Why did a brilliant philosopher call the dominant intellectual trend of his time rubbish?

In short: Ernest Gellner was a ferocious critic of linguistic philosophy, the Oxbridge orthodoxy that prioritized custom over universal truth. A lifelong crusader for critical rationalism, he argued that modern industrial society requires standardized, context-free communication, making nationalism a sociological necessity rather than a mere political choice or an accidental historical development.

Born in 1925 in Prague, Ernest Gellner was a witness to the turbulence of the 20th century. His family fled Czechoslovakia for England in 1939, escaping the rise of Hitler. After serving with the 1st Czechoslovak Armoured Brigade during the Siege of Dunkirk, he returned to academic life at Oxford. By 1959, he had published his first book, Words and Things, which launched a blistering attack on linguistic philosophy—a school of thought he believed was intellectually bankrupt because it treated community customs as the final arbiter of truth.

Gellner’s work spanned philosophy, sociology, and anthropology, always challenging closed systems of thought. He famously opposed the teleological view that humanity is inherently moving toward greater rationality, a notion he associated with his former colleague Morris Ginsberg. Instead, Gellner focused on the structural requirements of modern life. In his influential 1983 work, Nations and Nationalism, he argued that industrialization demands a high degree of cultural homogeneity. Because modern work is technical and requires constant retraining, the state must ensure that its political and national units are congruent to maintain economic progress.

Throughout his career, Gellner held prestigious positions at the London School of Economics and the University of Cambridge. He was known for his biting wit, his love of irony, and his dedication to his students. In his later years, he returned to Prague to lead the Centre for the Study of Nationalism, funded by George Soros, aiming to understand the resurgence of ethnic politics in post-communist Europe. He died in 1995, leaving behind a legacy as a vigorous, irreverent intellectual who refused to accept the comfortable orthodoxies of his peers.
