Isaiah Berlin proposed an intellectual framework wherein thinkers are classified into 2 broad categories; hedgehogs, who view the world through the lens of a single defining idea and foxes, who draw on a wide variety of experiences and for whom the world cannot be boiled down to a single idea.
Examples of Hedgehogs: Plato, Karl Marx, Ayn Rand, Winston Churchill, Bernie Sanders
Examples of Foxes: Aristotle, Benjamin Franklin, Shakespeare, Warren Buffett, Barack Obama
