An ancient Greek poet wrote:
The fox knows many things, but the hedgehog knows one big thing.
Isiah Berlin expanded upon this idea in a famous essay
. He divided writers and thinkers into two 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.
It reminds me a bit of the idea of a generalist vs. a specialist. A generalist has a wide array of knowledge whereas a specialist has deeper knowledge in one area.
