György Lukács (/ˈluːkɑːtʃ/; Hungarian: [ˌɟørɟ ˈlukaːtʃ]; 13 April 1885 – 4 June 1971) was a Hungarian Marxist philosopher, aesthetician, literary historian, and critic. He was one of the founders of Western Marxism, an interpretive tradition that departed from the Marxist ideological orthodoxy of the USSR. He developed the theory of reification, and contributed to Marxist theory with developments of Karl Marx's theory of class consciousness. He was also the philosopher of Leninism. He ideologically developed and organised Lenin’s pragmatic revolutionary practices into the formal philosophy of vanguard-party revolution (Leninism).
After the war, Lukács and his wife returned to Hungary. As a member of the Hungarian Communist Party, he took part in establishing the new Hungarian government. From 1945 Lukács was a member of the Hungarian Academy of Sciences. Between 1945 and 1946 he strongly criticised non-communist philosophers and writers. Lukács has been accused of playing an "administrative" (legal-bureaucratic) role in the removal of independent and non-communist intellectuals such as Béla Hamvas, István Bibó, Lajos Prohászka, and Károly Kerényi from Hungarian academic life. Between 1946 and 1953, many non-communist intellectuals, including Bibó, were imprisoned or forced into menial work or manual labour.
Lukács' personal aesthetic and political position on culture was always that Socialist culture would eventually triumph in terms of quality. He thought it should play out in terms of competing cultures, not by "administrative" measures. In 1948–49 Lukács' position for cultural tolerance was smashed in a "Lukács purge," when Mátyás Rákosi turned his famous salami tactics on the Hungarian Communist Party.
In the mid-1950s Lukács was reintegrated into party life. The party used him to help purge the Hungarian Writers' Union in 1955–56. Tamás Aczél and Tibor Méray (former Secretaries of the Hungarian Writers' Union) both believe that Lukács participated grudgingly, and cite Lukács leaving the presidium and the meeting at the first break as evidence of this reluctance.
In 1956 Lukács became a minister of the brief communist revolutionary government led by Imre Nagy, which opposed the Soviet Union. At this time Lukács' daughter led a short-lived party of communist revolutionary youth. Lukács' position on the 1956 revolution was that the Hungarian Communist Party would need to retreat into a coalition government of socialists, and slowly rebuild its credibility with the Hungarian people. While a minister in Nagy's revolutionary government, Lukács also participated in trying to reform the Hungarian Communist Party on a new basis. This party, the Hungarian Socialist Workers' Party, was rapidly co-opted by János Kadar after 4 November 1956.
During the 1956 Hungarian Revolution, Lukács was present at debates of the anti-party and revolutionary communist Petőfi society, while remaining part of the party apparatus. During the revolution, as mentioned in Budapest Diary, Lukács argued for a new Soviet-aligned communist party. In Lukács' view, the new party could win social leadership only by persuasion instead of force. Lukács envisioned an alliance between the dissident communist Party of Youth, the revolutionary Hungarian Social Democratic Party and his own Soviet-aligned party as a very junior partner.
After 1956 Lukács narrowly avoided execution. Due to his role in Nagy's government, he was no longer trusted by the party apparatus. Lukács' followers were indicted for political crimes throughout the 1960s and 70s, and a number fled to the West. Lukács' books The Young Hegel and The Destruction of Reason have been used to argue that Lukács was covertly critical of Stalinism as an irrational distortion of Hegelian-Marxism.
Following the defeat of the Revolution, Lukács was deported to Romania with the rest of Nagy's government. Unlike Nagy, he survived the purges of 1956. He returned to Budapest in 1957. Lukács publicly abandoned his positions of 1956 and engaged in self-criticism. Having abandoned his earlier positions, Lukács remained loyal to the Communist Party until his death in 1971. In his last years, following the uprisings in France and Czechoslovakia in 1968, Lukács became more publicly critical of the Soviet Union and Hungarian Communist Party.
