Say ‘fox and hedgehog’ and one is likely to think of several things. There is the old proverb, attributed to many people throughout history, that ‘the fox knows many things; the hedgehog, one big thing’. And, building on this idea, there is the philosopher Isaiah Berlin’s famous essay, ‘The Hedgehog and the Fox’. But these vulpine and erinaceous phrases and references are perhaps eclipsed by Aesop’s famous fable of the fox and the hedgehog.
