Georg Wilhelm Friedrich Hegel

Georg Wilhelm Friedrich Hegel The birthplace of Hegel in Stuttgart, which now houses The Hegel Museum Georg Wilhelm Friedrich Hegel (German: [ˈɡeɔɐ̯k ˈvɪlhɛlm ˈfʁiːdʁɪç ˈheːɡəl]; August 27, 1770 – November 14, 1831) was a German philosopher, and a major figure in German Idealism. His historicist and idealist account of reality revolutionized European philosophy and was an important precursor to Continental philosophy and Marxism. Hegel developed a comprehensive philosophical framework, or "system", of Absolute idealism to account in an integrated and developmental way for the relation of mind and nature, the subject and object of knowledge, psychology, the state, history, art, religion, and philosophy. In particular, he developed the concept that mind or spirit manifested itself in a set of contradictions and oppositions that it ultimately integrated and united, without eliminating either pole or reducing one to the other.
John Locke

John Locke

John Locke FRS (/ˈlɒk/; 29 August 1632 – 28 October 1704), widely known as the Father of Classical Liberalism,[2][3][4] was an English philosopher and physician regarded as one of the most influential of Enlightenment thinkers. Considered one of the first of the British empiricists, following the tradition of Francis Bacon, he is equally important to social contract theory. His work greatly affected the development of epistemology and political philosophy. His writings influenced Voltaire and Rousseau, many Scottish Enlightenment thinkers, as well as the American revolutionaries. His contributions to classical republicanism and liberal theory are reflected in the United States Declaration of Independence.[5] Biography

Bertrand Arthur William Russell, 3rd Earl Russell, OM, FRS[45] (18 May 1872 – 2 February 1970) was a British nobleman, philosopher, logician, mathematician, historian, and social critic.[46] 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.[47] He was born in Monmouthshire, into one of the most prominent aristocratic families in Britain.[48] Russell led the British "revolt against idealism" in the early 20th century.[49] He is considered one of the founders of analytic philosophy along with his predecessor Gottlob Frege and his protégé Ludwig Wittgenstein. He is widely held to be one of the 20th century's premier logicians.[46] He co-authored, with A.

Karl Wilhelm Friedrich Schlegel Friedrich Schlegel in 1801 Karl Wilhelm Friedrich (after 1814: von) Schlegel (10 March 1772 – 12 January 1829) was a German poet, literary critic, philosopher, philologist and indologist. With his older brother, August Wilhelm Schlegel, he was one of the main figures of the Jena romantics. He was a zealous promotor of the Romantic movement and inspired Samuel Taylor Coleridge, Adam Mickiewicz and Kazimierz Brodziński. Schlegel was a pioneer in Indo-European studies, comparative linguistics, in what became known as Grimm's law, and morphological typology. As a young man he was an atheist, a radical, and an individualist. Karl Wilhelm Friedrich Schlegel
John Stuart Mill John Stuart Mill, FRSE (20 May 1806 – 8 May 1873) was an English philosopher, political economist and civil servant. He was an influential contributor to social theory, political theory and political economy. He has been called "the most influential English-speaking philosopher of the nineteenth century".[3] Mill's conception of liberty justified the freedom of the individual in opposition to unlimited state control.[4] He was a proponent of utilitarianism, an ethical theory developed by Jeremy Bentham. Hoping to remedy the problems found in an inductive approach to science, such as confirmation bias, he clearly set forth the premises of falsifiability as the key component in the scientific method.[5] Mill was also a Member of Parliament and an important figure in liberal political philosophy.

René Descartes

René Descartes

Descartes frequently sets his views apart from those of his predecessors. In the opening section of the Passions of the Soul, a treatise on the early modern version of what are now commonly called emotions, Descartes goes so far as to assert that he will write on this topic "as if no one had written on these matters before". Many elements of his philosophy have precedents in late Aristotelianism, the revived Stoicism of the 16th century, or in earlier philosophers like Augustine. In his natural philosophy, he differs from the schools on two major points: First, he rejects the splitting of corporeal substance into matter and form; second, he rejects any appeal to final ends—divine or natural—in explaining natural phenomena.[8] In his theology, he insists on the absolute freedom of God's act of creation.
Thomas Hobbes Hobbes was a champion of absolutism for the sovereign, but he also developed some of the fundamentals of European liberal thought: the right of the individual; the natural equality of all men; the artificial character of the political order (which led to the later distinction between civil society and the state); the view that all legitimate political power must be "representative" and based on the consent of the people; and a liberal interpretation of law which leaves people free to do whatever the law does not explicitly forbid.[3] He was one of the founders of modern political philosophy and political science.[4][5] His understanding of humans as being matter and motion, obeying the same physical laws as other matter and motion, remains influential; and his account of human nature as self-interested cooperation, and of political communities as being based upon a "social contract" remains one of the major topics of political philosophy.

