Theodor Lorenz Haering (22 April 1884 in Stuttgart; 15 June 1964 in Tübingen) was a German philosopher, writer and philosophy professor in the University of Tübingen.
Theodor Haering was the son of the Protestant theologian and university professor Theodor von Haering and brother of the historian Hermann Haering. He initially studied Protestant theology at the University of Tübingen and passed his first theological examination in 1906. He belonged to the Tübingen Protestant Foundation and was a member of the Luginsland Tübingen student fraternity. After a short vicariate, he took a leave of absence in 1907/08 to study philosophy in Berlin. Following the 1910 doctoral dissertation at the University of Tübingen under Erich Adickes (on the Kant's Duisburg Nachlass), after further studies in Bonn (1911/12), where he was impressed by the experimental psychologist Oswald Külpe, he completed his habilitation in Tübingen, again under Erich Adickes (1912) on Die Psychologie der Wertung.
From 1919, Haering became a university lecturer in Tübingen, initially as an associate professor of philosophy. After Adicke's death in 1928, he was appointed to his chair of historical and systematic philosophy.
During the National Socialist era, Theodor Haering was a leading member of the NS-Dozentenbund; he applied for admission to the NSDAP on 23 October 1937, and was retroactively admitted on 1 May of the same year (membership number 5.896.006). He had already sympathized with the party beforehand. He understood Philosophie als geistige Rassenkunde (philosophy as an spiritual racial science, the title of a lecture from 1939) and wrote as early as 1935: "Next to the racial principle is the Führer principle. During the Second World War, he was involved in the Nazi war effort in the Geisteswissenschaften (humanities). Due to his involvement with the Nazis, the University Appeals Chamber categorized him as a "follower" in 1948 and he lost his civil rights and his professorship for three years. Bcoming emeritus in 1951 coincided with his rehabilitation and reinstatement under the 131 Act. Even after the war, he maintained his anti-democratic convictions. In addition to philosophical works, he also wrote local history and literary works. He was chairman of the Tübingen Museum Society for many years and was a member of the Tübingen municipal council for the Free Voters' Association from 1953. When he retired in November 1957, he became an honorary citizen of Tübingen. In return, he bequeathed his villa (Neckarhalde 31) to the city of Tübingen, which is now called the Theodor-Haering-Haus and houses part of the city's collections as well as rooms for artistic and museum education programs. In 1959, he was awarded the Grand Cross of the Order of Merit of the Federal Republic of Germany. On 17 June 2013, Tübingen's honorary citizenship was revoked by a resolution of the city council.
His nachlass and private library can be found in the University Library of Tübingen.
