The fox knows many things, but the hedgehog knows one
big thing.” Archilochus “
The Hedgehog and the Fox.” Isaiah Berlin “
Foxes have different strategies for different problems. They are comfortable
with nuance; they can live with contradictions. Hedgehogs, on the other hand, focus on the big picture. They reduce every problem to one organizing principle.” Philip E. Tetlock “
Range. Why generalists triumph in a specialized world.” David Epstein
“
The fox knows many things, but the hedgehog knows one
big thing.” Archilochus “
