““Hume applied his skeptical rigor to the concept of time. It made no sense, he said, to speak of time as having an absolute existence that was independent of observable objects whose movements permitted us to define time. “From the succession of ideas and impressions we form the idea of time,” Hume wrote. “It is not possible for time alone ever to make its appearance.” This idea that there is no such thing as absolute time would later echo in Einstein’s theory of relativity. Hume’s specific thoughts about time, however, had less influence on Einstein than his more general insight that it is dangerous to talk about concepts that are not definable by perceptions and observations.””
