There’s a celebrated proverb from the 7th century (BC) Greek poet Archilochus:
The fox knows many things, but the hedgehog knows one big thing.
Subsequent thinkers and writers have argued about what exactly Archilochus meant by the adage. Despite a broad range of interpretations, one thing is clear: these two animals employ very different survival strategies.
Foxes—at least the literary ones—rely on cunning and have a wide range of tricks at their disposal; they exhibit flexibility in the face of changing circumstances. Foxes are generalists.
Hedgehogs rely on a single remarkable trick—the ability to roll up into a nearly impregnable ball when threatened or attacked. This skill is unique, reliable, and wholly effective. Hedgehogs are specialists.
The philosopher Isaiah Berlin famously explored the dichotomy between foxes and hedgehogs in an essay from 1953:
Taken figuratively, the words can be made to yield a sense in which they mark one of the deepest differences which divide writers and thinkers, and, it may be, human beings in general. For there exists a great chasm between those, on one side, who relate everything to a single central vision…a single, universal, organising principle…and, on the other side, those who pursue many ends…the first kind of intellectual and artistic personality belongs to the hedgehogs, the second to the foxes.”
Berlin labels Dante, Plato, Hegel, Nietzche, and Ibsen as hedgehogs. Shakespeare, Aristotle, Montaigne, Erasmus, Goethe, and Balzac, he asserts, are foxes. Berlin is careful to note the limitations of the metaphor in noting that “it offers a point of view from which to look and compare, a starting-point for genuine investigation.”
Which approach is better? That depends on the predilection of the observer and their resulting interpretation. Half the fun is advocating for one side or the other and extending the metaphor as far as reasonably possible—an activity that, admittedly, invites a tremendous degree of creative license.
Business writer Jim Collins, in his book Good to Great: Why Some Companies Make the Leap…and Others Don't, explicitly invokes the hedgehog metaphor and writes that “if you cannot be the best in the world at your core business, then your core business absolutely cannot form the basis of a great company.” In other words, you have to embrace the hedgehog strategy and excel at “one big thing” to win at business. He dismisses foxes as “scattered, diffused, and inconsistent”—they can be good, but never great.
David Epstein, in his book Range: Why Generalists Triumph in a Specialized World , is inclined towards foxes. “Hedgehogs tend to see simple, deterministic rules of cause and effect framed by their area of expertise…foxes see complexity in what others mistake for simple cause and effect. They understand that most cause-and-effect relationships are probabilistic, not deterministic.” In an uncertain and constantly changing world, he asserts, fox-like traits are an asset.
Still others argue that the real trick is reconciling the two ideas. Historian John Lewis Gaddis, in his book On Grand Strategy relates novelist F. Scott Fitzgerald’s notion of ‘first-rate intelligence’ as “the ability to hold two opposed ideas in the mind at the same time, and still retain the ability to function.” Consequently, Gaddis argues for combining the best of each, a union of the “hedgehog’s sense of direction” with “the fox’s sensitivity to surroundings.” Why settle for one approach when you can embrace both?
As for me, I’ve long considered myself a generalist. Deep down, however, I’ve always envied the specialist. I wish I possessed that “one big thing” known by the hedgehog. I sometimes wonder if hedgehogs are equally envious of foxes or if their one thing is so satisfying that they don’t give it a second thought.
Erasmus discusses Archilochus in his collection of proverbs, the Adagia (1500). The Dutch philosopher concludes his commentary on foxes and hedgehogs with a different, but thematically similar, parable (with a cat standing in for the role of the hedgehog). It captures the bewilderment experienced by many metaphorical foxes:
Once the fox was talking to the cat, and boasting that he had so many skills at his disposal that one might say he had a bag of tricks: the cat replied that she had only one, to which she trusted in danger. While they were discussing this, there was suddenly a noise of approaching hounds. The cat leapt up into a high tree, while the fox was encircled and caught by the pack of hounds.
It figures that a fox, like Erasmus, would end his commentary with a grudging nod to the hedgehog.
