” The earth is a system. A multitude of displacements and changes no doubt appear on its surface and hide within it; But these motions stay with a fixed frame; I mean that no matter how many relatively fixed points we find on earth, we cannot help but be attached to them, the events that unfold in the intervals then passing as mere mental views; the event would be nothing more than image successively combing through the consciousness of motionless observers at those fixed points. “

– Henri Bergson
