Foxes draw on a wide variety of experiences. For foxes, the world cannot be boiled down to a single idea.

Berlin's examples from literature and philosophy: Herodotus, Aristotle, Desiderius Erasmus, William Shakespeare, Michel de Montaigne, Molière, Johann Wolfgang Goethe, Aleksandr Pushkin, Honoré de Balzac, James Joyce etc.

Fox theories argue that intelligence is not a single, unitary quality but rather a collection of several distinct types of intelligences.

Howard Gardner's Theory of multiple intelligence is a fox theory par excellence.
