About the author
Latvian-British philosopher and historian of ideas (1909–1997), for decades the most prominent public intellectual at Oxford. Berlin's essay Two Concepts of Liberty (1958) drew a distinction implicit in liberal debates since the Enlightenment: negative liberty, freedom from external interference, versus positive liberty, freedom as self-mastery or self-direction. Berlin was more suspicious of positive-liberty traditions — from Rousseau through Hegel to 20th-century socialism — arguing that they could be used to justify coercion in the name of 'true' freedom. His distinction remains the most cited framework in Anglophone political philosophy.
