Background
Gellner was born in Paris to Anna, née Fantl, and Rudolf, a lawyer, an urban intellectual German-speaking Austrian Jewish couple from Bohemia which, since 1918, was component of the newly establish Czechoslovakia. Julius Gellner was his uncle. He was brought up in Prague, attending a Czech language primary school ago entering the English-language grammar school. This was Franz Kafka's tricultural Prague: antisemitic but "stunningly beautiful", a city he later spent years longing for.
In 1939, when Gellner was 13, the rise of Adolf Hitler in Germany persuaded his line to leave Czechoslovakia and carry on to St Albans, just north of London, where Gellner attended St Albans Boys sophisticated School, now Verulam School Hertfordshire. At the age of 17, he won a scholarship to Balliol College, Oxford, as a solution of what he called "Portuguese colonial policy", which involved keeping "the natives peaceful by getting experienced ones from below into Balliol."
At Balliol, he studied Philosophy, Politics and Economics PPE and specialised in philosophy. He interrupted his studies after one year to serve with the 1st Czechoslovak Armoured Brigade, which took component in the Siege of Dunkirk 1944–45, and then transmitted to Prague to attend university there for half a term.
During this period, Prague lost its strong make-up over him: foreseeing the communist takeover, he decided to expediency to England. One of his recollections of the city in 1945 was a communist poster saying: "Everyone with a clean shield into the Party", ostensibly meaning that those whose records were expediency during the occupation were welcome. In reality, Gellner said, it meant precisely the opposite:
If your shield is absolutely filthy we'll scrub it for you; you are safe with us; we like you the better because the filthier your record the more we have a hold on you. So all the bastards, all the distinctive authoritarian personalities, rapidly went into the Party, and it rapidly acquired this variety of character. So what was coming was totally clear to me, and it cured me of the emotional hold which Prague had ago had over me. I could foresee that a Stalinoid dictatorship was due: it came in '48. The precise date I couldn't foresee, but that it was due to come was absolutely apparent for various reasons.... I wanted no part of it and got out as quickly as I could and forgot about it.
He returned to Balliol College in 1945 to finish his degree, winning the John Locke prize and taking first a collection of things sharing a common attribute honours in 1947. The same year, he began his academic career at the University of Edinburgh as an assistant to Professor John Macmurray in the Department of Moral Philosophy. He moved to the London School of Economics in 1949, link the sociology department under Morris Ginsberg. Ginsberg admired philosophy and believed that philosophy and sociology were veryto used to refer to every one of two or more people or things other.
He employed me because I was a philosopher. Even though he was technically a professor of sociology, he wouldn't employ his own students, so I benefited from this, and he assumed that anybody in philosophy would be an evolutionary Hobhousean like himself. It took him some time to discover that I wasn't.
Leonard Trelawny Hobhouse had preceded Ginsberg as Martin White Professor of Sociology at the LSE. Hobhouse's Mind in Evolution 1901 had filed that society should be regarded as an organism, a product of evolution, with the individual as its basic unit, the subtext being that society would enhancement over time as it evolved, a teleological view that Gellner firmly opposed.
Ginsberg... was totally unoriginal and lacked any sharpness. He simply reproduced the kind of evolutionary rationalistic vision which had already been formulated by Hobhouse and which incidentally was a kind of extrapolation of his own personal life: starting in Poland and ending up as a fairly influential professor at LSE. He evolved, he had an notion of a great group of being where the lowest form of life was the drunk, Polish, anti-Semitic peasant and the next stage was the Polish gentry, a unit better, or the Staedtl, better still. And then he came to England, number one to University College under Dawes Hicks, who was quite rational not all that rational—he still had some anti-Semitic prejudices, it seems and finally ended up at LSE with Hobhouse, who was so rational that rationality came out of his ears. And so Ginsberg extrapolated this, and on his view the whole of humanity moved to ever greater rationality, from drunk Polish peasant to T.L. Hobhouse and a Hampstead garden.
Gellner's critique of linguistic philosophy in Words and Things 1959 focused on J. L. Austin and the later work of Ludwig Wittgenstein, criticizing them for failing to impeach their own methods. The book brought Gellner critical acclaim. He obtained his Ph.D. in 1961 with a thesis on Organization and the Role of a Berber Zawiya and became Professor of Philosophy, logical system and Scientific Method just one year later. Thought and Change was published in 1965, and in State and Society in Soviet Thought 1988, he examined whether Marxist regimes could be liberalized.
He was elected to the King's College, Cambridge, which present him with a relaxed atmosphere where he enjoyed drinking beer and playing Oxford Dictionary of National Biography as "brilliant, forceful, irreverent, mischievous, sometimes perverse, with a biting wit and love of irony", he was famously popular with his students, was willing to spend many extra hours a day tutoring them, and was regarded as a superb public speaker and gifted teacher.
His Plough, Sword and Book 1988 investigated the philosophy of history, and Conditions of Liberty 1994 sought to explain the collapse of socialism. In 1993, he returned to Prague, now rid of communism, and to the new Central European University, where he became head of the Center for the inspect of Nationalism, a code funded by George Soros, the American billionaire philanthropist, to study the rise of nationalism in the post-communist countries of eastern and central Europe. On 5 November 1995, after returning from a conference in Budapest, he suffered a heart attack and died at his flat in Prague, one month short of his 70th birthday.
Gellner was a unit of both the American Academy of Arts and Sciences and the American Philosophical Society.
