The fox knows many things, but the hedgehog knows one big thing.

For Isaiah Berlin, there is a fundamental distinction in mankind: those who are fascinated by the infinite variety of things - foxes - and those who relate everything to a central all-embracing system - hedgehogs. It can be applied to the greatest creative minds: Dante, Ibsen and Proust are hedgehogs, while Shakespeare, Aristotle and Joyce are foxes.
Yet when Berlin reaches the case of Tolstoy, he finds a fox by nature, but a hedgehog by conviction; a duality which holds the key to understanding Tolstoy's work, illuminating a paradox of his philosophy of history and showing why he was frequently misunderstood by his contemporaries and critics.
