Question: What city is the person who broadened the doctrine of philosophy of language from?

full_context: Document 1: Philosophy of mind: In Western Philosophy, the earliest discussions of dualist ideas are in the writings of Plato who maintained that humans' ``intelligence ''(a faculty of the mind or soul) could not be identified with, or explained in terms of, their physical body. However, the best - known version of dualism is due to René Descartes (1641), and holds that the mind is a non-extended, non-physical substance, a`` res cogitans''. Descartes was the first to clearly identify the mind with consciousness and self - awareness, and to distinguish this from the brain, which was the seat of intelligence. He was therefore the first to formulate the mind -- body problem in the form in which it still exists today.
Document 2: Empiricism: The neopositivists subscribed to a notion of philosophy as the conceptual clarification of the methods, insights and discoveries of the sciences. They saw in the logical symbolism elaborated by Frege (1848–1925) and Bertrand Russell (1872–1970) a powerful instrument that could rationally reconstruct all scientific discourse into an ideal, logically perfect, language that would be free of the ambiguities and deformations of natural language. This gave rise to what they saw as metaphysical pseudoproblems and other conceptual confusions. By combining Frege's thesis that all mathematical truths are logical with the early Wittgenstein's idea that all logical truths are mere linguistic tautologies, they arrived at a twofold classification of all propositions: the analytic (a priori) and the synthetic (a posteriori). On this basis, they formulated a strong principle of demarcation between sentences that have sense and those that do not: the so-called verification principle. Any sentence that is not purely logical, or is unverifiable is devoid of meaning. As a result, most metaphysical, ethical, aesthetic and other traditional philosophical problems came to be considered pseudoproblems.
Document 3: Heinrich Mann: Born in Lübeck, as the oldest child of Senator Thomas Johann Heinrich Mann, grain merchant and finance minister of the Free City of Lübeck, a state of the German Empire, and Júlia da Silva Bruhns. He was the elder brother of novelist Thomas Mann. The Mann family was an affluent family of grain merchants of the Hanseatic city of Lübeck. After the death of his father, his mother relocated the family to Munich, where Heinrich began his career as a "freier Schriftsteller" (free novelist).
Document 4: Marte Michelet: She is the daughter of novelist and politician Jon Michelet and Toril Brekke. They resided in Lindeberg, Oslo before her parents split up. Marte Michelet moved into an apartment in Oslo, that once had housed a young Jewish girl who was deported to Auschwitz.
Document 5: Avicenna: Ibn Sīnā wrote extensively on early Islamic philosophy, especially the subjects logic, ethics, and metaphysics, including treatises named Logic and Metaphysics. Most of his works were written in Arabic – then the language of science in the Middle East – and some in Persian. Of linguistic significance even to this day are a few books that he wrote in nearly pure Persian language (particularly the Danishnamah-yi 'Ala', Philosophy for Ala' ad-Dawla'). Ibn Sīnā's commentaries on Aristotle often criticized the philosopher,[citation needed] encouraging a lively debate in the spirit of ijtihad.
Document 6: Idealism: and proliferation of hyphenated entities such as "thing-in-itself" (Immanuel Kant), "things-as-interacted-by-us" (Arthur Fine), "table-of-commonsense" and "table-of-physics" (Sir Arthur Eddington) which are "warning signs" for conceptual idealism according to Musgrave because they allegedly do not exist but only highlight the numerous ways in which people come to know the world. This argument does not take into account the issues pertaining to hermeneutics, especially at the backdrop of analytic philosophy. Musgrave criticized Richard Rorty and Postmodernist philosophy in general for confusion of use and mention.
Document 7: Thomas Mann: Paul Thomas Mann was born to a bourgeois family in Lübeck, the second son of Thomas Johann Heinrich Mann (a senator and a grain merchant) and his wife Júlia da Silva Bruhns, a Brazilian woman of German and Portuguese ancestry, who emigrated to Germany with her family when she was seven years old. His mother was Roman Catholic but Mann was baptised into his father's Lutheran religion. Mann's father died in 1891, and after that his trading firm was liquidated. The family subsequently moved to Munich. Mann first studied science at a Lübeck "gymnasium" (secondary school), then attended the Ludwig Maximillians University of Munich as well as the Technical University of Munich, where, in preparation for a journalism career, he studied history, economics, art history and literature.
