What did Albert Einstein mean with his quote Dostoevsky gives me more than any Scientist more than Gauss?

Though he was fond of the American pluralism,Einstein was a pro- socialism, I mean in his political view. When we consider what Dostoevsky's master piece of novel, we found that how socialism was a failure to serve the society. For Dostoevsky disproves the theory of socialism, by Crime and Punishment, Einstein come to see more facts which were hidden from the reality( the social context). I think this what He probably mean.
