But this is not word games. The statement is: "Nothing is absolutely at rest." Where is the word game in this statement? Or "all is in motion." These are clear statements. If people heeded Heraclitus who said this first thousand years ago astronomy would have advanced much faster. Astronomers built a whole geocentric system by assuming that the earth was stationary. They assumed stars were stationary. These turned out to be wrong. There is no absolute rest. The academic descendants of the same academics who believed in absolute rest now call themselves physicists and make the same mistake and assume that absolute rest exists.