Document 8: Idealism: A major concern of Hegel's Phenomenology of Spirit (1807) and of the philosophy of Spirit that he lays out in his Encyclopedia of the Philosophical Sciences (1817–1830) is the interrelation between individual humans, which he conceives in terms of "mutual recognition." However, what Climacus means by the aforementioned statement, is that Hegel, in the Philosophy of Right, believed the best solution was to surrender one's individuality to the customs of the State, identifying right and wrong in view of the prevailing bourgeois morality. Individual human will ought, at the State's highest level of development, to properly coincide with the will of the State. Climacus rejects Hegel's suppression of individuality by pointing out it is impossible to create a valid set of rules or system in any society which can adequately describe existence for any one individual. Submitting one's will to the State denies personal freedom, choice, and responsibility.
Document 9: Idealism: Beginning with Immanuel Kant, German idealists such as G. W. F. Hegel, Johann Gottlieb Fichte, Friedrich Wilhelm Joseph Schelling, and Arthur Schopenhauer dominated 19th-century philosophy. This tradition, which emphasized the mental or "ideal" character of all phenomena, gave birth to idealistic and subjectivist schools ranging from British idealism to phenomenalism to existentialism. The historical influence of this branch of idealism remains central even to the schools that rejected its metaphysical assumptions, such as Marxism, pragmatism and positivism.
Document 10: Thomas Thaarup: Thomas Thaarup was born in Copenhagen, where his father, Niels Thaarup, owned a hardware store. His mother's name was Anna Margaretha and her maiden name was Stupsack.
Document 11: Søren Kierkegaard: Kierkegaard was born to an affluent family in Copenhagen. His mother, Ane Sørensdatter Lund Kierkegaard, had served as a maid in the household before marrying his father, Michael Pedersen Kierkegaard. She was an unassuming figure: quiet, plain, and not formally educated, but Henriette Lund, her granddaughter, wrote that she "wielded the sceptre with joy and protected [Søren and Peter] like a hen protecting her chicks". She also wielded influence on her children so that later Peter said that his brother preserved many of their mother's words in his writings. His father, on the other hand, was a well-to-do wool merchant from Jutland. He was a "very stern man, to all appearances dry and prosaic, but under his 'rustic cloak' demeanor he concealed an active imagination which not even his great age could blunt". He was also interested in philosophy and often hosted intellectuals at his home. The young Kierkegaard read the philosophy of Christian Wolff. He also preferred the comedies of Ludvig Holberg, the writings of Georg Johann Hamann, Gotthold Ephraim Lessing, Edward Young, and Plato, especially those referring to Socrates.
Document 12: Bodil Koch: Bodil Koch graduated from the University of Copenhagen with a master's degree in theology in 1929, the same year she married Hal Koch. Their fundamental beliefs combined the Evangelical-Lutheran view of Christianity with Socratic humanism. Both had a strong interest in traveling and science and working for the common good. They were the icons of a whole generation after World War II searching for a new set of values. They had five children, and during the 1930s Bodil Koch was a stay-at-home mother and the wife of Hal Koch. They challenged the traditional idea of the nuclear family, and eventually she saw the ideal family as two working adults and a number of children who all participated in cooking and debating.
Document 13: Margaret Mead: Margaret Mead, the first of five children, was born in Philadelphia, but raised in nearby Doylestown, Pennsylvania. Her father, Edward Sherwood Mead, was a professor of finance at the Wharton School of the University of Pennsylvania, and her mother, Emily (née Fogg) Mead, was a sociologist who studied Italian immigrants. Her sister Katharine (1906–1907) died at the age of nine months. This was a traumatic event for Mead, who had named the girl, and thoughts of her lost sister permeated her daydreams for many years. Her family moved frequently, so her early education was directed by her grandmother until, at age 11, she was enrolled by her family at Buckingham Friends School in Lahaska, Pennsylvania. Her family owned the Longland farm from 1912 to 1926. Born into a family of various religious outlooks, she searched for a form of religion that gave an expression of the faith that she had been formally acquainted with, Christianity. In doing so, she found the rituals of the Episcopal Church to fit the expression of religion she was seeking. Mead studied one year, 1919, at DePauw University, then transferred to Barnard College where she found anthropology mired in "the stupid underbrush of nineteenth century arguments."
Document 14: Philosophy of language: In the early 19th century, the Danish philosopher Søren Kierkegaard insisted that language ought to play a larger role in Western philosophy. He argues that philosophy has not sufficiently focused on the role language plays in cognition and that future philosophy ought to proceed with a conscious focus on language:
Document 15: Katti Anker Møller: She was born Cathrine Anker in Hamar, the daughter of Herman Anker. She had nine siblings and grew up around the first folk high school at Sagatun in Hamar, which was founded by her father. Educated as a teacher, she spent a year in France, where her exposure to the life of prostitutes and single mothers affected her profoundly. Her mother died at the age of 50, apparently exhausted from her many pregnancies though the number of children she had was normal for her time.
