Ludwig Wittgenstein 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.

G. E. Moore Life and work[edit] Moore was born in South London on 4 November 1873.[2] His eldest brother was Thomas Sturge Moore, a poet, writer and engraver.[3] In 1892, he was educated at Dulwich College[4] and then attended Trinity College Cambridge to study classics for moral sciences.[5] He became a Fellow of Trinity in 1898, and went on to hold the University of Cambridge chair of mental philosophy and logic, from 1925 to 1939. Moore is best known today for his defence of ethical non-naturalism, his emphasis on common sense in philosophical method, and the paradox that bears his name. G. E. Moore
Russell led the British "revolt against idealism" in the early 20th century.[58] He is considered one of the founders of analytic philosophy along with his predecessor Gottlob Frege, colleague G. E. Moore, and his protégé Ludwig Wittgenstein.

Analytic philosophy Analytic philosophy (sometimes analytical philosophy) is a style of philosophy that came to dominate English-speaking countries in the 20th century. In the United Kingdom, United States, Canada, Scandinavia, Australia, and New Zealand, the vast majority of university philosophy departments identify themselves as "analytic" departments.[1] The term "analytic philosophy" can refer to:

José Guilherme Merquior José Guilherme Merquior José Guilherme Merquior (April 22, 1941 – January 7, 1991) was a Brazilian diplomat, academic, writer, literary critic and philosopher. Biography[edit] He was a prolific writer, and member of the Academia Brasileira de Letras (the Brazilian Academy of Letters). He had a doctorate in sociology from the London School of Economics, which was directed by Ernest Gellner.
He was awarded the 1927 Nobel Prize in Literature "in recognition of his rich and vitalizing ideas and the brilliant skill with which they have been presented".[2] In 1930, France awarded him its highest honour, the Grand-Croix de la Legion d'honneur. Biography[edit] Overview[edit] Bergson was born in the Rue Lamartine in Paris, not far from the Palais Garnier (the old Paris opera house) in 1859. His father, the pianist Michał Bergson, was of a Polish Jewish family background (originally bearing the name Bereksohn). His mother, Katherine Levison, daughter of a Yorkshire doctor, was from an English and Irish Jewish background. Henri Bergson Henri Bergson
Gottlob Frege Gottlob Frege Friedrich Ludwig Gottlob Frege (German: [ˈɡɔtloːp ˈfreːɡə]; 8 November 1848 – 26 July 1925) was a German mathematician, logician and philosopher. He is considered to be one of the founders of modern logic and made major contributions to the foundations of mathematics. He is generally considered to be the father of analytic philosophy, for his writings on the philosophy of language and mathematics. While he was mainly ignored by the intellectual world when he published his writings, Giuseppe Peano (1858–1932) and Bertrand Russell (1872–1970) introduced his work to later generations of logicians and philosophers.

Friedrich Heinrich Jacobi Friedrich Heinrich Jacobi (25 January 1743 – 10 March 1819) was an influential German philosopher, literary figure, socialite, and the younger brother of poet Johann Georg Jacobi. He is notable for coining the term nihilism and promoting it as the prime fault of Enlightenment thought particularly in the philosophical systems of Baruch Spinoza, Immanuel Kant, Johann Fichte and Friedrich Schelling.[1] Instead of speculative reason, he advocated Glaube (variously translated as faith or "belief") and revelation. In this sense, Jacobi anticipated present-day writers who criticize secular philosophy as relativistic and dangerous for religious faith. Friedrich Heinrich Jacobi
Karl Leonhard Reinhold Karl Leonhard Reinhold Karl Leonhard Reinhold (26 October 1757 – 10 April 1823) was an Austrian philosopher. He was the father of Ernst Reinhold, also a philosopher. Life[edit] Reinhold was born in Vienna. At the age of fourteen he entered the Jesuit college of St.
Western philosophy Origins[edit] The scope of philosophy in the ancient understanding, and the writings of (at least some of) the ancient philosophers, were all intellectual endeavors. This included the problems of philosophy as they are understood today; but it also included many other disciplines, such as pure mathematics and natural sciences such as physics, astronomy, and biology (Aristotle, for example, wrote on all of these topics.) The term "Western philosophy" is at times unhelpful and vague, since the definition involves a vast variety of distinct traditions, political groups, religious groups, and individual writers over thousands of years.

Heraclitus of Ephesus (/ˌhɛrəˈklaɪtəs/;[1] Greek: Ἡράκλειτος ὁ Ἐφέσιος, Hērákleitos ho Ephésios; c. 535 – c. 475 BCE) was a pre-Socratic Greek philosopher, a native of the Greek city Ephesus, Ionia, on the coast of Asia Minor. He was of distinguished parentage. Little is known about his early life and education, but he regarded himself as self-taught and a pioneer of wisdom.


Parmenides of Elea (/pɑrˈmɛnɨdiːz əv ˈɛliə/; Ancient Greek: Παρμενίδης ὁ Ἐλεάτης; fl. 5th century BCE) was an ancient Greek philosopher born in Elea, a Greek city on the southern coast of Magna Graecia. He was the founder of the Eleatic school of philosophy. The single known work of Parmenides is a poem, On Nature, which has survived only in fragmentary form. In this poem, Parmenides describes two views of reality.

Edmund Husserl

Although born into a Jewish family, Husserl was baptized as a Lutheran in 1886. He studied mathematics under Karl Weierstrass and Leo Königsberger, and philosophy under Franz Brentano and Carl Stumpf. Husserl himself taught philosophy as a Privatdozent at Halle from 1887, then as professor, first at Göttingen from 1901, then at Freiburg from 1916 until he retired in 1928. Thereafter he gave two notable lectures: at Paris in 1929, and at Prague in 1935.
In Göttingen, he advised his student Arthur Schopenhauer to concentrate on the philosophies of Plato and Kant. This advice had a strong influence on Schopenhauer's philosophy. In the winter semester of 1810 and 1811, Schopenhauer studied both psychology and metaphysics under Schulze.[2] Gottlob Ernst Schulze
