert Eduard von Hartmann (1842–1906), Philipp Mainländer (1841–76), and even some of his personal acquaintances developed their own brand of pessimism, each in their own unique way.

The philosophy of Machism found support among Western European Marxists such as Friedrich Adler and Otto Bauer, and in Russia among a part of the Bolshevik intelligentsia (Alexander Bogdanov, Vladimir Bazarov, Anatoly Lunacharsky, Pavel Yushkevich, Nikolai Valentinov etc.).

The main work of Spengler, setting out his philosophy of history, The Decline of the West, was published shortly after the defeat of Imperial Germany in World War I.

His history breaks down into a number of completely independent, unique “cultures,” special organisms above and beyond, having an individual destiny and experiencing periods of emergence, flourishing and dying.

It was then transformed by Martin Heidegger (1889–1976), whose famous book Being and Time (1927) applied phenomenology to ontology, and who, along with Ludwig Wittgenstein, is considered one of the most influential philosophers of the 20th century.

No longer was it conceived of as being about understanding linguistic communication, or providing a methodological basis for the human sciences – as far as Heidegger was concerned, hermeneutics is ontology, dealing with the most fundamental conditions of man's being in the world.

In 1923, Carl Grünberg founded the Institute for Social Research, drawing from Marxism, Freud's psychoanalysis, and Weberian philosophy, which came to be known as the "Frankfurt School".
