Meaning of what Einstein said... At least to my awareness.
Einstein famously said: "Imagination is more important than knowledge. For knowledge is limited to all we know and understand, while imagination embraces the entire world, and all there ever will be to know and understand."
Einstein was referring to creative imagination and not synthetic imagination. At least not synthetic imagination alone.
Edison is a good example but there are better examples but he is the most famous person so: When Edison created the talking machine 100% from creative imagination. What does that mean? That means he did not know how to do it. He filled his conscious with it, in waiting for plans to come to him through his intuition. I don't want to get religious but the plans come from God, or the universe, or infinite intelligence, or whatever the hell you want to call it. It is the only invention he did 100% through creative imagination. I have used it on meaningless things but it works. Basically this is the true definition of a Genius. Society thinks genius is some kid who is in college at age 12... No that is just someone who has a brain the processes very quickly. That is not a Genius.
The Wright Brothers were 2 bicycle mechanics from Dayton Ohio. Other people had spent millions are trying to figure out how to fly... But these 2 average brothers figured it out... "I can see it brother, I can see it". They saw it in their imaginations and filled their consciousness with it and guess what happen... They were lead to the answers they needed.
Henry Ford sent his engineers to work on creating the first v8 engine. Every 6 months they'd come back and say it cannot be done. Ford would say go back and try it some more. He was the one paying the checks but I guess he knew too that any idea held in the mind will began to cloth itself.
