His most famous essay, The Hedgehog and the Fox (1953), interprets Leon Tolstoy's view of history through an Archilochus metaphor: “The fox knows many things, but the hedgehog knows one big thing.” Berlin classifies thinkers into two types: the "hedgehogs," who structure their worldview around a single central idea, and the "foxes," who have a more scattered and multiple perspective. According to Berlin, Tolstoy embodies both roles: by his talent, a fox; by his convictions, a hedgehog.
This essay has become an essential work for understanding the different approaches to thought and history.
