Creativity is nothing more or less than seeing what was already possible. Everything we have built in the modern world was physically possible 5,000 years ago. It was the ideas and knowledge we lacked. Everything we will have built 100 years from now, if we survive, is possible now.
So much human misery depends entirely on human stupidity, and emotional dysfunctions of various sorts.
And actually, this raises the question: how much better would thinking actually become, once we consider that emotional blocks of various sorts have long impelled highly intelligent people into functional stupidity? Keynes was a genius, but he was also a fucking imbecile. He sought to create a plausible veneer for the establishment of Fascist economics, and that in turn because he did not grasp the value of political freedom for the masses, in turn because he did not recognize the possibility of individual moral development, this in turn because on some profound inner level he was completely stuck in a primitive state emotionally, all his life.
