““Collins’s understanding of the Fox-Hedgehog parable is questionable from the start. He suggests that people who have had the greatest impact on humanity—including Darwin, Marx, and Einstein—were Hedgehogs, consumed with a single and simple idea, then pursuing it with dogged focus. But Isaiah Berlin made no such claim, observing only that Foxes and Hedgehogs were two different ways of looking at human experience. There have been great people in both categories. According to Berlin, Plato was a Hedgehog but Aristotle a Fox; Dante a Hedgehog but Shakespeare a Fox; Dostoyevsky and Nietzsche were Hedgehogs while Goethe and Joyce were Foxes. Collins’s assertion about Darwin is also doubtful: After all, Charles Darwin was raised as a conventional Christian and arrived at his revolutionary ideas about natural selection after decades of careful observation and reflection—challenging conventional dogma is not the sort of thing a Hedgehog normally does. It’s not even clear that Marx was a Hedgehog, as his favorite epigram—De omnibus disputandum (Everything must be doubted)—has a distinctly Foxlike ring. Many so-called Marxists may be Hedgehogs, but of course that’s a different matter.””
