Nelson subsequently became influential in both philosophy and mathematics, as his close contacts with scientists and mathematicians influenced their ideas. Despite dying earlier than many of his friends and assistants, his ISK organization lived on after his death, even after being banned by the Nazi Regime in 1933. It is even claimed that Albert Einstein supported it.[3] He's also credited with popularizing the Socratic method in his book Die sokratische Methode (The Socratic Method).[4]
Life
Early life and education
Leonard Nelson was the son of lawyer Heinrich Nelson (1854–1929) and artist Elisabeth Lejeune Dirichlet (1860–1920).[5] His mother was the granddaughter of mathematician Peter Gustav Lejeune Dirichlet and descendant of Jewish philosopher Moses Mendelssohn.[6] Nelson was baptised as a Protestant at the age of five on 13 June 1887.[7]
Nelson's work as a philosopher was most concerned with critical philosophy, attributed to Kant. It sets out to find a "critique" on science and metaphysics, similar to empiricism,[8] as things can only be true based on the perceptions and limitations on human minds. Kant's 1781 book Critique of Pure Reason (Kritik der reinen Vernunft) inspired Nelson to go down the path of critical philosophy, and later followed the works of post-Kantian philosopher Fries who had also followed Kant's work.[9]
His first dissertation was Die kritische Methode und das Verhältnis der Psychologie zur Philosophie (The Critical Method and the Relationship of Psychology to Philosophy), which failed. His 1904 dissertation Jakob Fries and his Latest Critics (Jakob Friedrich Fries und seine jüngsten Kritiker) was successful. Nelson continued defending Fries' philosophy and ideas by publishing a neue Folge (new series) of Abhandlungen der Fries'schen Schule (1904) with Gerhard Hessenberg and mathematician Karl Kaiser. It was here that Nelson and these same friends created the Jakob-Friedrich-Fries-Gesellschaft (Jakob Friedrich Fries Society) to promote critical philosophy.[9]
In 1922, Nelson founded the Philosophisch-Politische Akademie (Philosophical-Political Academy or PPA) as a "Platonic Academy" and non-profit association, which was abandoned soon after the Nazis banned it, but re-established in 1949. It still stands today for political discussions between philosophers and politicians,[12] and was supported financially by the Gesellschaft der Freunde der Philosophisch-Politischen Akademie (Society of Friends of the Philosophical-Political Academy or GFA).[13] They started working with an education center called Landerziehungsheim Walkemühle, founded in 1921 by a support of Nelson, progressive teacher Ludwig Wunder (1878–1949). Although Wunder left it shortly after in 1924, educator and co-worker of Nelson, Minna Specht, took over,[14] with the help of journalist and author Mary Saran.
Internationaler Sozialistischer Kampfbund (ISK)
In 1917 Nelson and Minna Specht founded the Internationaler Jugendbund (International Youth Federation or IJB). In 1918, Nelson briefly became a member of the Independent Social Democratic Party (USPD), and from 1923–1925 he was a member of the Social Democratic Party (SPD), until he was ultimately excluded. As a result, in 1925, he and Minna Specht founded the Internationaler Sozialistischer Kampfbund(ISK; "International Socialist Militant League") merging it with the IJB by taking over its publishing label, Öffentliches Leben.[10] Among Leonard Nelson's students and political companions in the International Socialist Kampfbund were also[15]Prime MinisterAlfred Kubel (1909–1999) and journalist Fritz Eberhard (1896–1982), later member of the Parlamentarischer Rat.
Nelson married Elisabeth Schemmann (1884–1954), in 1907, but divorced in 1912 after she baptised their son Gerhard David Wilhelm Nelson (1909–1944) in the Lutheran Church. Nelson's refusal to baptise his son and divorce was a big change based on his Jewish ancestry. He even resigned from the Evangelical Church in 1919.[16]
Nelson was an early advocate of animal rights and a vegetarian.[18] His lecture "Duties to Animals" was published posthumously in Germany in 1932 and included in his book A System of Ethics (translated in 1956) and reprinted in the 1972 book Animals, Men and Morals.[19]
Nelson was an insomniac and died at a young age from pneumonia, and was buried at a Jewish cemetery in Melsungen alongside his father Heinrich.[20]
Posthumous legacy
In the summer of 1997 his granddaughter, Maria Nelson, and Maria's daughter, Rachel Urban, both visited his grave .[20]
Nelson's ideas continued to have an impact upon German socialism and communism in Nazi Germany as the ISK's members became active in the left-wing resistance to Nazism.[citation needed]
Bibliography
Nelson published numerous books and papers, often with the help of other philosophers and mathematicians. He was later critical of Georg Wilhelm Friedrich Hegel in his work Progress and Regress in Philosophy (Fortschritte und Rückschritte der Philosophie). He is also known for defending the idea of animal rights in his work System of Philosophical Ethics and Pedagogy (System der philosophischen Ethik und Pädagogik) published in 1932, with the help of his assistant Grete Hermann (also part of the ISK) and Minna Specht.[21]
