Philosophy academics

Roland Gérard Barthes (; French: [ʁɔlɑ̃ baʁt]; 12 November 1915 – 26 March 1980) was a French literary theorist, essayist, philosopher, critic, and semiotician. His work engaged in the analysis of a variety of sign systems, mainly derived from Western popular culture. His ideas explored a diverse range of fields and influenced the development of many schools of theory, including structuralism, anthropology, literary theory, and post-structuralism.
Barthes is perhaps best known for his 1957 essay collection Mythologies, which contained reflections on popular culture, and the 1967/1968 essay "The Death of the Author," which critiqued traditional approaches in literary criticism. During his academic career he was primarily associated with the École des Hautes Études en Sciences Sociales (EHESS) and the Collège de France.

Moritz Geiger (26 June 1880 – 9 September 1937) was a German philosopher and a disciple of Edmund Husserl. He was a member of the Munich phenomenological school. Beside phenomenology, he dedicated himself to psychology, epistemology and aesthetics.

Gerardus Johannes Petrus Josephus Bolland (9 June 1854, Groningen – 11 February 1922, Leiden), also known as G.J.P.J. Bolland, was a Dutch autodidact, linguist, philosopher, biblical scholar, and lecturer. An excellent orator, he gave extremely well attended public lectures in Amsterdam, Rotterdam, The Hague, Utrecht, Delft, Groningen, Nijmegen and Belgium.
He became an expert in German idealism, being especially interested in the works of Eduard von Hartmann and Georg Wilhelm Friedrich Hegel. He began researching the formation of Christianity in 1891, and was extremely literate in religious history. He was associated with the Dutch radical school.
He effected a revival in Hegelianism in the Netherlands around 1900 by arranging a new edition of Hegel’s works, and stimulating a renewal of interest in philosophy in the Netherlands. He had a quirky style in his use of the Dutch language causing linguist J.A. Dèr Mouw, among others, to criticise him sharply.

John Anderson (1 November 1893 – 6 July 1962) was a Scottish philosopher who occupied the post of Challis Professor of Philosophy at Sydney University from 1927 to 1958. He founded the empirical brand of philosophy known as Australian realism.
Anderson's promotion of 'freethought' in all subjects, including politics and morality, was controversial and brought him into constant conflict with the august senate of the university. However, he is credited with educating a generation of influential 'Andersonian' thinkers and activists—some of whom helped to place Sydney in the forefront of the 'sexual revolution' of the 1950s and 1960s.
To Anderson, an acceptable philosophy must have significant 'sweep' and be capable of challenging and moulding ideas in every aspect of intellect and society.

Pierre Hadot (; French: [ado]; 21 February 1922 – 24 April 2010) was a French philosopher and historian of philosophy specializing in ancient philosophy, particularly Epicureanism and Stoicism.

Jean-Gaspard-Félix Laché Ravaisson-Mollien (French: [ʁavɛsɔ̃ mɔljɛ̃]; 23 October 1813 – 18 May 1900) was a French philosopher, 'perhaps France's most influential philosopher in the second half of the nineteenth century'. He was originally and remains more commonly known as Félix Ravaisson.His 'seminal' 'key' work was De l’habitude (1838), translated in English as Of Habit. Ravaisson's philosophy is in the tradition of French Spiritualism, which was initiated by Pierre Maine de Biran (1766–1824) with the essay "The Influence of Habit on the Faculty of Thinking" (1802). However, Ravaisson developed his doctrine as what he called 'spiritualist realism' and 'spiritualist positivism', and – according to Ravaisson scholar Mark Sinclair – can be thought of as founding 'the school of contingency'. His most well known and influential successor was Henri Bergson, with whom the tradition can be seen to end during the 1930s; although the 'lineage' of this 'philosophy of life' can be seen to return in the late twentieth century with Gilles Deleuze. Ravaisson never worked in the French state university system, in his late 20s declining a position at the University of Rennes. In 1838 he was employed as the principle private secretary to the Minister of Public Instruction, going on to secure high-ranking positions such as Inspector General of Libraries, and then the Curator of Classical Antiquities at the Louvre. Later in his life he was appointed as the President of the Jury of the Aggregation of philosophy in France, 'a position of considerable influence'. Ravaisson, was not only a philosopher, classicist, archivist, and educational administrator, but also a painter exhibiting under the name Laché.

Jean-Marie Guyau (28 October 1854 – 31 March 1888) was a French philosopher and poet.
Guyau was inspired by the philosophies of Epicurus, Epictetus, Plato, Immanuel Kant, Herbert Spencer, and Alfred Fouillée, and the poetry and literature of Pierre Corneille, Victor Hugo, and Alfred de Musset.

Etienne Vermeersch (2 May 1934, Sint-Michiels, Bruges – 18 January 2019, Ghent) was a Belgian moral philosopher, skeptic, opinion maker and debater. He is one of the founding fathers of the abortion, euthanasia law, and the Law on Patients' Rights in Belgium. Vermeersch became an atheist after five years with the Society of Jesus (Jesuits). Later he became a philosophical materialist. In January 2008, Vermeersch was chosen by hundred prominent Flemings as the most influential intellectual of Flanders. He died in a hospital in Ghent on 18 January 2019 by euthanasia after a long illness.

Eduard Gottlob Zeller (German: [ˈtsɛlɐ]; 22 January 1814, Kleinbottwar – 19 March 1908, Stuttgart) was a German philosopher and Protestant theologian of the Tübingen School of theology. He was well known for his writings on Ancient Greek philosophy, especially Pre-Socratic Philosophy, and most of all for his celebrated, multi-volume historical treatise The Philosophy of Greeks in their Historical Development (1844–52). Zeller was also a central figure in the revival of neo-Kantianism.