Friedrich Wilhelm Nietzsche (/ˈniːtʃə/[42] or /ˈnitʃi/;[43] German: [ˈfʁiːdʁɪç ˈvɪlhɛlm ˈniːt͡sʃə]; 15 October 1844 – 25 August 1900) was a German philologist, philosopher, cultural critic, poet and composer. He wrote several critical texts on religion, morality, contemporary culture, philosophy and science, displaying a fondness for metaphor, irony and aphorism. Nietzsche's key ideas include the Apollonian/Dionysian dichotomy, perspectivism, the Will to Power, the "death of God", the Übermensch and eternal recurrence.

Karl Marx

Karl Heinrich Marx (German pronunciation: [kaːɐ̯l ˈhaɪnʀɪç ˈmaːɐ̯ks], 5 May 1818 – 14 March 1883) was a German philosopher, economist, sociologist, historian, journalist, and revolutionary socialist. Marx's work in economics laid the basis for the current understanding of labour and its relation to capital, and has influenced much of subsequent economic thought.[4][5][6][7] He published numerous books during his lifetime, the most notable being The Communist Manifesto (1848) and Das Kapital (1867–1894). Born into a wealthy middle-class family in Trier in the Prussian Rhineland, Marx studied at the University of Bonn and the University of Berlin, where he became interested in the philosophical ideas of the Young Hegelians. After his studies, he wrote for a radical newspaper in Cologne, and began to work out his theory of dialectical materialism.

Ludwig Josef Johann Wittgenstein (26 April 1889 – 29 April 1951) was an Austrian-British philosopher who worked primarily in logic, the philosophy of mathematics, the philosophy of mind, and the philosophy of language.[4] From 1939–1947, Wittgenstein taught at the University of Cambridge.[5] During his lifetime he published just one slim book, the 75-page Tractatus Logico-Philosophicus (1921), one article, one book review and a children's dictionary.[6] His voluminous manuscripts were edited and published posthumously. Philosophical Investigations appeared as a book in 1953 and by the end of the century it was considered an important modern classic.[7] Philosopher Bertrand Russell described Wittgenstein as "the most perfect example I have ever known of genius as traditionally conceived; passionate, profound, intense, and dominating".[8] Born in Vienna into one of Europe's richest families, he inherited a large fortune from his father in 1913.

Immanuel Kant

Immanuel Kant (German: [ɪˈmaːnu̯eːl kant]; 22 April 1724 – 12 February 1804) was a German philosopher who is widely considered to be a central figure of modern philosophy. He argued that human concepts and categories structure our view of the world and its laws, and that reason is the source of morality. His thought continues to hold a major influence in contemporary thought, especially in fields such as metaphysics, epistemology, ethics, political philosophy, and aesthetics.[1] Kant's major work, the Critique of Pure Reason (Kritik der reinen Vernunft, 1781),[2] aimed to bring reason together with experience and to move beyond what he took to be failures of traditional philosophy and metaphysics. He hoped to end an age of speculation where objects outside experience were seen to support what he saw as futile theories, while resisting the skepticism of thinkers such as David Hume.
Martin Heidegger (German: [ˈmaɐ̯tiːn ˈhaɪdɛɡɐ]; September 26, 1889 – May 26, 1976) was a German philosopher known for his existential and phenomenological explorations of the "question of Being".[6] Heidegger is known for offering a phenomenological critique of Kant. He wrote extensively on Nietzsche and Hölderlin in his later career. Heidegger's influence has been far reaching, influencing fields such as philosophy, theology, art, architecture, artificial intelligence, cultural anthropology, design, literary theory, social theory, political theory, psychiatry, and psychotherapy.[7][8] His best known book, Being and Time, is considered one of the most important philosophical works of the 20th century.[9] In it and later works, Heidegger maintained that our way of questioning defines our nature. He argued that philosophy, Western civilization's chief way of questioning, had lost sight of the being it sought.
