Question: Immanuel Kant (; German: [I'ma:nue:l kant]; 22 April 1724 - 12 February 1804) was a German philosopher who is a central figure in modern philosophy. Kant argues that the human mind creates the structure of human experience, that reason is the source of morality, that aesthetics arises from a faculty of disinterested judgment, that space and time are forms of human sensibility, and that the world as it is "in-itself" is independent of humanity's concepts of it. Kant took himself to have effected a "Copernican revolution" in philosophy, akin to Copernicus' reversal of the age-old belief that the sun revolves around the earth.

In "Perpetual Peace: A Philosophical Sketch", Kant listed several conditions that he thought necessary for ending wars and creating a lasting peace. They included a world of constitutional republics. His classical republican theory was extended in the Science of Right, the first part of the Metaphysics of Morals (1797). Kant believed that universal history leads to the ultimate world of republican states at peace, but his theory was not pragmatic. The process was described in "Perpetual Peace" as natural rather than rational:  The guarantee of perpetual peace is nothing less than that great artist, nature...In her mechanical course we see that her aim is to produce a harmony among men, against their will, and indeed through their discord. As a necessity working according to laws we do not know, we call it destiny. But, considering its designs in universal history, we call it "providence," inasmuch as we discern in it the profound wisdom of a higher cause which predetermines the course of nature and directs it to the objective final end of the human race.  Kant's political thought can be summarized as republican government and international organization. "In more characteristically Kantian terms, it is doctrine of the state based upon the law (Rechtsstaat) and of eternal peace. Indeed, in each of these formulations, both terms express the same idea: that of legal constitution or of 'peace through law'. Taken simply by itself, Kant's political philosophy, being essentially a legal doctrine, rejects by definition the opposition between moral education and the play of passions as alternate foundations for social life. The state is defined as the union of men under law. The state rightly so called is constituted by laws which are necessary a priori because they flow from the very concept of law. A regime can be judged by no other criteria nor be assigned any other functions, than those proper to the lawful order as such."  He opposed "democracy," which at his time meant direct democracy, believing that majority rule posed a threat to individual liberty. He stated, "...democracy is, properly speaking, necessarily a despotism, because it establishes an executive power in which 'all' decide for or even against one who does not agree; that is, 'all,' who are not quite all, decide, and this is a contradiction of the general will with itself and with freedom." As with most writers at the time, he distinguished three forms of government i.e. democracy, aristocracy, and monarchy with mixed government as the most ideal form of it.

Problem: Daniel Barenboim (born 15 November 1942) is an Argentine-Israeli pianist and conductor who is a citizen of Argentina, Israel, Palestine, and Spain. He is the general music director of the Berlin State Opera, and the Staatskapelle Berlin; he previously served as Music Director of the Chicago Symphony Orchestra, the Orchestre de Paris and La Scala in Milan. Barenboim is known for his work with the West-Eastern Divan Orchestra, a Seville-based orchestra of young Arab and Israeli musicians, and as a resolute critic of the Israeli occupation of Palestinian territories. Barenboim has received many awards and prizes, including an honorary Knight Commander of the Order of the British Empire, France's Legion d'honneur both as a Commander and Grand Officier, and the German Grosses Bundesverdienstkreuz and Willy Brandt Award.

Daniel Barenboim was born in 1942 in Buenos Aires, Argentina, to Argentinian-Jewish parents Aida (nee Schuster) and Enrique Barenboim. He started piano lessons at the age of five with his mother, continuing to study with his father, who remained his only teacher. On 19 August 1950, at the age of seven, he gave his first formal concert in his hometown, Buenos Aires.  In 1952, Barenboim's family moved to Israel. Two years later, in the summer of 1954, his parents took him to Salzburg to take part in Igor Markevitch's conducting classes. During that summer he also met and played for Wilhelm Furtwangler, who has remained a central musical influence and ideal for Barenboim. Furtwangler called the young Barenboim a "phenomenon" and invited him to perform the Beethoven First Piano Concerto with the Berlin Philharmonic, but Barenboim's father considered it too soon after the Second World War for a child of Jewish parents to be performing in Berlin. In 1955 Barenboim studied harmony and composition with Nadia Boulanger in Paris.  On 15 June 1967, Barenboim and British cellist Jacqueline du Pre were married in Jerusalem at a Western Wall ceremony, Du Pre having converted to Judaism. Acting as one of the witnesses was the conductor Zubin Mehta, a long-time friend of Barenboim. Since "I was not Jewish I had to temporarily be renamed Moshe Cohen, which made me a 'kosher witness'," Mehta recalled. Du Pre retired from music in 1973, after being diagnosed with multiple sclerosis (MS). The marriage lasted until du Pre's death in 1987.  In the early 1980s, Barenboim began an affair with the Russian pianist Elena Bashkirova, with whom he had two sons born in Paris before du Pre's death: David Arthur, born 1983, and Michael, born 1985. Barenboim worked to keep his relationship with Bashkirova hidden from du Pre, and believed he had succeeded. He and Bashkirova married in 1988. Both sons are part of the music world: David is a manager-writer for the German hip-hop band Level 8, and Michael Barenboim is a classical violinist.
