How can someone be called "brilliant" when he got virtually everything about economics wrong? Inquisitive? Perhaps. Witty, pithy? Probably. Knowledgable of history. A qualified yes.
But intelligence is the ability to set aside one's prejudices and see reality for what it is. If he believed what he wrote, then he failed the test. I'm tired of crediting the undeserving with "brilliance".
Keynes did not get virtually everything about economics wrong.
