The law of gravity and gravity itself did not exist before Isaac Newton."...and what that means is that that law of gravity exists nowhere except in people's heads! It 's a ghost!"Mind has no matter or energy but they cant escape its predominance over everyhting they do. Logic exist in the mind. numbers exist only in the mind.

Law of logic, of mathematics are also human inventions, like ghosts."...we see what we see because these ghosts show it to us, ghosts of Moses and Christ and the Buddha, and Plato, and Descartes, and Rousseau and Jefferson and Lincoln, on and on and on.
