Karl Popper, Winston Churchill, and the tradition of liberty among the English-speaking peoples

This paper starts by recalling a conversation of the author, then a young student, with Karl Popper in 1988. Popper argued that there is a 'British mystery' among the English-speaking peoples: their deep love of liberty, combined with a deep sense of duty, which was epitomised in the 20th Century by Winston Churchill. This paper argues that Churchill was a representative of an old tradition that goes back to Magna Carta of 1215. At its core is the protection of liberty to enjoy decentralised and peaceful ways of life and the corresponding allergy to revolutions and to schemes of perfection centrally designed.
