Does genius always leave us asking "how"? Not e.g. "why" like an eccentric creativity might.
So we don't ask of Marx "why" were you interested in Feurabach or a critical analysis of the economy, or sought to prove what he did, but "how" Marx was able to predict periodic crises or the collapse of liberalism. To be specific, I mean an exclamation about how difficult that was to achieve, rather than merely unlikely.
All I know about genius can be captured in the definition of the word, exceptional knowledge or creativity. And that Kant thought genius was inexplicable.
One correct answer to my question is that I am (trivially) right. But has any philosopher claimed anything like that, either about (great) philosophers, or artists: used the word "how" (by what means) and opposed it to eccentricity?
