There are many kinds of knowledge. I mean many years ago it was much the same kind of knowledge; It was more a matter of who was in the know versus who wasn’t. But for some time now… OK let’s switch gears. There’s the knowledge we the common people have. There’s the knowledge the government has. And there’s the knowledge the government wishes to get their hands on. Many books today are filled with laws and information. They allow us to build this or apply that… BUT FOR EXAMPLE, WHAT TESLA KNEW TOOK THINGS TO A DIFFERENT LEVEL. WAS IT WHAT HE KNEW THAT DIFFERED? OR WAS IT HOW HE VIEWED THAT DIFFERED? Was it simply him looking in a different area or was it him looking at a deeper level? Or both? Operating a principle is one thing -being able to manipulate it is another. Explore its’ various dimensions? You take gravity for instance -theories abound about how it works, but we know it does. But to be able to counter it, or neutralize its’ effects… 🤷‍♂️
